Alright, I am debating between two motors for a swap in my 98 civic. I used to drive a 92 Integra GSR, B17A1 DOHC VTEC blah blah blah, so I know the benefits of the B17. What I'm considering is the B16A2 from the 99-00 Si's. Based on price the B17 is clearly a superior motor, but for the price difference, what are the benefits of using the B16A2?

 

none. they are practically the same motor and put out similar numbers.

 

So the slightly larger displacement of the B17 isn't worth the extra money?(a good bit of money btw)

 

Dammit! People don't read any more do they?

You're tallking about a measly 10hp and 7ft/lbs of torque.

 

Thanks for that, very helpful....

 

Ill save my money and buy the B16.... costs much less than $900 to get 10hp with bolt on parts.

 

no it doesnt

 

B17's cost more because of rarity. B18c is the way to go.

 

i would go b16. b17 bottom end parts are kinda difficult to find since they only made them for 2 years.

 

Check out B18C1's... they're not the cheapest though.
