Timing Belt Snapped

[TODA AU]

***EDIT***

OK got to see the car and drive it... feels exactly the same before it shat itself but it is now 10wkw less at peak and less everywhere and the AFRs are uniformly rich across the board... the entire AFR richened up about 3:1 across the board.

the only 3 things that changed between first and last rebuild are:
- CROME chip
- 65mm intake manifold
- 68/65mm TB


ideas? i would have thought the addition of IM/TB would have made me leaner....

Assuming she's been strapped together spot on,
Your problem more than likley stems from how rich it is running.
When you say 3:1 richer, is that .3 of 1 point A/F
Or 3 pionts.
ie: 13.0:1 down to 12.7:1 (this is ok - the problem is not the fuel so much)
Or 13.0:1 down to 10.0:1 (This would be the root of all evil)

In either case, you'll need to get the chip tuned to your car rather than a generic burnt chip.
With the larger throttle & manifold, without tuning for then, generally a B16A will loose power by simply addind these parts.
Eg: Stock B16A + Type R intake manifold + Type R throttle = -4hp @ wheels without tuning.
NB: The ECU runs MAP & is a pressure system, if you fit a larger throttle & shorter, thicker runner intake, the actual pressure in the intake will be slightly higher when the manifild vacuum colapses @ WOT.
This will result in more fuel being added unless it's tuned to suit the new manifold.
Airspeed plays a part too.
