06Legacy2.5LManTran Posted February 18, 2015 Share Posted February 18, 2015 So I bought a Legacy knowing I wanted the GT, but my budget could only afford the non-turbo 2.5 Man Tran. Now I've landed an awesome Job and have some funds to pour into putting a Turbo on her. I'm in the R&D phase of my plans and was hoping someone could offer some advice on how to Turbo my Engine.

Merc6 Posted February 18, 2015 Share Posted February 18, 2015 How much money is there to burn? Not sure you can slap a turbo on the n/a and make a save bump power worth the price of the kit. Not as simple as grabbing gt headers,up,turbo & lines,down and a tune. Cheapest way would be find a good running GT as the resale value of the n/a will go down quite a bit with turbo swaps unless you could care less about that at this point. The amount for a legit swap will be the price of a mid to high mileage STi of same year. 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...
ras06LGT Posted February 18, 2015 Share Posted February 18, 2015 It's been covered many times on the board with the same advice. If you want GT power buy a GT. The money/time needed to properly convert the 2.5i to a 2.5GT is not worth it. Link to comment Share on other sites More sharing options...
dr_sharp Posted February 18, 2015 Share Posted February 18, 2015 I'm intrerested too. I've just landed an awesome job also. It is just awesome enough to spend a bunch of money doing stupid things to a cheap car, but not awesome enough to just buy a nice car from the get-go.

Akasa Posted February 18, 2015 Share Posted February 18, 2015 Here's a quick rundown. The GT engine is DOHC EJ255, the 2.5i is SOHC EJ25. To do anything logical with a turbo setup you need the DOHC engine. Your 5MT is a different 5MT than the one in the GT. You have different gear ratios, and the 2.5i manual isn't as strong as the GT manual, so you'd need to buy a Turbo 5MT and a different clutch, possibly a different driveshaft too. That's just the start, you have so far to go to make your car into a GT that you'd be better off selling the 2.5i and buying a GT. Link to comment Share on other sites More sharing options...
Mike07LGT Posted February 18, 2015 Share Posted February 18, 2015 Buy a GT. You cant afford to turbo the N.A. if you cant afford to buy a gt to begin with 03 WRB WRX (RIP) 04 JBP STI (sold) 07 DGM Legacy GT (RIP) 12 OBP STI (DD) Link to comment Share on other sites More sharing options...
turboboost Posted February 18, 2015 Share Posted February 18, 2015 This has been covered a number of times, and the consensus is always "Sell the NA, buy a GT." You'll be pouring money into a project with an unreliable and most likely disappointing outcome. Since you're in a better place financially now, sell the NA.. buy a GT.

06Legacy2.5LManTran Posted February 19, 2015 Author Share Posted February 19, 2015 I'm intrerested too. I've just landed an awesome job also. It is just awesome enough to spend a bunch of money doing stupid things to a cheap car, but not awesome enough to just buy a nice car from the get-go. Subscribed Its like you are in my head! There is a chance that Quantum Entanglement has transmitted the information from my life to you! Or you are clairvoyant. Either way I was discouraged by the others saying to just buy a new car, but as you all can see, dr_sharp and I both think this is a worthy investment. On another note I think I'll just save up a few more years and Buy a GT as others recommended. I know this decision comes as a huge disappointment to those wanting to turbo their n/a (namely dr_sharp), but the advice is sound. Thanks!

Merc6 Posted February 19, 2015 Share Posted February 19, 2015 You will thank us later as you see how much we spend just trying to keep our cars on the road and they came already assembled with turbo. 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...
Leviman Posted February 19, 2015 Share Posted February 19, 2015 2.5i to 2.5 (well, XT in my case) owner right here. I'm a convert! I actually got a really good deal and upgraded for $0, sold the 2.5i for more than the XT cost. Just shop smart. The only swap I'd say would be worth doing would be to get a half cut of a EDM 3.0R spec b and swap that over in the US. Mmmmm Link to comment Share on other sites More sharing options...
nightmonkeygt Posted February 19, 2015 Share Posted February 19, 2015 The brakes are different too. The calipers and rotors are a bit bigger I believe. Link to comment Share on other sites More sharing options...

Aswell as the heads, the compression ratio for a non turbo will be way too high for a starter so unless you'd be thinking of running really low boost things would get messy real quick. 2000 Legacy B4 RSK - SOLD 2006 Legacy BP5 GT Spec B wagon - Garage Thread 2011 VW T5 van 2.0L of turbo diesel awesomeness Link to comment Share on other sites More sharing options...
