What blower you using? how much was it? and where/how did you get it?

I always watch Richard Holdener and he was doing an m90 ls build. The m90 wasn't enough for the ls but it's perfect for a stock block fa20. So I went to the yard and found one in awesome condition.
It's almost like it was made perfectly for the fa20, the output hole lines up with the big square portion of the stock intake manfold when the pulley is in perfect alignment with the serpentine belt.
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.
The 3800 N/A was also 200 hp and the gen 5 on 6lbs made 260hp on a super conservative factory tune. Now my car isn't stock so it's making closer to 240 bhp so it ends up being perfect for about 300 wheel on the stock pulley on E. I ported the gen III m90 so it should be close to on par with the gen V.
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.
The bearings are all good on the m90 and it's the cleanest used S/C I've ever seen. The guys at the yard were surprised I was able to find one. I did get a replacement snout coupler and I'll replace the S/C oil though.
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.

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.
