I've got this left iover. Started as parts I would chop up to work an intercooler into a H1. Or fit a bigger turbo. Now just spare. $100.00

Im going to grab one of these ffro Home Depot. Weber iGrill Mini App-Enabled BBQ Thermometer 200hr battery life. Smartphone app. Ill put it in my transfer case to start. Then move it to my diff and even throw it in my geared Hummer hub. Monitor temps from the cab wirelessly. Its only 50 bucks....

My 4L80e in the Hummer just started acting up.... No codes. Works fine cold. When warm looses OD, then third. Then starts slipping in first and second... Fluid is fresh one year ago. 100 000 miles. Dipstick is showing fluid. Strangely there is loads of rust at the top of the dipstick....thats...

I just picked this up (for Free!) And was considering it for my 6.5 TD. Im definitely foido a turbo update and likely a 4" exhaust in my Hummer. And a intercooler is coming into play. My question is - what is this turbo in relation to the HX 35 snd HX 40? I like free! Im opening it up tomorrow...

Ive been through nearly every variation of cooling upgrades to try and get a 6.5 TD in a Hummer to keep cool while working. Balanced Waterpump, Tanked Radiator, new pressure cap, Kennedy early engagement fan clutch, Duramax fan. Even a wired up fully 100 percent locked fan. Its a basically stock...

Im starting to gather parts for my intercooler build and need the pair of intake runners and bridge manifold between the two for chopping chsnging and welding back together. If anyone had a Teds hummer takeout or dead van they swapped into a pickup and these were going spare let me know. Cheers...

I searched the threads for info on the 6.5 Wicked wheel (now in v2). Not too much in the last couple of years. What were the results on a stock engine? Or is it billet snake oil? Im driving a centermount turbo on my hummer and its the claim of lowering EGT's that catches my attention. Im a max...

I changed out my fuel filter 4 months ago just after I got my truck but its situated well back and under the windsheild on a Hummer so I never got a good peek down inside. I started my FTB mod today so pulled the whole FFM out. When I took the top off and pulled the filter I nearly dropped the...

Just got a k type thermocouple installed on my 6.5TD Hummer . I put it right outside the no.8 cylinder on the exhaust manifold. I know they are usually further back near the turbo but I wanted top temps that the engine is making as a benchmark before I start playing with my performance. Im using...

Im in my H1 at the side of the road. My engine just died in traffic and I had enough momentum to get off the road. My 20 amp fuse for the ecm/lift pump blew. I replaced it and the truck started, fuel pressure was good, it ran for 30 seconds and blew the fuse again. If i replace the fuse again it...

I've been using the Torque app for about 6 months now and love it. Logging, custom layouts for multiple OBDII readings all with high/low warnings etc. Screenshots of 4 or 5 readings as they are happening have been great for showing others to get diagnostic help. Ive managed to work out some...

GM standalone transmission controller for 6.5 Diesel. Suits a DS4 to DB2 conversion. I recommend Bobbys guide for the DB2 conversion as a read if you are considering this. I bought it to put a 4L80E in a Humvee but ended up with a H1 that already had a 4spd. Now its surplus. Price 100 dollars...

Whats in the Stanadyne fuel additive for our lift pumps? It stinks funny, I cant identify any known solvent or fuel from the smell. When it evaporates it leaves a sticky residue. I had a general browse around but couldnt find any reasonable info or guesses. Anyone have an idea?

Just installed my lift pump pressure gauge. Close to 4 psi at idle. 2-3psi driving at my old man pace. Hits 0psi (possibly negative pressure) on hard acceleration. Glad I did this. Looking for a lift pump soon.....

Just had the PMD fail in my 96 TD K2500. Cruise control became intermittent about 2 months ago. Then I started it up in a parking lot and just as it fired the throttle blipped up to 2000 rpm and back to idle for about a half second. I thought perhaps I had my boot touching the accelerator and...

My 95 TD has GM-5 engraved on the turbo. I hear about GM-3 and GM-8's but cany find info on what it designates. Are they sizes, flow rates, revisions, housing sizes, production years, just for fun? Thanks Sand
