Thanks Emilio.
After being faster than the STL lap records for Sonoma and Mazda Raceway on the Toyo RRs, it's time to keep the development going towards the PTE or D championship I'm going for this year.
Starting the dyno re-class 1.8 non VVT build this week. Block is at the machinists to get hogged out slightly. Time to put the small block on the shelf until the big show. Hope some folks start signing up for Watkins and Buttonwillow, we need more completion in any PT class.

What cam gears are those?
Any other updates?[/QUOTE]
Those are the cam gears from Mazda Motorsports.
The 1.6 is getting a new intake cam and header. Try to boost the entire curve a little bit.
The 1.8 will start going together tomorrow. Rotating assembly is in just need to put the head on and accessories. Few tricks with that engine package doing the dyno reclass. Thank god for extra I/Os and direct motor control with my ecu! It will be fun, going to try and dyno Friday.
Ended up wiith 11:1 final c/r, had to take a little more off the head to get there.
83.5mm supertech 11:1s
manley H-beams
ACL bearings
boundary pump
JPM crank pulley
endyn CNC BP4W head
stock cams
square top
Raceland header
It is part of the JPM/BHJ race crank pulley. It's a electromotive sensor and a 58-2 wheel.

Depends on how the testing goes with the 1.8, the VVT that was in the car when I got it drove me around Thunderhill very fast. This should be a littler more oomph and lighter. The 1.6 is very fast and will be strong at the Glen.

I just finished on the dyno. It's a little soft from my dreams. Some big items that I feel can get gains, just having a hard time balancing work from play. Still hit the reclass numbers with out a problem. 141whp target with a big power band. Have a few test days planned before I go to Watkins Glen at Sonoma and Thunderhill.

Do you know where a good PTE build will fall next year with the proposed new classes? I'm not there yet, but trying to get things together to have a solid car one day.

The 1.6 can run from 150whp and up so between my two choices there isn't much difference besides power band below 5000rpm, weight, and or gearing. All to take in account to choose what ever engine program is better.

There was a clarification. Modifying trans tunnel to fit a chair, no points. Cutting the actual floor and frame rail out to lower seat, is 100lbs penalty.
Cutting the floor to lower chair in any other car is illegal in PT, and has been already. This is just so that spec miatas that do the floor drop mod can still participate in PT but at a disadvantage, since nobody else is allowed to do it.
