i have a ls1 350 chev and trying to find out who may do the conversion i have emailed burnsville off road in the states and waiting for a reply. i am going to keep this thread going and continue to fill it with info, please feel free to add info for the conversion.
thanks shane norris (tas)
I have been thinking exactly same thing lately since Gen 3 crate motors are getting so damn cheap now.... And there are so many parts and acessories for them....
Dont forget relaibility, local knowedlge, well proven engine. I have enquired a lot the main show stopper is the computer to mate with LS2 or 3 rest all good.
Even the wiring is sorted out.
There is a guy on JK forum did the conversion but mainly for offorad rig, no ABS Air Con etc works but hoping one day someone will come up with the computer

Why not go an aftermarket ecu as well?? Motec will do everything you want an more, and should be easily installed to the ls motors seeing they are so common with many different applications.
Sure, its probably gonna cost you some good coin, but you will have an engine that runs as good (if not better) than OEM. Completely tunable, have multiple maps for air/fuel and ignition for different applications (ie offroad and on road), data recording, and many tuning shops can tune them so its just a matter of finding a good one near you.
You wouldnt even need a motec unit, there are plenty other brands that would work just as well for less money and better than factory results with the added flexibility such units provide you.

The problem is getting the engine CPU to talk to the main CPU under the centre console, unless of course the Motec can control the ABS, ESP, traction control, cruise control, seatbelts, airbags, every other switch & lamp in the vehicle whilst talking to the Instrument cluster CPU.
If you want it to be legal all that stuff has got to work.

It's a Jeep thing, I don't understand............
Bisnut - Are you sure about that? I am not sure what QLD has, but in WA its only exhaust gases that make it illegal/legal.
As for your list, many engine management systems will run cruise control, traction control and ABS. Airbags should (I say that ignorantly) be independant (they should fire without the battery in the car!), seat belts are mechanical, lamps and switchs can easily be rerouted to the traditional hardwired systems, instrument clusters can either be rewired or replaced.
I know it sounds like alot of work, but every engine transplant is!

I'm pretty sure removing the systems concerning ESP, airbag and seatbelt monitoring would be defectable modifications.
If you could duplicate everything in function using approved and tested components for safety systems then I guess they would give the modifications approval.
So I guess the best bet is to get your Engine CPU to talk to the main CPU or have the main CPU ignore it somehow.
I'm no expert in these fangled car CPU things myself, I haven't seen an drawings on exactly how it all works, but I do deal with interfacing machinery CPU's (PLC's) to each other a fair bit and it can be a headache.
Yeah most conversions are a lot of work, and from what I've seen any one with basic skills can use a kit to drop an engine in, to make it a good conversion involves matching the right motor to the application and all the little things like cooling system, throttle linkages and wiring that make the difference between a good conversion and a bad one.

i asked burnsville off road about a conversion kit( like the hemi conversion) but they have nothing, and didnt seem intrested. a four door with a 350 chev would be a great 4x4.
cause the chev is a f...load cheaper to buy than a hemi boat anchor and also chev is a crap load easier to get power upgrades cause of its huge aftermarket support .
Maybe in Aus because of all the dunnydores, but in the greater scheme of things (globally) the Mopar isn't anymore expensive than GM or Formoco.......Check out this boat anchor,http://www.teambrayracing.com/newsit...carsvictor.php and in a Chev to boot. You'd reckon he'd run a chev, in his chev eh???? Obviously the man wants to win!!!Might have to whip down to Haynes hunter and grab myself one of those suckers before someone launches it......

well that is the most stupid comparison i have seen a big block drag car motor to a small block road going engine . jk guys use hemis cause of the computer is easier to match up so the rest of there electric junk works .
all other jeeps usually go for chev engines as it is by far a cheaper and easier conversion to do even the guys on pirate say the chev is a cheaper option that is better for offroad use
cause the chev is a f...load cheaper to buy than a hemi boat anchor and also chev is a crap load easier to get power upgrades cause of its huge aftermarket support .
Was a reply to this stupid comment

it is you spaz ls crate motors are cheaper yes you may find second hand hemis on ebay usa for 1800 us but you will also find the equivelant year chev engine cheapr with a higher hp output
and companies like advance adapters and novak conversions have more options for gm motors than any other
