Great info! I think that's super helpful for the purchaser. Turbo link below - it's a Z54 journal bearing edition of the ZFR6758. The 6758 can safely go into the 400's at the wheels with light supporting mods and a strong tune on good gas if more power is necessary. In other words, this turbo will spool a little slower than a stock k04 but has a LOT more potential throughout the power curve even as it sits at 328whp. In the vids, you can tell the turbo lag is not a real world issue. This build IS fast and well put together, no doubt.Here's the information from back when the turbo and tune were purchased. We selected a ZFR turbo for Matt but to be honest, I don't know if I could identify one by sight.

Here's the turbo we pulled off next to the turbo we installed:

You're right about the tune being conservative but one factor that needs to be taken into account is that the car was on the dyno in August in Texas. Also, the dyno we used tends to show conservative numbers compared to others in the area which is alright because it is used as a tuning tool for dirt track cars and not for getting the biggest numbers possible for bragging rights. With the way it pulled on Roman's GTR, I wouldn't care what the numbers say.

I'll bow out from here, good luck with the sale!
Edit: Like most folks here, I want these builds to sell for $50K ...so I'm in the same camp in that $25K is a steal!!
