B series Intake Manifold

Do All B Series Manifolds work with eachother?

Example: 1999-2000 Honda Civic Sir Intake Manifold Would Work On A B16A (RSI Motor First Gen)????

Please Let me know

ls/b20's have different flanges then the rest of the b-series.

Generally you wanna keep the IM in the same obd as the car.. but it's definately not impossible

P75/PR4 head (LS, B20) is one type.

PR3 (B16, B18C5) is one type.

P72 (GSR) is one type.

They can fit if you redrill.

Thats not true.
With the LS/b20, you CAN NOT just redrill the holes on the flange to make a b16/itr manifold fit. Its totally different than the b16/itr manifold and the coolant passages are in a different spot. You would have to weld some aluminium to the flange to make the last bolt hole even close to lining up.

You can use a 99-00 SIR intake manifold on ANY generation b16.
