Sorry I can't remember where I got that carbon fiber coupler, I have been at this project for so long I loose track of some things.

Ok it has been too long since my last post. Long story short I got sand in my intake manifold from sand blasting which got into my ring landings and seized my rings to the pistons. I did a full rebuild with new je pistons and stronger wrist pins. I didn't have the energy to build and post but now that it's done I decided to update my post.

I updated the Pcv system also by welding a -10 AN fitting to the valve cover then welded another -10AN bung to the bottom of the catch can and routed that line back into the oil pan.

Lastly I directed some attention to the interior. Got my Recaro seats upholstered and sliding rails welded up, while I was in there I decided to address the door cards and used the extra material from the seats to redo the door cards.

Here are a few shots of the interior after getting everything installed. Also forgot to mention I replaced the rack and pinion with a brand new unit. The old one was rebuilt by the previous owner but it was leaking. I also installed an adjustable cam gear and phenolic spacer from 034 Motorsports. The valve cover and intake manifold were sand blasted and powder coated, hense the damaged pistons. I also ditched the AAN ecu and bought the plug and play VEMS unit from Marc. I had to weld a bigger bung on the flywheel for the VEMS.

The entire engine was hot tanked, head, I/M, fuel rail etc. just to be absolutely sure that all contamination was removed! I also pulled apart and thoroughly cleaned anything that had to do with air or oil. I also had the crank, harmonic balancer and flywheel balanced at the machine shop. So all said and done about 4k in a full rebuild and associated parts, absolutely rediculous how much money and time spent, I have to believe that it's worth it. To be honest I have learned so much so this is, in a way tuition, albeit very expensive.

Like I said its been a while so I keep remembering things that I have done. I was about to put on a new timing belt after the rebuild and noticed a crack in the super torque cog from 034. Less than 1500 miles on this part I used the correct tool for removal and installation and I torqued it to correct specifications but it still cracked.

I don't know if its visible but you can see a crack around the key. I since updated this with a machined piece from EFI express for peace of mind. You have to pay close attention when you build a motor to find little things like this that could possibly result in a full rebuild. BTDT don't want to go down that yellow brick road again!

I just got them done over the past two days so I hadn't even started on them when you stopped by.

Omg those seats.

Crazy about the rebuild! Sucks, but you did it right. Fwiw I had my whole engine hot tanked and then I cleaned it afterwards and still a small piece of steel or aluminum got into my turbo and killed the bearings. I haven't yet, buy I SHOULD be running a little filter on the oil inlet. I think forced performance has and sells one and Hank recommended it.

What are those seats worth?

Ok good to know about the oil filter I will definitely be getting one of those. I don't want anything else to keep this motor from running. The seats were a little over 2k when all was said and done

Sigh. Hate to see knock in an engine, especially School of Hard Knocks. Hope you graduated...

At any rate, things are looking up and the project is moving along nicely.

I agree, I spent even more time rebuilding the engine this time than last. I knew my way around much more so I could pay attention to smaller details this time which, in theory, should prove to be a much better build. I am very confident that this time it will be just a matter of playing with the VEMS to get it dialed in.

Cheers
