im, in a way, in the same position, im looking for the all out best motor for around 200, ive ran the os tz and like it, but i like the specs on the jlr also, i ve heard that you have to change the connecting rod after a gallon though, is there any truth to this? does any one know hp/rpm for the rb junior? i race at a some what small track (120x80) so i dont think i need tooo much power but id rather have more than not enough. any suggestions would be great.
