Jesse,
All cars are open to further development in my eyes, just like your ek9 has gone through a lot of development to get to where it is now and that makes it a lot quicker than the FK2 BUT stock on stock the FK2 would be a lot quicker but I feel the Ek9 has the edge on cornering and even though it has those huge Brembos I saw a video of a test between the FK2 and an EP3 and the EP3 out braked it with its 'tiny' 300mm discs and single piston calipers, so definitely room for improvement there with the pad compound.
I think there is a lot to come for FK2, as long as the internals are strong enough (which i'm guessing they will be considering the K20 has such good internals) that we will soon be seeing a lot of 400hp+ ones floating about, and to be fair there no slouch in stock form.
I wonder what diameter the down pipe is on the FK2, exhaust has to be at least 2.5'' i would of thought...
as for modifications i would be interested in seeing the following:
Brake pad upgrade
Suspension upgrade
3'' downpipe (depending on size already)
3'' cat back
3'' de-cat
Custom exhaust manifold
Turbo inlet pipe
and a custom Tune
I think that would make some decent power even on the stock turbo. But I haven't seen many tuners doing anything to these yet, guess its just a waiting game to see who bites the bullet first and tests the strength of the engine.
I was contemplating buying one but I think I would rather wait until they come down in price. £30,000 for a civic is a lot!
