My boy has a similar setup exept he has a stock head. Hes running an t3/SC61 and he put down 417whp and 340tq and ran a 12.9 at 114mph on pump gas and shitty *** street tires in a 95 coupe with AC and full interior. I think the SC61 is really nice on this setup and it pulls like a mother when it hits full boost. Ne ways if u want a tial BOV its gonna be a 50mm BOV and i think the tial 38mm or 40mm wastegate would be good for u. The walboro 255 fuel pump should do the job and injectors i would get maybe like 720cc or 780cc just so u have a little room for upgrade and itll be plenty for u if u want 350hp. Hope this might help u some.

 

yea it helps thanks alot anyone else ?

 

Depends on your goals........ In my experience, If your only going for 350 then you would want the best daily driving turbo you can get. I would go for something along the lines of a basic t3/t4 or sc34. That would get you the power you want and would have in my eyes the best overall driveabilty.

 

yea honestly im not worried about daily drivablity i mainly drive it on the weekends and pretty days... my goals are 350 plus lol

 

come one guys noone >?

 

well do you want something with quick spool or something that gives you a little lag so its easier when just driving around normal? Whats your price range?

 

Injectors: 550 will be just fine for 350whp. But I would get like 650-750's for room to spare.
Wastegate: A 40mm Tial will do.
BOV: Not sure
Fuel Pump: Walboro 255
Springs & Retainers: Definitely replace....Skunk 2, Crower, its up to you
Turbo: A T3/T4 would be plenty
Cams: I hear stock GSR cams are good, I have the skunk 2 turbo cams and like them. It's your choice.

I'm running 375whp on a T3/T4 .57 with 550cc's @ 78% duty cycle....click this link and scroll to the bottom. You can see dyno curves and a list of all the parts that are on the car..... http://www.cardomain.com/memberpage/785908

 

i want somethin with semi quick spool lets say between 4-5k full boost but will produce alot of power to get near my goal of 350+ i wanna spend around 700 for the turbo

 

with no cat and my 3" downpipe, I start spooling the T3/T4 .57 around 3200rpms. Hit full boost around 4000-4200.

 

t3/t4 57 trim would be good

 

I run a straight LS in my car with a built bottom end (8.7:1CR) and the head is stock with the exception of cams... I am running an SC61S with the .63 ar 4 bolt housing, and t350 stage 5 wheel... My car sees full boost (about 20psi) by 4600 rpm..... I love my SC61

this is what i am running. the sc34 will also be good. you shouldnt need any more turbo than these two to achieve your goals.

dont forget to get an aftermarket intake manifold, especially if u are doing cams so that they can breathe a lil better. i was too broke to go aftermarket so i fabbed a shorter runner b16 manifold to my ls.

you can do 350whp on 550's, but since you have a worked motor, im sure you will want more soon. its better to get the injectors a lil bigger now.

also i think the jrc intercoolers are only good for 350ish, and as i said before it might be a better idea to overplan now and give room to expand later

 

Sc34.. nice street turbo..

 

ive made my turbo selection of using a sc61 now i need to figure out the rest of the stuff... any other suggestions ?

 

new setup consists of a hint of vatack!!!
