Coilpacked 1FZ-FE and H151F Swap

[FloridaFJ80]

Been a productive week. Got the head back from the machine shop. They decked, vacuum and pressure tested the head and also replaced all the valve seals. I went ahead and replaced the brake pedal with the manual one. I am dreading doing the clutch pedal its so uncomfortable. I also removed all of my interior seating to open up more space for the transmission tunnel surgery and to run some power lines to the rear part of my dual battery install, more on this in my build thread.

I also received my 160amp rebuilt Sequoia Alternator and the @Photoman 1FZ bracket. Like always a top notch kit. I also replaced the the Oil pump cover gasket.. Man what a breeze it is to do this out of the truck. Also installed the torx upgraded T30 screws from phhkit.com.

Today I received a care package from Japan Toyota..

The air intake hose of the 105 is a beast.. I hope I can make it work with the stock airbox. Also got my shifter console and shifter cover. Got to paint the console oak.

Hey Frank,

What is the reason you had to source your parts from two diff countries? Japan market didn't have the coil pack engines so no parts for them, is that the reason? I thought since all parts are made in Japan, regardless of what was on the road, I *assumed* that all parts can be ordered from Japan.

Only reason was that most parts were cheaper in UAE than in Japan. And some werent available in UAE so Japan was the only option.

What paint are you using for the center console? i was looking at the grey ones but the color...

I will be using the oak color. I have a special spray can with the mix. Rustoleum has a paint can called Bronze. Matches perfectly the oak interior.

So this week I put most of the engine back together and I started focusing on the wiring diagram. I will dive deeper into this as I get there, For now I was just trying to see what drives this engine and how is everything connected. When I bought my engine I also bought a complete 105 series vehicle harness. My engine came with the engine harness and the power harness (batts, fusible link, alternator, starter). While looking at the 105 diagram I noticed an immobilizer ECU that I had no idea existed. Well I have finally sourced the immoblizer parts I needed in VZ (thanks @burbuja96) which is pretty cool. My vehicle harness has the connector for the ECU so I will have to cut that out and install in to my harness.

Apparently they are all the same cams for the 105 1FZ

105 Series
Intake: 13501-66030
Exhaust: 13502-66020

US Spec 80 Series
Intake: 13501-66020
Exhaust: 13502-66010

I will be reusing the metal air box.

Old thread but hoping you are still there.
Looking for cam (and any other possible) specs for 105 1FZ FE. And cam for 80 1FZ FE.
The specs above don't make sense as cam specs.
Also, know where I can find a complete 105 1FZ for rebuild?
Thanks

The above are the part numbers for the cams. Maybe @Bardiya can she light on the cams specs.

I can help you source a 105 1FZ either in AU or VZ.

Thanks for responding. I just purchased an 1fz Fe and drivetrain and will build that first. I have a thread "1FZ engine building and blueprinting". I wish I had known about the 150 earlier. Do you think everything (head, intake etc) would fit the 1997 block. After I benchmark my build I would like next mod to be the 150 parts, without the block if it all fita.
Thanks

The head will bolt up to your block, there are a series of different gaskets that you will need, you would need a complete intake plenum with throttle body as well plus a 105 harness. I am still into my build but will know more in the next few weeks.

If I just used all the hardware (head, manifolds, etc) why would you need the harness? I assume it would be only because you would need 150 ecru to run the new ignition system and possibly fuel control?
Any way just to run just the head and intake? .
How much do you think it would cost to import the whole lot (engine, harness, Ecu), would it hook up to the 80 automatic (not sure which one 105 uses) and control trans properly? Would all the dash wiring be the same and work?

 

[scottryana]

Just a heads up a 150 is a GX/4Runner, a 105 is a solid axle 100 series with a 1FZ.

You can not run the 105 head as it does not have a hole for a distributor. You have to run COP ignition.

Oh well go with USA 1fz this time. Maybe next project

Just came back to this tjread to catch up and saw your post. This is a bit of a hijack so I will keep it short. On our US 1fz-fe heads, you can see the boss cast in for the mechanical fuel pump (for carbed engines available outside the US). This makes me wonder if the casting for the distributor is there too on the 105 head- only needing opening up and machine work to retro fit on a US engine. This may be desirable to get the better chamber design but also keep it simple and bolt up all other parts you had before. Poor man's upgrade lets say. Thoughts?

And Frank, how's it coming along?

 

[thetoyotaman]

If the cams are improved I wonder if this would be a nice upgrade and work for the 97? I like the idea of the whole coil on plug upgrade too.

 

[scottryana]

Well it is not as easy as just swapping the head. You have a completely different ignition. The GEN2 1FZ has a crank position sensor. The ECU would have to be swapped and who knows what else would have to be swapped once you plug in the new ECU, even if you found a way to supply the correct crank position signal.

This could be an option for those who are ok going to a stand alone ECU, as almost all of those things can be managed by the stand alone, but if you want it to be all Toyota, I would say your best bet is to do like OP and get an entire engine, ECU and loom.

 

[dogfishlake]

My question refers to finishing the machine work where the distrubutor mount area is most likely cast in the head, then going back to the original ignition system. There may be other hurdles, but I haven't seen one to know. My idea comes from noticing on our US heads that the mechanical fuel pump mount is unused but it is cast in anyway, making the head useable for many markets

 

[scottryana]

Yeah sorry I wasn't replying to TheToyotaMan.

I thought the same thing, could I just have the hole bored for the distributor? But I do believe the intake ports are not the same so then you need to switch the intake manifolds. Is the throttle body the same? Is the TPS sensor the same? Etc. I think it's kind of a rabbit hole especially since you would have to import it anyways.

The better idea in my opinion is to let a shop CNC port one of our heads save the program and then each consecutive head you just pay to have them run the machine lol.
