When I get a moment, I will be switching from the V belt system back to the W belt, on the side note the W style Alt is failing just a reminder for myself and I do not have a replacement at this moment in time.

When complete I can finally time it correctly.

Well after all of that I am pulling the bartco motor and seeing if there is something I can do either with the other ca18 or bring the ca20 down to the machine shop to fix the cracks.

The bartco motor wont start even at the normal TDC, it needs to be set at +60, and even then I can't time it. (technically 1/4 off of TDC)

Well more comparing between motors, I have pulled the ca18e out and did a rotation test and the rods seem to have 2" less travel in the ca18et than the ca20e I should have taken pictures with the measurements. but I am not sure if the ca18 / ca20 rods are that different, crank,  and / or pistons I am a bit confused at this point but this is a mysterious ca18et motor from the start.

Back to going all out on the ca20e block I've put the head but installed the cam / cam gear for the ca20 on this ca18e head as they are the same heads all around. In theory this should be like a fully rebuilt system since it is in theory rebuilt.

CA20 block I thought I had blown up from the head gasket failure but that was a mistake on my part. 

2/3 of the motor has been assembled and installed adding in the accessories and should be able to fire it up either tonight or tomorrow night after work.

As for not being able to set the timing, is the only problem that the timing lines on the crank pulley and the arrow on the lower timing belt cover don't line up as they should when the engine in fact is on TDC? If so, try to get the bolts out of the crank pulley and rotate it. The crank pulley assembly on mk1 engine is not foolproof, it can be assembled wrong. Not sure about a mk2 engine, it might be the same...

the timing is different from the ca18et and ca20e to the ca20e ecu, so I swapped out the ca blocks and it is now running just fine.

On a new note, she is working good. I took a nice test drive and worked out great no issues, no hesitation just like she would before.

Here is a walk around video.

So I have did some investigating, and turns out my exhaust manifold gets almost 800F and my head is also pinged that high as the heat from the exhaust is also hitting the head.
This I believe what warped and damaged the previous head. I might proceed with a header wrap after tuning down the advancement as per suggested.

After that I am going to work on prepping some A/C install as I have a stock piled parts and going with propane as an r12 replacement.

I wonder how significantly the cylinder head temperature will change after you wrap the exhaust manifold. I think most of the heat on that side of the cylinder head must be from the exhaust gasses going through the head to the manifold.

Drove it out of an emergency this morning to acquire a replacement battery for my 350z.

My Maf fell off going to the gas station my tube is also in bad shape so I am going to research if I can just install a custom CAI instead of this long black oem.

I've seen people use the aftermarket pipes on them so you should be good...
