I6 Landcruiser intake mods

OM,
I think that your thinking of a different motor! The 1FZ-FE seems to be built like a brick Sh*t house... 7 mains, forged crank and rods, and oil squirters for piston cooling in a naturally aspirated config... Im liking them.

I was referring to the older engine, the F and 2F. I remember what a pain in the ass it was grinding the mains on those multi-size pos because you have to set the arnold guage for each one. Its the same on the 235 Chevy's, I guess they thought getting larger as you go back would make the crank stronger. Also 4 cyl Peugeot cranks but the mains got smaller as you went towards the flywheel flange just the opposite of what you would think.

OM,
Kinda like left handed lug nuts...interesting ideas that just caused problems.

The Header and the full 3" system I have on mine you can get "off the shelf" here.

The good thing about the whole system is that it bolts together on the original locations, so you can just add the header or the two parts of the 3" system.

The motors as you can see are bullet proof and very under stressed in standard form.
They are very reliable and work well in tough conditions doing 4X4 off-road and very rarely let people down.

The bottom end of mine, to the best of my knowledge, has over 300,000 miles on it and is still solid.

When I first got mine I thought, this thing needs cam, and then went about looking into cams for it, not long after I had the 600rpm experince and from then on I was not going to change cams!
But saying that I think cams would really wake up this motor with its four valves.

Then there is always this option that's popular over here, around $4000, this one is on a 100 series.

Since we were rushed on this project (3 weeks from phone call to delivery!) we were not able to deal with the air cleaner element design very well. The kid that works for us tagged the element spacers to try to hide the ugliness... dont think it worked. The rest of the system came out nicely, but we had to create a linkage that would reverse rotate one of the bodys to get the factory Toyota TPS going in the right direction. I found a different element from K&N this morning that will work out much better in the future. Im hoping the bottom end is big with this system, but who knows...Its all show at this point.
Next!

Why not just change the pinout of the TPS sensor so it responds with correct open/close voltage without having to reverse the TB direction?

Otherwise that setup looks pretty awesome to me.

DG,
The "users" are running the stock ECU and the Toyota TPS is a 4 wire with a idle "on" switch... couldnt find a toyota 4 wire TPS that rotated in the other direction (mechanical issue)..I think I found a Mitsu unit that would work, but I ran out of time. I also needed the 6 wire single pole Toyota IAC unit but at 400.00 a pop I demured and gave them a 4 wire unit and my best wishes. They squeezed me both on time frame and cost...Im supposed to make more of these for these guys so hopefully I can upgrade the prototype as we go along.

What I was suggesting was, let the TPS rotate in the wrong direction, you can re-wire it so that it still reads increasing voltage with increasing RPM. But if it was a physical problem, then I understand.

Still, what you consider "quickie work" most of us (me included) consider "masterpiece"

DG,
Why thank you!

Pretty unique setup? How long are those runners?
