I did a little boost control experimenting using the factory solenoids several months back and it seemed to work a little, but as I continued to increase boost via JB4 it was apparent it wasn't going...

Yep, I installed the tank and bracket, but as you mentioned the charge pipe doesn't fit. I will be modifying that this weekend. The stock charge pipe might fit, but I want to retain my Tial BOV.

With the current setup, it would be a 30 minute procedure to step up to a GTX3582R, which Garrett claims up to 750 HP in the same exact frame size and similar spool.

Yep, I will be using JB4 + BMS Flash via Cobb.

Yes, just need to finish installing it. I'm curious to see the affect on AFR from putting the sensors pre-turbo.

Thanks! Yeah, should only need a small sample of gases for the widebands to do their thing. Since exhaust travels in pulses, there should be a pushing and sucking effect (insert joke here) on flow...

Thanks, guys. Had to stop working on the car today to go out to dinner. The steakhouse is packed!

I got the hot parts back from coating. I'm currently working on reassembling everything and hope to have it up and running next weekend.

Geometry plays a key role in max RPM. A long stroke motor has to be built much stronger to sustain high RPM than a short stroke motor would need to be. A chainsaw revs at really high RPM's, but...

The N54 crank and rods are unquestionably forged (per BMW documentation). The pistons probably aren't. Regardless, the N54 has been proven to withstand ~275 BHP / liter so far and we're still...

Hey, posting a video of an M3 beating a 335i is fine, but... oh wait, that didn't happen. Not only is the OP spewing bull$#@!, but the 335 clearly pulled ahead before the end of the race. This is...

Okay, well in the video I just watched (which is obviously different than the one you were watching), the M3 got the hit and still fell behind the 335.

Also, I have have been reading up on the N54...

I considered going with Swaintech (and really wanted to), but it was about a 3 week turnaround, and I would have had to ship the parts to them. I'm trying to get my car back together sooner than...

LOL. Maaa! Meatloaf!!! I'm $#@!ing misfiring here!

"Can we put it on right now?" LOL. Awesome. I thought my girlfriend liked the roof rack I got her for her 328xi, but this reaction is even better.

I'm not trying to argue, I've just never heard anyone else mention those issues with coating. Actually, my hot parts are with the coater right now being done. Hopefully no issues arise.

Wow, I've never heard of ceramic coating causing a header to crack. I know this happens with wrapped headers since the wrap maintains much more heat than ceramic coating; but never heard of ceramic...

Yeah, them $#@!es can weld.

That's good to hear! I would definitely have one of those if they had been available when I was turbo shopping. Nobody had them (or knew when they'd be available) at that time.

This prototype was probably cast before most people realized the O2 sensors had to go pre-turbo. As far as the wastegate, you can either get a T3 housing w/ internal gate (probalby good for up to...

Okay, I was up under my car a few minutes ago and was able to confirm that the E90 chassis has these threaded bolt holes next to the transmission as well. I would have to assume the E92 does too. ...

Wow, someone negged this? Anyway, I hit you with a green fist.
