after a few days trying to decide in which direction to go with the engine build myself and maximum motorsports have settled with nizpro. it was a coin toss between xtreme/atomic & nizpro.

fyi xtreme engines feature custom diamond (us brand) pistons with much longer skirt design than atomic (brand unknown) making them quieter but also more reliable in the ol' piston to bore clearance and both use the atomic "fat" h bean rod in the 950kw engines.

having favored this option ultimately it was hard to go past the product & experience of nizpro. the entire engine, including flywheel, clutch and harmonic balancer (in turn each one upgraded with a custom billet or ceramic equivalent) has been sent to nizpro for their stage 3 engine package. we have also ticked the "stage 4 1000hp" box in the order book to not only get to the desired hp target but exceed it on the shy side of 600rwkw with driveline components to match!
