Wuts up,
I been trying to upgrade my Redtop SR for a while now but cant make a decision because my budget keeps changing. So ive decided to go with a mild power upgrade so i dont have to spend $ beefing up the motor and buying trannies.
My question is, is it worth getting the .86 a/r over the .64 if im not going to upgrade cams or the IM? I know the .86 can flow more with those mods but since the engine is limited with the stock cams/IM am i really gonna see a substantial difference between them? Is it enough of a difference in exchange for the additional lag? Im thinking the two will produce similar power at similar boost since the .86 is hindered by the stock cams/IM inefficiencies. Just figured id get advice from those who have experience with both turbos.
Thanks for any feedback,
Laz:bigok:
