I'm also looking at Bussman relay/fuses boxes like these:
Much cheaper than a full race spec PDM.
I didn't want to rely on 35 years old wiring that has seen a Megasquirt install and numerous changes in the setup. It looked a bit overwhelming at first since I hate wiring jobs but it's not that bad when you have a proper wiring diagram to work with. The MaxxECU PDM is a bit over the top and...
Getting rid of all the stock wiring except for the headlights, wiper/washer, turn signals/break lights. I also got all the HVAC system out. I will install either an aftermarket PDM or relay box to replace the stock relay/fuse box.
If you line up the crank pulley with the mark on the oil pump casing, lock the cams with the tools and have your cam pulleys line up with whatever the mark is for the year/model that your head is from you should be ok.
Progress is slow... Gotta order some aftermarket control arms for the rear S14 suspension in order to gain some more clearance between the UCA and the rear frame rail. I also need to find a way to install the accessory belt without the PS and AC pulleys. I know that there is a AC pulley...
I just checked the price of the ECU Master Classic and it's way cheaper than the MaxxECU I was planning on using for my build. Seems to have pretty much all the features that the MaxxECU Race has also. I will have to read more on this.
That engine sounds great btw. Very nice build!
