6" rods, custom pistons with 3.7" bore; titanium valves 1.8"/1.5" and a higher revving cam with ~.550" lift






Take some extra axles to the track because you'll go through them much faster now with that engine combo. Ask me how I know! And I don't know what clutch disk you have but a sintered iron disk would be perfect if you want to soften the punch on take off and be able to do it over and over. For your kind of racing I'd use a solid hub iron sintered clutch. You can slip it, dump it, etc and it will take the abuse. That way you don't look so predictable to your competitors. Can't wait to hear it roar!

There are individual Volkswagon gaskets I can use. There's also a larger gasket that comes with 3.4L Summit Headers that fit well.

I used the VW exhaust gaskets as well. (not sure if they're available in Stainless Steel)
But I got these copper ones with the 1-5/8" hole that people were recommending. (4 in a package)

It's only once I got them that I noticed the stock exhaust gasket and heads only have a 1-1/2" outlet anyway.
1-1/2" rings also available - could have also used those. All installed - no leaks. YAY!!

Got holes closed up and had the Trueleo headers ceramic-coated. Also engine has been delivered to the shop for installation.

Wow! I just noticed this. Your passenger side driveshaft has some sort of support bracket with bearing... rather than I guess what the other Fieros have, which is an absurdly long driveshaft which can probably get somewhat easily unbalanced. This is pretty cool... was this custom, or is it specific to the transmission you're using?
