The crank pulleys on the 3800 and the fa20 are almost the same size but the fa20 has a redline 1300 rpm higher than the 3800. So it will be rotating the m90 at about 13500 rpm which is perfect for about 300 wheel on E...

I'm also building a water to air intercooler for it so I might in the future opt to switch out to the 3.4 pulley and take it up to 330-350 wheel.

your trying to hit 300 without an intercooler? Are you at least running wmi?

I cut off the long intake on the back of the m90 and I'm fabbing up an intake that will mount the stock 86 throttle body that will swing around to the front with piping and tie into my perrin CAI. This will all be mounted onto the stock intake manifold.

Sounds similar to the sprintex, stock plastic manifold or metal? I hope you’re not using the plastic one to support all this under load.

The S/C cost me $90, the coupler $13, various aluminum and such around $30. Panel bond $30. There will still be some additional costs, but remember, I've already proven I can do flex fuel for $156 and I've ran that for over 3 years so, as far as being able to do what I say, been there done that.
a ff kit is easy, that’s like saying I’ve walked to the store once so i can go run a marathon.

p.s. as far as posting the cost, It should come in at WAY under $500, $500 is allowing for any unforseen costs. I have a CNC mill, 5 3d printers, a gun smithing lathe, a cnc lathe and a welder so I'm not including the costs of what I already have that allows me to fab pretty much anything I want.
That’s if you don’t account for and value your time though

Imbedded a few responses.

Sounds like a cool project none the less, hope it works out and you get some dyno numbers or some solid pulls in to validate what you’ve done.
