Ok so I am looking to most likely go with either the gt3076r or the gtx3076r. Can anyone explain the biggest differences and which they would prefer to achieve about 450 whp. I threw the other 3 turbos in as well if anyone feels there is a reason to go with one of them as well. Sometime down the road I may like to go higher then 450 whp, but atm the is what I am looking for. And also the vehicle will not be driven daily, just on nice days and/or weekends. Thanks for your input and advice.

 

I am not a turbo expert but I think that GT 3076R will probably start to lose efficiency at about 500 to 525 wheel horsepower. The GTX 3076R will make about 50 to 75 wheel horsepower more before it starts losing efficiency. You can look at my signature for results.

 

With a good manifold you can make 500whp on 93 oct at 14psi with the GT30/76r

If you want more power then you need to go bigger or go GTX

 

i would go with the gtx same turbo just more efficient with the billet wheel

 

Thanks for the input, still not 100 % sure what ima do though

 

GT3076R will spool fastest and easily make the power you want, for less money. Done.

 

spool faster than a gtx3076r? nope

 

The GTX series is better all the way around, anyway you look at it.

Just $$$ to consider at that point, b.c they certainly aren't cheap.


The A/R however is entirely up to you, but if you have already made the choice on the 30, .76 is your only choice out of what you posted.

 

Gtx3076

 

Gt 30/76 < GTX 30/76 gtx will spool faster
