Rb20 Turbo Onto R32 Rb25de

[adoboy666]

hey guys i have an r32 with a rb25de motor and i have a spare rb20det turbo

was wondering how the turbo would cope with the rb25de motor?

im guessing it would be spooling up alot faster compared to a rb25 turbo

im not looking at running much boost as i want to keep my motor alive, ive heard when u turbo a non-turbo motor the most boost u should run is 8-9psi

depending how the turbo goes i might run half that as wouldnt running the smaller turbo on a bigger motor hurt the turbo?? or would it just max out earlier, im guessing i would have lots of low down torque when the turbo spools up then it would probs max out buy 4000rpm

any turbo experts like to shed some light on this??

Honestly its not worth the time.

considering you can BUY a RB25 turbo for less than $350...

thats true but anyone done this before?

how did the turbo cope?

ive asked the same question before. if you check out the rb30 dyno thread, there is someone who ran a rb20 turbo.

i would think there would be problems with the internal gate flowing enough?
