Just a general opinion. I'm looking at a Frankenstein hybrid swap. Either a LS/VTEC or a B20/VTEC in my lil '94 Si.
Now, I have heard that LS/VTECs aren't really as reliable as their true VTEC counterparts. I believe that is due to the longer stroke from the stock B18B crank. But I also believe that is the same thing that gives the hybrid a better torque curve than the B18Cs. Basically I would probably be getting a stroker kit if I were to get the LS/VTEC. New crank, pistons, rods, etc., and MAYBE aftermarket cams.
Or I was looking at a B20/VTEC. Which also have a great torque curve. However a lot has to go into making them correctly. See http://www.crvtec.com/. And if they are not done right, then they too can be unreliable.
So, what does everyone think?

 

I think this topic comes up alot, I'd do a search on it and see what other people say.

 

Thanks! And please no comments from anyone about how if you start building up an engine then the reliability will decrease from stock. This is a given. I'm looking for opinions, not criticism.

snap ya axles boyeeeeee!!!!

 

just do a built b20 vtec and you will definatly be happy a friend of mine just got done with his and let me say WoW

Dont deal with the stress of building an engine that gives you minimal performance over built B18C, B16, B18B,etc...... I think most people build a LS/Vtec or B20/Vtec just to say the have one. I would suggest just getting a GSR and building that up. Just my $0.02 tho.

b20 vtec lots of tq more displacment
