Strut bracing ideas for turbo 3rd gen

Not TECHNICLY a power adder thread, but it only applies to turbo cars so i thought id post here in case you dont see the one in the chasis forum.

Have any of you guys comeup with some sort of strut bracing design that works around your turbo(s)?

Heres a shot of my engine bay.



Obviously I can't just run a STB across the top. What otherways could I brace them?

This was one way I thought I could add some stregth to them. Worth it? Waste of time? Should I crawl back into my box?

The factory did something like that but instead bracing the corners and then the strut tower diagonally downward to the frame rail…

get a FIRST injetions TPI manifold with a side mount tb and run the intake pipe under the brace. (that is assuming the STB fits with the manifold).

not really the economical choice, but it would probably work without anything crazy or custom.

Do you have any pics or details on this setup. What/who is "the factory"?

GM, they're just maybe 5/16" rod from the strut tower to the cowl and from the strut tower down to the rail… I’m not sure which cars came with them since neither my TA or formula had them but a friend’s Formula did…

Hello there Luke and everyone else,

I am currently doing this (combination of the yellow lines in the turbo Camaro and the GTA)

Wow! Didn't even think or going that direction. Does your design involve going through the firewall and welding it all up under the dash? or ontop of everything and in the engine bay? Looks like ill race you to see who get the strut brace section done first.

And on a more personal note, I just wanted to thank you dude. Everytime i step on the load pedal and have to wrestle the car into a straight line, I think of you.

No, thank you for your purchase!!, but anyways it feels really good that you think of us in that kind of situation.

Currently the car has the custom made subframe connectors installed, now the connectors from the top of the front shock mounts has to be fab. After that the front end has to be attached since is just sitting on top of the car right now. The subframe connectors do not pass thru the firewall, I'll post some pics for you.
