Turbo swap on Legacy

DRNWAGN · 10-02-2007, 10:05 AM

Hey guys,
Been out of the game for almost a year now but looking at maybe buying a L-GT now. None the less, I am just curious about this and after doing a search I did not see anything. I know that I have seen a Legacy wagon with a GT30R kit on it but was wondering if the stock turbo could be swapped out for the more traditional WRX/STI turbo set up. I mean, if you got all of the exhaust components (man/up/down pipes, turbo and ran an fmic) would it all bolt up the same?

I like many of you have been exploring different upgrade options as I have in the past and while I am sure there are other Leg turbos out there that one could use, you still end up running the smaller tmic. I know Perrin makes a larger tmic mind you but just figured it would be pretty cheap to pick up the exhaust components used from other members if you will and swap to the traditional set up. Once that was done I would think that you could probably run a WRX/STI map to get it running to at least get you to a shop to get tuned.

Has anyone done this? Like I said, I did a search a couple of times but really have not found much of anything.

You won't get anything upgrading to WRX components I think, but STi - yes I think it can be done. Check out legacygt.com - if there's anyone who's done it they will probably be hanging out there.

The STIi VF34 is a popular upgrade for the 05+ LGT'ers though, along with the uncatted up pipe from the STi, so if you want to use STi components, then by all means. I know a couple of guys over there that use the GTxx series of turbos too.

Can't use the TMIC though, it's different routing.

For EM...depends on what kind you're going to be running I think. Cobb AP is popular with those guys but not sure if they use the same map.

Well, I was asking because I just happen to still have my full exhaust (stock) off my WRX and my header (cracked borla that I could get welded) from my older FXT. That being the case, I could bolt on a different turbo almost right out of the box. I realize that I would need a different intercooler but was just thinking about it. Not sure what will happen yet as I am still trying to talk the wife back into it all.

I would think that the WRX Cobb maps would work on an AP for it. This of course is purely hypothetical mind you. I know I had an STI map loaded up on my FXT at one point.

I have done the VF39 before and the 34 is not much different though a little more durable. Not sure if I would do that and settle for the 300 awhp again or just go big with a 30R this time around. I mean, I would have to run an FMIC no matter what turbo I swap with so why not go big. Well, maybe a 20G anyway. Who knows. Gotta talk the wife into not serving divorce papers after I buy it!

Would love to do the Spec B to get the 6spd but don't think the wife will want to fund the difference. Might just be stuck with the ol 5spd! That of course limits turbo options a bit.

Oh, on a side note. Been pricing cars through a place called autotroplis.com. You pretty much type in what you are looking for, they inturn send your requests to 2-4 local dealers who inturn send you quotes. I got a quote today for an 08 LGT w/ black leather and 5spd man for $25438.00 From what I have seen at the other dealers that is not that bad. They still wanted $31.6k for the Spec B though. That is definitely a difference in payment!

Those are still pretty good deals though. However,

Person I know really well where I live is selling his practically new Spec B (4900 miles) for $29k.
