Hey all
i have a r32 gtst im about to pull down and paint. so while im at it will do work to the engine.
my pet hate is the gutless no torque rb20. was going to mod it but i dont think itll make up for the down low i like on the street. looking at roughly 300kws give or take
I then thought about putting a rb25 into it. i went out and got a rb25 turbo engine, which i have sitting in my shed at the mo, ready to be pulled down......
Then another idea struck. what about a 25/30? i know they wont fit under the bonnet as such but ill work around that.
Is it worth the hassle of a 25/30 over a 25 for modest street only car? I can get it regod with the 25 engine easily enough.
if i went the 25/30 route, if i got a series 2 rb30 block and 25 NA head would the head need to be modded to line up all the journals properly? etc?
is it right a 25 NA head all lines up with a 30 better and without modifying like a 25 turbo head will need to be?
Can i use a rb20 ecu and wiring with both engines? or will i have to rewire for either?
have a few more questions but will keep reading and update this thread as i need to
thanks
Adam
