I hate when life gets in the way of bench racing!

The lack of potential I was referring to was the lack of the 4AGE to get predicted power gains. There are more than one 100% motor builds (less the new ECU rule) that aren't getting 110hp to wheels. THIS is why the car isn't as competitive as it looks on paper. THIS is why it doesn't have the same potential.[/b]
Note: Open ECU's are not new...can a MoTec fit in the stock box?

Why doesn't it respond to the same tweeks a 2.0L VW or Honda Motor does? We can easily get into a engineering discussion on that. First off it is a 1.6L (20% smaller) and produces the same stock hp as some ITB Hondas/VWs by reving up very high and a fairly optimal head/header design. [/b]
CRX 108 stock hp - 1.6L. Miata 116 stock hp - 1.6L.

There are engine builders that have found match porting actually hurt hp, and nobody has designed a header that had gains of more than a 2-3hp. This can be argued to death as I am not a Toyota engine development engineer. [/b]
Sounds EXACTLY like the 1.6l Miata (except for the port matching piece - unknown on that - Miata's have very small intake and exhaust ports) in that all the bolt ons do little to enhance power. The real power is found in the A/F tuning. Can someone post a dyno sheet with A/F ratios for one of these Toyotas?

However, as Kirk points out - the RWD "adder" has some engineering shortcomings. While an ITS FWD is certainly going to have problems getting the power down, at ITB power levels it is a totally different story. FWIW, I run an OPEN diff and still can't spin a wheel on the track.

There is no RWD adder. Only a FWD subtractor. Mid-engine layout in ITB is VERY unique and could be considered an advantage - especially under braking.
