A fuel pressure regulator will do nothing on a car with fuel injection, it's all a big gimmick! If you do somehow manage to get more fuel into the engine, all it will do is make it run rich, thus lowering the performance anyway.
Cams sound like a good idea, while it's all apart you could stick some bigger valves in and get the ports opened up a bit!
Yeah i read that a lot of people love the fuel regulator, and a lot swear its pointless....can never get straight answer on the net lol.
I have seen and read people using the ST170 inlet to help increase the air flow and throttle response, and from what ive seen it does make a difference, especailly when used with a upgraded exhaust manifold like i have.
The cams i can get are from a friend who work at Ginetta Racing in Leeds and he can get me cams and set it all up for me including shimming for bout £350, that combined with my exhaust manifold and if i do something to increase the air flow into the engine, after the remap i think it would be pretty good.
If just hard to figure out exactly the best way to spend my money on getting the best for the money, if that makes sence lol.
