I am rebuilding the trans from my pickup. When I took it apart the intermediate shaft selective spacer ring had a pretty significant step worn in it. It would have originally been the .175 spacer. I measured the OD unit multiple times and I determined that it should have the .193 spacer. When I...

I am rebuilding my trans which had a transgo kit in it. I vacuum tested the valve body and decided to change it out due to leakage. The valve body I am going to use was modified from almost new by DTT and never performed properly. I noticed that there is a hole drilled for firmer lockup and also...

I have a couple of T18A turbo's that I'd like to use for some budget pulling fun. I have heard about these turbos needing oiling modifications and/or thrust upgrades to last in pulling. If anyone could help me with specifics I would appreciate it.

Working on my 48RE rebuild as I have time. I have a raybestos kit to add an extra forward clutch that may also be useful to add more clutches to the direct drum. The direct drum had 7 clutches with a blue billet aluminum piston and flat snap ring. It appears that there was almost no clearance...

I am going through my 48RE after realizing I had a slipping issue which I thought was TCC related. This transmission was previously rebuild after loosing reverse. The forward clutches are burned pretty bad. I wasn't paying enough attention when I pulled them out but I believe that the straight...

The other day I got on the highway and after was already up to speed I went to accelerate and noticed that RPM increased before any speed increase. There was a Code 1740 present. I replaced the OD and TCC solenoids, No change. I decided to do a little more testing which confirmed my suspicion...

I am looking to do compounds on my motorhome. 275hp 24v. right now I have a BD manifold and a HE351 with a 67mm turbine wheel and a tst powermax. The plan was to add a standard T6 K31. My dad has an early ATS compound setup that he had for his 06 Cummins that he gave me. Big turbo looks like...

One of these days I am going to start cutting compressor and turbine housings. Does anyone have any low tech tricks for measuring the inducer to exducer curve on compressor and turbine wheels? it would be sweet if it was some type of equation but I doubt it's that easy.

Getting ready to do a flex plate on my wife's 06. Last time I did one the flex plate locating tabs kept the new plate from sitting against the crank. I ended up putting on a used flexplate. Are the tabs meant to bend into final position as you tighten the bolts or did i have a bad plate?

Can anyone help me ID who may have built this turbo? 4.5 inducer. G trim 36CM housing. It looks like the nut is pinned and welded. Any tips on nut removal for maintenance and/or modification?

Looking for a 3 piece 24V manifold. I'm looking around for used before buying one from BD.

Bought a motorhome with the 275 hp motor. Since it needs exhaust manifold gaskets I was just planning on putting on a HE351 now and probably some injectors in the near future. I had a K31 and a BD cast compound adapter laying around and mocked it up with the HE351 just for fun. Now I really want...

After looking for almost 2 years I finally found a diesel pusher. It's a 98 24v 275 hp. I have the manifold and turbo off and seriously considering doing a HE351. Would one of the HX40 turbine wheels be helpful for an otherwise stock setup in this application? At times I'll be towing ~9k.

Does anyone have suggestions for temperature and pressure sensors to use for datalogging? I want to start getting my data logging setup on my pulling truck. I'd like to find a 100 psi or better sensor for logging pressures. K type thermocouples are pretty obvious for exhaust. I'd also like to...

I have an 06 5.9 with a floorit cp3 (30% I believe) A while back the FCA went bad so I replaced it, not knowing that the floorit FCA was modified. I learned just recently about the modified FCA so I I checked rail pressure with the stock replacement FCA. Rail pressure followed the commanded...

I am trying to learn some more about turbo sizing. I have a pretty good grip on how to size turbos read and plot out on compressor maps but I want to understand more about what's going on on the turbine side and how to size the small turbo in a compound setup. Maybe I'm thinking about this...

I have a set of nozzles I had extrude honed. These are unit injectors for a Series 60. I had them in a set of injectors they only ran for a few minutes before I had a plunger seize and I'm now working on getting these set up in another set of injectors. When I put the nozzles on my pop tester...

Could anyone share GT62 turbine wheel Inducer and Exducer diameters?

I had my turbo apart for some modification. I marked the compressor wheel and shaft but in reading the Holset workshop manual it looks like I should have marked the slinger too. Is this nessecary with a turbo of this size? Also, I am trying to tighten the impeller nut and I haven't been able to...

I am looking for a G trim wheel that is damaged but not destroyed. I need the contour from inducer to exducer to be undamaged and preferably have a straight shaft.
