I know a guy who had a 2001 Outback H6 and wanted to boost it (only to about 7 or 8 psi as I recall). The tuner talked him out of it when he found out that the engine has a single exhaust port for each bank of 3 cylinders. He was concerned about temperature rise inside the head (I believe).

 

IMO, you are taking your chances boosting the 2.5L engine, unless you do a full build up. You might try your luck on finding a turbo'd engine from a wreck, or an importer.

Hi,

 

Thanks for the info. Anyways could you find out from your friend exactly what his tuner told him? I'm alittle confused because I thought the H6 was a DOHC 4 valve per cylinder. Well if you could let me know that would be extremely helpful.

Thanks

I can't remember off hand if the engine is single or double overhead cam (but single I believe). I'm sure it is 4 valves per cylinder. However, none of that is really relavent to my comment. The exhaust gases from all 3 cylinders are brought together inside the Aluminum head to a single port before they go into the exhaust manifold. That's all I was commenting about. I have not personally verified this, but I have not heard to the contrary either.

Hello again,

I understand now what you were saying. I didn't get that one port deal but I do now. So would you think about building a jdm STI motor and droping that in instead would be a better idea or is the whole concept of beefing up a legacy kinda ludacris? Well let me know what you think.

Thanks again
