HI, just looking for some advice really, I have an 02 bug with a prodrive pack, as done by the previous owner.

So I was thinking of putting a decat downpipe on and a decat centre section with a KN panel filter.

Will this add to my bhp? and will I need a remap or could I reset the ecu??

Any info would be great

remap would be required to benefit from the mods, if you already have the ppp then wont your car already be fitted with a sports cat downpipe?

i decatted my bug and fitted the sti panel filter and walbro fuel pump (for piece of mind) then got it ecutek remapped.. it went from 215 bhp upto 275bhp

WRX?

If so, add a Walbro 255 pump, fresh plugs to your mentioned mods, then get it ECUTek mapped, and you should have c.280bhp and similar torque - plus better, crisper throttle response/driveability throughout the rev range...

Sell your PPP ECU first (get a bit of cash for it) and replace with a std 02 WRX ECU (as it'll get overwritten anyway with the new, better, bespoke map).

As above, stage 1 would be de/sports cat fuel pump and remap - see about 270-280

Stage 2 - injectors & Turbo (plus sti TMIC) - see up to 350 safely on the OE internals and Gear Box.

Much over 350 and you need to be very gentle/lucky not to break the box.

Didn't ppp come with a sport cat in the dp and the midcat removed already??!

WRX, yes.

To tell you the truth I dont have a clue if it does have a decat exhaust or what, the guy who I got it from was under the impression it was just the back box, ecu and a small piece of pipe to the turbo, 100mm long approx.

I will have to have a look at the rest of the exhaust, confused now!

Thanks all

I'm sure the PPP package was at least the back box, silicone/metal TMIC Y-pipe and tweaked ECU.

I'm like you though - don't know about the centre section and/or sports/cat downpipe? I expect that at least one of them was chaged for the PPP kit, as otherwise prob wouldn't get the PPP quoted power otherwise(??)... (matt and dan are no doubt correct )

94beaver

ok cool, I will have to try and find out what one I have got then, and possible get the one I don't have!

So then I could get a walbro pump ( where can I get one?) new plugs and a ecutek remap, sorted?

PPP for our car has the IC hose, third cat delete, back box and the ecu mod. STI gets the sports cat down pipe

94beaver

Ok. Is worth while doing the down pipe then?

Beaver, you said the previous owner had fitted the ppp kit. Did he do it himself or have the kit fitted by subaru? If you can't answer these fully then i'd suggest doing some driveway detective work and have a look at the exhaust system yourself. If you have the ppp downpipe then it will have a sport cat in it. There should be a part number on there you can get and find out which type you have. You will be able to (if you are handy with spanners) remove the mid pipe cat (after the down pipe) and have a look to see if the cat is in there.
Basically you want...
1. A down pipe that has a sport cat (or decat if you aren't worried about the law)
2. Decat the mid pipe. (it won't make the car illegal if you have a sport cat)
3. Fit a good new pannel filter (k&n, green) Don't go for connical filters as they sap power and can ruin the airmass meter (and subsequently the engine!!)
4. You should already have the blue y pipe and intercooler to throttle pipe.
5. Fit a walbro fuel pump (for piece of mind and to prevent any lean fueling issues)
6. Have the ECU ECUTEC mapped (or if a ppp ecu is fitted- replace that with a standard ecu and have it mapped)
To be honest decatting the uppipe is an expensive job- I'm going to do it when i replace my turbo as it makes the job easier and is better to do both at once.
Hope this helps you achieve what you're looking for i'd say about 275bhp approx.
Matt.

Defo do the downpipe - (other than a turbo/injector change, obviously), it's the next most influential thing to liberate power/torque after a remap!

BTW, I forgot to mention, that I think part of the PPP packge also included an uprated fuel pump that's similar, if not identical, to the Walbro i.e. a flow rate of anything up to 255l/h.

But whilst you can't see it - and have only got the previous owner's word about the full PPP - you don't know if it's fitted! Therefore, I'd just fit a Walbro anyway, and if you do already have a PPP pump, just sell it for a bit of cash (if you can)...

wrx ppp did not have a pump change, just the intercooler hose 3rd cat delete pipe backbox and a ppp map added to the ecu, or on bugeyes they had a board added inside the ecu and a restrictor pill change as well I believe. The bugeyes were only 245bhp on ppp whereas blobeyes were 261bhp.

Not all 02 wrx's have the piggyback gems board as part of the PPP. Depends when the PPP was fitted. The certificate should say the date.

Full decat, walbro 255 pump (from lateral performance), NGK 7 plugs and a remap and you should see a lively 280 bhp ish. I would put on a 3 port boost solenoid too as the actuator is pretty weak on that model and will help get some proper boost and torque.

Cheers for making that clear... (for the OP's benefit lol)

94beaver

Thanks to everyone, the advice is sweet!!

I what to get rid of all the cats really, my plan is to wait until the end of next month, when my MOT is due, the give the car some tlc...lol

This also give me time, hopefully to get the other few bits and pieces (walbro pump - 3 port boost solenoid, where can i get this??)

Whats so special about an ECUTEC remap??....any ideas on a price?

Kind regards

Walbro you can obtain from most of the specialists who routinely advertise on here.

Early 3-ports can be had on here in classifieds or ebay for around £30 max..

Nothing 'special' as such about ECUTek - it's just that your car's ECU is geared up for a mapper to map it via the ECUTek software etc.

The software is not a public domain piece of software, and I believe ECUTek vet any would-be mapper who wishes to apply for a licence to be able to use it. That's good in that respect, as you're unlikely to get a 'practicing' amateur's (possibly dangerous!) map on it!

ECUTek 1st map is around £650 - but this includes a "first map licence fee". Subsequent full maps would be around £300-350, as the fee will have been paid. Minor map "tweaks" are at mapper's discretion, but £150+ seems to be a typical price...

94beaver

Great thanks, will look into that, £650 for an ecutek
There must be another way? I can't afford that just yet.

iTrader: (1)

There is open source mapping. Similar to Ecuteck but no license so somewhat cheaper.

dynamix

iTrader: (3)

There is another way. I charge £350 for a full custom remap.

94beaver

Still, a fat chunk of money tho!!

Hows comes you can do it cheaper? How long have you been mapping cars?

just what I wanted to hear!

I presume it's a wrx?
Up pipe, down pipe, walbro fuel pump should see 280bhp (factory PPP is circa 260, as mentioned by daz maybe 245bhp on bug)

I would recommend get a turbo and injectors at the same time. I done the staged approach on my 2005 wrx and in the end put a bigger turbo and injectors, which ultimately costs more for mapping and fitting.

Advice - up pipe, down pipe, walbro pump, turbo and injectors at the same time, then re-map. You should see 320bhp+ depending on turbo.

94beaver

Yes. WRX

I just dont have that kinda cash at the moment, to do the turbo and injectors...as much as i would love too!!

The up pipe is difficult to change, so someone said. So I might do the downpipe and or centre section if it has not been done, a walbro pump, 3 port boost solenoid, I think thats it

Shailan

iTrader: (1)

I bought my turbo for £215, a td05. Injectors for £180, 550's from Zen.

to benefit from a bigger turbo you would definately need to change the up pipe and down pipe.

There are quite a few td05's going, also ask fiestaboy for fitting prices.

good luck.

94beaver

Christ, really? Second hand I take it. I thought they was alot more. I do hear what your saying.

So you reckon wait and do the whole lot in one hit?

Shailan

iTrader: (1)

yes I bought a td05 second hand from a scoobynetter.

Just to save yourself the additional £300 for the re-map, if you can do it in one go. If I could go back I would have done that and saved myself £300 + less fitting costs due to doing in one go.

Hope that helps.

Where are you based?
