Racingbeat Header question.. 84-85 13B vs. 86-88
Ok, so I know the topic of headers is covered here all the time, but my question is a little bit different.
After thinking about what kind of exhaust I want for the new -SE, I came to the conclusion that the stockport system would be the easiest since it comes with the backpressure pickup tube, a feature that the streetport system doesnt offer.
The part that I found odd is that the 2nd gen roadrace header, which is the closest comparable header to the 1st gens streetport header already has the backpressure pickup tube and O2 sensor bung installed.
Now I know that the 2nd gen roadrace header is different than the 1st gen streetport header,
but why would they put the backpressure pickup tube in the 2nd gen model and not the 1st gens?
Is this just because people usually go for a 4 port style engine if they go ported in a 1st gen?
Also, does the stockport system for the 1st gen have an O2 sensor bung welded in as well as the backpressure tube, or would I have to have one put in?
I guess Im just going for the easiest route here, and I want to know what Im up against.
I like the idea of the streetport system, but if the stockport exhaust has everything I need, then Ill probably just go with it.
But...if I have to weld in an O2 bung anyway in the stockport system, I might as well just get the streetport system and weld in the backpressure tube as well.
I have a feeling that Im gonna have to weld in the O2 bung either way, so the most important question is: For the streetport system whats the best place for the O2 sensor bung, and as well the backpressure pickup tube? and will I have any problems with my stock engine since these pieces will only be seeing 1 rotor?
The 2nd gen system makes me think not, but I just figured Id throw this out there for discussions sake!
TIA

I guess the most important question I have is where to put the O2 bung, and backpressure pickup tube in a streetport header.
Front or rear rotor, and how far away from the engine is best for these?

Terrified.
Where the header will meet with the rest of the exhaust, which direction it will be facing. The two exhaust systems are setup differently as neither are mounted the same, and so at the end of the header, one header may be pointed out towards the passenger side more, or one may be going straight out and the other going to the passenger side slightly. It could also work its way in to the center of the car. The end of the header would be facing in a direction to accomodate the rest of the exhaust mounting points according to the car.
And now on to your actual questions - I think the stockport setup will work if you are on stock ports. I don't know how extensive of a mod list you have, but if you have very much at all I will recommend the streetport setup.
I'm not sure in the least about welding on an O2 sensor bung or backpressure tube or any of that ****, but I say go with the streetport setup regardless.
