1HD-FTE Info / Opinions / Advice Requested (tech chit-chat as well)

[wardharris]

Need some help. What you know, what you think, what you suggest. Especially folks from AUS/UK.

I own a very low miles/km 1HD-FTE imported by Marv Spector some years ago. Sourced from a Toyota breaker/salvage yard in Japan, likely out of a factory test HDJ100 prior to release of that model. The motor is super clean and complete. It presents as new, having been stored by a detail-oriented engineer owner.

Considering an install in a suitable recipient, probably a 7X of some sort. I understand the differences between motors thanks to Tor, Yan and Wayne. There are several swaps documented on MUD and I understand much of what is needed to make this work - lots of sensors and work-arounds to deal with a factory ECM not open to "reprogramming" to deal with security fob, auto trans, etc. (I will use an H55F).

Here are some questions to kick it off:

1. Any other 1HD-FTE swaps out there, into non-original bodies?
2. What issues did you run into?
3. Did you use intercooler, piggy-back chip, etc?
4. What results?
5. Did you use the 100 ECM/harness or 78/79 ECM/harness?
6. Keep or toss EGR? Heater screen? Shut down flapper?
7. Upgraded turbo?

As a North American resident, Australian and UK used parts are not readily available, as with Toyota mechanics with experience on these motors.

Experience, insight and wise counsel much appreciated.

I came across a couple manuals that talk about the injection system on that engine. Not sure if it would be helpful as you figure things out, but look at Chapter 3 is this manual: http://www.steldiesel.ru/files/tnvddenso-s-klap.pdf I think this injection pump overhaul manual may apply too: http://www.kovsh.com/media/library/230/V 4 EECD0001.pdf

GT - Awesome, many thanks. I'll buy the brewed beverages....

This bloke put one into a early 80 series with a modified ute loom from killer kustom cables.

Most of those of those who do this swap in oz use a 1HD FT pump and lose the electronics and probably sacrifice some power.Although there is probably some tuning tricks to to make up for it.
The problem is 1HD FT pumps are probably less common than 1HD FTE pumps.

You're welcome! I assume you've found the manual for the 1hd-fte also? If not, here it is: http://www.toyota4wd.dk/Teknik/RM617E/RM617E.pdf Lots of other great manuals on the Danish cruiser site there too.

Got it now, thanks. Still looking for specifics on the HDJ79 version - most of what I have found has been for the HDJ100 from a few years earlier.

 

[ForealBoreal]

you can tune up any 1hd-t pump to specs

Greame (sp) (gbentink on mud) of Gturbo may be of assistance.... I believe he has a hdfte in his personal vehicle that was a transplant....

 

[CycloSteve]

Subscribed and interested to see how the thread goes. Have a 1HD-FT going into my 45, but would definitely go with the FTE if I could find one for the 80.

Don't lose the electronic pump, it's a gem and big backwards step to fit a VE instead. One of many reasons is the higher injection pressure.

I do heaps of these engines, leave it as it is electronically. Use all the std sensors as there aren't many anyway. The pump is super simple for an electronic engine and is insanely reliable. I would drive one in the most remote locations imaginable.

If you can, for simplicity, use the HDJ79R wiring harness. The reason is simply that there isn't any security on the ecu, so you don't require the original key.

But, it's not that hard to use the HDJ100R ecu and reprogram a new master key. We recently did 3 1HDFTE swaps that required this since we didn't have the key.

So, either way, do yourself a favour and make it work like it was intended.

I installed a Bad Boy kit specific to the 1HDFTE (turbo, chip, injectors, shift kit for auto) this week on one that was untouched at 507,000kms. 5 speed auto, oil every 5000km, filter every 10,000.

This car drives like you would expect for 100,000kms! We did the install, decoked the in intake manifold, blanked off the egr, serviced the trans, road tuned, it's awesome! As many of these engines as I've been involved in, I'm often in awe of just how robust they are. Plus they are quiet (not by current stds but still pretty quiet and smooth) and economical.

Anyway, you'll love the 1HDFTE, it's just an awesome engine.

If you want a 1HD-FT, by one.

There is very little difference between the 1HD-FTE and 1HD-FT. Certainly not enough that would make me consider converting the electronic version to mechanical only because I wanted a mechanical only engine.

One good thing about the 1HD-FT is that it has 10 degrees more exhaust cam duration, which is quite a decent increase allowing better boost response and more top end power potential.

 

[58bernie]

Mate, why did you tell me that, sigh, They should be interchangeable yeah.

Graeme -
Thanks for your comments above and prior email response to a US newby. Not a lot of FTEs over here and resources scarce. The motor will probably go into a BJ73 in front of a 5 speed, so the 79 ECM makes sense from a couple of perspectives - security and transmission related issues.

Couple of follow-up questions on the comments below - I am looking for durability, drivability and economy more than hot rod power and budget is an issue:
1. How "bad" is the OEM FTE turbo compared to your Bad Boy?
2. What benefits to injector replacement?
3. The chip - will it recognize / adjust for an IC on board and also address response time due to (I assume) emission driven changes to camshaft exhaust duration?

Gratefully yours,

W

Steve -

I know of your build - Georg and Don did awesome work on my 62 and I miss those guys.

Looking forward to sharing some good news on the 1HD-FTE some day. Movin' slow....

Hi Ward,

Ok, I've never actually had the need to change the exhaust cam, I just offered it as a potential mod. Downside is slightly lower efficiency of engine in main area of operation (1600-2200rpm).

The factory turbo is fine as it is depending on what power level your looking for; you can just add a cheap chip like "chip-express" on the std engine for a nice genuine 20% increase in performance. About 5 years ago I did just this. I still have the chip actually because I didn't feel comfortable about selling such a basic dumb chip, but at the time I thought it was great.

Now though, knowing 60% increase is really easy and even 100% is easy and reliable with even better economy than std? It's not really an option anymore.

What exactly that chip do ..? I mean boost, fuel, timing .:?

 

[wardharris]

As I understand it:
Pressure
Timing
Boost

But I don't know what I'm doing....

What exactly that chip do ..? I mean boost, fuel, timing .:?

Fuel, period. Very simple too - no boost or throttle reference. Only connects to fuel valve on injector pump and battery. No other inputs. Adds fuel as a percentage increase, so simply richens up the engine exactly like turning the main fuel screw on your 1HDT and not adjusting anything else (like boost compensator)

That's why I don't use it. When I bought it i knew not what I was doing

 

[wardharris]

Fuel, period.

I don't know what I'm doing....

Thanks for the clarification, Graeme. My understanding regarding other functions was drawn from other websites, publications and marketing materials.
