I'm kinda surprised I didn't have a few people jumping on the offer to help me do an install and haul the old kit away.

Not sure what route I'm gonna take yet, I'll think on it a bit.
I'm driving it to Cali tomorrow morning to dump the camper shell off of it and then it's going to the paint shop.
I'll give some thought to turbo options while the truck is down.

If I was local at all I'd be happy to help. Unfortunately I'm in WA and MT. Even if the kit would fit my '85 IDK if I'd put it on w/ the 21.5 compression ratio in the '85 and the tired IP and injectors...the truck's been with my mom in ID where she gets a decent amt of use out of the old girl while I've been in my current job/living situation for the past ~4 yrs. I'm settling back into MT over the next 6-8 months and I'll probably take the truck back to MT and do some work on it. A turbo would be nice but I'd have to get that compression ratio down...which may turn into a rebuild long story short pretty sure it needs more work than just the IP and injectors heh.

I have thought about cutting the stock box up to make access a lot better on things. Did you guys notice an improvement in any way with the remote filter setup? To me I could see the stock box as a huge heat sink that just preheated the intake air. I was going to use a canister style air cleaner to get outside air to the filter.

Why do you feel you would need to lower the compression ratio to install a turbo? Even the factory IDI turbo still ran the ~21:1 compression. If you keep the boost levels reasonable (~10ish lbs) the IDI will stay happy.......

Honestly just more of a feeling that it's too high to really take advantage of the turbo (though...lol...going there the whole IDIT gets into chasing that brass ring around anyway). I'd have to go through the engine pretty thoroughly before putting a turbo on the poor old girl anyway...it needs clutch work (yay throw out bearing) too. My experience with the turbo'd (factory) engines that had the higher ratio was of having head gasket issues...though this was on trucks we were working a lot, and hard...and mine wouldn't be seeing that sort of work either so it'd probably be fine. I've got a tow pig for anything bigger. For such an old truck it's always had decent power, and really, good mileage (12-13MPG ... and that's at 70-75 w/o OD - thanks to a 3.54 rear) ... just has a tendency to be a bit of a smoker and I really want to clean that up (probably will help the mileage a decent bit too) and probably can't really clean it up with just a fresh IP, injectors, and fixing the timing.

Lowering the compression ratio will make it even more of a smokey pig and will not want to start cold. It's been proven that you don't need to touch the cr on these trucks unless you are trying to build a 2000 ft lb torque drag project like what hypermax did. Use head studs and you will have no limit to how much boost that headgasket will hold.

It's an idi. They need higher compression than most DI diesels. No need to adjust the compression when putting a turbo on. The engineers who designed these things back in the day knew what they were doing.

Mine spooled a little faster afterwards, about 1500-1600 rpm instead of 1700-1800 like before, anymore seat of the pants power....no.

I started to chop mine up after I dropped a wrench under it, I was so fing tired of dealing with that stupid piece of **** banks kit and when I had to take it off AGAIN to get the g.d. wrench back it was never going on again.
