1.8ltr turbo and dual exhaust ports
Posted 16 December 2003 - 09:33 AM
I just have a quick question about some of the 1.8ltr old school subbies. I have a diagram of a single exhaust port 1.8ltr turbo XT header that I'm looking at.
I've read that some 1.8ltr N/A engines have dual exhaust ports. Do any of the 1.8ltr turbo engines have dual exhaust ports? Thanks for any help!

Ouch! Well this just put a damper on what I was planning on doing. Oh well! Thanks!

I mean - I know they are on the intake side - with the spider manifold and what not, but I thought they were single port exhaust?

the EJ are all dual port, except the EJ22 from 96? (there was one goofy model, one year only, where they made an EJ22 single port!)
it sucked, so they went back to the standard mpfi...

They were side-by-side, but they were actually separated. I have a picture of a header made for one of these engines somewhere.
That engine was really strange, as the intake and exhaust valves were in the EA82 positions (ei-ie) instead of the normal EA81 positions (ie-ei).
