Dunno, ask John, and his clients that have been running 15psi on stock sleeves for a couple years.
Ask Chris and Mike from ex Speed Street who have been running upwards of 20psi on stock sleeves for over a year, this motor has been in two different cars, pulling mid/low 11's since I met them early last year.

I ran 15psi on my single cam for months before the unfortunate Gandy 26psi incident.

How about garage advance in Orlando makeing 308whp on a STOCK BLOCK single cam in a CRX? They had that for over a year.

Just trying to say, Honda sleeves are not as weak as some people think.

I've seen gsr's making 280+whp on 8psi, never have I seen 300whp from a B18a/b motor with such little boost. Perhaps there was some nitrous in the mix? Or perhaps the turbo was just stupid large.

It's certainly possible with a large enough turbo, however, not very streetable.

By "well into 200's" I meant 250-275whp on an LS motor.
