Default This setup may be crazy but will this work?!?

Stock turbo, tranny, block, etc.
Turboback exhaust no cats
Uppipe
Alcohol Injection
Dual stage manual boost controller (for alcohol injecting)
Link Knock Sensor (use to tune maximum alcohol injection and boost)

Good for 250-275whp?

I am not currently running WI/AI (so others will far more experience than I may disagree), but I would think you would get a lot more flexibility out of WI with engine management. Flexibility such as: low boost failover if you get a plugged line, pump failure, etc. (assuming you were running something like an Aquamist 2d WI setup).

You would also get much more power by being able to advance timing, etc.

I would think that the shortcomings of boost controllers with pump gas would only be amplified by moving to higher PSI with WI/AI.

Also, while the Knock Sensor is useful in tuning, it's more of a safety feature, and isn't a substitute for a wideband O2 or EGT gauge in tuning, I would think. As I said, I am not that experienced in this area, but I would think you would have a much more solid setup (safer, more power), if you spent the $650 on EcuTek (or Utec, Xcede, etc.) and a few hundred dollars on dyno tuning by a tuner with WI/AI experience.

You are going to need more mods then that for that power. You will need at least some kind of EM.

You need more then a knock sensor to tune.

It will still be slow with those mods.

You throw some alcohol injection in that with some EM, and you will have one seriously fast spooling turbo. It would sure be fun at the local autocross.
