I fell dumb asking this but, I’m thinking about doing the B16 swap and I want to know what aftermarket parts I should buy i.e. if I want to buy some D.C headers, what car should I buy them for? A 91 integra or a Civic. I was told that If I were to get an AEM cai I should get one for a 91 integra because it is made to fit the frame of my car. Will headers and exhaust be the same way?
different parts you will have to get for different things.
i/h/e you will all get for your CAR not the engine. Unless you want a good 4-1 header w/ larger collector. In that case you don’t really have too many options, and no matter what some fabrication will be needed to make them fit.
Internals you can buy for just about any vtec engine. All vtec cams are interchangible, as are cam gears. Most engine replacement parts you’ll want to order for a 99+ SI or for 94-96 vtec del sols.
no such thing as dumb questions only answers. im pretty sure that since the motor isnt a b18a anymore u should use the b16a aftermarket of course. such as the 99+si b16a lot of companies label for the b16a and others the car itself which i cant find a reason why that would differ. plus the b16a can use ITR top end internals ull hear alot that the b16a head is the same off a b18c5 but the c5 has a slight port and polish which seems reasonably correct. good luck with the motor and im sure their is more but thats all i can think of right now peace
delphilsvtec858: like i said before, some parts must be ordered to fit the engine, others must be ordered to fit the car.
you cannot order a “b16a” intake, or “b16a” header. The b16a came in many different cars (89-91 civic sir, 89-91 integra xsi, 92-93 integra xsi, 92+ civic sir, 94+ del sol, 99+ civic SI). The intakes, headers and exhausts for all those cars are gonna vary because of different chassis and other misc differences. So, for things like i/h/e you order for the car.
but of course, for engine internals you order for the engine.
oh of course i understand that the mapping on the piping and so on will be different but i assume most internals will be for the b16a the part about the intake makes complete sense that it would have to map around certain objects that arent like a 99 si. only thing i dont understand is the header being for a b18a and custom fitting to the b16a head. im not saying its not true im asking why that has to be cause i would like to know when i do my swap i dont wanna get the wrong header.
I think the header you buy for the engine and the i/e you buy for the car. All b-series headers are interchangeable I believe. Correct me if I’m wrong.

actually, this is not the case. your stock b18a exhaust manifold will bolt right up to the b16a head, as will any aftermarket header for your car.
the truth of it is that all b series engines have the same bolt patten and exhaust port location. So, all b series exhaust manifolds (stock or otherwise) will bolt up to all b series heads.
the only fitment problems you will have w/ a header is whether or not it fits around the crossmembers and what not, and whether or not it bolts up to the exhaust properly (this is why if you get a jdm 4-1 header you will need an exhaust shop to modify it in order to make it fit).
I think the header you buy for the engine and the i/e you buy for the car. All b-series headers are interchangeable I believe. Correct me if I’m wrong.
sort of right, but also wrong. all b series exhaust manifolds are interchangible, in the sense that they will all bolt to any b series engine. But they are all not interchangible in the way which they fit into the chassis, and bolt to your exhaust.
unless you want fitment problems or want to do a lot of custom work buy the header for the car NOT for the engine.
I have b16 teg
I have an rs witha b16 when I ordered my aem cai, I ordered the one for a g2 GSR because the b16 and b17 sit in the engine bay the same way. A little hirer than the b18. Makes sense right.
are you sure the b16a and b17a sit higher? If it does its such a small amount that its negligable.
any standard 90-93 intake will fit any b series motor you swap in your car --with the exception of the b18c1 because of its upside down intake manifold. But most people just use a skunk2 IM anyway, so the intake will work fine like that.
What can you use on a B18C? Can a 94-01 GSR pipe be modified to fit, or would you have to do a custom job?
kai: you should just use your stock exhaust manifold, or an aftermarket header for your year of car.
i’m sure a 94+ gsr exhaust manifold could be made to fit, but i don’t see why you’d want to waste the money on it.

Sorry for the confusion, but I ment the intake tube.
kai: i’ve seen people just reuse their stock intake piping. this piping is flexible, and can be routed down to where it needs to be.
i’m not sure if there is an intake out there that will work well with the b18c1’s intake manifold in our chassis.
a good deal of people buy a skunk2 intake manifold for their b18c1, this will allow you to use any 90-93 aftermarket intake, because the skunk2 piece is not upside down like the stock b18c1 is.
