    Yep, slightly improved design over the LLT and slightly higher compression ratio, but the main reason was the LFX is much easier to find and cheaper than the LLT.

    LLT to VF LFX engine swap requirements?

    I’ve posted a how-to in the how-to forum that goes into more detail if anyone wants more info on how to do the swap.

    [VE] How to: LLT to LFX engine swap

    My brother and I recently completed a successful LLT to LFX engine swap for my 2009 SIDI VE SV6 ute and figured it would be beneficial to share the process for anyone else who is thinking of doing the same. The whole swap was completed for just the price of the LFX + cats, with no tuning or...

    LLT to VF LFX engine swap requirements?

    It would probably be beneficial for the community if I made a dedicated forum post outlining how I did the swap. It’s shocking how little info is available out there considering how (relatively) easy it was to do. I always figured it couldn’t be too hard if the shop in QLD were able to do the...

    LLT to VF LFX engine swap requirements?

    The block is identical, although the heads are redesigned to accomodate the integrated exhaust ports, new plastic intake manifold and bigger injectors. I believe the cams are also a little different. But if you swap everything I did they run basically identical to the LLT.

    LLT to VF LFX engine swap requirements?

    I believe in the forum my brother found the guy wasn’t swapping the fuel system like I did. He tuned the LLT ecu to run with the LFX fuel systems, which would probably give you all the benefits of the LFX without the hassle of ECU swapping. But of course tuning can be costly.

    LLT to VF LFX engine swap requirements?

    Ah, the one I had didn’t have a rubber seal. It was just one we had laying around. Certainly not as high quality as that one. Yeah I can see that filter would be better in the long run than a high flow K&N.
  9. LachieKb

    LLT to VF LFX engine swap requirements?

    My experience would suggest otherwise but what makes you say that? The fact the K&N has a good rubber seal around the outside is the most important thing to me.

    LLT to VF LFX engine swap requirements?

    Unfortunately it was a simple matter of the air filter not sealing properly. I just used a cheap paper filter for a service and only found out later it wasn’t sitting properly. I was doing a lot of driving on country dirt roads at the time and it had ingested a lot of dust which scored two...

    LLT to VF LFX engine swap requirements?

    No, didn’t go through the trouble of buying a separate ECU and loom, but that option may still work if you really want all the benefits of the LFX (mainly fuel flex capability).

    LLT to VF LFX engine swap requirements?

    $3000 for the engine with cats, 80,000 ks. Or I could’ve got an LLT with 125,000 for over $4000
  13. LachieKb

    LLT to VF LFX engine swap requirements?

    Well I went ahead with the swap, and it was a success! And surprisingly a lot easier than everyone here was making out. I purchased an LFX out of a 2016 SV6 and the cats off the same car, and that was all I bought. My brother luckily found a forum post from someone in the US who did the same...

    LLT to VF LFX engine swap requirements?

    Almost every LLT engine I can find is at least $4000 with high ks, including out of state, where LFXs are going for about $2500, and that’s for a better engine with lower ks and much closer to me. It will be much better for me to go with the LFX if I can find the info on how to do the swap
  15. LachieKb

    LLT to VF LFX engine swap requirements?

    Well for one thing LLTs are much harder to come by, especially with low ks, and then they’re much more expensive, and less reliable (or else I probably wouldn’t be in this mess). I’ve seen that it’s possible to do LLT to LFX, I just need to know the details.

    LLT to VF LFX engine swap requirements?

    Have you attempted it? Failed?
  17. LachieKb

    LLT to VF LFX engine swap requirements?

    Hmm, perhaps. All I know is the guys at GC Cars Nerang apparently do this exact swap almost every day, and offer to do it for about $4000. That makes me think it can’t be too complicated, but I guess they’ve got the process down pretty well by now. I’m gonna try give them a call tomorrow and see...

    LLT to VF LFX engine swap requirements?

    So I won’t need to replace any electronics/ecu/ecm, just the engine itself, swap my LLT sump onto it, get LFX cats and headers, and use my LLT electronics? Or will I need the VE II ECU and loom as vywgn suggested? The first engine I found fell through but I’ve found a couple others, but both...
  19. LachieKb

    LLT to VF LFX engine swap requirements?

    Ah ok. But I will be able to reuse the ECU and sump from my LLT? Or source those from a VE LFX too?
  20. LachieKb

    LLT to VF LFX engine swap requirements?

    So will my original VE LLT loom, ECU and sump work? Or will I have to source those from a VE II LFX?
  21. LachieKb

    LLT to VF LFX engine swap requirements?

    Well it must be possible somehow because multiple people have done it. I’m just trying to figure out exactly what I’d need to do
  22. LachieKb

    LLT to VF LFX engine swap requirements?

    Right, so I will have to source an LFX ecu and probably wiring loom too in that case. Not sure if the rest of the hardware (sump, intake manifold) will swap from the LLT to the LFX or that LFX crate motor
  23. LachieKb

    LLT to VF LFX engine swap requirements?

    Ah, yeah nah just the LLT. Do you think this crate motor would be a suitable swap for an LLT? Or better off trying to find a Commodore sourced LFX to get all the extra parts with it?
  24. LachieKb

    LLT to VF LFX engine swap requirements?

    Can you clarify your last point? Do you mean nobody would use that particular crate motor for an LLT swap? By “earlier models” I meant the LLT specifically, which is an SIDI engine, so I imagined using this crate motor wouldn’t be much different than swapping for an LFX sourced from a commodore.

    LLT to VF LFX engine swap requirements?

    Says it’s got free shipping Aus wide as well so shouldn’t be a problem

    LLT to VF LFX engine swap requirements?

    I’ll want to be quite sure whether the loom and ecu need to be swapped before pulling the trigger, and I’ve heard from a couple people that they probably do need to be. One option I have is a brand new crate motor from the US for $3,800...

    LLT to VF LFX engine swap requirements?

    I’ll be doing the swap myself, not getting these guys to do it. I just mentioned them to show that it’s possible. I have sent them a message asking for information about the swap process but they haven’t replied, though I might give them a call if I can’t get any more answers on here.

    LLT to VF LFX engine swap requirements?

    The LLT engine in my MY10 VE SV6 ute has recently died on me after running out of oil last year, running with reduced power and an engine light for a while, and now it sounds like it’s dropped a valve and won’t start after driving more than 5 mins. I haven’t had the money and didn’t think it was...

    Timing Chains + Rebuild or LFX Swap?

    My dilemma stems from not having the money for a full rebuild, let alone a brand new crate engine. We have the means to do the swap ourselves so it’ll just cost a weekend really, that’s still worth the effort in my eyes if I can find one with around 100,000km for a decent price. Haven’t ever...
  30. LachieKb

    Timing Chains + Rebuild or LFX Swap?

    Yeah we considered this as well although haven’t checked sensors yet. But that’s just it, could go down the route of replacing chains and rebuilding for it to not even fix the issue. A newer LFX engine is a safer bet, but I’m not sure I’ll find one I can afford any time soon. Is it best to keep...

    Timing Chains + Rebuild or LFX Swap?

    I’ve been having issues with my MY2010 SV6 ute, and I now have a couple options to finally fix it, but both will be pricey and I’m not sure which I’m better off doing. TL/DR at bottom. The first issue is that the 2 centre cylinders are down on compression (both 100psi while the other 4 are...

    SV6 Engine rattle/vibration noise at high rpm

    Fair enough, it’s not much info to go on to make any real guesses. Although I’ll say now that it does seem to be affecting fuel economy and power so I don’t think it’s just a loose bolt. After driving around the city for about 3 hours today my economy was up to 14.1L/100km even driving like a...

    Unless there’s a hidden ash tray in the engine bay I don’t think so

    SV6 Engine rattle/vibration noise at high rpm

    I’ve recently started getting an unusual noise in my MY10 SV6 manual ute. It happens mainly as I reach high revs, about 3k+, and is most obvious when letting off the throttle. Upshifting stops the noise once you release the clutch and the revs drop. If you let off the throttle without shifting...

    2016 VF Ute rear muffler mount changes?

    Oh ok, they fit my MY10 VE ute so that might be a problem. Do you know how much they were changed? The mounts on the pipes themselves are just lengths of 10mm rod welded to the hotdogs so they should be easy enough to bend or re-weld in the right spot so long as the hangers aren’t all that...

    2016 VF Ute rear muffler mount changes?

    So I’ve got a set of rear muffler deletes to fit a VE Ute that I’m trying to sell. I’m pretty sure they bolt straight up to the series 1 VF’s as well but I’ve heard the rear muffler mounts on the series 2 VF utes were changed but I’m not sure. Does anyone know if this is true? Just need to know...

    VE SV6 Ute Exhaust?

    G'day fullas, been looking for some sort of setup to get a bit more volume out of my ute without making it sound like ****. I'm not really interested in a full catback or straight throughs or anything ridiculous, I just want a refined, slightly lower, slightly louder note that doesn't sound...
