Titanium isnt overly expensive if you supply the materials yourself. Dont do aluminum exhaust, it will crack guaranteed. Ticon industries makes great Ti mufflers and vibrant sells 1 meter tubes (3.2ft) sections in 3.5 for $175. The best way to do it is to buy all the materials and mock it up then bring to a competent welder that has Ti experience and is going to thoroughly prep the material and back purge the **** out of it. Im building my own dual 3.5” setup on my Rx7 soon.
I've seen aluminum downpipes eventually sag when used directly off a turbo, but they didn't crack. If someone has cracking issues that far back in the exhaust they screwed it up pretty bad.

Lol if aluminum works so well why did Vibrant discontinue their aluminum muffler series? They crack and cant handle the heat so it wasnt profitable with all the warranty claims and eventual lawsuits.
Cheap is all relative, quality 304 stainless is $35/ft which isnt that far off the price of titanium. We arent building old caddys that are 16ft long either so im gonna spend 3-400 more for titanium. If 3-400 is too expensive then your in the wrong hobby.

I already have half the titanium I need to do the exhaust how I want it. I need a few bends, another straight section, and mufflers.

You are getting raped on the 304 prices! 304 is considered budget stainless no matter how much you spend on it, for that money you can easily get 321 stainless.

$3-400 additional for the materials, plus whatever the labor is to weld it all together if you don't have the ability to do so. But sure, if $3-400 is too much for someone to spend on upgrading to titanium, then it doesn't mean they are in the wrong hobby; it means they simply make do with a regular ol' exhaust. There comes a point of diminishing returns in this hobby where the dollars spent no longer justify the gains made. For many people, a titanium exhaust is on the wrong side of that bell curve.

No doubt you don't have to spend a ton of money on parts to hit most goals. I like to because I sell parts when I want to change things up and I get more money back from quality parts than I would with budget parts. It helps in the long run. I paid for my turbo setup by selling off all my old parts on the last car. Selling the parts off this car paid for 3/4 of this build. Selling a few more parts to pay for a good chunk of this next stage. Etc.. Etc... All depends on your end goal and budget.
And yes... turbo > *
I'll never turbo another corvette. I'll get something else for that eventually.

If you want to lose some weight you could also try a lithium ion battery. You want one with some staying power so the Antigravity 40ah one is like 15 pounds our stock Z06 battery is 32 pounds so 17 pounds there. I do not know much about the lithium battery maybe somebody here has and they are too difficult to work with (I know they are expensive this one is $800) etc.

I used to run this one. A friend of mine had one and it popped on him. Saw another 2-3 people that happened to, so I decided to stay away from it. The anti gravity I got was only $100 more.

Bought some Diamond pistons. Lighter and will net a slightly lower compression than the Wisecos I have. Going to sell the Wiseco pistons. Compression should now be 13.9 with a .051" gasket or 14.3 with a .041" gasket. Should also be easier/cheaper to balance the whole assembly.
Other than that. No big updates.

Shortblock has been torn down. Crank is getting balanced. Diamond pistons averaged 50-60grams lighter than the Wisecos. Rods are in great shape. A lot of the bearings had some extreme wear. Bunch of particles in the bottom of the pan. Most likely pretty lucky that the piston broke or I'd have a huge mess to clean up when the bearings, eventually, took a dump. Block should be getting honed this week. Hopefully done next week or the following. Still waiting on my heads.
Taking this time to do some weight reduction and clean up the engine bay. Relocated the fuse box inside the car. Excited to have it back up and running.

Most likely. The previous tune was pretty bad as well. I ran a log before I tore it down and was getting an insane amount of knock. It was commanding like 40 degrees at over 60% throttle. I'm sure that didn't help.
