aeromotive pump Aeromotive Stealth Electric Fuel Pumps 11540

i cant hear other than when the vehicle starts and isnt running


im also the crazy bastard that has a second pump in the system with a 1/2" line plumbed out for future use and now a surge tank/pump ill be putting in not to mention the hot cam going in shortly

So the factory pump should work fine then with a 5.3! I am going to start my swap next spring. Currently searching for a good donar for rebuild looking into a gen 4 motor.

i ' m running stock pump and stock fuel line on 5.3 swap and no problems i did found specifications for land cruiser fuel pump and compared it to supra pump if i remember right there was almost no difference
on the other hand my old engine was really tasty 9 MPG vs new 5.3 averaging 18 MPG that same pump supplied enough fuel for old engine no problem

Is there another oil pressure sender that will work with the LC guages? I found an adapter (Pipe Fitting 1/8" BSPP Female to Metric M16 x 1.5 M16X1.5 Male Brass Adapter) that fits the Toyota sensor and the GM engine (top of block, behind intake manifold). But the Toyota sensor is to big around to fit - there's a bolt and such next to the hole.

Looking around I see some sensors that are much smaller - this 93 4Runner for example:

But I'm not sure it will behave the same electrically.

I know there are taller adapters available, but this route is possibly alot cheaper and i can probably get the sensor locally.

If you had a way to simulate pressure through and air line or something you could compare resistances. It would be my guess they're pretty similar though.

 

[goranvolvo]

easiest and cheapest option is to go on GM oil pan you can how i did it , all you need is to drill hole and cut ner thread
i used milling machine do cut it down bit just because i have milling machine but it can be drilled way it sits

if you r going to use any other sensor you need to match resistance range to the gauge

2007 5.3L ls in 1991 80 series

I did not remove old lifters just left evruting in engine but i did disconnect it and wires r removed

I am using a sensor from a 3.4 5vzfe engine. Its 1/4" british pip thread I believe but fit into 1/4" npt and sealed well with some teflon tape. I modified my temp gauge with the resistor mod. So it only starts reading temp at about 170 degrees. 190 is about 1/4 on gauge. 210 is about middle on gauge. The below link is to a aftermarket one. I pulled mine off of a used motor laying around the shop. Im not sure how it would read without the resistor mod. But the adapter for the cylinder head hole 12x1.5 to 1/4npt is easy and cheap to find.

What threads are on the stock temperature sensor?

I have an M12-1.5 nut that threads onto both the GM sensor, Toyota sensor, and the plug that came out of the hole at the back of the PS head. But the Toyota sensor won't thread into that hole??

I'm guessing it must be some parallel pipe thread that's really close to M12-1.5, and the box-store nut is just sloppy enough that it will go regardless.

I think its 16x1.5. I believe Mark's 4wd has a adapterfor it.

My next question regarding doing this this swap is there a good post regarding g the wiring side of things, are most of y’all running both the gm and Toyota computer? I was looking into the mega squirt engine managment system or is this just a waste of time? For reference I’ll be swapping a 91 with a 3fe in it. Also was planning on using the dirty dingo engine mounts seems like the universal kit may work the best for adjustability of engine placement.

All that is used is the GM ECM. Megasquirt would be a tremendous waste of time.

Heard that that's what I needed to know, but what are you using the Toyota computer for? Or is it completely bypassed altogether? I’m trying to wrap my brain around this part. Getting the engine tranny and transfer case in for me is the easy part this is not lol

I used the Toyota ECM for some extra cash when I sold it. Lol

Do you have the EWD book for your year model 80? I did the swap on a 1fz truck.

See if you can find or download a copy of the Electrical Wiring Diagram book. It show where and what every wire is. Colors, etc

This thread is for V8 swaps to 80 Series Toyota Land Cruisers.

Your truck frame must start with the following: FJ80-0xxxxxx or FZJ80-0xxxxxx. Of course, it can also start with an HDJ/HZJ iteration. Only the Aussies yank out perfectly good Toyota diesel engines to swap V8 power into them... Oh and our friends in the ME as well.

Your frame number will always be on the RH side of your truck, on the frame, right near your front RH shock.

Please post direct links to your build thread, post pertinent technical information, and discuss TECHNICAL aspects of V8 swaps into the 8x platform.

No diesel V8's; only small block or big block petrol V8's.

And, yes, Toyota Industries and Bodine Alumimum 4.7L and 5.7L engines are included. One cannot discount how perfect Toyota V8's are in the 8x Series Chassis. Of course, this option requires the serious expertise.


Please keep all discussions pertinent to only technical aspects of petrol V8 swaps--the real "doing" of a swap; no selling of swaps, no vendor sales, no discussions of merit vs a Toyota power plant.

Just: "I did a LT-1 swap and this is how I did it, these are the parts I used, these are the resources I relied upon (pertinent informational resources), this is how much it cost, this is what I would do differently next time, these are the people that did my swap, this is something new I discovered about X."

Keep it empirically-based and keep it authentic.

Drive fast and take chances.

-Sport mode - Check

-GM A/C-Check

-PRNDM mode in shifter with PRN123456 digital read out- Check
-No money Left - Check


Just getting ready to start for the first time next week. Will have a complete build thread and will be glad to try and answer any questions that are at my pay grade. Other questions will need to go to the shop that is doing my build. Lot's of little challenges but anything you desire is possible with these builds if you have time and money to do it. Even with a GM LS drive-by-wire engine the factory cruise control lever can operate the cruise control as it did stock. You can have manual tap shifting and tow haul and sport mode if you desire. I admit I desired all of it. Did I mention time and money? More details and info soon.

I noticed the beginning thread listing VIN specifics. Just want to confirm.....I have a 1997 FZJ80L-GNPGKA that I am wanting to swap in a LS3....does this frame work? Do you have an itemized list of items necessary to complete the swap....harnesses, CAM upgrades, Motor Mount adjustments, ReUse Toyota Transmission? Any advice would be appreciated. Thanks in advance
