I have a stock turbo in my 91 legacy with auto trans. I'm upgrading the exhaust and probably the turbo as well.

 

What turbo is on my car? Is the WRX unit a better selection? Are the up pipe and down pipe flanges the same?

 

I plan on doing some drag and rally racing with this car.

 

I was planning on switching over to Garrett but it would be easier to just stick with the Subaru stuff (if the flanges match up).

 

any ideas?

vf11 on the leggo

tdo4 on the wrx

 

they are the same flanges

 

intake requires some moding on the tdo4 but i am confident that you can do it

 

i suggest a vf22 or vf39

 

a td04 isnt much of an improvement

 

try a 16g or 18g
