Are you talking about a 3L series engine which is a 2.8lt or a 3lt engine which is a 5L series?

Either way it doesn't matter they are both in the same basket.

I own a 3L with a DTS turbo that has done an easy 200,000 Km. I would never go back, if you set it up right they are fantastic. it wont fly but the torque increase is huge. I go up hills now in fourth and fifth that i previously had to rev the tits off it in third.

If you want to know pitfalls to watch for or anything specific you want to know you are welcome to email me. howesy@optusnet.com.au
