Building the 7afe to handle boost, Need some assistance Options

[rapid36]

Hey everyone, I own a 94 Celica ST with the 7afe motor in it. I have 4k to throw into this car and want to redo to handle boost and hopefully generate some great hp with it. I have basically every piece of parts i need gathered but still need a little help on some topics. Here are the parts I have so far:

1) 4age forged pistons still keeping it at 9.0:1.
2) forged 7afe H beam rods
3) stock crank
4) Bored out cyclinders
5) t2 turbo kit
6) aem piggy back
7) boost gauge
8) colder spark plugs
9) 440cc injectors
10) 12.1:1 FMU
11) 255 fuel pump
12) wide band o2 sensor and gauge

The thing ive been thinking about is, Do i need a different crank to handle the extra stress that i will be putting on this motor? some people online are saying its forged and the other half are saying its not forged. So does anyone know for sure which one it is??

I have no idea how much power i will be able to generate with this setup but it will be towed to the dyno shop as soon as the build is complete. Of course i wanna make sure everything is able to handle the boost ima be shoving into it. I have no idea on how much boost i will be able to run, hopefully 15psi or more depending on what the dyno people do. I have never turbod a 7afe before only did hyundai tiburons before this, but i did do tons of research on the 7afe, but still have some remaining questions.

Also does anyone know what else will be needed to do to sqeeze the most power out of this motor as i can? without doing a swap of any kind. Also it will be nice to know if anyone has a similar build and see what kind of numbers they are generating.

Thanks.

If your looking to get 300hp out of a 7a your looking at NEEDING forged rods, forged pistons, id go ahead and do a complete rebuild, a clutch that can handle 300 and hope your axles and trans still have life left in them, some porting work, probly going to have to do some oversized valves, cam grind, atleast a gt25 turbo, 550cc injectors, 255 fuel pump, and something to tune. If you add all this up, your looking around 6k. 3s can be in your driveway and have a new tb, wp, and bearings and in your car for this cost. Just saying not impossible, just saying 300hp on a 7a block and head hasnt really been done before. 400hp has been done on a 7a block and trans but with the help of a 4a 20v head, a expensive turbo and a hell of a tune.
