" Hey everyone, I just wanted to update this thread since most of these projects seem to quietly disappear into the night. I too have moved on (to another platform), so this project has concluded. I planned on doing a 6AT to 6MT transmission swap, but found that my engine was hurting. Cylinder#2 plug was coated in oil, and the car seemed to be losing coolant with no obvious leaks. Rather than building the engine and still having to address future trans issues on a 7 year old car, I considered moving up to a newer 335is 6MT and putting the single on that. Well, I ended up driving a CTS-V and liking it a lot more than I expected. In addition, it's a bolt-on 10 second car with the right combo, so I'll be spending most of my time over on CaddyBoost now
Anyway, I had a lot of fun; but it was A LOT of hard work. After messing around with the tuning for a while, I ended up putting down 570whp / 484wtq with 93 + meth through the stock DP back exhaust. Afterward, I changed from the 1.03 A/R housing to a .82 housing and continued to tweak the tune a little bit, but didn't re-dyno.
Throughout the project, I have gotten a lot of PM's with questions from people having a custom setup built, or building their own. Feel free to keep them coming and I will try to help if possible. I reverted my car back to stock before trading it in, so I will probably throw a "for sale" thread up soon for anyone who may be interested in a cheap turbo kit.
Thanks for following along! "
