Im rebuilding the motor in my car and I was wondering if anyone had any tips or any information of problems or anything I might run into. The car has the 2.3 liter Quad 4 H.O. Any info would be appreciated.

Yea, get a manual better than a Haynes. Have some alternate transportation available to make trips for specialty tools you'll need along the way.

What manual would you suggest that I get?

I have the Helm's set... very good documentation and diagrams. They were the ones written for GM and specific to each year. Very accurate and complete.

I think the sale price is over tho.

Do you have any info on performance upgrades and where the best place is to purchase aftermarket and oem parts?

i'm going to be rebuilding my quad within a month or two also... though i dont have the HO :(... just the regular dohc.

i dont know if i will add any performance too it though or not. i graduate next year and plan on moving on (getting a real job, moving away, getting a house, getting a new car, etc..). the GA will definetly be a good beater (pretty decked out beater nonetheless, lol)

Just for curiosity's sake, since Im gonna strip the block down anyway, how much of a power gain could I expect if I were to have the cylinders bored out? Does anyone know?

^^ probably not too much.

you should do that though. most (if not all) professional rebuilds replace the pistons with oversized pistons and bore out the cylinders (thats what i was told by a few shops that rebuild engines).

my motorcycle has bored cylinders and the original owner said you could feel the extra power... though on a bike, you can easily feel an extra 2 horsepower gain ;)

What manufacturers should I consider when purchasing oversized pistons?
