B200/B230 "531" big-valve cylinder head
Posted: 31 Jul 2010 12:55 am
Howdy all,
Bit of a long-shot this, but if anyone is looking to build a big-power 8v redblock (300+bhp), this might be just the ticket.
Above 300bhp, you'll need to start looking at the cylinder head. This one has been rebuilt around 2000 miles ago. At the same time, it had larger valves fitted all-round, and was extensively ported. I can confirm the details (valve sizes, extent of the work done at the rebuild, etc) on demand. The plan was to put this on a B230 bottom end with a Holset turbo on the side, and make 400-450bhp...but something came up. It's still not 100% certain...but it is looking quite likely.
Let's start the bidding at £500. It originally cost best part of double that to have it built.
cheers
James
