Hey all,

I recently purchased the Hpi Evo+ M3 body, and would like to upgrade the engine. Its my understanding that the car fits a 18, 3.01cc size engines. Are there any recommendations for a powerful preferably 40,000rpm engine that won't require too much customizing to install? I'm looking for top end speed and acceleration.

All feedback is greatly appreciated

OSMAX 18TZ

Thanks, I purchased the 18tz pull start but what header could I use on it for the rs4 evo+?

Did you ever get that 18TZ running?

No, I have the car and engine on ebay. My mugen mtx5 and Serpent Cobra GT have been taking most of my time. However, we were talking about running the combo at the hobby shop today. If it doesn't sell, I'll hook it up. What are you running?
