Hi Guys,
Im building my engine and i was wondering if anyone has built an RB26/30 engine using a CR of 9 or close to 9?
My engine mods are:
Top End
--------
RB26 Head fully serviced and mildly ported
HKS 272 Step 1 Cams
HKS Cam Gears
Bottom End (fresh rebuild)
-----------
RB30 Bottom End
Forged H-Beam Rods
Forged Pistons
O-Ringed Block
ACL Race Series Bearings
Oil Pump Drive Collar
R33 GTR Oil Pump
Oil Restrictors for the Head
Fully Balanced
Intake/Exhaust
------
Garrett T04Z 1.00 Rear
6Boost Manifold
XTR 55mm Wastegate
600x300x100 Tube/Fin Intercooler
ARC Air Box
3.5" Exhaust System
Fuel System
-----------
Bosch 044 Fuel Pump
700cc Injectors
Nismo Fuel Reg (Adj)
ECU
----
Apexi Power FC
Q45 Air Flow Meter
The reason i ask this question is if i can run a CR of as close to 9.0:1 as possible i hopefully can make my target power of 400kw at all four wheels with only using 16psi on pump fuel.This is going into an R32 GTR
I appreciate that this is very dependant on how good the tuner is, i will be using a very reputable tuner who has good experience with tunning GTR's
