Dsm Im

[CB7_Saloon]

So ive been curious about installing a DSM intake manifold on the F22A head since the DSM exhaust manifold can be used and if anyone has done it and if so, how it affected the powerband, etc.

Thanks in advance

f22 gasket vs dsm gasket it wont work sorry

You don't use the DSM gasket. You use the F22A gasket and modify the DSM manifold to bolt onto the F22A head.

That is IF the intake manifold can be modified in the same way the exhaust manifold can.
I’m fairly certain an H23A1 manifold would still be a better option, though.

Holy shit, I totally missed the fact that we were talking about the intake manifold and not the exhaust manifold.

um the gasket resemble how the intake runner are on each manifold there obviously to far different to modify them to work your better off make a custom one or porting an h23 intake. if you still do not understand im sorry good luck im out..

The ports would line up. The mounting holes would not. Modification would be necessary to properly mount the manifold.

The issue is in the location of the coolant ports. They do not line up at all, which would be a tough issue to overcome. I’m sure that’s what Jacob was referring to in his rude reply.

Member turbomaxx runs an auto parts store. He not only compared the gaskets, but also measured them. He may post his findings here.

I’ve got tons of pics, bare with me and I’ll try to post them up. Forgot I had to host images elsewhere and link them in here (been years since I got on CB7T but it still feels like home.) I can tell you that it’s likely POSSIBLE but the water passages are a mile off. You’d be better off with an H intake I’m sure.
