alright i dont really know how much of a difference this will make but i have an turbo ls vtec with itr cams and gsr pistons. 10:1 compression ratio, i guess a poor mans gsr. anyways,. i have a b16 tb on right now and i was thinking that i might see a noticable difference since i have the cams and 2.5" ic piping. now should i upgrade to a larger tb now or what would be the optimum size? 58mm seems kinda small. i have a gsr 60mm tb but the throttle rotor is all upside down...can i somehow switch the rotors.

brief setup...

t3/t4 60 trim, .60 a/r
lsvtec
b16 head
itr cams
9lb flywheel
stage 2 clutch
aebs intake manifold. i think its ported to 65mm?
3" turbo inlet
2.5" piping with intercooler
3" downpipe (open)

tial wastegate - 7psi

hoping for 250whp tuned crome

For $300 that you will spend on a TB. Your not going to see some outrageous gain for the 58mm to the 60mm. But with the 62mm you may see about 7-10hp.

 

i thought the b16a/gsr TB's were 60mm? i could be wrong tho

 

if its 7-10 then ill get a type r. it wont cost 300.

 

Just get a max more to 64mm so you match the TB to your IC piping, really wont make that much of a difference, but it is only $100.

Not only that, but I've seen him post that he will modify the gsr TB to work for $20 or so. its maxbore.com
