Trying a different image hosting service. Let's see if this works. I made some small changes. First I swapped in an underdrive alternator pulley. It doesn't really need to be underdriven but I didn't like that my other one had a different belt spacing. I was afraid that would lead to...

I'm over 300 miles now. I can't wait until I hit 1,000 miles and start incrementally increasing engine speed: 6,000 RPM at 1,000 miles, 7,000 RPM at 1,333, and so on up to 9,000 RPM at 2,000 miles. I may ultimately go higher than that. It depends on where the car stops making power. Hopefully...

Passed 100 miles on the break-in a couple days ago and am nearing 150 now. It's definitely starting to idle/cruise a little smoother now. Generally keeping engine speeds below 5000 RPM and I don't think I've done more than 30% throttle. Overall it's driving well. Moderate throttle changes are...

I broke down and bought a new battery. I went with the same size and CCA since it's only $80. Fortunately, the last three times I've started the car it's fired right up after 2-3 seconds of cranking and that's without putting the battery on a charger between runs. It appears 340 CCA is enough...

Thanks. I've come to the conclusion embedding pictures from Google Photos just isn't a thing anymore. It's annoying you guys can't even access the link in my signature though. The album is shared with anyone who has a link so it should be working. I'm actually putting miles on the car now. Up...

Updates: -Trying to coordinate renting a dyno with a well-known rotary tuning passing through the area in early October. -Changed the oil and filter. Went with 10W40 this time instead of 20W50. Oil pressure is still 40+ psi at idle. I'll probably try 10W30 at the next change. -Moved my vacuum...

I give up with Google Photos. Album is shared and I don't see any reason why people with links can't see it. I've updated the first post of this thread and my signature to include links to the albums themselves instead of pictures. Maybe that works... Eventually I will take it to a tuner. I'd...

I edited the post with a straight hyperlink. Hopefully it'll work now. It's great it runs but I'm having a hell of a time driving it. I need to tune it under load but it's so unstable with anything more than 10% throttle or so. It's also hard to keep track of the AFR's, TPS %, RPM, and drive at...

I'm not sure how to embed videos from Google Photos. Does this link work: https://photos.google.com/photo/AF1QipMYj1AWmCbK9VOfteIfcTbSliVo4AskaXp-tGos? Sorry for the noise. The fan had just kicked on. It's idling around 1000 RPM. Anything less and it gets a little rough/unstable. It's quieter...

I got it started! I think it was a combination of too much fuel and the throttle being too open. I backed off the throttle stop to around 3% (was 5%) and immediately the engine started to catch more and more with each start attempt. When it finally caught it idled around 700 RPM and was running...

Damn, that sounds worse than my situation. I'm definitely getting spark at all four plugs and I was getting fuel to the rear rotor. I haven't tested the front rotor since fixing the wiring but I'm getting continuity between the ECU and the injector now. You're using an AEM ECU now, right? Does...

Were your injector wires mixed up too? I know of at least one other person with the same problem. In the end it's not a big deal. It was easy to fix the issue once I figured it out. If I had paid closer attention to the wire colors I'd have figured it out sooner. As far as I can tell everything...

I got the engine and ECU synchronized and calibrated the fuel level sensor on Saturday. Sunday morning I primed the fuel pump for the first time to make sure there weren't any leaks. Fortunately there were none so everything was looking good for a Sunday afternoon start up. I pushed the car out...

I'm getting very close to firing this thing up. The engine is back in the car and it's holding oil and coolant. I powered up the ECU and display and everything works. I calibrated everything except the fuel level input. I attempted to synchronize the engine and ECU but by then I think I drained...

I hit a snag in the build on Saturday. I finally secured the fan shroud to the radiator so I decided to add the coolant. While I was cleaning up, I noticed coolant dripping from the back of the engine where it meets the transmission. I removed the inspection window covers and used an endoscope...

Do you have any pictures of these idle screws? I'm curious since they only method of idle control I have is to crack the butterflies. I'm guessing the screws act like a sort of controlled vacuum leak? I was told to avoid MAP tuning and use alpha-n (TPS) only. The internal MAP in my ECU is...

Do you think a larger brake vacuum booster would help? Unfortunately it doesn't look like you have a lot of room in there.

Very cool! That's something I've thought about doing as well. It's probably best to get the car running and log some coolant temperatures first, though.

Visible now?
