i have a 99 Si. I have heard it is possible and have a buddy that has an EX and put a full GST set up(turbo) and was wondering if any geneation eclipse manifold and all other shit will bolt up to my Si.

If it works, will I be able to keep my A/C?

 

i heard the 2nd gen eclipse manifold will fit the f22a head, but you have to cut the end bolts

 

WHAT!!! Everything will fit besides the manifold, your gonna have the spend the money and get one, or. . . just buy nitrous

 

O yeah it will fit the H23 also....Correct me if im wrong.

 

If it doesn't fit, mill off the flange and have a new flange welded on. Presto-chango. Piece of cake. That's how you can get almost any header or any intake manifold to fit your engine (whichever it is). So long as the ports mostly match up. If they don't, cut about an inch back on the primaries and weld up some new curved primaries.



Or just go down and buy the manifold they make for it.
