I searched but its kind of hard to search for... i have a b18c1 in my EK and am trying to find the right manifold for it... i bought a whole 99-00 si exhuast kit (from manifold back to muffler) but it comes with the manifold for the b16A2... now will this header work? or will i have clearance problems with the oil pan? or will does the B16 even have the same bolt pattern as the B18s do? me and JDMLyfestyle tryed to put a B16 intake on the B18 head and it would not fit.... regaurdless... what manifold do i need? or will the one i have coming work? or would the b18 not work in the EK chassie... thanks in advance... this hybrid **** is getting old fast haha, but fun and i know it will be worth it!

It will fit.

All B series parts are interchangable with the exception of:

GSR intake manifold is unique and beautiful, like a snowflake. I prefer to think of it as ****** annoying because I want to use a Type R intake manifold and it won't fit.

Also, you can't use NON vtec intake manifold on VTEC heads.

The exhaust manifold will bolt and clear no problem, but you should've bought the exhaust for an EX since that's what you have.

The way swaps work is:

Buy header for your engine, buy intake for your engine, buy intake manifold for your engine, buy exhaust for your car, springs for your car, etc.

 

well i understand all of that... The 99-00 Si's are the exact same as the 96-98 EKs with the exception of the front fenders, headlights, hood and bumpers.. and ofcourse the engine... chassie wise there the exact same and all exhuast and suspention components will bolt right up to the EKs from the EM1s... so i bought the Si exhuast kit because i thought the Bseries manifold will bolt right up to my engine, and the exhuast bends will be perfect for the car.. and the D series engine that comes in it has a smaller exhuast than the B series... So... The manifold i bought will fit... haha thanks again!

The suspension in the back of the EM1 is completely different from the EJ8 given that the SI has rear discs, suspension, different control arms. If you were to swap the rear suspension/braking from an EM1 it'd be a complete replicate though.

All I'm saying is the piping diameter for aftermarket exhaust is usually always the same, so if you bought exhaust for an EX and exhaust for an SI, chances are they'd flow the same, but the exhaust for the EX is more likely to fit an EX even if you're running a B swap. It's possible and highly likely you'll have no problems, but you're less likely to have problems using EX labeled exhaust over SI exhaust. Even a small problem like the axle back rubbing on the control arm could be a small problem you'd have from using SI lable exhaust over EX exhaust.

1992-1995 Civic SI for example.

Same body style as 1992-1995 Civic VX/DX/CX.

Try to use exhaust from one on the other, and you're in for a suprise
