I put a turbocharged v2203 in my ****** 3B. My egt's are right around 1100 at 15 psi when I really put my foot into it. I kinda think thats a little too high. The engine came out of a reefer trailer and was a carrier genet. It is a DI engine. I put a stiffer spring in the governor and originally turned the rack adjustment screw out 2 turns. It smoked more than I liked, and my egt's would get up to 1200. I turned the screw back in 1 turn and thats where it is now, much less smoke and the power is still good. This Jeep is going to be used mostly off road but will see road time, mostly local roads, no freeway driving. It's basically a rock crawler. I think I'm gonna try and intercool it with an air to air intercooler in front of the radiator. I'm running an electric fan. Space on these old jeeps is very limited and I will probably only be able to fit a 2 inch thick intercooler. I'm looking at Bell Intercoolers as it looks like they will custom make whatever you want. Do you think an intercooler that is 8 x 12 x 2 approx. will help with my egt's. Any help, tips or ideas would be appreciated.

 

looks like a nice conversion. you left out your turbo model, and your injection pump timing spec? also what sort of gearing and rpm's are you spending most of your time running.
I think that the rock crawler guys like air to water intercoolers, and highway guys like air to air IC. on the low speed rock crawler it is difficult to get enough airflow over the air to air intercooler.
you might get better results with a timing advance bump, bring some of that fire back into the cylinders, instead of driving the turbo. most Carrier motors were spec'd out with pretty retarded IP timing.
Of all the mods you can do next to get a little better egt control, the timing advance is probably the easiest in my opinion

have fun let us know how it goes

 

It is an aftermarket gt 1544 and the timing has not been changed from the carrier setting. I think the engine will spin up to 2800 or so but this one won't spend that much time at WOT. This is my first Kubota, what does it take to change the timing and how much should I change it? How much of a drop do you think I'll see in my egt's? The turbo came with the adapter and kit I got from Overland Diesel. I've got one ton axles in this thing with 5.13 gears and my trans is a t-98. thanks for your help.

 

To advance the timing you need to remove the shims from under the injection pump. Most will have 2-3 shims, take them all out gets you @ 11deg advance. When I did mine it dropped the egt's @ 200deg. and improved performance and drivability all around plus it didn't hurt my mpg's.

 

Overland is not supporting you? while I was writing FTE filled in,& I will back what he said,
Long story short, most likely you will end up removing all the shims under the pump, and that will most likely get you about 9-11 deg advance, It depends on where you are starting from timing wise.
need to look at your carrier engine model to get your timing spec, you can get it from the carrier stickers on your valve cover, Do you have the carrier service manual. there is a free download or link in one of the threads somewhere. Quite a few of the Carrier motors are set in the 4-6 deg range. Except the late (newer) models were already factory set to 9+ deg

As for what sort of results you will see, and how much to advance all set ups are a little different, and it is up to you. I think the cummins guys are staying under 16 deg advance unless they are full race, and a lot stay in the 14-15deg range. I am currently running 10 deg advance, and a similar smallish turbo to yours (rhf4h), I can still get to 1150 to 1200F, but I have to work at it pretty hard; for me that means a smallish longish (under a mile) hill at 65-70+mph and about 2000 rpm, and high teens for boost into a headwind. Off topic a bit, I can see a 300F change in EGT at 70mph with just a headwind or tailwind So load makes a huge difference!
If you have a 4 or 5 deg engine, you might see a 200 f drop with a timing advance. for me changing timing and switching to the small turbo dropped my egt about 200 total. I am no expert, my understanding is ; generally speaking more advanced timing is better for higher rpm's

I tried to copy my manual it has not worked yet.

all engines except 26-00120-00 will be less than 6.5 deg advance.

 

Thanks for the quick replies. Greg at Overland is awesome and has always been very helpful and I just thought I'd post on this board cuz there are a lot of Kubota swap guys on here. What do you guys think a maximum sustained egt would be with these little diesels?

 

Before the timing change I tried not to exceed 1200deg, since the timing bump I haven't seen it go much over 1000deg and I have a lot of hills and passes so I'm working the motor.
