? XT6 ER27 exhaust ports on head ?


Recommended Posts

Just realised seeing an exhaust pipe for XT6 each bank has two ports for three pots

I am guessing one port does two pots, the other just one pot.

 

Are the ports the same size whether they dump one or two pots or is the single a smaller diameter in the head ?

I rate this question about same level of curiosity as to whether the middle slugs pin is removed via the front or rear access plug hole and how long are the c clip plier noses to do such ??

I've seen ez30 with 3 ports per head, i do believe you could get them either way, like you could get a 2.2 with one or 2 ports. the er27 tho are all the same and stupid.... i hate siamised ports. there were some twin port ea82's made and i think if you really wanted to you could make a 3 port er-27 head, but at the same time you'd have more time and money into it then just swapping a eg33 or ez30/36, or a ej20g or ej257... ect.

yes - those are model/year based distinctions - rather than "get them either way" in the sense that they're random.

 

like chux said EZ30 3 port heads are 2005+. before that they're all single port, which i mentioned because the OP seemed interested in H6's with different head/exhaust port counts.

1995 and earlier EJ22 is dual port

1996+ EJ22 is single port.
