At my last OT session it looks like I dropped cylinder #2. Its at the shop and they are trying to figure out what happened and why. Anyone have any suggestions for a new motor/build that is primarily street driven with 5-10 OT sessions a year? Current setup: 03 Cobra stock longblock with KB 2.2 at 17PSI 530/500 RWHP/TQ Tuned by Rick at Amazon Tuning I'd like to keep the KB and retain a similar power level if possible for a good, reliable engine. My budget is pretty much whatever I decide to do with the car, so I'd say anywhere from a basic rebuild to 6-8 for a good motor build. Any info on things to do/not to do with a new build? Thanks for any responses!
