The MSA5D 5-speed fully synchro manual transmission that comes with a 4BD1T has a 5.67 1st gear and 5th gear is 1:1 (no OD). Everyone that I know that has experience with these transmissions say they are bullet-proof.
The down side of using the Isuzu transmission is 1) mating the output to a LC TC, 2) setting up a means of shifting as these are not top-shifted but rather use a series of external rods and levers to connect the transmission to the shift lever.
I'd love to see someone undertake this swap project and post their experiences here.
sorry what does the abreviation NPR mean?
if the engine+transmission+t-case fit and are on the proper side then the obstacles are getting the wierd side mounted shifter through the floor and fabbing up new mounts and crossmembers?
Anyway, with isuzudieselswappers.com that is a huge assett.
I've never pulled the head on a 2T but pictures that I have seen show a removeable precombustion cup in the head and the piston is essentially flat whereas the 1T has a significant combustion pocket in the top of the piston but the head is flat.I never knew the 2Ts were indirect injected, I had heard from several people that they preferred the 1Ts which you could probably intercool?
These engines also come in 4wd NPR. THe Isuzu t.case has the front drive shaftto the right like a LC and the rear, from memory,slightly to the right.
Lengthwise its similar to a LC.
Now it might be a pain procuring one in the US but would save some work further down the track
i'd like to see this swap too. Astar, the diesel isuzu trucks that you can get this motor from, where do you find them. i dont think ive seen any in canada. although i have seen lots of bighorn diesels in New Zealand(trooper variant). Which engine adapter are you refering too? you say nv4500. what will work to use h55 transmission do you think? also they sound like a good power. i would be scared to throw in a heavy torque monster like cummins 12 valve. also since you have a couple of these could you post a couple pics for the rest of us.
i think one day we'll convince someone to take on this project.
There were never any 4wd NPR's imported into the US. Using the NPR 4wd trany w/TC could be a great approach, especially if both the front and rear output shaft were offset like a LC. Any idea where I can find more info? Next time I'm in Costa Rica, I will check to see if 4wd NPR's were available there.
I found a couple of NPR's on ebay for around $800 each. Both had engine issues but that doesn't really concern me as I plan on rebuilding them. For around $1500 you can get a complete overhaul kit including new piston, liners, bearings, valves, valve springs, valve guides, retainers, valve seats, gaskets and new oil pump. Essentially, you have a new engine.
Regarding the NV4500 - someone makes an adapter to connect this transmission to the LC TC. I don't remeber who.
Regarding pictures - I plan to pull the 4BD1T out of the NPR in the near future. Once I do, I'll take some pictures. I'm not sure that i know how to post them but I'll try. I'll also get some exact measurements and weights
thanks david! my buddy sully emailed me the same link yesterday. this particular engine has an auto behind it so the adapter won't be a problem. comes with it! and we all know that i dig autos the most.....
Have just bought myself an 88 Izuzu Npr Engine, Head has been re-done. All trinkets are included. Starter, Alternator etc. etc.
Am going to be installing it in a 76Fj40 as soon as I have stripped the bottom end of the block down.
I Think I am going to start a new thread in the 40 section, Because really I am building what in my opinion is an expedition truck. But the first part will be the engine transplant and running gear.
I will post here when I strt the thread. And keep looking back here to watch for any tips
