Can somebody answer these questions ... ?

What is an LS/VTEC? What does the block and the head consist of?

When people say they got a B20 swap, What does that consist of, for the block

and head?

What is compression ratio?

The reason for me posting these stupid questions are ... I am a retard!!!

I looked a little for these questions and then got lazy so i posted them here to

waste your time i guess ... Sorry -

Good resource.

I'm bored, so I'll answer.

And LS/Vtec means that the motor's block is from a non-Vtec vehicle. The head came from a Vtec equipped vehicle. Putting them together requires some modifications. The benefits to this is that you get the low end torque of the non-Vtec block and the efficient top end of the Vtec head. There are slightly more benefits having to do with physics and ICE theory, but you can look those up with Google.

When people say they got a B20 swap, What does that consist of, for the block and head?

A B20 swap, or any "xxx" swap for that matter, means you put that motor into your vehicle. Having a "B20 swap in my Integra" means that I have the Honda CRV's 2.0L B20 motor in my Integra now instead of it's 1.8L stock motor.

What is compression ratio?

I'll try to keep this explanation simple. When the piston moves up and down in the 4 stroke process, there is a space in the combustion chamber. The volume of space when the piston is down all the way at BDC (Bottom Dead Center), versus the volume of space when the piston is all the way up at TDC (Top Dead Center) is compression ratio. That's the basic definition. It gets a LOT more complicated once you get into the theory of it and why it's an important part of how engine's work.</TD></TR></TABLE>

 

^^^ good answer, beer for you!

 

Thanks for the help.

Another couple question's that I haven't been able to answer were ...

How much HP would a Ls/Vtec have, when built?

Also for the B20's, you use the B20 block and the B16 head, right? Or are there

other options for the build?

How much Hp would you have within the B20 build?

No problem at all

Another couple question's that I haven't been able to answer were ...
How much HP would a Ls/Vtec have, when built?

Well, that's somewhat vague. When people say "built", it means that they have fully reinforced the motor with pretty strong internals. These can include, but are not limited to, aftermarket high/low compression forged pistons, forged rods, stronger rod bolts/head studs, custom intake manifold, camshafts, etc. You can even add a turbocharger, supercharger, or nitrous to it.

With these, the power is almost limitless. Tuning is the key element when you're building something that powerful/complicated. There are Hondas making upwards of 700whp. If you're not "building" the motor, and just slapping on a Vtec head onto a non-Vtec block, then you'll probably be making about 30hp more to the wheels about. You can search around for this and see some more exact numbers.

Also for the B20's, you use the B20 block and the B16 head, right? Or are there other options for the build?

There are other options, but it's all dependent on the goals of the car. I'm not too familiar with the setup since I haven't worked with one. Any B-series Vtec head will work. These can be a B18C1 (GSR), B18C5 (Type R), B16A (Si), etc. There are a few more non-USDM variants that can be used as well.

How much Hp would you have within the B20 build?

Again, see my above comment. It's all dependent on what parts you put on, and how well you tune the setup.

OoOoOoO. Okay. Thanx again.

I appreciate all the help.
