Anyone heard of a JP S5 5 port ? i cant find it in JPracing.com website.
What are the differences between a JP S5 5 port, and a RB Rody Tuned X12T 5 port Turbo in terms of their modification techniques to their crankshaft, sleeve, piston...conrod...etc???
Nope RTO's ain't legal unless you race in the UK,Asia Or Down Under. Neither is the rare 9 port Eagle Version. However the RTU generation 1 engine is. It is the engine that started the mod 12 motor craze 3 years ago. It also was the one that caused all the controversy at the US nationals in texas.
All then RTU's are legal at the moment gen 1-3.
Unfortunatly no new engines are available from me at this time.
Before somone asks the RTO is the open 3 port version of the roar legal RTU produced by Richey Performance Motorsport and I am not in texas never have been I live in Michigan (I had a distributor in texas at one time) The Eagle is a Nine port handmade MT 12 engine. The Supersonic 15 (i've never talked much about it)was an RTO 15 size small block in an MT 12 case. Only one was ever made. It is still in the tool box. It was in an Impact for a while.
Just here to give the world grief.
