nope, there are plenty of people running 3" turbobacks with a ko3.

 

I am going to get the kit from 034, I am also getting there high flow manifold as well, i hear atp designs something wrong so you can't bolt it on correctly (on occasion, or messes up should be a better word), you and sean even say they are dumb if i remember correctly.

300whp is fine with me, and since I'm going to do the actual installation myself, then a direct bolt-on to my down pipe will be nice instead of customly working something out.

I do see your side of the arguement though.

 

You do realize that atp modifies the turbo right? So its still a atp product. You should go find beer mod's ko4-15 thread that died out about a week ago and read my last post i believe it was. You will find money well spent there. But i think i already gave you or someone else that list pretty much in pm's

 

i wish i was so lucky

ill go take a look at the thread.

i did not know atp modified the turbo, but i believe it was the manifold they made that they had some issues with, not the turbo itself like you said. but i will be getting the 034 mani because they are good.

 

ps- you gave all the info for a T3 60 trim setup.
