ls 1,2, or 3 conversion

[karky]

just after some realistic advice as to what fuel economy i could hope to get from a stock ls conversion into a 2016 model patrol. after reliability and just a bit more power when needed for overtaking road trains. the wagon has 33s . also which engine would be the best option. i would really appreciate some advice in this
regards Karky

Welcome to the forum.
Head on over to the introductions thread and say hi.
Lots of good advice to be had.

I had a carby SBC 350 in a 75 troopy and returned 18lt per 100k on the hwy
off road dont ask, would think a LS1 would be a bit more efficient
6lt SC in a Patrol hold me back lol

Ls motors are pretty reliable with lots of aftermarket support. Just have to find one that's been looked after...

I think any fuel figures you get would be as a guide only anyway. Each conversion engine/vehicle combo would give you different results. I did a bit of looking into it a few times (always been on the wish list) and came to expect good and bad. If you nurse it unloaded expect good figures (maybe 13s and 14s), if you flog it or load it up expect to pay for it(into and over 20s). I would expect your 3.0 would generally return you much better figures.

Bottom line is that I wouldn't go into a venture like a ls conversion and expect good fuel figures. I'd go in prepared for the worst but enjoy all the extra powwwer.

If one is concerned with fuel consumption, they have the wrong hobby. Sell up and buy a Prius.

thanks for your opinions and advice. i am in the outback a lot and sometimes 250 to 300 kays between fuel stops. the roads and tracks i travel are 4wd country only so 15s and 16s per hundred would make it a viable conversion.
cheers for the reply Karky

I reckon you would have buckleys chance of getting 15's in "4WD country"... anything under 20 would be a win.

What LPH are you getting out of the 3 litre CRD?
I would guesstimate an LS would use 20% more at the very least.

cheers for the reply KarkyHi mate, I'm currently going down the ls path, what I have learned so far is if you plan to get the vehicle engineered, the motor will need to be the same or newer than the car you're putting it in. This limits you to LSA and maybe ls3, although I'm not sure if the ls3 is still in production? I'm putting an ls1 from a 2004 holden adventra in my 2004 3L. I could put any motor from 2004 on in it but I'm a tight ass and cant afford a better motor(not that the ls1 is a sh!tter anyway lol). You will be up for around 4-6k in Mark's 4x4 conversion parts, plus the cost of the motor, it's much wiser to buy a whole car and pilfer it for bits such as ecu, transmission and even accelerator and throttle cable.

As far as kms out of a tank, as I said, i have bought an holden adventra, I'm going to drive it for 12 months which gives me time to source all the other bits I need, and take the 3L out of the patrol. I can get everything ready and then when the time comes I should be able to swap it quickly. Having driven the car around for 2 weeks, I and getting 16-18 lph driving short trips around town, have got as low as 11 on a semi decent drive but haven't done a full tank of hwy kms yet. I'm getti g between 300-450ks from 60L however the cars fuel tank is only 70L and I don't like letting them get low. Your patrol should hold twice that amount, and if your only doing hwy ks I would take a stab and say you should almost get 1000ks per tank if you drive it moderately. I hope this helps, if you do go.ahead with your plan I look forward to seeing your build thread mate.

Cheers

Rusty

Do you know if this varies state by state? I don't think that's a thing here in SA.

It's a national requirement AFAIK... to do with pollution regs IE you can't put an older dirtier motor in a Vehicle that originally met the anti-pol regs at time of manufacture... unless the engine passes the emmissions testing for the vehicle MY.

Could be wrong but thats the gist of it IIRC.

My understanding of the requirements is that if the engine and vehicle are manufactured after 1987.. as long as you have all the standard emission controls in place you're good to go. It will only become an issue if you cross over the major adr revision dates.. ie.1972-76, 1976-86, 1986 to present day.

So.. you can't put a "leaded" engine in a post '86 car but you could put an ls in pretty well anything built after '86. You just need to have the cats and such installed.

Edit: Actually on those rules you could put an ls in pretty much anything. A motor that complies with current adr's (anything built after '86) could be an option for any vehicle. There's obviously other requirements you need to comply with, but my point is "the engine must be newer than the car" is a bit general and not necessarily correct.

Edit: Edit: Didn't mean to sound like a d*ck about it haha.. just how I understand the rules.

A friend of mine specialises in LS conversions and does a lot of patrols. He just told me that very soon he will have to get emissions tests done on every conversion to be able to get them engineered. $1200 per test whether it passes or fails, if it fails you have to fix the issue and then pay the $1200 to be retested.
He is doing a GU at the moment and is rushing to get it finished so he can get it engineered before this new regulation comes in.

I would believe that. There's a lot of public pressure now for lower emission everything so we're probably about due for tighter regulations. Soon your engine conversions will probably only be practical for club members with a special reg rather than your everyday drivers.

Are you able to reveal who this specialist is? I'm chasing up on competent conversion guys.

Simple practice Gents!
Complete lazy mechanical and electrical nuffy me now. Buy an already legally converted/numbered beast that needs fixing if you’re wishing.
Learn how to modify cooling/toughen what the last big coin bloke got wrong.
Have fun for some years and get aboard the unfortunate Euro emissions crud coming to an island continent soon :-(
