Hello all. As you may have read on another thread, I recently acquired one of Mark Burton's twin turbo kits for the Buick 350 from a board member. This has been a dream of mine since getting my Skylark and joining this board. I started this thread to document the installation and mockup of the kit in general before I pull the 350 for a "refresh", and also so I can ask questions as I go! The first problem I encountered yesterday was steering shaft interference with the driver's side turbo manifold. As I tightened the manifold to the head the clearance seemed to get worse with the manifold getting squished, so I backed off to avoid breaking something and warping the manifold. See pics: Anyone have any tips? I don't mind putting some dents in the manifold with a ball peen, but it's not my first choice. Am I doing something wrong? Can I run a smaller diameter steering shaft or grind my current shaft down a bit? It does get way thicker right where I'm have issues. I also read that worn motor mounts can cause this? ---------------- General notes/plans: -Not planning on running an intercooler yet, but probably the first thing I will add after it's all together -My kit came with mild steel 2.5" down pipes made for the 70 - 72 Skylark chassis (not sure who made them, maybe Sean?). -My kit did not come with any cold side piping, I plan on fabbing it myself from mild steel -My kit did not come with a carb hat. Either going to go with Spectre hat or EV hat. -My kit did not come with wastegates, so I bought a pair of used Tial F38 wastegates locally (great price) -Already have meth/water injection kit with progressive controller (got it 50% off during Sema sale!) -Planning on running TA SP3 (have dual plane now) -Hoping to go Holley Super Sniper EFI instead of blow through carb -Still deciding between Tanks Inc EFI tank or RobbMC powersurge -Kit will be run on a stock SP code 350 that I will be "refreshing", if it blows up at least I tried . . .
