gtr fan Posted September 14, 2009 Share Posted September 14, 2009 I am looking to get sime new turbos for my GTR (Garrett 2860R-5 or 2860r-7). I am after 300awkw. Anyone know the big difference between these turbos? Which one would be best suited? Will 550cc (already installed in car) be sufficient to deliver enough fuel for the power I'm after? Any ideas what boost level I would need on these turbos for that power Thanks for any help.

bradsm87 Posted September 14, 2009 Share Posted September 14, 2009 (edited) I can't believe after all the info that's been getting round, people are still considering the -7 turbo's. -9 -9 -9 -9 -9 the -9 spools up about the same as -7 turbos the -9 makes more power than -7 turbos the -9 generate less heat than -7 turbos the -9 is a newer and better in every way version of the -7 that costs the same yep, the -9's will JUST do 300 with stock cams and about 19psi of boost or easy 300kw on 17psi with a set of 256 cams. Yep 550cc injectors will support 300 easy. the -5's will obviously do more but it'll be laggier and u'll max out ur injectors before U see the potential of the -5's.

R31Nismoid Posted September 14, 2009 Share Posted September 14, 2009 Please search. -9 -7 -5 Are covered to the greatest lengths it's getting a bit silly now to have these questions still popping up.
