Hello, I am looking for a good base car to use for the PBMW series. I came across this on ebay and it says in the advert it has a drive chain. Is this a bad or a good thing?

That's a pre-facelift car which has the older 4 cylinder M10 1.8 8v engine which is chain driven. I'm not sure whether or not PBMW regs allow this engine or not, or how it's performance stacks up against the later belt driven M40 1.8v - isn't there a forum dedicated to the PBMW series? If so ask on there whether it's allowed, and how past/current competitors view it's effectiveness compared to the M40 1.8.

Okay thanks. Just been looking at the 2010 regs and you can't have an M10 engine, so that rules that car out. The search continues!

You could by the car and swap the engine for an m40 as body condition should be before engine type

The M10 is a primitive lump of iron when compared with the M40, dating from 1961, and producing about 100 bhp in its injected E30 application, IIRC., against the M40's 115.
It's ultimately a more tunable, stronger engine, though, and the block was used in a 1200bhp F1 engine a few years back.

Built in 2 litre versions for E12 520 and 2002 as well,
