325IX restore and build continued(turbo, e34ix diff, DCT)
Been wiring away with the new harness. It's almost done, my goal is to start it up this weekend and then schedule the dyno. This run will be one pump gas for now. looks like I'll need to redo my entire fuel system, bigger pump, lines, rail to support e85 so that will be coming later. Hopefully I can get 450 awhp on 93 pump. I'm still debating weather my .75a/r housing will flow enough or to swap to my spare 1.0a/r housing.
All covered labeled and heat shrunk.
Cam sensor ready to go also. Thanks to ppf this saved me some time making one from scratch.

Spring is right around the corner so I need to fix the major issues, like the rear main oil leak and the megasquirt.
I pulled the transmission this weekend. Also changing to the uuc m5 clutch kit, hopefully it engages better then the spec clutch.
Never fails to find more rust
New vs old
Also when i put the transmission in last year I had problems with the reverse spring blowing out the side because the case was beat up where the c clip fits. My new more permanent fix
I'm still new to tuning and I do a lot of it my self and topically motors with lower compression have a higher knock threshold. So if I happen to go a little to wild on my timing at wot that the motor will be a little more forgiving because it can naturally take more timing. Also compined with e85 or meth injection I have a better chance of reaching MBT (maximum break torque) before the onset on knock so I can reach near the full potential of the airflow the motor is capable of at my target boost.
In the end with lower compression I can run higher boost safer with less chance of knock. Plus knock is the biggest killer of performance motors and not the accually machinical limit of the internals.
If your staying low boost you really don't need to drop the compression. If it's your first turbo build and you unsure about tuning and how important timing is then it may be a good idea to run like 8.5:1 for some safety margin.
I would recommend Ross racing pistons, although I'm not happy with the rods. A good set of s50 rods with arp bolts is probably your best bet, there lighter and stronger then the m20 rods.
