    Best Cams+Extractors for LFX?

    Apparently the mace cams aren't real great and the xforce extractors seem to be for LLT only? What are the best cams and extractors for a VF SV6 LFX build? And don't bother answering "just get a V8" or "V6 isn't worth modifying" because I have seen 500rwhp builds and it's basically the same...

    Did Holden lie about the power output for the LFX V6?

    I know the title sounds delusional and I don't really believe this claim either but I'm currently in a debate on the YouTube comments section where this guy is telling me that the LFX in the Commodores supposedly has 240kw like the Camaro, but Holden advertised it with 210kw to meet the...

    [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...

    500HP Twin turbo LFX!

    Here's a thread on forum called "G8 Board" in the U.S which shows an LFX making just over 500rwhp: https://www.g8board.com/threads/500hp-twin-turbo-lfx.278449/ The potential on these engines haven't been realised (at least here in Australia) and could give the Barra boys something to pay...

    Hi guys, first time posting, usually just lurking around for info I'm in the process of swapping a VF lfx crate motor into an VE, I'm seeing everywhere that the sump needs swapping but was hoping someone has a manual with a pinout for the ve lfx oil level conector, thinking of possibly modding...

    Ve fuel pressure drop on crank lfx p228c

    My 2013 VE SV6 LFX, has just decided to have a fuel issue one day any not start again. I've replaced both the electronic and high pressure fuel pumps. So on prime I get 60 to 65 psi and the beginning of crank it rolls up to 1800psi, hits 1800 and then dies off to 30 psi and I cannot figure out why

    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...

    Is it bad for fuel pressure to get low on a CAMMED sv6

    Hi guys and girls. I have a cammed sv6, and I was told not to let fuel get below 1/4 in the tank due to low fuel pressure otherwise “[my] engine will blow”. Now my question is, is this true for all driving conditions or just racing conditions?

    Vf sv6 - High idle

    I recently cammed my vf sv6 series 2. However, after driving I soon realised that it was idling far too high at around 1050rpm. I’ve had two tuners set the idle at 700rpm through the ecu, however, in drive it still remains at 1050rpm. Before anyone suggests checking vacuum leaks, as I initially...

    [General] Alloytec Engine Assembly

    Found this great video showing the assembly process of the Alloytec engine. Might help someone. This one is twin turbo, but you get the idea. If only they put a twin turbo 3.6ltr in a Commodore. (Yeah, I know what I'm saying).

    Hi Everyone, Apologies if this had been asked before...I couldn't find this specific info. Can anyone tell me if I can run a LFX Fuel pump in an LLT engine without any modifications? I know that Holden list them as different parts but the LFX pump looks the same so wondering if it will run in...

    Swap a Dead LLT for an LFX.

    Hi Guys this is my first post. I've got an MY10 VE SV6 with an LLT engine which recently kicked the bucket (knackered big end bearing). I want to swap it for the later model LFX engine as they are easier to find, lighter and have a slightly higher power output. I was wondering if anyone...

    LFX 3.6 SIDI - Exhaust, OTR and tune

    Ok, I have a MY12 SV6 SIDI LFX ute that is manual. I've been looking at an OTR for it as I know that mace have been working modifying them for the LFX for some time now. Is it worth putting an OTR on a V6 ? I'd want to put the VCM one on as I know many people with them on their V8's, and they...
