Everyone seems to have so many problems finding parts for PRV conversions into 505s, and it seems that I've hit the wall also.
I have a 2664cc oddfire block, with 2849cc pistons and liners, with 2849cc evenfire heads, ported and polished, and with a hole drilled to take the oddfire distributor and camshafts, B280 intake manifold with custom extension to clear the distributor and plumbed to a gasresearch carb and airflow meter on top of the manifold (for dual fuel operation), renault 30 flywheel and clutch setup, genuine 505 V6 BA10 5 speed gearbox, and a RHD bellhousing to suit.
Now, the exhaust gasses will flow out of the beautifully flowing exhaust ports and into..... an abomination. The 604 exhaust manifold is, to say the least, PATHETIC.
Does anyone have any experience getting extractors made to suit these engines? Unless someone has a set currently out of a car, that would suit a 505 with power steering that I could use as a template, I'm probably going to have to go to an exhaust place with the PRV in the trailer sitting on a crossmember with a steering rack attached, towed behind a 505 so they should be able to make all the measurements they want!
In that case, does anyone know of any good places in Adelaide to have extractors made? Otherwise are there any places anywhere else in the country that could make them without having the car there, and hopefully get them right?
I've considered using 505 V6 manifolds and downpipes, which are far superior to 604 ones, but for the cost of getting them over here I will be much better off with a proper set of extractors.
And before anyone says anything, the Volvo manifolds are no use, they would direct the exhaust conveniently into the firewall.
