Thinking Megasquirt again, on the /6, Blame Excellence Options

[Dr Evil]

Scotty B let me read his copy of the latest Excellence where they put a MS derived injection system and put it on a 6cyl motor. The kit was from Bitz Racing, cost $1600 and requires some CIS parts. Looking at the kit I am thinking that I can do it for much less. I already have 2 full CIS systems, I can build a MS, and I can buy the fuel system parts independently.
So you figure, $1600 for an install and run kit --> http://www.bitzracing.com/products/index.html

Parts cost:
- Fuel rail = $10/ft
- Their recommended fuel pressure regulator, MSD-2222 = $75
- Their recommended injectors, ACC-150630 = $230 for 6
- MS v.3.0 kit with everything = $200 --> http://www.diyautotune.com/catalog/megasqu...case-p-108.html
- Injector adapter bungs = $120

Total = about $650

I have not priced an O2 sensor just yet, though.

I would like to convert my 6 into a twin plug monster in another year.

My 911 is a 3.3L twin plug TWM-itb 'monster' w/ Haltech E11v2. A great unit for sure, but the Microsquirt gets my vote today for 95+% of the usability at 25% of the price:) The uS can drive 4inj/bank(hi imped) so it can easily do batch fire like the 3.2 carrera motronics do.

The AEM CoP is interesting. Will they fit? You only need ~4.5" to clear the valve cover and they look to come long enough... Wonder if the boxster/996 CoPs will work. Those are pretty long too. The AEMs look to be ~$60ea but don't include the CDI ignition drivers:( The boxsters are self contained and only ~$55ea. Though a twin-plug carb/itb motor just doesn't look right w/o a big 12-plug dizzy;)

Edit: Mike, make sure you install a TPS. The bitz kit doesn't use one and I've talked to at least one person who had driveability issues that it probably would have solved IMO.
