I am also using some of Atkins stuff. I have his intake = manifold ready to bolt on, but keep wanting to run the stock turbo that I have. I = am about to call Dave Atkins to get the connectors for the injectors you mention. The engine he sells comes with 2 ’91 stock = turbo injectors and 2 of those that fit his manifold. So I am hoping = that they are close to the 550cc that the other injectors are at. I do know = that they are low impedance while the stock injectors are high = impedance. Will let you know what Dave says.

More than anything, I am hoping that Paul will make a duplicate = of his intake manifold for me (hint hint Paul) so I can have a quality = manifold. The one I currently dreaming up is a bastardization of the stock and the = Atkins with big ugly cubic transition areas. (Please Paul save me from = this ugly fate… make 2 manifolds ;-)

Hi, fellow rotary enthusiasts....I have Dave Atkin's = fuel and ignition system. I am trying to identify my fuel injectors, as Rusty = wanted to know what size they were. All I can find stamped on them are the = following numbers. 171049 and 9211. Anyone have any idea what = brand and size these might be? Thanks in advance for your replies. = Paul Conner, 13B powered SQ2000 under construction.

Hi Paul,

Does your TB say TWM on it? = That's what I got from Dave, but I didn't order the whole enchilada. There's a decent amount of info on the TWM site at- http://www.twmindu= ction.com/Home/Home-FR.html but it doesn't show any injector part numbers similar to the ones you = quoted. Here's another silly question, do you have two, or four injectors? =

I'm still curious to know what you = got from Dave, but I will be ordering a couple of injectors from TWM. = One thing I found out from Tracy was that his = ECU requires 4 injectors of similar size. In other words, you = can't use two 550's, and two 850's like they do in the 3rd gen RX-7's. TWM = sells a Rochester = injector for their TB that's 525 cc/min at 43.5 psi, so I'll get two of those to go = with the two stock 550's that I have for the = primaries.
