my first step -_-
 

Hello every body ,,

Im a new here and this is my first thread . .

i want an advise for part ( with 10000$ balance ) to make a 500 whp on stillen sc . .

Oil cooler ?? Impaller ?? Cog ?? Flywheel ?? Clutch ?? headers ?? Test pipe ?? Fuel system ??

Thank all and welcome :p

If the Stillen kit is part of that $10k your budget is too low. Otherwise, nobody can tell you since nobody has ever made 500whp on the Stillen kit. My guess would be upgrading all the pullies, new fuel system, meth and a really aggressive tune.

:iagree: if you NEED S/C, go GTM, if you want turbo, there are a few options

If you have a stock car, $10k isn't enough money for 500 whp. It'll be $15k in parts, plus labor. Plus, shipping to your part of the world probably isn't cheap. Go look in the Finished FI Builds thread for a better idea of what you need.

Im already have a stillen sc kit with Osiris tune and a result is 418 whp and 331 wtq with stock exhust and fuel rail . Not enough for me :p

Ok, then you might be able to make it happen for $10k if it really can be done.

Thank u bro , I'm already have a S/C . .

Let's see, my guess would be upgrading:
Injectors/pump (maybe a fuel return system)
MAF piping
Heat exchanger or a custom air to air intercooler with new piping
All pullies/cogs
Meth injection
Appropriate exhaust to give you just the right amount of backpressure but not choke the motor

My gut feeling would be that it would be easier to sell the Stillen kit to someone who's ok with 400-450whp and buy a GTM stage 1.5 SC kit.

I think that there are people out there who have made 500rwhp with that kit. Hidden in the woodwork though.

I know with upgraded impeller. Some big injectors, and like Chuck said, a really aggressive/ supporting tune, it can be done but... the Stage 1.5 from GTM may be a better option.. or the new Twin SC setup. :tup:

What the difference between a gtm and stillen ??

GTM's sc kit makes a ton more power. It's a better engineered kit. Stillen uses a good blower, but skimps on everything else like fuel, intercooling, etc. We have never seen a Stillen kit make 500 whp. It's common for GTM SC kits to make 500 whp. My advice would be to sell the Stillen kit and buy the GTM, unless you're the kind of guy who wants to be the first to do something.

Swiss370 has probably one of the better Stillen SC setups and has upgraded a lot: http://www.the370z.com/forced-induct...70z-swiss.html

There have been some who have gone with the Stillen SC with the goal of 500whp and all have sold their kit and moved onto another option. If you want to stay SC then GTM is your only option but if you want to migrate to TT then you have GTM, Fast Intentions, and Greddy.

You could probably sell your Stillen and buy a GTM and install it for $10k, because I assume you already have all the supporting mods

Im going with ur advise .. thanks alot bro .. but how many whp in gtm sc stage 1

Most people seem to go with the Stage 1.5 or 2 if they're looking for the kind of power you want. Give Sam at GTM a call and he'll talk you through all of the differences and what would be best for you.

Ok this is what I was going to do with my Stillen kit before I sold it

850cc injectors
340lph fuel pump

Redo the pipping and make it a front mount inter cooler kit

Put the maf's near the throttle body (behind the blower) were they should be

Upgrade the impeller and go with a cog setup

Maybe even go as far as returning to the stock intake manifold

Look at the 350z and g35 guys with the vortech kits they make good power

Stage 1 will top out around the mid 400s without getting into a bunch of other upgrades. I am sitting just above 400 with a GTM stage 1 SC and getting a retune this Friday to hash out a few minor issues, will report back on new numbers.

But on that note, here is the finished builds that have been reported on the forum or directly to me. I would take this as about maybe 10-20% of the total builds in the world at most.

Who's tuning it? I need to do the same. Paul recommended Kosmic to me, but I'm open to suggestions. Sorry to hijack the thread ;)

I will go with chuck and I will sell my fi and buy gtm sc beacuse if I reach 500 whp then maybe I asked for more loool

I am going to Kozmzic, was a 1 month wait, they are backed up right now.
There is another 370z being finished up there (370z 7AT with GTM stage 1 TT) which will get tuned here in a week or so. They are waiting on some new piping from GTM to finish the install.

Also having a set of TP put on, use to run LTH but got tired of the drone on a DD but have been blowing up stock cats and figure it is time to just put TP for now. Don't want the cats to blow and suck back into the engine block.

Thisssssss is the end result of almost every stillen kit owner.

Cool. I was waiting for it to get a little cooler before I took it to them anyway, so that works. Hijack over.

Melt-down imminent...

.. I prefer to emailing him beacuse I live in the middle east

I didn't say it would be reliable :rofl2:

Then you may have to wait. Email is iffy with GTM. They've answered the phone every time I've called, but email may take a long time. If I were you, I'd just stay up late/get up early and give them a call.

Only one car with stillen sc reach a 500 whp .. ur thread help me to be sure to sell my kit and going with gtm sc

Swiss370 also has 98 octane rating and some Vortech parts.

I will call him after selling my kit . . or maybe getting aboard to amrica and speak with him personally:tiphat:

500WHP on Stillen wont happen :/, I tired a few others tried, Closest we got was 473WHP , not me I was only 457WHP. @12SPI and all suppoting mods,

You should get to 500whp if you run 100 octane, upgrade impeller and pulley and push 11 to 12psi with bigger injectors and fuel pump.

The limiting factor will be the cooling of the system at that level of HP. Every boosted car has to deal with this though.

????
I'll pick 1 of them n say wrong. Limiting factor would be the 100 octane. That's not readily available at any pump. 100 octane for barely making 500hp??? :icon14:

We've said this many time to those who are new to forced induction on a normally aspirated motor, which is do lots of reading around here and researching.

It's easy to desire more power and buy stuff on impulse hoping to make this much power, but there's more to buying stuff and bolting it on.

Please start by reading the sticky threads:
http://www.the370z.com/forced-induct...ion-noobs.html
http://www.the370z.com/forced-induct...ion-noobs.html

The finished builds give you an idea of what kit was used, and the power made after tuning:
http://www.the370z.com/forced-induct...ed-builds.html

This should give you a ballpark.

No way would you see 40-50 WHP just from 100OCT, I had bigger injectors ,pump, heat exchanger ,Impeller and was at 12PSI 457WHP 93OCT, 500WHP will take 14PSI or higher and then your in built motor territory for sure.
Trust me man I was down this road..

I never said that it was practical. There is one station about 20 miles from me that has 100 octane for $7/gal ouch.

Definitely not Stillen if you know you want room to grow and no emission concerns.

ANQVM, why didn't u tune at 100 octane? I think you could get 40whp from it. How did the guy from Switzerland get to 500? I think he is running high octane or has a friendly Dyno.

What's disappointing about the Stillen kit is the torque # great on slowing down transmission wear and tires.

Dynapack, they read stupid high.
And I believe he is going of HP, not WHP.

Hey Guys

That is correct

We produce here in Switzerland with 100 octane, 500 HP (not WHP)
with 8,7 --> 9 PSI boost

200 HP more than stock

Greetings
Ivo

....at the crank....translates to approximately 390 to 410 whp

I believe MrSqueeze had a Stillen kit and was close to the numbers you are looking for, but in the end I recall it didn't turn out too well. I have a GTM Stage 1.5 kit on my HR G35 that will fit on a 370z or G37 with very little modification I will be selling it soon to make room for a GTM MHI TT kit. PM me for details if interested.
