4BD1T & 4BD2T

Postby rwhelan80 » Mon Aug 06, 2007 5:20 pm

THE.......4BD1T & 4BD2T...........

Hi, I like the looks and specs on these Isuzu engines. I want to put one in my 2001 4x4 2500HD. (after the C223 in my s-10)

What are some pros and cons on this engine?

Do they run on a computer?

How many miles can they go?

Sorry to stray away from the pups and luvs.

Thanks Rob

Did you see this thread?
Isuzu Chevy

It's about a 1500-series truck with a 4BD1T. Not sure if you'd want to put one in a 2500, but I guess you could. There's a link to the seller's site.

THEY ARE AS RELIABLE AS ANY ENG EVERY BUILT , JUST NOT A LOT OF HP, DEPENDING ON THE YEAR, THEY VARY FROM ABOUT 105 TO ABOUT 135 , THE 4BD1T WAS ALL MECHANICALL CONTROL AS WAS THE 4BDT EXCEPT THE D2 HAD AN ELECTRONIC TIMING CONTROL ON IT , BUT WAS MECHANICAL INJ JUST LIKE THE D1 ENGS, , THEIR LIFE AN EASY 300.000 MILES WITH ANY CARE AT ALL , THEN IF NEED BE A NEW SET OF JUGS AND PISTONS AND A SET OF BEARING AN D GO AGAIN. YOU CAN NOW BUY THE ADAPTER AGAIN TO BOLT UP THE CHEVY TRANS MANUAL AND AUTOMATIC, THEY WER DISCONTINUED A LONG TIME AGO AND SOME ONE RESURECTED THEM AGAIN .. IN A HALF TON PICKUP THEY WOULD RUN FOR EVER , THE ONLY DRAW BACK IS YOU WILL HAVE TO PICK YOUR DIFF GEARS CAREFULLY AS THIS ENG ONLY HAS AN OPERATING SPEED WIDE OPEN OF 3200 RPM. SO GEARING IS MOST IMPORTANT , 3.55 GEARS AND AN OVERDIRVE AND YOU ARE IN BUSINESS JERRY

i second what jerry said. we have a 118 hp 4bd1t in a W4 chevy (isuzu npr) with the manual and it makes a nice little truck because it sips fuel like a half ton (15-17 mpg) but you can throw 6-7 k lbs on the back and not really worry about it, and best of all still get ~15 mpg. The negatives are that it is slow. I think it would make for a nice half ton or just an around town run about that you can load with whatever, they made the 6 cyl version of these motors rated at like 160-185 hp with a like a 2600 rpm peak. I guess you could build it up just like a cummins to about 300 maybe 350 hp without alot of trouble.

Would the adaptor allow a Chev 5 or 6 sp trans to fit into a P'up like Jacks (mines identical).

THAT ENG IS WAY TOO TALL AND VERY HEAVY FOR THE PUP, IT WEIGHS ABOUT 700 LBS FOR THE 4 CYL, NOT COUNTING THE BELLHOUSING AND THE TRANS JERRY

Thanks, Jerry. A full size PU or Suburban. Would the T56 fit up to the engine with adaptor ?

The .5 sixth gear of the t56 would be nice, the only draw back is that those dont have a grandma monster torque gear. I guess this would be fine so long as you dont pull a heavy trailer.

I was anticipating a change in rear gear to something in the high 4's or low 5's to address that issue and still have 5th and 6th gear for the road.

I have no idea what rear ratios are available. Comments please ..

i'm not to sure on that one, but i dont think that the 4bd would be a good choice for a pup. Its too heavy and large.

ANY OF THE PICKUP EARLY REAR WOULD NOT LAST UNDER THE TORQUE OF THAT 4BD ENG, THE 88 AND LATER 12 BOLT WOULD BE FINE IN A VEH UP TO ABOUT 5 OOO POUNDS , AND REAR GEAR ARE AVAILABEL . 4.11, 4.45 AND 4.30 AND A RARE SET OF 4.77 , THIS IS A STRONG AXLE IT IS EVER BIT AS STRONG AS THE 9 IN FORD UNIT IT IS KINDA BETWEEN THE CHRYSLER 8 3/4 AND THE FORD 9 IN. WHICH INA 4 000 LB VEH WILL EASILY HANDLE 400 HP. JERRY
