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.

Transmissions don't handle HP, and cars don't produce HP.

With that said, I know of an MR-2 1ZZ turbo with around 300-320 whee torque with aftermarket LSD doing hard launches and using Nitto drag radials. He does 11.8s 1/4 mile. C-series transmissions are not weak by any means (except C60 which is the ****ty 6-gear that comes with the Corolla XRS or Celica GT-S; those break on stock 2ZZ power)

He has never had to do anything to the transmission and it's been well over 2 years turbo, 260-280-320 wtq across its life.

@OP: You should've fit an LSD if you had the transmission out. However since it's already done, the most important component in making power is the tuning solution. If you don't have proper tuning you can break even the best forged engine.

Your right they handle torque but i am lost on what your trying to say about cars not producing HP, could you clarify this for me????

Also that's awesome to hear! Seems like I should do alright then. But yes your absolutely correct! A good tune is a must! I will be taking my car to a dyno shop to get it tuned as soon as I get this build complete.

And now I never looked into a limited slip differential for these cars, that idea never even hit me, Could it be done to these front wheel drive celicas? specifically the ST??
