I have just recently purchased a set of R33 N1 turbos and its propted me to move everything onto stage 2 tune.
At the moment i have the follwing ( engine tuning parts )-
Apexi PFC and Commander
HKS Priest exhaust
HKS front pipes
Decat
HKS plugs
Nismo FPR
Profec BII boost controller
HKS filters
Splitfire coil packs
I have just purchased the 33 N1 turbos and wondered what i now need for Stage 2-
my thoughts are-
Turbo elbow`s--but which ones to go for?
Injectors--what size and what make?
Fuel pump-Is a Walbro 255l ok to use?
Airflow meters-which ones with normal sized pipework?
Cams--Thinking of Tomei 260-252 or 260-260 both 9.15 lift--which suits the car better
Do i need an uprated head gasket running 1.2-1.3 bar
Do i need all of the above or can i delete items from the list.I will get an oilcooler as soon as possible. I dont have an uprated intercooler but do i need hard pipes for the intercooler at this level of tune..
Lastly what BHP/torque can i expect running above at 1.2-1.3 bar ( Fly, hub or wheel figures helpful but state when answering)
I know its allot of questions, if you cant answer them all then try and answer at least 1 to help me out.
Car is an R33 GTR, big brakes, coilover suspension etc, so should be ok with just engine mods for now..I dont do 1/4 mile or track days with the car. The clutch is a new genuine Nissan item covered 4000 miles from new but as i said the car doesnt get any hard use or launches.
