    I recieved a bit of info about the motor.
    LS2 with forged pro Pistons, scat rods, double row timing chain, standard Comp. L98 heads with aftermarket valves, springs and pushrods. LS2 HSV cam, 24 x reluctor wheel. 25% under drive pulley. Fast throttle body and standard injectors. HPC coated Pacemaker extractors, LS1 ECU, custom harness.

    The sump will come off to get modified with better baffles and maybe larger capacity. Will have a look at the engine condition.

    I bought a Yella Terra lightweight flywheel, and was told the clutch was pretty new. Pulled the clutch apart, the flywheel has massive heat marks in it. And the clutch material rivets are loose. It worked fine. But it's no good to put back in. So now I need to buy a clutch.
    I figured I can return the flywheel, and buy a twin plate clutch and flywheel package. Does anyone know of something that will work without spending $2500?

    Why twin plate? Just get a Nicks (NPC) single.

    Clutch wasn't going to last when it was built to powerskid in the vl...
    an easy fix is get a mate to drive in front of you at 60 then 80 then 100 and mark in on your speedo with some liquid paper.

    Progress is just researching and buying parts at the moment. Once I have the new clutch, gasket kit and baffled sump kit, the motor can be bolted in. Also going with a new pulley under drive kit. Trying to work out coilovers. And I need to buy the wheels and tyres. Brakes are going to be AP.

    My mechanic is getting me AP Racing brakes. I think they are late model HSV?

    Also, I bought some spare parts.

    Picked up the Improved Racing baffled sump kit today, as well as the Powerbond 25% pulley kit. It already has a 25% pulley, but wanted the Powerbond kit. Just need the sump gasket kit now, and the motor can go back together and be installed.

    AND, I am hiring a complete set of VP Supercar moulds so I can make my own bumpers, wing and stuff. (Might be lighter with me making it all)

    Sorry, forgot. Will ask in the morning. Pretty sure I don't need the 20l and pumps from the VN.

    Oh, NOW VN 's are the hotness. :/

    Looking good mate! I ran a single plate mal Wood ceramic and it was actually pretty good.

    You may also find turning the inlet manifold around and plumbing a filter in the plenum may work and save you the bonnet bulge hassle.
    Turns out, far too much has been written about great men and not nearly enough about morons

    Did you sort a clutch? I use a Mantic twin plate on the vette and it's awesome.

    I wanted to get on the VN bandwagon so I don't miss out on being in the cool crowd. Never thought about turning the manifold. Will look into it.
    I am getting a triple plate clutch. Can't remember the brand, but apparently it's the one that J.B runs in Touring car Masters. Cost was similiar to the Mantic.

    I don't want to go through clutches and brakes this time. So I am spending the money on good stuff straight up. Works out a lot cheaper. I am too poor to buy cheap parts.

    It's a PTT unit. We run the same. They last for ages.

    Pro tip: the flywheel bolt pattern matches most of the ex NASCAR complete units you will find on eBay that are barely worn and cheap...

    Good to know. Not much fun sourcing bits, getting them, trying to fit them and they don't fit. Then take them back...
    Such is race cars. I bought 2nd hand Pirelli slicks of a guy last night, and a set of 2nd hand Koya 18x9.5's this morning. Then did a quick check to see fitment on the rear. Turns out I will need a VL diff. Fuck, should have swapped the one in the VL before selling it. Probably works out better this way as I get a fully rebuilt diff with billet 31 spline axles, new 4.1 diff gears, and new good quality full spool. I figured it was important to have a car that finishes races. So hopefully the diff won't break any time soon.
    The Powerbond harmonic balancer was the wrong one. So took that back, and sourced the right one.
    Still need to source brakes and suspension. I think I need to do the springs to clear the wheels. But the brakes can wait. I may run out of money.

    Not trying to rain on your parade mate, but why wouldn't you build it to comply with IPRA regs - like Adam's VL ? That way it opens up options down the track plus you can always get more dollars for a 3J logged car if / when you decide to move on ?
    LSA R8 Clubsport - for towing...
    N15 APRA Pulsar - for going...
    IPRA VS Commodore - for the "one day when i'm nigga rich" ultimate bogan track weapon...

    Building a race car to meet regs is neither the Lightyear way, nor the PF way...
    "Where can we get hold of a Vincent Black Shadow?" "Whats that?" "A fantastic bike," I said. "The new model is something like two thousand cubic inches, developing two hundred brake-horsepower at four thousand revolutions per minute on a magnesium frame with two styrofoam seats and a total curb weight of exactly two hundred pounds."

    I will build it to suit VicV8's. And modify it to suit IPRA when/if the time comes. But really, IPRA has all these rules. If VicV8's gets really popular, there may not be a need to change. So far the car has had no permanent mods. I will finish the MX5 to race in Sports cars. So between the 2, I am sure I will be kept entertained/poor. And in a couple of years I may sell them and try something else, who knows. But for now, I am happy to give the V8's a go. There is something special about driving a V8. Sure the Jap cars may be faster, but being surrounded by V8's and hearing your own car is bogan heaven.

    If you are trying to get the diff done properly first time around get fully floating hubs. Consider camber/toe etc. talk to someone with high level experience of similar car, or there are quite a few setting up these diffs that know their stuff.

    Ps. It's your car so built it how you want, but got to agree with those suggesting to keep an eye on ipra regs. If not for the competition, certainly for saleability.

    It's about $4500 for a cambered full floating diff. I don't want to spend that much. I haven't done any mods that put it outside of IPRA that I know of. I will do, buy they will be reversible. Like door Windows.

    So far the things that will cause issues for IPRA:

    9.5" wheels
    Slicks (easy/cheap enough)
    VP supecar aero
    6 speed if it is rebodied a VP

    Despite these obvious advantages, pretty sure the front running IPRA cars are still faster.

    Don't forget most front running IPRA cars are 6 figure builds

    All these things are pretty easy to change. Will look at IPRA times. But it's hard to say how much slower I am given I haven't driven it.
