Garrett 2860 -7's Or -5's? R32 Gtr

[R32.GTR]

hey guys,

i want to upgrade to bigger turbos on my 1992 R32 GTR.

i have decided on either Garrett 2860-5 or 2860-7, but not sure which will suit my car best.

given the fact that this is my daily car i still want it reasonbly responsive (no major lag) but am lookin for around 300-330awkw

it currently had 260rwkw with standard turbos.. until they blew

the mods are as follows:

Standard engine (as far as i know)

R34 GT-R Injectors

HKS pods

Standard dump pipes

Blitz stainless steel front pipes

HKS cat back

Hi-Flow cat

Adjustable cam gears

Power FC

Standard intercooler

PWR radiator

Exedy H/D clutch

obviously i will need larger fuel injectors and fuel pump, which i will be installing soon.

is there anything else i will need to upgrade to achieve 300-330awkw? will -7s make this sort or power? if so at what psi?

also could you let me know what turbos you run? and what RPM they start to spool up and peak at?

thanks.

Please use the search function.

There is a 10+ page thread on -9s vs -5s (the two turbos you are talking about).

All the info is cleraly spelled out, the for/against and so on.

Thanks.
