Im looking for someone I can possibly get a DCOE type intake kit from that might possibly have a clue about base jetting for the carb and application (street ported motor). I am aware RB is selling the IDA carbs, but Im looking for pricing on DCOE kits also (besides MazdaTrix).

I have a RB street port Holley kit that Im not sure I want to run now, since I used to run a 45 DCOE on a stock port motor and dont really feel like learning all about the Holley, as well as a few other reasons. Ive been out of the game for about 7 years, so I dont know if the old vendors are still around, new vendors are out, etc.

Also, I noticed that on my Holley intake, there is a little extra metal welded on the top side of the manifold to cover the street port intake ports on the center iron - does RB do that or was that the previous owner?

If RB does it, I presume something like this may have to be done on the Weber intake setups as well since those center ports get enlarged so much. Either that, or is it just a coincidence my ports are that big and the person before me had do do it also (the outline of the old ports on the RB intake are about the same size as my intake ports).

Anyway, any info would be good. Thanks in advance!

Rotaryshack has them. I think there are several people with dcoe setups here... Installer67 I believe. But I think he actually started a massive thread on the subject kinda recently. He has tons of info on jetting in there too. And Hyper4mance can jet a weber in his sleep. I think has only run ida's but he might have a thread floating around somewhere with dcoe stuff in there too.

To be honest, I don't think you'll have any luck with a baseline jetting from anyone, since streetport's jetting differs so much from individual motor to motor. A lot of people have started with a cookie-cutter baseline jetting for stockport motors with good success for a starting point. Not so much luck for a baseline streetport jetting. too many differences between ports

 

Ooo http://www.webercarbsdirect.com/ and http://www.redlineweber.com/ has them too

rotaryshack's prices are better if I remember, and they will baseline jet it for you too, I think.

 

Another vote for Rotaryshack. They hooked me up with a 45DCOE on my stockport.

 

Well, to be honest, Rotary Shack was where I got my first setup from. I think I was his first RX7 Club member sale back in the day when he was trying to move away from the dark times of his former business partner. I sent him an email tonight, I just didnt know if he was still around since his old user name seems to be banned. Thanks guys.

There is some sort of yearly fee as a vendor on the club forum. He quit operating as an official vendor on the forum, so he doesn't pay the fee. Hence the "Banned! I got owned!!" thingy
