I have done a search on this and I know that it would be cheaper to just buy a supercharged car/engine but I just wanted to know if the NA V6 would be as durable as the supercharged version if it was worked/blown. I know the supercharged V6 would have a compression ratio thats better suited to forced induction but are the internals actually any stronger?
yes mate u would simply spend more money trying get the the job done. But then agian its ur choice if u wanna do that! Good luck anyway!
how about a supercharger from the castlemaine rod shop. http://www.rodshop.com.au/superchargerholdv6.htm i saw in a mag a while ago that had a gemini with vn v6 with 2 of these superchargers bolted on, could be interesting
Well the heads are different for a start and the pistons too. Not too sure about rods, but i think they also have a different counter balance shaft too (correct me if im wrong). Its not worth the trouble of converting your L36 N/A into an L67 if thats what your thinking. Better of buying an L67 or fitting a centrifugal type blower to you current motor although dont know if this will give you what you want. Cheers
Vsteve, i asked about this in a thread before and was told that the only thing the same with supercharged and non supercharged is the block .... everything else is different .....
What model commy do you have? If you've got a VX series 2, its definitely not worth doing. Your ECU cannot be reprogrammed, so you're looking at over $1000 for a new ECU or piggyback alone, plus reinforcing the internals, tuning, and the supercharger itself. As said before, a CRS charger is your best option in terms of bolt on. It runs relatively low psi, 4psi from memory? So it won't put too much load on a relatively weak engine. If you really love your car that much, your best option may be simply buying a front cut L67 and doing a complete conversion. For the amount of money you're looking at spending for such a conversion you could almost do an LS1 conversion. In any case, the ecotech is a relatively weak engine and you're going to need to do some work to the internals if you want some serious gains from a charger.
I have a VT. What do you mean by relatively weak engine? What's weak about it exactly? How much power can it reliably handle? E series and especially AU ford I6 engines can reliably handle 200rwkw and 7PSI of boost on stock internals. Would 200rwkw on stock internals be asking too much from my V6?
200rwkw is alright on an ecotec as long as its a centrifugal blower of some form (ie. supercharger or turbocharger). However a PD blower (such as teh stock M90) are known to damage the ecotec pistons easily when running stock boost. The pistons are shorter hence weaker. As for differences, the pistons, rods, balance shaft, alternator, harmonic balancer and flex plate are all different between the two. I got a price for pistons at $97 each and rods $170 each for the supercharged ones...! Thats from holden at mates rates! Best bet would be to source a complete engine/trans/loom/ecu and drop it all in at once.
You have no idea.The old Buick V6 is quite strong and reliable,and is more than capable of hauling ass.Do some research before making such ill informed accusations.It can handle 8-9psi easily bog stock,push it harder and you will need the internals done.
the buick is different to the ecotec in almost every way. for starters they have a 1" shorter deck height. the buick has stronger rods/pistons standard then the n/a ecotec. the l67 ecotec has stronger rod/pistons, the heads are different because the injectors fit into the head for clearance for the m90 blower etc. forget the castlemain blower only puts out about 4-5psi reliably. you need to look at the raptor supercharger setup. read the thread below http://forums.justcommodores.com.au/showthread.php?t=38026
We are talking about the ecotec, not the buick mate.... Perhaps you should do some research. Not once did I mention the Buick, in fact this is in a VT-VX section of the forums, not VN or VP... Just because its a newer engine doesn't mean its necessarily "stronger" The buick V6 is a far stronger engine than the ecotec as already stated previously by immortality. There are plenty of cars going around with an M90 strapped onto a buick reliably... Good luck finding any ecotecs that can do it reliably without reinforced internals.
Without going into the finer details,the buick V6 is not that dissimilar to the Ecotec.As I said,the Ecotec motor can handle 8-9psi reliably,push it harder and there will be reliability issues.
VX V6 Ecotec(standard daily driver) + Exhaust(2.5") + Vortech S/C(8psi everyday) = 246rwkw for the past 2 years, no worries.......
if anyone can please help us out with vs s/c parts i bought a set of vs s/c pistons from ebay but the dood had swipped the rings pins and gugeons.i can get rings but the gugeons and pins i need and conrods if possible...i need these as soon as possible any help would be appreciated as only person ive found with em so far is barsby spares in Qld and hes asken huuuge prices.if i have to buy the pistons agiain so be it. -cheers ive got the ecotec series 3 5pd getrag from a ute in my vp berlina sedan if youve got any qu's aboutt he conversion i can answer em lol
