Its a pretty open ended and ambiguous question.

Personally, if i was you, i'd scrap the idea of fucking with the block and stick on a decent set of extractors and exhaust. That'd net you another 20-30hp and then i'd leave it at that. The price required to get more ponies out of an NA car isn't justifiable, especially if you are just driving it street.

If you are _serious_ about building hp. Buy a GTE.

Well The #5 Cylinder got scored when my rod broke so its already been bored out. Its actually almost back together.


How is it open ended? I said whats the stock hp of a 7mge and what hp increase will .020 do... I dont see how that is open ended. If its going to take me down 2hp I would like to know why.

An exhaust on a NA is not going to net 20hp. .020 overbore is not going to make any noticable difference in power. It will probably feel faster due to the old motor being old and worn out.

With that big of an exhaust on a N/A you are actually not going to gain anything. That exhaust is for a turbo car and lets it breath a lot more. The exhaust you need for yours to notice anything is something way smaller. I bought a HKS Dragger for mine when it was still a N/A and it felt like it lost power and also would backfire on a high rev shift. Now with the 1JZ it fits right because turbo cars need to flow freely and let out a lot of exhaust because of the added air going in. Think of it this way when you think of horsepower, More air in more air out = More horsepower. Even putting a cone filter on your N/A you are still limited by the size of the intake runners and are not gaining much more air in than you were without it.
