Ok so i have a IX turbo and an VIII turbo that has been converted to a 20g. I am going to put one of them on right now and sell the other. I am not converting to FP (would rather just spend more and get a bigger kit) This is going on a VIII with 9.8 hotside turbo with stock o2(anything would help from this). Both turbos i have sitting have 10.5 and aftermarket 02's. Trying to figure out which you think would would be better because i have heard that the VIII's when converted to 20g are a$$. lemme know what you think.

Oh yeah i have all supporting mods for pretty much anything. Turbo is the last thing i am touching.

 

I would do the 9 turbo and call it a day. I bought a brand new modified 20G-9 turbo and it was very hard to sell due to history of that turbo. It gets inefficient near redline from reading posts about the 20G-6 blade compressor wheel. This is talking to Buschur myself.

 

The turbo on the EVO IX is a great factory turbo. Those are the factory turbos people can more 30-50 more hp than a factory EVO VIII turbo.

 

yeah i have heard that they fall off towards redline. Anyone else have an opinion? Just dont know which would give better results.

 

try them both out. I would say stick with the stock IX. It works that good.
