Walbro 255.
As for the turbo, I will suggest what I always suggest, the T3/T4. Not the biggest or fanciest turbo, but it is relatively cheap and can get you up around where you want to be. I personally would like a GT3582R, a bit much for what you want but you can't say you won't have headroom. The GT35 is larger but a ball bearing turbo, the T3/T4 is smaller but with regular bearings.
I've seen more and more people running Holsets, diesel truck turbochargers and the like, but you'll have to search for that info on your own. I've only researched the turbos that interest me, there is a lot of turbo types out there to choose from.
As for intercoolers, they follow the same principle as the intake and exhaust tubing. Too small and they will choke the flow, but too large and they reduce velocity. If your goals are for 400hp, search for an intercooler rated for 450-500hp. No point having some gigantic intercooler rated for 900whp with 400whp, especially since that intercooler won't have access to free flowing air across it's entire surface area due to the design of the front end of the car.
