A Turbo,intercooled 2h diesel, How many killowatts to the back wheels ?

Bob, kilowatts at the rear wheels varies greatly, depends on the dyno, gear you are in, tyre size etc etc........... The dyno is really just a tuning tool or a means to determine if a modification has had a positive outcome, by comparison, but, the same dyno, tyres etc need to be used for anything meaningful to be obtained.

Is it a toyota turbo or after market. The toyota motor looks the same as the 2h but is called a 12h-t.

I owned a 12h-t 1986 landcruiser for years.

Hi Bob,
I have just gone through all this with my 1HZ cruiser and I can only suggest that you go and get an exhaust gas gauge fitted as this will determine the safe level of boost and then once that is done put it on Dyno and have fuel air mixture set as all questions you ask are really e relevant unless this is done first regards Alan.

If its an after market 2h turbo, I would be very very wary of running anymore then 8lb boost. They where not designed for turbos like the 12ht.
I think you would end up with holed pistons.
Get an egt gauge soi you can monitor your exhaust temps, this is vital for long engine life.

Hey Bob,

Had a 2h turbo automatic, I was getting between 12.5 - 14 L/100km on the highway depending on speed. Averaged about 20L/100km across the Simpson. Under bonnet heat seems to be a drama with them, I removed all of the sealing rubbers under the bonnet and in the wheel arches and this seemed to help keep things under control allowing heat to escape. I had an Aussie Desert Cooler etc etc but it still struggled when working hard up north, ok in winter though.

Mine ran 8-9 psi boost (no intercooler), with intercooler some run around 12psi. An EGT gauge is essential to keep an eye on temps. Higher boost will lower EGT's (for the same fuel) provided that the boost is within the efficiency range of the turbo, inlet and exhaust restrictions. Past a certain point they start generating excessive heat again. Fuel can be matched to the optimum boost, however I wouldn't think much over 12psi is sustainable. They are good around town, on sand dunes or anywhere short bursts of power are needed, but I found that they don't like to work hard past a couple of minutes - such as towing heavy loads.

They are pretty strong, and if it blows then there are plenty of second hand engines to bolt in, or just get a 12h-t which are much better in every respect.

Good luck
Dave

Bob,
no matter what I did with mine I couldn't keep it cool. Tried everything, some of the 2H's seem to turbo and others don't, just like playing Russian Roulette.

Turbo wise, 12 HT engines one the other hand are a very good engine.

Have a good one
