FWIW on my first scooby 53WRX I bought the PPP and it was disapointing from a performance perspective. I then did what I should have done originally which is sports cat remap.

Best advice is to drive a PPP car from a dealer, least they can do if you are going to spend £1700 ! then jump straight back in yours and see what if feels like.

I do this in my cars. Some days I jump in the SpecD and I swear it's only as fast as my Wagon. Then I jump in the wagon and it feels like someone nicked my turbo !

I think you get use to the power.
the first few months of getting mine I was like sh*t this must be faster than a porsche
funny now i'm not to sure

£700 for the parts for ppp incuding remap shows what a rip off ppp is! you could upgrade your turbo and be the right side of 350bhp with the other 1k which will be compleatly fine with your car, and would mean you could stay with an unmodified classic sti if there are any left out there.

Have heard that the consumption goes down due to the increased torque available, amongst other things.

For piece of mind, PPP. It's a useful upgrade, particularly for torque on a 2.5. Warranty extension is about £550 a year I think.

For better performance/value, couple of exhaust bits and a trusted mapper.

Just comes down to what you feel happiest with.

I had/have a similar dilemma.

My current train of thought is leave it as it is with the freer flowing exhaust (for noise and placebo more power effect!), then aftermarket map and downpipe sports cat when the warranty runs out.

IMO £500 p.a. to extend the warranty is a lot of money and I'd rather take the gamble. Besides, warranties are like insurance and the garage will always try to find a way to wriggle out of honouring the policy.

I'm sure I read that some of the tuning companies offer a warranty on their work, though that's an entirely different topic altogether.

Best money I spent was driver training. The result was me and my car being far quicker than a 40bhp boost.....

You could buy a classic for the cost of the PPP

MrMajic

Thanks all, some good advice there, food for thought. I like the idea of driving a PPP from the dealers - hadn't thought of that. I'll give them a call...

53WRX, where can I get the Decat rear centre pipe for a 2.5 WRX?

I owned a 2003 STI without PPP for two years, then got my current 2005 STI with PPP, which I've had for 18 months. I wouldn't have paid £1700 for it to be fitted, but buying a car second hand with it already fitted, the difference in price is much less.

I definitely get better fuel consumption, and there is less lag. I've never felt that the PPP car feels much different in power terms to the non-PPP car, and in a way I miss the feeling of the car taking off violently when the turbo kicked in.

The PPP backbox does sound better than the standard STI one, but is still a bit quiet for many people (myself included). I ended up changing both the backbox and the centre pipe (for a deresonated one), so the only PPP bits left on the car are the fuel pump and the remap.

Does this bolt on straight to the rest of the exhaust system (OE one)?
I was also thinking of the PPP but since the car is not a UK one and I will loose the warranty anyway I plan on doing the following:

- walbro fuel pump
- sti panel filter
- decat rear centre pipe
- Ecutek remap

I can also keep the Genome backbox that I have (I would have a redundant backbox if I went the PPP route)

From what I have seen though is that the PPP has more emphasis on driveability (more torque available at lower rpm) whereas from the results of other mappers I have seen max torque is usually achieved at higher rom which is nto what I want.

yep and in six months you'll be able to buy a hawk eye sti for not much more

Mocom Racing Road Remap stats for you quoted at the wheels because all else is speculation

H&S Sportscat Downpipe
Rear Centre Cat removed
H&S De-res Centre Pipe
STi Backbox
STi panel filter
Denso Iridium spark plugs
Walbro Fuel Pump

Before:

Maximum Wheel Power: 240.0 BHP @ 5678 RPM
Maximum Wheel Torque: 249.1 LbFt @ 4501 RPM

After:

Maximum Wheel Power: 288.1 BHP @ 5354 RPM
Maximum Wheel Torque: 322.8 LbFt @ 3998 RPM

I asked for the power band to moved lower down the rev range.

• Standard STi power (BHP) is now available at 3600rpm and still climbing instead of 5678rpm and falling.
• Standard STi torque (FtLbs) is now available at 2700rpm and still climbing instead of 4501 and falling.

Rear centre decat pipe is a direct replacement as long as it is for the MY06. MY05's are a shorter pipe.

Nice one, exactly what I am looking for.
How many miles have you done since the remap and how many has your SpecD done in total?
Have you had any problems?
Cheers!

How many miles have you done since the remap and how many has your SpecD done in total? 2000/9000
Have you had any problems? Overboost - induces fuel cut requiring slight adjustment in the wastegate table. Common problem on the 2.5 ECU set up. Easily rectified and has not been a problem since it occurred Only happens on hard acceleration from 4th to hard again in 5th. 4.5 -5k revs. This equates to 125mph in 5th gear testing and would only occur if you were seriously looking to lose your license. But its easily fixed anyway

On your car I doubt you would see any overboost as you are keeping the std Downpipe like the PPP model. Even so your mapper will know what he's doing. Mapping this time of year in the cold will throw it up if it's going to happen

Hi all

I've just been checking with Tesco as to what effect this would have on my insurance

The info on the Subaru site for an MY06 STI shows 3 things changed (ECU, exhaust, fuel pump), but I recall seeing that the red (?turbo something) pipes (sorry I'm no mechanic) are changed for blue ones, which I presume are somehow uprated.

Does anyone know if this is a fourth item that is undertaken, or if it' just the three I've listed?

Thanks

not 100% but i think the sti has the hose already as standard

Thanks, I'm sure someone'll be along to confirm.

If I was in the same predicament as you, I'd have to say that the geometry changes and driver tuition (trackdays have this available) will tide you over until the warranty expires then you are free to get a bespoke remap, exhaust and a few handling upgrades which will then give you far better VFM than a PPP

MrMajic

Thanks

MrMajic

Thanks, it's the fact that PPP is Subaru "approved" that attracts me to it. I like to keep cars standard. I realsise that not many others have the same philosophy, and that it's not the best VFH route.

I will do a track day, but have have a reasonable amount of advanced training (albeit mostly motorcycle based) but when driving on the road, the principals are the same.

PPP also more attractive when you sell your car.
Prodrive are well known and a re map not so well known.
So you could re coup some of the money you paid out in the first place or make your car more saleable because 2nd hand market can be a slow.

I fitted PPP to my Classic when I had it, was worth it,car was so much more flexible to drive,with better torque and felt smoother and better at higher revs too.

Evo rated it for both the 2.0L turbo and 2.5L turbo.

(For the 2.0L turbo Evo tend to rate the RB5 (PPP)as a classic car , when a normal 2.0L turbo was identically the same with PPP!!! and not so highly rated!)

In the instructions with my PPP it stated that super unleaded was only to be used,but the car could cope with normal unleaded but at reduced performance,so maybe the PPP ecu has a safe guard.
A remap would probably not have this safe guard if car run on inferior petrol if the car mapped on Superunleaded only!??

PS I got all my PPP 2nd hand for a few hundred quid and fitted it myself from an identical donor car, so saved a fortune!!

i never buy this resale value malarky, if people are that bothered about it don't buy one, your not gonna get that back and there is just as many with ppp for sale, so you could spend half the money of the ppp for more power and better fuel economy(saving more). ppp is good for warranty only imo. plus you could tell the buyer its an official ppp car like you did
