Civic EG

here is the deal, i bought a b16 head, and then after a couple of months sitting in my house i decided to sell it and stay with the intake manifold and to get some crower shafts and spring and retainers for the b20 head.

My question is, will the b16 intake fit the b20 head?

nope...





definitely not "plug n play". not sure if it can be modified to work or not....

then what type of intake manifold do people put on their b20 stock head when they do the swap to a civic?

the stock one...


one from an LS will work also

ya i used the one from my blown ls on my b20 swap in my old hatch

I put an LS intake on my last car witha B20 in it.

P.S. Juice have you seen a stock B20 intake?

moving to the B series section since this is about B series engines, not hatchback chassis...

sure have... here's member Bouli's boosted B20

that intake doesnt look like the stock B20 intakes I've seen. They have all been way to tall to fit under a civic hood.

isn't that the auto tranny version IM thats too tall???

i believe all the 96 to 97 b20s (b20b) have the tall mani, and tyhe 98to99 (b20z) have the shorter one... but all of the jdm b20s i have gotten have been mixed... some have had either one despite engine code so im not 100% sure on this...

A newer member claimed he put a B16 Intake manifold onto his LS by removing some of the studs off his head. I never saw any pictures of his work, but thats what he claimed.

I have always read that b16/b17/b18c5 heads intakes manifolds wont bolt up to b18c1 heads or to b18a/b/b20b/z heads.
