LanceM Posted October 19, 2003 Share #2 Posted October 19, 2003 It will fit, how long the engine last with 10+ compression ratio is the question! Link to comment Share on other sites More sharing options...
echocluster Posted October 19, 2003 Author Share #3 Posted October 19, 2003 does anyone have a idea, how long it would last? Link to comment Share on other sites More sharing options...
2ManyZs Posted October 19, 2003 Share #4 Posted October 19, 2003 If you have a turbo engine, you won't have to worry about the compression. The turbo engines have dished pistons and the compression will probably be more in the neighborhood of 9:1 with an E-31. No problems.According to the engine calculator, your compression should come in somewhere between 8-8.75:1 depending on which head gasket you use.

LanceM Posted October 19, 2003 Share #6 Posted October 19, 2003 I'm not much of a turbo guy, but they but everything I've read says that they tend to run very low compression compaired to NA cars. I would think that once the boost comes on you wouldn't get around the block... Link to comment Share on other sites More sharing options...

2ManyZs Posted October 19, 2003 Share #9 Posted October 19, 2003 Before you get too excited, which head is on the Turbo? The P90? The P-90 is already one of the best flowing heads due to it's being used with the Turbo, so if you are keeping th FI and Turbo, the E-31 won't help you much, if at all. Plus, with the Turbo, you're gonna run into trouble with detonation at 9:1 more than likely. 9:1 is right on the borderline with a Turbo. Which means even more work and money. You might be better off to spend your money on an intercooler. Link to comment Share on other sites More sharing options...
LanceM Posted October 19, 2003 Share #10 Posted October 19, 2003 The E-31 is an early 240Z head, NA and will produce probably the highest compression ratios available using a stock head.Around the block, Hmmmmm, pull it out of the driveway, kick it in the A$$ and call a tow truck to get home....

echocluster Posted October 19, 2003 Author Share #11 Posted October 19, 2003 ok thats good to know. i think that it has the original head on it. and i am keeping the fi and turbo. Link to comment Share on other sites More sharing options...
echocluster Posted October 19, 2003 Author Share #12 Posted October 19, 2003 i thought you ment the engine block. i was thinking the compression could not get around the block or something... i was trying to figure what the heck you were trying say Link to comment Share on other sites More sharing options...
