Question Newbie Forester XT question

I am getting back into the Subaru market.

I'm looking for a Forester XT 5spd, preferably an 07 or 08 Sport.

I would like to find one that has been modded somewhat.

The questions I have are:

1. What is the best way to minimize turbo lag? I used to have a Baja Turbo and have test driven a few stock XTs. My biggest complaint with both are the time it takes to build boost.

2. Is a FMIC a good solution to increasing capacity on an XT? And if so how does the switch to a FMIC affect spool up? Call me an old fart but I could do without the hood scoop but realize the bigger the IC the bigger the scoop needs to be.

Hmmm go stage 2 and you'll have spool just the way you'd like, also a front mount will increase the time it takes to spool your turbo. Longer distance for the air to travel through the piping.

Plus your hoodscoops are dope

Wrong. There is way more info on this site. What sf.org is only good for is fitment of impreza bits on the fxt or exterior body upgrades. Outside of that performance wise, nasioc is the place to research.

Spool should not be an issue with an xt that isn't heavily modified. I drive an 06 fxt with a vf39, sti top mount and some stage 2 goodness and my boost threshold is about 2800rpms, so I would say that you dont have to worry about it. As far as fmics go on the xt, I havent tried myself but being that there are no kits to speak of and it requires a lot of custom work, the consensus is that an fmic setup on an xt is not worth doing unless its making big power (rotated) and required such a setup.

I wish you luck sir, I was looking for an 06-08 FXT 5spd before I bought my 06 WRX wagon; they are hard to come by, unless you are looking for one with 100k+ miles.
I have a WRX so it's like comparing a machintosh to a red delicious but from what my research told me - if you are looking for more out of a FXT, TMIC on the forester should be upgraded to an STi TMIC, a FMIC will increase turbo lag not reduce it (more piping). the setup that TheStepfather has is pretty typical for WRX's. Also the Baja turbo is quite a bit heavier than the FXT, somewhere in the neighborhood of 500lbs, so the FXT should be quite a bit snappier. Simply getting the stage 2 goodies should make a noticable improvement. Again, I'm going off what I've read, I don't have any personal experiance with changes to the FXT - I did test drive/flog a stock 07 FXT and from my experiance there wasn't a lot of lag, but each car is different.

Good luck, you should be able to get some answers on here.

This video was taken by the shop that tuned my car, not very detailed but it gives an idea of how fast boost comes on.

sure, except for all the unique body and interior bits that can go wrong, or when you try fitting something like a steering rack or modding the suspension or brakes, then you find out how nice it is to discuss with fellow FXT owners.

Yes, this site is great for engine and exhaust info, theres more experimentation and hard core power upgrades done over here.

Anyhoo, cary on...

Head over to subaruforester.org and read the sticky "how to"...
A cobb ap with off the shelf map is a cheap and easy way to go, but if you are serious look for a vf43, upgrade the exhaust, downpipe, swap the tmic for a larger one. everything can be done with used or new sti parts or aftermarket upgrades. again, even an etune would offer up lots of power over stock.
composite tgv's, avo inlet, then descend into upgrade madness.

I don't think turbo lag is much of an issue at all. Especially given the incredibly short 1st gear on these things. Even more so with a simple stage 2.

Not many front mount an FXT and for good reason, sort of un-necessary if you're not looking for 500whp.

BTW, selling my 08SportsXT 5MT.

Great looking car! If my budget was that high your car would be sold.

I guess the fmic is not what I need.
