Help with unusual header I.D.(pictures)

[ZX-AE]

This is the header on my 240Z. I know nothing about it, it was on the car when I bought it along with a unusualy tripple carbn intake which I was told was an F.E.T.

Tony D over at zcar.com seems to think it might be a moddified JDM Fujitsubo Racing header, others think it might be a BRE. I figured I'd ask here as well, you guys seem to be more into this sort of thing than the guys at zcar.com.

Sorry for the crappy pictures but it's the best I can do.

You need to talk to Ron Carter. Those look very similar to a new set of BRE race headers (built from information from those that know) he put on his beautiful reproduction of John Mortens 1971 CP National Championship car.

Check his gallery images, or PM him.

With the exception of the front pipe it does look quite a bit like the BRE header. Really the way to tell would be to look at the collectors and how they are set up. When I first looked at the photos above I thought that it was a BRE header but after reviewing my photos I am not so sure.

here is my header:

I'm doubting it's a BRE, the similarities are amazing though. I'm not 100% sure but I dont think my collector is quite as complex as yours, but I will try to get a picture of it tomorrow. The way the exhaust system is designed it splits into two pipes then Y's into one 2.5inch pipe close to the tranny crossmember.

I do know one thing, it's way too much exhaust for street car with a stock N47/N42 280Z engine. But I'm going to leave it on the car, cant wait to hear how it sounds once I get it running right.

I know that there is a Japanese header (mentioned above) that is very close to the BRE design....that is probably what you have. From a performance standpoint it will not be as good as a Stahl header, but it is a rare item, and worth salvaging if possible. I would remove it and have it thermal coated, and run it on your car.

^^definitely looks sexy.....

Theres a bad picture of one of the two collectors.

I was considering pulling it off and having it coated but I dont wanna mess with it yet, I want to drive it. Might get around to doing it this winter.

[Ron Carter]

yeah, the BRE headers are flanged so I think you can rule that out. I understand that you want to drive the car...the cost and time to get this done now you have your car apart to this point is pretty minor...I would really reconsider...but hey it is your car

Is it bolted to the block? It looks like it might be... Or does it use the same kind of setup as on stock cars where it's nut/stud and oversize washer to hold both manifold and header at the same time?

It's bolted to the block and it's the same as any other except the studs/nuts have been replaced with bolts by a P.O. I didnt take them all the way out I just loosened them enough to get the intake manifold off.

My goal is to have it running and driving by the end of next week, I'm going to try to have an FI intake on it by tomorrow. Thats the easy part, the main things I'm worried about it mouting all the extra stuff, the wiring and the EFI pump+surge tank. The car is in great shape inside and out it just needs a fuel system, thats why I dont want to pull the header.

I say leave it on and let us know how it sounds!!

Good luck...

I'm a little over a week behind schedule but I finaly got it running. It doesnt idle but it revs real quick and smooth. I drove it around the block and it has lots of power, I accidently spun the tires pulling away from a stop sign. The exhaust sounds pretty good, I havent driven it enough to say anythign more about it.

If I can get it to idle I'll be a happy little boy, right now I'm thinking vacuum leak.
