Car: 1991 GTA, 1992 TA Convert Engine: 5.7 TPI Transmission: Auto Axle/Gears: 3.27 | Anyone use the First Fuel Injection Manifold?
| I looked all over this site for info on this question and could not find any references. I have a 1992 TA Vert that was restored, and then we had an engine fire while my wife was driving the car. The car was saved, but the engine compartment looks like charcoal. The cause of the fire turned out to be a failed adjustable fuel regulator that was replaced 4 years ago. The diaphragm broke, gas went through the vacuum hose which disintegrated, and then it sprayed on the engine and then a fire. Watch out for this problem. I have become aware of similar circumstances. My next restoration will have a fire suppression system. This car was restored to original condition mainly because of Pontiac purists out there. I don't care any more about that. The car is going to be repaired and I plan to make a cool performance convertible out of it. I may changes the color also. We are going to weld up some areas on the frame and add some bracing to strengthen it further. I am going to build my own 383 and have that planned out. I have the parts. I used to build race engines years ago. I also have a 1989 GTA which just won first place in its class at Autorama 2009 in Houston. I have a lot of experience with TPI systems and have three of them. I like the torque because it works well in a normal driving range. I also know that this engine will run out of breath, fast. So, finally to the question. I have been talking to First Performance http://www.firstfuelinjection.com/. They have a bigger TPI that will bolt on, flow a lot more air, and use the same computer system and wiring. They claim the engine may breath as high as 6200 RPM and you still have that low grunt torque. Has anyone done this? Oh yeah, I plan to put a T56 behind this engine and a better rear end. I already have most of the parts and a donor TA will all the wiring and parts. Sorry about the long post here. Thanks. dlynde. | | | |
