I can't speak for the Steedspeed manifold, but in general the stress on the exhaust studs is high on either a top mount or bottom mount turbo and any type should be supported with a strong brace. The factory studs are strong but the Steed manifold uses fewer studs on the top than the factory. I wouldn't run any manifold setup without some brace to ease the load on the top studs. The engineers at Toyota saw it fit to have the turbo/manifold assembly braced, probably for many reasons. The Steed manifold is one of the stronger ones out there, partially due to the nice and beefy 5/8" flange and thick wall construction.

I have the manifold.  Absolutely no issues ripping out studs.
Most of the weight is vertical on the studs... Two cases I'd worry about studs:
1) You have a hard/solid exhaust system w/o a flex pipe - and you're not using the factory exhaust mount spot on the engine/transmission.

2) You buy a cheap manifold that warps.  (IE, not SteedSpeed)


Leen has really gone out of his way to work any possible bug out of this manifold.  If you're wanting something you can bolt/weld a bracket to, just ask him - he's really easy to work with.

I have the steed speed and no problems 'cept the one I created.   Header flange gasket started leaking on a road trip.  Likely 'cause I reused lock nuts.  DOH!  What header gasket are people using with the steed speed.  Looks like I need a new one.....

I honestly don't know... The 22RE or 22RTE one should work.

Adapter on the factory oil feed (block tap) to an AN style braded line, to a filter, to another line to the turbo.
