7A-FE Rebuild., Questions on rebuilding a 7A-FE. Options

[DeviousST]

I own a completly stock 94' Celica ST, with a ticking piston (at least that is the toyota master tech's opinion), that is engine threatening. Being the glutton for punishment that I am I have decided to rebuild and improve upon my base AT200 platform. I have all the aftermarket parts figured out, where to do the build, and the equipment to do the build, so here is my problem: How do I build a 7A-FE that will be reliable with about 7 pounds of boost. Do I just buy stock toyota pistons, connecting rods, and rings? (I want to stick with the original crank) And what about the heads. Will stronger valve springs with an otherwise stock valve train make my engine more resistant to boost and rpm? Internal Engine help would be greatly appreciated.

If your going to go through all the trouble of rebuilding the engine why not just drop a different one in? Perhaps look at getting a 4age?

Well I didnt quite feel brave enough to go beyond my base platform. I saw a complete engine at a local junkyard the other day sitting in an 89 corolla gts, and I was kinda wondering if that was a 4age, but they want $500 dollars for it all. It just seems cheaper in the long run to stick with 7A-FE. And I'm pretty damn cheap

for 500....complete? thats pretty cheap. Forged pistons run what ~$300? and forged rods are more than double that iirc
