Is it too much to expect the Greddy turbo to be able to put me to 300 whp? I know that stock turbod it's around 240 and with a full exhaust around 270? Can the boost be upped a bit Safely but without rebuilding with stronger internals...Right now I have a Lightweight Pulley so I think I'm probably at around 150 hp to the wheels, maybe 1 or 2 less...

Or should I just go ZPI if I plan on going to about 300? I don't plan on going any higher though because this is my daily driver.

300whp is easily obtainable with the Greddy kit. Depending on what dyno you get on. The guy with 271whp on a Dyno Dynamics is very close to 300+whp on a Dynojet.. at only 10-11psi. :D

There's still more you can do after the exhaust too. Meth injection, turbo cams, pulleys, Lightened flywheel (Frees up HP).

And how long could I run at 10-11 PSI before causing significant problems with my car? Assuming that I don't drive into the ground, but I do the occasional redline. Obviously that's a pretty vague question but is it reasonable to assume that my car would last say 80k without me having to replace things that normally wouldn't need replacing

The tC has been shown to handle over 300whp with an impecable tune. Tuning is key.

hehe, you should make that your catch phrase... put it in your signature, you must be sick of typing it by now!

rodlandscion

ok cool thanks for the info. And one other quick question...as I don't want to make another pointless thread. Why is the Turbonetics kit so much more expensive than the Greddy kit w/ management? The only things I noticed are the bigger turbo and intercooler, yet the make around the same whp...

Greddy is made overseas. They can produce more kits and sell them for less.

rodlandscion

but the quality is still there correct?

Greddy is one of the biggest and most trusted aftermarket companies in existence along with HKS. I knew about them even before i got into tuning. Since its official introduction , it has easily become the fastest selling turbo kit for the scion tc

Absolutely, wait till you recieve the kit and you will know. Its a beautiful and nice running kit.

Internals and PnP head would help a lot too.



I heard that lighter pulleys are not safe to run them in turbo cars?

Is this true?

noTCed

I love my greddy kit and will be taking it to the dyno the 14th to get it tuned up to 10 psi i have a catback exhaust and lightweight flywheel i will let you know what the numbers end up at

rodlandscion

Nice very cool. Well Greddy it is then...if all goes well, we are going to start carrying them at our dealership, and I'll be buying the first one haha

SkaTG2k3

wow... that is a pretty cool dealership... you guys will install the turbos in house? if so, what is your service manager going to do in an engine failure claim from a greddy turbo tc? fix it free?

rodlandscion

Well I'm not sure if we're going to do installs here. It's all kind of up in the air until I really sit down and talk to them about that very thing. Not sure how we'd go about warrantying something like that.

Stock pulley is fine... Save for a Flywheel when you change your clutch. It will be needed with turbo applications...TQ kills clutches fast.

tikbhoy

it can be bias depending on who you ask, the whole aftermarket pulley has been a big debate. its just a can of worms if u ask me

Revilo

it sound good (the flywheel) but it would produce the same amount of hp?
