intake manafold

1-how can i deferant between the intake manafold for the d16z6 and the d15b vtec .2- and can i install the b16a manafold in the d15b vtec ? 3- what is the best manafold can i install in the d15b vtec to give me more fuel ?

They would be harder to tell the difference. I don't know of any obvious marks or changes that would show the differenc. No you can't use b series parts on a d series engine or vice versa. I've heard that venom makes good intakes but I know there are several others out there that are nice. If you need more fuel you need to upgrade the fuel injectors, fuel pump and filter, and maybe even the whole fuel rail depending on the application. Thanks to Ridestreet84 for the info on the D16Z6 and D15B headers.

you dont need more fuel on a stock engine. best intake manifold you can get for ur engine that is oem is the one on a d16z6 or d16y8. i would imagine the intake on the d15b is about the same as the one on the d16z6.
