and btw steve, we still doing the cats tomorrow? what did you find out from autocrafts?

With regards to future upgrades.

All you need for the stillen kit is a different pulley and supporting mods; with GTM you need_______________?

I really wish the Stillen kit had something to make the engine bay look "complete".

Upgrades are good for those that want it but most will stay stage 1 due to emission tests, longevity and all. So if you dont plan to upgrade then that isnt a factor, but for some it will be so it will be a factor to some. Since I plan to stay stage one it wont be in my factoring.

This is not true for emissions. Going up 1 or 2 sizes (well, down actually to a smaller pulley on the blower) with proper tuning (and CATs still on the car) will pass every sniffer test out there. Specifically to California and visual inspections - you would have to go to a smog testing center that actually knew the correct diameter of the stock pulley and remember to measure for it. Same with getting a hood popped by a cop. This is really a non-issue. Absolute worst case is you change pulleys and get reinspected.

As to additional wear on a vehicle, we can look to the 350z community and see how many people went to atleast the 3.12" pulley as an upgrade and how the engine has held up.

So why arent stage 2s carb legal? If I buy stage one and upgrade to stage two Im still in legal limits?

Guess you are just going to have to wait to see the differences in the Stage 1 kit vs. Stage 2 and Stage 3.

This topic has been beaten to death...one person says

-1 GTM because you have to change compressors

another says:

-1 Stillen because you are buying a compressor but not using it to it's full potential

another says:

-1 GTM because it's going to cost more to upgrade (with absolutely no supporting facts to prove this by the way)

It all really boils down to if you want a Supercharger and aren't planning on upgrading again later then pick the one you want based on something else...

If you want to upgrade later than you really need to wait and see all the options for upgrades...

...hell we don't even know what Stillen's upgraded kits cost for parts OR labor either...so you really can't make an arguement for one company over the other.

text or call me in the morning, the job should only take us a few hours max.

you got any steel wool left? I have the bolt breaker spray but no wool.

Red370 · 03-12-2010, 02:15 PM

yeah, got a shytload man. BTW, we got another 370 on post, Lemers is his name on here, its the purple one.

Id like to see that color up close.

Zsteve · 03-12-2010, 02:22 PM

Now we have a good battle going on! Here is my chart with the new numbers:

Keep in mind Stillen had an aftermarket CBE and GTM did not (GTM we need a new dyno with CBE please).

Numbers are still very close and if GTM does a dyno with a CBE I think their numbers will be slightly higher over all but not by much, so its down to price and preference, and for me if the Stillen cooler is keeping things as cool as a FMIC will.

Stillen has a self lubricated SC, does GTM?

RCZ · 03-12-2010, 02:24 PM

More peak power and from what I can tell at least the same, if not more torque at every RPM level. Less boost, bigger supercharger on the Stillen kit. That means that the Stillen is blowing colder air from the get-go. Then a huge intake air temp drop due to their very efficient intercooler. On top of that, the Stillen kit is very easily and cheaply upgradable to make more power.

The price is damn close too considering the completely custom intake manifold and the air-to-water intercooler.

Right now Stillens TQ avg from 4k to 7K is 275 and GTM is 270, add the CBE should be higher.

I think with a CBE the GTM will be about the same to their peak numbers and probably have a better TQ avg.

Does a .1 difference in boost really mean anything performance wise?

So with a bigger SC its blowing cooler air to start with? And does that mean its not in its max efficiency range?

Im still on the fence with the cooler efficiency, I want to see intake temps and compare them to the GTM intake temps.

Its gonna be a tuff decision.

Zsteve · 03-12-2010, 02:53 PM

So when we are driving between the 4K and 7K rpm range what is going to make us go faster TQ or HP, if you had to pick only one?

RCZ · 03-12-2010, 06:21 PM

Buying and installing a new compressor housing is always going to be significantly more expensive than buying and installing a pulley.
