all B series manifolds interchangable?? like say a ITR or GSR manifold on a B20B? do they fit the same? TIA!

 

b20 is same as LS...if your going straight b20 swap sourcing an LS intake manifold would be nice...

oh because it doesn't hit the hood like the b20 one but its basically the same manifold besides the shape...

LS for CRV
SK2 for GSR
ITR, CTR, SiR, SiR II all the same

 

LS and B20 use a PR4 head and the intake manifolds are interchangeable on both of these engines, although using a B20 manifold is rather rediculous and will hit your hood if used in any civic or integra. Although, both engines use the same exact head and manifold bolt pattern design, which are interchangeable with each other.

B16A/B17A/ITR engines all use a PR3/B16A head and all have the same intake manifold bolt pattern design...so all of those manifolds are intercheangeable with each other.

JDM B18C/SiR+SiR-G & US B18C1/GSR engines both use a P72 head. There's only one OEM manifold that will fit this head, which is the snailshell lookin dual-butterfly intake manifold.


Now, if you're wondering if you can simply bolt up a Type-R manifold on an LS head, NO you can't. The manifold bolt pattern is different as it is for all 3 head types mentioned above. You basically can't mix OEM manifolds, and if you do you'll have to do some extensive modifications.

Another easier route is Skunk2. They're the only company (besides an OEM ITR manifold for PR3 head) that makes a Type-R style intake manifold for all 3 head types; PR4/PR3/P72. You might want to look into that if you're interested in changing your intake manifold to something more power making over stock.

hth.

 

thats exactly what I was looking for thanks
