Any anyone done this conversion or know of someone who has. I want to change from the SD33Turbo and want their thoughts if it is actually possible to do it & how difficult. I would much prefer a TD42 but Marks don't do the kit anymore, well they will but costs around $5000. Any thoughts?

I have been looking at conversions for my GQ to main problem is insurance ,most companys wont touch non australian motors any more ie chevs,
I would look at insurance cover first no point spending 12k+ on a chev diesel if no bastard will insure it.
I am looking at a injected 5L dunnydoor motor and running it on gas/petrol, set up the right way will outperform the chev anyway.

Getting insurance was a pain in the backside a few months ago on the Chev conversions but most of the insurers now will cover them without to many problems. This also includes TCIS provided several conditions are met.

You think $5000 is expensive for a TD conversion, chev will be over $10k

As for anyone done it, In GQ's Ive seen a few, but Dave T on Ptrool list has a 400 Chev going in his as we speak. he bought one from Tassie with the goods for $2000! with Rego and all... Maybe talk to him, hes consulted the engineer on whats needed and stuff.

Go with the 5ltr Commode donk, but go with injected, forget carbies!

Another good point was the insurance, TCIS dont do Chevs anymore. ANd they were your best hope.

Red Rover, the V8 6.2 diesel is not a happy puppy at highway revs of around 3000rpm/100km/h which is where you'll find it revving with the 4.375 diffs from the SD33T. So, you would need to look at a ratio change to 4.11 to get highway revs back down to a livable speed. The chev likes about 1800 to 2000 at 100km/h to keep it in it's power band and to return some form od reasonable fuel consumption. It's also going to be a noisey bastard of a thing to live with, and all said and done, not much better a performer than a welll set up turbo six. I think I would invest the $5000 into extracting more horses from the SD33T. Porting, high flow exhaust and intercooling will get it to boogey and retain what is essentially a stock set up.

you would get LOTS of SD33T for $5000!!!!
Blow off any TD42, or V8 Chev Diesel!

Ive heard a few of the Chev Turbo Diesel V8's they sound Horn..... but thats not what its about...

Go with Deserts Idea I think.....

Whats your budget for this project or are you just researching?
