lol - I appreciate the compliment, thanks. But then, if I was that clever, I'd have sorted it out by now..

That looks (and sound by description) similar to the Walker pipe.. it functions, I just ended up monkey'ing with it more than I wanted to and am not a fan of the sound - but, depending on your preference, it might float your boat. Sounds like the local shop has the potential to do a nice setup for something decent. At least the back-end will be a smexy dual pipe setup.

Quick note (catching up.. lol) re: anti-seize - just remember that torque specs are for clean, dry threads (unless otherwise noted, e.g. cylinder head bolts often list as with oil). When you gob anti-seize all over the threads you're reducing the thread friction, and especially putting a steel bolt into an aluminium block.. I've been fortunate that a little dab and a gentle torque I've never buggered anything up, but I have seen the result and it's no fun to resolve that mess.

Might sound ridiculous and seem obvious, but did you count the ribs on the pulley of the A/C compressor? Guess how I know that when you ask for an A/C compressor for 2ZR and they give you one from a (10th?) gen. Corolla and it doesn't seem to jive that it came from a 2AZ model... ooops.

Looks like you're making awesome progress! Still diving into it this weekend?

Adam!


Thanks for the guidance. I'm hoping that between the midpipe I got and the exhaust guy, I come up with a decent solution. I think the exhaust should look great, but my fear is the dreaded drone at highway speeds. Hopefully the pipe with 2 cats and the resonator will combat that.

I can only imagine how troublesome it would be to try to tap stripped threads in an aluminum block as a result of over torquing with a lubricant on the threads. I'll go a little easier on the torque for sure, and no doubt I've gone a little heavy on the anti-seize. At least I know which bolts I've torqued and knowing me, I'll likely check them all again after some driving time. But, thanks for that reminder, for sure.

Haha, going out to the garage in a few minutes to check the number of ribs on the pulley. I did score some M8x1.25 x 80mm bolts today and started to attach the compressor when I was summoned by wifey to go to hockey practice.

Looks like next weekend for the swap. I have one of our students, who's very diligent and careful when working on cars, interested in coming by next Saturday to help me put the engine in. I'll start the disassembly though through the week.

Thanks again for all your help. You can't imagine how valuable the help that I've gotten from you guys has been.

EDIT: Well, the compressor pulley has the right number of ribs and the belt I got is the right one. Tensioning mechanism works great. I'll back it off until is squeaks a bit then tighten it a bit. I imagine there's a certain amount of deflection under a certain pressure to be in spec, but I probably won't get that technical.
