But wouldn't it be nice? Ram those RPMs up to 7,200 RPM and see how much power can be obtain. I'm really anxious to know the potential of these Heads, and yes it would be awsome for ZPI chime in here a little.

Dont know how many of you are on the ZPI forums, but this was stated:

Hey if ZPI will work with me on price i'll get a stage 2 head and dyno it for us heh heh, they can have my stock head, but i might be able to utilize it a little more than others since the local dealership here forgot to swap out my supercharger injectors back to the stock ones now i'm probably running pig rich... yup gotta love dealerships...

So its $2200 before the core charge? meaning that it comes out to $1500?
If thats the case I will get one in about 6 weeks.
Once I get this I'll shoot for larger injectors, and possibly forged pistons/rods.
but first I have to know how streetable it is, as this is my daily driver.

Is the ZPi head a ported stock toyota casting? Is it handported or CNCed? Does the head drop the compression due to larger combustion chambers? Do you have any pics of the ports and combustion chambers?
I am doing a tC buildup and we will do an all out all motor build before we turbo the car, and if you can prove the head is worth it we will be purchasing it and will supply dyno numbers.

well it said your supposed to get an emanage or piggy back unit of some sort with this and if i know my engine theory well enough (please correct me if I'm wrong) The engine management should correct with amount of fuel with the extra incoming air to keep the rations in line. Just what I'm thinking, I may be TOTALLY off...
