Yes.
They make race car parts and engines.
They make race-prep SR20DE normally aspirated engines for Touring Cup racing. (costs about $50,000 for the engine)
They also make an SR20DET racing engine which goes for around $80,000
You cant run these in your car as these are race specific engines that must be rebuilt after every other race.
They also make pistons and stroker kits (the ones JUN sells are actually made by TODA)
They also have cams, race cams, and flywheels for our engines..
