jardev Posted March 18, 2014 Share Posted March 18, 2014 I have a 06 Legacy GT. It's completely stock as of now. I want to do some modifications to it and want some opinions on the durability of the auto transmission in it. It only has 60k in millage. I want to get somewhere around 300 hp at the tires. I have had some folks say the tranny would not support it and others say that it would not be a problem. I am sure I would need a bigger turbo to make this happen but am not sure that with an auto transmission the car would handle that kind of power. My over all goal is to understand some views on the transmissions and if it's possible or already done with my current setup with modifications added. Thank you all. jardev Sent from my iPad using Tapatalk Link to comment Share on other sites More sharing options...
jeffy2.5xt Posted March 18, 2014 Share Posted March 18, 2014 Yes the auto is good to do it. Hexmod and trans cooler will be your best suggestions. There are a few on here making that power and one guy making 5something if I recall and he was working on trying to get 9 sec qtrs. Link to comment Share on other sites More sharing options...
jardev Posted March 18, 2014 Author Share Posted March 18, 2014 Damn with an auto transmission? That's amazing. That makes me feel better. I am looking to get at least 300 and he is at 5? Sent from my iPad using Tapatalk Link to comment Share on other sites More sharing options...

Max Capacity Posted March 19, 2014 Share Posted March 19, 2014 VF52 with fuel pump and injectors, catless up and down pipe should get you there with a good tune. Remove the banjo filter or if you can both of them. Learn how to check the oil and keep it topped off. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs.

jardev Posted March 24, 2014 Author Share Posted March 24, 2014 I just installed a cat less up pipe and now am looking to get the turbo back. In the install process it looks as though the stock turbo has a bit of shaft play and has be depositing some oil in the down pipe. I think I want to replace the turbo next. What do you think for the money? Sent from my iPad using Tapatalk Link to comment Share on other sites More sharing options...

WhiteMonster06 Posted March 24, 2014 Share Posted March 24, 2014 Here is my mod list, after a good tune I'll be seeing roughly 280whp. With injectors you'll see about 300. But 300 would be maxing out my turbo.

You might want to consider that or open source. Either way, you WILL need a tune. only difference is mine is an 06 5MT not automatic. Link to comment Share on other sites More sharing options...
jardev Posted March 24, 2014 Author Share Posted March 24, 2014 That looks like a good set up. So far all I got is a grimmspeed up pipe. And looking to do a turbo or turbo back. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
WhiteMonster06 Posted March 24, 2014 Share Posted March 24, 2014 I'd go with the turbo back and stage 2 tune before you decide to go further. Take it step by step to see how you like it. Then adjust your wants/needs from there. Link to comment Share on other sites More sharing options...
jardev Posted July 30, 2014 Author Share Posted July 30, 2014 I am torn on getting a turbo back on my 06 or just a down pipe. Not sure if it makes a difference at all. What do you think. Link to comment Share on other sites More sharing options...
AF_3C2 Posted July 30, 2014 Share Posted July 30, 2014 Do just the downpipe unless you have to have the sound from a full turbo-back. Your wallet will thank you..... Remember that the downpipe will require a tune- if it is the only thing you change you can get away with an OTS stage 2 map, but pro-tune will be much safer and better for your car.

Merc6 Posted July 30, 2014 Share Posted July 30, 2014 I did down pipe but kept the mid pipe. I took the factory mid resonator off and replaced it with 2 bullet style ones eventually. I went with multiple combinations throwing money experimenting till I found the sound I wanted. Straight pipe mid resonator to stock cans sound like crap, avoid that route. Best quiet but noticeable sound for somewhat cheap was stock mid resonator with 2 mufflers and tips of choice in place of the heavy triangular stock cans. Splurge a bit more and get rid of the tiny Y for a larger Y and pipes back. I'm somewhat happy with my current setup but may change it again in the future after the build is done. 2005 Satin White Pearl Subaru Legacy 2.5 GT Unlimited 5EAT (Project Car) 2019 Agate Black Ford Explorer XLT 4WD (DD) Link to comment Share on other sites More sharing options...
