Garrett 2860r-5 Or 2860r-7

[gtr fan]

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.

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.

Are covered to the greatest lengths it's getting a bit silly now to have these questions still popping up.

Thanks
