Hi, nice to meet everyone.

I have a 98 Holden suburban 6.5 turbo diesel (Aussie Version!). It has the rear mounted turbo the same as in the G- Series vans (so I am led to believe).

The questions I am after is can I run a bigger downpipe from my turbo than stock . On the USA burbs they can run a 3'' downpipe (lol!) to a 4'' exhaust and get great results. Is this also possible with the G-Series as well. I know there is not but room there but if it is can someone put me onto a guy(s0 that make the 3'' downpipe that would be great. as the guys over here are prepared to install one but to make a one off downpipe from scratch will cost me a small fortune and I won't get my bang for my bucks. Or they don't want to touch it.

Any help would be great.

I know almost nothing about diesel. However, maybe if you go to a diesel performance specialist website and give them a shout with that question...

If you have a 6.5 diesel that page is a good resource. Im sure someone there could answer your question.

Thanks Guys, I will, just that I was led to believe the G-Series ran the same motor.

LOL.

The G series did run the 6.5 as an optional engine. I believe most years were without the turbo however.
