z31t Posted October 4, 2011 Share Posted October 4, 2011 Hello everybody my name is Felix and Im in the middle of a 1jzgte swap into my 77z as the title states. I really want to stick with the stock gauge cluster and I have already got the oil pressure and water temp gauges working but Im having trouble getting the tach to operate. I tried searching and can't find any concrete answers that I haven't tried already. Here are some pics of the car the day I started it up and took it around the block. The hood isn't on because I'm waiting on a 90 degree fitting for the oil line so I'm riding around getting the bugs out of it like this. And my other cars so you know Im a z nut. The red one is a sohc vg30 that makes 620whp and the other is a stock lowered shiro in need of a front lip Thank you Quote Link to comment Share on other sites More sharing options...
slowsupra Posted November 27, 2011 Share Posted November 27, 2011 The reason the Tacho won't operate is because you have a tach that is designed for a single coil input, but you are using a coil on plug type ignition system with multiple coils. You will need a Tach adapter from MSD or Dakota Digital(I prefer this one). Wire it in, adjust as needed and you will have a working tach Quote Link to comment Share on other sites More sharing options...
z31t Posted December 20, 2011 Author Share Posted December 20, 2011 Thank you for the response, I've tried the msd tach adapter because I had one lying around the shop but the dakota digital unit you referenced looks promising. I've got the car running about 17psi now and making 440whp but I would still like to get all these small loose ends tied up. really happy with the swap overall, its a ton of fun on the road.
