hey guys

im new in these parts. ive got a question. i read at the skylinedownunder forums that the rb25 can be changed into an rb26 with some parts from parts from the rb26 put into the rb25. is this true? if so it would be cheaper just to get an rb25 and mod it with parts from the rb26? right? please help. thank you

I Think itd be much better idea just to buy a rb26.

i'm sure it can be done, but whether its worth it or not i'm not sure. I mean with all the work and money you'd need to put in to make the RB25 into an RB26 spec engine it would probably come close if not exceed the price of doing a straight rb26 conversion.

in my case, i live in america, i own a boring 240sx, dumbass KA engine. now gettin an rb26 is pointless, difference is .1 liters, twin turbo, gotta convert to single to make it an easy fit, rb25 is already single, and with the 26 i need the 25 tranny. so im gonna go with rb25.

can anyone elighten me about 26 parts goin on 25? i know heads can go, anybody know any others.
