v8 tacoma

you wouldn't happen to have any of the wiring diagrams for the 1gr or an 06 4runner 2uz would you

 

So best bet would be a complete engine and transmission transplant?

 

I've read that the locking function in the torque converter may be different and plan on using the donor, 99% sure the donor 4runner transmission is the A750 5speed though (havent crawled under there to verify) but with an AWD xfer case. Hoping to use donor motor, donor torque converter, Taco tranny, taco xfer case. Also have all the appropriate controls and harnesses in the donor 4runner

 

Nope, 03 & 04 V8 4Runner (and Tundra) use the same trans as the 03 & 04 3.4L V6 Taco so that won't pan out for you

 

Easier

 

Not true my dads 2003 v8 4runner has a A750

 

Yes, just confirmed A750F on mine. Still wonder what the VVT/NON-VVT difference will be.

 

Sorry, bad research I guess. Glad I'm wrong then

 

I'm gonna guess immobilizer would be the biggest hurdle. Engine power output is the same

 

Torque is the same. Horsepower is a lot higher with vvti

 

If he is talking about his donor runner it's a non vvti with a A750

05 vvti had the most HP

 

05-09 are the same. I know what you mean about 05 having the most power but that's only because they change the way they rate it nothing else

 

Not 100% true I've felt and seen the difference, I've had my dads runner (03) a 2005 tundra (4door) and a 2006 tundra (4door) stock for stock the 2005 won every time

 

Now that's some science lol.

 

Its cause toyota wasnt going by sae correction when they advertised hp and tq numbers in 2005.
2006 model year is the same truck, just sae corrected numbers like the rest of the world.

 

Sooo did this ever happen? The 5.7L I mean ... What if someone had like the whole thing engine trans wire harness computer, the works. It would still be a challenge but then wouldn't you only have to get the Tacoma gauges to work with the V8

 

@jberry813 attempted to put that motor in a third gen Taco. Probably gave up though cuz that thread is gone

 

God I'd love a 4.7 in my Tacoma. Sorry 4.0, but those things sound sweet and pull hard.

 

hey guys, so i have an '08 tacoma 4WD, have plans of swapping my half-working 1GR for a 2UZ as its gonna be cheaper buying the 2UZ engine ecu and harness, just wondering if someone could let me know if there's anything else i'd need, i plan on using the 2005 tundra 4.7 2uz, also i have the a750 5 speed automatic transmission, i was told that the tranny fits right up with the 2uz engine, just let me know if i'm wrong and what else i'd need before i get the ball rolling on this project, most likely gonna go ahead with it anyway but it would just help if i had an idea of how much more work/money i'm gonna have to put in,

note the 1gr engine is costing me 4k and the 2UZ with ecu and harness are costing me 2k so i'm looking at the savings there.

 

You need the radiator and fan shroud and bell housing/torque converter from the V8 and depending on what you decide regarding motor and transmission mounts need to figure out drive shaft lengths.

And make a thread here on the project. Lots of guys will want to see that
