I'd be switching up to a T3 turbo at this point.

why water\meth at 340? I wouldn't use water\meth until you are knock limited.
You have a built engine?

I'll gladly give up any top-end gains for a mid-range like that. I still want moar better down low...I'd downgrade it further if I could, but alas, this is about as small as it gets on a T3 flange.

I've seen that dyno before but iirc you had changes between the turbos, it maybe same pressure but I'm guesing actual airflow isn't the same.

yeah, the compressor wheel is significantly smaller, so the torque curve has moved to the left. This compressor wheel outputs more like a 2554 (25 lb/min) vs a 2560 (35 lb/min).








Keep in mind the dynos were different and the red line has correction, but you can clearly see the chinacharger is better sized for my 1.6L motor.

I'm working on getting my parts together. It just seems like a lot of people are having problems breaking 300. But now knowing what I know, would a 2876 be a better option than the 2871?

Than if you want to hit 340 find a turbo that will be in its efficiency zone at that power output.

I don't think people have problems breaking 300, it's just that most people choose not to go that high.

What is your description of "too much for a 1.6 on the street?" 2/10's of a liter make no difference.

Instead of bouncing around from turbo to turbo you hopefully understand that turbo size/selection should be made on what your final goal's are. I would/will and have chosen Garrett over other turbo's simply because they are a proven product. Yes sometime's I got pulled by a car length or two simply because I did not want to abuse my clutch or half-shaft's in my T66 MR2T but I quickly made up those lost length's and walked away.

Well that was before I became a police officer but my point is just choose what you want to achieve with the car and save yourself alot of money and hassle in the long term. Also imho any highly boosted engine should have an EMS that you can program boost level's via the gear or rpm for maximum traction.

Actually 2/10's of a litre does make a difference.

I made 300whp at 14psi on a 2871. I think that turbo will do 400whp.
