hey guys i just bought a greddy turbo kit recently and was wondering what is the full potential i could get out of my ap1 S2k and this greddy turbo kit ???? I know that it leads a 60hp gain and abt 300 with a stock S, but apparently the t518z could hold up to an approximate 420 hp??? what do u guys think the perfect setup would be to gain atleast min 350hp??? Sorry to sound like a noob if i am im only 19 and this is my first car so yeahh could anyone help me out??


- inline pro intake manifold
-js racing throttle body
- aem ems
- koyo radiator
- js racing thermostat
- js fan switch
-js racing test pipe
- spoon radiator cap
- hks hi power dual exhaust
- greddy boost controller
- greddy turbo timer
- dyno/tune

 

if u want more then what the greddy can do.. u should go with another kit.. or do the pfab replacement manifold with a gt3071r in the t25 housing and internal wastegate with the greddy kit

 

Nothing in your list of mods is going to net you any real horsepower with the kit since the kit is basically maxed out from the factory. Sell it and get a larger turbo kit if you want 300+ hp.

 

you will make in the High 275ish to low 300's. you will need injectors for sure. Bigger turbo.. A inline pro manifold is good -- top out 600hp. but its great for what your doing. Im running a 6265 turbo on the inline pro manifold. Putting down 360hp at the wheels but maxed out my rc 650cc injectors. Go with ID 1000's injectors for sure. Its all about the tune for sure!!!! I wen t to 1 tuner and only got 300hp. Went the very next day to another and got 360hp.. soooooo ITS THE TUNER.

 

Keep in mind stock wheel horsepower will be around 200whp for that car. With the Greddy kit, you'll get close to 300 tuned. That's a 50% increase in power (or around 120 crank hp increase).

For your first car, that is gracious plenty to get you in serious trouble with the law.

 

Thats so true. If you already got the kit... Slap that thing in and go have it tuned. You will smile the whole way home for sure.

 

Don't need the J's fan switch or boost controller. You can use the AEM EMS to drive the fans and also control boost.

You don't really need a turbo timer. Just let it idle for a bit if you have run the car hard.

I don't think that HKS flows so well. I'd rather run the stock exhaust for free than the HKS. Ideally I'd run a single 70mm exhaust with the stock cat.

You shouldn't get the intake manifold or throttle body. You will not gain much power over using the stock components.

Your tuner will be the most important factor.

 

thanks for the advice and replies

 

read my new post, we just made 305.10whp on greddy's base tune with just the kit, greddy ti-c exhaust and a berk HFC

 

or the "dyno"...good numbers tho
