Thread: tri -y headers

^^ looking good

Nice. Have any of you guys tried the 4-1 Honda header and modified it? My buddy just got a VE classic so debating on taking on welding up one of these as a practice for myself with my new welder along with helping him out since he has a stock header on it. Planning on replicating the same header the PR boys are running with the PLM collector.

Wish I could run open header on the street!
I wanted to get the PLM collector but decided not too after some members said there no good with a full exhaust. I started with 2.25" pipe for the collector outlet and bumped up the size up the pipe to 3" using a few pieces of pipe using an expander.

what reason was given as to why the plm collector wouldn't work with a full exhaust?

i still have my tri Y still pulls hard.

Can I just weld the sr20ve flange on the tri y headers... why change the order of the tubes?

I think it has something to do with clearing the alt and ac. I have a honda 4:1 but i didnt make it. Pulls hard uptop.

It has to do with firing order and no you can't just cut the Honda flange off and weld on a sr20 one. The header piping needs to be adjusted to fit and the exhaust port spacing is not the same. I have made a few different ve headers and it's a good deal of work to do it right. This is why a good header cost more $.

Well I don't have a/c and I I have a honda half size radiator so space ain't a problem I thought they didn't because of oil pan... ill be the FIRST to try it ... let see how important that change is.. he how the car runs..

Unless u guys did that already?

Your not the first to try it. You can force it but the honda header won't fit without lots of work, I have done this a few times and have also made one from scratch. If your using the honda header to save $ then get the super cheap 4-1 header and cut it up for the parts.
