ls/vtec, why ?

Every sohc or dohc non vtec turbo setup I have seen has not been impressive or does not run very well because not enuff tuning has been invested to make it run properly.

You may make up to 200 whp on stock internals on an ls but if your goal is drag racing, auto cross etc, I personally feel an ls/vtec that does 190 whp will outrun the 200 whp ls/turbo car just because of boost lag, traction issues etc.

Everyone will tell you something different.

Take into mind that an ls/vtec is not cheap at all.
You will spend a lot of money, trust me it all adds up.
