For Those In The Know. Do I Have The Correct Bits?.

[rockabilly]

right guys, you lot have been superb, threads etc. i think i may have made an incorrect turbo choice here. you tell me..

my spec when i build it will be. rb30 bottom end, cp forgies,spool rods, n1 oil/water pump, tomei baffled sump, exedy twin plate clutch,720 inj, twin in-tank tomei fuel pumps feeding both ends of the rail, hks adj fuel reg, apexi d-jetro,1.2 tomei head set. arp head bolts,jun 264/272 9.7mm lift cams,tomei adj cam pulleys. the above i have. on its way is a extreme turbo kit from oz,(thanks leigh).

that consist of a cast tubular manifold, 44mm wastegate and a gt35r with a 1.06 rear. now my exhaust is 4" turbo back no cat.

i an after torque around 550lbs really, dont want to rev to high. will this set up do?. my current rb26 makes 620 bhp @ the fly but only 440lbs torque on 2530,s and the above parts. any advice guys is good.. do i need to go gt42 or t51r?. woild like 450 rwks, i think we use bhp so 650 bhp

@ the fly..cheers bernie uk.. rb30 in progress.

all there but you need to spend time with the cam timing. and about 1.8 bar boost should give you it. but the gt35 dont have the same turbo rush as a good ol t04. slightly less lag but when they come on its just not as exciting.

and in saying that i mean its got less torque with the same boost. id sugest getting a t04z with a .84 split ex housing. much better than a 35r. wich is a good 2-3 sizes smaller.

on my 2.6 its all on hard by 4500 (1.5bar) with good boost building from 3250. its got the good kick of a good strong turbo and isnt boring.

youl find it will have about the same responce as your current set up.
