I want to up grade my turbo I need more info on that turbo 4272 With the billet wheel.
Any One using that turbo ??and what will be the spect on that turbo ??and options for it

 

I have read and talked to a few people and they said you can get it in .90 1.10 1.25 1.44 ar and that is about all i can get out of anyone i think t1 is running the 1.25 ar right now and i think i have read some were that miller is running the 1.44 so may call both of them and ask. oooo and it is kindy pricey.

 

What turbo do you have now? I sent a Garrett GT4294r to Miller to get upgraded to the GT4272 Billet. I just measured it the other day, The inducer is actually 71.50mm. Exducer is 102mm. They Swapped the compressor wheel, housing and backplate.

 

You can do that i have a gt4294r now and i would love to do this. What kind of money was it to do that.

 

I have now bullseye s372

 

It depends on the shape of your current turbo for the price. I paid around 2000.00 because it had a damaged exhaust wheel.

 

The upgrade is the best way to go if you have a 42r currently, I keep the full units in stock just so nobody has to worry about the wait between runs that precision does. The upgrades as courtney said all depends on how good of shape everything is in.

Right now there is NO better 72mm unit out there.

 

Pm send miller and thank u guys for
the info

 

What is the avg. price if the 42r is good.
