    I picked up an LSA blower from Eagle Auto Parts, and after six weeks of back and forth, my local shop has lined everything up and will get building in a couple of weeks. This is the end-game (same colour as mine too!).

    How did kit price compare to getting complete crate motor or similar out of smashed car?

    In the same vein as the previous question, how does the upgrade cost compare to selling your redline and buying an R8?

    I’d thing the R8 route would be more expensive buy you’d have all the engineering done from nose to tail (engine, cooling, clutch, gearbox, driveshaft, diff & cooling, brakes)... and the R8 would hold its value better.

    It all comes down to what you can afford when you can afford it . When I bought my car I desperately needed a car that wasn't going to leave me sitting on the side of the highway , so maxxed out what I could afford at the time . After I got my wagon I spent $40k on it . Now on 40/40 hind sight I wish I had that cash up front I woulda bought the $100.000 2017 HSV Tourer in wat eva the grey was and been happy but finances at the time didn't allow . I'm still happy with my heavily modded 400RWKW Wagon but I woulda luved that Tourer

    The bottom line price is higher than I had originally planned, but all-in I should up for $14k, so about the same as a Heartbeat or Harrop setup I guess. Before anyone starts debating the pros and cons of an LSA vs those, I made a conscious decision to try and keep my car as "GM" as I possibly can, and I am not chasing max power, just a nice streetable weekender. This price includes all parts, labour, and tune. This should be an upper limit for anyone planning this because all parts I am getting are new and OEM (pulleys, brackets) or brand name (VCM intake). You can do this cheaper by sourcing parts from ebay and not your local Holden parts desk!!

    I got the blower in GM kit form (never used) from Eagle auto parts for $6500, and I am also adding FI Interchiller blower spacer plates, lid spacer, heat blanket, and doing the solid isolator coupling mod. A used one might have been $2k cheaper, but then how has it been treated, probably needs a reco, injectors are an unknown etc. I am happy to spend $2k for peace of mind.

    In comparison to a Clubsport, after all mods (inc previous tune and exhaust/CAI) I am probably about $10k ahead, but I figure if I had have gone HSV I would have dropped $10k of mods on that too. Plus, as @kleanphil says, I couldn't stretch to a clubby financially when I got the SS.

    Been a long time since pricing them up so was curious how kit stacked up against crate engine price although those parts too.


    Car stuff will usually cost more than originally planned lol

    Who's doing the work?, Make sure they,ve done this before. Mate had one put on his LS3 cost a heap as not a straight forward swap and power output was average. He wished he went Harrop now and saved 5k and extra 50kw.

    Yep, they have experience, but maybe not as much as I would have liked I think! They did a VE in December.. and have a good rep around town.

    Well all done now - got to 369.8rwkw when they ran out of injectors and didn't want to stress the stock valve springs. The LSA cover doesn't fit good as the intercooler hoses hold it up, and with the lid spacer plate and blower spacers, shes a tight fit in there! They used the LS3 throttle body, not the LSA (apparently its good enough / 3mm bigger than the LSA TB) but they didn't rotate it and it is super close to the pulley o_O. Next stop is bigger injectors and double valve springs, cam, pulley :)....

    Hey, am thinking of puting a HSV supercharger on my LS3 to keep it factory/GM looking.

    Do you know all the parts I need to be able to do this?

    sure do. In short you need to recreate the LSA supercharger pully/belt setup which means: LSA harmonic balancer (lower pulley), tensioner, idler, and bracket. New air intake (I have a GM LSA intake, fronted with the VCM GTS air box); S/C cooling setup: heat exchanger(PWR/Magnusson) and coolant pump (Bosch EWP004), hoses and fittings to suit (aeroflow items - look under "supercharger" on their wesbite). I can make the full list tonight and get part numbers - my advice is to ebay all the GM parts or even get them from the US - much cheaper than what i paid!

    thanks, if you could PM the list that would be great. Yes looking to get all genuine GM products as they appear on the HSV version cheaper through ebay or dealer or from states. Do you need the lid spacer plate and blower spacers?

    Yep, this. It is a future precaution that added about $1300 to the build.
