I don't think CTR pistons are gonna help you beat the cobra. Has the car been tuned? If so on what and what are your numbers? If I were you I would upgrade your header to an SMSP or Hytech. It is worth the money. My car has a 98spec jdm itr swap bone stock internals with an smsp header j's intake and 63mm exhaust. I put down 198whp on a mustang dyno and I know for a fact my car can pull on a 98cobra.
Do you know what was done to the cobra? Are you running an itr tranny? Did you race from a roll or dig?

tuned on hondata s100 by tempest racing. i put down 190 with stock 98 itr block, b16 head with itr cams and b16 trans. the cobra was my friends and he's just got an I/H/E. we went from a 20 mph roll and i stayed in 1st. i pulled him through the first 3 gears but when he hit 3rd he took off

The biggest difference you would see is fully balanced bottom end. It makes a huge difference in acceleration+Smother and less stress on engine makes them last longer+you can lift the limiter. Light weight pistons all weighed and matched, knife edge shot peened balanced crank and flywheel and it'll be a racer! + you'll be surprised of the cost it wont brake the bank Big gain for your $$.
1.Reduced need for a heavy flywheel or similar devices.
2.Reduced wear.
3.The opportunity to reduce the size and weight of components (other than the obvious one of the flywheel) as a result of reduced stress and wear.
4.Reduced vibration transmitted to the surroundings of the engine.
5.The opportunity to extract more power from a given engine by: Higher maximum operating speeds made possible by reduced stress.
All good stuff

Um... ok go with a RMF header but either way you need a good flowing header. Im not gonna say RMF is a better header because I have never used it. But I know for a fact SMSP's work.

Na. It turns a normal car into a super bike engine! 14.000 rpm is attainable!
Lighter the better!

next time your in the market for one try them out man. they are amazing. the knock offs from ebay are literally exact replicas. (the only reason i know that is because vteckidd from hondatech is the one who sells them. the designs and bends and welds alot of them.) they really are well worth the 450$ i thinks its a best bang/buck type things. but they definatly work haha

JDM 98 ITR pistons would bump the compresson ration up to 11.1 from the stock 10.6. BUT the CTR pistons would bump it up to 11.6

one point of compression wont solve a 3 car-length beat down
a tune, better header, and a thinner head gasket will take care of that pesky cobra
