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.

oh ok, well i already bought most of the parts that i need (they are listed above) and i bought all the tools to put it together and what not, including the engine stand! and im only at 4.5k so far! just trying to see what else im missing before i pull out my motor and start redoing it. better to have everything mapped out before jumping into it. Thank you for the link! im still going through it smile.gif

Not to mention that the 4.5k is including the clutch i bought for my tranny which is rated to withstand 400lbs of torque.

Note: You can't just have a good motor you have to have everything else built up as well! or else its pointless having a great built up motor! Ill have to start a progress build on here as soon as i get all my parts! I think you all will enjoy it!
