There was another thread floating around about this and the combo worked well. seeing it will be just for power, nothing can dump more fuel then a carb and the injectors will help the low end.

The reason carbs act like this is that they allow more atomization AT HIGH RATES OF AIR FLOW. EFI systems don't allow for atomization in the proper, more to the fact that they A. spray the fuel at the hot intake valve (not our case, dur!) causing it to vaporize instantly or B. spray at an atomization plate that forces the fuel to be picked up by the air speeding by.
This being said, the optimum setup would be the EFI system that we have currently with a single or pair of injectors in the intake pipe that come online at ~5500-6k rpm, thereby giving you the best of both worlds.

If you want instaboost....why not go with a vortech blower and stick with the Fuel Injection. They are pretty well priced i hear. Altho, with the carbeuration...thers a guy who comes by Rx7specialties....he has a camden blower on a 12a....atkins makes the kit. Im not sure...but they may make the kit for 13b. Check in on that. I think you can get it with or without carb...which will save you #...and its a draw thru setup...carb sits on supercharger body. I dont see why not stick with turbo II. As far as im concerned boost is boost. One just hits later...but when it hits *droooool*

My thoughts
Hey guys! NeilTII here! I ran my blowthrough setup for a while and produced great power and numbers.....but, the reliability wasn't there. I ended up blowing my motor a few weeks before I left for Japan. Now I am buying everything here that is best for my TII and mixing it with my Jay-Tech intake to produce one hell of a motor. I'm planning on running an injected setup from KGParts.com called ProJay. With a Japanese fuel managment system I should be pretty good. The Japanese have never seen a Jay-Tech manifold....at least the rotor heads I've talked to here.
As for the blow trough.......great for the strip but not for the street in my opinion.

Also.....I wouldn't go so far as to say that a carb is the easy way out! It took me around six months to tune my carb setup. EFI is easier in my opinion because it can adjust to the environment you are running in. I had to change the jets and mess with the mixture almost every time I went out. But....EFI is going to run stronger than carb because in technology you usually go forward and not back. That's why I've choosen to go with the 4 barrel injected throttle body setup. I learned the hard way but I'm glad it happened.

Agreed on the EFI arguement, allows better tuning, smoother, and so forth.
Anyway, most superchargers you'd burn up the rotors on by forcing compressed air back through the system from the turbocharger, coupled with the excessive heat this makes while being forced to spin, the coating wears out and you end up degrading the supercharger over time.
