Prepping the SR20...
A few things need to be done to the SR20 before you can drop it in the car. First of all, I have to check the clutch to see if I'll be able to use it. I figured I'd want to replace it anyways, to save myself the hassle of doing it in a few months.

It was a good thing I checked. Someone was having alot of fun with this car before they pulled the engine. This is NOT an OEM clutch. Exedy Stage 2??

This flywheel has seen better days.
I had to replace the clutch, this ACT Street/Strip will work fine as a replcement clutch. This will hold enough HP for now.
I took the flywheel to a local shop and had them resurface it. I wasn't sure if it could be done since the wear on the surface looked pretty bad. This is the end result. Looks pretty good and only cost me $30. This will work until I get a lightened flywheel.
I'll be replacing the stock manifold for a Megan Racing Manifold. The initial quality of this manifold looks good, considering how inexpensive it is. I have decent welding skills, and the welds on this are pretty good! We'll see how much I like it after I've had it for a few months. If it's prone to crack, I WILL end up cracking it. Haha
I've also removed a few other things on the SR20 that I won't be using:
-AIV Unit
-Charcoal Canister
-Clutch Fan (will be replaced with a set of electric units)
-A/C Pump
-Power Steering Pump (might change my mind about this one)
The original waterpump and thermostat will be replaced as a precaution. In it's place will be a slightly more efficient S14 version, and a Nismo thermostat.
OEM vs Nismo Thermostat.
I'll wait on doing anything else until I know this engine has turned out to be in good condition.
