1HD-FTE Conversion - Creating the Perfect 80 Series (8 Viewers)

[TheBussman]

Pretty sure baldur's control systems DSL1 could run the engine and maybe better then the factory one. Although it would need quite alot of tuning to get it going he does not have a base tune for this engine. He can remote in and help you tune for a fee. Also has a transmission controller if you can't get the stock one working. might simplify wiring a little too. i would ask him about it if i was going to do an FTE swap.

@SteelHunterFJ80 I'm still going back and forth on it. I don't have a manual trans vehicle any more and miss it. Would be super cool in an 80.

Also, a year ago when I thought I was going to be a reasonable person and leave the engine in the 80 as it is, I regeared the diffs to 4.56's. Made a nice difference with the heavy tires, but i fear swapping in a h151f (not to mention sourcing it) would spin the FTE quite a bit on the highway when hauling some a$$.

I suppose i could always overdrive the hi-range in the t-case, re-gear the diffs again, or simply get larger tires.

I threw this together a while back when kicking around some ideas:

Curious, what diff ratios are you running and tire size? What's your engine speed when clocking 80 mph down the highway?

I also wonder if 2630rpm in 5th @ 80 mph with the auto 5 speed is a bit overboard since the FTE should be into the torque by say, 2k rpm.

I'm on 4.10 gearing with just under 33s and running 75 mph at about 2900 rpm with an h151 and the FT. Although next month I'm going up to true 35s.

I can't say this enough but there is zero chance that I would ever run an auto. Just the power loss and selectability when wanting to add power or use the power band more efficiently is more than enough reason to do the manual. Add in a part time transfer and it's perfect IMHO.

lay down the complete wiring you got and show us a picture..

I can help you with the wiring, no need to buy - plus, there is going to be many differences that you'll have improvise anyway.

like, the speedometer you have doesn't have the room for PRND432L.
it only shows PRND2L.

there will be too of many of such things.. so lets see what you've got, also show the ECU side plugs.. I will get you a part# too for the correct ecu

plus there is only one ECU for both the engine and transmission, if you've the complete wiring, it will be a relatively very simple job.

Totally agree with respect to what running a manual gets you. IF I can find a manual for what seams like a reasonable price I'd go for it. Any recommendations on where to source? H151F or H152 (gearing seems more ideal) would be the ticket.

I'll take you up on some guidance - I'll lay out what I do have of the harness, which is about half of it, and get some good photos. If I were to stick with the A750F auto, I'd run this clever adapter by Lutz Auto

EDIT: Do you know where I can source OEM toyota connectors and pins?

So I'm probably at a fork in the road here:
1. Decide if going manual or Auto
2. Then proceed with wiring and getting an ECU as the ECUs are auto/manual specific. Don't know much on these ECU's, but i do know this much.

Another thought. Let's say I go max depth down the rabbit hole and decide to go manual. Does anyone know of a way to retain cruise? Based on lelandEOD's conversion thread it seems the ECU also handles cruise control for the autos. Wonder if this is also true for a manual FTE ECU.

REF OEM connectors, I can find out where in the US and let you know.

I would personally just use the gear lever from the 100 series, instead of using that adapter; to me its added ****ery, given the way i use a car
CC control is the same for both manual and automatic.

While I always like an automatic in these things, the 1HDFTE with a manual is an experience of its own! Its kind of addictive too haha

 

[SteelHunterFJ80]

@MooseMichaels You will want to hunt around the various toyota dealerships. I think you can get one for around $2600 before shipping. Part number is 33030-60C51. Thats the newer model with the taller 5th gear

 

[TheBussman]

last i herd Toyota USA stopped letting people buy h152s at the local dealer last year or so.... you have to get one shipped in.

most but not all oem connectors and "repair wires" are sold at the dealer or overseas OEM parts supplier. Grab the part numbers from the wring repair manual listed in the resource section. some of the pins are for sale at ballenger motorsport.

Small update here, did the timing belt, water pump, tensioner, cam pulley and t-stat last night. She should be ready to roll.

Oh and I carved out what seems like a pound of very fine dried silt from the back of the fan pulley and from the harmonic balancer.

Next will be oil pickup and pan. Working on sourcing those now. Sounds like Dave over at japan4x4 has a hookup (thanks for the recommendation @ikarus). Need to source an EGT sensor setup, was thinking something like this. Open to suggestions if there’s other options folks have liked.

I'm a fan of the Lutz Auto multigauge. I use it for boost and EGT.

Correct, some info here:

What exactly do you tell them? Ive been to two Toyota dealers and gave them the part number and both of them said they were not able to get it and that it was a non import part?

These transmissions have been pulled from US procurement. They are no longer available from a US Toyota dealership. Toyota has pulled the plug on these no matter what documentation you provide them.

They can still be procured from overseas sources within 10-15 days.

So here's where I need some information and help as well, I have an 1hdfte auto 4 speed ECU.

Im leaning towards the h152f, Ive asked Mick the guy making my harness if running the manual on the auto ecu is possible, he's said its perfect, and didn't really add anything else to that.

Anyone have experience running an auto ecu with a manual setup? Im assuming itll probably throw some kind of engine light since itll be looking for auto transmission inputs that arent there.

I know that this doesn't really help but I've done it on an MR2 and it was fine. I would think it would be fine on your project but just throw a bunch of fault codes.

for gauges I've used both UT comp and Lutz in 80s

they are both good

lutz is very easy, very simple to install. the cleanest option.

UT comp is much more complicated, adds a box under your kick panel takes about 3x longer to install/setup, instructions are not that clear, but has some advantages: you can connect even more inputs if you want to. You can customize just about anything. You can use almost any sensor and calibrate it to work. You can use it to control an output power like for a fan, water meth injection or in my case an air to water intercooler pump. Paired with the trail teq enclosure its still a pretty clean install on the steering column. It can also be used in any car not just 95-97 80s

There was some discussion in this post and a few after it on fooling the 1FZ ecu. The 1HD isn't necessarily the same, but it wouldn't surprise me if it was.

Post in thread '1FZ trans swaps 6R80 10R80 and more'

Jun 18, 2024

I looked into fooling the ECU into thinking the stock transmission was in place, even though it is no longer there. The best I came up with was to put fake inputs to the ECU to think the trans was there and in Neutral or Low. To do this I think you need:

• 12 Ohm, 20 watt Power resistors to ground on ECU pins 8, 9 and 10 in place of the shift solenoids. I doubt the ECU will do more than verify the resistance since it will believe the trans is in P the whole time, but if it sends a signal to any of them, they will get warm.
• A resistor on ECU Pin 12 to simulate the A/T fluid temp...
