You need to modify it into a return-system to add an adjustable FPR. Means fuel tank to engine and back to the tank. In the return line you have to fit the FPR. ;)

I'm just learning about the electronics topic and I'm still in contact with Americans who tune up Supras, Skylines and such Supercars. I also asked about the S-AFC for my IS200. I got told that if you are going to tune your car per AFC and NOT on a dyno. You will need wide-band gauges and wide-band O2 sensors and such to make settings working perfect. Go there for a manual you can read: http://www.apexi-usa.com On N/A cars it would give you 2-4HP after installing an SAFC. <_<

Yeah! The Lexus IS200: 1G-FE 2.0L straight six (114KW) The Lexus IS300: 2JZ-GE 3.0L straight six (157KW) Toyota Altezza: 3S-GE 2.0L 4cyl. inline (154KW) If you want performance, try to get the 3S or the 2JZ.... a turbocharged 2JZ would give your IS an ultimative kick in the A.SS. Also the 3S.... with a turbo conversion it would be too easy to get 400-500HP out of those hell-machines. I wouldn't try to hit the 300HP area with the stock 1G-FE..... it could blow up. NG, RR
