I am sure this has been posted before and I am really looking for contemporary recommendations as these things can change from time to time.

I have a MY05 STi (JDM) and am looking for a really big power car, at least 450bhp, better still over 500bhp. I use the car every day to commute to work and do between 4 and 6 trackdays each year and so it must usable for both.

Does such a tune exist? I am looking for recommendations, who would you use, why and what is your experience?

Stop at 450 for TRUE everyday use on a Newage, anymore and you cant use it everyday IMO.

GeoffMM

well i am sure you must have realised that this could cost you up to 10k
the scoobyclinic sc450 is meant to be excellent value for money bu it does cost alot???

Tidgy

looking at about 15k prob cos of sc450, gearbox and clutch. but bear in mind its a off the shelf engine and has been under development for a long old time. Gaffer runs one in his 22b, only prob with it is it keeps killing rear tyres lol

Spooky Mulder

Wow! That was quick

My understanding is that my costs will be minimised as I will be able to use the 6sp box and that will take at least 500bhp.

Keep 'em coming - thanks

Only piece of advice I have is to go 2.5....Will make for a much better drivers car with it's extra low down grunt...

have a look at the MD321T turbo from Lateral Performance
will be good enough for 450 bhp with supporting mods and is a straight swap for your vf

Tidgy

o r didn't think of that lol, 10k for the engine on its own i think

Can the 6 speed really handle 500bhp

Tidgy

yeah mate, tis what gets swapped for when old gearbox can't take it on classics

Varboy

get a faster car? ie something capable of handling the power without stretching the envelope

The last time I was down at Roger Clark Motorsport there was a newage been shaken down for 400 plus BHP .....rotated turbo on a closed deck block (2.1 litre stroker if I recall) plus all the associated mods

If I had the money it's where I'd go ......

550 -600 is prob the level that stretches the envalope now

Tidgy

and that would cost ya 20k min lol

never used them myself cos everytime i've had a quote form them its been twice the price of anywhere else

Spooky Mulder

To get a car where 500+ is within the envelope would mean spending at least £50k plus chopping in my STi. That would get me a second hand 911 turbo or Lambo. Even then I would be spending money on top of the investment. I have driven classics with over 500bhp and the chassis was surprisingly with it. I am sure the new age is even better and has a much stronger drivetrain.

I reckon on spending up to £15k with the right people if I can find them. I am happy to travel for the right company and I am based in the north east.

mate of mine had a 500bhp classic, ate 911 turbos for brekfast lol

Gotta agree that the cost of going to RCMS is more than most places but I think you have to admit that they know their stuff and turn out some pretty nice "works of art"......just ask Bucky or WRX-Rich

Shaun

PS I'm running 400 odd BHP bugeye and don't think that much more could be used as a daily driver (which mine is)

Tidgy

yeah mate, as said not used them, but from what i hear they are veru good, but ver very expensive.

y pay twice as much for the same thing as a different company?, plenty of very good subaru specialists out there

GRIFF007

Shaun the Web is about to publish his development spec for above, and with the right fuel octane i believe the above figs should be realistic.

Not sure where all this £15k nonsense is coming from - should be plenty of change from £3or4k......

People do love talking up cost and difficulty in the UK...

Neilo

the 15k is coming from a completely rock solid engine build.

You cant guarantee that for 4k, the spec C for 2500 is based on the original engine, so nothing to swap other than ancillaries.

That counts for a lot.

Tidgy

umm, simple maths realy 400 is 50 less than 450 and 100 less than 500

and its simple mechanics, certain components can only take so much pressure/temps. go over that and they fail, go close to there limit and they fail after a short time.

not that hard to understand, any bunch of cowboys can just crank up the boost, dosn't mean engine will last

GRIFF007

Not sure Ian Litchfield & Powerstation would take kindly to being referred to as a 'bunch of cowboys!?' - I was merely putting the case forward that 400 / 400 for £2.5k might well be worth considering - when others are suggesting that each extra horsepower costs £250!!! - Yeah, I would much prefer 450 bhp - well worth the extra £12,500 for 50hp........NOT!

Just checking your math...it could be £12,500 for an extra 100bhp so only £125 each. Much cheaper than tuning a Porsche or similar

Daveo

Engine longevity and peace of mind?

The man's got 15k to spend on his engine - he'd be ill advised not to get a rock solid steel bottom end.

Good luck with the build.

MrRA

Big power and reliability comes at a cost, a big cost.

If I were considering something like this, Roger Clark Motorsport would be the place I'd go.

terzo282

i am in the same boat as i am going to do a similar engine build on my terzo. been talking to tsl motorsoprt to do the build. got a price list for various builds depending on what power output i want .

seen a couple of the big power engines in cars at there place might be worth a chat with the blokes there

ex-webby

Reliability is key in the modifying arena.

400bhp is possible on the standard Newage engine when spec'd and maintained correctly and should be as reliable as a standard motor. Obviously this is down to the parts used and of course the people fitting and mapping.

Personally, I have done about 10k miles in my car on the road and various competition events (ok... we are not talking endurance racing driven by Ayton Senna, but it is still worth noting), ranging from track racing (one event the car did over 60 laps in one day) and some drag racing. The car has been absolutely faultless.

Having a car that is used for track use is a different consideration than having it used on the road. Track use can be far more punishing and really can test the reliability of any setup (as can drag racing).

IMHO I would not go much further than 400bhp on a standard internal engine, a)because of what I want to use my car for I need the utmost reliability and b)because in essence you really need to go to the next level to get much more power above this.

From my current level, I am also looking at going to the next level over winter. I have a lot of decisions to make around this, but ultimately I need a package that has been proven for both power and reliability. Fortunately I have been in a position throughout the year that I have been able to closely monitor a couple of packages (one has been throughly tested in competition), so feel that this remit can be met without an issue.

Cost?!

Well it is'nt going to cost £5k , but as already said you pays for what you get.

the Dark side

If I was to return from the Dark side (unlikely) and I had that sort of money to spend on a conversion then I would only consider the people who are at the fore front of Subaru tuning. From memory of my Subaru days I seem to recall Roger Clark Motorsport were the boys, Andy Forest seems a popular guy these days not sure if he does engines though. I have also seen that Zen Performance and Powerstation seems to be doing quite well in the time attack series this year. They obviously know there stuff if there racing them, I dont think you'll go far wrong with any of these guys.

They are in a different league to the more commercial style tuners
You get what you pay for
