My custom B-Series header design!

BALLS!

The motor that's in the car made 675hp to the wheels with a small GT30, and a log turbo manifold. With the new setup, it should make 800-900 hopefully.

We ran 11.8 @ 116 with a bone stock B18 out of the junkyard on a 150 shot, I think it's possible

Here's the infamous Civic, it's got some $$$ into it lol

Given the size of the car and the length of the header's pipes between the bends and the collector, I'd be more worried about tripping over the turbo when walking from the front of the car to the driver's door. The engine in a civic is on the "wrong side".

Is that a funnel?

NOT a compliment.

Should have piped in the conversation then. I believe the complaint was corrosion. I'll be taking care of that today. Believe it or not, I WOULD have appreciated your input.

What conversation was this?

Oh ok lol

No no, Sperglordo meant it as a compliment.

Pacesetter's actually aren't very good, if you use good steel (321 would be nice) and clean welds yours will be better

In reply to Osterkraut:

Correct.

I always understood that a long pipe was good for low end and a short pipe for high end.

Somewhat less important for turbos.

In NA headers you have two options: long tube, or short tube (or long primary/short primary). Longer versions of both move the power curve down the RPM range, reverse for shorter versions. It's generally accepted that long tube headers make more power, but you're looking at VERY long distances (RX-7 needs 90"+), so short tube headers (about 30" for RX-7s) are more common and still make good power.

^What he said.

Velocity and pulse efficiency is the more important parts for a turbo manifold.

Yeah, I was in a hurry so I just threw it together lol It will be shorted 10"-20"

LOL No need to worry about that, it's got K-Sport coilovers now. As you see it in the pics it ran 11.8 with stock suspension and some slicks.

Updated header design, with flange and collector!

not sure you want the merges to collector with flat sides.

Hmmm, is there a bit of room to re-shape pipe #4? Add a gradual curve in the 2nd section to get the pipe running more parallel under the other pipes, that way instead of one 120 degree bend down low, you can do a similar thing with 1 45, and 1 90 degree bends, and while doing it make pipe 4 longer to math the other pipes more closely in length

I'd have #4 go over #3 and into the spot on the collector currently occupied by #2, leaving the long straight initial section of #2 but having it tuck back in to go to #4's old spot, but that's purely from a "lessen the bends" point and doesn't take firing order into account.
