Against All Odds and a Monster Awakens

Jon’s Z story is sadly alot like the other doom and gloom stories.  Thankfully after much love and a heavy therapy session at Specialty-Z there are no longer clouds looming over this Z.

Mods are as follows:

  • Built Engine
  • JWT 400 Cams
  • HKS Turbos (unknown size, possibly 2530s)
  • Tubular Exhaust Manifolds (mid-length)
  • ASH 2.5″ IC Piping & Massives
  • Larger Throttle Bodies
  • ASH Inlet Pipe Kit
  • Border 850cc Fuel Kit
  • SZ modified 2.5″ SS Downpipes
  • Custom 3″ Test Pipes & Catback
  • Twin Disc Clutch

After fixing the tremendous amount of issues we began to tackle this Z on the dyno for some data logging and tuning.   After a few pulls we uncovered more issues that needed addressing.  The Z came us with solid intake cam gears.  We installed a set of BDE Intake Cam Gears to revive Nissan’s VTC system.  Unfortunately we found that the VTCs were still not working.  We pulled the valve covers and found that the check valves were not installed in the back of the cams.  Adding the much needed check valves did the trick.  We also found that the fuel pressure was abnormal, very abnormal.  It was causing tuning grief and running too lean at 3300 RPM up until 4200 RPM.  This was remedied by untangling old bad work.

Fuel pressure reading on the lowest graph.  You can see how its running base fuel pressure up until 4200+RPM.  This is not good as you can see how lean it gets.  You can also see how it hurts power causing a nice dip.

Here is the graph (red run) after we fixed the fuel pressure issues.  The old bad run (blue) is displayed to show the obvious differences.  35 torque and 35 whp gain.

This graph shows the dramatic difference that a working VTC system can make.  The blue run was prior to fixing the VTCs.  Red is after with the VTC system working.  75 torque and 57 whp gain!!!!!!  Look at how the turbos react (boost curve).

The most impressive thing about this Z is its ability to make power on 91 octane and its strength against the evil California fuel.  You can’t hold it back.  It will go all the way.

If you can’t see it clearly enough, that graph says 564 whp & 501 torque.  It also says peak boost pressure of 20 psi.  All this on 91 octane.  A freak, an anomaly, a monster.  This Z gets to have its cake and eat it too.  It also takes other people’s cakes and eats it too!  It has amazing low end response, top end power, and makes a shit load of safe reliable power on 91 octane.  So much power that Jon declined to make any higher octane tuning.  Really?  Too much for you eh, Jon?

Super Street Z32

Over a year ago we took Danny’s Z32 from a tired Z to a refreshed pepped up Z.  We went with a brand new Nissan shortblock and Stage 1 SZ heads (KISS).  We added a set of MS Manifolds, JWT  Sport 530s, and our full 3″ SZ Exhaust from the turbos back.  Stock cams, intercooler piping, Stillen ICs, and stock TBs were retained.  We also added our SZ flywheel and Max Street Clutch.

The old and very tired engine.

The new engine coming along nicely.

Fresh valve covers and MS Manifolds 🙂  I didn’t take more pics of the build or even the car so this is all you get,  unfortunately.

Breaking it in on the dyno.  It should do better now that its all broken in since the past year.

Back for Boost

The last time we saw Jesse we had just performed a tune for his NA bolt-ons. Yearning for more power than the NA bolt-ons could provide we went to work installing a GTM Stage 2 Twin Turbo Kit.  The kit features the use of Garrett GT2860RS’ with .86 turbine housings.  An angle mounted FMIC, cast manifolds, internal wastegates, TIAL BOV, 2.5″ down-pipes that allow the use of standard test pipes or even the factory cat pipes for smog purposes.  We installed a Walbro 255 fuel pump and DW 600cc fuel injectors to supply the needed fuel.

We removed the factory engine oil heat exchanger and added a GTM 25 Row Oil Cooler.  We made our own custom mounts to clear the intercooler.

A look from underneath with the turbos mounted.

Here’s the graph once we finished our tune.  The blue run was Jesse’s best NA run.  Red is with twin turbo power.  A peak gain of almost 120 whp and 85 torque.  This is accomplished only on wastegate spring pressures that make anywhere from 4-6 psi throughout the powerband.  We stopped here so that the stock engine could live a long happy boosted life.  When Jesse’s ready for more power he can easily have it with the potential that this kit can offer.

Big Turbo Power!

Mr. Rob from Virginia sent us his Z32 for some big turbo loving.  His Z came to us with stock turbos, stock injectors, stock engine, just about everything stock.  It was essentially a Stage 3 Z.  We performed a leak down and compression test on the stock long block to find it was in exceptional shape.  Rob didn’t plan to run race fuel but wanted big power on regular pump fuel which is 93 octane in Virginia.  The stock long block was up to the task for this.  We installed the following parts:

  • SZ EXP-95 Turbo Kit
  • 300Degree\SZ 850cc Fuel Injector Kit
  • MSP Manifolds
  • JWT 500 Cams, HD Valve Springs, & BDE Intake Cam Gears
  • SZ 3″ EXP Downpipes
  • SZ 3″ Test Pipes
  • SZ 3″ Single Oval Catback
  • ASH 2.5″ IC Piping
  • ASH Massive V3 Intercoolers
  • Z1 58mm Throttle Bodies
  • Brake Man Big Brake Kit

Motor ready to be dropped in.

Massive Intercoolers and Brake Man parts installed.

Finally after completing the mechanical work, it was time to tune and make boost!  These turbos are capable of easily making over 30+ psi on race fuel which can easily translate to 800+whp.  For Rob, it wasn’t about the maximum output but ultimate power on ordinary pump fuel.

590+ whp on pump 93 octane fuel on 17-19 psi.  Not bad!  Rob’s original TT fuel pump is struggling to keep up at this point.  With some cam tweaks we can raise the entire power-band and smooth out delivery.

Enjoy the ride Rob!

Vortech’ed G

Jason’s G35 came to us for more power and in turn we obliged by adding a Vortech SC Kit.  Fueled by 600cc injectors and Walbro fuel pump.  HKS catback and stock cats draw out the exhaust.  Power is transferred to the wheels through the stock 5-speed automatic with a valve body upgrade.

Our final tuned numbers when allowed to cool.  After a couple passes it heat soaks quickly with power dropping to the 350s.  The blue run is a minor bolt on equipped G35 AT.  Huge difference in power all over the place!

Resurrected from the depths of despair

The following Z and its owner have been through trials and tribulations.  Joe purchased this Z over 6 years ago as a simple (slow) and clean NA (non turbo for those who don’t know).  At the time there was no intention of making the Z “fast” but more of a show stopper.  Joe set out acquiring bolt-ons for NA performance along with a plethora of aesthetic improvements.  However as time past, Joe couldn’t get the thought out of his head about the twin turbos.  Two almost “mythical” units that could provide him a powerful Z.  The lust of more power bounced through his head.  Not knowing enough, Joe set out to research his quest for twin turbos.  After much deciding and advice of other people, along with a good chunk of cash Joe purchased a front clip and a large assortment of parts to complete his project.  The front clip brought a pleasant surprise for Joe as the engine had strapped to it not only twin turbos but an aftermarket set.  That aftermarket set turned out to be a JDM Blitz Turbo Kit equipped with Triple K turbochargers.  The kit came complete with cast exhaust manifolds and external wastegates.  The transplant began at another shop 5 years ago and didn’t fair well for the Z and Joe.  The Z sat for many months untouched and when Joe received a call from the shop informing him the car was running his heart skipped a beat.  Unfortunately the engine was running poorly, enough that it fuel hydrolocked and finally gave out.  Crushed with a blow to his ego and wallet Joe set out to repair the engine and had this time another shop work on the Z.  This time the car sat for almost a year without being touched.  Empty promises can only go so far and they definitely won’t get a Z running.  Adding insult to injury during its stay at that shop parts went missing that yet again would have to be purchased for a second and even a third time……………………..

Joe wrote me an e-mail sharing his story from the beginning.  I took out any names of people and shops  mentioned.  In Joe’s words:

“In 2003 I crashed my 1988 RX-7 so it was time to buy a new car, I had seen several 300zxs on the road for a long time, but they looked expensive and out of reach.  One day I went with my friend to pick up his car at his mechanic’s shop, and there it was…….. at the shop a pearl white 300zx being worked on (beautiful ) so I started looking for joez, after about 9 months in April 2004 I found her.  She needed some minor work  and so  started my project to fix her.  I was working in real estate so I had plenty of money to take care of her, and started my car club (team shift) the same year and started to go to car shows, that’s where the need of fixing her came in an order to compete.  It started with an e-bay $40 cold air intake, clear turning signals, clear rear side markers, chip strut bar…etc.
At a winter 2004 car show (team transport / toys for tots) I won best of show ( proof of trophy up on request…lol ) so I got hooked.
In mid summer of 2005, after losing back to back in 2 different car shows to Robert’s Red 300ZX NA;  I decided to repaint her and fix her to the point where nobody could copy my designs.  I decided to spend an unlimited amount of money to put it out reach and force my competition to spend more money in order for them to keep up.
These is where my trials and tribulations started, and very soon God let me know I was doing it for all the wrong reasons and the wrong intentions…let me explain…

After the inland empire show I went to a body shop for what I thought  was going to be a $3500 paint job.  It turned out to be a $18000 custom paint and body work.  After it was done she went to a performance shop where the guy that specialized in Zs got deported and not even within half in hour after she arrived from the body shop, a guy that was working on transmission on a car forgot to put the e-brake on that particular car and it rolled in to my car.  That shop never paid for the damage that amounted to $2500.  Right away it went to another performance shop.  At this place she spent 8 months and they couldn’t get it started.  Apparently this was due to them not plugging the ECU in properly (pistons no. 5 & 6 got flooded with fuel and blew a $4000 jdm front clip).   I didn’t even know about this until the car was towed to my house.  I decided to start the vehicle after paying good money to discover the bottom end was gone and I had already paid them $4500 for the job.  They also never paid for the damage and blamed another shop.  I had to purchase another jdm short block for $1200 and from there I took it to an interior shop.  Once again a simple $300 job turned into a $7000 job.  At this particular place, the owner jerked me around for about a 10 month period.  He ended up closing shop, took my money without ever telling any of his “customers”.  I showed up to find the gates closed and our cars locked.  The owner was no where to be found.  My interior never got done and about 80% of the interior was stolen including my stereo system and boost controller.   Chalked up another loss of $6000 not including the stolen parts.
From here I went to a Nissan dealership where I thought it would get done right.  The Z spent another 13 months and they couldn’t get her started either.  My battery, blow off valves, all the air conditioning pipes, radiator, etc. were stolen.  Thankfully the dealer compensated me for the thefts.
From there it went to another shop where she spent almost another year and got taken for another $6000.  The Z never ran right and then I finally decided it would go to Specialty-Z.
Here it was a bitter sweet experience.  At the beginning they told me almost all the work performed was wrong with joez.  After having spent all this previous “good” money on other shops brought me to a breaking point.  I was ready to throw the towel in and set the car on fire!!!!  However…… after going into Specialty-Z at the beginning of Jan 2011 and wrapping up mid summer 2011, I took her to Vegas and fell in love!  Soon after Seb and Greg were done with her fixing all the previous work from other shops, the Vegas trip was the best road trip ever, she ran awesome!!!!  All I can tell you is that Greg and Seb are angels sent by God to specifically work on Zs.  There at Specialty-Z is where I fell in love with joez all over again.
Moral of the story is God has his time when He is ready to reward you, and He will !!!
Don’t do things out of pride, but for the love of it.
Stay humble.

I’m sure I left a lot of other bad details and bad experiences,  but who wants to remember that when she already found a home (Specialty-Z )”
Thx Seb
Thx Greg
God bless
Joe G

I wanted to share this with all of you because I have never heard of such a horror story.  When Joe brought us his Z he was ready to give up and break down.  His health had been greatly affected by his experiences.  I was afraid to share more bad news the more I tore into the Z.

Thankfully this story ends very happily with Joe and his Z riding off into the sunset………

Some pictures from some of the work we performed.

We fabbed up a custom set of downpipes and used Tial W\Gs to replace the old leaking Blitz units.  The downpipes cone out to 3″.  We also routed the external wastegates back into the exhaust.   You can only imagine what came off of this Z.

Joe brought us a Brembo kit that fit terribly.  We had to machine the caliper bracket as the caliper didn’t even come close to sitting evenly on the rotor.  We replaced all of the adjustable suspension components with SPL units.  A good majority of the suspension was improperly set and left loose ruining the parts that had been previously installed.

On his last major visit to us we installed 2.5″ IC Piping, Massives, and Z1 TBs.  The headlights, fog lights, and turn signals were sent off to Mike @ clearcorners.com.  Mike does amazing work.

On Joe’s first visit to us we got the Z running properly off the 9 psi wastegate spring.  The car was in such bad shape it couldn’t make a full 4th gear pull without cutting out.  His existing AVC-R boost controller would also reset itself at any given moment.

On his second visit, we focused on adding more power now that we had a solid foundation to work off of.  We added 2.5″ IC piping, Massives, TBs, and a Blitz i-Color Spec-R Boost Controller along with our SZ Tune Switcher.  This is a before and after with the above added parts.

Finally we tuned on 100 octane fuel.  Since the Z has high flow cats we couldn’t run it on Q16.  Congrats to Joe on his beautiful show stopper Z.

Merry Christmas and Happy New Year to all!

GTM Stage 2 SC

We had the opportunity to get our hands on the new GTM Stage 2 SC Kit.  The great thing about the kit is that its very quiet not like your typical Vortech units and the way Sam@GTM has designed the kit you can’t even see the blower with the hood open.  Making it a much slicker and sleeper look.  The heart of the kit is the Rotrex C38 that delivers in Kevin’s setup 7 psi.  We suggested a larger pulley to keep boost down to a very safe level.  However Kevin’s already thinking about having us install a smaller pulley to make 9 psi!  While we were at it we also added GTM’s AT Trans Cooler and Engine Oil Cooler to work with the SC kit.

Just a turbo driven by a belt 😉

We installed the kit on Kevin’s 2010 G37S Coupe AT.  Kevin already had an Invidia catback to add to the mix of mods.  We added a set of Fast Intentions HFCs since his ART pipes wouldn’t clear the new larger tranny cooler fittings and lines.

Believe it or not, this is where the intake sits since the blower sits low by the engine.  Sam claims and has done testing that inlet air temps aren’t as bad as they would look by having the intake sit right below the passenger exhaust manifold.

Quad cooler monster.  On the passenger side resides the trans cooler, top center the SC cooler (SC has its own oil system), below it is the intercooler, and on the driver side the engine oil cooler.

Nissan\Infiniti has made it hard(er) to service their automatic transmissions.  I can see how this would prevent the regular guy from using the wrong fluid and protecting the trans.  This is where you fill and check the fluid.  No dipsticks here!  Sorry Jimmy.

Installed and ready to make boost.  You can see the SC oil reservoir by the coolant overflow tank.

It’s hard to see what’s behind the bumper.  It’ll make you want to think twice when pulling up to a new G.

460 whp on 8.5 psi.  Time to light up the tires.

Eli’s tune on 91 octane, peak power at 14 psi with a minor spike to 16 psi.

100 octane peak power produced on 17 psi.  Very good looking power\torque curve.

The cherry on top….. Q16 to crush our record on 2560R turbos.  Making easily over 600+whp with the addition of “breather” mods.  A job well done to Eli.  You came a long way! (not distance, although its a little bit of a drive).

R32 GT-R Update

Its been awhile since we tinkered on the R32.  After waiting for a custom twin carbon clutch from RPS  we were able to dust Godzilla off.

This JUN RB27  had some changes with its catch can and we added a Braille battery.  The battery was previously in the rear, but this required us to run a cut off switch in the rear (NHRA rules).  Forcing us to drill a hole in the bumper…. no thanks!  Some fuel upgrades will be coming with an addition of ID injectors.

RPS used a trick Porsche style hub and floater disc to keep noise down and engagement super smooth.  Note the inner disc right outside the hub  This is the discs “attached” together.

You can see how this flywheel side disc (key) looks without the outer disc on top of it.

The “outer” disc.

Lastly the aluminum carbon “insterted” flywheel bolted in with ARP bolts.

At the same time we converted the pull style setup to an internal “race” slave cylinder.

Following the clutch install we sent the GT-R to the body shop.  We found “old” rear damage that had been covered up.  You can see it was rear ended at some point in its Japanese island life.

Getting stripped down.

Interior stripped down and prepping the cage for paint.

The front bumper particularly needed much work.

Painted and getting polished.

We had the FMIC painted black for a stealthier\cleaner look.


The final wipe down.

Methed AT Addict ;)

Mr. Billy S brought us his Z32TT AT last year with some basic mods.  His Z came equipped with JWT Sport 500s, stock auto trans, stock intercooler piping, Nismo 555cc Injectors, stock exhaust manifolds, Chinese 2.4″ down pipes, stock cat pipes, Borla catback, Selin Dual POP Kit, and Snow Performance Meth\Water injection kit.  Need less to say the dyno results weren’t spectacular with his list of mods.  We took the time to “educate” Bill on how to better improve the efficiency of his setup without having to make any “huge” changes.  Throughout the course of a year, Bill put on 2.5″ IC piping and we installed a built SZ transmission, SZ 3″ 4-Bolt DPs, SZ 3″ Test Pipes, and SZ 3″ Catback to top it all off.  Bill also stepped up the nozzle size on the Snow Performance kit.  Exhaust manifolds were not upgraded.  Bill is currently planning his next “big” upgrade.  Some of us just can’t get enough.

This dyno graph shows you the difference from his old mods to the new mods.  If you read the paragraph above you’d know what the differences were.  The after shows a dramatic difference across the entire powerband with the largest gains found in the mid-range.  At 4k we freed up another 70 torque and 50 whp.  This is on 91 octane.  Click the graph to see its full size.

This graph again shows you the difference between the mods and this is on meth injection (Boost Juice).  On his old mods and running meth we found NO added power from turning up the boost.  This is when efficiency comes back into play.  No need to run more boost and make the same or less power.  The after is very impressive.  Running meth and 91 octane fuel with the new mods we saw 110 whp & 105 torque gains at 5500RPMs.  We were able to run higher boost with the new breather mods and make power like planned.  This won’t be the last of Mr. Sutton’s quest for more power.
