  1. I've found most mechanics who say subarus are S*** or reliable are just S*** mechanics. It's either because they're scared of changing plugs which is an easy job or theyve seen loads of dead subarus but dont understand boost taps wound to 25psi kill engines. Either way theyre just basic part fitters much like panelbeaters are now panel fitters. You dont need to be shane t to know too much boost on a stock ecu is going to kill the engine.

    I've always felt I'd need a tune if I ran a CAI through the guard. Just because the greater amount of air coming in + colder air would surprise the ECU. I've got an Apexi AFC (can't remember specific model but can check) in my car and I'd be out of my depth if changing the intake would require any other changes.

     

    The v7 has an IAT in the the atm so the ecu can account for temp.

    Informative guide, I like the Turbosmart choice - Australasian company :) Out of curiosity, what boost are you running?

     

    Sold the car to another member @Furze

     

    On the 2l I ran 20psi max at one point and put around 1500km on it at 16-18ish. Pretty similar stats but far less km on the previous 2.5l which drove a lot nicer with it.

     

    Think it was tuned for 26psi on high boost at dtech.

     So there appears to be quite a few companies selling these..

    Google ..... 4 jecs 850cc side feed fuel injectors e85 global auto co....

    This is an australian company that sell them with a two year warranty..

    nz$ 243 + 32 freight..

    What you think ?

     

    Sounds good just make sure they are phase 1.

    did u find that you could only get the compressors on 2 coils close togeather? then you compressed them as much as possible then took the tophat off?

     

    Do that then when you rattle it theres way less load on the nut. Had that problem years ago when I had stock struts.

  6. I'd be inclined to think it would hit a wall in mid range circa 5k and torque would drop fast rather than taper off. 

     

    Mate had a 2.5 with vf36 and restrictor and it was really impressive down low. It worked well due to setup but on the road unrestricted very unimpressive.

  7. You have the perfect turbo to achieve your goals on a 2l. Its not a lot bigger than a vf which spool every time you sneeze. What power is it making and did you sort the issues it was having? 

     

    Putting a bigger turbo on a bigger engine is going to put you in the same place for more money.

    The p25 is good for around another 10wkw from what I've seen on same dynos with similar setups factory heads, same fuel, boost, mods etc.

     

    That's on 2l and regardless which housing its the same turbine wheel which is more the restriction.

    That's on 2l and regardless which housing its the same turbine wheel which is more the restriction. On second thought being a murch hybrid it may have a clipped turbine which would help your cause. Still reckon its to small for anything over a 2l tho.

    Yea that's the one. By similar do you think the 2l will be better in peak numbers or will it be pretty even? I was leaning toward the 257 for better drivability and torque down low as most of my driving is around town. 

     

    I think it would have less potential for power/torque than the 2l. Would be a storm down low but that'd be about it. No idea how the tiptronic would affect that.

    How is the torque in low rpm (before boost kicks in) with stroked ej207 vs standard ej207? I'm trying to decide what motor to replace my dying motor with in an auto bp5. Has slightly bigger turbo and the trans shifts too low when cruzing to keep it in its powerband so drives like crap  unless I manual shift it. I'm leaning toward the 257 but open to options. Will also be using ej20x/y heads and aiming toward the 230 to 250kw mark. Cheers

     

    Is this the vf murch hybrid?

     

    If it is, more displacement will probably choke it and cause you to taper boost in the top end resulting in similar power numbers to a 2l with vf.

  11. You need to at least drive it in and out of the garage to settle it. Generally when you drop the car your tyres sit so they give positive camber which makes it look higher. 

     

    With my bh5 the teks were sitting outside the guards until I went up and down the drive then they sat inside the guard.

    Yes .Keith stewart will be tuning ..

    Have got to fit stock headers and modify turbo mount to sit turbo level..

    Then modify down pipe to suit..

    Then tune for 300whp..

    Run it for a while like that and then rebuild engine and run in..

    Followed by touchup tune with maybe another 20-30 whp..

    Sounds easy...........................

    But its not.

     

     

    Just run it twisted or fitment issues?

     

    Which spec did you end up with?
