you can try stuart wilkins motorsport http://www.swmotorsport.com.au/enginecv.htm for basically all the gear you need, he regrinds a new profile cam for the A series for $120, a closed chamber head is a high compression unit designed for more power and the open chamber head is for low compression fuel economy, closed chamber heads look like a kidney in shape and I think they also have oval ports that are designed to swirl in to the chamber

hmmm it's just that Errol from Datrats told me not to use a ballast resistor so I thought the whole wiring set up would be different now?

Hi just having a bit of difficulty wiring up this new Bosch HEC715 coil to replace the standard ignition coil in my 1200 coupe.
I have a Bluebird series 2 distributor that I bought from Ferrol Errol at Datrats which is easy to connect to the coil with the two wires going to + and - on the coil but am unsure how to wire the coil to the car

I now have my new dizzy from datrats and went out to buy a Bosch GT40 coil got it home then was reccomended by a mate to swap it for a GT40T coil now I read on the box to use it only in a contact points ignition set up so I think I will take it back for the third time and swap it for a HEC715 coil as it is reccomended on the Bosch PDF for the nissan bluebird series 2 which is the same distributor I bought

hey Converted in your old race engine did you run vacuum advance? I remember you said that you run 17degrees advance
heres my new dizzy direct from DATRATS! can't wait to drop it in

hmmm if you say she runs ok when you speed I would think it could be a sticking needle and seat in the carb but it's hard to say without looking at it, maybe replace the fuel filter and run some fresh high octane fuel and a reputable fuel syatem cleaner, perhaps over time the fuel has lost it's octane, happened to my girlfriends bike, after storing it over winter then taking it out in summer it would run fine then start to die when it warmed up I pulled over at the closest BP servo and filled the tank with ultimate 98 fuel started it back up again and 5 minutes down the road the problem was gone!

could you do away with the existing bracket and make your own like mine

ok yep looks like an easy enough installation....does that hose on the left hand side say not for fuel?

I will take one! the gemini parts here in WA are a bit crap to put it nicely! $60 recoed is an awesome price

I would use the standard fuel pump but unfortunateley the hole where the pump goes has been converted into an engine mounting point so thats out of the question. I was thinking of just putting a pump after the fuel filter and pumping it straight into the carb with no return line. Would that work? I don't want to redo the entire fuel system just get the engine running on an electric fuel pump
