    Is 124 kw not enough? I would leave any engine mods alone. It is superb as standard. Maybe add a k and n air filter. Changing the wheels is a personal choice. I quite like the standard "cyclone" alloys, but I suppose you can go to 16 or 17 inch wheels with a lower profile tyre. The excellent ride would be compromised, though.

    My plan of attack would be:

    Quaife LSD
    Quality after market ECU
    Inlet cam

    Learn to drive the thing, I mean really drive it. The car is more than enough. It will never be fastest in straight line (V6 commy exec will get you), but once the corners come along you will have tons of fun.
    LSD will definately transform the car, whether for good I am not sure. It can become a tad of a pig wanting to understeer until you accelerate midcorner. I never experienced much wheelspin in my non-LSD 6 so unless you wish to race it I might want to stay away from the LSD (ask GTI124 for his view on LSD in GTI6).

    Great tyres, new plugs, new air filter, clean the carby buildup in the TB and experiment with handling through either a advanced driver course or at Wakefield.
    I'd stay away from engine mods till you really think you found the car's limit.
    BTW. Friend of mine tried to chip his '99 6 with powerchip and it failed. The stock ECU wouldnt allow mods of fuelling tables.

    I'd personally use Haltech, Autronic or Motec.

    The inlet cam is the thing that most significantly determines the power range on a normally aspirated engine. As it's easy to access and simple to change on an XU10 engine, it's the next logical step after you've got a programmable ECU. The XU10J4RS already has enough compression and head flow, so it's the only way you'll start to make a significant increase in power. The exhaust cam doesn't need to be changed unless you're aiming at huge hp increases.

    But as Tekkie said..............

    Yes, I still have the P6000s on mine and they are rubbish at getting the power down onto the road. Will be graduating to another brand in the coming months so stay tuned!!

    Peter, do you think the inlet cam would result in any loss of power in the low and midrange?

    Tekkie, my previous car had a clutch plate type lsd which showed some initial understeer until power was applied like you said, but the quaife I've got on the gti6 feels like it makes no difference on turn in and only really starts to cut in when serious power is put down. But like you said, it's not worth the money on such a well balanced road car like the gti6 unless it's doing a lot of track work. I'll be looking to get a 205 sometime to be used for mostly track work and the lsd will be taken out of the '6 and put into that.
    Take the long way home....

    while on the subject, my GTi-6 needs some new tyres.

    what can ppl recommend with a good balance of performance and value, bearing in mind that i only need them for standard road use?

    after 2 sets of p6000's... which i found.. did not live up to my expectations...

    researched wit my cuz (ex-euro mechanic) over a few months and we decided upon getting the..

    ...michelin potenza's... its dark outside so will give u more info tomorrow. BUT i can say.. the grip, the control, the cornering given by the new michelin's is absolutely amazing... it puts the p6000s to shame... had them for over 6months now.. and still going strong

    Think you mean preceda's, yes?

    Jack those puppies to 38psi to really feel the grip (Note: Some ride degradation may occur).

    Go to goodyear and Buy GT radials 195/50 profile champiros $135 only, grips like stink ,the drop in profile sharps the handling and makes your speedo 7% optomistic which is a GOOD thing. I have heard that 16" or 17 " really gets the handling going but at what price and what cost for tyres.
    I chew up the Champiros in 30,000k but at that price who cares.

    James, you might want to check some other's experiences about that, as other people who've tried putting 195/50/R15's on their gti6 said that it made the car ride and handle worse and they've since gone back to the usual 195/55/R15's.
