Hi all,
i am a 10yrs owner of a 1988 hj61 12ht for which i have done significant upgrades to keep it practical and safe in modern traffic.
Most significant has been adding an intercooler combined with a GTurbo and 3" exhaust system has been the major fun.
If anyone has interest here then i will post some pictures and specs.
The 12ht is the famous direct injection engine, with a lazy laggy CT26 turbo fitted by Toyota runing a very modest 0.6bar boost at wastegate as stock.
Only 136hp from 4.0Litre is a very modest power for such a diesel.
The robust design of the direct injection cylinder heads provides a solid basis for exploiting much higher torque via increased and faster boost.
If these characteristics have meaning to you, and you are lucky to own a 12ht, then you might be interested in my hard work.
thanks for any genuine comments.
