LS/VTEC definition?
The definition of LS/VTEC can be looked at in a couple ways. I want to see what the Honda community thinks?
Scenario #1: B18A/B LS block, 89mm LS crank, VTEC pistons (cast or forged), VTEC water pump, VTEC oil pump, DOHC VTEC head of your choosing, VTEC oil squirters for cast pistons, and all the other hardware WITH LS/VTEC oil lines etc.
Scenario #2: B18C1/5 GSR/Type R block, 89mm LS crank, VTEC pistons (cast or forged), VTEC water pump, VTEC oil pump, DOHC VTEC head of your choosing, VTEC oil squirters for cast pistons, and all the other hardware WITH NO LS/VTEC oil lines etc.
Can both be considered LS/VTEC?
I've been told that scenario #2 CANNOT be considered LS/VTEC and is just a stroked GSR motor, and that a true LS/VTEC has to have B18A/B stamped on the block.
I personally have scenario #2. I prefer a perfect fit between the block and head and no oil line hassles. It also looks like a normal GSR motor, but has the different internals. The other huge benefit is that you will visually pass a California smog test. If a legit smog ref or tester sees a VTEC head on a B18A/B block, it is not legal, and you won't pass.
What do you all think?
