Very nice write up and some very clever and effective work. I don't want to know how many hours this will take to finish....
Good luck!

I love it! There is a serious amount of ingenuity here: Do what you want, and make it work.

I look forward to more updates.

How are you making the F40 work with the Toyota master cylinder and shifter cables?

Also, how are you getting around the axle-subframe clearance issues? mainly the left axle tulip hitting the lower control arm.

Here is an adapter for the oil filter if you want to do something nice and tidy in there and add other things, like oil coolers or an accusump.

Great job btw. I am impressed. You are in inspiration to all of us fabrication guys out there.

Also, I believe the 3mz coil on plug should be a direct bolt on replacement. You could use them and they have the ignitor built is to make it a very easy install.

Lil confused.
1st let me say that I am not being negative or bashing. I love the work you are doing as well as your balls and skill. You commented that the ecu was fine when new but better ones are out there now. Agreed. The engine is also outdated. The are V6s out now, 2gr, that make more power and probably as much torque. Why go the 1uz route? Its big heavy and doesnt make that much power by todays standards. Keep in mind that I want to bud a 4agte instead of going more modern.

3mz, 1gr, 2zz ignition coils are all pretty similar. I made a video on youtube with some measurements. I kind of went back and forth with inches and metric because I like metric better, but most of my crap is inches.

I agree that a 2gr is an amazing motor, but I think there is untapped potential in the 1uz and sound of a V8 back can be worth it on that alone. As I see it is basically a 1mz block and heads with 2 more cylinders. They have almost identical cam specs and compression ratios. They both are pig rich under WOT. The 1uz they have done over and over again cams and have gone shimless buckets like the v6 and even 3sgte guys. The engine is just so overbuild and only 4.0L that they throw some twin turbos on them and call it a day.

I see a few major limitation to the 1uz though as it was designed for a heavy automatic car to run to maybe 5500 rpm in the real world applications. It is about 20-25% heavier, as expected from having two more cylinders, but should make 20-25% more power. It is about 5" longer so you have to deal with the size. It makes about 165-180whp in stock form. Now this makes sense is the 1mz makes around 160whp with a manual trans and better intake manifold. Also the 1uz you almost always see is mated to an automatic trans that is garbage and sucks down an amazing amount of power. I have seen dynos of 225 range with an automatic trans with headers and free flowing exhaust and air filter mods and with cams it makes about 30 more hp. The rev limit is limited to 6500, but can be revved to 7000+ all day with the head design and stock valves, springs and retainers. Also if you build up with valve springs and shimless buckets then 8-9K and fun.

So here are some solutions to the lack of hp.
1- Mate that bad boy to an efficient manual trans. That should be 20-30hp right there.
2- Exhaust header and complete system in the 1uzfe stock form is a joke and really bad. Open it up, make a nice free flowing 4-1 exhaust and let it flow. There is a bunch of hp there. The 1uz guys say 25-40hp on that alone assuming no cats and a good flowing muffler.
3- Get rid of all the extra pulleys and pumps that thing has on it. That should help and a bunch and get a lightweight pulley. Maybe 10-15hp right there. They have the fans run off a pump.
4- Air fliter, the stock is fine, just have to let it breath a bunch better. They say 5-10 hp there.
5- Tune the AFR with an AFPR to around 13.5 instead of 10.5. Now that is a good 10-20 hp there.
6-Biggest issue is with the intake manifold. That is holding back a good 30-40hp and any hope for hp past 5300rpm. The design is junk. It does not have smooth flowing lower ports at all, goes from a circle to an oval to tapered to 90 degree curves multiple times. It is made to only rev in the low rpm range. If you give this up you can rev the engine much higher and make a bunch more hp up high so the number will be higher, but the usable range of power should be much great. If you can make a custom intake or figure something out there that is hp.
7- Get a set of reground cams with some lash caps and go from 224 duration and .301" lift to 274 with .385" lift. This is around 15-30 hp.

Now if you start out with around 170hp and do the mods before the intake and cam you are around 240-260rwhp, which sounds about right. With a good designed intake you should be close to 300rwhp and if you put some cams in it then maybe 315rwhp.

There you have it. I would bet if you do those things you should have well over 300rwhp and tq for a nice wide rpm range and have that sound past 7000rpm. Now that would be fun. I also do not think you need to go stand alone with an NA engine as there are things that you can do to make it work, but would be band aids for sure. I am think that to keep the cost down since the 1uz is dirt dirt cheap. I am not sure what can be done about the timing to advance it as I read that the guys would like about 6 degrees more timing. It has two distributors so maybe the holes or something can be ovaled out or slotted to twist it or something. If you can adjust fuel with an AFPR and be missing only 6 degrees of timing I am thinking that is good as the cost of the stand alone to me would not justify the gain in hp at that point.

Plus, the sound of a v8 screaming behind you, oh the fun. Then the innovation to do this is worth it. I applaud you Ferral and keep up the good work. Now get back to work as I need some updated pictures of this beast.

Back in the mid 90s actor Craig T Nelson was using a 1uz in his open cockpit sports racer. His people couldnt believe how overbuilt and under stressed the 1uz was. Especially the early ones. They did have trouble getting over the 600hp mark in n/a form. They eventually switched to a different engine. I dont recall what they ended up using in later seasons. you of course can twin turbo the 1uz and make stupid power but how much can you actually put to the ground even in a MK2 especially with the torque it would make. I remember seeing a story in Sport Compact Car I believe about a twin turbo Lexus SC400. The 1st gen SC. Owner was making 700+ hp with his.

I haven't mess whit the Toyota shifter cables yet, they need to be custom I believe, Am not sure if the Toyota shifter is up to the task , the Fiero shifter its proven to work, I may used if the Toyota don't work,

the only clearance issues I encounter on the left side tulip. the cross member need it some grinding nothing mayor

This is amazing work! I'd be interested in a flywheel if you're willing to part with one.
