Depends if you mean 400bhp flywheel or at the wheels ? 400 at the fly is hard pushed on stock turbos and ports on a good compression engine. If your looking for 400 at the wheels then a good streetport and a GT35/40 would do it relitively easily with all the right supporting mods.

Good idea to do a search and look at the dyno section. Quite a few good threads coving the subject.

me and Rich (stormbleeder) are in the process of trying to hit 400 ATW with a street port and gt35r, so keep an eye out for our progress!
I dont think it can be done without porting though. :)

It can be done,but you end up running higher boost to achieve it which creates more heat on the inlet temps and also more stress on ancillaries.

so would i be looking at a street port or something more aggressive, as im in shetland i would prefer to port myself so i would need templates(any ideas/help) and i have the means, i teach engineering at a local college so mig,tig,milling,lathes,carbide cutters etc are all available to me.

I have a pair of ported plates (Carl Haywood) sitting in my garage at the moment you could buy from me.  Let me know.

Colin, perhaps you could give one of the vendors a ring to see if fd plates would work on a FC engine.  I would be looking at £240 for the pair.
