Sneak peek

where the 91-97 cylinder head has the distributor, is it just an un-drilled boss on the +98 cylinder head?

Yes, partially cast not drilled through

I have a Japanese 1fz head with the EGR port in the same condition.

Fit & Tacked. Thanks, Mike!

Coil pack heads do not have the egr drilled out either

It’s the EPA-free variant. They also don’t run an O2 sensor. (Well, not in stock form..)

Not sure how I missed this when I was at the last RS meeting held at Cruisers & Co.?!?!?! I guess I should have taken a peek around the corner to see what was in the shop.

Man I should come and visit seeing’s how I live less than 2mins from the shop

They all have at least one O2 if it’s a 1FE-FE for closed loop engine control, 1FZ-F there are none

Made strides today which is good because CM is coming

It was a little less compete last meeting

Change that “I should” to an “I will”! Door is open

I've been reading up these clutches and they're super cool that the center input is swappable for whatever input shaft you're running. I was wondering when someone would start using them in Land Cruisers.

Install of the clutch was fairly simple. Instructions could’ve been a bit more detailed but we got it done. The kit comes with some spacers and special hardware. Once the order of everything is determined then it goes on easily.

For future reference this 4Terrain setup with a 311mm PCD 1FZ flywheel used 6 mm of spacers and when done the ring will have a press fit over the clutch body and sit flush with the body of the clutch. It was a little misleading at first because the ring will not fit over there clutch body by hand but once the hardware was installed it pulled it all into place and torqued to spec nicely. Be careful when installing the center splines it does have a specific direction it needs to go. Can’t wait to see how this thing feels!

1FZ-F has a carb.

There are 1FZ-FEs that don't run an O2 sensor (or catalyst). For example in Qatar for the 80 series or most of the 105 series 1FZ-FEs, including the GCC-spec and Australian spec FZJ100 (which was the original source for the engine in this truck.) These have no catalyst and no O2/lambda sensor. Qatar only moved to unleaded gasoline after June 1, 2000. Australia didn't get rid of leaded gasoline until 2002. Running leaded gasoline will plug the catalyst.

And correct: the 1FZ-FEs that don't run an O2 sensor also don't run "closed loop". The ECU can still use inputs from the MAP, Coolant temp sensor, IAT, TPS, crank and cam position sensors, etc, along with lookup tables to determine the duty cycle and timing for the injectors. Closed loop gets you fuel trim, which improves fuel efficiency and emissions.

I'm not saying "don't add one". I added one to that exact engine to run the Haltech 750, because the stock ECU would go into alarm at 1psi of manifold pressure, and as you know, it was running a supercharger.

Learn something new everyday. Seems dumb that Toyota would develop an ecu for these that didn’t fine tune fuel via an O2/lambda sensor on an engine that already gets dismal gas mileage. I guess gas is cheap enough over there that they can waste it

Good explanation, most people don’t understand this about non-US 1FZFE’s.
