The reason I ask is for a potential D16 in LS and B18 in EG/EK, I haven't seen too many thread about asking which intake, manifold, header, cat, exhaust system type to use.

Any suggestion?

 

all depends on the motor...d/b series parts are not interchangable....

so b18 motor=b18 manifolds and ****....the d stuff will not fit..

your going to need custom exhaust w/ a swap anyway..the cat and exhaust are different lengths

 

So if that is the case there is really no point of putting D in B chasis, as the cost will make it uneconomical.

If that is the case I probably will just go B16 in LS then.

 

you should just keep the ls in the ls a b16 is torqueless and an integra is heavier than a civic

 

put the b16 in an eg and it will be pretty quick....

but yeah..no one goes backwards and puts a D where a B comes stock..
Bseries>Dseries

 

I like integra, but want something that can use less gas, so D15 integra.
