Jul 10, 2006 · The STi has a larger VF39 turbo and a larger intercooler (been proven to be better than the WRX intercooler, just not THAT much better) The WRX is somewhere around 200WHP while the STi is about 240-250WHP. A WRX with the STi VF39, turbo back exhaust, STi intercooler, and a Cobb AP is rated at 285WHP. I beleive the exhaust is exactly the same ...

Feb 5, 2009 · 06 STI over a 06 WRX differences (est. price in quotes to add it later to a WRX, not including labor): - Bigger turbo ($300-$900 depending on used vs new) - Better engine (~$5k, maybe more) - Better brakes ($3-4K for a new Brembo BBK) - Stronger tranny ($2500 to $5000 depending on condition) - DCCD adjustability (add cost to the above)

Nov 17, 2005 · I was checking out COBB's website...and looked at 2006 stage 2 WRX: Acceleration Data: 0-60 mph : 4.6 seconds 1/4 mile : 13.4 @ 101.5 mph (average times based on our customer's results) Comes with AccessPort, and TBE. Could I make the 06 WRX even more powerful if I just sold the TBE and got an up/dp, or do all 3 of these work together?

Jul 21, 2006 · Well, I'm still new to the wrx and trying to find out some info on possible problems. I've been reading the forums and saw some comments about the tranny in the 06 2.5 to be not so great. My car is stock right now, I'm just wondering what …

Oct 24, 2005 · My 06 had a sharphid kit 6k low beams and they stayed on all the time. Didn't flicker or strobe beyond on startup. Otherwise always constant. I believe 07s had the DRLs voltage turned down because of complants from the 06 model year customers saying that the DRLs at night looked no different then the normal low beams.

Aug 15, 2009 · Also, is a 30% loss a more liberal or conservative estimate (for example the generic COBB stg2 map on their website claims an 06/07 wrx makes 224whp with just stage 2 upgrades)? I understand a 16g is at the smaller end, but going for the big16g or evoIII seems like it will supply a significant power upgrade over stage 2 that will still be ...

Oct 15, 2007 · As you have a 06 (2.5 liter) the street tire clas would be STU- no wheel limitations, but a 245 maximum width on AWD. 8.5" and even 9" width rims are used. Tire sizes of 245/40/17 or 235/40/17 for a WRX. ESP or SM has no rim restriction or tire restriction- so your talking wide rims and wide tires and R compounds.

Jan 4, 2010 · The OP has an '06 WRX which has an EJ255 2.5L. What no one has mentioned is the fact that a 16G is pretty small for the 2.5L and I would not go smaller than an EVO III 16G. Also, the fact that he should get an 8cm exhaust side b/c 7cm tends to creep on the 2.5L and the 8cm has better throttle response, top end, and is just better suited to the ...
