Yesterday, I set out to get some sound clips of my exhaust. Ended up just driving around like an *******.

This is quickly spiraling out of control:



I plan on getting the T5 installed this winter. Shouldn't be too dramatic, especially now that I have a garage to work in. Doing this engine swap in an open driveway last winter was ridiculous.

The 16v will be a much longer term project. Next year, at the soonest. That said, when I start that, I'll want to sell my 8v head, injectors, fuel rail, intake manifold, downpipe, and maybe manifold/turbo set up. All that stuff would make an OHC swap relatively bolt-on for some 140 owner...

PS: have you run the Forge valve backwards yet?

We're going to have to wait for quite a while. Plus, I just got this thing tuned as is and it rips at 12 psi!

Yup, tried it both ways and it's basically the same, noise and operation-wise.

Interesting. In my car it makes very different sounds depending on orientation.

Hmm. Maybe I didn't actually switch it. I've tried so many things so many different ways on this car that I'm losing track.

Yes! Great progress and a promising update. Love the video. Hooning is why you bust all those knuckles.

Thanks! It's easy to forget that when the thing just sits for so long. That's why I want to do the T5 and 16v in two separate stages, rather than just ripping the thing apart for another 6 months.

By the way, I switched the Forge bypass valve around and it makes less noise at part throttle. Nice, audible bypass sound when letting off, but no weird miscellaneous whistling. Thanks, Harlard.

Weridly enough, it seems to work better mounted backwards

Glad that tidbit helped.

Boring update:

I have decided to put the 16v thing on hold more or less indefinitely. This car needs so much more work to be totally reliable, so I'll spend my time on the T5, rear end/LSD, suspension bushings, etc.

Also, I have been trying to use a TurboXS HP boost controller to get a steady 15 psi, but I couldn't get any reliable performance out of it. I over boosted it a few times, and during that process, lost a freeze plug. That was really annoying, and I never want it to happen again. All the retainers on the market are for B230s, with no option for a B23. I made this and I think it'll work:



When I was pulling the turbo off, I found that my Aeroquip return hose was on the verge of cracking from the heat. Don't use it for that application, I guess:



Replaced it with a braided steel hose from the local shop:



Hopefully I can just drive it for a while then get the T5 in before the Coastal Range Rally in February.

Can't commit to selling yet. I pretty much want to get the 8v running well on 15psi, get the fuel system and drivetrain sorted, then decide if I want to make more power.

I'm 90% sure that at that point, I'll want to make more power.

".....on the verge of cracking...." LOL - I think you went right past the 'verge' line....glad you caught it before it failed in operation. FWIW, I think your approach of taking care of fundamentals first before 'upgrading again' is a sound one.

Yeah, I guess I should say it was on the verge of cracking clean in half. Lucky I happened to lose a freeze plug before losing an oil line.

Are you running a b21ft-b23 stock bottom end?

Stock crank and rods, and I'm using the B23ET pistons that were in it from a previous rebuild. I also put BMW squirters in it, but whatever.

Hello Tfrasca, where did you find this downpipe flange TD0$ -> 3" ?
Thank you, very nice car. Regards, Kay

Noah's welds are great, and it was rad to watch that happen.



This is what I ended up doing for the alternator bracket. It's bolted to an M12 stud that I tapped into the block, and the tensioner is made from a combination of B20 parts and a generic curved arm from the local parts store. It's pretty tight between the idler arm mount and the alternator, but I'll have to wait and see how much engine movement there is.



Here's the beginning of the 3" downpipe. You can also see the repair I had to do to the exhaust housing stud when it snapped off yesterday. I ended up having to drill it out completely and cut a shoulder on the backside to use a bolt. Pretty lame, but it'll work.



Pretty slow progress, but now that the radiator is mounted I can work my way forward with the intercooler and oil cooler, and things should progress pretty quickly from there.

Going back a few posts but I also found my aeroquip drain hose cooked through during an engine pull. Actually mine was cooked THROUGH underneath a DEI heat sleeve, I can only assume it didn't leak because it was on top of the hose at a bend.

I replaced my hose with same and put it on the consumable list. My hose cooked through despite being wrapped in DEI heat sleeve then sprial wrapped in DEI heat tape. I just don't think any rubber hose is going to survive surrounded by a header. The braiding won't hurt, but I would plan on keeping an eye on that hose all the same.
