Age long question...b18 or b20...vtec or non-vtec

[civvy2mk]

OK folks, I'm new to the swapping realm and no a bit about hondas but I'm far far far from being an expert. Which is better for a turbo application into a 2000 honda civic ex? B18 or B20 and if B18 vtec or non-vtec. I'm wanting to make somewhere in the 300-325hp range and frankenstein B20's are OUT of the equation lol. Any help is greatly appreciated. Thanks for the time =)

B18C Vtec

Hands down, B18

B18C5 if you got the $3000 to afford it. That or just get the B18C1

LS vtec... LS block can stand more than a GSR block. Do an LS vtec and boost it up to 13lbs on stock internals.

well here's the next part to that...What's the advantage of vtec if I'm boosting. The extra "umph" isn't gonna do me any good AFTER 3k rpm or whatever it takes to kick in if I'm already gettin my butt whooped from the get go. I like the idea of an LS but why add the vtec portion? Wouldn't that be extra money spent unnecessarily?

... cuz Vtec sounds sweet as hell lol. no seriously Vtec gives you more Torque... or HP... or both, i can't remember, at high RPM's. That + turbo = HELLA FUN

That would be like saying why do a turbo + supercharged? if you already have the turbo advantage. Vtec is good for opening valves, those valves will help you to burn what turbo gives you as an extra. LS vtec is the cheapest thing you can do instead of getting a GSR b18c1 which the block won't hold a high ammount of boost. As a personal recomendation I would do LS block and tranny for long gears + b16a2 head. and the extra umph will do more good than bad, Vtec isnt about the sound, its about what it does for you.

i will go with a ls-v but dont forget to get a new gsr/type-r oil pump and a gsr water pump
i am building a motor for my self but im looking for a gsr block. the gsr has oil jets that shoot to the pistons. and i will be putting ls pistons so i can boost 14psi that will be like 350+hp and dont think that this will be cheap i didi my math i will be at $1000+ and i have a
itr head i have the turbo kit ,tranny i still need money to go tune if you dont tune your car then dont builda motor it will never run good and will be a wast of money.

The B18C block is actually a better block than the B18B. It's just more expensive. The B20 is a weaker block because it has been bored out. If you want to be cheap and just throw on a turbo as quick as you can, go for the B18B. If you have the money, you will get more power out of the B18C. Why? Pretty simple, VTEC has more flow. More flow = more power. And when you are racing, you would never dip below the VTEC threshold. So if you can afford the VTEC route, it is the way to go.
