Is there much you can do to the 3.1 diesels for extra power?  Possible to mess about with the boost?

Cheers in advance

A lot in short

More fuel, more air, more boost, more intercooling... but if your going to play with the boost, get a propper boost gauge and an ETG

Yep, front mount intercooler, pump optimisation then maybe boost increased.  A free flow filter and bigger exhaust may also help a little.  Also replace the viscous fan with an electric setup and remove any power sapping accesories like roofracks, bullbars etc.

I have just finished playing with mine, so far I have done the following....

Blanked off EGR valves
Adusted fueling screw
Fitted K&N induction kit (got hold of a rover 220 kit and it went straight on)

and with these 3 cheap mods ( about £55 for the K&N) it really has transformed the car to a much more sports (if I dare use that word) like drive.

Will be towing next month with it so looking foward to see if the torque has improved because it really is a diffrent car !

now should I play with the turbo boost........ mmmmm

Hi Guys,

I've also got a 3.1td. While i realise that these aven't rocket ships they do get along....

In reply to Little Troopers post:
Where is the fueling screw? Roughly how much to adjust for a sensible increase in power?

This is the first Oil- Burner i've had. I've just got rid of my modified petrol 2-litre turbo Saab with 225bhp.

Cheers

look on the back of the injection pump ,at 1oclock there is a metal security cover over the mixture screw prize it off ,it can be awkward ,underneath is a screw and lock nut ,undo the locknut and turn the screw 1/3 turn clockwise ,tighen locknut ,testdrive ,it might nead abit of fine ajustment either way but 1/3 is usually about right,not too much black smoke,expect 10/15 more bhp.

check out this link and half way down you will see a dodge ram link with a picture of your pump and the location of the screw....

I gave mine half a turn in and then had to take the idle back down as it went up to about 1100rpm, I could have gone a bit more with the screw but then it started to smoke under load.
Had to put the space in the link as it wouldnt let me post it.

would it be worth changing the waste gate to an adjustible one from a lr 200 or 300tdi
