Hi
I own a 2005 hzj105r, which I am considering turbocharging. I have had experience with turbocharging a 1HZ (I had an 80 series previously) and know potential reliability issues, but I am wondering has anyone actually installed a genuine Toyota 4.5 litre turbo diesel into a 100 series.

I am not interested in a 6.5L Chev as they are too noisy, a 4.5l TD would have enough grunt and no issues with parts availability or re-sale or reliability.

Turbo intercooler kit (Self install) will cost ~$5,000, but if I could put that money together with the sale of the (25,000km old) 1HZ (~$5,000) it would hopefully cover the cost of a low km 4.5l TD from a wreck.

The question is what are the difficulties (Such as wiring harnesses, computers, clutch, engine mounts, adaptor plates? etc..etc. Does anyone know?

Regards

2D,

Assume you mean the Tojo 4.5L V8?

Think it might be too wide, around the inner guards to fit? could be some dramas with all the wiring needed too.

Would be a magic conversion, just the same,

Yeh it would be a sweet thing...

Don't know why Toyota didn't continue with the standard 100 series with the single turbo 4.5l diesel, rather than the 79 series wagon that happens to have trailer springs under the back. Have heard that some mining companies have gone back to Hilux as they have airbags which the 79 series has not.

So far as fit, I'd have to get the tape measure out, cant see it being an insurmountable problem as the 100 series had a OHC petrol V8 in it...

FWIT back about 12 months ago when I was looking into getting a 200 and there were a few rumours about the 4.5 reliability. I went to Britz head mechanic to ask about them. They had over 200 x V8 70 series at the time so should see something if it were true. He said that they had no dramas BUT they had a few roll overs from Tourists going too fast. He also said that he had a 100 series 4.2 and seriously looked at swapping the motor over from a right-off 4.5 unit as it was so sweet. He said that there was no way that he could see that it would fit and it would be a nightmare with the electronics and mounts. I guess that has something to do with the new 70 having a wider track at the front.

Its ok I've been called an FWIT before...!, er whats FWIW, I'm new to this...

It should fit the 100 series as they had a petrol 4.7 OHC V8. So far as track, I don't believe the 70 series track is wider then the 100 series.

NO..RE 4.7 OHC
Thats why the V8 where only in 100 (not live axle 105) which are IFS and also have a wider chassis to accomate the V'ee motor

Wouldnt it be a much simpler proposition to just install a 1HD-FTE?

Yes you are probably right, but wouldn't it be nice to have the V8. Its what the 100 series should have had.

yep would be lots less problems ect. And a 1HD-FTE with a zaust and chip ect will fly as good as the V8. FWIW the old mans GU with the 1HD-FTE and zaust made a V8 ute look twice to see why the patrol was still with him up the hill. Plus it is a proven motor with very high Km motors out there.

If you are in Sydney and really want to do it. Talk to Jason at total 4WD care at seven hills. He is a conversion guru.

Coupla thoughts ...........in 'low spec' form, doesn't the new V8 TD have much the same performance figures as the 1HD-FTE ? Only the "up spec" twin turbo V8 TD (as in 200's) has the super attractive numbers ...... as for the imported V8's (al la Brunswick Diesels et al)..... they have the expertise to squeeze them in and set them up of course, but looking over the figures, I couldn't quite see the advantage they offer for the $..... is it me ?

I would see how much those donks are going from the wreckers first.
i doubt they would be any less than 20 grand

I bought a 1HD-FTE, WITH 5spd auto, WITH ALL electrics inc computer with only 25,000km on the clock, for $11500 back in May 2008 From All 4WD spares Milperra.

That's the donk in my Patrol that Stefan is talking about.

See my blog for some details, or get the next issue of 4WD Custom and read about it there.

Fantastic conversion. BTW the V8 was too wide for the chassis in mine also it will not fit the 80s for the same reason.
Cheers Colin.

your a sucker for punishment...best option would be to drive in/drive out...next best option would be the 1hdfte, as it wouldnt need an engineers report, and would be cost effective compared to what you need to outlay for the 1hz IT system. Next best option is a hdft from a late 80 series...that would bolt straight in without electronics, and make enough power to put a smile on your dial every time a 1hzt came alongside...
If you want to be different, what about a 3 litre t/d prado motor?? check the numbers on one of the latest Direct injected ones.....wonder if you could fit two under a 105 bonnet ??

Gday Andrew
TONI is performing very well and I seem to have resolved the tailshaft issue now by playing with the axle rotation.

I have no regrets with my conversion mate.

Hope you and the family are all well and best wishes for the New Year, Cheers, Colin.

We replaced a long motor and a turbo in a V8 ute, the long motor was $11500 without the mark up and the turbo was $3500, without all the other bits like fuel lines, starter motor, injector pump, computer, inter cooler etc: the job was $25000.

My guess is the conversion would cost at the very least, about 35 to 40 grand.

You can buy a Turbo 100 series for that.

Cheers Steve.

I have looked down that path. the 4.5 v8 wont fit between the chasis rails. The 1hdfte is a great idea aside from the stuffing around with the electrics. easiest is a 1hdt or a 1hdft. straight in no fuss. if you are going to keep your current gear box you will need to use your current flywheel at the imput shaft splines are different between torbo and non turbo boxes.

1HZ to 1HD-FT is my dream conversion....BUT....try to find one at a reasonable price, even with the 4,345,739,039,298,239,238 km that will be on the clock. Realistically, if you can find a 1HD-FTE, it would end up being the cheaper option.

I just didn't want the electrical dramas, computers, nor the interference with my HF Radio.... so it looks like I'll be tiptoeing around in the old 1HZzzz for quite some time instead.

Cheers,

Mark

Wow there isplenty of interest with the engine swaps. Does seem the V8 option would be too difficult.

My options now are either the low km 1HD-FTE or an aftermarket turbo kit. The aftermarket turbo kit is probably the least hassel as I have fitted the kit previously and the parts aren't too heavy..! I will call aroun d for a 1HD-FTE fingers crossed for a good one at readonable price.

HAs anyone had experience with the new DENCO glycol/air intercooler? versus air/air.

I spoke to someone else recently who has a 105 series who was keen to do a V8 diesel conversion with the new LC engine, but I don't think he has looked into the difficulties.....yet.

I wish it were easy, as I feel that there will be a few of these engines coming onto the 2nd hand market, given the propensity of the tourists to roll the hire troopys.

The turbo option interested me for a while, until I looked into the intricacies of doing it PROPERLY and maintaining engine longevity. To me this would entail:

1. Dyno pre turbo
2. Engine compression check and general look over
3. Safari split pulse Turbo with Intercooler and boost compensator
4. New exhaust system (2.5 - 3" mandrel bent).
5. Replace gearbox with H151 to cope with the extra power
6. EGT and Boost gauges
7. Upgrade cooling system to cope with additional thermal load
8. Post turbo dyno.

There wouldn't be much change out of $10k for all this and I would be very reluctant to do a half arsed job of turboing a 1HZ due to their construction and the possibility of turning them into a 'grenade'. Likewise the standard gearbox may last a few years, but I WILL eventually die, particularly if doing any towing.

I think the conversion to the 1HD-FT would be a better and perhaps cheaper option if you could find a low k engine as it's a simple bolt up job with minimal electrics. Also you could sell the 1HZ, though it wouldn't fetch many dollars, given the price of a crated motor on offer from some of the dealers at the moment.

I think my second preference would be to get hold of a 1HD-T, rebuild it and fit this. At least it is a motor that was designed for a turbocharger and would end up being a better option than the aftermarket turbo on the 1HZ.

I have read just about every post on multiple forums in relation to all this and many just bolt a turbo on the side of the engine and hope for the best, but I am too poor to do this as a blown engine half way up the CSR would easily cost the money saved on doing a minimalist job in the first place.

Ah well.......Can't spare the cash at the moment anyway..... sigh....

Cheers,

Mark

You mentioned the Denco intercooler, great stuff, mine has that fitted and I am very impressed with it. I cools at low revs unlike an air cooled inter cooler without its own separate fan. Mine is full on even at idle speed and is very efficient at any speed. I have no problem recommending them. Cheers Colin.

Thats mine just in front of the fire wall.

If you want to do a hdft conversion, and cant find a suitable motor, the 1hdfte can be turned back into a hdft by installing a 1hdt pump and hdft injecters. or thesame money, you can get the wiring done and have more power/economy.
