mine was never stock in the first place, tahts why i consider the rb 20 conversion.
it had been bastardised about 20 years+ ago, and it was too far gone to take it back to orginal( guards hade been chopped and modifeied, floor pan modded, no origal fuel system and other things to many to mention), it was a shame to do it to it, but it was better than stripping it down and parting it out, i have a couple of orginals so, this is my daily street car with some serios mods......
so i clean up the body the best i could, did some interior and exterior work ( you should have seen wot i started with , www.acrdomain.com/memberpage/547037) and made the body look the best i could with a new coat of paint.
the guys from the prince club recon i have done a pretty good job with her.
now s for the other question, an rb25 or even 26 was too expensive for this mod and would have twisted up the body i recon, where a rb20, there are plenty of and plenty of bolt ons if i decide the grunt isnt enough for me.......
but any way im happy with it and asying thats i guess thats all that matters.....
