in my opinion the best b series motor is the b18c5 motor, its already a beast of a motor with headwork and touch ups from the factory already in place, adding mods to this motor in the right fashion is a step in the right direction for an all motor maniac, now as far as turbocharging a motor that is stock, i would say the b18b for the lower compression and ability to handle a pretty damn good amount of boost with no internal mods and still make good power( i myself have ran 15 psi and the highest i know of is 17psi making 290 hp to the wheels with no problems), now if i was to have my choice of a motor to build completely it would be a b18 vtec motor wheter it be a c or a c5, turbo and vtec plus hondata = lots of power and massive potential to go fast, the higher revving and the ability to make power all the way through the powerband and then some is what i like about vtec and boost, so in a stock motor world,i would choose the ls to turbocharge, but if i could not do forced induction it would definitely be c or c5 because of vtec and compression, b series motor are the best and thats the bottomline..........now price wise is pretty much all the same when it comes to building and turbocharging a motor, pistons and rods around 7-800 bucks, new bearings, gaskets, hondata or some other form of computer, injectors, turbo kits vary largely in price and all the other nick nacs that are involved, i myself have about 4k bucks in motor modifications and thats with a stock motor, you have the turbo kit , complete msd system, injectors, boost controller, apex afc and a few upgraded pieces of the turbo system, its all about what you want (or what you can afford) that is gonna determine how awesome your b series motor is gonna be.........

 

Aight smart ass.......lol "Writing"

 

Oh yeah, just a disclaimer to my above statement. If money were no object I'd say B18C5 all the way. That motor is simply incredible. On a budget though I say B16.

 

couldn't agree more. theres my vote.

 

i'm personally a fan of the b18c5. just like ricky said, stock is just a BEAST of a motor. definitely the best n/a engine in the honda b-series.

 

In stock form I would agree, but not when modded. It takes to minor dodifications a little better then the other Bseries motors, but when full out building the motors I would have to disagree.

 

i was talking stock

 

B18C1!!!!!!!!!!!!!!!!!!!!!!!!!!

 

yeah i agree with opsi on that vtec is good but when u go to true conitunious high revving engine, u dont need anything else to break like pins fro the actuars to lock the cam lobs to the cam shaft for vtec. just go straight high lobe cams..

 

this guy thinks the same way i do. couldn't have said it any better myself.
