Joey the 750's should be fine with the emanage. I however have been told by countless people to go with the Injector Dynamic's 725's. Ptuning is opening an account so they can get me them. I hear they are great, I would highly consider them. I should be running them in the next few weeks.

Did you notice how the Greddy exhaust manifold runner inlets are discernibly smaller than the OEM exhaust gasket?
For some reason I notice that the OEM exhaust gasket tend to be a bit bigger than the exhaust outlets and manifold. I am not an engineer but I would guess that the engineers want to reduce the direct heat to the gasket...it's just a guess anyhow....love to hear some feedback from an engineer.
This is awesome! I love how there are more capable turbo upgrades for the Greddy kit. So 14psi on stock HG? Is that safe? What psi can you run with an aftermarket HG? E85 should be able to accommodate. I guess the big question is what is the highest boost one can run on stock engine internals?

.. but im sure 14 psi would be ok with proper tune... I may have tried this but I have the base greddy turbo still and it doesn't make any more power after 12 psi...

Its definitely capable of more power. With the greddy turbo in the high rpms it felt like I was pushing superheated air just to get a few more ponies. This thing just takes off and doesnt stop till redline. You have to watch the revs a lot closer than the greddy turbo, this thing goes up quickly. Im above 70% efficiency with this turbo right up to 9krpms. If you look at the compressor map the turbo has lots more to give, apart from the intake piping, I think the Greddy IC and piping is fine for more power, might pay to change the DP to slightly bigger 3" . For now Im loving it, drives like stock till 4000rpms, then really takes off and doesnt stop.
Oh by the way I already have a 3" single , HFC and a ACT clutch kit that was put on the greddy kit when I first started.
I havent brought the car up in the twisties yet, but will do on the weekend. I think this powerband is going to be a lot more predictable than the greddy.

Wow 25psi? Do you have any build threads you can reference?
