Why build a LS VTEC Honda engine?

There’s many reasons behind the question of why is LS VTEC such a good engine, and we take a look at a few of the talking points below.

It’s Cheap – For a fraction of the price, you can build yourself an engine that produces more horsepower and torque than the B18C5 Type R engine. Allowing to put your own together may take more time and effort, but it’s ultimately more rewarding because you know what is in your engine.

More Displacement – If you are looking to build a CRVTEC, the 2.0 liter engine from the Honda CR-V makes for a potent beginning to your LS VTEC adventure. Make sure to check our guide on how to build a reliable LS VTEC here.

Cons of a LS VTEC Honda engine?

There’s also quite a few cons to this setup, and here’s a few of them.

Elbow Grease – It’s petty and a minor detail, but let’s face it the LS VTEC is not for everyone. Either you aren’t mechanically inclined or don’t have the patience or means to properly build a LS VTEC, there’s quite a few people who fall under either category.

Modifications required – Looking to get the most out of your LS VTEC or CRVTEC setup? Take the proper steps and reinforce your engine so that it doesn’t fail on you. Most LS VTEC engines give out when the rod bolt is stretched past it’s tensile point, which can result in disasterous damage.
