I dont want to sound like a smart arse but my experience all comes from me. I barely read magazines to tell the truth i spend most of my time on www.gt4oc.com
If i am wrong about the Gen II vs Gen III head then i guess i am wrong its just not what i have expeienced.
My 3sgte was built with massive hp in mind too. I built one engine myself and one engine i got built with all forged internals. that motor cost me 15,000 including the turbo.
For my HP aim the 205 head would be beter.
There are things i know that maybe other people do not.
For example it is true that the stock 185 fuel system does not handle more than 12psi of boost/fuel delivery very well, although it can, it is not recomended at all. Whislt the st205 head with its fuel rail is capable of 24-28psi. Its a shame the 205 fuel rail does not fit onto the 185.
All these little things are so important to know when tuning cars. They are often overlooked.
I stand to be corected about the 205 head not being as good for high hp.
Also does anyone have dyno sheets to proove 500+ hp celicas without a 2.2 stroker?
