Swapping a 1HZ for a EFI or EDI 1HD-FTE

lot lot cheaper to just get an aftermarket turbo fitted.

would'nt be lot, meaning difference in power etc, in it would there?

Hi Jason,

On the 100 series manual 1HZ, the gearbox is the "Prado" 5 speed (R151 I think), unlike the H151(?) on the 1HD-FTE 100 series.

Upshot of this is that the factory turbos have a much stronger box than the 1HZ diesels. So even if you manage to overcome all the electronic issues with the wiring harnass of a 1HD-FTE it still leaves you with a "weak" gearbox compared to the factory turbo.

The cynic in me reckons Toyota did this to make aftermarket turboing of the 100 series 1HZ less atractive, all 80 series diesels had the heavy duty 5 speed gearbox regardles if turbo or not.

Cheers

Thought about this myself, the 79 series ute has the live axel and turbo motor, so it should work in theory. But you would need the bigger gear box. If you eventually get an answer and can do the swap, well what a 4wd, comfort power and reliabilitiy. Talk to a conversion company for example IFS to Live Axel etc, they maybee able to help. for example it may be easier to remove the IFS than to swap the motor. Don't know for sure but worth a try.

Id reckon go with after market turbo on what you got like "member no1" said at least you know how yours has been treated, if gear box gives you any trouble in the long run then worry about it, mate has turbo'd his had 40k on it when he bought it now has just over 100k (his is only the base model barn doors on the back) and no trouble so far,Doesnt tow a camper or any thing so maybe that might be an issue if towing gearbox wise. I think it would be a big job with all the wiring harness's sensors, etc. Just my opinion only. Regards Steve M

I think the 7x series always have the heavier box for each variant.
There are a few that I know of that have done it with the earlier turbo's.
If going the later electronic route you would be best to get a whole donor vehicle to ensure all the necessary wiring and black boxes are obtained as well.

I spoke with one of the 4wd wreckers in Brisbane about it a while ago, 10k for the engine, 4k to fit with a 5 speed auto included.

Thanks too all who responded, I would like any other details in regards to wreckers names, numbers and stuff like that, as I am based in W.A's north.

It would be far far far far cheaper to sell your vehicle and buy the factory turbo. You will also keep the skin on your knuckles.

Of course it is a different story if your motor is fu*$ed and you need to replace it anyway.

Hi Jason, Give Matt a ring at Perth 4WD Centre. 87 Kew Street Welshpool.
ph 94701755 or web www.perth4wd.com.au
he imports half cuts of 4wd, give him a call and order a half cut that way you get everything you need.
Hope this helps.

Hello Jason,
My mate owns a 1HZ engined Troopy and I own a 1HD-FTE engined Troopy.
We parked them side by side one day and compared what would be involved in putting the 1HD-FTE into his Troopy.
Short answer, sheite loads!

Long answer, the whole wiring harness is just totally different. Fuel system is different in and around the engine bay.
There are a heap of electronic modules in the 1HD-FTE that just plain don't exist on the 1HZ. Even to the point where the 1HZ has a cable throttle and the 1HD-FTE is fly by wire.

By all means look into it, just be aware the differences are far more than the engine and gearbox.

Your easier option may be to slip a 1HD-FT (mechanical injection) rather than 1HD-FTE. And if you were to start with an auto GXL 100series, it may overcome the weak gearbox and clutch issue.

This gets discussed a fair bit on the LCOOL groups.

And converting an IFS to rigid may be difficult because of the different chassis widths.
