Anyone tried the NA OBX headers?
 

Saw a set for sale and was wondering if anyone has these or has tried these. Any comments welcome. Also, anyone know approximately what gains are acheived with headers?

How Much Are ObX
 

I Wanted to buy OBX ALSO ARE THEY ANY GOOD .. I HAVE A AVERY SMALL BUDGET . .

a while ago i raised this question about these headers. from ebay right? i am going to get them, just my budget at the moment is tight. as i can remember, we compared them to the pacesetter ones for the NA supra. I personally like the OBX headers. they look really clean, the welds look really good and it looks like an overall good product.

Dang, I was hoping you would have gotten them by now. :bouncy: Their build quality seems really nice, they are what I would go with if I had an NA, Most definitely. http://www.toyota-supra.info/forums/...hlight=headers

I got a reply from one of the sellers. The outlet is 2.5". Soo... Would it be a waste if you had 3" behind that? Curious...

Pacesetter is a 2" outlet. OBX seems to be the better alternative.

Stick with 2 1/2 or 2 3/4 at the most if your planning to use nitrous. I just did a calculation based on engine size and the ideal piping size is slightly under 2.5. 183.07 is the 7M in cubic inches.

(RPM x Motor Size)/554,177 = Recommended diameter.

(7,000 x 183.07)/554,177 = 2.31"

With those #'s 2.25" is darn close. Have you seen headers with a 2.5" exit?

Yes, and I've seen 3" collectors too. I recommend you stick with 2.5" piping.

haha no, not yet. soon though, very soon. I decided to do a whole bunch of little things first. replaced all my vacuum hoses with the hose technique kit. made a custom intake, so now i dont have that ugly N/A intake piping. and I got my dvd player for the car that i have been saving for haha......

but the headers are my next thing. I am definetly getting the OBX headers. probably within the next month. Cant wait to get them!
