it will be safe after you do the head work, sure, and maybe rebuild the engine while you're at it. you can never be too careful

Compression is one thing...compression ratio is another...compression is about 95-100PSI for the DX/LX and about 108-112 for the EX's..

11.5:1 compression will be about as high as you can go on pump gas fo a daily driver without any relaibility issues..

Wouldn't you only want one NOS...havin multiple Nitrous Oxide Systems in a car is pretty redundant....

1 NOS...big shot [IMG]i/expressions/face-icon-small-smile.gif[/IMG]
