Just bought myself a nice xr2 with,

New pistons
All bearings
Lightened & balanced bottom end
HP oil pump
Twin 40DCOE's
Kent cam
Port matched head
Magnex manifold and stainless steel system
Set up and rolling roaded at 130.8bhp

And it's plenty for now. The cars so light but its not really about the speed or power, the noise of the Twin 40s is bliss. A squirt in 2nd through town makes people jump against the walls! Only down fall is its probably good for 25mpg on a good run!
