On my last build I used EA82 head studs on the EA81. Studs torque better than bolts. Steel thread on Steel bolt vs Aluminum threads in the block.

Photo dump. Check back for descriptions. Ford Edis control module I used a fuse as a means for a jumper. The module can run independent from the micro squirt when the jumper is removed. Mega squirt has info on their site of where to get parts at pick and pull or new. Crank wheel came from 98 Ford ranger. easy machining on the lathe the make it fit the Subaru crank pulley. Of i has to do it again, I might buy the wheel from DIY auto tune. Mounting the sensor is tricky. The only bolts near the crank pulley are the oil pump, and those need to seal. So I bolted to the large bolt on the head and on oil pan. Mixed and matched to save money. I got some parts from DIY auto tune,. Rock auto and pick and pull. I'm in for about $600

Keen eye skishop! I have actually tried 2 different wire configurations. MS tach output to yellow (ECU + Tach) and the 3 way splice. (Dizzy output + MS tach output to ECU + Tack input) That makes sense with the difference in signal coming from the dizzy vs MS. Next I will try clipping the MS tack output and just feed the ECU with the Dizzy. Bratman: I chose Microsquirt V3. It looked like the best bang for the buck. Thanks for the diagram but i cant read the wire colors.

Attempted to fix the Diagram photo.

Here is the wire diagram, I am using. Modifications are written in in pencil near the ignition coil. Wire Modifications to the Subie Harness at the old coil location. Including the mystery Grey wire with loop.

I know a few folks have dabbled with this but it does not seem to be well documented. I'll build this into a write up Once i get up and running. I Got my Microsquirt wired in. I'm starting with ignition only. Ford EDIS with VR sensor on Crank. I used power from the coil to close a new relay for the EDIS and Megasquirt. (black-white) I spliced together the Yellow Tack wire (subaru) to the Green Tack output from Microsquirt. The yellow wire used to come from dizzy and and go to the ECU and Tack. Fuel pump does come on. My tach bounces while cranking but I am NOT getting the injectors to open. Tuner Studio also sees the crank spinning. Battery is charged to 14v. While cranking the timing light shows 7* advance. (not perfect but close) Any ideas on why I'm not getting fuel? There is an extra grey wire that used to be connected to my coil. It is not in my wire diagram. Does it need to be grounded? Thanks!!!! Photos coming soon!

Thanks! Turbo! I'm going to cut the the center out of the EA81 pulley and weld in the EA81 shaft. Quick work on the lathe. I will be able to keep tight tolerances and produce a press fit. Photos to follow.

I'm at pick and pull now. I see the difference. Na vs turbo. But it looks like ea82 will fit if the shaft size is the same.

Damn. What is special about the turbo pulley?

There is a chunk missing from my crank pulley on the rear v groove. Mine has 2 v grooves. What years / models will be parts matching at the yard??? Anything other than EA81? Must have AC? I'm putting in mega squirt so a repair could cause noise for the VR sensor. Thanks!

I'm getting lost in the alphabet soup. I've been reading for a few hours yesterday and today. I have an Brat EA81 Factory turbo. It looks like the brat is special and got some more ride height than other cars. I'm looking about 1" lift to fix my the tire rubbing after installing 205/70/15s. What springs will lift / lower the car? EA82 4wd ? EA82 2wd ? EA82 Wagon? XT? RX? EJ? Toyota? Honda? VW Golf? I have read all these being used but without the effect on ride height. Is it true EA82 struts have more travel? A lot of folks mention what is working for them but neglect how much lift they got with that setup. Maybe folks can share their hub to fender clearance. Unless you have trimmed your fenders. Thanks!

Is this for the Radius Rods?

I'm getting ready to order a megasquirt kit. There are lots of options. Can folks describe the Options they are using? Wideband / Narrow band, external gauge? MicroSquirt / Megasquirt? Knock sensor? Flexfuel sensor? MAF + Map? Thanks!

Did anyone ever follow through with this? Is there a writeup?

Philbin wants $250 for the REBUILD of the EA81T Vacuum pod!!!!
