I would recommend a LS Turbo setup in a civic, that's what I'm doing

 

Both motors are great, but in all reality the longetivity of the motor all depends on the tuning involved. That should be where you put your most focus. I run almost 15psi daily on a bone stock LS. But on the other hand we also made 276/183 with a bone stock b16 @ 7.5 psi. Both motors are great, just find out what you really want out of the car and then make a choice.

what #'s are you putting down with your ls turbo??

 

Boosted sohc is the way to go but if you want to get into the 12's and 11's then a turbo B series is the way to go

 

I'll be retuning very soon and getting some new numbers. My boost controller had a blown out o-ring and kept bleeding off boost. When I thought I was tuning at 12psi it really wasn't, and a pinch in my map vacuum messed with a lot of **** as well. I made 270/240 prolly somewhere around 9-10psi. But I'll be retuned with some definite numbers and some new goodies very soon

 

i'd choose a b18

 

i go with a b18, at least with it you always have the option of adding the vtec head
