LSA on LS3 build

[gr33nbastad]

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.

Update - car is in progress now, hopefully all done and tuned by the end of the week... updates shortly!

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 . Next stop is bigger injectors and double valve springs, cam, pulley ....

Nice. Weird seeing the LSA engine cover in an SS

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?

i would with that blower they make alot of heat especially if spun faster and it will help get more even airflow to the back cylinders

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