Olli, could you take some pictures of your exhaust manifold before it's bolted on? I'm running the same GTX 76mm comp wheel as you on a hybrid greddy turbo on the T25 greddy manifold. Yours should definitely produce more power from the higher flowing hot side, but will still be interesting to compare results.

I will today a few pictures for you. Ok cool , we will have nearly the same setup.
Which injectors and fuel pump do you use? I build last year a return system with a deatsch werks 340 L/H fuel pump

I used a Deatschwerks DW200 fuel pump. Part number 140115, flows 255lph. That's a pretty common unit, and runs nice and quiet. In case you're not aware, if you run a higher flowing pump it can overheat the fuel and pump, so if you find yourself with pump issues, this could be it. May not be a problem with a return system though.

I'm sure we'd all be pretty keen to hear about your return system. Maybe you could write some detail on your build thread when you get to it! I'm running the stock returnless system currently, which tends to see fuel starve with less than a 1/4 tank of gas when cornering fast.

Regarding injectors, I'm setting my system up at the moment. Yellows in the P1 position (replacing the reds), stock yellows in P2 and Bosch EV14 1000cc injectors in the secondary position. The Bosch injectors are supposed to be excellent, but don't come with a latency table, so they're a bit of an unknown quantity at this stage, though I should have some results in a few weeks. The more common Injector Dynamics 1k injectors have an RX8 latency table available on their website, which makes them a good easy option. I've been told that the Bosch are a better injector, but this remains to be proven. Uncapped yellows are another option for an injector upgrade, though the spray pattern isn't as good, so fuel economy and possibly performance may suffer.
