    Dropped off the bumpers to the vinyl shop and picked up some Redline MT90 for the transmission on my lunch. Need to pick up some Stainless machine screws on my way home, then I'm all set for a busy weekend!!

    Jen what's your opinion on header heat wrap on ceramic coated headers?

    Not sure - my downpipe is an old one (and a bit rusty), so it definitely wasn't coated. I suppose it depends how close it runs to other things - do you need to keep the heat off of nearby stuff, or can you let it go.
    My Exhaust Gas Temps can run from 1400-2000*F, so I have a heat problem. :lol:

    Need to install the driveshaft, hook up the exhaust, and do a couple other things with the transmission (shifter, speedo cable, etc). Then, connect all the wiring in the engine bay, make some stainless AN lines for fuel and oil cooler lines....soon time to fire it up for the first time.

    I guess the only thing that may happen is it crack the coating. I am not putting a heat cover over my turbo because I don't want to crack the turbo housing, but I may build a little heat shield above it to keep the other stuff cool. I know I have a manifold on another engine that's ceramic coated and it seems to have cracks in the coating, even after not being wrapped.

    I'll find a pic of my setup in a bit and show you. I worry since I'll be having heat issues from the start

    Yeah, I know I'm going to have them too, which is why I'm doing a few things right off the bat - rotaries inherently have heat issues, but at least we have a little more space.

    I should mention, I have no Mass Airflow Sensor because I'm running a standalone ECU that uses VE tuning.

    Update from this weekend:

    - Tried to start it Thursday night, had a short at the starter
    - Fixed that on Friday night, got the car started, big exhaust leak, oil leak at the oil cooler, and the timing was off, but it started.
    - Saturday - fixed the oil leak at the oil cooler, got the e-fan working, fixed the timing, fixed the water temp sensor, it runs - mostly - need to change some stuff in the ECU to get it to run right and idle.
    - Sunday - Took off the downpipe to fix the exhaust leak (the EGT probe wasn't sealing right so I removed it) and made new gaskets for it. Also re-installed the Bypass Air Control valve, which helps control the idle and re-wired something on the fan, put on brake pads on one corner of the car :lol:

    - Tonight's plan: Re-wire high speed on the fan, see if we can get the ECU dialed in a bit, maybe start vinyl wrapping


    Updated to-do:

    - Finish setting up the ECU
    - Finish installing brake pads
    - Clean up the car - interior and exterior - reinstall all interior trim
    - Finish new lexan headlight covers
    - Have it vinyl wrapped
    - Install RE-Amemiya front bumper
    - Install S5 tails
    - Install S5 rear bumper and moldings
    - Reinstall rear window in the top - I have decided to get an auto glass guy to do this while it's being vinyl wrapped
    - Rebuild passengers seat
    - Install seats
    - Alignment (booked for April 11)
    - Install rear diffuser and side skirts (4 hours)

    Here's how she sits now:
    [​IMG]

    Had to put the idle valve back on
    [​IMG]

    Some body parts showed up!
    [​IMG]

    I got a little distracted for 2 weeks in North Carolina.
    [​IMG]

    Gratuitous shots of new body parts and mock up of the side skirts for fitment - needs a little adjustment but very very close.
    [​IMG]
    [​IMG]
    [​IMG]
    [​IMG]
    [​IMG]

    Next I need to figure out if my timing marks are correct, long story. Then get the ECU set up so the car will run right.

    To do:
    - Re-wire high speed on the fan
    - Figure out timing
    - Fix exhaust leak at midpipe
    - Figure out ECU tuning
    - Fit the sideskirts, then prime them and get ready for wrap
    - Finish installing brake pads
    - Clean up the car - interior and exterior - reinstall all interior trim
    - Finish new lexan headlight covers
    - Have it vinyl wrapped
    - Install RE-Amemiya front bumper
    - Install S5 tails
    - Install S5 rear bumper and moldings
    - Reinstall rear window in the top - I have decided to get an auto glass guy to do this while it's being vinyl wrapped
    - Finish reassembling passengers seat
    - Install seats
    - Alignment
    - Install rear diffuser and side skirts

    Ordered the new pump for the intercooler system today....trying to get a few parts together to finish some things.

    However..........IT RUNS!!!!!!! I had a tuner staying at my house last weekend and he worked some black magic on the standalone and it happily idles. :)

    We did find out the water temp sensor isn't working right, reading too low, so I need to figure that out or recalibrate it.
    Going to take the rad back out this weekend and start putting in the upgrades to the intercooler system. Also need to seal up the fuel sending unit - had to take out the pump because I wasn't getting fuel for some weird reason, but then it started working - suspecting I need to check the vent.

    I've had them corrode/stick and moving them around was enough for them to start working again

    Well, it's a brand new fuel pump and everything, so who knows. Seemed to work as soon as I took the seal off the sending unit (and it hissed when the first screw came out) so maybe it was under some vacuum from a blocked vent.

    oh weird - I guess you could likely test by releasing the gas cap too if it happens again

    Weird part was, I had opened the gas cap to put gas in it from a gas can just minutes before and it still wasn't pumping.

    Turned the key, pump ran, no fuel. Put more gas in, turned key, pump ran, no fuel. Took off hose just before the filter (to see if it may be a clogged filter), pump ran, no fuel. Took out pump, and ran it, it spit out fuel. Put it back in the tank with a long hose in a bucket, turned the key, lots of fuel. Blew some air through the line from the pump to the filter - nothing really came out. Hooked the pump back up to the line, left it off the filter - lots of fuel. Hooked everything back up and the car fired right up.
