thank you very much for the help. Will I have to change out the impeller with the new pulleys or should I be good?

It depends on your boost goal. But for other parts in its internal, the stock head unit won't hold up for long if your using exactly the same setup as that redondoaveb is having. He ran and will be running 928's rebuilt blower.

Of course the 2.85 is going to overspin the blower so the ceramic bearings would be a good upgrade. But, Seb had told me that he knows a few people that are overspinning it with the stock bearings and they haven't had any issues.

I got one blown away with oil coming out of the shaft seal on stock internal for that RPM. So I'd not feel comfortable without the internal upgrades. With the Si and 9lb pulley, he will be seeing a little less than 11psi. This would suffice for most of the owners dding their cars.

True. That combo netted me 540whp on e85

Do you have the Sci or Si blower. If you have the Si then I wouldn't change the impeller.
