Has anyone fitted a supercharger to a 1HZ toyota?

Bugger! Not what I wanted to hear, I've been doing some surfing & they are not cheap, but the alternatives are a turbo (same problem) or a engine transplant ie, detroit V8 diesel (much more expensive) or maybe one of the Cummings 4cyl turbo diesels?

well konwn and documented issue. but keeping the boost down and proper fuel pump calabration apparantly can make it work

Careful Smudger,

I used to post identical statements to yours having an 80 series 1HZ that has had a Mike Vine Turbo fitted since brand new for 300,000km.
The motor has never been hot, never used a drop of oil, best thing ever.
A couple of months ago at 310,000km I developed the slightest miss in the engine you ever felt. When the motor warmed up it disappeared. No odd smoke and no oil consumption.
Within a week we were doing a compression test and number 6 was a bit low but all other cylinders were perfect.
Pulled the head off and every piston had huge cracks and were deformed and the entire motor was as good as stuffed. No. 6 had such a big split in the piston nobody knows how the engine was running so well.
I now have a 2nd hand 1HZ with no turbo. I miss the power but I have learned my lesson and will never fit an aftermarket turbo to an engine again.
Factory turbo's only for me from now on.

So what you're saying is that you wouldn't recommend putting a turbo on an old 80 series in case it blows up in about 10-15 years?
Fair enough.

I have done some research on this subject and have found LCOOL forum to be an invaluable source of information.

One of the moderaters on this forum has transplanted at 1HD-FT into a 105 series, intercooled it and it is about the best option as far as I can see. More power, more torque, stronger engine, factory turbo, NO ELECTRONICS, good fuel economy and an easy transplant. The 1HD-FTE is also easy except for the electronic wiring which requires a great deal of technical knowhow. It has been done several times and the result is fantastic, but you still have the computer, which I don't like.

Problems: getting hold of a 1HD-FT is nigh on impossible and when the do come up it is serious $$$$$$$$$$$$$$$ and far more than they are worth for an engine that has more than likely done many km. Apart from that it is a lot of cash to spend on a car worth what the 80 series would fetch on the 2nd hand market at the moment. May be better to hunt down a late 80 series GXL with the 1HD-FT fitted and spend a bit of $$ fixing it up mechanically.

Good luck in your decision. I've decided to travel slower as I simply can't justify the $$ and would rather upgrade the whole car to something with more factory power. Why Toyota didn't make a factory turbo in the 105 series has got me beat. It would have been a real winner.

Cheers,

sorry but you are unlikely to get any more reliability out of diesal gas either.
the 1HZ is a very reliable motor - but it isnt over engineered
- any attempt to get more power from it especially increasing combustion temps as diesal gas does is a lottery

I had one fitted to my 80 series gxl. Worse thing i ever did ! would use about 16lt/100 driving round empty and about 22lt/100 towing a commodore. hate hate hated it. low down torque was good ,sounded good but that was about it. Going up any decent hill, pyro would sit 600-650 c and that was rolling out of it. Had to change a/c compressor to fit intake and replace all seals and sump gaskets and use penrite 60 hpr . I had my fitted in slacks creek qld and i wouldn`t let the bloke check the air in my tyres . they seem to work on nissans but not on tojo`s . I ended up buying a F250 . Problem solved.(mostly)
