Hi all so my trans in my fj62 went out for the second and last time so now im putting in a chevy TBI 350 and 700r4 out of of a 88 suburban i have called the guys at Land Cruiser NW in portland OR and they are getting me the trans adapter and motor mounts from advance adapters and a wiring harness from howell engine developments ( the guys down at land cruiser NW have been great with above and beyond helpfulness they are the best!!!) so here is the question what else do i need to get or know before i go after this thing i will have more specific questions later but i thought i would talk to guys and see what you guy know and yes i have tried the search bar and read for hours and hours and post i read was different so your guys help would be great:cheers: Joe
 
Search my username and tbi. I did this swap only with a 93 tbi and 4l60e. On the last or second to last page i line out every single part i used.

I love mine. Hands down best bang for your buck smog legal swap with fuel injection and overdrive.

As i type this I'm actually wishing i could drive it right now. Its sitting in my garage in AZ collecting dust while i work in kc.
 
I'd post the transm. On here for 50 each. Better than the scrap yard. Mike
 
sounds like you have most of the parts lined up. You probally need to look at a electric fuel pump setup and what you plan to do with your power steering hsoes, also A/C if you want that to work.
 
I was told that the fuel pump on the fj62 would work for the TBI system is this not true? the power steering i was hoping to get the ends changed or make an adapter to use the 350 pump. i was wondering with the AC if i could use the 350 AC compressor on the stock fj62 system by just making new hoses that went from the 350 pump to the fj62 system. one other thing i have read both ways on drive shafts that i have to cut them down and that i dont, let me know what you guys think any thing to save some money we have twin 2.5 year old boys so all the money i can save the better thanks all :cheers: Joe
 
i have a stock toyota PS pump in mine with some clever rigging, my fuel pump is an external one on the inside of the passengers side frame rail, its an AIRTEX E8094 electric. it starts up on the ACC key turn.

got some other tec specs if you want them. for instance i have 3 radiators and my exhaust manifold is off an 89 Chevy Caprice
 
I would use the GM p/s pump like most of the guys have done on the various engine swap threads here. You can buy some an adapter fittings that screw into the steering gear and then you can get a GM ps hose modified on one end so it it will mate with the AN (pressure side). You can cal also then come up with a a/n to push on hose setup for the ps cooler (low pressure side).

Yes I would run your GM A/C Compressor and the rest would be the Toyota A/C components and then use a custom hose or two to mate the two. You can see how people have modified the wiring under the hood to control the GM a/c compressor.

I would think the 62 fuel pump would work, you may have to look into what pressure it works at to make sure you are good for the TBI.

I think Kurtis did an engine swap just like you are talking about.
 
Jester,

I'm on the verge of swapping in a 350 TBI myself. In fact this weekend I pulled the motor from the donor 87 Chev and it's in the back of my PU ready for the trip to be rebuilt. I'm trying to save some bucks so I've scavenged the entire wiring harness intact (eng comp & under dash) to attempt its use as well. We'll see how that goes. I've scavenged anything and everything I think I may (or may not) be able to use in the swap.

The one thing though that I'll definitely need is a speed sensor for the 60 I'm swapping into. I'm ready to order one from here: http://www.jagsthatrun.com/Pages/SpeedSensors_Speedometer.html
Looks pretty simple, just plug and go. For a 62 maybe the speed sensor you already have would work. The 62 was efi right? It would also depend on the signal it used (two or four pulse). You'll need a two pulse for the TBI.

My donor motor didn't have AC so I've purchased the same AC pump and brackets that came in my other 87 PU. Familiarity, right? Will also need to change a couple of pulleys then need hoses too and figure out how to get it to operate. I understand it ought to be straightforward. I'll find out when I get that far.

Hopefully, I'll get my build up here when I actually get in to it. Good luck.

I'm doing the same swap in my fj80, using a 92 chevy as a donor. Mark's adapters offers a part to allow you to use the Toyota viscous coupler and fan with your chevy motor. I think I'll add that to my list. You may check and see if your exhaust manifolds fit or you may need block hugging headers. You can adapt Toyota temp and oils pressure sensors to chevy block and keep stock gauges. If you want to run a tach, you'll need the interface for that too.
 
- Change the fuel pump to a TBI specific one. I recommend a Walbro: http://www.tanksinc.com/index.cfm/page/ptype=product/product_id=331/prd331.htm. Keep it in the tank to avoid vapor lock and other fuel delivery issues.
- Keep the oil and temp sending units from the Toyota motor so your gauges will work.
- Be sure to hook up your tach wire from the GM coil. Yes, the tach will be off since you are switching to a V8, but your air conditioner will work without having to do any special wiring and hacking.
- Use the GM PS pump, and the GM A/C compressor. Adapt your lines to them.
- Now would be a good time to do a DIY McNamara gear since your Tcase adapter should have a brand new input shaft. https://forum.ih8mud.com/60-series-wagons/397916-diy-hd-mcnamara-gear.html
 
Just sayin', but if that 700R4 was behind a 350 in a Suburban, and has over 100,000 miles - it's probably close to dying as well. The 700R4s were not all that durable. The 4L60Es were quite a bit better.

uh they are basically the same thing with some minor differences.

Have you seen pictures or know details about this "kit" from Mark's in regard to the Toyota Fan Clutch? What advantage would you get from going with that item from Mark's? You better look into what belt system you plan to run on the front of the engine and what pulley arrangement you plant to use.

TBI engines are single belt....the old school 5.7 were v belt as well as many other old school engine setup.

I asked Mark's about details on their adapter by email numerous times...no reply as I was interested in see what it was. I assume its some kind of adapter that mates the yota assembly with a GM pullley but the key will be which GM water pump pulley.


Generally speaking I think you would be better served to stay with the GM accessories, fan clutch, fan, etc...

does any one know how much i have to cut my FJ62 drive lines or can i get away with not cutting them and what size after market tac will fit in the stock spot i was thing about one from auto meter or some thing of the likes. Joe
 
Elbert,

Mark's is slow to reply, but I wanted to check out the part. If it doesn't work out I'll pay shipping to return it. What I hoped to accomplish was using my Toyota radiator shroud since they chevy fan is larger. I think if everything mounts up right i will have ample cooling. I figure I can at least check it out and let others know how it works.
 
hey jester-

i did this exact swap (350 TBI/700R4 into an FJ62)... check my profile for a link to the thread. i didn't finish the thread but have a lot of information to save you some headaches.

the easiest way to deal with the tach is to buy an adapter from Dakota Digital... converts the 8 cylinder signal to your 6 cylinder gauge & allows you to use the stock gauge as is.

http://www.dakotadigital.com/index....tegory_id=287/home_id=59/mode=prod/prd127.htm

i used one in my swap and it has been great... though i have never dyno'ed it's accuracy.

driveshaft length will be determined by where you end up mounting your motor-trans-tcase... MY SUGGESTION is to bolt the three together, lower in place and then mount up the rear crossmember and trans mount and bolt it into the stock location...then adjust from there (i.e. check motor height for motor mounts, distributor to firewall clearance and t-case shifter location) this MIGHT save you the hassle of fab' ing up a rear crossmember and may save you from rear driveshaft issues.

ultimately though, driveshafts are one of the last considerations, and are adjusted once you have everything else in place. a simple measurement and decent drive line shop will be all you need.

there are quite a few differences between swapping a 60, 62 and 80, so don't think that what works for one will work for the other...

FYI... i live in Troutdale, OR. and work in the gorge... feel free to PM me for more details or if you want to check out my swap... it's still a work in progress, two years later.\
