Didn't have much time today. All I did was finish cutting/tacking the final Clamp and locate the BOV. This is the final design..now all this will go to the aluminum welder on Monday...:)

Cheers!

A small update. I actually decided to weld my own aluminum and its not as pretty as if I paid someone but I am very proud of the fact that they are my welds. I also worked on the Upper Radiator pipe using some stainless. Came out good. I then wrapped the Downpipe.

Cheers!

Quick update...found a simple but effective way to mount my FPR using a spacer and began running the fuel lines. The list is getting smaller...ETA is looking like Wednesday for first start with the car driving sometime next weekend.

Cool. That sure makes it easier compared to the REW waterpump, I wasn't aware the RX8 pump spins in the other direction :)

Im 95% done with everything on top...UIM, throttle, turbo, Downpipe, Harness, Heater/Rad hoses, etc have been installed permanently. Now Im waiting for the radiator water tank (should arrive tomorrow) and then I have the stuff under the car (starter, O2 sensor, joining Downpipe to Midpipe etc)...Just an evening or so more...

Cheers!

Just a quick view of the wastegates from the passenger's wheel well...Tight, but not as tight as it looks...they have good clearance all around...Soooo dificult to install...lol

Well....it started this afternoon but when I came back 4-5hours later I couldnt get it to start...:(

I'm thinking it was so rich on that first start that I flooded it...I will try again tomorrow...

For now, here are some pics of the radiator reservoir that came in today and some of the car finally on its feet...:)

Well it wasn't that smooth because I will not start again LOL...I think it got so flooded that the spark plugs fouled and now it won't do anything...it was dripping fuel out of the spark plugs threads (they were only finger tight)...

I think new spark plugs, plug wires etc, are in order....along with fixing the tiny pin hole leak of coolant from my modified water housing outlet :/

I will keep at it this weekend and hopefully will get it finished sometime early next week...

Alright! It moved under his own power...its loud (the exhaust is not joined yet)...but all leaks are acounted for and fixed and it drives...now to work out all the little details...

Quick Update...It only took a few miles of driving to realize that the amount of air that the OEM RX-8 throttle body allows through for idle is not going to cut it on this motor...So I decided to start work on an "idle control needle" of sorts using a pneumatic flow control valve. In case you are wondering, being as though the RX-8 is drive by wire, there is no idle control motor or bleed valve on the throttle since the OEM ecu decides where to hold idle. This is a problem because where its deciding, it wants to shut down. After all was said and done, it worked flawlessly, just enough air to allow me to adjust idle up to 1k-1.1k rpms if needed. Now I can adjust idle speed with the twist of the little knob on the valve. I ended up leaving it at around 850rpm.

Cheers!

That looks really good, so does the valve open with the throttle?

Thanks!

The valve does not open or close with anything. It doesn't need to. All that its to do is bleed air from before the throttle to behind the throttle, enough air for the engine to idle. So basically, you screw it in or out once the engine is close to tune and then you lock it ones it reaches the desired RPM at idle.

Chris

ChrisRX8PR 05-15-12 11:07 PM

Here is a short video with the Idle needle fully out...I later found out that the Throttle body was disconnected and that explained the high idle...It now sits at 850rpm...

I love what your doing man! the rx8s dont apeal to me as much as the fds or fcs but still interesting! wont you be losing power and a lot of stuff by not using the origonal motor???

dznutzuk 05-16-12 04:32 AM

Yeah I had the same problem, I just used the Haltech Idle speed control instead.

damic 05-17-12 01:27 PM

That's a nice hack :D software is for dummy's hardware for the users.

Lol... Only reason I did the idle control that way is because the factory drive by wire throttle is not controlled by the microtech and it has no way of adjusting idle besides the oem ecu...there is no idle speed controller on it. :)

dznutzuk 05-18-12 01:35 AM

Chris, doesn't the Miccrotech have some kind of idle speed controller?

ChrisRX8PR 05-18-12 08:59 AM

Yes it does but being as though I hooked it up through the RX-8 harness which doesn't have one and the fact that this bypass proved simple enough to make I just went for it. If it gives me any grief (varying idle with temperature etc) I won't hesitate to install an idle speed control motor. At the moment I did not have one to install so I went this route.

Cheers!

dznutzuk 05-19-12 01:54 AM

Aha, I see, well if you do get one see if you can use a 4wire GM unit, it's much better than a bac valve.

Ahh I see, sorry I dont know much about engines. But its intereesting some of the things people do.
