I've had this car for almost 10 years now.... it's seen more abuse than the front of my favorite hammer. It's got 203K on it and has never been rebuilt. It's also a 9:1 compression stock 1G N/T 6 bolt engine, N/T cams and all. I have a ported 2g manifold/ported O2 with a ported 14B on it with 450's running at 55psi with a rewired 180LPH VR4 fuel pump, MAFT blow-thru, 350cc/min water/meth injection, Supra MKIV sidemount (a very beat one, it still has half it's fins though), 2.5" side exit exhaust, Keydiver stage 1 EEPROM. Tuned it with the MAFT, running 11.0:1 AFR. Base timing is retarded, set at 2deg BTDC. It's still not knocking, so I can proably add base timing and/or lean it out more. I can't add boost, the VR4 pump has a pressure relief valve that cuts fuel pressure off at 70psi. At 55psi base pressure I'm at 70psi under full boost (15psi). Need bigger injectors and fuel pump....
I just got a dyno so I figured I'd finally see how much power I could get out of this setup without spending more money on the car. I'm pretty much happy with where it's at. I don't have a ton of money to spend on it, and going any further is going to cost at least another grand... which I'd rather spend on a less rusty DSM.
Since I'm not knocking and my EGT's are ok I can probably lean it out more and lower the IDC a bit to prevent some of the high RPM roughness caused by the injectors running at 100%DC. It could really use a set of 660's or 750's and a walbro 255 pump... and something better than a MAFT to tune it with.
