leave it stock. period.

if this is of ANY question with ANY car that you own, leave it stock. "whats the most power my car can handle" and "i want reliability" are so extremely contradictory.

5spd is weak. Will blow past 340whpish.

09 is also known for cracking ringlands fairly easy. I'd just leave it stock.

I'd say "Stage 2"....i.e downpipe, tune and a intake if you want the sound.

The 5 speed myth is crap. They've been used on the jdm cars since 1989 and the USDM was the first market to complain despite having the most underpowered WRX ever made.

Go stage 2 and call it a day.

Something that would help would be for you to post your:

WHP goal
Budget
Goals for the car (ie what it's going to be used for)

Anything can be reliable if you maintain and treat it good. If you are wanting to actually get into cars for real, then do your research, learn and read. Then mod, its fun. If you dont want to put in the real time which is in the books. Then stay stock. But honestly stock can be just as unreliable as modded. Granted modded has the make up to break down obviously more than a stock car.

Intake, header, up pipe, down pipe, catback, TGV deletes, turbo inlet, fuel pump, intercooler, external wastegate, EBCS, injectors. Pick any/all of these, some need to go together, some don't. Start with a down pipe and catback (if you have the stock not SPT catback). Catted or catless doesn't matter too much at your power levels. The most important thing is to make sure your tuner knows that you want it to be reliable while still upping the performance. You will sacrifice some power by doing that, but it'll be safer.

For reliability's sake, get a Killer B oil pickup. After inspecting mine, I'd recommend you do that sooner than later.

Edit: I wouldn't recommend going much past 320whp. Mine failed at 350whp.

That is was ever a glass tranny is a myth, what is not a myth is that they put the wider profile LGT gear set in in the 5speed from 2007 onward. You can still break it with half of the stock hp, as always it all come sown to the driver.

$1500, AP/Tune, Bilstein dampers with matched RCE springs. This get you close to 300whp and have a greatly increased handling.

If you want to farther from there, DP with a highflow Cat $450ish, (you do not want to use a catless DP with the 09+, they often develop boost creep problems that can not be tuned out) and 3in catback (another $450ish)to go with it. You will be able to tune this to 350ish whp.

Then a somewhat larger rear sway bar and stronger endlinks will help eliminate the last of the under steer and make the car pretty neutral, but most of the under steer will disappear with the better dampers and increased spring rate, I went with the 330lb/in RCE yellows and love them (as does my wife, they are not st all harsh with the better dampers)

Also a nice improvement is lighter a rims, the stockers are pigs, I swapped in RPF1's and saved 15lbs/corner of unsprung weight and put snow tires on the stockers for winter, cost me all of 300$ for the rims on craigslist.

I don't think you're coming near 300whp unless you have at least a downpipe "stage 2" type setup.

You could definitely get that professionally installed w/ quality parts and still be in your price range with some money to spare.

350whp is gonna be another matter entirely.

With what kind of reliability? I am so tired of seeing these posts about an intake and downpipe hitting 300 AWHP, because it is not the entire story. Read the posts on these forums from unibomber.. Supporting mods are your friend... Do the research on the forums before you do anything. It will really save yourself some time and frustration..

Stage 2 (dp and tune) is generally considered the safest route if you want extra power.

I wouldn't worry about your 5 speed. The 02-03 MY were the ones you really had to worry about shearing gears. Particularly on medium to large turbos (20g, gt3076, gt35, etc).

The vf52 certainly seems to be the best vf series turbo to date. Should get you close to 300whp, depending on dyno and fuel used.

Yeah. Really just a dp+tune is enough to hit 300whp on 93.

Find a used high flow catted downpipe and get your car protuned. If you are getting your downpipe professionally installed then you will probably be around the lower end of your budget with this setup. You may be able to find a used cat back and keep everything under your $1500 limit

The gain from the catback will be minimal compared to the cost. You might be better off considering ebcs, injectors and fuel pump (in addition to stage 2 setup). This could push you over budget.

Then again, if you find this stuff used or do the work yourself you could save a considerable amount of money.

If you curious what other people have put down with the vf52, check out Cobbs dyno database.
