Rb20det Vs Rb30e+t

[shakotan-cefiro]

ok as some of you might have read my engine is showing signs of stress

so as i know rb30's very well i have decided to build a 25/30det

using the na rb30e block and rb25de r32 head with no vct ......i can hear the booing already

but i have succesfully pulled lotsa power out of this set up and the low down torque is sooo good

now im going to start by swaping the rb20det for a r31 gts rb30e and turboing that with vl turbo parts

will my front facing rb20det plenum fit on the rb30e head?

will the exhaust manifold from my rb20det fit on the rb30e

in the past i have used vl turbo injectors but im wondering what would u guys suggest as they max out at around 200rwkw

i will use a dalkhalf (from r31club ) remapped ecu

i plan to run 12psi with the higher compression of 9.0:1 this should be suficient

when i hit 200rwkw i will put on the 25 head lowering comp to 8.5:1 and strengthen the bottom end

i know the rb30 is old and single cam but they are a great engine many people (rabjab) make huge power and retain the single cam for a while it will be rb30e+t

please comment all imput will be considered

thanks Ben
