Yours for a mere £2k (a third of the parts cost)...and its small enough to fit a Locost with ease:

Very hardly Locost though.

What engine is it?is says 8v, so im guessing a CA18ET ? like what was in the old Silvia S12?

Yup - CA18ET as per the S12.

mistergrumpy - not as cheap as Pinto thats for sure, but cheap for the amount of power you get - and small enough to fit a Locost. Plus someone else has been through the heartache of getting there..

I totted up what my Zetec turbo cost to date (i included everything) and i'm approaching that already - albeit spaced over a few years!
