Just a few Qu’s, has anyone strapped a Supercharger onto a 2H (3.9 mod)?
If so, how easy is it, and how much would you expect to pay for it?
orrrrr, should I just go the turbo like everyone else?

Blower on a 2H
Nice gq swb ute chop with a huffer for the good times

Okay, thanks for that. Do any 40 owners with a 2H + the turbo have any overheating problems?
correctly set up, a turbo'd 2H will have less cooling issues than a NA. by correctly set up, I mean with the fuelling and boost set to a level where the EGT's do not exceed about 550C post-turbo and boost not exceeding about 9psi without intercooling.
the 2H is not what you could call a bulletproof motor and expecting miraculous results from any sort of forced induction will lead to disappointment. the main reason choose turbocharging over supercharging in this application is the minimal increase in crankshaft horsepower required for turboing compared to the significant increase required for supercharging.

Free air locker to the first 20 callers!
someonen on here had a supercharger on thier 2H
something for consideration is the lack of piston skirt cooling, which is used in the factory turbo motor (12HT). Piston skirt cooling was on both the 3B and the factory turbo 13BT making the 3B a good candidate for turbocharging.
you could maybe look into adding piston skirt coling if you plan on rebuilding the motor first, although i doubt the parts to do it will be cheap. (toyota only id say)
some people combat the increased heat by swapping the inlet to the radiator to the other side of the radiator (in a hj60).
although, as dumbsunce said, if the turbo is setup correctly there shouldnt be any overheating problems with the factory cooling setup.
unsure of any turbo 2H provblems in the 40 series utes etc, although they do have a smaller radiator than a hj60, so maybe a bigger radiator may pay off.

I have heard of a few overheating problems with the turbo 2H and the rectification was to have the new water pump fins modified to reduce the speed of the water flowing through the system. I also know that there is a difference between earlier 60s radiators and late 60 radiatiors. The diference is in relation to the car having air conditioing and in relation to the amount of fins on the radiator.
At the end of the day do you want low down power available from a super charger and good for rock crawling or the ease of bolting on a turbo for on road performance. A super charged 2H would be cool but I don;t think that the cost of setting up and the time wasted would justify the extra performance that may or may not be gained from the S/C. Either way the crank will cope with ease although the pistons should be upgraded.
I am running 12psi in my 60 with a 2H and haven;t had any dramas but I have not as yet thrown a car trailer behind it to see what it does.

12psi :o
do you have an intercooler?
Reddo,
I had a Sprintex on my 2H for quite a few years. It was an easy fit, bolt up, no real dramas. The only machining required was the harmonic balancer face so the new pulley would sit nice and true. After a few years I changed the drive pulley on the supercharger to a slightly smaller one to give a couple of extra psi (from 7 to about 9.5). Here's my experience:
Low down torque was awsome, almost too much sometimes causing wheel spin with a slight bump on the accelerator - not good when climbing rocks etc, but the damn thing was almost impossible to stall = good. It didn't have the surge of power that a turbo has, so it didn't feel that quick, but it definately pulled away from other 2H 60's with ease. Hills were not so much of a problem either as you didn't notice them. The fuel economy went up a bit to about 15ltr/100km, but you tend to drive harder when you have more power. In the end I geared it up a bit , and it went better, but started overheating.
Now having a turbo (1HDT), I think a turbo is simpler and has far less maintanence issues.
