2.3L N/A Budget Rebuild!

OK, my 1990 2.3L N/A has the oil screen clogged problem. The motor has over 200,000 miles on it, and probably needs a little loving. I want to keep it naturally aspirated, keep it as cheap as possible, and rebuild the motor.

I have a 5.0L, and I see full rebuild kits go for those at Summit for less than $300. I couldn't find any 2.3L rebuild kits there.

How much would a 2.3L rebuild kit cost? I'd be doing all labor myself. Who sells N/A (I'm talking cast pistons etc) rebuild kits?

Nah on the performance build-up. My 95 GT is my "go-fast" car:
