D Gas for 2.8 TD

[phil dean]

HI folks, I have a 1998 GU 2.8TD and would like to know if anyone has ideas for giving it a bit of a kick in the tail! Is the DGas conversion a good thing or is there a better way, apart from chucking it out? Phil.

Have you done anything to it so far?
A 3" exhaust, 14Psi boost and an power chip will make a significant difference to a standard motor.

14psi you say... hmmm..

I haven't cranked any boost into mine because according to my boost gauge, under full load it appears to about about 13psi. I know 1 PSI can be a significant difference though.

Oh and to back what Tony said up (not that I need to because he is pretty much God around here Phil) I have done the mods that T0ny listed.

3" exhaust (no mufflers), blocked the EGR off and installed a diesel chip (was like $200 from Italy). It's a fairly big difference in driveability. It's no power house by any means, but it's far easier to drive.

I've picked up a gear around the streets. By that, I mean some hills I know for a fact I need 3rd gear with the standard 2.8. After the couple mods Tony listed, I now do those same hills in 4th gear.

Oh and of course, it's a weapon in the bush in low range, just like any other Patrol with a factory motor.. (ie: not LS1 V8's or twin turbo 4.8's :P )

OK then, MOST 2.8's I believe are running 7-8Psi boost standard so upping the boost to 14 Psi will make a difference, but if you lucky like Timbo and yours is already cranking out 13 Psi then it won't make much difference.
Timbo did mention someting I had forgotten and that was blocking the EGR.

Thanks for the info Tony, I haven't done any mods at all yet, thought I'd get the good guts first! Is the boost adjustable as standard or external bits required? How difficult is chip change?

[YNOT]

Before you do any mods the first thing I would be doing is installing boost and pyro gauges so you can keep an eye on the engine.

Use something like this to adjust boost; http://www.ebay.com.au/itm/Turbosmart-Boost-Controller-Boost-Tee-Brand-New-/150655745446?pt=AU_Car_Parts_Accessories&hash=item2313c83da6

I've never done a chip change so others will be able to help more but I think it's relatively easy if you have some mechanical and electronic knowledge. Some of the more expensive chips may need dyno tuning.
