Don't get me wrong, a PnP harness is much easier to install. But I personally find that to be relative. The Motiv-provided harness isn't exactly difficult: find a wire, tap a wire. That's not rocket science. It takes an hour. Sadly, their design just doesn't work very well. It's my personal...
The big issue is that the the Motiv-provided harness is junk. It's honestly terrible. So many weird connectivity issues. They all went away when we swapped to a PnP harness from Tensility. The controller itself is good, but nobody should the Motiv-provided harness even if it's an easy install...
And now we see the vacuum line for the BOV runs towards the firewall, which tacitly confirms my theory they're tapping the brake booster line as a vac reference. It's one of the few places on the car that actually does that function.
No. 100% no.
Exhaust "backpressure" is a meme-level myth. You want ZERO backpressure on a turbo. Hell, if we could make the exhaust a massive f'ing negative pressure vacuum it would be even better for a turbo.
I know what fitting you're talking about, and I was always under the impression that this barb on the front of the manifold doesn't actually provide vacuum. If you look at MAP from the car, the manifold doesn't really hold strong vacuum like other cars d/t BMW valvetronic. I don't believe that...
You wouldn't need to touch the bolt if I'm right. It would just snap onto the breather as a MITM thing.
//edit: Judging by the construction of the 2pc brake booster hose, I think you could also install this thing between the two hose halves. I believe the male end of the fitting on 44763A in...
Until proven otherwise, I'm going to assume this uses the BMS N54 vacuum adapter (or something like it) to provide a vacuum reference.
I believe it sits on the engine block end of the brake booster hose. The hose runs from an air valve that plugs into the block up to the master cylinder on the...
Bizarre electrical gremlins on the Supra are usually the result of a weak or dying battery. Charge it to full on a battery tender before drawing any conclusions.
My Twisted Tuning transmission mounts. They're fantastic if you spend your life in sport mode above 3K RPM, but they're just miserable for daily driving. I'm taking them out and will be trying a softer 70A bushing from PowerFlex. They're still firmer than stock, but much softer than the TT...
I've driven them in the rain three times. They suck in standing water. Very unnerving, as they cannot evacuate water very fast. But they're okay in wet roads if you don't drive like a dink. Overall I just take it easy, and it's been okay. I don't think they'd do well in downpour conditions.
But...
The trick to removing the breather is to not bother pulling it with your hands. Squish the clip, then use the twisting leverage of a thin screwdriver inserted into the seam to pop it free.
