Contains detailed setup and tuning info.
I've spent my summer researching and saving/ spending money on this project. I have a 73 mach 1 with a 351c, and it's been sitting since I picked up my crossfire as a daily. The crossfire does everything better than my mustang, its faster, handles better, is safer, more reliable, better on gas etc. I figured its about time to do something about that and started getting a taste for turbos. I realized a blow-through carb wouldn't cut it for my application, because I would like to be able to daily drive the car and drive through NYC to Englishtown, race and drive home. Megasquirt is probably the cheapest way to go injected, but there is alot of learning involved, which I love about it. Enough with the BS though
So far I bought the DIY MS2 kit from Glen's Garage with a wiring harness, stim, Coolant Liquid Temp (CLT) sensor w/ pigtail, Inlet Air Temp (IAT) sensor with pigtail and relay board. (~$500). I bought a prototyping board from radio shack (Blank circuit board to make circuits with) and a bunch of resistors to practice with (~$5). Once I felt comfortable soldering I put together the main board following most of the instructions
. After fixing my mistakes, I started hoarding parts.
-MS2 V3 w/ mostly assembled harness and relay board.
-8 Bosch / Ford design 3 low impedance injectors. (Bosch PN 0280155715 Ford PN F50-E85A)
-GM style CLT and IAT
-MSD ready to run distributor and 6A box.
Megasquirt will use the orange wire off the distributor to sense engine position. The Hall Effect circuit is used on MS using the points (no coil connection) circuit. MS will control the ignition via the white wire on the MSD box. A standard MSD with the purple and green wires uses the VR circuit in megasquirt.
-2000 Northstar throttle body with throttle linkage removed and re-welded to allow the cable to pull from the back. (Same as LS1 TB but backwards for FWD) It may not make sense, but the junkyard had one for $75 complete with TPS (Throttle Position Sensor) and IAC (Idle Air Control) solenoid and it is 74mm stock.
-Universal injector harnesses and bungs
-Weiand X-celerator single plane (PN 7516) Machined using a CNC mill.
Can be done on a vertical mill (Bridgeport). A large block of aluminum was used under the manifold in order to clamp it down to the bed of the mill. The block was tapped in 2 places in order to thread in studs. The studs were used to hold down an aluminum bar across the top of the manifold.
-36" 1/2" Universal fuel rail cut in half and CNC machined. We made a program in Mastercam to cut pockets for the injectors. The spacing of the injector bungs on the manifold is identical to that of the rail.
-Edelbrock TB to 4150 intake elbow (PN 3848).
-Edelbrock adapter plate (PN 2737)
-Bosch "044" fuel pump (300 lph)(PN 0580 254 044)
-Aeromotive -6 return and boost reference style fuel pressure regulator. (PN 13109)
-Aeromotive -10 100 micron fuel filter before the pump
- -8 Russell fuel filter after the pump (PN 650103)
-New fuel tank and straps to weld a sump (Comp Engineering 4041 1/2" NPT outets) and -6 fitting for the return line.
-15' of -8 pushlock hose (feed) and 15' -6 (return) using all black fittings
-AEM wideband o2 gauge/ controller (PN 30-4100)
-Electric fan controlled by MS' FIDLE pin and relay
-Dell Latitude D610 from eBay, nice cheap computer that I bought just for tuning but I'm getting alot of use out of. It was $250 shipped as a refurb from Blair Technologies Group.
-Mr Gasket fuel pump block off plate (1517)
I still need a couple things but thats the bulk of it. There's no point in sharing what I paid for some of the stuff because I got it at a discounted rate from the store where I work, I don't know what they retail for
. I will get it running NA first then eventually move on to a turbo setup when I'm comfortable tuning the car.
