Hi,
Well I've been searching this forum couple of weeks now, looking for answers to all of my questions, but havent really found solid answers on them. So maybe this thread will help out a bit. Ive been tuning and building my RX7 over the past 3 years, and am now looking for a skyline in the near future. So I understand a fair bit about tuning cars, and whats needed.
One of the questions I'm after is the following:
How much horsepower/torque can the stock engine/gearbox/driveline take? What I found was in the region of 500HP, however Ive also found threads saying 650+ on the stock engine and driveline. Anybody has a solid answer to this. I understand that tuning plays a key role.
When I would be after 750-800Hp, I would expect to change almost all parts in the engine, rods, pistons, valves, fuel management, etc. But is it also necesarry to change the gearbox? What horsepower and torque will it handle?
What about the stock crank, Ive read alot about it being able to hold 7500rpm, but would it also hold more than 500HP, or does it need to be changed also?
What Im curious about is the engine management, what are you guys running, Im now running a microtech on my rx7, and it seems to be a completely different league, compared to the skyline. Which are mostly running Power FC's or HKS Fcons.
Hope this doesnt sound to nooby, but I havent found any decent info on this. And dont want to be the guinea pig on this one. Ive found out too many things the hard way with my rx.
Cheers
Rogier
