What's the difference between these two turbo's?

Is it worth paying extra for the SPL?

 

There exactly the same except the SPL has a much bigger compressor wheel. 76mm vs 70mm for the KAI I think . Both are ball bearing and both have a 1.0 hotside. Pls correct me if I am wrong.

 

Is ot worth paying extra for the SPL? That depends if you are going to need the extra compressor flow. The SPL is able to support 1000hp and the KAI is around the 800-850 mark. If your not going for 1000 hp then there's not mush point getting the SPL.

 

It is my understanding that Ball bearring is an option on both of those turbos. They dont' come like that standard I don't think.
