Jim,
Have you looked at their website
(http://www.techtonicstuning.com/) and clicked on "Dyno Tests"???
There are all sorts of results in there but I can't remember if the
cylinder head comparison is one of them. I can remember reading it
and, yes, the 1800 head was the way to go. You can always drop them
a note and ask them if they've got a copy of it tucked away
electronically that they can send to you..........Jack
Does anyone have a copy of the Amazing Dyno Stories document that
Techtonics Tuning put out regarding the 16V Intake and Exhaust port
studies? I think this came out in the early 90's. They had a few
graphs that showed the air flow between the 1.8, 2.0, and TT ported
heads for the 16V. I also recall further on in the document, they
suggested that the 1.8 head over the 2.0 block was the way to go.
Thanks,
Jim
