The 5S block machining has now been completed.
The head was serviced too, and that went smoothly with no issues found.
This means that Advance will start reassembling everything very soon!

The re-assembly of the engine is almost complete. Here are some pics.

Hux Racing billet steel main caps:


98+ 5S-FE block with pistons installed:


The Gen 2 3S-GTE head and cams are staying the same as before, but the head was just serviced.
The head is already ported, it already has shimless buckets and upgraded valve springs/retainers, and the cams are the same as before (CamTech 265in/271ex cams):




Hux Racing head stud support washers/hats (these require some machining of the head):



Not much left to do now:




The exhaust system looks better than ever after a cosmetic clean up:

Rob. I like it. I'm sure it would already have been taken care of but I have seen it forgotten when swapping from
3S to 5S block. Tap a thread in the oil feed for the 5S  balance shafts and seal in a grub screw.

You're not the first person to mention that, but it's already been done :-) I think it was done in the photos too, but it's just hard to see.

?? Mine doesn't have balance shafts.
I thought it was only the early model blocks that have them.

My 98+ 5SFE had balance shafts which needed to be removed.

I'm pretty sure the balance shaft thing is to do with whether it came from a Celica or a Camry, not what year it is

Jaemus is spot on. Origin of the block dictates the balance shafts.

My 5SGTE has the Camry block with a Celica crankshaft.

This thread has more detail, see the 1st post section 5SFE Parts / Block Prep C:
https://www.mr2oc.com/61-3sgte-turbo/395274-how-build-5sgte.html

I have attached the associated picture which has been removed from that thread, and was sent to my engine builder for reference, so Rob will be fine.

Here's the custom twin fuel pump setup in the stock fuel tank. 
It's a pair of F90000267 Walbro E85 fuel pumps, on a custom hanger, with a custom enlarged opening on top of the stock fuel tank. There's a -6 return line, and twin -6 fuel feed lines merging into the existing single -8 line that goes to the fuel rail via a Speedflow fuel filter. The entire fuel system uses braided Teflon fuel lines. 
Yes these pumps combined will provide way more fuel flow than I need without a bigger turbo, but I'm not comfortable with how close I am to the limit of one of these pumps, and these are the only ones I trust on E85.

Wow that's nice and tidy.
Did you help design it all?
