Just requiring info on this build-up, wat is required to make them suit together and is it a good move, would i be expecting good performance.
Reason i ask this is because i can get them fairly cheap cheap, i've inspected them both, and there both in good order, no bad wear anywhere.
The Head is only an N/A Head, what is the difference between them and the turbo head.
Another thing, how do i prove it's an RB25 head and i don't have an RB20 Head
Cheers...
