Sup,I just got a 90 Si motor. Im planning on rebuilding it but I just wanna know what I should replace. Things like oil pump, water pump, timing belt, etc. The motor gots like 160k miles on it. Any suggestions would be helpful.

 

Bearings, clutch, all gaskets, resurface flywheel, new clutch, thats a start.

 

dont forget piston rings, oil pump, water pump, timing belt.

check the valvetrain as well

 

im planning on going all motor but not too extreme. i want to make the motor run strong as possible. do you know any websites where i can find parts for a d16a6? thanks for the help.

 

don't forget new rod bolts...this is a weak area for those motors.

I got my gaskets, rings, bearings, etc from http://www.importperformanceparts.net

They list a rebuilt oil pump on their site that's the best price I could find, but the water pump was way cheaper at my local auto parts store. When I tried to order the oil pump, they said they no longer carry them, only the new ones. I ended up rebuilding my own.

If your replacing the pistons, get some for a D16A1 (89 teg) - higher compression.
