    I just had an interesting thought...

    I'm posting this here in OT for discussion, rather than the tech or swaps forums... because it's simply an interesting thought, not really a technical idea (yet... )

    I was looking at the G25A1 found in the Vigor... and it occurred to me... this engine was made around the same time as the F22A. Could it possibly have a port design similar to the F22A?

    I really don't know anything about these engines, as they don't fit into our cars without significant modification... and they've got almost NO aftermarket support...

    But, if my idea is correct (and wikked tells me it's not... he knows more than I do...) then the G25A1 may be the next hidden gem!



    Just a thought. I'd love to learn more.

      mmm 5cyl swap...

      you can have a header made, and that IM actually looks pretty good. the biggest pain would be getting a decent cam made. oh and the TB is on the wrong side, but that isnt that big of an issue. i wonder if it is f22a trans compatible?

        I'm not so much concerned with the swap capability... it'd be a bitch and a half to get it into a CB7...

        Just wondering if the head could possibly be made to flow as well as a modified F22A head. If so... it might just be worth the money to build! I'd take a Vigor if I knew I could build a kickass G25A1 in it

          sometimes a lot of the valvetrain was the same, just that an extra cylinder was added to the head and/or block.

          look at the VW/Audi 4 cylinder and 5 cylinders. they are exactly the same.
          The M10 and M20 BMW (4 and 6 cy) were the same (some what, they had different combustion chambers)

              The only answer I could get from any source was Wikkedv16. He said that the castings are completely different.

              I'd be curious to compare them directly, though... just to see.

                yeh it would be interesting to see just how different they are. i think someone should attempt this swap..

                i will gladly volunteer my car just everyone has to get the stuff LOL

                  Swapping it into a CB7 would be senseless. It would be a difficult fit as a transverse mounted engine, as the F22A is. A longitudinal mount, like it is in the Vigor, would require significant modification (if it would fit at all), and the only transmission option would be the Vigor's transmission. It would make much more sense to just buy a Vigor!

                    True. although i very rarely see vigors in my area. seen one or two in the JY though

                      They're fairly uncommon, especially compared to CB7s. They're often in no better shape than most CB7s as well.

                              Maybe I missed the point your trying to make, but I don't understand.

                              The G25 is 5 cyl and the F22 is 4 cyl so No the exhaust ports aren't the same

                              Or do you mean the physical port design?
