gen 3 ls1 350 chev conversion for jk wrangler
 

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)

p.s i am not intrested in any rubish hemi info.

you may have to use a ls2 from a ve for emissions reasons as ls1 are alot older than a jk

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.

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.

G'day Shane here's a link to one being done in Dubai he's using an LSx and seems to have most of it sorted.

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.

Gee mate, with the various Mopar mills the Yanks have available to em, why would they dick around with a chebby???? Not as good as a HEMI.............**)

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

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

not too mention the cost of pcm,s and accessory kits , exhaust headers transmissions etc

Does this mean your not shouting me a beer at jambo????:shock:

and what do you know even mopar sell ls series motors cheaper than there own motors :wall: :wall: :wall: :wall: :wall: :wall:

If your going to do a comparo, how about you do a search:wall: :wall:
Try this sucker on http://www.moparsupercenter.com/6-1l...l037400ca.html A 6.1 crate motor for $5731.00 A hundred dearer than the chev, but includes wiring harness....So before you carry on like a two bob dickhead, check out the facts!!!

rod the hard truth is that it is cheaper to buy a ls2 than it is to buy a hemi go on aev,s website and look at the parts bill required for the conversion then price it all up or infact look at the prices they have on there in us dollars then convert it to aud . considering you can buy an ls2 from eagle auto spares for $4500 aud from dandenong and a pcm for $1000 .
and im sure there would be crate motor ls2s in the usa cheaper than what mopar sell them for .

last time AEV posted on this forum they couldnt even get a 6.1 hemi to perform properly with a 545re auto that is used with the conversion and were getting better results with
the 5.7 hemi .

why you guys think the hemi is the be all and end all of all motors is beyond me


if ya wanna rev it chev it

In OZ to do a Hemi conversion will cost around 30,000K which is ridicolus and hardly any local expertise on Hemi for tunning or parts.
LS is the best option but unfortunately not good for JKs currently bec of the electrics and computer.

Yeah, Hemi might be good but too expensive and oddball for parts in Oz, it's bad enough just owning a Jeep :)

And does a JK need a 5.7 or 7 litre? I doubt it a good 5 litre would be plenty of grunt, going big means you can no longer use standard transmission, axles or CV's. The little 3.8 isn't that bad once it loosens up a bit of course a few more cubes would be nice and the sound of a sweet V8, but not all of us want that many horses to play with. I have no desire to bend my chassis into a pretzel.

Spending an extra $5k rebuilding and moding a LS1/2 with some smick parts maybe even a supercharger to suit a 4WD application instead of freight and import duties on a Hemi would probably produce similar results anyway being easier to get approved/insured and friendlier on the driveline.

anybody do a supercharger for the 3.8?
