ok ive got a stock gsr motor w/160k on it. im gonna start piecing together my own turbo kit. i want it to be reliable with the stock internals for now.lookin for about 225-250whp

i can get a turbonetics p-trim .81ar t4 turbo for a pretty good price ($500), but i question how well this big ol turbo will work with low boost settings due to stock internals, also what kinda power i can expect of a good tune.

any help or suggestions would be appreciated.....also what injectors would be best

 

thats way too big of a turbo. at what low boost you would have to run it, it wouldnt be worth the time to install, try and find yourself a t3 of sort like a 48/49

 

I agree try .81 ar is to big for a 1.8 motor. try a 14b

 

sorry about the fucked up post

 

even a 14b is small at the very least go with a t3 .48/.60 or a t3/t4 hybrid

 

If she were a little fresher, you could shoot for 300-350whp reliably.

You mean .84 AR, and unless you are constructing a split turbine manifold that's a bit too big.

.58 AR turbine housing will set you back $150 or less on hookup from a retail outlet... it occurs to me that Trav-*** has a spare on-center .58 AR P-trim turbine that's never been used he'd probably let go... and should have you spooling by 3500-3800, 3 psi by 4000-4200 and then the boost gauge's needle *flies*, with a large volume merge collector manifold.

I've seen 1.9 liter GSR spool a 62-1/T4 with P-trim .84 AR by 4500 rpms, but it was a lag lag lag spin spin spin machine.

 

I say try it. From now on, I reccomend everyone slap the biggest turbo's they can find on their cars, run without a wastegate and just let build as much boost as it can at the redline.

 

ok thanks to everyone but ichbimsobose, if you think i am ------- stupid you are wrong. i could easily use this turbo when i build my motor this summer which is why i wanted to get it now and save some of the hassle later, but thanks for your smart *** reply, it helped immensly.

i dont wanna go with a 14b, yeah itd spool quick, but ive never liked those on b series, gsr especially. id much rather go with a t3 .48/.60 or a t3/t4 hybrid as someone mentioned. i guess ill look around and see what i can find

on a side note, how much whp are dsm 450's good for?

 

I dont think you're stupid. I told you to run the ------- turbo. Thats advice, take it or leave it. Eveyone told me not to run my turbo, and it came out perfect...soooo I think people sometimes overestimate lag.Go hug your boyfriend.

 

good one....cuz im so homosexual and all. you know, calling people gay stopped being cool in 1999, or atleast after you got out of highschool...*shruggs* thanks for the advice.
