hey man I was just wondering how much hp would the GT2871r get at 9psi and how much PSI would it take to get to 400hp??? and if it cant you what would you suggest upgrading the turbo to???
Also do you now how much you roughly spent to get your car running to 306whp @ 15psi???
Currently I am trying to get all the information I can get. So anything would help. Also the gt2971r comes in two common sizes the A/R .64 and .86, does the .86 really make more noticeable spool-up lag and how much more hp will the .86 get compared to the .64?
Also what is the difference between the Garrett GT25/40R and the GT2871r hp and spool up wise?
