66 VGT and 190s...too much air?

Im going with the 190s and a powermax right now because thats what I have, but I was offered a 66 VGT for $1000. Is a 66 VGT going to be too much air for 190s, its a daily driver..not too much towing. I really dont want to sacrifice too much driveability..

I think a 66mm turbo would not be too much air. I do think that it will be laggy so I also wouldnt tow with it but I bet it would still be streetable. A diverter valve may help with spool up.

It is actually a 64.7mm inducer, does that change things quite a bit?? another dealer had a typo between the stage 2 and 3 kits, so I double checked the manufacture, and the stage 2 shows to be 64.7mm inducer. Its made by TEC, turbo engineering corporation.

Wait so do you have the complete specs of the turbo you want to know about?? Because there are different sizes in turbine wheels, A/R ratios from housing sizes, and flange options as well. So my question is what is specs on the turbo you are looking to put in??

The Stage II/Silver Lighting is a 64.7mm inducer/88mm exducer Compressor Wheel and flows 60lb/min at a 2.5 pressure ratio. Also, has a efficiency of 72%

thats all of the specs that the manufacture has on there website

Why not try out a batmowheel in your powermax before doing a full turbo upgrade? I am not a turbo guru by any means but IMO I would not get a VGT turbo any bigger than a powermax. I would start looking into an borg warner EFR or S300 based turbo with a diverter valve if the powermax is not big enough.

Ok well its a 64mm turbo and that would great with your 190s IMO and if you had a diverter valve in there as well, I think you could still tow with it. I would get a second opinion especially from 06powerstroke06. He is great and knows a ton. Hope this helps.

its a VGT not a non vgt, and your powermax is going to be more reliable... but I would go along with the comment to go with a batmowheel in the powermax and you'll be a happier camper

big vgt's are a joke

A non-VGT turbo will be more laggy than a VGT for sure but a diverter valve will help with that and the one he is looking at will flow way more air than the powermax and will use way more fuel than the powermax will as well and since he isnt going to tow with it, it will still be very streetable.

Wait so we are talking about a big VGT? Yea stay away from those. A batmowheel powermax will be way better for what you are looking for IMO. Sorry for the confusion. I thought we were talking about a non-VGT turbo.
