What are you running for an ECU ? I had a Microtech, aussie company, ecu comes stock with dual ignitor channels.

I had a hilux (tacoma sized) 4x4 with one years back, went like a cut cat, all the way through to 10,000 if you let it. Another common mod in NZ is sticking an extra throttle body on the intake, the factory plenum chamber is known to be restrictive. Heres my old engine.



Cool project good luck with the swap.

Thank you

I'm running a Wolf V500 (also aussie company) with a coil on plug conversion.
I ran this engine in my truck for 2 weeks with the stock ecu, (sadly in limp mode, cut to many wires) went faster then my friends 03 silverado. The limiting factor is the th350. 3 gears is just not enough, but converting my truck to manual is not really in the books for me, I'm too tall and the seating position does not feel right. So I'm looking for a 6 speed auto. Hard to find.
As for the restrictive plenum, nothing a little forced induction can't fix.

That hilux must haved moved with a bit of speed.

The the hilux was a weapon. In my c10 Ive got a toyota a340LE auto (or A30-40 sometimes), manually shifted with solenoids and relays, but its only 3 speed with o/d.
Its the box they use behind the supras, jeep cherokees etc, might be worth a look ? I think theres a conventional (fluid shift) one they use in the newer hiluxs here that might be 5 or 6 speed.

I had a 5 speed in the hilux and it was too much, with tall gearing it had major traction issues. With that intake and ecu we dyno'ed mine at just over 350hp at the flywheel and I never opened the engine.

You probably know already but these engines have a very narrow torque producing band, I think its 1500 rpm or so either side of 4000, so I can see why you'd go for more gears to make use of that.

The 1uz came with the a340 transmission, but it was seized from sitting for 6 years.
The trasnmissions Im curently looking at are the new 6L80/6L90 from gm or the ZF 6HP26 from a bmw and many others. Both are fully electronic transmissions. So I'm waiting on a custom control modual. Almost equal gearing in both transmissions.

Gear ratios:

1 ......... 2 ......... 3 ......... 4 ......... 5 ......... 6 ......... R
4.17:1 .. 2.34:1 .. 1.52:1 .. 1.14:1 .. 0.87:1 .. 0.69:1 .. 3.40:1

Any pictures of the swap in the truck? I'd like to see that.

[canadian trucker]

I do not have many pictures on my work computer. But here are a few.



Tired old I6 comes out. (250 cid with a th350)





1uz-fe Lexus engine mated with my th350 using a 1" aluminum adapter and a custom torque converter pilot.





How I ran the truck for 2 weeks

I'll dig up the other pictures once I'm home.

Here are a few more pictures of the swap




The one inch adapter and custom torque converter pilot mount.




I cut out all the wiring that the engine did not need to run. (apparently only 25 wires are needed to run this engine, out of 80)




I TIG welded mounting plates for the down pipes on the exhaust. I also deleted the cat's in the process.




A gen 2 power steering pump was added, with a custom mount, the pulley is a spun down 5 liter mustang one with a custom spacer.




I also fab'd up a power steering reservoir.

Nice choice on the engine..

OK, a little update.

Went to shop yesterday to look at the progress of the truck.
(slow but perfection takes time)

The firewall and tunnel has already been cut out, to allow the engine to sit further back and lower then before.

This should allow for a better weight distribution and lower center of gravity.
Also more space was needed for the 6 speed transmission.

I am very impressed by Nate's dropmember, it enabled the engine to sit lower and closer then before, while converting it to rack and pinion steering.

My only concern at this time is that, my new exhaust manifolds for the turbo's will be to close to the frame. May have to run rear mounted turbo's.

Next time around I should be able to get pictures of me new I.R.S. setup, and the truck sitting on new rubber.

[69gmcc10]

love this idea, any progress here?

[canadian trucker]

Not too much yet, been low on funds.

Last thing that went in was a Tremec T-56.
I'll be visiting the shop after work today to take a look.

Thanks
John
