  1. Sweet cheers for clearing a few things up. How does this sound for a plan.

    Yellow top? injectors

    Tidy up the standard intercooler

    Walbro intank fuel pump

    Fuel pressure regulator

    Chip+tune

    300hp?

    Does anyone know much about how the wrc engines were set up?

    When boosting my car it does feel like it is laggy until around 4grand than it gets this big surge of boost, which i assumed was when the 5th injector kicked in? Maybe someone local who knows a thing or two about them wanted to come for a ride see what there thoughts are? It is certainly a s***e load quicker in 1st 2nd and 3rd than the missus v3 sti, but seems about the same after maybe 120kmh ish. But down low the missus v3 has a lot more response and seems to build boost alot quicker and smoother

    that pretty much sums up the v2 sti ra. remember its only running 380cc injectors, so compared to the v3 gear it simply runs out of fuel. but keep the revs up and it will dominate through the twistys :)

    there is a lot of conflicting info on the 5th injector. as i understand its purely for homologation reasons and is not driven at all by the 7K tune

    you can install a v3/4 manifold + v3/4 intercooler. v5/6 intercooler is possible with more work. there are a few issues in general to work around but its all doable if your willing

    cheap option for you now is to properly clean the v2 intercooler and straighten the fins. makes a difference aye

    if i was starting again i\'d refresh mine back to factory and enjoy it as is. quite a unique car and i miss it

    Sounds like a lot more work than first thought. As you said i would like to keep the 5th injector as it is quite a unique car.

    What supporting mods would you do to get the most out of the engine as is? You were saying they tend to run out of fuel due to the small injectors, if i was to upgrade the injectors, new fuel pump, tidy intercooler and possibly a link or chip+tune. Should this improve the performance. Not that it really needs it, but you know what its like once you get that bug ;D

    The missus wants to give me a race down the strip once our cars are both up to scratch so i need to make sure i dont loose ;D

    Also you said the 5th injector doesnt do bugger all, is there a way to get this working? Assuming it would make a difference?

  3. Not keen on chopping up things to make it fit, the wrc guys got away without running a front mount, so im sure i can :D The reason i want to go v3 intercooler is a read they flow alot better than the v2 one, not so much for cooling reasons as i dont plan on running massive power.

  4. When boosting my car it does feel like it is laggy until around 4grand than it gets this big surge of boost, which i assumed was when the 5th injector kicked in? Maybe someone local who knows a thing or two about them wanted to come for a ride see what there thoughts are? It is certainly a shite load quicker in 1st 2nd and 3rd than the missus v3 sti, but seems about the same after maybe 120kmh ish.

  5. What about the STI RA v2 gearboxes are they any different? Mine is starting to get a bit notchy so am considering rebuilding or a 6 speed conversion. As said above a 6 speed conversion should be relativly straight forward if i could retain all my rear diff ect? So all i would need would be box and auto drive shaft, is this correct?

  6. Now im sure this has probably been covered but ive done a search and can\'t find anything.

    What im wanting to know is, if i was to upgrade the intercooler and intake manifold from my factory V2 sti set up to say a V3/4 set up is there anything else i will have to change to make this all fit? Also should this be a good upgrade? I alos want to keep the 5th injector, can i still use this with the later manifold?

  7. Just wondering what peoples thoughts are in regards to wheel size and offset to suit a V2 wrx, im unsure on which size i should choose as i dont know what will fit right. I dont mind rolling the guards abit, but i dont want to have to worry about gaurd rub or running sillly camber. I wont it set up so it will handle the best, but trying to keep it looking good aswell.

    So what im wanting is something that will fill the guards nice but still be practical.

    These are the sizes i can choose from, im wanting 17s and obviously 5x100 stud pattern.
