Hi
Guys some may know that I am currently building an engine that will be going into my R33 GTS the specs are:
RB30 Bottom End (Rated at 1200HP)
it is getting the whole treatment
Forged Pistons
Custom Rods
Rods Bolts
Clevite Bearings
Main and Head studs
balanced to 8000rpm
Oil restirctors
What i am confused about deciding on is two things CR (compession ratio) and head work ie porting, cams etc etc.
The turbo i will be using is a HKS T51R SPL (non ball bearing) my power targets are 800HP at the engine on Optimax and if possible 1000HP at the engine on race fuel. Please bare in mind the engine will be in a street car using a custom built auto i aim to drive it on the street with a detune state say 600-650HP. THe reason of the power targets are that when it does hit the track I want to know the engine can take it and run the numbers. So i need to know if
1) Will a CR of 8.5:1 with a Apexi Power FC PRO or Autronic SMC and the T51R allow 800 on pump fuel and 1000 on race ful?
2) What head works ie cams, springs, retainer and port work will be required to flow this HP also I do want it to be reasonably tractbale hence the relatively high CR
3) Which engine managment, ignitions system would people recommned, the fuel system will consist of a lift pump (33 GTR) and two main feed pumps (Bosch 044) and 1000ccc Rochestor Injectors.
Any input would be greatly appreciated I know this is a big ask but I want this to remain streetable when detuned to 600-650 for the street when the 800-1000 comes in for the quater I dont mind as the transmission is a drag box designed for limited rpm power band.
Regards,
Jordan
