    Vf sv6
    Hey guys I currently have a 2014 sv6 storm with 139000kms I went past my mechanic the other day and he Had a sv6 in the shop on the dyno that had a supercharger just put on with all the little extras and he said after dyno will get around 400kw at the engine I was considering doing this he said it costs about 11k to do this that's with labour and parts.
    I looked a bit more into this and seen that I can get this
    LSA 6.2L Supercharged Crate Engine | LSX Stage 2 | 550 Kw / 740 HP for $15,998 now I require some information on what the other costs would be and if its worth it. Considrting the price for a brand new ss and still have to do alot of work to it for this sort of power.

    Would make more sense to start with a V8 chassis if it's going to be registered. Less hoops you will have to jump through to get it all engineered/certified. Preferably something that already has bigger brakes like a redline.

    Less things that need to be engineered the better. An sv6 would be a headache to get engineered, and even then I'm sure there would be grey areas that could still make your car illegal if you got pulled over by the wrong cop.

    I've engineered big engines into small cars and I couldn't see the value of this project.

    Not that I know many car guys who truly take value into account when it's something they must have.

    To get it engineered you'll need a stronger trans, diff, brakes just for starters plus all the auxiliaries to make those work.

    You may even need to stiffen the chassis.

    It's a big expense to legally fit something like this and if you did succeed to get it on the road it would not be worth a great deal if you tried to sell it.

    As already suggested, at a minimum you should be starting with an SS shell or better still a repairable HSV or give the idea away altogether.

    Add 15-20k on top of your engine. and that's if you're doing it yourself and not paying labour.

    Hmm thanks for some opinions there's a ride off 2014 gts I found that had no damage to engine of interior had been hit from the side near the back and damage the chassis I was gonna see how much he would give that to me for and take alot of parts from that which would support this new engine and its power the price of a vf ss in good condition still go for a fair bit and goin to a gts or r8 is even more. The price I worked out if I built it worked out alot cheaper but the engineering I don't know anything about. Also would be nice to have a what looks like a stock sv6 with 550kw would be a awesome sleeper

    stock sv6 looks like a stock ss tho?
    Buy a high km ss and put the lsa in. Much cheaper and easier.

    Is there a difference in the chassis strength between the ss and the sv6 tho? Because most of.the other parts will have to be changed won't they? E.g suspension clutch gear box etc

    Mite just go with the supercharger intercooler and dyno for 11k for 400kw seems like alot of money and effort for the other option and reason for not selling and buying a ss is I havnt paid this off yet so to sell this I pay off the loan and I have to start from scratch again and standard as comes at 270kw so I'm still winning on power

    Just leave it alone...
    You are planning thousands of dollars worth of mods on a car that you still owe money on...
    By the time you do it all and pay it all off the car will be worth **** all...

    Let him go. We've all been there. You'll do all the work and by the time you've paid it off your bored with it so sell it for a massive loss.

    400kw from a 3.6 sounds optimistic given the LSA outputs the same with a lot more displacement.

    Beat me to it. I don't see how the figures add up either.

    He did say at the engine.. 3.6L at one bar would be equivalent to 7.2L NA..

    just a question on what the internals can handle, dynamic compression can be adjusted with the advantage of variable valve timing.. all sounds doable with some smart tuning..

    alot easier with more displacement though.

    OEM LSA sedan start at $55k (ute $70k). There is a modified maloo with LSA for <$60k and there is probably an SS with LSA for less. Plenty of supercharged L77, LS3 going around which will be cheaper again, much better options than a ridic sv6. If you were a performance shop or stupidly rich Id say go ahead otherwise its a waste of time and money.

    You won’t get a reliable 400kw out of one. Especially since they’re high compression from factory.

    You’d also need to run e85 which means you’ll absolutely chew through the fuel and it’s not the easiest to get either.

    LSA supposedly makes 8 psi which equates to 9.62L NA to make 400kw at the engine.. the v6 would have to be a lot more efficient.
