looms are different, as are ancillaries and sensors. For example the injectors and PTU all need to be rewired. You'd be better off sourcing a second RB25DET.

he said it would be better getting another RB25

as in, its not worth bothing with an RB20

Personally, i think by the time you get the RB20 running properly you would have spent nearly enough for another 25. You already have everything on the 25, just get another RB25 block (and head if its not in good condition) and swap it. Thats the most cost effective alternative. Dont downgrade man, never take a step back i say.

Yeah that's what I meant, an RB20DET is like $1200 and an RB25DET is like $2200 these days. By the time you're done f**kin around with the wiring and the parts to fit the RB20 your $1000 saving will have dissapeared, so you're better off just buying a bare RB25 (as you should have the throttle body and manifolds already) and simply dropping it in.

If there's no engine in the R33 right now then put the 1JZ in there... just for shits n giggles

nah the r33 is non turbo.. well at the moment anyways

what about if i put a rb25de in it, the wiring loom appears to be the same visually.. could i put a rb25de in n bolt on all my turbo gear??

thanks
