Cup Racer engine (738) in 172

[Joepster]

I have seen a 738 Cup racer engine for sale.

Does anyone know the difference between this engine and the standard 172?

Right know i'm running 172, v6 airbox, 182 manifold, KTEC full exhaust. Will the Cup racer engine give me more power (after remap)?

When was it last rebuilt? Second hand race engines are such an unknown quantity.

The box is what you want.

Airbox you mean?

In theory no difference as they are meant to be standard, in practice might have some very slight tweaks depending on who built it, but still going to make only a tiny difference, you would be far better off just fitting cams or an RS2 to yours!
