The engine selection depends greatly on track conditions and car you are running. Our team drives with 5pt on buggys (except me) as it's best match to our tracks and they are also looking for that initial kick. I'm satisfied with the r-spec and with M2C clutch it's great thing to drive. I also run the 5pt on my truggy and happy with it so there's plenty of pwr packed in that engine. If you compare r-spec and 5pt you can clearly say the 5pt wipes the floor with the r-spec when speaking or low-end punch.
For cheap alternative get the 5pt sleeve and make a frankenstain R-spec
The 5PT Sleeve+Pistion are an alternative. The reason I had purchased the GO 3 P R was because I was told that this engine puts down more power than an OS V Spec. The V Spec is a better engine in almost all areas, more bottom end, mid range and lets no forget what an awesome carb OS has/is renowned for. Did I mention how awesome OS carbs are….
