Alright, it's time to debunk the BS and clear up the fine points...

1) SEARCH.
For the love of GOD, use our search engine.. and skim through the Integra FAQ for the basics. Turbocharging, LS-VTEC conversions, suspension options.. all of these have been covered before.

2) LS-VTEC and its mortal weakness:
The build-up from G2IC.com did not address the bottom end. IMO, that weakness must be addressed for the motor to be considered reliable to any degree.
The specific weak points on an LS-VTEC motor are the rod bolts and to a lesser extent, the rods themselves. An affordable solution for an N/A motor is to have your LS rods shot-peened, then reinstall them with ARP hardware in the stock diameter and thread pitch. That will give you sufficient bottom-end strength to run to 7800 rpm with a little safety margin on top. Being conservative, I would not go beyond 8K, simply because I prioritize durablity.

3) Re: LS-VTEC + Turbocharging.
Considering that a LS-VTEC motor will belch out about 190 hp with plenty of torque, that should be plenty for the $2500 or so it will cost.
(I'm assuming you'll be paying for shop time to dissassemble and reassemble the motor.) In fact, if CA smog wasn't such a bitch, I would be perfectly happy with a naturally aspirated LS-VTEC and an iTR transmssion.

But...if you're serious about turbocharging an LS-VTEC, I would skip the shotpeened LS rods and go directly to a set of aftermarket forged pistons and rods. Shoot for a compression ratio of about 9.8:1 unless you can get 93 octane or higher on a daily basis. The reason for upgrading to aftermarket rods & pistons is two fold..

a) The forged pistons will be more resistant to temporary bouts of detonation. (detonation should still be avoided, obviously)

b) The forged rods will be stronger still than the shotpeened LS rods and will further increase your "safety margin" in high-rpm use. Again, the ARP rod bolts are crucial for reliability.

And yes, so long as B18B1 (or A1, depending on which engine you have) rods are ordered, they will fit the stock crank.

Next... :run:
