Does anybody know if the 2.3 TDI shares the same bellhousing/transmission with the 2.3 petrol engine? I noticed on some parts site that the part numbers for the clutch for the 2.3 petrol and the 2.3TD are identical. How about engine mounts?

THE TD CLUTCH SETS ARE INTERCHANGABLE WITH THE 2.3 GAS ENG , THE BELLHOUSING ARE NOT HOWEVER IF YOU HAVE THE DSL TRANS AND THE GAS TRANS YOU CAN SWAP THE FRONT PART OF THE TRANS , FROM THE 2.3 TO THE DSL TRANS IF THEY ARE BOTH 5 SPDS , THE 2.3 MT MOUNTS ARE DIFF THAN THE DSL THEY ARE TALLER (THE CUSHIONS AND THEY BOLT ON DIFF,) HOWEVER THE DSL MOUNTS WILL BOLT TO THE GAS FRAME MOUNTS THEY ARE THE SAME SPOTS

Are there other major differences in the transmissions? Ratios, Starter position, etc? That would cause installation problems?

Did the 2.2 TD come with an intercooler at anypoint, maybe an overseas version? I was thinking it might be easier to get a 2.2 from overseas than trying to find an older domestic vehicle with that engine?

Do you know what the power and torque outputs are for the 2.3 gas and the 2.2 TD engines? Would an intercooled 2.2 have significantly higher values?

I had an 83 T-Bird Turbo Coupe (non-intercooled) 2.3L 5spd that had decent power but I know the intercooled T-birds had much higher HP and TQ values.

I've been following the thread where acy76 is installing a 4JB1-TC (2.8L?) into an 88 4cyl 5spd doner. I would assume this engine would require extensive modification to fit in a GenI (my 86)?

Did Isuzu make any other diesel engines other than the 2.2 and 2.8 (and the 3.1, 3.0, etc..)?

Thanks Jerry!

Jonathan,

The Isuzu transmissions are a little bit different when compared between gas and diesel models. The aluminum casings are different in that the gas transmission has the starter mounted on the passenger side, while the diesel transmission has the starter mounted on the driver side. Also, the internals (gears, bearings, forks, etc.) are the same no matter what engine you are dealing with. Now I do believe the gas transmission has different gear ratios than the diesel transmission, which could help or not. So when doing a diesel conversion make sure you at least have the diesel transmission case. The 2.2 TD engine makes 80 HP @ 4000 RPM and 125 FT LBS @ 2500 RPM. The 2.3 gas engine makes 96 HP @ 4600 RPM and 123 FT LBS @ 2600 RPM. I didn't want to interrupt on this reply, just want to try to provide help and info. Hope I was of some help and thanks.

HEY SALVY ,, RIGHT ON THE MONEY , ACTUALLY FOR JONATHON IF YOU COULD EVER LOCATE A A 4JB1 OR ANY OF THE 4J SERIES ENG THEY WOULD BOLT INTO THE 86 ABOUT AS EASY AS IN TO THE 88, THE BIGGEST PROBLEM IS THE EARLY TRUCKS DID NOT HAVE A REMOVEABLE REAR CROSSMENBER AND THE TRANS IS A BEAR TO GET IN AND OUT , BUT THEY WILL FIT , GET THE TRANS THAT GOES WITH THE ENG AND YOU WOULD BE BETTER OFF AND THEN CONVERT THE HYDRAULIC SET UP OVER TO A CABLE RELEASE , TAKES ABOUT 3-4 HOURS BUT CAN BE DONE, AS FAR AS THE INTER COOLERS GO I HAVE NEVER SEEN ANY INFO ON THE AVAILABLITY, ON THE 2.2 ENG , THEY STOPPED USING THEM IN THE LAST OF 87, AND THEN SWITCHED OVER TO THE 4J SERIES OF ENGS, AND THEY DID USE A NO OF DIFF CONFIGURATIONS OF INTER COOLERS ON THEM, MOST ANY SMALL COOLER CAN BE MADE TO FIT THE 2.2,AND AS FAR AS HOW MANY DSL ENG DID ISUZU MAKE WELL LETS START WITH THE 1 LITER 2CYL DSL , ALL LIQUID COOLED , AND THEN ABOUT 12-15 VARIATIONS OF THE THE 3 CYL 1.1 -1.5 L, 4CYL 1.6N THRU THE BIG TRUCK STUFF OF 5.3 LITER THIS IS A BIG 4 CYL 190 HP TWIN CAM 16 VLV, THEN THE SIX,S START WITH ABOUT 5 L, UP TO 13.50 LITER, THIS IS A BIG 6 OR HOW ABOUT THE BIG BOYS A V10 15.015 LITER, OR THE V12 AT 18 LITER AT ABOUT 24 00 LBS ------JERRY

I think I've found my next conversion candidate. You guys think I'll need to upgrade the torsion bars?

THAT WOULD BE A SIGHT TO SEE , I PICKED UP ONE OF THESE ENG S FOR THE TRAING CENTER MANY YEARS AGO AND WHEN I WENT OT GET IT THEY SAID DON,T BRING A PICKUP , SO I TOOK A 5 X 12 2 AXLE UTILITY TRAILER , THEY SAT THE ENG DIRECTLY OVER THE AXLES AND YOU SHOULD HAVE SEEN THE WHEELS SQUAT, THE FAN ON THAT SUCKER IS ABOUT 28 INH IN DIA AND THE WIDTH I AM GUESSING IS AT LEAST 36 INCHS WIDE AND AT LEAST 48 INCHS LONG, IT IS A 90 DEGREE ENG SO IT IS WIDE , MONSTROUS EX MANIFOLDS , THIS ENG WAS FOR A BIG CAB OVER TRUCK , AND WAS ACTUALLY USED AS A LOCOMOTIVE ENG IN JAPAN FOR A WHILE BECAUSE OF THE ENORMOUS LOW SPD TORQUE 387 HP AT 2500 RPM AND 1250 FT LBS TORQUE AT 1600, I THINK THIS WOULD PROB PULL A TROOPER REAL FINE

Be sure to keep us frequently posted on the progress.... <img src="/forums/images/graemlins/lol.gif" alt="" />

Thanks Salvy and Jerry! I appreciate the info. The 2.2 is a bit lower in HP than the 2.3 but that's to be expected, but it wasn't as much of a difference as I might have suspected. I was really suprised that the 2.2 TQ was not much higher than the 2.2. I could live with the lower HP if I gained substantial TQ increase. I guess I might just check into the 2.8. I've been doing some browsing through some Aussie and British boards to get more info on the 2.8 as well. Any additional info you can provide would be appreciated. Do you happen to know the HP and TQ values for the 2.8? If not, I'll browse around. I think the 2.8 gets about 25 - 35 MPH depending on the vehicle, the driving conditions, and driving style. Does anyone have any anecdotal information about either the 2.3 gas or the 2.2 TD? I never drove the truck with the 2.3 to find out because the original engine needed work when I got it and I never finished the rebuild. My old '84 1.9L was really good on fuel economy for a 4X4 and not terrible to get moving, not a V6 or V8 of course, but tolerable. My V6 Montero only gets around 17-18 MPG but it's also pretty heavy.

I saw on a FAQ post somewhere (maybe here?) that the '86 had a 21.9 gallon fuel tank? If so, that's pretty good. My Montero only has around a 24 gal tank for the V6 to suck from. I don't think the old '84 1.9L had but around a 13 or so gallon tank but I might be mistaken as it's been over 10 years since I drove it and since it was drivable (another project but that one is for my dad).

Salvy, I figure that whatever diesel engine I might get that I will try to acquire the tranny and maybe even other stuff such as the motor mounts and crossmembers if possible just so I can compare or even fabricate if needed.

Jerry, I noticed you were posting about the crossmember and hydraulic/cable issue on another thread. That's interesting and good knowledge to have if this comes to fruition. I take it the diesel has a hydraulic clutch assembly? My montero does too. I think I might be savy enough to make a conversion if needed but it is good to know I have such knowledgable folks to give advice.

Jerry, will that a/c compressor I bought from you still fit the diesel engine? Whatever I do, I've got to have air down here in hell, er... the south. I can't believe I was born and raised here because it seems the older I get the more I dislike the heat, or maybe that's just because I let myself get lazy and sit in a/c all the time?. Do you still have that axle assembly from the 88-91 Trooper with the LSD and disc brakes? I've got other things to wory about first bt I was just curious.

Thanks again for all the info!

Jonathan

I think the 2.8 (4JB1-T) is rated at about 110 HP and 175 lb/ft. TQ. I think these numbers are for the non-intercooled version, as I was unable to find anything for it specifically.

Performance modifications are fairly straightforward and can yield some impressive gains.
