the ford 1.8 td engine is pretty useless to be honest! Ive tuned many pug 1.9 td engines with great results in the past, the 1.8'scome with the shite lucas fuel pump ( as shown in darrens video^^) which cant really make good power.

You can fit an intercooler easily enough all you need is 2 90 degree pipes for the turbo and inlet manifold ( or find a non turbo inlet manifold) and some boost pipes, a 4x4 cossie intercooler would be fine.

The fueling would have to be adjusted by the max fuel ( black screw in cap on the front) annd the boost compensator (14mm locknut also on the front of the pump) you can also advance the timing of the pump by undoing the 13mm lock nuts and rotating the pump upwards.

Boost shouldnt run more than 20 psi as the turbo will run out of puff and will just make less power.
