Oh yeah I never thought of that. Thank you for asking this great question twice and contributing to the 370Z community. We all appreciate your help.

Looks like you put a Stillen kit on just a month ago. You will be asking for an upgrade when your 380whp gets old, which happens to all of us.

*EDIT* 01-20-17 Optimiser bought my kit a few months ago :roflpuke2:

hahahhah.

I'm not greedy and will never want more HP than what I get now, it's more than enough. I'd rather leave things alone and have the thing stay reliable and not stuff around with it endlessly.

Then you shouldn't have bought a Stillen kit. :rofl2:

A properly designed air to air setup will make the Stillen kit FAR, FAR more reliable. The off the shelf kit measures air temp pre-compressor. I'd bet folding money that's the reason the Stillen kit has blown more motors than turbo kits have. Switching to a blow-through MAF setup will eliminate the major risk factor with these kits - the ECU having no clue how hot the intake charge is.

Even running the stock stillen kit is risky in my opinion.

After seeing swiss's data logging.

As chuck said, this kit spells disaster.

:iagree:

The numbers he posted were terrifying. That kit is a time bomb the way they designed it.

You mean is risky the way designed by stillen. :tup:

I tracked mine for two years with no problems some how. Swiss has a 9 lb pulley I think but I would imagine my temps would have been close in the Florida heat.

I need this in my life ASAP !

Same here for about 3 1/2 Years
(no DD, always just for fun, in the swiss Alps and on the fast lane ;))

+ 9 lb pulley
+ upgraded Impeller

11- 12 Psi on the stock engine (Too much for the OEM block with this Kit)

Why now only 9 Psi?

- Brian Crower Stroker Kit (4.08 Ltr and 10,5 :1 compression rate)

That will change in April:stirthepot:

I have already done a track day with the SC and no issues whatsoever.

Have you missed reading any threads on this kit besides this one? It has been stated numerous times that the kit is fine at the power levels your making. Your on the 8psi pulley and im guessing the ultra safe stillen tune. That is what stillen designed this kit for. Now bump up just 1 more psi and you have to sign a waiver that it jeopardizes the kits reliability. They know the kit wasn't designed to make a bunch of power. But it can make great numbers with some better cooling and maf placement. No carb cert though.

Its hard to say, maybe because of the lower compression on pistons?

But in theory your boost should be the same, now that I think about it.

Exactly. a2a is the only way.

A2A may be the better way but it is not the only way.

Most all of the car makers that offer SC use a water cooled system. They offer the system as a highly developed off the shelf system. If you mod their system the warranty goes away.

I agree with you that a better solution for an open source tuning would be a2a but the stock system seems to be fine. The tune is another story.

I am planning on installing the Stillen kit in June, stock with the canned tune. As soon as it has been tested for leaks and any problems it will go to a tuner and get a proper tune. I have no plans on pushing the kit to higher boost. If I ever do, I will look into a complete solution, not just installing a 9 psi pulley. You have to do your homework if you are going to deviate from the designed system.

Thanks to all for your inputs. This is a great forum!!!!
