Sounds like your Cosmo n/a engine is probably the same thing then, I have two big injectors.



Well, time for some research then https://www.nopistons.com/forums/pub...IR#>/smile.png

yah, fyi our injected s3 rx7 is like your 13b na cosmo, 2x 680 injectors. its works well for a stockish car, but mine with an exhaust has the fuel maxxed out

Ok thanks for that.



There is a Cosmo here with bridgeport 13B NA 6 port that we put the early Gen2 (pre 88) turbo intake hardware and ran a Microtech fuel only computer. Never got on a dyno so i don't know the power.

It was nice and crisp, although the car is a bit heavy for NA. Your 7 would be a good 500 lbs lighter!

Never got on a dyno so I don't know the power, but it felt pretty good!
