Hi all,

Following on from a post I made a bit ago about having my 2000 TD5 90
chipped / remapped.

A few people here pointed me to certain knowledgable chaps with regard
to obtaining more power.

One 'specialist' has said that the intercooler needs to be upgraded to
keep the air cool(er) and the other that the standard TD5 intercoolers
are very good and dont really need to be changed...

So, opening to the floor, whats the opinion? When combining with a
power upgrade (Im looking to take to about 180 - 200bhp if possible
without adjusting boost), should the intercooler be upgraded also?

I am aware that one of the LRO 90's went to JE for a stage 2 tune and
they swapped the intercooler...

Thoughts welcomed.

Jon

Bear in mind that any performance increase comes with a loss of engine
life. To my mind the only way to get significant power increases is to
increase boost and this will affect all sorts of other parameters.

Chipping can only really adjust the fueling and I am not sure that
this is a good thing. I know on one of the local toyota's they include
stuff like limiting torque in first gear to avoid smashing bits and
pieces. Do you think an aftermarket ecu is going to include all that
stuff?

I am of the firm opinion that if your wagon is not powerful enough
then look for a more powerful wagon. I have heard very good things
about the TD6.

Stephen,
Thanks for your input. Funily enough, the chap that I spoke to that
sells plug in power box upgrades said that I would need another
intercooler. The chap that was doing the ECU remap, who incidently
leaves boost, max speed and rev limiters alone, adjusts torque
limiters atc etc said that the existing intercooler was good enough.

I am more inclined to believe the ECU remap guy as he was actually
doing the do and talking the talk as opposed to just plugging in a
box... But the JE are highly resepcted, do the ECU remap and also drop
in an intercooler?!?!?!?!?

The shear power thing isnt really all that important to me, nor is
increasing top speed. Its the bigger torque curve im more interested
in...

TD6 is all well and good, for those with more money than I.
