yes the tune is more important than nething but a high boosting s2k, say higher boost than the super chargers can run, would not be as reliable as a comptech or vortech, hey dont get me wrong im going turbo, my kits on the way. and yea im gonna run that 3037

i don't know why people keep mentioning reliability... if you wanted to run the 3037 at 7 psi it'd be just as reliable as the supercharger...

i mean you have the extra heat sinking and that gets released into the engne bay but the turbo is liquid cooled in two ways... what's this issue of reliability?

You know i hang out with a bunch of rsx and 350z guys. and when i tell them i will boost about 5-6 psi on the stock block they are so determained that my engine will blow up. and im asking myself whats the difference in boosting it with a sc and a turbo.

if u run the same boost its just gonna hit full boost way sooner ona turbo, sc dont hit it til redline, and i wasnt saying a 7 psi turbo would be less reliable than a 7 psi sc.

is it possible to get a Roots charger for an S2K?
also i thought for low psi turbos would not compare to the same grade sc...

not yet at least, although there have been talks for a long time. right now, you're stuck with the centrifugal. And a turbo will pretty much always be faster than a centrifugal of similar psi. The powerband is much fatter and you make way more power earlier.

I'm running a GT3076R on my F22. It will hold boost steady all the way to redline. (dynos don't show that because I asked the EMS to decrease boost from 16 psi to 10 psi as I got closer to redline since I was out of fuel system). I have made 443 whp and 363 lb-ft. It's a fantastic turbo. I'd like to try to break 500 whp with a set of larger injectors on my new fuel pump. I think it might be possible on pump gas on a dynojet

on an evo it's different, rev limits are generally 7-8k depending on if you're road or drag racing. that means if boost comes on after 4k you only have 3-4k rpms to work with... that sucks. defnition of peaky. so with evos you see people begging the fast boost up bag more.

if you guys really want a fast boost up car then consider the 3076, also known as 52 trim 3052, 3037 (hks variant). as long as you're using a kit you can bolt up any t3 flanged garrett turbo. the 3076 is used by most evo track hounds as a favorite but it will never produce the high horsepower numbers required to take down say... a skyline on the roadcourse.

notice how that xsengineering skyline always beats the evos cuz it's running 600+ hp.

Are you speaking from experience? It doesn't sound like it.

How is a power band 1000 rpm less than an s2000's peaky? That's retarded. A peaky power band rises then falls, hence the peak. That's caused by a turbine that's too small, not your rev limit.

Next it's a skyline always beating evos on the road course? WTF? Which road course? I really hope you aren't just talking about that best motoring american touge crap. It's just sad if you are.

A GTR has another .6 liters of displacement. Of course it's going to be able to run bigger turbos and still keep a decent power band compared to a 2 liter.
