Why the TBI header is worth EVERY penny!

[Wizard]

This is not just for TBI. This is exact same manifold for carbed 2.2 also.

[it's all dodge]

but would it touch firewall if you had a T2 in there? Has anybody actually dyno'd one vs. a ported exhaust? getting the manifold no biggie, but who makes oil line not to void warranty of new/rebuilt turbo? and it's spendy to get a custom made downpipe mandrell bent

[Ondonti]

Any vendor voiding your warranty for things like that is full of crap.
They like to pretend that you need a special oil line but they are just making more $ off you.

...i changed way too much on my setup to feel the back to back difference... but its making alot more power, espically in the mid and top end.

a t-2 turbo i would imagine, should not be as close to the fire wall...

just remember, there was a back to back test with CFM and the tbi manifold, unported outflowes even TU's header. that should tell you somthing there!

proof is here: T.U header vs Ported Manifold

a buddy with a welder and a case a beer can do wonders for a custom downpipe!

^^Just read that thread again.
"I wouldn't let you port my toilet for more flow because all your bullshit would plug it up."

That was a funny comment.

What are you running for a swingvalve?

[Jay]

he won it from me on ebay, its a 88' tbi shadow manifold

[LynX853]

no swingvalve on a holset..

I'm not dissagreeing with anything you guys are saying, but a stock ported exhaust mani will easily support 450+WHP.
