Sell that **** and buy my original Jim B pipe kit. I'll throw in the Starion I/C. You'll be a real OG then!

The up side to this coffee straw piping is that I should be able to route it without any modification to the car, MSM style, and not have anything rattling or rubbing, which is a big deal for me.

The weird thing about the 01 vs my previous 00, is it seems to have much less room in the cold side path. The way ac lines are routed, and the way everything sits, and with my oversized rad, had I run 2.5" piping I would definitely have to trim a few things. And I'm trying to stay away from that. I want this thing to bolt in, just as sturdy as OEM (which is why I'm supporting it with a good amount of brackets) and be beyond a doubt reliable.

And based on my calculations in the fmic/piping thread, this setup SHOULD support the turbo I'll be running, without any choking

I ran full 2" piping on my original set-up. T3 Super 60 @ 12-15psi, I seriously doubt it was causing a restriction at that flow level...

Looks nice. I've got a 2"on the hotside, and 2.5" on the coldside. I honestly have no idea if this is optimal, even after reading your thread on the subject.

That's the kicker for me too, I have read SO MANY THREADS on the topic that I can't even remember what I remember from them, and NOT A SINGLE ONE has direct factual evidence of doing it 1 way vs the other and what exactly happens with different sizing/etc.

Everyone THINKS they know, and everyone has their own "sound" logic towards the topic, but no one has any REAL proof.

LOL

So I'm going to just try it myself and see what I end up with.

Vlad, the civic from the thread I made runs 2" coldside piping and I think 2" for most, if not all, the hotside @500+whp and 20+psi on a 6262

/case closed, haha.

Do the 2" cold side and 2.5" cold side. Datalog the difference. Two pressure sensors, one in the hot side piping, one in the cold side. See if it makes any difference in spool.

You do the footwork, we'll appreciate the findings...

I just tested it. no measureable difference.

Well not true, I did measure the diameters to be .5" different.

Nope, Racing Mazda 2.5" baby, before it was Turbo Tony.

Someone with easy dyno access should just do back to back runs with a piece of 2" pipe thrown in. If there's no difference I'm calling it good enough.

For the head ache of running 2.5", I'm fine with my 2".

Thanks guys. I already have logs and plots from my old setups (though different overall of course, both used 2.5")

I'd gladly test out 2.5" coldside piping back to back with 2" if I had some, but not going through the trouble of fabricating both. Welding supplies and aluminum is not cheap lulz

If for some uncanny reason I end up choking up top and I know its the piping, I'll then sell the setup to someone with a 2560 or something and make another using larger piping.

But like y'all said, it will most likely be fine.

Now to find the QUIETEST vta bov


*edit: also the core just arrived:

You can muffle the bov btw by attaching one of those foam mushroom filters on it. I've heard people stuffing the filter with one of the foam things for washing dishes with even better results.



You can muffle it further by running a small pipe inside the fender and locating the filter in there.

yep, all the extra piping aint worth it...no real disadvantage, just a space/packaging issue
also my inlet is only going to be a few inches long
I'll probably do the little filter thing like triple88 posted
