Hiya,

are the 2i heads the same as the fiesta turbo heads? are they a straight swap.

 

i doubt it very much, i'd expect the exhaust valves are sodium filled but not sure?? still doubt there interchangeable though

 

They're identical.

 

learn something new everyday

 

xr2i heads do not have sodium filled valves other than that they are the same

 

i weighed this up a month or so back,

XR2i EFI and Fiesta RST heads, camshaft and valves are all identical,

its only cosy exhaust valves that are sodium filed.

 

S1 heads had the sodium zorst valves, cost too much and wasnt necessary so ford binned it on S2. been told that later RST's had the D shaped ports too, but other than that 2i's have D shaped ports whereas RST's used to have round ones.

 

I'll second that

I DISTINCTLY remember the convo

 

i will 3rd that

Matt

 

cheers lads
