they told me that if i were to put a cam and some headers on my d16a6 i would be able to stay up with a b16 and another question does a cam really make a big diffrence in your engine like if i were to get one would i feel the hp gain.

 

It would be highly unlikely. You would need more than that like, valve job, port and polished head, and intake manifold. Then MAYBE you will keep up. Or you can work the block. Either way, that work is expensive, and replacing that tired, high mileage d with a b series would be a much more cost effective route.

 

yea 'they' are full of it.. if you really wanna keep up with a b16, get a b16!

 

Think about it, you are talking about bringing a 1.6 SOHC non-VTEC up to the level of a 1.6 DOHC VTEC by about 52 horsepower (flywheel)... That kind of power in a D-Series motor can really only be found through forced induction like a turbo or nitrous. Even if you did a massive rebuild from the block to the head with aftermarket parts for an all motor setup, you'd have to do some pretty intense compression changes and bullet-proofing to get over 50 hp. A header and a cam upgrade on your D16 will probably net you around 7-10 horses tops.

 

If you do a cam, valvetrain, ported & polished head and intake manifold, and headers, you'll probably keep up. All that will net you around 50hp, and will cost close to the cost of a b. Think about this, swap in the b, then do all that work, which will cost about 2-2.5k more. Now you have like 200hp to the wheels with a total cost of around 4k. Either way, get rid of that d-series.

 

Who even wants a D Series engine?

 

i've kept up and beat numerous b16s with my meansly little d series. granted it's a d15b

 

power to the d15b's
