No one builds the trans, the guys that say they do won't actually tell you what they do, and I bet it is just a valve body and they charge you crazy money.

You could check the holley dominator if it works with the 1FZ-FE, crank and cam sensor it should be fine. Really the standalone only controls fueling and ignition. The stock computer controls everything else and feeds signal to the TCU, you could take over more with a standalone if you wanted. Would just mean more wiring.

7.5cr is overkill and silly on this motor. It is 9:1 stock, if your goal is 500awhp you don't need to touch the bottom end except for headgasket and studs.

Save your money from forged pistons and buy a better turbo and engine management. also are you going to cut up the front end for a big air to air intercooler? If so save your money from the Pistons and rods and get a high quality core. Bell or Garrett
 
Thanks for the info, All Ive been able to find is an after market VB. I guess billet input or output shafts, billet converters or upgraded clutch packs dont exist for this A343F... Is there a standard transmission that is popular for swap in the FZJ80? How many people go to manual transmissions?

Yes I will be picking up a decent intercooler for this turbo build. Any of you guys have any input on turbo sizing? T3 looks like the standard size most 1FZ builds ive seen online use... then again most of them are only making 300-320 whp... I havnt seen many 500+ hp 1FZ builds or maybe im not looking in the right place.... Also, id like to have good low end torque so something that can spool up at lower RPM would be nice... I imagine a compound turbo setup would be way overkill.
 
Yeah that is part of the reason I believe the shops selling the expensive transmissions are full of s***. There are no parts to build them stronger and not a single one would tell me what they did to make them "handle more power" smoke and mirrors.

There are no real popular manual conversions, it can be done with a H151 but it isn't popular because of scarcity.

Not sure where you are seeing all of the turbo 1FZFE builds but I don't know of anyone using a T3. A T3 would be under gassed for a 4.5L 6000rpm motor, usually. You will want a T4 divided, twin scroll, since the stock exhaust manifolds are already divided into the correct sequence for twin scroll. And remember 500awhp will be 700+hp at the crank with drivetrain loss so the smallest turbos you should be looking at are:

Borg Warner
EFR 8274(small) or EFR 9180(large)
max flow 79lb/min and 95lbs/min respectively

Precision
PT6766
max flow about 93lbs/min Precision doesn't give compressor maps

Garrett
GTX3582(small) or GTX4088(large)
max flow 78lbs/min and 93lbs/min respectively

The smaller size will spool earlier but might not quite meet your 500awhp goal, but should be close the large size will easily meet your goal.

I guess Ill have to be happy with a valve body only... I dont even see any upgraded TC's which seems odd... One would think there would be a market.

I was reading turbo builds using the GT35r Turbo which I assumed to be a t3. Also I was looking at "safari" turbo kits used frequently by some on these boards... I guess most of those turbo kits were seeing about 300-320hp... I thought about utilizing a compound setup where I can use a small turbo to spool the bigger turbo... It may be overkill but my old dodge cummins really ran nice when I put my stock turbo over an S475. it spooled up really low into the rpms and the big guy really fed it some air up high.


Also, has anyone see the Wolf ECU kits? they are plug and play, and also control the transmission! http://www.wolfmotorsport.com.au/plug-in-kits/toyota/toy40.html

Wolf V550 Toyota Land Cruiser 80 series auto Auto Plug- In allows for removal of the original ECU and the Wolf to be fitted with minimum effort. This uses the standard sensors of the vehicle with no modification required.
The dashboard and controls all remain as standard in correct OEM function. This allows tune-ability of up to 30 psi (45 psi if requested). The tuning is 125 rpm over 16 load points. This is for both fuel and ignition. This allows for turbo charging or supercharging of your vehicle if requested. One of the benefits of having the V550 is that you can have all of the auxiliary inputs and outputs. This allows for different idle speed requirements for when winches are being used or excessive headlight battery drain is used we can step the idle on.
Talk to us about your requirements with this system and we can tell you the benefits of it.

NB: Due to its complexity we recommend that you enlist a trained Wolf Dealer set the transmission to ensure you get the most out of your engine.


The kit contains:

1 Wolf V550 Toyota Land Cruiser 80 series auto ECU
1 Toyota Starlet Adapter Harness
1 PC Software Cable
1 Software
 
Safari's kits were no where near 500awhp, and a GT35 is its own size. T3 and T4 turbo's existed before the GT28/30/35/40 designation. The only take away is flange size. Trust me you will want a T4 flange on a turbo sized to make 700+ hp.

Yeah compound not really necessary. On a diesel you were probably running 40psi you will be no where near that on the 1FZFE. If to ran that much boost you could make 1000awhp. Lol

Good luck finding a wolf dealer. I would stay with the big name brands, so if you have issues or questions you can find someone to help you.
 
also I found this in regards to the trans, although it doesnt spell out the A343F

Yeah smoke and mirrors, I called them and they were clueless on the A343, they were like Yeah go ahead and send it on in and we will take it apart and see what we can do. But if you read that list the parts aren't available for the A343 and several of them are addressed by simply doing the shift kit. Like :

Performance pressure regulator boost valve is installed to increase clutch holding ability.

The shift kit increases the pressure regulator already.

Like I said you can send your trans to them pay ridiculous money, get a product that is suspect, because there are not Reybesto clutches for the A343 or you can just have yours rebuilt with good parts and do the valve body and save yourself thousands.

That was mostly written for the supra transmission. I took my transmission to Boost Logic who has many 8 and 9 second 1200+hp supras and had their trans guy break mine apart and look at it and he said stock with shift kit should be good for 800hp.
 
Ya I noticed there is almost no info out for the wolf ecu... Boy it sure does sound nice though, not to have to splice into the factory ecu harness.... not to mention the trial and error/fixes of removing all of the egr and emissions crap then having my factory ecu go into limp mode due to the cel triggering...

What do you recommend for fueling mods to feed the bigger injectors?
 
Wow! Thread revival.

On this topic though, I'm planning a turbo 80 build in the medium term and it will be getting a haltech and compushift combo.

Not a fan of a unichip in this application (they get good results in modern turbo diesel applications but don't give the control like a full ECU gives) and Wolf's technical support isn't like Haltech where you can ring up and speak to someone who knows what they're talking about. Haltech now make a plug and play for the 80 and Wholesale automatics sell a harness to make the haltech talk to the compushift.
