the biggest issue is not being able to name the spec, the thing with these cars/ engines is its quite a niche market and buyers spending that sort of money will want to know exact specs.

i mean, uprated rods & pistons? what does that mean? custom made CP pistons or standard mahle's? fardon rods or standard?

i suspect a tuner has cashed in and billed for "uprated" parts because the customer wont know the difference
