As the post states I just picked up an 89 CRX Si. The only problem is that it has 260,000 on the motor. So my question is how much horse power is possible out of the stock motor (assuming I sleeve and upgrade all the parts). I was originally thinking putting a B16a in it and some nitrous. But if I could get 12's out of the stock motor with some nitrous then I would rather do that.

Please post some intelligent awnsers, and why you would think one way is better than the other. Or how I could get 12's without turbo. etc. thanks
