Ok so this winter i plan to finally build the head in my car, upgrade turbo, change turbo manifold, possibly upgrade injectors. Head plans i am undecided on weather to go with the bisi stage 3.8 or his level x for cam, going with bisi springs and retainers as well, pro port polish and as much as i can on the head,(money depending,lol) for the turbo i have a buddy who has a brand new garret t4 60-1 70 cold side 84 hot divided housing, he purchased from full race, never got to finishing his car and could get hell of a deal, is it to big though? plan to switch from the ramhorn style manifold i have now which is for t3 and going to a forward mount custom manifold, which i i would assume i want to be divided some how for that turbo, just looking for some good input, hoping for around 500whp

 

thats a bit excessive for only 500whp, keep the ramhorn and get a different turbo. build the head and make some power. major head work will be needed but you have no need for all the parts listed to make 500whp. ive seen it done on a fairly stock motor and vitaras lol


who does your tuning? sticker guy? I see your from NH

im doing a z6/y8 build right now to run 11.50 index races next season, 350-400whp is more than enough for what I want. what do you plan on running with car car? from the sound sof it with a forward mount turbo its a race car

 

347whp 300;bs tq stock head, stock sleeves, eagle vitaras now, 880 inj, 50 57 63 maxed at 25 psi

 

do some head/block work and keep the turbo set-up and you can do 500hp easy

 

i had a t3 60-1 on a gsr and it spooled at 5300...i think thats too laggy for a single especialy in t4..but you can get a valvejob and valvetrain from bisi and his cam...and save the money from the port and polish and get a nice t3 turbo...

 

i made 480 whp on a stock y8 head (had valve spings tho) with a 50 trim,on vitaras/fjt.was good for 10.583 @ 137.00.

get the bisi 3.6 cam.there is a good write up on it in super street mag.

yeah i read the write up about it in super street, that's partially why i am asking, so consensus is that turbos gonna be to big? 5 is about when i see full boost anyways, i;m not to concerned about turbo lag either,
