Well I decided to supercharge my car instead of turbo (for many reasons). Soooo here is my new toy:

My GF doing some sort of sexual act with it. http://www.squirrelsw.com/supra/eatonm90girl.jpg

Well there are three ideas that I have. One is to mount it where the A/C is. It will barely fit, but should work fine. The other idea is to mount it where the power steering is and either relocate power steering to where the A/C is or remove power steering all together (this is the easiest method).

THIRD option is to make some brackets and mount it to the left of my power steering pump. This is what I would like to do. So here's the problem. I need to make brackets that bolt to the engine itself. I need help on where some places are to bolt my brackets to.

For the record, this is going to be 100% custom fabricated.

well, for bolting the brackets... the power steering bracket is a good location to start, and further back theres a fairly solid bolt on the exhaust manifold.
on the intake side of the engine, right at the back of the cam housing there are two 14mm bolts that hold the engine hook for lifting the motor.

hmm, other than that, the alternator bracket should be a good one, and i saw a while back, a strut tower brace that was also the rear mount for an eaton SC install... very very clean, and slick as hell.

was it good for your gf?

my guess would be a series II 3800 from a gm car, maybe a pontiac bonneville, or a GTP.

Looks to me that's it's probably out of a 90's Thunderbird SC:

Castings look the same, i tried to find a shot of the gtp sc, but no look...most are covered unlike the tb models.

It would be perfect.

If it can handle enough boost and air flow for a 3.8 litre engine then it will work wonders on any Supra engine 5m to 2j.

Good find, keep us posted on the project.

I actually toyed with the idea of using a strut tower mount. Big problem with this is body roll and engine movement. The SC has to Has to HAS to move with the motor. I am thinking now that I will use the exhaust manifold bolts for a bracket. Some thick steel should hold it up just fine. I thought about using some heavy duty aluminum with some fins on it to help heat removal, but I have no way of obtaining a TIG welder. I only have my MIG welder. :shrug: so steel it is (for now)
