Have an 04 STI with PPP....have just purchased a full 3" turbo back (4.5" outlet on b/box) decat exhaust, have provisionally booked in for a ECU-TEK remap, have been told I'll probably end up with around 330bhp, but it seems a lot of money to spend out to me (£500+ for remap alone)for an extra 25 gg's more than what I'm already meant to have. So I was wondering what else (cost effective) way I might manage to end up with at least 350bhp, do I have to change the fuel pump/injectors? or the turbo!! I'm goooing dizzy. I used to have an APS cold air induction kit sitting in the wing of my classic but I've been told that an induction kit shouldn't be necessary as they can cause more harm than good!! Did I mention my dizzziiness (but what about a panel filter, are there any better than a standard STI's?)

Thanks for any help and info. I have a month to get my bits if any PANIC

swifty.....!

i'd change your panel filter to a green cotton one or in wing induction have this on mine with no problems and thats all you'l need to change with exhaust to get 350ish the mapper makes the difference but they all tend to under estimate figures just incase

the 25 extra does'nt tell the full story,you will have more power right along the rev range.it will come in sooner and hold longer,at some points you will see a lot more than 25 bhp"it's not just about peak power".if done by the right guy you will have a lot more useable car than the standard ppp car and it might even be a bit easier on fuel.
you should'nt need a fuel pump,there should have been one fitted along with the ppp.

The UK cars are more of a challenge to get to 350bhp than the JDM ones The Webmaster used to have an article on here where he talked through his mods (he's got a Spec C), up to about 380bhp apparently! From memory consisted of:

1. Decat exhaust.
2. Induction kit.
3. Uprated actuator.
4. Uprated fuel pump.
5. 3 port boost solenoid.
6. Remap.

Was thinking the right guys are in PROSPORT, would anyone recommend an Apexi 3 port boost controller or is the Apexi part a waste of money (leave it to the ECU), would just a 3 port boost controller on its own suffice/help at all?

MrRA

The 3 port boost solenoid will give the mapper finer control over the boost when mapping your car.

As regards the remap, you shouldn't look at it as £500 for 'just' an extra 25 horses. You'll probably see more than that in the mid-range which is where it will count. Torque will also take a big leap forward which will transform the driveability of the car no end. A remap isn't just about gaining more power. It is done to ensure that the fuelling, boost, ignition etc is correct at every stage and that your engine is running as sweet and as safe as possible.

Prosport is very good you wont get messed about just ask what you need to gain that sort of power (a jap spec is better for out and out power though ) and they will give you a straight answer

not far for me to go then.. just need the fuel pump/actuator.. for the 355-380ish jump... BUT the JDM cars do tune rather well... Mine was around the 320 mark once run in before any mods... Then the zorst,3 port and filter together with a map see 355 ish with around the same torque

As said above the 25 bhp is much more than just a figure. Mine was PPP'd before its remap and the difference was night and day tbh. Mid range was so improved and the car pulled to 7k with proper boost being held rather than dropping to 1bar at 5.3k as per the PPP map.

If you want pub figures to talk about you are not going to impress with a 25bhp gain. If you want a transformed car then it's for you

I have a re-maped ecu from a 02 sti that was 340......had fitted a full 3" de cat system......induction kit.......and im looking for £300 for the ecu.
The other parts are also for sale if you need any.

Once you've done the remap though, then you'll own the license. Subsequent maps should be circa £200.

You should've had the fuel pump upgraded as part of the PPP. If not, as some have found out, then: Walbro 255 Fuel Pump £80 -- It's recommended at the 330 level anyway.

An induction kit is not a bad thing if mapped in. But is not necessary for 330-350. If aiming to stay at that level then a Green/K&N panel filter will be fine. I have the APS on mine, but then i wanted more then 350.

350 might be a squeeze on the VF35 turbo you have now, unless you use tricks, like Methanol addictive (also mapped in).

If changing your turbo, then the skies the limit, whatever you want from your car/drive. 18g is popular, as it doesn't change the characteristics much of the current car, ie. spool time, but give plenty of kick and for longer. You'll see circa 360-370.

Other things to consider may be:

- Headers (ported) circa £200-400, including up-pipe.
- NGK7 plugs £50
- Subaru 3 port boost solenoid £120

Remap makes the biggest difference, maximises everything you put on to date iron out flat spots and improve driveablility.

I don't know how many tuners you have spoken to,but i tried all the big names when i bought my '54 plate STI PPP about mods/remaps etc,and they ALL said one thing.............the PPP figures are never accurate.

All the tuners i spoke to claimed that the "actual" PPP BHP figure can be as low as 260bhp,and is never higher than 290bhp (some way short of the 305 Subaru claim).

So if you look at those figures,and the tuners are claiming 330bhp minimum(which most do),you are getting at least 40bhp and maybe upto 70bhp depending on your car,and as said by others,the important thing is the improvement in torque,which jumps to 320-340lb ft.

PPP on newage cars is never as low as 260bhp. I think trading standard would be on the case otherwise!

paul2070

Like i stated,all the tuners i spoke to all said very similar things,260-290 max.

And that was TSL,Powerstation,Alan Jeffries(lowest) and Andy Forest(highest) .

Where's best to look for a TD05 18G? How much should I be looking at?

Nice one.

and some others...

You're lOOking at around £900-1000.

GazTheHat

You're not the only one. Best i heard, from an accurate RR was 290 max.
