Default Possible for a 1.6 to be competitive in TTE with manly driving?

Quick explanation of why I'm considering this, I have a spare Long nose 1.6 I was going to put in the car to get through next year anyway. My thought being, while it's out deck the head to get the compression up and throw some cams in, which would be relatively cheap.

Possible for a 1.6 with ~11.25:1 comp and bigger cams with a decent I/H/E could put down 125whp and have a min comp weight 150lbs lower than a 1.8 NA? Put good pads/fluid and duct the 1.6 brakes?

Points:

Big Grip kit +7
MS +3
I/H/E +6
LSD +3
205 NT-01 +6 (or maybe Toyo RRs at +8 to get to 39 points)
Cams +6
Head deck (with less than 2.0 comp bump) +6

Shoot, I'd say 125HP is easy peasy. 1.6 SMs are hitting almost 120 to the wheels with stock head / cam / compression (with some super secret massaging). FP miatas are 10:1, stock head & intake, .390 lift cams and every bit of 155HP to the wheels.

Base 1.6s are classed TTF**, not TTF. You only have 25 points to play with, not 39.

Even if you dyno class, which would be the only way to make that motor package fit into TTE, you'll still be down 5+whp on a competitive 1.8 car and a lot more torque (like 15-20ft.lbs). I doubt it would make for a competitive package.

Thanks, I figured I was misunderstanding the points stuff.

If you already had that engine setup, you could probably make it semi-competitive... enough to go out and have fun. I definitely wouldn't put any money into a 1.6 for TT purposes, though. You'd want it dyno reclassed for sure, and you'd get the exact same pwr/wt ratio as a 1.8 car. Like sav said, the torque difference is huge. I sometimes wish I'd started with a honda just for the junkyard 2.2L+ options.

The top TTE in the Texas Region is a 1.6.
Dyno reclass, stripped out interior, front air dam, R6s.

Pretty sure Savington might know.

FWIW, this is my plan if I can ever find a VVT or a BP4W motor.

Competitive nationally or regionally?

Nationally, no, see above answers

Regionally, maybe, depends on your region and who runs in it.

As was mentioned, you would want a dyno re-class regardless
