Outer Limits 4x4 Board

Way better than the 4.5 mate... Obviously depending on the tyres and way you drive it. 4.5 about 18 -22per100. LS1 about 15 - 17per100 and for way more power..

The new diesels from chev are just awesome they are called the DURAMAX 6.6 ltr nothing in common with the old 6.5 boat anchorthey have a lot of aluminium and are built strong in the right places

they are very powerful there is a guy in brisbane with one in a nissan patrol that does a 12 second sec 400m run we are talking 1000hp and crazy amounts of torque
best thing is it gets around 12ltr per 100 in his patrol

i am changing jobs soon (shifting islands) moving to vanuatu this will give me more time in aus to build trucks one of the first projects will be a duramax into an 80 should be fun

the downside yes there is one and its $ i am expecting to spend 30 g on the conversion but i will go to the us and buy all the crap myself to save some cash put it in a box and send it over

it wont be as cheap as an ls1 read 2x the cost but would make a better tourer or tow rig

may start a thread once i kick off with the build

cheers

how bout the power gain even without the charger is it impressive?
cheers mick

power gains were good with the NA LS, definatly worth it, havent got to drive it with the charger yet, its in getting tuned atm and im working in WA

so b4 charger signifigant gains!
how bout fuel eco better than the 4.5 or same.
cheers mick
wa dude ur long way from home

bout the same econo as a std 4.5.

i'm pullin 19-20/100 on 37's, and i dont drive it like a fairy

I have done a best of 10.2 ltr/100 with 33" tyres and is yet to be tuned. The Duramax sounds like a very interesting conversion, I will be very keen to see a build thread of this but I will take a lot of convincing to believe it will be "better" for touring than the newer Gen 4 engines. I think you will find the pros and cons of each will probably make it fairly neutral from a performance point of view, and give the LS engine the advantage when looking at cost comparisons and parts availability.
Cheers Zack.

I got mine to 13 on 33's highway. 10.2 is awsome!!!!

new engine or second hand?
cheers mick

mine now owes me less than 7k including engine.. (only had 90thou on it)

i managed to pick a HSV clubby motor, auto box, complete front sub frame with brakes, steering rack, and full exhaust including cats for 2.3k..

i have sold most of the stuff i didnt need it now owes me less than 1k for the motor.

How does the Holden Auto connect to the transfer case? The Engine, loom, tuning etc isnt an issue for me and ill get killalux to do the mounts etc but unsure how to fit up the gearbox side of things.

If anyone is interested in doing the swap in Brisbane i have a hoist, tools etc but doing it all myself is the challenge. If we were to do 2 cars and pool resources it would work out easier

Im using the cruiser manual so i cant help ya there mate, im guessin theres an adaptor... pretty sure Killalux is running auto, so he would be the man to ask

Marks have an adapter to suit the 4L60E and 4L80e, I got the adapter to suit the 4L60 it is well made, but you will have to modd the back of the Transmission sump around the accumulator to give the tailshaft enough clearance.

that sounds ok i get 25-27litres/100 outta my bus but i tow a chippy trailer that probably weighs about 2 ton.
and i have extractors and xorst. oh and im running 35s.
its pretty gutless with the trailer behind it thats why iv been following this thread.
would the motors in question be tourqe enuf 4 my purpose.

The gen 4 engines (6.0 & 6.2ltr) have a lot more torque than the gen 3 engines. A lot dearer, and availability is much less than an LS1, which is easy to find second hand. But despite comments I find the LS1 still has very good low down torque, it is just much stronger higher up in the revs.
Cheers Zack.

Heaps of power mate. Im a chippy aswell with similar set up. I used to tow it with my 4.5 cruiser ute (exhaust, extractors aswell) Youd be shocked at the amount of power and torque the ls1 makes. 3rd gear used to pull like a train and shocked ALOT of people. But even towing when sitting at 100kph it didnt drink much. Its all in the stop, start where it drinks a bit.

Ive settled with a slow turbo diesel 80 series now (weekend toy). But i would highly recommend going the LS1 behind either the manual or auto. Smooth, silent and powerful. Mine was 1 of the first ever done and I was running an after market comp. But killalux knows his stuff and a commodore comp is pretty good.

sumpin to think about later cheers fellas.
since we talking comps now how about after market chips 4 my 4.5 r they any good???
cheers mick

Nope... Not worth it. Even after your spend 8-9K supercharging your 4.5 it still has a dizzy that gets wet and stuff's up. You will be much much happier with the LS1.

Was getting similar till I modded airbox and changed filter to a KN made a uge difference.

What did you change on your airbox? I'm going to be making a new one as the 1hz's old outlet is only about 2.5inch and is a serious choke point in the system. Is yours still a cruiser box or did you use a pod filter?

Yep! thats probably the single biggest thing i love about my LS, I can now drive it underwater! the 4.5 would see a puddle and die!

4L60 adapter to transfer is available from marks. If towing i would consider the 4l80, or atleast upgrade the 4l60 to be a little more reliable.

Another engine to consider is the chev vortec LY6, Basically a LS2, but has higher torque cam and manifold, LS3 heads, variable valve timing, cast iron bottom end. Was used in 08 onwards silverado.

Can be bought out of US for about $5000 AU landed here in around 7 days. If anyone is interested we are buying a couple of them for ourselves in the next week or 2 if anyone else wants one they are cheaper if we buy more.

Power wont be an issue. I know the LS1's well and have a 408 cube stroker with a 2.8L twinscrew supercharger in a GTO Monaro (870hp) and have a spare supercharger for to go in the cruiser too. A good mate in Sydney builds my auto's so thats not an issue. Ive started to get parts together for the mods.

Once the engine is out and the new one ready, how many hours does it usually take to fit?

I cut off the 75mm intake and cut out a square hole about 25% of the airbox then made a transition or square to round intake is now 102mm on the original airbox and used 102 on the lid, took a bit of stuffing around as I wanted to be able to use the wing nut as well to help with sealing. Am currently making a stainless 102mm snorkel so I will have 102mm all the way to Maf. I got from the wreckers an old 80 airbox and did the mods to it so the car was still mobile.

Cranky, I was shit scared to dunk mine at first. Then there was no water crossing too deep. Completely submerged. Never missed a beat EVER!!!!! I have such high regard for them now. Pitty I dont have 1 anymore.
