What mods need to be done put a 6l90e into a Vf

[3rspecB]

A HSV-targeted vehicle could simply be an identifier to let assembly workers feel extra pride when screwing their bit into the vehicle in the hope they are better built that the run of the mill unots. Possible part marketing fluff to make HSV owners feel that little bit more special.

But i don't know any details though i've seen pictures of Holden vehicles fitted with dicky transport wheels when shipped to HSV where these transport wheels are then sent back to Holden for reuse... I've also read somewhere that HSV were pulling out Holden installed V8 engines and installing their charged mills which left HSV with a bunch of engines for sale (seems Holden wasn't taking them back). Then on these forums there there were statements that HSV pulled fenders off doner Holdens and installed their own bespoke fenders on i think the GTS-R W1? leaving them with a bunch of VF Series 2 fenders for sale. So HSV-targeted, maybe not so much.

Now my view is that vehicle manufacturers are notoriously cheap and don't like making changes, especially structural to floors just to install a diff, otherwise there is big complience costs involving crash testing. As such i'd guess the big diff is a bolt on proposition, maybe with some bespoke HSV brackets...

It's any ones guess until someone in the know actually drops some facts which can be backed up. Pictures would be great, i like pictures

LS9 was fitted at HSV. LSA and its drivetrain was fitted by holden assembly plant.

Interesting video but it seems a rather inefficient process really.

Can't see why HSV couldn'y pay Holden to install much if not all of the HSV componentry in Adelaide at build time, then do final inspection and programing at a HSV specific section of the Holden plant before the vehicles are shipped off to the HSV dealer network arond Australia. Guess it's a combination of contract issues, phsycological issues and management issues as to why it's done the way it is. Building a vehicle, then rebuilding it some 1000kms away simply seems waistfull and unessesarily costly.

Guess we'll see more of it with the camaro that GM couldn't see the benifit of designing/building in RHD.. Meanwhile Fords laughing on the way to the bank.

Probablty the biggest take on the HSV video is that they use a bolt in parts process as there is nothing structural done to the body. No welding in of any brackets, braces or other body underbody modifications (changing bolt in fenders don't count in my view). Still, nice cars though

Good luck to@br77 in his modding endevours

Taken from a 2013 drive article:

Besides its supercharged LSA 6.2 litre V8, the GTS has different subframe mountings, different transmissions, a rear subframe borrowed the Camaro ZL1 (which is also the source of the engine) and a brake package that’s exclusive to the GTS.

I'm imagining the ZL1 rear subframe is a necessity for the large ZL1 differential. This would explain why I've got no boot in my GTS if I want the luxury of a spare. They just couldn't (be bothered to) engineer it to fit.

I remember there was a lot of 'shoe horning' to get this project across the line.

Guess the term “underbody modification” could mean bolting on the subframe but I meant it as modifying the underside of the body with welded in braces, etc. Ive no doubt HSV did some good work to get it together and across the line but as I understand it’s all bolt on stuff which in itself is not a bad thing.

However, I can’t see that it would be cheap for the OP to source and fit the required subframe, bigger diff and it’s cooling, stronger gearbox, tailshaft, etc, etc. I’d think it may be more cost effective to sell his VF and buy the HSV which has been done correctly and without shortcuts... also easier to insure.

Body reworks to fit LSA rear end was done in Adelaide when building LSA specific bodies. HSV had a lot of input from GM/GMH with the VF GTS. 1st mules for VF GTS LSA where built by Holden Engineering in Port Melbourne. I was lucky enough to drive one of the mules and it was an absolute beast, due to not having esc/traction cals at that particular time.
From memory I don't think the LSA rear diff will fit in a standard commodore rear cradle, so yeah will be an expensive excercise one thinks.

Interesting stuff

Why would you go to the trouble again, like specifically? The torque convertor fits into the 6L80, with proper tune it will not break with even LS9 torque.
I definitely wouldn't do it. OP speak to a trans specialist who offers rebuilds and upgrades to get the tech skinny but is ridiculous vs swapping the best bits into 6L80.
Bolting on an LSA blower is not that much of a torque upgrade to warrant it.

I have done 4l80e conversion in my Ve clubsport. I know it's not exactly what your asking but similar process none the less. Getting the box physically in the car was the easy part, getting the car to run was a whole different story. Lots of trouble with software, fault codes, misfires, non start issues, inhibitor issues. Just turned into a long very expensive process. My recommendation is just don't do it! Sell your car & buy a hsv, much cheaper & less stressful process.

Get opinions from you guys are quite useful, especially when doing the budgeting . If there are lots of unexpected, it will blow my budget for sure

If your referring to the RHD Mustang cash cow then it's not producing like it used to thanks to an ANCAP 2 star rating. Its now a 3 after adding some safety gear (which I read elsewhere they stripped from it for the Aussie market but kept for others) but still had some inherent design issues that needed rectifying.
