I have a 97 ST Celica, which has the 1.8 7AFE engine.
I'm looking for advice from person(s) who have attempted to nos their 7AFE. I know I must upgrade my exhaust and intake as a bare minimum, but I want to go a step further in strengthening this weak block. I'm looking to replace the pistons and rings with better ones and maybe the header as well. I've read multiple articles on the 7A-GE conversion for the header, and I have mixed feelings about it. If anyone has personally tried to replace pistons, rods, rings, and/or the header let me know and give me your advice. I want to be able to shoot more than a 50 shot, hence the replacement of the mentioned parts. My last question is, if I replace my pistons, do I want a higher cr or a lower cr for NOS? I know for turbos, the lower you go, the better due to the characteristics of the turbo... however, I'm not too fimilar with NOS and what conditions are optimum for it. If anyone can help me out, I'd really appreciate it. Oh, and NO, im not swapping engines, so don't bother telling me to do so. The 7AFE is fine for what I want to do. Experienced Advice only please. |

Quoted from another post I made, cause I'm lazy. Don't replace a perfectly good headgasket. 7AFE head gaskets have a metal component to them, and should be pretty durable if the engine is not run hot, or otherwise abused (too much spray). Also, without modifying a 4AG head gasket, I don't think you will find a true performance head gasket for a 7AFE outside of having a copper one custom-cut, and that's a totally different subject. |
