RNR, Full Race and Ebay 02 housing testing by Buschur Racing
jbfoco,
Please READ what I type. I did adjust AFR's AND boost levels.
RNR, I am surprised and honored that you want me to test something else. That to me means alot as you must think I gave it a fair shot. Thank you for not assuming I am trying to cheat you or anyone else. Thank you.
I didn't know you guys made an 02 housing. I'd love to test it, if you'd like to send it I will test it. It's an easy swap. We did all the swapping of parts on the dyno today without every even loosening a strap on the car. It was so much fun doing the testing that I didn't realize from the time we started until the time we finished was 5 hours!
This Ebay piece, while it did make power, surely can't last very long. It just isn't built heavy enough. I have heard of them breaking/cracking in the past but didn't care then. Now that I see it actually works I am concerned about it. To be honest, I figured anyone that bought this cheap crap from Ebay deserved to have it break! haha
The Full Race header is heavy, so is the RNR. Both pieces I would say are built to last. I use the same material (alteast it seems to be the same) on headers I build here. Very good stuff, very thick. Both headers had very good welds and internally the tubes were both slag free.
I don't know how much the ceramic coating helps. In the case of this testing I would say very very little. The fascia on my car was off, so the air filter and FMIC both got a good high flow air to them from the fans. The hood was also open. The ceramic coating shines in keeping under hood temps down, in this case it just wouldn't matter. I like the coating just because with it the turbo assembly doesn't get rusted from the built in BBQ grill Mitsubishi built into the hood. (BTW, the wing is the picnic table, car is very camper friendly! haha)
Monday if we get time we will be testing a few more parts. Depending on the outcome of the tests I may or may not be able to publically post the results.
Oh, looking at the rest of the headers on the market, Meagan, Ebay, GT Spec (which I tested) I think those headers are going to perform all about the same. The GT Spec header was very heavily built, short runner, perfect fit, easy to install, ceramic coated and off the top of my head performed very closely to the RNR header. Small loss in low/mid range power and close to the ported unit on top. I don't see any sense at all in testing all these short runner headers that are basically copies of one another. Hell the same child labor probably welded them all together and just rebadged them
The DC Sports header I had ordered close to a month ago I was looking forward to testing as it looks like an exact knock off of the Ralliart header. Short runner but close to equal length. Fact is I can't wait any longer as I wanted to know this all out in one shot, like I did. It is still on back order. We cancelled the order today.
I'd like to test RNR's 02 housing and Works. I'm fair so if either of these guys want to send them I'd be glad to do some testing all the same day.
I returned the header already via UPS to the customer that sent it to me RNR so I can't bolt it back on.
I still have the Full Race header, I have to call Geoff and see if he will sell it to me. Myself, I will probably keep the stock ported/coated header, even at a loss of a few HP. I like our SS heat shielf look and besides the DSM/EVO shootout doesn't allow headers in the stock appearing class and that's where this car fits.
Thanks for all the support guys.

i don't know how anyone from the Evo community can dislike David. He is the MOST HONEST person i know in the industry!!! Tho he is in business to make money, he does it in the utmost honest way.
For you haters out there.. i don't know what the heck you're thinking?
David, as always, thanks for all the FREE information you give all of us even tho it doesn't benefit you one bit and probably even cost you money! KEEP UP THE GREAT WORK!!!
Btw, i knew my Ebay 02 housing on my old Evo was making all that power!

this is the best post i've seen since i've join this forum.
i had no doubt on Full-Race, i know they would come through. they have been supporting the Honda community for a very long time and regarded as God. i was not aware that they were coming out with a manifold for a stock turbo. this is great news, i'm very interested in getting one. would you by any chance have pictures of the Full-Race mani, it seems that they don't have pictures of the new mani on their site yet.
any chance you could get a hold of a LoveFab manifold for the test, that's if they have one for the stock turbo. LoveFab

so looks like br stock ported couted manifold and the full race header take the win. david could you tell us how these to differ from each other. meening 1 loses low end but gains alot of high end, or one dosent lose low but gains high. if you no what i meen. i read the hole thread but kinda got a lil confused on trying to match each test to see what dose what and where and the best way to go. hope you can help out.
I used a "ebay crap" (SSautochrome) o2 housing on my old 03 evo along with an EVO 6.5 TME turbo for over a year without cracking.
Dave, how much do you think you could sell a tubular O2 housing for made from material that was thick enough you would feel comfortable using it? The thin wall E-bay ones would probably undercut your price, but the thick wall durability could be your selling point.

Then, after putting on the Ebay O2, the Full Race mani was less restricted and showed 4.1whp/3.2wtq over the Buschur mani:

Again, the lines were almost identical, but the Full Race mani had more power near the top.

Keith,
I bought that housing from Ebay a few weeks back and sent an e-mail to the guy, so did Jarrod, to try and see if we could buy more of them a time with break in price. No answer for either of us. I didn't know if it would work or not but if it did wanted to try to buy them to resell. Honestly, there couldn't be much profit in it already.
After not getting an answer I pulled out the jig I built for making EVO O2 housings last year. (Remember I built a couple for using an external wastegate.) After about 30 minutes of getting pissed off I quite. The bend is SO tight that they are VERY difficult to make. Add to this that the bell mouth for the wastegate port is SO big it just makes it more difficult. It is truly amazing that the piece can be bought for $80. I was thinking of just buying them at that price and re-selling them shipped for $100. In the end we don't make squat on our ported/coated piece anyway. The coating costs us just under $100 per piece, we have to ship them out 10 pieces at a time to get that price and then ship them back to the shop, plus we have well over about 45 minutes in getting one ported. I figure that we MIGHT make $20 on each one of those ported/coated pieces we sell. That isn't very much profit at all.

Is there a way to change the main topic that comes up on this thread? If a moderator could make it reflect "RNR, Full Race and Ebay 02 housing testing by Buschur Racing" I'd appreciate it. I keep editing it but just realized it doesn't change the main topic that you see under "engine turbo drivetrain".
Sorry to be a bother.

This has been a very revealing thread, thanks for all the effort David. The only missing piece of this puzzle is; what is the difference between a stock unmolested exhaust manifold and the Buschur ported manifold? If there is a difference between them it would give me the information to decide if I want to go tubular or ported since the gains are close. If there are no gains between stock and ported/header manis changing the 02 housing would be the only part I buy.
