well, i currently have a 1991 civic si with a built dohc zc engine in it and im thinkin im gonna sell the built engine and go for a more powerful NA setup and have it stock. I am stuck right now between the b16 and the ls. I see advantages with both here, the b16 has more power, but the ls is a little more streetable has more potential and always can be lsvtec'd, and they both would cost about the same. Does anyone know of any certian reliability issues with either of these engines(before the lsvtec thing ofcoarse). I hear there both about as fast in the quarter, anyone disagree? What do yall think would be best? Any other advantages or disadvantages of either? thanks for the help

 

the ls is cheaper and has more torque. or a b20 swap for more torque.

 

how hard is it two swap a b20 into a fourth gen civic? Is it even possible? They seem to be going for really cheap, the b20s.

 

go with a B20....believe me its worth it. A friend of mine has a 91 Hatch and its with a b20. all it has really is B20, B16 trans, and dc header....lets just say it keeps up with a mildly modified integra type R ( remember its fully gutted nothing is inside except the front seats and dash....the integra has full interior )

 

b20z with first gen LSD b16a tranny....real nice setup...

 

It goes in just like a B18A/B. The electronics need to be backdated using 90-91 B18A parts.

If you plan to end up with a 1.8l DOHC VTEC engine, buy a B16A now and swap in a B18C shortblock when you can afford one.

 

true dat...I just need the money to get me a GSR short blocky

 

I'd go with the ls and then look around to find me a R with a blown block....
gotta run fast to get it tho

 

i would think that you'd use old prelude b20 parts from the 2.0Si :eh:

what i really think this kid should do is find a way to retrofit the AWD drivetrain from a CR-V to his civic, of course it would all have to be upgraded due to how small the rear end on that drivetrain is... or meh.. reverse the damn thing and put the front side on the rear somehow, that way you got a RWDriver with a lil power up front to help with corners. .... ahhh... dreams

 

the b20 in the prelude is not the same as the CRV b20, in fact the b20 prelude motor isnt really considered a "b" series motor. There is a kit in the works by a couple companies to do the AWD conversion :rick:
