SimSoph and Son build thread
This should be fun. After living 20 years without an RX7 I took the plunge and bought a 1979 to rebuild. I found a semi-functional 1st gen in Orlando for $800. With parts and tools I'm up to just under $3K.
The fun part is that neither my son nor I are mechanical geniuses, but I need to show him that with some basic skills and a lot of help from this board, We can bring it back to life as a great weekend driver. Of course he wants it to be his daily driver.
Wish us luck.

Steps so far:
1. Removed tie-rod ends for replacement (purchased new)
2. Removed oil pan for cleaning
3. Removed aftermarket carb and manifold (Holley 600) which was flaming (purchased Nikki)
4. Disassembled and cleaned Nikki carb, not all of the screws on the main body yet
Issues found
1. Purchased Nikki carb has 1 broken Venturi
2. Tie rod ends were frozen but came off with some persuading.
Next steps
1. Clean and replace the oil pan
2. Install new tie-rod ends and new boots
3. Replace front disk rotors
4. Replace front brakes
3. Compression test the engine (waiting for parts for the home built compression tester…Thanks for the plans David)
4. Pray compression is OK
5. Foam the engine to clean.

good luck with the father/son build. my 5 year old daughter tries to help but still a bit young to actually wrench.
one suggestion i do have for u is to use "the right stuff" to seal your oil pan. i've tried permatex gray before without success twice but the right stuff fixed the leak.

It's a strange Holley. I believe that it is off a marine engine. It was tough to find specs for it. I believe that it is a 0-80450 or an 0-80451.
When I picked it up, the car would choke out over 4K and fail to idle. The previous owner botched the emissions removal, I'm working through completing that too.

I'll try to get some pictures up but I'm in a bit of a mess now.
Getting close to running BUT my newly installed rear drums are seized, I'm afraid that I'm going to have to get brand new brake drums turned for sizing. The engine isn't a 79 apparently (H or I cast into the block), has a 80-85 distributor but what appears to be 79 ignition coils. I have leading on TDC but can't even get trailing to even show. I'll be posting for help on the Need Technical Help thread soon.

Slow and not so steady.
After running for a while the engine up and quit. So I went back to the Holley with a dlidfis. Now the car is idling and the backfires have diminished. My neighbors are happy.
Problem is that I cannot set the timing. I cannot see the timing marks at all.
Don't know what to do.

You're rotated the whole pulley and can't see any marks? Or you just can't see them with the timing light? Have you tried feeling for indents, rather than just looking for red and yellow marks?

I have a rotary addiction

There should be 2 indentations on the pulley. Remove the flywheel scatter shield behind the exhaust manifold. Line the flywheel up with the flat spot running even with the exhaust port side and you are at top dead center. You can now stab the dizzy and be within a few degrees of proper time. This is a T2 flywheel, but same technique.

I suspect that I may have a bad trailing pickup. I went with a dlidfis setup and it made a very big difference, even without the trailing working.
Anyone have insights into what it could be other than the pickups? Can I swap the pickups T-->L to test them or are they location specific?
