88 K5 Diesel - Tranny/Trans Adapter Install

That sounds like a promising upgrade, drive pressure is often overlooked and a big deal with increased boost and stress on the entire exhaust system.. if you can lower it and gain anything that's a win win.. sounds like they had their heads on when they designed it.
 
Just went through the exercise replacing the head gasket on my cummins. The Mini Maxx is great but it pushes the DP WAY too high. Options were wastegate or custom tune (chose the latter). But if I can keep the DP down and still make ~10lbs then I'm ahead of the game. Lower EGT follows.
 
Side note: If you're Canadian don't bother ordering from James Oaks Ent. Ordered my snorkel from them last Friday, just got a refund from them with a note that their calculator didn't do the shipping correctly so they've cancelled the order. Odd that every other vendor calculates shipping to Canada without any problem...
 
Top of the page should read "Thread Tools".

Also, have you looked at Heath Diesel for the wheel?
 
Ok good-ish news, looks like I can get my hands on an HX35 relatively cheap. Anything specific to look for with them, or just the typical no end/side play on the wheels?
 
Quicker spool with the 9cm housing that the 12cm basically there is two basic versions the HX35w and the HY35w the latter being the smaller housing but will increase drive pressure.. By how much I don't know, the Hy is stock on auto trucks so it spoils quicker..
 
Says it's a HX35W, I was actually considering the HY for the quicker spool before but as long as it's wastegated it'll still be better than the Banks. After the cummins fiasco drive pressure is my enemy.
 
I think you'll be fine, the 6.2 flows a lot for it being such light duty so I'm sure it'll run really nice.
 
Alright I caved, and I blame you guys and your peer pressure entirely! Picked up an HX35W yesterday. Won't get time to start tomorrow, but I'll have parts showing up this week so be starting the tear down.

Looks like there will be some work to do seeing how the turbo is clocked, but should just be a matter of cutting, rotating, rewelding the exh output. Then some creative plumbing on the air side. Nothing too strenuous.

I do like that the WG is boost actuated though. Any way to adjust its response to 12ish psi, or will this be a home made turbo master?
 
You could make a turbo master. Or get a wastegate for it like a real one that welds in the exhaust.. Or leave it internally waste gated.. Just read up, I'm not sure what those came from the oem pressure wise. Usually if it's a high psi charger the wastegate will not work correctly at lower pressure. Again I'm not super familiar with the setup. Could be totally Wong.
 
Well talking with some of the DP guys, I'm going to have to cut and clock the exh outlet, and cut and clock the compressor housing, apparently I got the worst kind for using on 6.2/6.5 lol. Just my luck.



 
Im not following you, what part of the EXH outlet has to move? the downpipe or the flange?
 
The downpipe, but the main thing is I've got to clock the whole thing because mounting on a 6.5 manifold I'm going to end up with the drain up in the air and the inlet pointing down-ish. I'm not going to worry about it too much; deal with it when I've got everything going back together and I can see what the angles look like mounted on the truck.
 
I'd put an intermediate flange in to relocate the turbo before I started to cut it.. Just my 2cents

It looks like I can clock both sides actually, so I'll tear it down and play with it a bit. Luckily I have another fully dressed 6.5 on my engine stand, so I'll mock everything up before it goes into my truck.
