Sorry about another BUILD post, Ive been reading as much as I can over the last 2 months while the engine was pulled and opened
and I just couldnt rap my head around the cams (lift/ect and how all that worked) so since I had to ask about cams, might as wall spill all.
I have $10000US to spend on parts (labour is covered) and want to spend it all on the engine at this time since its out.
The car is an 1989 R32 GT-R
Presently, all I have for mods are Apexi Air, 4inch exhaust and R34 Getrag 6speed (dont ask, dont know, it was bought this way)
I'm not a big HP freak, but since im changing the stock turbos and strengthing the internals I might as well get as much out of it as I can, WHILE sticking to a bolt on Turbo.
I prefer track/street driving, not so much drag. And prefrer as quick a response from the turbos as possible.
This is what was recomended by Skyline Parts seller in Canada
Turbos: 2860 -5 (aprox$2300US) , although I think I'd prefer GT-2530 or GT-SS or even the 2869 -7
(my head hurts from reading all the chatter, can anyone say which puts out the most HP and which has the best response?
cause from the turbo dyno posts, the numbers were all over the place, and the only common opinion was stay away from the GT-RS)
Pistons: Weisco (aprox$1100US) is there an equivalent priced part that is better?
Rods: Carrillo super a beam (aprox$1400US) again, is there an equivalent priced part that is better? or do I even need rods?
Head will be ported/polished
***Need Cams***
I have NO idea what specs are best or matter or even represent (and I assume springs/valves/retainers)
This by far is where Im lost and need help the most
Need Adj Cam Gears (is there really any difference?)
Is there (of course there is) an opinion on Head Gaskets?
Oil pump, He says N1 is fine upto 500bhp, or should I upgrade to JUN? Already bought the collar to strengthen the crank
N1 Water pump
Is there anything else internally or bolted on that would be best changed now while the egine is out???
Dump pipe? im guessing the pipes from the turbos? any particular brand?
Head bolts? are stonger ones really worth the cash?
Outside of the engine..
Wideband? PLX R-500, I dont mind spending the money as from what I have read it really helps with the tune and therefor engine life, am I corect on this?
And Since Im in Canada, whats a good clutch (remeber R34tranny) since It woudl be hard for me to go through JIM BERRY!!!!
I don't mind a twin, I just want something that will last a good amount of punishment.
I not asking for a ton of opinions (except on cams)
a simple BUY THIS! on the rest of my questions will help
thanks for any info!
