Sorry to go a bit OT - But what are peoples views of their T3 Flange manifold - you can pickup T3 'super 60's' for cheap and they are meant to spool quickly and be good for around 300bhp/

Anybody have a hunch on whether or not this would fit our cars?
 
I'm gonna say because noone else has - I'd be weary of cast manifolds as they're renowned for cracking.

If you can afford it I'd go for the JBS tubular manifold. Admitedly at ~£500 it's not not the cheapest but people have reported some nice gains with them.

I think you get what you pay for with these, but that's just my two pence
