Which 20g compressor wheel? There are probably a dozen that are 52.65/68mm. 20g is now just a form factor, not an actual product anymore. At one time all that existed was the MHI 20g for a truck (with TD06 turbine), but no one uses that wheel anymore. I ran the 11 blade GTX style for 20k and just switched to the EFR style 7+7 blade. The GTX style had an extended tip to 71mm and the EFR style has an extended tip to 73mm. I never run stock TD05 turbine, but instead use the 9 blade TD05 which provides more top end flow and spools just as fast.

Spools nice and good top end power tho I'm going to change out turbine housings for a td06. Td05 housing makes it surge pretty bad. Boost is basically on/off but there's quite a bit of surge.
I could probably do an antisurge housing and fix it, but I'd rather have the better top end flow with the td06.

I would go with the TD06SL2 9 blade turbine wheel. Going to a full blown TD06 is going to kill all of your spool. The 9 blade TD06SL2 flows more than enough for a 6+6 20G, and will keep your spool decent.

Also, I don't know what your using for boost control and I am only familiar with tuning the EBCS on the Evo X.... but you can tune out surge assuming your wastegate spring isn't too strong.

Yah I just shortened it, but the tdo6sl2r is the gittup I'm looking at.
Very nice numbers! And as stated above there’s about 15-20 different Billet 20G compressors. Looks like your 6 blade works perfect with your setup. I’d also recommend the 9 blade Td06sl2 if you ever plan to upgrade. Could get very close to 500hp
