Ok

Need to talk to some TDI Gurus. I have aquired a TDI Disco which has no pick up from a standing start. It needs to have a big gutfull of right foot then it gets going. Anywhere I should start or any inherent faults to look for?????. Just might save me some time looking.

Thanks Justin

Hi Justin, its the other one here:p

Ha yes, the old Tdi effect:( AND the fact that you have an Isuzu in the other vehicle.

This is normal in the Tdi , with standard fuelling and pump plunger settings.

Stick a new timing belt on it, increase the plunger lift to 1.6mm and do the 'Thermoguard tweaks' and all will be well:)

There is a company that does upgrade turbo kits in brisbane for approx $2400 all parts included and they say gives 40%more power, You might be able to do it yourself if you know where to start.
also make a mandrel exhaust or talk to TAIPAN performance about the exhausts, less mufflers always helps. as they have a few tricks up their sleeve or in their case, pipes.
The intercooler made bigger will help a lot too as the standard is a bit small and can cause underperformance and overheating,
Have heard a snorkel is a good idea too as the motor draws cooler clean air for the motor.
hope this helps

"has no pick up from a standing start"

Yes, that described my defender when i bought it, and yes, tweaking the injector pump made a huge difference to off-the-line accelleration. It will still disappoint if you are used to Isuzu low down torque. Man i miss that.

Do use an EGT though when tuning. I had my pump done by a reputable LR mechanic and the EGTs climbed easily to above 700 deg after the tweak. Since had them turned down whilst maintaining acceptable performance.
