Possible? Yes.
Practical? That's up to you to decide. It'd cost more to get an NA B18B over 200hp than it would to accomplish similar numbers with FI or an NA VTEC B series.

The main consideration is whether this will be a race or street engine.

fast enough to whoop ass? i would suggest making your engine completely back upto factory spec in running condition. then get some sticky tires and learn to perfect driving it. THEN, you can decide what you want to do with the engine.

HmMmM . . . back to stock and learn to drive it ? ? will the suspension system be to high to do cornering ? ? it give me the feeling that the car will over turn or lose traction whenever i turn at high speed I knew it can be done faster everytime but i dare not as i can feel that the car is already badly slanted to one side should we lower it and have a better suspension to start with learning of how to corner ? ? ?

I'm not a fan of superchargers on hondas anyways, so I would say yes.

I love when people say "the LS/VTEC swap" like it's some sort of defined entity. LS/VTEC doesn't mean anything more than a motor assembled from an LS block and some sort of VTEC head. Since it's a custom motor, there are no set specs. It can be anything ranging from a plain ole B18B block with B16A head on it, or something with forged rods and pistons, spiffy cams, etc. Both are an "LS/VTEC."

Honestly you're not going to put 200 to the wheels with an LS motor and maintain any sort of streetability. The highest figure I've seen from an all-motor non VTEC B-series is like 175 to the wheels and that was with a B20B running 12:1 CR and Crower 404 (a.k.a. so lumpy they idle like a Harley) cams. Now that translates to about 200 hp at the crank, so if that's what you're talking about then you'll need to punch the displacement out to 2 liters to get the desired figure.

Now, if you built an LS/VTEC you could hit 200 hp with probably less money invested. Here's a basic outline of what you'd need to hit 200 whp with an LS/VTEC:
  • GOOD intake/header/exhaust--no wussy short ram stuff or stock-sized collector header. AEM CAI, DC JDM 4-1, 2.5" Carsound cat, custom 2.5" exhaust with your choice of muffler
  • B16A head. Add an ITR intake manifold and throttle, skunk2 Stage 2 cams and skunk2 valvesprings/titanium retainers. Adjustable cam gears to tune.
  • B18B block. Forged rods (Eagle or Crower econo-billet are both fine) and B16A pistons. This'll give about 11.3:1 CR.
  • Chipped P28 ECU + A'PEXi V-AFC

Throw it all together, break it in and spend a couple hours on the dyno dialing everything in. Obviously while the motor's apart you'd want to install stuff like new bearings, bolts, water pump, timing belt etc etc etc. It ain't cheap but you'll have a motor good for at least another 100k miles that also makes a ton of power.

i would be willing to bet that a b18b, with those lumpy cams, hondata, lots of headwork, high compression pistons, revving to around 9000rpm could do 200+ crank hp
it wouldnt be worth a **** to drive on the street though
