Some valid points Slaz

I would not call ~140kw high for a B series, I wouldn't even call 150kw high. It's a good figure to achieve, i'm not saying it's easy, but if I wanted to aim for a big B series, I'd be hunting the 200kw figure, as for that matter, I will be chasing that soon on standard sleeves. If it gives, it gives.

I have the feeling this guy wants to build a B series and be serious about it, in this case it would require some big research and heavy blueprinting work.

To the OP,

There is alot more to buying x pistons and using them in the block, there is certain clearances to be checked as a start and even then, I would modify the pistons to suit my needs. I find that there is a massive misconception about building motors and making power, alot of people think the most expensive parts and the best branded items will make power. The assembly plays a massive part in making power and reliability. Aside the technical aspect of manifold design and head design - probably the most complex and grey area to be talked about.

I see this thread turning into a technical analysis of the B series motor?


Benson: Albeit there is some good combo's out there making good power, not everyone is the type to follow others and the OP sounds like he is chasing alot of power/torque from the B series project - seems to me something a little more radical that no-one has really chased yet.

OP, can you please state your goal for this build?
