So i'm seeing a whole bunch of t70's on ebay for $400-$600, and i've seen 2 differnet ones. One is with a 60.5mm compressor wheel, and the other is 70mm. I see claims of 700+RWHP with the 70mm, and just 650HP (asuming fly wheel) with the 60.5. I tried asking the sellers about this, but never got any response. would the 9.5mm diffrence in the wheel actually be able to equate to ~25% difference in power(saying 700rwhp = ~ 825 fwhp)? Or should i be able to run the 60.5mm up to 700fwhp. The main reason is cost, since the 60.5mm are much more available and are cheaper by $200.

I'm going to do a rear mount using the .84 A/R and shooting for 700fwhp with a 355.

 

If they are the ones from stone mountain racing or SS Auto chrome then they are junk and arent true T70 turbos.

 

Stay away from any ebay turbo, stick with a name brand such as precision or garret, trust me on this. having a turbo explode on you possibly sending shrapnel up into manifold and inside the motor is no fun.

 

Real MasterPower turbos aren't bad. However like RealQuick said, the ones that are being sold on ebay through ssautochrome and stone mountain are allegedly cheap knock offs. You can get real MasterPower turbos relatively inexpensive from forcedinductions.com, or forcedfab.com

 

.84 what? turbine and compressor, just turbine, just compressor??

 

Yeah cuz .84 on the exhaust is tiny

 

, i think you just might be able to do it though.....but i think you should be up around 1.09 around about there. im not sure on exact numbers right now, its getting late.
