    Well so far the AAR valve is a bust. Not truly familiar how these exactly work, but it seems that it resets itself way too fast. So the valve closes as the engine runs , as it should. I run into the house for a few minutes and I come out and I’m starting over again with a wide open valve. So the bi metal is weak, worn, acting normal? Yes it’s a used one and I cleaned it the best I can, and it was pretty clean. School me!

    N47 Rebuilt and Upgraded Head

    I’d ask 750$ for it and work my way down. It’s not the head everyone is looking for, but it’s ready to go .

    My latest arrangement . I moved the IAT from the intake manifold to intake tube. Attached valve cover breather to intake boot. Also ditched my stepper IAC . Tired of it’s inconsistent behavior. Went back to a AAR valve that’s mounted low on the inner fender . Need to dial it in, but first try I got a fast idle !! I’ve got the AAR on a relay controlled from the programmable on/off outputs on the 3x harness. Did the same with the wideband. Neither will work unless the engine is turning . This way I can keep my ignition in run position to play with the MS and not worry about burning up stuff . Time for more tuning

    Swap out the n-47 for the MN-47

    I’d rig up a driveshaft to drive your oil pump before start up to get everything primed and to check how well that spray bar works

    I hope that wheel cylinder holds! I guess that’s on part I wouldn’t hope it works . I wouldn’t skimp when it comes to brake parts , and yes I know how expensive the early ones are- I own 4858. Looks like it had some decent pitting that would cause the cylinder to be oversized trying to clean it

    I don’t remember , but it was very pricey and the holes didn’t hit the lash pads very well. I have a couple extra spray bars if you run into trouble. I do t use them

    I would thorough test that spray bar with oil pressure. My experience was the squirt holes were misaligned . Just drive the oil pump with a drill and watch to make sure oil is going where you want .

    Wow- great project. That shorty manifold is a bitch to mount isn’t it? I remember having to get the studs just right. Might consider SS heat shield instead of aluminum. Does a better job . So the HKS tank - carb mounting holes didn’t line up? I thought this set up was for Mikuni 40’s originally, or at least all Mikunis would line up. Glad to see you went with programmable ignition, you might save a motor. So this is a stock 2.4? I really wanted to try this project myself , but didn’t think my tuning skills were up to it. I’m not sure many have pulled this off successfully. I wanted to pressurize my CAI, but went EFI GOOD LUCK!
  11. If you run the T-5 you will need the dedicated driveshaft . The DS will have to be shortened at least an inch, I would recommend a custom shaft . Z car depot sells the correct yoke. If you have a custom shaft made you can put whatever flange on that works with the diff you choose. The flange on the ZXT diff matches the T- 5 only. The T-5 shifter mounts further forward so you have to cut your tunnel and maybe modify your center console. Like stated , the shifter chooses are plenty. And these trans shifts very nicely , precise notchyness . Another bonus is you can upgrade later for bigger HP. World Class bits can be swapped in for a small fortune , but it will be good for 600+ HP. Gearing is to ones taste. I like the wide ratio for third gear , but I’m running 3:90 in the back. Makes for a nice passing gear . I can 90+ mph out of third.

    MEGASquirt coil on plug.

    Doesn’t it say right on that paper ? Where did you buy this from? It’s obvious someone has set this all up for you , why would you call them? Looks like it’s set up for batch fire and the paper tells you what driver pins to use . Megasquirt manual does a pretty decent job of describing how to wire this in. Is this what your asking?

    Dyno'd my stock L28ET today - coolant everywhere!

    My Spartan numbers don’t match between gauge and TS . We need to do another session.

    Though the correction curve might be off, this engine ran well and I hadn’t changed anything in that category. Now maybe my battery voltage was making a situation worse. Also could be unrelated like you said, and as I mentioned I didn’t like the easy the TPS was acting. Giving my back a break until new TPS gets in. Maybe get a session in next week
