best "real" holden six for boost - Page 2 - Aussie V8 | Holden - Ford

202 to 205 cubes. Dont need any more. Just give it 10lbs and it'll be fine. You can put the toyota supra blower on it for not much cost. And they have a switch to turn it off if you wish.

what sort of power output with that setup? What setup for the bottom end?

Green you might get away with starfire/ blue motor rods witha set of 11/32 ARP bolts. As for the cam go around 112lobe seperation angle 220deg at 50or more. A reasonable head like a stg 3 with a port job. 1.6ratio rockers would be nice. 8.5:1 comp would give you a FCR of 14.28 with 10lbs in the hole.

Thanks for that mate, That does seem like a feasible and cost effective upgrade, I think hadfield does blower kits for the straight six. will it give me 300 ponies and does it leave room for more when I inevitably get greedy?

hi greenhj yeh mate that was pauls car at heathcote PROFC its off it head, that old nasty nitrous set up motor i brought off him, its in my lc torana, iv still got it on nitrous and i ran 13.1 @ 108mph at heathcote last year in it, on 165r13 stockies have a look at my profile and ul see it. As for your last post if you go 30 or 40 thou over in a 202 it will be around a 208 cube, u dont need masive rpm to achieve the 350hp you wont. safely run around 15-20 pounds with a good set up, get the right comp as low as you can and it should be reliable as. you dont need a huge cam or it will be a pig to drive.
