Isuzu - Round2

[FL cruiser]

The 6.2 sat pretty far forward in the engine compartment. The new drivetrain will need to sit 3" further back to make room for the intercooler. Even still there is a ton of room behind the engine. The rear of the engine is still probably 4" forward of the 2F location.

The good news of it sitting far forward in combination with the NV4500 & adapter being 7 1/2" longer than the H42 is that there won't be any driveshaft or oil filter clearance problems.

Oil pan might need some further mods though.

I modified an FJ40 air cleaner. Big miscalculation though. The elbow won't clear the hood anywhere the air cleaner can be mounted.

Guess I'll have to search for a 62 or 80 lid.

I had the same problem when trying to fit my air cleaner up. I ended up using an early 80 bottom and a diesel 60 lid for my air cleaner. I tried out my wife's 96' 80 series air cleaner and it fits even better with the low profile lid. I think that is what I will use for my next one since they are a lot easier to find than an HJ60 cleaner. I have an early 80 series lid that you can have if you want to play with fabbing up an attachment.

Great looking swap so far! Super simple since your rig already had the NV4500 in it...

Is that the reason you chose the 4BD over the 4D34 mitsu motor you had lying around?

 

[Elbert]

Night before last took the old girl out for it's last ride with the 6.2. It has provided me with over 10 years of good service. Kind of like losing an old friend.

But I look forward to having to the added MPG and having an engine with a turbo.

The 6.2 comes out barely fitting through the rad support opening.

What was your setup with the 6.2 engine...bellhousing,trans, adapters, transfercase?

Did you have any issues with clearance for the NV4500 shift arm (clearing the dash or heater ducts)?

Bell housing or adapter would require some ingenuity since none are available to mount it to an NV4500 or H55. I'm sure it can be done, but my CAD/Solidworks/Machining experience is non existent..
Not as big a deal, but the Mitsubishi would require an ECU which I don't have.
Plus I robbed the turbo off the Mitsu for one of the Isuzus.

I'd still like to use it in something someday. Glad you guys are pioneering the way.
Can't wait to see what fuel mileage you get. I bet it's good.

6.2, GM NV4500 bell housing from 96 truck, GM NV4500, AA adapter, Split case transfer.
The little lower plastic heater diverter piece had to be removed, shifer had to be angled back slightly, but no other shifter issues.

Don, thanks for the offer. Much appreciated, but for now think I'll check out the low profile later 80 lids.

Looks great.

I am sending you back the coil and ignitor you sent me. I pulled them before I sold the my truck.

The battle wagon is going to have one hawt sister. I am Looking forward to another one of your awesome builds. It is Defiantly inspiring work that you are doing

I would have liked to see what you came up with for a MT option... ah well, I'm sure someone will someday.

In any event, you work looks top notch, can't wait to see the finished product!

 

[FL cruiser]

A little more progress is being made.

I fabbed up some motor mount brackets, a transmission crossmember, and crossmember brackets.
.250 wall tubing was used as well as .250 steel plate.
Pass side crossmember i made to slide in behind brake and fuel lines that run along the frame and bolt on using some existing holes.
Crossmember will be supported in leaf spring bushings for added vibration isolation.

 

[FL cruiser]

Drive train is in!

Motor mount brackets are tacked in.
Trial fit anyway. It all eventually comes out again, everything gets final welding and engine compartment, brackets and crossmember will get painted.

 

[FL cruiser]

Good clearance in most areas.
A big plus to the engine being forward is no driveshaft clearance issues.
Less oil pan/diff clearance though. Oil pan will need to go under the knife again. A small portion of the pans front corner will get removed.

Steve,

Did you push the engine way to the passenger side? My motor mount is much shorter ob that side. If so, is there a benefit?

With the trans your running, it sits way more forward than mine and allows easy access for the turbo intake. There is a stock 4bd2 intake tube like mine on ebay for $50.00 if interested.

Looks good as usual!

Plenty of room in the A/C compressor steering box area.

Next project is radiator and intercooler mounting.
Welder ran out of wire. Done for today

It might be an optical illusion. The engine sits 1" left of center. Starter is about 3/4" off frame rail. Pass side mount bracket ended up being 2" longer than drivers side bracket.

There's probably no big benefit where the engine is placed. Ya move it one way to make clearance for something, It takes away clearance for something else on the other side.
I guess best placement is wherever it fits best.

 

[doug720]

Maybe just an optical illusion, but your mounts look a lot longer than mine do? Just curious. Where are you mounting the inter-cooler? Keeping the ac condenser in the stock position?

Doug

 

[FL cruiser]

I see what you mean. It kinda leaves me scratching my head after staring at the pictures.

A/C condenser stays up front. Intercooler will be between the radiator and radiator support like yours.

I'm kind of up in the air about where to fasten the lower radiator mount. The radiator support is sheet metal. I'm afraid due to the added distance/spacing of the radiator and added weight of brackets and intercooler, it could lead to stress cracking of the sheet metal.
I'm also a little concerned if I attach the lower bracket to the frame and attach the upper portion of the radiator to the support, body flex might have an effect on the radiator as in eventually making the steel sides separate from the core. It does seem like there is some rubber between the upper mounting bolts and bolts to allow some flex though. Kind of leaning toward doing it this way. This vehicle won't see any hardcore trail use or flex.

 

[doug720]

Weird on the motor mounts?

Do you remember how I mounted my radiator and intercooler? I bent some steel into a channel and used all the stock mounts in the front panel. For the lower mounts, I made new raised mounts welded to frame so I could use the stock vertical mounts and bolts on the side of the radiator. Both the rad and IC are rubber mounted. Let me know if you want a pic.

Looks good

[FL cruiser]

Doug, I look at your pics every other day A couple of your ideas were borrowed.
I used your method of modifying the Isuzu intercooler to fit around the Toyota radiator.
