dont build Ls vtec. a guy at the local track was running 15.3's on his LS/Vtec what was built. all internals done, blueprinted and balanced, i/h/e, msd, hondata, cams springs retainers. the only problem was it was an LS tranny. but shit, thats worse than my LS in a crx, and im running high 14's. If honda didnt make a ls/vtec it probably wasnt ment to be.
If built properly with good parts internally then the LS vtec is fine, it's when people take the cheap route to build it and literally just slap shit together, and don't block off with the proper hardware.
Chances are that kid was a shitty driven or maybe he was running it for the first time ever.
I ran two different b16s in my eg and like my sig says there was a huge difference in both, i used completey different components on the second project and with slicks netted a full second lower et. BUT, the first time I ever took the first project out to the 1320 I started with runnin a 14.7 and eventually hit 14.3 at the end of the night, with the more powerful second motor my very first time to the track I hit a fucking 15.7 with a 3.5 60ft time, and that motor I eventually got to run 13.3 with slicks.
So it just goes to show you that yes it takes time to learn how to properly drive your car and learn how to drive properly.

Um, no. If you don't hook up the VTEC solenoid you are going to get a CEL. And the ECU will go into limp mode. You will have a fuel cut earlier than the LS ECU and more than likely you will see diminished fuel economy. Don't bother running the VTEC ECU until you have the VTEC head, you won't gain anything.
