Are you guys sure they will bolt right up to my ej22T? I have searched and not found to much on the sti heads/ej22T block.

Thanks

Dustin

I had heard something about using the EJ257 heads on the EJ22T block on NASIOC IIRC and the head bolts need lengthened or something but besides that they worked. I don't actually know personally though so....

do it. it will be a great set up. but of course you will need one of my ecu's if you want to utilize the vvt function. if you don't utilize the function there are better setups than that.

Have you tried this Kelley? Is there any problems with the coolant passeges lining up with our blocks, like the 2.5 n/a heads have?

Kelly, what is your ecu? the vvt for the sti's work on their own at a certain rpm and dont require the ecu to turn them on. It will not be as much of a gain as if i would have the sti ecu, but it will still be better then nothing. I am running a TEC 3 stand alone ecu, so i am not sure how your ecu would work with it. As far as I know no aftermarket ecu will be able to controll vvt.

Thanks for the input

Some ECUs can control the VTEC switch, but I don't know about Subaru's system. How does it work - does an increase in oil pressure drive it and how variable is it? Is it a simple can lobe switch like Honda or a more variable system like some other manufacturers use?

I am not a complete expert on the vvt. I will try to find the nabisco link the explains it.

but as far as i know, no stand alone ecu will be able to controll vvt.

is this for real sti heads will fit on a ej22t motor come on, does any one now for sure 150% what would i need intake manifold and heads.

you will have to address the thumble generator issue too..
