Let's take it one step at a time! Definitely go forward with the Turner stroker. If you've got the $$ to burn, get the stage III head with all of their magic. Also get the 2-pc group A header, a Borla exhaust system, the Motorsport big bore throttle bodies (48mm vs. 46 mm) and the 11 lb Motorsport flywheel (all available from Turner). This set up will get you close to 270 hp from a nice, durable, normally aspirated engine. You will be happy!
If you're not, then you can consider supercharging. However, keep in mind that (and I don't care what ERT or anyone else says to the contrary) you need to bring the compression way down (about 7.5:1) if you want forced induction on an S14 (not an S23!) whether we're talking turbocharging or supercharging. Otherwise, your motor will not last. This would make the whole 2.5 project a total waste of $$.
Go with the 2.5! I have one with all of the above mods and it goes like a scalded cat.
: Wanted to know what you all thought of the new ERT supercharger available for the E30 M3. They claim it produces 290+ HP.
: I am in the process of purchasing an M3, and the first performance mod I intend to do is to convert the engine to a 2.5L with Turner Motorsports EVO perf. kit. I will follow with exhaust, intake, etc. What are the benefits of having a naturally aspirated, but modified S23 engine as opposed to a supercharged, and modified S23? I know for sure that I want to add the EVO kit and other mods, but Supercharger? Please share any knowledge you have about the subject (especially those of you who may own the ERT supercharger).
