hey guys. Well i'm new to this evo scene and I'm builting an EVO for full time track car.
so now It come down to decide which turbo should i use, well i have been thinking about use GT3072R single scroll or GT3572R Twinscroll. And I have stoke kit on engine about 2.4L. So can you guy help me which turbo should i use ?
** it not for drag car **

 

Until now, I had never heard of the 3072, or the 3572 either, for that matter. Of course I am not really up to speed on the latest Garrett turbos.

 

wait its a full time track car but not a drag car?? so by track you mean like road courses or what?

 

well on turbo i think it the same as GT30R and GT35R

yes sir road course. sebring if you FL guy

 

you need to search

see what shops are running in their cars

 

So is your engine almost a 2.4 or smaller maybe i dont know what do you mean ?

 

hta 3076

 

did you max out the stocker yet?

 

Uhhh. . . yeah more info needed. . .

Who is doing the tuning?? That will play into what you should run . . .

If you REALLY have a 2.4L then a 35HTA with a high compression motor would be awesome on E85 . . .

 

if the tracks you run at are tight 30r

if they have long/highspeed straights 35r

I would look into some of the twinscroll options too

 

If, as you say, "full-time", dedicated, roadracing and large displacement then I wouldn't go any smaller than an HTA 35R. Don't waste your time with the 3076. I'd probably go HTA 86, or, PT&E 6262. On race gas this should get you smack into the mid, to high, 600 WHP range.

 

well on the motor. info
we use AMS crankshaft, oilver rod with wiseco 86mm, Ferrea valves (not sure if it over-size or not :P) and 286 cosworth camshaft, Full_Race exhaust manifold

HTA35R turbo isnt boost kinda come late ( 3500 - 4000 rpm ) ?
The tunner i'm not sure which yet ( gotta find the one that do this track stuff )
oh yeah I will keep the car under 500 whp tho.....( 450whp thats what i want) still newbie to track

so i'm kinda need you guy help decide on turbo, we kinda of look on 30r or 35r ( but the price on 35r only few bucks more )

 

later than that 4000-4500

 

those turbos will be too laggy, even on a 2.4L

 

Like Evolutionary says, it's the HTA 35 on a 2.4, although this will put him up over 600 WHP on racegas won't it?

Will you be running race gas and a standalone, OP? What class will you be running in?
