VISHNU Single Turbo UPGRADE 6262 to 6466

This is more for the SINGLE TURBO guys.

I'm considering upgrading from a 6262 to a 6466 and was wondering if any of you guys that have the 58mm little guy want to go to a 6262, I have a fresh (Very Low Milage) one.
Let me know ;-)

You'll like the 6466. Don't have the 6262 to compare it to but i like the 6466

What are the main attribute differences between the 6262 and 6466?

Compressor wheel and turbine wheel size. The 6466 is also only available as ball bearing. Depending on how old the 6262 it may or may not be the newer CEA turbine wheel. Judging by how long the vishnu kit has been out I would assume Jmars has the CEA wheel. Something I noticed myself also is that the 6466 appears to have a different compressor wheel design than other variants in the same line up.

Compressor and turbines both different. Compressor inlet is 64 vs 62mm and turbine is 66 vs 62. Those are just rounded whole numbers. The bigger exhaust will help out in the top end. If you look at the compressor wheel closely it is of a newer age Swept blade, like most turbine engines. This allows the turbo to flow more air with out actually making the radius bigger

I haven't gotten my kit yet, but have yet to see where the wastegate attaches to the system at. Did they modify the turbine housing and connect it directly to it? If not, I would throw your 6266 up on the evo forums as well.
