As above TMIC not required if sticking to a TD04.

RR is not as harsh as it seems, it just sounds like it as you are stood by the car (not in it).
In reality its a flat out acceleration to almost the rev limit, nothing 'new' in that for most Scooby drivers...

Don't worry if the map time is a lot quicker than previously mentioned, many mappers have suitable maps already saved for 'typically' modded cars which is the bracket you fall in to. So they load a map on and they are 80% there. Some fine tuning and you are done. If your car had major changes it would take longer.

Mapping can have issues. Usually due to pre-existing conditions or sh#t bolt on bits.
Mine was fine on the rollers, but split a top hose later on probably just 'old' but highlighted by a bit more movement in the engine bay (extra torque?), which makes sense if you think about it. Then a split in the bottom rad mounting, which was rusty and probably failed due to the same reason...

All being good you'll be looking at 285bhp with similar torque figures. In the real world it's like night and day. The car is not just quicker, but smoother, turbo kicks in earlier... You'll love it, so enjoy..

 

Mine went from 231bhp to 286bhp on Roger Clarks rollers, at 4000 rpm it made 100bhp more, much better.

 

Thanks for a great reply, that has explained it a bit more to me and I feel more comfortable with the whole thing now. Many thanks!

 

Mine went with JGM from a ppp 265 to around 320 with a TDO5 and pump & injectors , still the difference was massive. So you will be grinning from ear to ear coming from 225 with anything remotely close to 300. Proportionately its more for you because the transmission loss is almost the same.

On the twisty stuff Id advise a 30mm spring drop , shocks can do with a bit of a helping hand too.

Otherwise even though you have done the brakes. you will still find yourself running out of road. It felt on every bend like you were tottering on the edge of a cliff with your just your finger tips.

My advice to anyone would be do the brakes tyres and suspension first.
Pirreli have a good slogan on that . Sure you will remember it.

 

This is interesting , but what about the torque curve.

I went to a large TMIC from CX racing USA , mine has cost me some spool up response as greater internal volume still has to be filled.

You might find on the TD04 which spools nice on the STD but if you go for a larger TMIC that some of that response is lost , but the Volume of the Sti version that Matt suggests is not a huge differnence , might be ok.

Changing one at the time of Mapping is a 10 minute Job , so you might want to try a Sti IC and see what can be done at the RR. The problem about using the small WRX one is you may still get 2-3 runs in before the temperature overwhelms it . So in relality the Sti one will give you performance for longer and more reliably for hotter days.

Cooling them down with water is a good idea. As is heat wrapping / shielding the exhaust from the IC .

 

Like they say STI TMIC/Undertray/scoop isn't essential but it's a reasonably cheap mod, adds a bit of power and more importantly helps keep inlet temps down which adds a bit of reliability and better MPG.

Like I say though only get it if you fancy having a crack at 290-300!

 

No brainer really, reasonably cheap future proofing mod that can be done by your wife and does give other benefits over just BHP.

I think I lost a tiny bit of spool but it'll help top end where the TD04 becomes inefficient.

TBH funds allowing do as many mods as you can before a map as they all add up.

Even STI Pinks and a Walbro are advisable in my opinion when exceeding 280bhp, all help if you get a boost spike from a split vac pipe on an icy day...

 

+1

 

I've now had 7 maps, and each time I've been nervous, in case something goes wrong and some expensive damage is done!

Its strange, I've had maps from mainly Duncan and Simon, and not a single one took more than an hour!

Although, they were all stage 1 and 2 maps.

 

I'm learning some good stuff here guys, keep it coming! Much appreciated!

 

Just 1 thing matey....................you can never have enough power, i went from 270 to 354 to 436 and i still want more

A turbocharged car will ruin a bank Balance quickly

 

I Second that.

Windmill

Mine are the WRX 06 Dk blues flow that same cc , I got mine on here for 100 , they take 2-3 hours to fit , depending if the wife has smaller fingers. The pump is a 20 minute change (do re-use original mesh filter), expect to pay 80 up for that. If you don't there you will end up maxed out on the injector duty cycles at close to 300bhp , and as Matt says that can be a risky low fuel/air ratio that's a . so don't ask the tuner to try push it otherwise.

Like to see a post the HP / torque curves on the TD04 when its done
it reminds me of what I miss.

If you can't afford the injectors/pump then try tapping in the case of the FPR with a hammer. Its a lazy way of upping the static fuel pressure a bit , but have a STD 43 psi spare available as its easy to overdo it and you can't take a dent out that's too deep. The STI & JDM's make around 50-55 psi you won't get as much pressure at your new higher boost without a uprated / sti fuel pump but it will give you a little more safety margin.

 

Hahaha Never a truer word said!

 

When I had mine 2 stage maps done we spent 2-3 hours doing it , but he did say he had to work hard on mine due to character of low end , it turned out that my after market WG was opening very early. Later checked 0.25bar and I was losing ramp to max boost due to that. However If the car has a std turbo and maybe just had a 255 FP and 550 Injectors JGM would have had a passable data set to hand, which just needed minor tweaks. The second stage was really the same as the first but called for 0.2 bar less. Its a shame all that knowledge has been lost to the UK community. We will miss him.

 

Matt said "Injectors and Walbro are advisable in my opinion when exceeding 280bhp, all help if you get a boost spike from a split vac pipe on an icy day..."

IMHO even a 1/4 tank of 95 Oct. The ECU will had nothing left to compensate the AFR. IF you see that your Injector duty cycles at 90-95% , and they likely will be for a 440 cc light blue on decat pipes + TD04 getting close to 300 bhp , then its worth paying some attention to Matt.

Windmill , Ask your tuner tell you what duty cycle he ends up with.

As a guide here most start to think about the next size Injector at 85% and certainly do change for more flow if you plan any other mods.

 

Its strange, I've had maps from mainly Duncan and Simon, and not a single one took more than an hour!

+1 mine less than 1hr too with JGM 👍

Time taken depends on the state of the car.

In my case Simon took a previous map with a car that had TD05 16g and Walbro255 /550cc's the first down loads and road test were done in 30 mins , however although I was grinning already he was not full satisfied.

The extra time taken depends on the way the car responds , mine stutered briefly at low speed on a sudden full throttle application , took ages to iron it out. Then would still only reach 1.0 bar till we found out that the Aftermarket WG was opening prematurely, we adjusted pre-tension to 3mm.

All that pfaffing around takes time.

 

I still don't know if the 2001-2005 WRX comes with 380cc, 420cc or 440cc injectors.

AF website states the former but most on here claim the latter or middle!

One thing for sure the STI at just 265bhp has an uprated Fuel pump, injectors and TMIC. And Subaru know best!

 

wrong as usual the standard sti doesn't have an uprated fuel pump,the uprated pump (walbro) is only fitted to the 300 bhp PPP version.
I have the paperwork from new on my ppp sti and the pump is part of the pack.

 

So the STI and WRX have the same size pump? I thought the 01-05 was 130lh WRX 145lh STI.

 

no idea but the standard sti doesn't have the same pump as the 300 bhp PPP version.
I removed mine an replaced a while back and it was a walbro 255.

 

My point was uprated over the 225bhp components of the WRX.

I think the STI is uprated but I can't find info for the 01-03 STI pump.

 

Your correct that they are different , ( they have different Pns ). Would not like to say if the lh is exact as quote though thru the MY's.

Taken from NASIOC

2002-2005 WRX fuel pump 130 lph
2006-2007 WRX fuel pump 145 lph
2008-2009 WRX fuel pump 155 lph
2004-2007 STI fuel pump 145 lph
2008-2009 STI fuel pump 175 lph

 

Also correct

According to SAC2564 (original Sub # WRX sti performance package)
305PS at 6k previously 265PS on std Sti engine on 97RON

Extra Key features : "High capacity fuel pump" , Recal ECU / High flow Cat / SST Exhaust

My car is a PPP SAC2565 ( original WRX # WRX Performance Package )

Key features do not include uprated pump , So I had to get the 255

 

I believe therefore an uprated Sti pump (performance package) will be 175lh

Perhaps someone at Subaru can check this via the VIN# although in my experience that does not always help much as the Prodrive items were added in the UK just before final delivery , even after 25 years here I can even speak dialect but still nobody has a clue what I am on about.

 

So Ralph, wenn Sie vorbeikommen, um Blighty so Billy kann deinen Arsch zu vergewaltigen.

 

Hi Matt , dein Deutsch ist noch schlechter als meins. LOL

Leider habe ich meine Ehe Scheidung zur erst
und dann sehen wir ob Geld noch da ist.

 

Good stuff Kumpel, wir werden dann zum Tweaks und unsere Autos zu testen gegen brina drei. Oder wir können für Yorker Raceway warten.

 

Unfortunately I can't afford new injectors and STi TMIC as well as everything else at the moment They will be next on my list along with a bigger turbo perhaps.... but that won't be for a while yet!

Ahh the name Duncan rings a bell, I think that is who is doing mine on Friday (fingers crossed) does he have a good reputation? I will ring TFS today just to clarify what I would like doing and I'll find out who is mapping my car and try to speak to them as well.

Thanks again everyone for all your help and advise, it makes for some interesting reading!

Rob.

 

I just clarified with TFS who is mapping my car and it is Duncan at Race Dynamics. Anyone had any dealings with him/them?
