Rb20 Upgrade

[jap32r]

Hi all this morning i went out to buy a rear strut brace for my 32 but i ended up coming home with an rb30 hi flow top mount chrome manifold a t3 turbo and external waste gate, to be honest i only bought these cause the price for the whole lot was less than hi flowing my standard turbo, got a few qusetions for anyone who has done the same or simular upgrades what sort of power/rwkw am i looking at i currently have a pod filter, turbo back 3'' exhaust, hi flow cat, fmic and mines chiped ecu, i will be getting a boost controller next and will finally be getting thew thing dyno tuned.

it really depends on the specs of the turbo and how much boost u are going to run.. anywhere from 180rwkw - 210rwkw if you are still using standard injectors...

but if the manifold is for a rb30 it wont fit your car!!!

ok thanks for that but we measured it up and it looked like it would fit?

if i get an rb20 manifold can i get an adaptor for the turbo and external waste gate?

yeah i have a tdo6 on my standard manifold, just had to put a spacer in there to get it to fit.. i have an external gate too. you need to get a pipe for the gate cast welded to run the external gate.. it is probably easier to get an aftermarket stainless manifold and moddify that.. i dunno depends whats available to you.

i am pritty sure the rb30 manifold is different as you pay $250 for them and about $50 for rb20/25.

sell the manifold on calaisturbo.com.au then buy a cheap ebay stainless manifold with an external gate pipe... you can get them for around $250 as well so you wont b loosing out..

you are going to have to do a bit to get it all to fit anyway. your dump/front pipe will probably need to be moddified as well as the intercooler pipes to get it all to fit and line up.

thanks for all your help. i will chase up a different manifold i might take this one back to the guy i bought it from cause he swears balck and blue that it fits i'll just get him to exchange it for an rb20 manifold.

thanks again i will post up dyno results once i get it all done.

RB30ET manifold WILL NOT fit RB20DET....you could always cut off the flanges and put RB20 ones on, but it probably would cost more than its worth
