Why 550 bhp ?
A torquey 2.5 will make a fine road car, even in standard form.
What are you doing with the car to need all that power ?
Just wondering.

New Age Sti with the VVT heads is a good start. A Chy (Pennine Subaru) 2.5 or 2.35 closed deck block should do the job using a good spooling up turbo.
Going 550 may point towards a rotated set up (more costly) so any reason why you want 550 and not say 500 which you could get away with standard position turbo?

you can still get 550 or there about on standard position ask dynamix or martyn J from engine tuner. they both run over 500 on a near enough standard position turbo. i think dynamix uses some jungle juice form morrison though lol

Once you have an idea of the dosh you want to put in this build then it is a case of approaching 2/3 tuning firms and seeing what options you are given with the end product/benefit. Think about the purpose and longevity of your build too.
Its all good saying this and that but if you cannot afford it then no point going down that road.
Also speak to a few members on here who are running at that power level i.e. Stevebt, Madhammer, Banny (experience on mods) and see what they've been through and if there are any tips they can give you.

Why a 5 speed ppg setup? Apart from you will be replacing it every other week when it breaks! The 6 speed is better for the job (just ask shaun, stevebt etc), and it won't be a cheap build (go to the technical area and read up about the scoobynet spec c) and I hope you understand the costs here, it won't be cheap for reliability at that level, start at 20k and add on from there!

If it's drag racing you are interested in I would rather aim for a xx time bracket and spec from there.
There are some 550bhp builds out there that just ain't all that quick.
Speak to someone like Andy.F or Zen who will have lots of experience in that field and will know what works and what doesn't.

Can be done several ways and it all depends on how you want it to drive and what your main purpose is. 2.1, 2.35, 2.5. Standard compression, high compression, NOS, race fuel, standard position and rotated mount turbo. The list is endless and so is the potential costs!!!
A 10sec newage is not a particulary cheap project.
It is not easy to acheive.

If you want a 10 second newage I think you need to spends lots of cash and it will have to be over 600bhp! Me and shaun have both found out that ours cars didn't make what we wanted but after a bit more time and more £££ we are both nearly where we want to be As for not many newages running big power I'm sure there is quite a few I loved my 2ltr engine when it was running around 480bhp as it was laggy till say 4000rpm then all hell broke loose as it jumped about 300bhp in 500rpm

The power is very easy to use on the road. Personally I don't see what all the fuss is about it being too much If I had a low boost setting I doubt I would ever use it. If you want to abuse the power though it can be a handfull at the wrong time on the road

Steve,
You can not use 500bhp in a scoob on the road effectively and certainly not easily. You will only use a proportion of that on the road. Unless you are referring to gay straightline stuff.
It is not all about power figures though..... response and lowdown driveability (for road use) are more important. A car with more lowdown response, sharpness and overall driveabilty will certainly be quicker on the road.
Either you need to get an engine set-up that is more responsive or you need to actually stop driving around in 1st gear, limited to 4000rpm.
Scoobzie,
I have multiple map settings and one of those is for low boost (1.45bar - over 485bhp at the fly). I very rarely have to use anything else for the road..... it is a waste of time in reality.

scoobzie,
That's a bit different from 550bhp!
Sounds like a good move though, powerwise.
stevebt,
Are you SERIOUSLY telling me that you USE all 500bhp on the road in your Scoob and you think it is no sweat and easy and you don't see what all the fuss is about?
If that is so, based on your engine build..... I suggest you need to get a better engine built.
You don't need any low boost..... your power is as flat as a witches tit till over 4000rpm. Some of us have real punch lowdown and rev past 8k you know.
