Thank you John. I was debating on 2.25 or 2.5, but the 2.5 was a perfect fit into the T6 flange so I went that route. I will be keeping it a true twin scroll like it is. If she sees too much lag I will re-fab the piping in 2.25. Do you think twin 44's will be enough to control this turbo?
I see a lot of people use flex joints and some do not. If the engine and turbo are both mounted solid, do you see any reason to use a flex joint?

This will be a fun street/strip car.
I don't think the dual 340's will allow you to max out the turbo on e85. Maybe a blend of e85/pump fuel. We encountered this with a GTS76 and billet wheel (1200hp rating). Needed a KB Boost-A-Pump to max it out.
Walbro makes an e85 friendly 450lph pump now also....

Got the exhaust piping under the car now. Had to make some pie cuts to do it, but it has good clearance. Stared fabbing the 5" to dual 3" merge. Used some pieces of 3" scrap pipe to help form the transition. Ordered up a pair of 45 degree elbows to use for the final product. Thy will angle towards the center of the car and tie into the Pypes Chevelle style exhaust system with a pair of Race Flo mufflers and exit in the stock location. Should be super quiet.

I also ran into an issue with the Flaming River Pinto rack I bought. I assumed they used the stock size .625 thread on their inner tie rods, come to find out they build them with 1/2" 20 threads. The Pinto tie rods were the perfect length too. They don't make a stock tie rod in the dimensions that I need now, so I had to buy the Flaming River ones and hope they are short enough. As soon as I get them and get the rack hanging is place I will see where it needs to go for good bumpsteer angles and fab the mounts, then get the pieces I need to re-connect the steering shaft!

People talk about flex joints and cracking pipes.... Truth is you're probably not going to put 100k mi on the setup and a lot of guys run no crossover and never have cracking issues. I have a flex bellow on my bank that's furthest from the turbo, too many bends to put one close to the turbo, in the end after changing heads, trans and trans cross member... It moved my placement around a little bit and that flex bellow makes it a lot easier to get the v-band lined up (like a ratchet strap between the two headers and a crow bar between the A-arm and header last time). If you do go with flex bellows get them for a turbo application, reguale flex sections will come apart.

Both of my friends mounted theirs on the passenger side facing front to back. One with an LS 71 Camaro and the other with late model hemi in a 71 Dart. My car already had the front bars welded in for the big block I was planning to run, so it was in the way, plus I am keeping my battery in the stock location. I also liked the long routing for easy filter fitment and a long gradual transition for the 5" exhaust. I figured the longer I can keep the exhaust 5", the less back pressure I will have when it transitions to the dual 3".
