Hey All,
Has anyone flowed both of these and compared. Is there much difference. Someone said to run the std EA/ED manifold in my ED turbo setup instead of chasing a BA turbo bottom broadband and Nizpro top which I can get for $850. Should I save the $850 or will it give me heaps more power/torque. TO4B with 5 psi (for starters).

It all comes down to $$$ vs kW's. What are your power expectations and how much $$$ are you prepared to spend to get there. Personally I'd be prepared to stick with the ED log manifold and see what it can do. But if you were chasing say 350-400rwkW+ then you may as well chuck the Nizpro manifold on from the get go. The factory Ford Log manifolds are heavily underated and you'd be quite surprised with what they are capable of.

cheers mate, just 200 rwkw off the 5 psi for starters for the std engine with 80,000km on the clock. just want an old ed turbo to keep up with a fg turbo/xr8 and ss/r8. jut like to surprise people not win bragging rights. was told to maybe go up to 10 psi max with a good tuner but if i do more i will buy a ba/bf turbo instead.

you will see good enough results with the standard manifold and 10 psi to chase hsv's and fg turbo's
the better manifold is for people chasing alot more power than what your after
your engine will handle 10 psi pretty well provided the tune is done right

cheers - the nispro kit was put on a std territory and blew it up running 12 psi so bits and pieces have been poppin up for sale - obviously his tune was not done right
