I know there probably isn’t much i can possibly do to my car but all i really want is to try and squeeze a little more juice from my engine
first off my engine is a 3.1 L V6 out of a 94 cutlass cruiser if there is any sort of modification i can do to get more overall performance like injectors or anything a point in the right direction would be helpful in any way

 

You are hampered by the lack of support for the platform and the fact that it's still OBD I. In short there is nothing "simple" that will really wake it up very much, if at all.

 

The 2.8, 3.1, and 3.4 are all Chevy 60 degree V6 motors, originally introduced in the 1980 FWD X-body cars. They do have a following, but there is no easy or inexpensive upgrade. They can be modified, but it will require both hardware and PROM changes. The most effective upgrade in terms of bang for the buck is to swap the 3.1 for a Series III version of the 3800SC supercharged motor. This is the 90 degree Buick V6 and the Series III versions came with the same bellhousing bolt pattern as was used on your 3.1. Obviously this is not an easy or cheap swap, but it has been done.

 

i would look at s10 or chevy camaro sites. they had those engines.

also look at frero sites too

 

The reality is that there is precious little you can do to the car to increase HP without getting into reprogramming the PROM. For example, the injectors are already sized for the correct A/F ratio now. Changing the injectors simply makes the car run richer, which does not increase performance, it only wastes gas. Eventually the O2 sensor will get the ECU to dial back on injector duty cycle, so you'll be right back where you started. You need to improve airflow through the motor, which means reducing exhaust and intake restriction. Once you do that, THEN you can play with mixture ratio and timing curves. Unfortunately, a 94 is probably the oddball OBD 1.5 system, which is pretty much unsupported by the aftermarket.
