What engine block do you have, m0rk? I demand a response.
Mark, don't suppose you know what gives the JDM Mazda's the additional 10% power over the european market versions do you?
The UK 1.6's sometimes came with the 86bhp engine, which is a total donkey - it's not detuned, it's just crap all round.
I think the Jap engined Eunos' had a slightly raised compression as well.
