engine conversions

I did a v6 engine conversion on a 1994 twin cab hilux 4x4.
Doing it my self took 5 solid weeks at a cost of $7,000
Geting some one to do it for me would have cost approx $12,000.
I sold the vehicle 2 months after the conversion because fuel economy was 320ks to a 70 litre tank around town. and 450ks on highway.
Save your money and brain cells and find another way of powering up (intercooler exhaust etc.)
