Tuning a Turbo II Rx-7
I was wondering the modifications needed to acheive 250-260 rwhp at under 10lbs of boost in an S4 Turbo II, The reason why i started this thread is I plan on dropping 7grand into modifying my car, which includes rebuilding the engine, So basically im looking for the cheapest/safest way to acheive that much power.
|
is the car completely stock? good compression? any particular reason you want a max of 10psi?
|
If you check my set up i make @295 rwhp at that boost.
|
Well the compression should be up to par if i'm getting a rebuild, possibly with a turbo 4 port, I already have Greddy Profec spec B, Apexi Turbo Timer, 720 cc Injectors all arround and an Fcd

rtek 2.0 $400
750cc, 1000cc RC eng injectors $400 walbro 255 fuel pump $100 RB 3" exhaust $850 intake $100 ebay fmic, piping, etc $500 total: $2350 on this setup, my stock-ported S4 TII dyno'd 250whp@9psi max on a dynomite dyno (numbers similar to mustang dyno) |
Come talk to me. I'll help ya out.
