Here are some of the mods etc......

And if anyone was curious re the old air/air set up that I actually never even ran on the road...just in the driveway

Looking good! Get that sucker finished up and start enjoying it!

Got my final part made. This will be my fill for the system. It'll be welded to the end of the cooler and out the bottom will feed the water pump.

Updates:

Drove her a little this summer till I fried a component in my MS2 board. I had a buddy fix her up for me while I was off for 2 weeks vacation. While he was in there he fixed up some of my point to point wiring also. The water to air intercooler is running really great! I have the water pump activated all the time , it just comes on when the fuel pump is on. As for engine temp cooling she seems to run ok temp wise. I have one fan kick on at 200°F and the other I think at 213°F. Over the winter I have to take the rad out from under the bus cause I forgot to get a barb/bead put onto the ends of the rad. I had one line pop off on me while idling over at a buddies house.

- As for tuning and driving it.......she goes really good! Almost scary at the top end of 3rd gear. My log says 7psi max I've had it at. That's no boost control at all just straight wastegate. I might add in a controller but not sure right now.

- I'm also debating adding in a 7" generic Hot Rod brake booster for the bus this Fall/Winter also.

- I also will be adding a PWM Idle control to get a little more RPM in the mornings when cold.

Built a cold air intake for the engine compartment. Trying to get a little cooler air into the beast and not suck the hot air from the engine area. Had to drill a hole where the battery used to go and then relocate the air cleaner into that pocket. Also grabbed one of those Outerwear nylon covers to help protect it.

Don't know if any of you had seen the engine compartment ?

Glad everything is still kicking, homing to bring my EZ36 vanagon up this fall.
Trans and engine in place, just everything else to do.
(MS3/fuel tank/suspension/exhaust etc etc)

Still very happy with the MS2 and the conversion. The cold start IAC valve was such a great feature to include .

If you want to put a 3 wire iac in like late vanagons and many european cars had (high airflow) you can create the 180 degree out signal by tapping off fidle and the inverted signal feeding it.... still needs a pair of 3-4A drivers, but has a lot more authority.

There is a 2 wire version of those IACs with a return spring, could never to get one to work as well as the 3 wire, although I was using used ones, so probably just because I'm cheap. they are all ~14-15mm ID, made by VDO.

Yep , I already have one in there now. It was a great feature I added in.
