Popular Post GARDRB Posted April 16 Popular Post Share Posted April 16 Dad's cousin married Max, who has always been our family mechanic and panel beater. He's somewhere north of 70 and a full-time menace and tinkerer. This is his Ke70 wagon that he bought off @Dudley (also a fill-time menace) and proceeded to rebuild half the body of before painting it and tidying allll the things. He got bored one day and had a 2TGEU sitting around that he'd got in exchange for putting a 4age into someone's wagon years ago. The loom had been chopped in half, and being older than fuel injection he thought it was a great idea to replace the injection with twin carbs. Yesterday my brother called me and said "Max has been talking to Pete's friend who built himself an ECU for his car and tuned it himself. He reckons you should be able to do it." Approximately 24 hours later I have all of the EFI gear from the Corolla sitting on the floor in the shed and have read half of the information on the internet about the Speeduino. I've been given a generous (for a Speediuno build) budget to work with and told to get ordering. I've printed out the 2T wiring diagram which is comical after dealing with 1UZ diagrams and am starting to make a plan. So far the shopping list (other than the ECU) includes: IAT sensor (probably a Toyota one) Map sensor (also probably a Toyota one) (so I don't have to run a vacuum line all the way to the ECU and can just run it off the AFM wiring) TPS (maybe 4age as we have a couple of motors sitting around) A wideband, probably Spartan 3 I'm leaning toward either one of these https://www.everythingfuelinjection.com/store/The-Micro-p161480124 https://kiwiefi.nz/index.php?route=product/product&path=20&product_id=54 Feel free to tell me in the discussion how far over my head I am. I've wired a 4age, a B16a, an SR20VE, a 1uz and a 3uz and used to do car alarms, so pretending I know what I'm doing. 16 Quote Link to comment Share on other sites More sharing options...
Popular Post GARDRB Posted April 17 Author Popular Post Share Posted April 17 So because I have a big job to finish at the moment and am under immense time pressure, I got distracted and had a fiddle in the shed after staying up late last night doing research. This is my 2TG pile. First I had a fiddle with throttle bodies and TPSs. On the left is a TVIS Redtop 4age throttle body and on the right is the 2tg one. The 4age has a potentiometer TPS vs the switch type of the 2TG The 4age inlet manifold is on the left, and the 2TG one is on the right. The bolts are the same width apart, but the 2TG ones have a smaller spacing vertically. There is also a 10mm difference in size between the two TB holes. The nerd that can't weld alloy in me has been working out how to design a bolt-on adapter plate to bolt the 4age throttle to the 2TG inlet, but the logical option is probably to make a weld-on plate that the 4age throttle bolts to. We looked into switching the TPS over, but swapping the whole throttle seems to be less fiddly and results in a bigger throttle, and bigger is better right? The next little mission was trigger wheels. We searched through the shed for old Toyota distributors and found an AE101 5AFE one and a Blacktop 4AGE one. I pulled them both apart and decided the 4AGE one on the right was a simpler setup, but will take them both to Max and see what he thinks. I've read about how ideally you want to run your trigger on the crank due to distributor slop etc, but this seems a whole lot less ugly. Hopefully, we can drop these guts into the 2TG distributor and get a cam and crank signal off it. It will be easy right? (This is what people say when they come to me for website things that don't turn out to be easy). I've found this discussion https://speeduino.com/forum/viewtopic.php?t=495&start=100 that relates to a 3SGTE that seems to use the same style of trigger wheels. 12 Quote Link to comment Share on other sites More sharing options...
Popular Post GARDRB Posted April 24 Author Popular Post Share Posted April 24 The ECU has arrived, consider me impressed. The micro USB is a bit janky, but that's neither here nor there. It's been fitted with a VR conditioner and configured to suit the Toyota 24+1 trigger setup. It connects to TunerStudio which I'm quite happy to see has Mac support. Now I just need to resuscitate a laptop, as I don't think my Mac Mini will work very well in the car. I went and saw Max on Sunday and we stood and stared at the two disassembled dizzies for a while. The guts of the 4AGE dizzy are too big to fit in the 2TG dizzy, so it sounds like there is going to be some sort of choppy choppy sleevey sleevey action going on. We're looking at potentially cutting the 2TG dizzy off at the red line, turning the blue section down and turning the base of the 4age dizzy down to be joined with a sleeve and joining the two dizzy shafts somewhere in the mix. Max also pointed out the oil port on the side of the 4age dizzy for lubrication and told me he was gonna lie awake at night designing something in his head. I guess my next step is to start stripping the 2TG loom down and working out what I'm keeping, what I'm removing and what I'm adding, along with what is already in there that can be reused. I'm already planning to run the map sensor and IAT sensor off the AFM wiring having done this previously on a Silvertop to Blacktop 4age swap, and I know I'm gonna need some more injector and ignition wires. 12 Quote Link to comment Share on other sites More sharing options...
