Isn't that the truth. I've gone the MR230 route with some differences in terms of the specific CBE and certain intake piping decisions. That's not been the least expensive route, but I think it's comparatively safe. It runs well on our pump gas and at the track I'll bump the octane with Torco to (hopefully) deter potential detonation. Add to that suspension and engine cooling adjustments, and this has become a not-so-cheap exercise in personalization.
Here's the thing: Even applying moderation to the HP/TQ enhancements and working to help reduce heat-related damage due to track day abuse, there is a risk that the engine will crater. Look at what [MENTION=688]Sourskittle[/MENTION] is documenting in his
epically unfortunate thread.
Now, if you strictly daily drive this car without testing its limits, then the MP215 or Cobb equivalent is all you need to liven up the little critter. That's PLENTY of daily-driver scoot for this car to be entertaining. Getting on the freeway is a hoot and there's plenty of TQ for corner exit in the twisties..plus: warranty is completely preserved (in the case of the MP215 setup).
That's just 2 cents from the peanut gallery. YMMV.
