Has anyone tried this setup? I've seen this on other turbo bolt on kits. Wouldn't it work for the SR?

While cheap, the word is that it doesnt feed all the cylinders evenly. you just need one overly lean cylinder to make you have a bad day.

Yeah, I heard it won't supply fuel evenly. I was thinking in the low boosted cars. I don't plan on upgrading my turbo or running really high boost. I was thinking in the terms of 14psi and under if the need is only for a little more fuel. I don't plan on tuning the crap out of the engine to squeeze every little ounce of power out of it til the point it's unrealible. I was just wondering if anyone with a sr had done this and what the results where.

If evenness is what you want, why not weld up bosses for 4 additional cheap SR injectors? 370+370 per cylinder, but i have no idea how you would control them.

I've seen this done on a 99 FM turbo kit for the miata I helped install. The injectors were linked to a box. It was connected with a vacuum line or map sensor. When it saw boost the injectors where turned on. The only problem was the 99 miata intake manifold was two pieces. We had to take apart the manifold and install a new upper half with the injector ports already machined into them. It was a pain in the ***.

the same reasons why you should not use wet NO2 systems. any deviation in airflow to the cyls will result in different fuel proportions in each. Also the risk of fuel puddling in the intake.
