94 FZJ80 6.2 conversion begins!

[browndog]

Excellent, Smithers.

I'm really interested to get some feedback from you regarding the amount of space you'll have between the exhaust manifold and the passenger side shock tower (looking for turbo clearance). I'm thinking of having a machine shop make a manifold shim or custom manifold so that I can avoid having to modify the shock tower. Might not be necessary.

[FL cruiser]

I did manage to make room to get the engine over to the left by putting a 1" thick steel plate between the steering box and the frame.
There is an advantage of moving the engine to the left. Drive shafts and drive line is centered in the original location. Shifters are centered and fan lines up with the fan shroud. Also oil pan is further from hitting the oil pan if the vehicle doesn't have a lift. But I guess it's better to put the engine where it fits best. All other issues can be worked around.
ATX turbo kits could be had with a rear center mounted turbo that was just above the intake at the rear of the engine.
Not sure, but maybe vans had rear center mounted turbos.

[browndog]

FL Cruiser--

The rear mounted turbo has quite a lot of appeal but I couldn't find any information about where they were located on the engine. I am curious if there would be firewall clearance issues in this location. If not, that is the option I will take.

[FL cruiser]

Also oil pan is further from hitting the oil pan if the vehicle doesn't have a lift

correction: oil pan further from hitting front diff.

Yep, Not much in the way of pictures of rear mounted turbos on the net.
There was an article on a Hummer website a couple years ago that showed an install of a turbo setup from a van. I had it bookmarked, but it's no longer there

Correction: It was ATS not ATX was the company that made rear mounted turbo kits.
Not much info on that anymore. I'm sure they probably long quit making them.

I would have to see a picture of some turbo manifolds to let you know if they will fit. I think I could move the engine down a bit and gain a little space between the steering and the manifold. Right now I am waiting on a new oil pan to see if I am going to be able to move mine down any. I currently have the military pan and it is very deep, I think even where it sits now the axle would hit the pan. Again I am hoping to be happy without the turbo but I am sure room could be found to put on in it. There seems to be alot more room in the compartment with the V-8 than the 6. I am even going to be able to install the transmission/transfer case first then install the engine and bolt it up to the bell housing. This is going to be really easy with the V-8, there was no way to do that with the 6, even with the head off. I think once I get it all set up I could pull the engine in a matter of a couple hours if I ever decide to change things.

[smileyboy]

kerri it coming I am wanting to do this too but with a 6.5td

[rtarh2o]

From the pictures I have seen I think the 6.5 TD might fit. It looks like the turbo is pretty high on the passenger side. There seems to be all kinds of room on the passenger side of the engine. The problem for me would be wiring. The great thing about the 6.2 is the fact that it is mechanical. I am removing most of the Land Cruiser wiring right now, it will be nice to have an uncluttered compartment. I am thinking if I am not happy with the power I will add a Banks turbo, I can do that for around $1,000 and from some tests I have seen the 6.2 with the Banks has about the same output as the 6.5.
I haven't gotten much done the last couple weeks but hope to get the engine in over the Holidays and will post some more pictures

I hope you have been making good progress on the swap. I know that taking pictures was the last thing on my mind during my conversion.

[rtarh2o]

I am currently waiting for parts so I can install the engine (brackets and manifolds) the place I am getting them all from has been incredibly slow but in the mean time while waiting to get the engine installed I have been doing things like cleaning window channels, making armrest/cupholders, wiring the engine, routing fuel lines, cleaning the tank etc. All things that might have gotten overlooked or done too quickly if I had the parts already. This way things are being done slowly and hopefully correctly! I will post more pictures once I have some noticeable progress made, hopefully this weekend! Can't wait to get it on the road, I am having to borrow my mother's mini van! Rusty

[made4surf]

Sounds like when I did mine, I waited three months for my used engine after I pulled the 2f. Once you get everything though, it goes really fast. Here's a pic of mine, but I'm sure yours will look better.

[made4surf]

[tntoyota]

Gayles 6.? sidewinder has the exhaust manifolds exiting towards the front goofy when you look at it but very functional.....I'm just catching up is that what you got?

[rtarh2o]

Yours looks great, can't wait for mine to be in! Looks like you are using the factory brake booster with a line from the vacuum pump? I was told that wouldn't work so I installed a hydroboost, was pretty easy so hopefully I will be pleased. I purchased a military 6.2 without any accessories and the military headers. The headers won't clear the engine mounts so I am waiting for some stock manifolds to come in along with all the brackets for the accessories. The guy was suppossed to ship them about 4 weeks ago but the still aren't here. I live in a fairly small town and have only found 6.2 in the salvage yards and it only has about half what I need. I am going searching again tomorrow since it looks like the parts didn't come in again this week! I will get some pictures posted tomorrow of the little I have done. How does yours drive, what about mileage? I am planning on a WVO conversion once I get it going so I won't be as concerned about the mileage but I am hoping for at least 18 mpg.

I think your talking to me, so I'll answer.

Brakes don't work to good now but I've had problems with the brake booster even before the swap. I'll probably do the hydroboost thing as well because new boosters are pretty expensive.

I had the same problem that you are going through. Military engine, no parts, no brackets, and mine had a bad injection pump. Luckily, I found a seized 6.2 at a local junk yard for $400 with all the brackets except for the AC stuff.

Driving it feels great, more power, better fuel economy, and sounds cool on the road. On my recent trip to Baja I got 18-14mpg and thats with the fuel in my pump turned up for a little more pep.

Hope the search for parts goes well and thanks for the compliment.

[rtarh2o]

My engine suppossedly runs great, a friend heard it running and watched them do a compression check on it before he picked it up for me, so hopefully no suprises once it is in! I went the military route hoping to get a good engine. I have all the accessories, went the v-belt route because that is what the engine was set up for, just waiting on the brackets now. I still didn't get all the brackets in last week so called a local salvage yard to see if they had any 6.2's (they didn't have any a few months ago when I bought the military engine) They have an early 90's with the serpentine belt set-up, wish I had gone that route because the A/C compressor is on the correct side. If I don't receive the set of brackets from the place I have been waiting on this week I may go get the complete serpentine set-up and try to trade in all my accessories for the newer serpentine belt. I did pick up some manifolds so hopefully this week I will get it installed, I am just making sure I get everything done while the engine is out and easy to get to. Still waiting for enough visible progress to post some new pictures.
18 mpg was your highway mpg? That is about what I figured, I was thinking 18-20, what gearing and tire size do you have? What rpm are you turning at the 18 mpg?
What are you using for a tachometer?
Thanks Rusty

[rtarh2o]

By the way, did you get the A/C on yours? It looks like it might be on the passenger side if that is what I am seeing? What compressor did you use and what brackets?
Rusty

I'm glad to hear you got a good engine but the bracket situation doesnt seem like too much fun. Just remeber that if you get a serpentine setup that you will need a fan that spins the opposite of the pulley system.

I'm running 32's with a 3:7 ratio, and I can cruise 70mph at 2K and get 18mpg as long as there are no big grades.

The tach I'm using is from auto meter. It fits nicely in a 60 series but I don't know what will work for your 80 unless you mount it somewhere like your dash.

Rusty

I havent been able to get the AC or brackets yet but they will eventually be mounted on the drivers side above my power steering.

[rtarh2o]

That tach looks factory in the 60 dash, I don't think there is a spot for mine like that. I am going to play with getting the factory tach to work. I will probably stick with the V-belt set-up I have, just wish the guy would hurry and get my brackets to me.
Rusty

[made4surf]

BTW, I forgot to ask you if your injector pump solenoids are 24 or 12 volt? I know that mine originally came with 24v solenoids and almost all military 6.2s were that way as well?

[rtarh2o]

The IP was 24v so I changed it and the glow plugs to 12V. Another day and still no parts, if they aren't here by the weekend I think I am going back to the local salvage and buying the complete serpentine set-up, what was it you said about reverse rotation fan?
By the way, I got the same 6.2 Diesel badges for my fenders too.
Rusty

[FL cruiser]

The water pump spins reverse rotation with the serpentine setup. If you use a fan off a vehicle with a clockwise spinning engine, it will push the air back toward the radiator. The CCW fan blades are pitched the other way. If you go with the serpentine setup you will need the a CCW fan clutch and water pump too.
A serpentine would be nicer. Earlier V belt equipped 6.2's w/o the rubber padded lower pulley are notorious for belts loosening, squeaking and needing tightening. Not a bad problem, I learned to live with it, but annoying for people that don't like tightening their belts every few months. Knock on wood I haven't had to adjust mine for 8 months.

[rtarh2o]

I am hoping my brackets will come in this week, if not the local salvage also has a mid 80's 6.2 with the V-belt set-up so I will probably just go get all the brackets off of that, just kind of a pain dealing with the local salvage yard. Unfortunately they didn't have either of those cars when I was looking a few months ago but I guess it is good they do now. I will probably stick with the V-belt since I already bought new A/C compressor, Alternator and P/S pump, too much money in all of that to change now. The only upside for me on the serpentine set-up is the fact that the A/C is on the passenger side like the Toyota. I am probably going to take it to an A/C shop and have them run the lines and fill it up so I guess it won't be my problem.
Rusty

[made4surf]

Good luck with the parts, and please let me know how the AC works out.

[6840]

Brian,

I'm using the factory FJ62 shifter with my 4L60E. Should be the same shift pattern as the 700R4. We made an adjustable length arm for the tranny, and by trail and error, found the correct length for it to work. Simple and clean. I can send pictures next week if you want to see it.

Will
FJ62, Vortec 5.7, 4L60E

[rtarh2o]

Lokar makes and adjustable shift linkage kit I am using (see earlier in this post) it is really nice set-up, not too expensive and works really well, easy to adjust
Rusty

[rtarh2o]

6840, do you have the shifter working? I haven't tried mine yet (still waiting to get everything installed) but am wondering about gears. Does the 4L60E have L, 2, 3, D? The 80 has L, 2, D if I remember correctly, I guess I will have to modify the indicator.
Hope to have some new pictures up next week with my progress, had to find another exhaust manifold so if it fits in the frame rail I should get it installed tomorrow, from there hopefully things will go a bit faster!
Rusty

[6840]

Yes, the shifter works fine. The FJ62 tranny has the same shift pattern as the 4L60E (PRND321) so it was just a matter of adjusting the relative lengths of the two levers and connecting them with a threaded rod. I can send you some pictures if you like.

[rtarh2o]

I am going to start working on my linkage tomorrow. I have a kit by Lokar which is pretty much the same thing you did, I considered fabbing my own but the Lokar kit was only around $40 so I thought my time was worth at least that much. I finally got the engine installed today once I finally got the correct drivers side exhaust manifold on. I ended up installing a 1" body lift to give me room to run the exhaust and WVO fuel line stuff. Hopefully it will go a bit faster now, mostly just little stuff to do, fuel lines, coolant lines, oil coolers, finish electrical, radiator, the list goes on and on but nothing major is left (I hope!)
I will post some pictures tomorrow.

[rtarh2o]

It's alive! Finally got it started today! I have been doing alot the last few weeks, haven't driven it yet though. Going out to get pictures to post, check back!
