(**FI-UPDATE POST: 005**) Hi all! Good news: still working on the project ;) I am currently working through setting up the fuel system, surge tank and TBI. This isn't a full update but I did want to show y'all these: adptr.jpg manifold.jpg side.jpg front.jpg What we have here is a successfully CAD'd...

(**FI-UPDATE POST: 004**) So if you’re going to fuel inject your car, you need a trigger wheel/sensor combo for the computer to read. I won’t go into the fuel injection principle-side of things (lots of info out there) but there are a few options for the 3A or 4A…mostly thanks to the following and a...

Haha, yesssiir. I had no shame...i zoomed in on that! :D Actually after doing about three, 1in long welds, i took the weld length down to about 1/4in runs. I was really concerned about warping the ring so i turned the amps up to about 140 (really hot) and did super short runs. the end result was not...

I finished the trigger wheel! Summary video of the build process:

Write up to follow soon...

adding fuel injection to this obsolete head configuration would help some, but you really need to up date the head design with the several 16 valve head configurations that will fit on the 3a (and 4a) engine block. that means not just covering to EFI, but also a whole new exhaust header and system ...

That's pretty sweet, I've never used silicon bronze (although I've watched enough Welding Tips and Tricks videos on it). I went through the hassle of baking/welding/baking/welding/baking/welding to plug up the intake manifold hole on my stock manifold. It took awhile and I definitely learned a lot ...

This is OT, but ... What a nicely organized shop and sweet equipment! Sigh, for us who have but a driveway ... Your car is just sweet! Props! Tom M. Thanks a bunch, sir! I am a Craigslist vulture, lol. 95% of everything i have i got off Craigslist. The rest is pretty much Harbor Freight, Amazon or ...

(**FI-UPDATE POST: 002**) Manifold: On this week’s episode…the 3A exhaust manifold The manifold on the 3A is almost** set up for fuel injection. As mentioned in my previous post, the 3A is a computer controlled carb’d engine. As such, the 3A in my SR5 came with a stock 02 sensor and an exhaust manif...

(**FI-UPDATE POST: 001**) Hi All, I decided that I am going to convert my ’85 SR5 to fuel injection. Out of respect to the many folks who have posted their build experiences on various items for others benefit, I decided I have to do the same  Some of us may remember this thread: (https://tercel4wd...

Thanks, Petros! I figured the condenser attached on the hold down screw, but didn't want to ground it in case it did not. That third "blue" wire most likely is the test port you speak of. After looking at pictures of dizzy's from various other 3A's, that test port comes out of the same har...

Hi folks! A while back my tach started jumping jumping around. Eventually, it just stopped working. I wasn't too worried about it, but now im chasing down the problem. I opened up the dizzy and had a few questions in the attached photo. 1. The FSM does not name what the "floating" thing is...

Folks, I think it's fair to say that if your tranny has above 200k miles or even 300k; it's not really accurate to say that 5 vs 4 is the culprit for failed synchros or related woes. It may be a factor, but the longevity of the tranny has more to do with driving style and REALLY whether you change y...

Update:

For xirdneh's cross reference of the 4 seals from Colonialseal.com, see this post

For what its worth, I ordered all "AS" style seals and will update if I have any issues.

Big thanks, xirdneh. Another trans saved by your post! For what its worth, I ordered all "AS" style seals and will update if I have any issues :) Since paper gaskets are not available as a kit, do you prefer to use the "Gear oil resistant" RTV ( such as Permatex 81182 Gear Oil RT...
