Im putting in a turbo from an 04 STi, cause the guy is putting in some crazy big one.

My question is will my stock WRX IC be enough to cool the turbo or will I have to get the STi one or a comparable sized IC?

Also besides putting in a set STi pink injectors an STi fuel pump, perrin Up Pipe and a Utec is there anything Im missing to get full potential? (besides a 2.5 swap)

Thanks

 

i mean VF-39

 

stock WRX IC is fine up to 300 whp I believe

 

But if you changed to a different IC, such as the Helix or Turbo XS, you would gain more power when properly tuned. Nothing wrong with leaving the stock one on it, but to reach the full potential, I would get a new TMIC.

 

if you dont want to spend a alot of money on getting a aftermarket tmic or a fmic you should get a JDM STI Version 8 TMIC it is bigger than a USDM STI TMIC but i am not sure what are the real Dimensions are, and how much bigger is the JDM STI Version 8 TMIC to the USDM STI TMIC if their is anybody who knows the dimensions of the JDM STI Version 8 TMIC

 

JDM is 15% bigger than USDM STi intercooler, but the US one fits better. USDMs are also significantly cheaper, because they aren't "JDM y0" and therefore score low on bling.
