Question Further modding a STI with PPP to 350BHP

What is required to change \ add to get the performance figures from 305BHP which is the PPP figures to something near 350bhp...(MY03)

Is this a safe level or not recommended?


Any help appriciated...

should get to 350 without problems, matesr unning 420 on his.

first off strip the whole ppp and sell it on and replace the ecu with a none ppp'd one.

should think headers, full decat, cold air induction, remap for the new ecu and you're not gonna be far off.

Why would you want to strip the ppp? Take a look here https://www.scoobynet.com/scoobynet-...llingroad.html

just done this to mine exactly the same car, ported/wrapped headers , k&n panel filter, colder grade plugs, decat d/p achieved 331/343 a real treat to drive. Dont worry about the induction unless your going to be aiming for 400ish later on. My next step now is 321h turbo 660injectors and induction should be around the 400mk then!!!!!!1

cos you can get more money than a standard ecu for it, and all you need is a normal ecu to map.

plus you'll need to decat it to get that high, which stripps off the rest of the ppp anyway

I think he means that it's the same price to ecutek an ecu with a prodrive map as the standard map, so it might be worth selling on the "prodrive'd" ecu and get a standard one instead. One problem with this is that the keys have to be re-programmed by the dealer when you change the ECU, as the car wont start otherwise. Not sure how much the price difference would be?

If you could get decent money for the prodrive pack on it's own, it might be worth the hassle (fuelpump, rear exhaust silencer, ppp downpipe, ecu + possibly other bits).

Just get your ppp's scoob remapped with no extra bits at all, keeping the ecu and everything.
340hp will be yours.

Exactly. That's what mine is giving after a re-map and using the PPPexhaust. Any worthwhile increases from now on, require hardware changes and much wonga! (As I am about to find out next week )

so does this mean i spent out on wrapped/ported headers and matched up, decat 3" d/p air filte and plugs for 3 extra bhp, as mine was done with this lot on it and made 343bhp allowing a 23% loss.

Nope m8 there's no way in hell you'd get 340 Bhp just from a remap. Mines on 286 Bhp at the wheels which is with the uprated fuel pump, (part of the PPP) Colcder firing Iridium plugs, Exhaust, ported headers and downpipe & APS CAI.

With 23% Transmission loss mine works out at 351 Bhp but if work on 18% (more realistic) it works out at 337 Bhp

managed 340/330 from a standard ppp car.. standard ppp exhaust etc
https://www.scoobynet.com/scoobynet-...llingroad.html

however you should get more under the graph with decat, tubular headers etc.. but peak won't change much

From the posts I have read and Simon backs it up, 330-340hp seems normal for a stippp remap only.

A solid 325bhp is achievable with the PPP parts going on Fozzy's MY03STi

Working on the 16% above WHP, some might report this as a higher BHP and use a higher %, matters not as headline power won't reflect the good work done under the graph as Simon says

Depends on who did the re-map?
More importantly, is the area under the graph, not a peaky curve or the final little spike that gives a few more (unusable) hp

How much am i looking at cost wise for the PPP to near 350bhp conversion...?

I noticed TSL to a PPP to 333 conversion for £850+Vat...i am guessing most of the cost there is going towards the map..?

The TSL Converstion quotes; includes a filter and de-res centre. Could be argued that both are unecessary. This leaves an expensive and optimistic map for 350?

The STi panel filter is easy to pop in yourself at around the £45 mark. Unless you want more noise I would leave the centre alone. This leaves the map for which you have a huge choice, my personal choice would be mocom racing.

As far as the 350 is concerned I don't think the conversion would give a genuine 350, TSL is only 333hp, perhaps on some rollers it might, but I think 330 is a safer and less expensive converstion target.

Cost wise probably about £500 -£600 from Mocoms if you upgraded your plugs too

To put you mind at rest, I went from 305 to 340 (339/312) if you want to be pick. I did this will little hassle. Remap and decat center section which no one has mentioned When I spoke to Powerstation being a Good source they said that they wouldn't want to take a UK STI over 350. loads do..... this all cost me a bit of change out £750.00

Had enough now of the toys and just want a Spec C type RA
