Winters NISMO

This black Z34 NISMO came to us in need of a few things.  The owner complained of high oil temps even with his 25 row aftermarket oil cooler in city driving.  We designed and fabbed up a nice worry free solution to this.  We upgraded to a Stillen Gen 3 Intake, tuned the Z, and finally upgrade the rear end gearing to 4.08s.  Everything went smoothly and all the upgrades made nice improvements in the Z’s daily activities.

We had a few hurdles to conquer.  The first was getting by the front (NISMO only) brace.  You can see it in this picture running along side the front of the oil cooler and behind the fan.  Done with a little magic 😉  We used a very high quality SPAL pusher fan controlled by a thermostatic switch.  We opted to go with an 190 degree ON.  So as soon as the oil temps hit 190 degrees, the fan will automatically turn itself on.  We installed the temp sensor for the oil control directly into the oil pan (bung welded).

Looks almost factory.

NISMO factory tune with only the Stillen Gen 3 for mods.  Already running extremely lean.  This would only get worse with an aftermarket exhaust.

Tuned run.

The owner of this NISMO is happy to report that with the e-fan mod the oil temps are much cooler.  Here’s what he had to say:

Wow. Just wow.  The fan works great! Driving around West LA yesterday in stop and go traffic the temp got to about 200. That is vs. the 220-230 that I would normally see in that traffic in 70 degree weather. At a long stop light the the temp (as you mentioned) went down. That little fan must really move some air.

The new final drive gearing also helped give more kick in the pants feel, accelerating the Z quicker.


Over the past weekend John Garrison was racing his red Z32TT at the road course and ended up upside down.  Thankfully John came out with no injuries.

Here’s what John had to say about the incident:

hey guys,  wanted to let you know that I am ok, aside from some soreness.  Last session of the night event, got off line.  There was no run off area, just about 10 feet of sand then a tire wall.  The Z hit the tire wall and caught, then just launched it.  People say 3 1/2 flips, did not feel like it, crazy.  Ended up upside down, the partial roll bar keep the whole top of collapsing on me.  Won’t go back on track without a full rollbar.  Engine, drive train, exhaust all seem to be ok (still have to dig into it), have a rolling chassis that I am going to transfer everything into.

He also added:

no problem, stress the importance of safety gear if anyone goes on track.  I had a partial roll cage but will not go on track without a full one again even though I walked away from it without any injury.  thanks

Its a miracle John walked away clean.  Thank God!  Safety first.
