Another swap on my mind

328FTW · 05-09-2009, 06:23 AM

Once again I can't leave things alone, I got a 20V for $100 minus the harness, ecu, exhaust and flywheel. I got another one for $50 with the headers and the flywheel with a good clutch. Brought an auto toyota levin silvertop harness for $50 and pulled together a bunch of temp sensors etc from my parts bin now I have a damn near complete 20V that I want to swap.

A couple of issues though, from what I've read an auto loom really needs an auto ecu. The plugs are different I believe, Now here is the first question. Can I modify the plugs to fit a manual ecu if I have to? I can't remember if one is a 2 plug and the other a 3 plug. And if not are the fuel and ignition maps the same so I can just bridge the park terminals so it starts and run it that way, it is how I did my 4agze when I built that and it works fine.

Also the "uncut" loom was uncut for the most part but for some reason they cut off the alternator plug and left the wires hanging. I have an alternator with the smaller later style plug (the one that's not round like the old bluetop one). I will try to get some pics up but I need to wire that back up so need to get a pic of what wire colour goes where.

I am noob with the 20v swap because I don't deal with them that often but now I have one I want to swap out my old cars 16v bluetop that has done 2 seasons racing. I will pull it together just depends on how much swapping of bits I need to do. Until I sort out what I'm doing I'm not going to hack up the harness in case I find out I need a manual one.

The engine was also missing a tps for whatever reason and I am looking for another one. I think I remember that one off some other model of car works, was it a camry 3L? idk. Finding a silvertop tps is tricky because nobody wants to sell them separate from the throttle bodies because they get more that way. I'll ask my friend to see if he needs/has his from getting the TB off another engine.

you need the tps from an 94-96 supra tt, they can be had new for as little as 75 shipped.
