So the real differenace bewteen the 20g8 and 9 is that the 8 has a 9.8 and the 9 has a 10.5? other than that arent they the same?

 

The 20g-8 can be had with a 9.8 or a 10.5

All 20g-9 has the 10.5 and uses the evo9 turbo compressor.

Well, a 20g-8 can have a 10.5 hotside, because 05s had 10.5 hotsides.

The 20g-9 is a stock IX turbo with a 20g wheel and also has a 10.5 hotside like the 05s. The stock IX turbo is NOT the same as an 05, though, because it has a larger compressor cover, so your statement is not correct.

Now, you should be really confused, Spooldyou!

 

What is the max hp you can get out of a 20g (ix - with all the supporting mods and 93 and meth?
