    I got with the engine builder
    For my new engine it is closed deck
    He removed OEM sleeve and milled out aluminum to fit large sleeves.

    Hi Everybody,

    Mark asked me to post on his behalf. I am the one who completed all of the work on Mark's M12. I had it on the dyno earlier this week and wanted to share some progress photos. Im the one who completed all of the mechanical work and the wiring/startup/tune. The only thing I didn't do was the exhaust and misc fab work. I will be glad to answer any question you guys may have. I will post more pics later, this is just what I have available.

    Here is some of the work that has been completed so far.

    Bore 3.535" with 3.38" stroke

    ECU mounted in the cabin
    Dual firewall connectors
    all factory gauges work and coolant temp gauge doubles as a check engine light

    Notable chassis upgrades:
    Removable driver side chassis brace for trans removal
    Ron Davis radiator with revised mounting to remove the stress from the radiator
    Aluminum Coolant tank
    New fuel pump wiring

    Im not sure why some of the pics came in small. I will try to take some more detailed shots this next week. We had some breakup on the dyno and had to source some better and colder plugs. once we got those in we were able to run the 14psi. It was the end of the day so we had to stop there. next week we are hoping to see 500whp. Then Mark will put some miles on it before we dyno with E85.

    Nice work.

    Looks like you really want the steering wheel pointed straight when the car hits 3500 RPM.

    What are your thoughts on the AEM ECU now that you have the car running?

    I really like it. I use them quite often. I've been using them for quite some time. I've put them in a fair amount of cars too, 2 Rotor/3rotor RX7, 2.7/3.0 + a GT2 Swap in a 911 Porsche, 69' Camaro, some LS applications, BMWs, Hyundai 2.7l I4 + 3.8l V6, Ecoboost mustangs... they can do quite a lot. The fuel model works really well. The Duratec V6 is quite easy compared to some other custom applications I've worked with. The way I did the DBW made the conversion really easy. We still have plans for traction control but didn't want to overwhelm this project too much right now. Most of the wiring is in place, we just need to mount some speed sensors.

    You can get a Infinity 506 to go in a Noble pretty easy. If I can source an ECU header I can make a PnP. If not a repin would be too hard. Or if you want to add a fair amount a new harness is pretty easy too. Is it common for Noble owners to remove the MBE?

    Not yet, but...

    The ECU is password protected, and the ECU is no longer in production. I dont know what features it has as I dont have the password.

    Frustrating that the pimply faced kid down the street can get his WRX tuned for this altitude (I live at 5500 ft elevation and be at 10,000ft in 30-45 min) at a handful of shops within a 30 min drive and I have two or three people in this country that can do mine, and that requires me taking the ecu out, and sending it to them. And if the tune bricks the ecu...

    I think if there were a cost effective solution, it would be more common to swap them out.

    What do you consider "cost effective"?

    I have converted a couple of nobles to the Ford ecu and they run great, no altitude problems

    I'd love to continue this conversation. I'd prefer if we moved it to a new thread. I do to want to hijack Marks thread.

    Any updates or impressions on the new set up compared to the old? Seems like this is the only thread I can find with the Nautilus big bore engine
