75 series

if your motor didnt come out with one factory fitted then be very careful as turbo's fitted to non turbo motors generally dont last.the bottom end wont cope with the extra torque produced by the turbo

Had 2 75 series both with aftermarket turbos. Garrett. 200,000.00 klms between them and know dramas at all. Put the extra large radiator in and also when dyno,d made sure they were set up for toueing/towing...not racing. Aftermarket turbos do put some extra pressure on your motor but so does flogging the thing in every gear to get speed up! The larger radiator is, in my opinion, a necessity. $4000.00 for a good turbo fitted is a lot cheaper than buying another car or tranplanting a turbo,d motor in. Nowadays everyone wants a factory turbo drive and this is driving the resale value through the roof and often unrealistic prices. After market turbos are a viable proposition, reliable and good value. The discussion regarding motors lasting or not is as old as the hills. Like anything else, treat it right and it will last. There are thousands of vehicles getting around with aftermarket turbos and many happy owners. Some have had bad experiences(so have many new car owners!), Read the forums and good luck.

lcool.org is a good place to start, there are a few in the process of fitting turbos to 75's now so interesting to follow, i am also getting a 1HZ/HD togeather for a turbo, some very interesting specs to look up but do as many searches as possible on the site, as hard as it is to navigate, as there are some very cranky old dudes on it that dont like answering questions, i am sure some will have there headstones engraved with the "link" lcool.org for any questions about them.....
All aside it is a really good site for cruisers and good people on it...

Never heard of a Super Charger on a 75 Series, some do Turbo them but you are taking the risk of the Big Bang.
Just put a "Non Turbo" sign on the back like I saw posted here recently :-)
The 1 HZ is a great motor if looked after and IF NOT towing will sit at 120 Km/Hr all day.

Ive driven plenty of 1hz 79 utes and many max out at 20kph top speed foot flat for km after km

any hint of a hill will see even that not acieved so im not sure about consistant 120kph running

they just dont have that bit of extra toe of the earlier versions

as for super chargers

kits were around in the early to mid 90s but were withdrawn as they proved to be the best, quickest way to destroy a 1hz

I think the big bang theory depends on the amount of boost you set your turbo at. I have a 99 100 series, and turboed it at 290k. It has now done 384k, and there is not a hint of stress on the motor at all. The boost is very modest - about 5 bar, and iit has turned my old girl into another vehicle altogether.
I no longer have to pick it up and carry it, I can overtake quickly and safely in 5th gear, and tow a 30' van in 4th running around 26-2800 rpm. It will pull the van over most modest hills with very little loss of power in 4th as long as the revs are kept up. I keep it above 2000 rpm and change down as necessary - doesn't happen very often. You don't get neck snapping power, but the torque is fantastic, and it just keeps pulling.
The secret is to get the motor thoroughly checked by a GOOD turbo expert, who should advise whether your motor is suitable for the mod. Mine was done at United Fuel Injection in Perth, and cost $4200 a couple of years ago.

DON'T go for the big boost - you'll get amazing power ......... and a lot of heartache. Gentle boost is all you need.

Yes that is correct going to a max of 7 psi at about 120k's. I usually traveled at 90 to 95 ks giving a boost of about 1 - 2 psi

I had HJ60 which I turboed, the crankshaft had the same number of bearings as later model motors, Ialso fitted aboost guage and it to about 5bar and it never reached full boost until 100km/hr. Av fuel economy of 7 k's/litre best run was 10 ks (once) motor was still running well when traded. The extra power made it a pleasure to drive and gave slightly more than my mates vehicle with extras fitted (about the same economy)

I think you meant 5 psi.
5 bar is around 75 psi

I have a supercharger fitted to my patrol, best thing ever. I have also heard that S/C on Toyota's destroy the harmonic balancer throwing everything out through the radiator, the toyota balancers are just not up to it.
