Any comments please?
Just need to know will fit fit? Are the mounting points the same and will it give any performance benifits?

 

Only the B18C5 will fit

 

Im in the UK.
Dont think we have them here? Think thats a USDM?
Will B18C4 or B18C6 work??

 

I believe those are the same as the c5 so yes

 

I don't think NON vtec and vtec Intakes are interchangeable.

 

The non vtec integra and the crv intakes are different from the civic si intake and different from the gsr integra. The type r integra intake is a "ported" version of the Civic si intake.

You have 3 bolt patterns, the different patterns are not interchangeable, but I've seen a Type R manifold modified to fit on a GSR if I recall correctly.

If you can't drill and port match to make something fit, you can make an adapter plate. They put the K20 RSX type S manifolds on Honda Prelude 2.2 liter engines sometimes to gain power by using an adapter plate made from 1/2" thick aluminum with holes so it mounts on the Prelude engine and then studs let the manifold bolt to the plate.

 

He's not talking about a non Vtec im he's talking about one off of a b18c4 or b18c6

 

VTi B18C4 will not fit but the Type R B18C6 will.

UK B18C4 = US B18C1

UK B18C6 = US B18C5

 

Mounting points are the same, they are basically the same manifold. The Type R plenum runners are a little shorter than the ones for B16A2.
These are tuned length, engineered for each engine's requirements.

 

Didn't know the c4 was the same as the c1..thanks
