so any idea what psi would be 100% ?
Could you elaborate a little more on that? They're both 2.0 liter 4 bangers. The S14 turbo is pretty similar in size to the CT26, they both rev to about 7k, both stock turbos are good for nothing past 1 bar of boost. I don't see what a little headflow has to do with it here, unless the SR sucks at life so bad and doesn't flow near as much air or come close to making the same power at the same boost as the 3S. I know they're not that bad of an engine to throw down around 300 to the wheels on a stock S14 turbo with all the bolt ons and a tuned PFC.

the stock turbo won't hold 14psi solid, and the injector duty cycle is between 80 and 90 at that pressure.
Turbo maxed before injectors right?
Ever think of upgrading to a CT20B or CT27?
Rather then getting a different turbo, send it off to get the turbine housing ported. Can install a larger compressor as long as the turbine is ported too. For less than a 20b or 27.

That's the trick with the CT26 many people miss.
i've got a 50 trim sitting. just wanted to do this first. i figured you guys would enjoy the info.
and yes turbo maxed out before the injectors
200 - really if they were so close to the same thing then why didn't they use the same motor. yes number wise they are close but other than that, all the electronics are different. the head flow/cams/valvetrain/piston design/manifolds/drivetrain (which does make a difference)/oiling system different. a better comparison for my motor (which i'll assume we are talking about) would be a s13 motor not a s14. like comparing a 165 to a 185. if you are revving a stock 165 to 7K you are laying waste to a good motor. there is no power gain past 6400 on the stock cams in a 165. so that's different. and 300whp with bolt ons? really that doesn't matter. if you think about it lets throw in every other 2 liter turbo motor. like a 4g63. sure it's the same. i can run a mabye 14 on a stock 165 with a boost controller. or low 13's with a stock dsm and a boost controller. apples and oranges bro. i don't mean to sound rude but it's like trying to return a TV you bought at walmart to kmart. same in ways but nowhere close to the same under the skin.

I figured there were enough similarities there to warrant it a feasible comparison, but I was under the mistaken assumption that you had a 185. :doh:
Mafix, you're fuel system is set up exactly like mine but for some reason, while I'm not blowing any smoke at all, I am burning a lot of gas. I know I have a 185 but maybe you could tell me what your AVC-R says on idle at normal oper. temp. for injector duty cycle.
Mine starts at like 96.5% and as the throttle opens it falls to 86% and then varies between those two readings - is that duty on idle normal?
