Hey guys, I have a 1996 R33 skyline GTS-T, recently bought it and thinking of adding some more power, current mods to my knowledge are ;
- splitfire coil packs
- kls power spirit turbo
-fmic and intake (Z32 afm and all the rest)
-high flow cat and full exhaust system
-walbro 500hp fuel pump
-current spark plugs are platinum PFR7B (problem possibly)
-dump pipe
Etc etc etc, basically all the basics
Last tune was in 2013 and was 220kW, I've misplaced the paper though.
So here's my question, what could I do to possibly get it to 250kW, I was thinking cams or ?
Also, at high revs, around 5500-7000 the car starts to spit and misfire, but the plugs were changed in 2013 so I don't know what it could be. I'm aware there's topics on these but I couldn't really gather much from them.
Thanks for your help guys.
