1967 NADA 109 cant make up my mind on this 2.6 power plant

Very nice lump - works well in a RRC/110/109 as its a originally a marine diesel it revs well, has enough power not to break everything in the drive train and is pretty frugal..

What's the availability like over there?

We have quit a few of them up here, they where in scout II's. Im thinking with this motor I could use the t-19 tranny that came with them and adapt the tcase to it. Im not sure of the perfomance and what gearing it would need to be happy. Im wanting to run 3.54s so i can keep ring and pinnions strong and use the tcase to underdrive it if need be.

IIRC Scout IIs with the SD33 had 3.08s stock and 3.73s (3.55s?) were optional. Keep in mind the Scout did not have an overdrive transmission.

Sorry to burst your bubble on the Stage 1 axles but they are 24 spline outers and only 10 spline inners. Early RR or Disco diffs are a source of replacements.

.

Well I thought you might want to know that not all stage 1 axles had 10 spline inners :wings: as i just tore my axle down and it has 24 inner and outer. Maybe the front will be 10 spline inners like the early rangies? that would make sense to me.

Well that will be good since my axles are 3.54 and if i go this route will use the T19 that is matted to these. This would leave me needing to buy the adapter from T19 to series Tcase.

Something was bugging me about the info I posted above so I went and starting digging around the books in the shop...

In 1980, wide ratio T19 (6.32:1 first) came with 3.55 gears. Close ratio (4.02:1 first) came with 3.73.

The SD33 Turbo made 101 hp at 3800 rpm, 175 lb-ft at 2200 rpm. Boost was 6.5 psi. The engine had oil squirters for the piston skirts and the bottom end and cam was enlarged with larger journals.

The previous non-turbo made 81 hp @ 3800 rpm, 138 lb-ft @ 1200-1600 rpm.

The engine was originally setup to run on 3.55-3.73 axle gears with stockish sized tires so I wouldn't worry about re-gearing or anything.

The engine itself might be interesting but I wouldn't spend "real money" to buy an engine with such lacklustre output personally. It's just old at this point. If you are going to run old stuff then stick with what you have unless you can get a good, known well running SD33T for only a few hundred bucks.

Also, IH is notorious for having "non-standard" mating surfaces between transmission and transfer case. Verify that there is an adapter to mate the IH version of the T19 to the LR transfer case before committing to that path. I may be off-base on this but Spidey-sense is tingling so I'm going to mention it. :)

Sorry for the failure to elaborate. All rear sals have 24 splines so I didn't think to define which axle I was talking about. I was referring to the front.

Hi Ed,

This might be a little bit different direction, but I am really taken with this solution and if I were to do it again would give this a lot of consideration; how about a Cummins B3.3 for diesel power ? http://www.expeditionportal.com/forum/threads/67258-Cummins-B3.3-Powered-FJ60

It's all mechanical. Parts should be no problem and it is compact and light... As much as I like the Mercedes diesels, this one makes a lot more sense and is much newer.


Im really wanting a diesel the more i research it, the chevy is a simple conversion and i do have it but the dependability of the diesel calls. On another note ive noticed theres not much talk on the 5spd 380 and 230 tcase i have. wouldnt these units make for a strong unit and give an over drive for long road trips.

Another find is that my axle the salisbury and front diff are 3.54 ratios:wings:. Im pretty sure this also means that my front axle is a 24 spline unit since it was from a 80s stage one. I was thinking all this time that since it was a leafer it would have been 4.70 but have found info that stage ones came with 3.54s and 24 spline axles.

I do all my own fabrication and mechanics so parts will be the only hurdles while on the road.
Thanks for your time its keeping me motivated to research the posibilitys.

Very clean conversion!

I talk with Mathew Jackson at Adavanced Adapters and he has some very valid points at installing a American V8. Im a diesel perv and its hard for me to sway but he has done a great job on his Series 88 and it is a clean install. Im still in the decision stages and the motor is the hardest one for me to decide on.

Thanks to all who have posted and keep the ideas comming.

The cummins looks sweet but spendy as well.

Cheers Ed
