apexjapan Posted November 17, 2011 Share Posted November 17, 2011 Dyno's, in general, are just a measurement device. 5 different dyno's, even from the same maker, and you'll get 5 different numbers. So the most important thing isn't your final number - it's your starting number and the increase from there. That's the only yardstick that's constant. Keep in mind that 0-60 numbers are somewhat artificial - and I'm saying this as a former member of the press that likes to put those numbers out. The numbers put out by magazines are ideal conditions, ideal driver, best number out of who knows how many launches. And they will launch it like they hate it, because they can - they don't own or have to pay for the car. When I was involved in press launches where we got to drive new sti's around the track all damned day long, yes, I hit 155mph on the straights. I abused the hell out of the cars, and to this day I'm still guilt free. Last - this is really a low-to-mid range kit. As in, the biggest improvements are seen from 1500rpm to 5000rpm. It's tremendously driveable as opposed to a quarter mile beast. It's the 250hp V8 vs. 250hp 2-liter Honda argument, basically.

TinKnocker38 Posted November 19, 2011 Share Posted November 19, 2011 i want to turn up the boost in the future what should be done next internal wise? Link to comment Share on other sites More sharing options...
scottyjneilson Posted November 20, 2011 Share Posted November 20, 2011 Now all we need is someone to be the test dummy for this on an auto... haha. I know it will not be as fast but hey it would be a fun project... Link to comment Share on other sites More sharing options...
1stick3pedals Posted November 20, 2011 Author Share Posted November 20, 2011 i want to turn up the boost in the future what should be done next internal wise? I wasn't considering doing that for a couple years. I'm planning on pulling the motor and talking to a subie engine specialist. Probably do full internals and 255/257 bottom end. If you don't lower the compression it's going to be costly to turn up boost without damaging something. Unless you just swap in a WRX/STi motor.

I would also say if possible find a blown EJ253 (spun bearing or similar) and have it rebuilt on the side so all you have to do is swap accessories and drop that back in, unless down time isn't a issue.

GEE-OTTO Posted November 21, 2011 Share Posted November 21, 2011 i want to turn up the boost in the future what should be done next internal wise? Rebuild it with Stock LGT or WRX pistons and rods really that is all the crank is the same for the N/A and Turbo Subaru's. The pistons are cast so a good set of forged will provide long life and detonation protection. A larger oil pump 10 or 11mm will ensure its lubed properly under the higher loads.

1stick3pedals Posted November 22, 2011 Author Share Posted November 22, 2011 Hi guys just stopping in to say I am still alive Nice haha, how's the car doing? I'm up to 6000 miles by the end of the week. I'm sure you're much further since your last update was 8000 a while ago haha. Link to comment Share on other sites More sharing options...
Ryouske Posted November 24, 2011 Share Posted November 24, 2011 Yeah I'm not ure how far in I am. Car isn't doing well, we're having issues tuning it. Seems as though my fuel system is either old or something else. Seems as though my car has a return less style system and whenever the boost is turned up the car leans out. Working with AJW to figure something out. Link to comment Share on other sites More sharing options...

dubunderpar Posted November 25, 2011 Share Posted November 25, 2011 So is there an AVO kit on a 4eat yet? I know that everyone says, what's the point.... but the point is that a MT is not going to fly with the boss lady, and plus I love my wagon and don't really want to find another one. Especially since I doubt I will find one as clean and still have no payment. Link to comment Share on other sites More sharing options...

Especially since I doubt I will find one as clean and still have no payment. I don't believe so. From what I've heard and read I'm not too sure how much the 4eat can handle. I know the 5eats can handle quite a bit in the GTs, but as for the 4eat, who knows Link to comment Share on other sites More sharing options...
N.sane Posted November 26, 2011 Share Posted November 26, 2011 If I'm not mistaken, it's the same 4EAT found in the WRX's. If that's the case, it should handle this kit without problems. Add a Tru-Cool transmission cooler just to be safe, it's cheap insurance for $50. Link to comment Share on other sites More sharing options...

GEE-OTTO So are you saying lower the piston compression ? isnt that really the only major thing that separates the 2.5 from the GT anyways? if he tosses in wrx or gt pistons then wouldn't he basically have himself a gt with the double digit boost he could run with a lower compression engine ? I understand there are probably other mods that need to be done if anyone were to do this but wouldn't this be a better solution in the first place rather then a low boost turbo or entire engine swap. I would imagine it would be quite the project but a set of new low compression pistons that are rated 8.0:1 are only 649 a piece. is this correct ?

Ryouske Posted November 27, 2011 Share Posted November 27, 2011 Oh, that's not good. What injectors and fuel pump did you upgrade to? I've got injectors from a 02 bug eye and a lgt fuel pump, what did you use? Link to comment Share on other sites More sharing options...
GEE-OTTO Posted November 28, 2011 Share Posted November 28, 2011 I've got injectors from a 02 bug eye and a lgt fuel pump, what did you use? Yeah i would bet your injectors are maxed out since they are from the EJ205 what did they flow on the bench or did you have them bench tested? I would look for a set of WRX/LGT Ej255 injectors and see if that helps your situation Link to comment Share on other sites More sharing options...

Well yes, ideally one would build a low CR Ej253 to run with this kit. Lower CR pistons and rods aren't very expensive. The most ideal scenario would be a person that had a spare shortblock built to lower CR spec 8.5:1 or even 9.0:1 and were able to swap it in during the install. This way they could go up in boost at will. However running low boost is MORE than enough for many of the people that buy the kit, hell 6psi nets 200 at the wheel going from 122 to 200 at the wheel would make most happy. Point being the lower boost application is very viable for this platform and I guess that is why people wont go lower CR until they blow their current motor or find a cheap SB to rebuild Link to comment Share on other sites More sharing options...
Ryouske Posted November 28, 2011 Share Posted November 28, 2011 I have clue, but I know they were an 02 bugeye wrx not sure if that made a difference or not. Link to comment Share on other sites More sharing options...
1stick3pedals Posted November 28, 2011 Author Share Posted November 28, 2011 I've got injectors from a 02 bug eye and a lgt fuel pump, what did you use? I'm running the DW 650cc injectors and the LGT fuel pump. Looked it up quick, stock WRX injectors are 420cc. They might be maxed out or running close to max efficiency.

Short blocks are like 3k and I would suspect you would really have to love your 2.5 dearly to dump the cost of a high mileage gt just to get to where a gt would get with a tune...

GEE-OTTO Posted December 5, 2011 Share Posted December 5, 2011 Yeah like say you love your particular 2.5i and you NEVER want to part with it then that would be a optimal scenario. Like me bought mine new with 2 miles and i dont think ill ever part with you know the longer you own a car the more it pays you back so i could total see that happening Link to comment Share on other sites More sharing options...

Like me bought mine new with 2 miles and i dont think ill ever part with you know the longer you own a car the more it pays you back so i could total see that happening I love my car, would never trade her for anything. Hence buying the turbo kit, now I have a basis for more power in the future. Even though future power requires engine modifications, but I'm looking forward to that This car has never given me any issues after 34,000, she's a keeper! im think of doing this to my 2.5i how do you like it? big diffrence? With a 75 whp increase, I love it. The difference is big even though I don't fully take advantage of it like I should. But it's nice never having to leave 5th on the highway, and getting up to speed is a piece of cake with the level torque curve. It's a great upgrade for the 2.5i even if you don't always use it, it's in your back pocket for when you need it. Link to comment Share on other sites More sharing options...

1stick3pedals Posted December 13, 2011 Author Share Posted December 13, 2011 Got another MPG update. Had a lot of highway miles this time around, and stayed pretty tame with the throttle. So mixed (mainly highway, aggressive on the throttle every so often) is usually ~ 24-25mpg Last tank mainly highway ~ 26.55mpg I can live with that Link to comment Share on other sites More sharing options...
