JRSCed TypeR hatchback!
I'd hazard a guess at mid 13s. If you don't have the b18c5 hatch yet and are planning on doing something along these lines, I would highly recommend that you turbocharge a b18b or b18c1. You'll get similar times for $3000 less.
GSRT hands down.

I don't understand why so many people come out here (and just people in general) think that the C5 + FI is the greatest thing ever and will be sooooooo fast...
Obviously these people don't do research and realze that you're going to have a much more reliable car with lower compression and be able to boost higher! I just don't get it...[/soapbox]

The Type R has a higher compression ratio, which under boost is more prone to detonation.

That been said, it's a waste of about $1000 to get the C/C5 if you're just going to lower the compression as that, springs, retainers and cams is really all that it has over the C1.
Hope that explains a little more.
You can run 10:1 compression and a decent amount of boost, it's all in the tuning.

as everyone stated, not the best motor to use FI on, not the worst either. just a waste of money. there are much better options out there for the amount of money that a super charged b18c5 would cost. you could build a very nice n/a motor for that price and be running a set of itb's daily. in my opinion that would be glorious. mainly for the sound.
