AWD 94-96 700+hp Options

[Phoenixinks]

I am a celica freak, I want to take a 5sfe block and build a full race motor. I also want to rework the rear and create space for an awd system. Was wondering if anyone has attempted this yet? If so what problems did you encounter and tips for finding parts. All work will be done by me and my friend who is a certified mechanic.

A block being able to handle static pressure is one thing, a block being able to handle dynamic loads is another thing entirely. At 1000hp from a 2.2L you'll need to make 250hp on each cylinder, roughly double the stock power output of the WHOLE ENGINE will be loaded on EACH rod bearing. There's not going to be enough bearing surface present to sustain that load for any meaningful length of time assuming it doesn't fail on the lead up to that power level. Not to mention the loading on the crank and it's main bearings against the block, likely you'll run out of oil film down there too and if it doesn't spin/scuff bearings from load it'll be doing so from the block distorting. The only way you're going to get away with running that kind of power on a somewhat reliable basis is to get a custom block machined, and at that point it's not a 5S-FE anymore, it's a hunk of billet with water jackets and cylinder liners pressed into it.
And then there's the drivetrain itself, it's not going to stand up to 1000hp. Period. You'll be scouring for $20,000 WRC transmissions and $10,000 WRC differentials, buying custom axles, you'll end up with a $90,000 car that runs 10's and breaks something new every 4th run.
If you want 1000hp buy a lightly used GTR and mod it, it'll be cheaper and more reliable in the long run and hey it's a GTR!



Now, if you shoot for 500hp that's more reasonable and attainable and can possibly be made reliable. Go for that.
