928 engine builders in the Northeast?
Who are the notable 928 engine builders in the Northeast? In particular, do we have shops in this region that build strokers to the same quality standard as Greg Brown, for example?

No.
There are several that can restore a 928 to working order and then strap-on a supercharger (or send it to He-Who-Cannot-Be-Named-on-Rennlist
for a twin-turbo.) But, if you are looking for someone to build a short block there's no one with a rep in Yankee Land. As far as I know.

That's right, he's not on the East Coast and not even on a coast... It's a thousand mile drive, wake up early and arrive late. Don't forget a case of red bull.

Purist at heart
Ptuomov, LOL, love your humor! Being a purist for original appearance, I can't bring myself to consider forced induction. Too much "plumbing" and visual noice underhood, and concerns (maybe irrational) regarding performance reliability. I understand Herr Kukn represents a more economical solution for goosed torque and power. My dilemma is cost, GB will cost 2X vs forced induction solution. Wish cost did not matter, regrettably it does😢

Porsche 928 S4 is not a unique unicorn: Like with every other four-stroke engine under the sun, turbos are going to make a lot more power than normally aspirated engines for any displacement that is even in the ball park similar. This is beyond dispute. You aren't going to be able to put 700+ hp down at the wheels and maintain drivability characteristics under 2000 rpm that are exactly stock like with any normally aspirated hot rod 928 engine.
Then when you consider cost, the turbos are far superior in hp/$ terms.
Reliability in John's kit is also superb, I drove the car form his shop to Boston for 1000 miles as a shakedown with no problems and the S-007 owner drove his 2400 miles home again with no problems. This is not because it's turbos: For any method of increasing power, there are providers who provide reliable solutions and those that do not. You can make reliable or unreliable turbo systems, like you can make reliable or unreliable big normally aspirated motors.
If however you want to maintain a perfectly stock like appearance, like in those F.A.S.T cars and/or have to fool a smog check **** with your illegal car, then increasing displacement is the way to go. With a big-cubes motor at 6.5L or 7.0L, thoughtfully ported stock intake, high-performance cams, big valve heads, etc. you can make the car look pretty much stock and have 1.6x times the stock power. That's not cost effective hp, but it's pretty cool if nobody can tell what you're packing even with the hood open. I can see the appeal of that.

It's not going to be cheap either way.

Don if you get some time it might be a good idea to make a run to TX to see third coast ,
a boosted car is a lot of fun, and you will get a chance to see what the ole 928 can do on some wide open roads

Yes Stan, plus it would be really helpful to see how other sharks have been tuned, regrettably we don't have a large 928 community in the New York metropolitan area...I am the only one in Manhattan on this forum (maybe the only one in Manhattan period).
