Hi Guys,

Just after some advise on what i could expect if i was to get my Standard MY05 STi remapped by perhaps Powerstation or someone similar.

Would i be able to see the other side of 300BHP and a decent torque figure?

Having had my car on the rollers, i know that in a 30 degree (which seems fairly hot) ambient temperature it produces 254BHP, and the rolling road detailed that when my car reaches 4k+ RPM it gets extremely rich with its factory map.

Thanks in advance for any help.

Your probably looking towards 340-350bhp and 330lbs of torque with an exhaust and remap (decat or 2nd hand sports cat).

Im kinda looking at keeping the standard setup if possible though at the moment (im not overly into loud exhausts if they arent needed)

Im looking for perhaps 310BHP'ish and around 300lbs/ft, do i need to start playing with performance upgrades for the car to achieve this? or can i get there with just a remap?

BTW: Its a Type UK.

You could get 310/300 with the standard exhaust setup, but it is quite restrictive, just cat back will cost you say 3-400 quid, a second hand prodrive sports cat, 200? so not that bad cost wise, 1300 ish?

I just had my spec c type ra mapped at scooby clinic yesterday( top guys) my car hit 350bhp and 370ltb which are realistic figures and apparently the most they have had from a spec c.

At the risk of stating the obvious,whats wrong with the PPP?.You leave your warrenty intact,will give you the kind of power increase and noise levels that you're after....and will enhance the cars desirability when the time comes to sell it

You went to the wrong place then

Can you get ppp on an malta import?

TonyBurns

iTrader: (3)

Yes but it will invalidate the warranty.

Tnx for the feedback guys.

So, with the standard setup (exhaust, fuel pump and air filter) on a Type UK STi... a remap should see me be able to get around 310BHP and 300lbs/ft?

I dont want PPP, and i dont want any other mods if i can help it since all i want is the above power outputs... nothing more.

you should really get an upgraded fuel pump to keep things safe mate,but if you're dead set on keeping std this should be all you need

do wonder if you'll get those sort of figures though, the PPP changes quite a few of the exhaust parts to get their figures (obviously with the ecu change) just wonder if that much will be reachable with an obviously very restrictive exhaust?

good luck though and please post up any results as i'll be going down the remap route when my warrenty is up and it'd be nice to know if i actually do need to trawl ebay for prodrive exhaust parts

marmski

Ye, no worries. No garuntees im actually gonna do it yet... just viewing the options.
At the end of the day, i dont want anything more than 310BHP.. so i dont see the point for an exhaust that can cope upto 400BHP etc... if i dont need it, because i wont use it. If the standard set up can cope with 310/300 then thats what im gonna stick too.

Nice thought on the pump though, heard the WR1 had a changed pump from the STi to the uprated... so that will be a mod i will get to be safe.

sensible way to look at it mate, personally i couldn't stand the silence of the sti so fitted a Prodrive backbox (trying my best to keep it as much like subaru had intended) i would like it to be a little louder but if this is all that's needed to get 300/300 i'd be happy without the higher outlay.

yeah, deffo go for the fuel pump. the std one can't supply enough fuel when you up the boost levels. walbro one's are only about £90

What makes you say that?

TonyBurns

iTrader: (3)

Because most of the "tuned" new age JDM's are pushing 10bhp more than that, ive seen em with 400lbs of torque and 360+ bhp though not much more than 360.
I did mention that Richard Bulmer can get a fair bit out of these more than most people can

Tony

juggers

iTrader: (1)

I dont understand...............one person says the turbo is only good for 350bhp another says suttun else.Tony is yours 360+ and do you have more ltb if so would you like to meet up and see how they fair in a strait line?

dynamix

iTrader: (3)

you are only going to be looking at 285 ish without chaning any exhaust parts or air filter

decent backbox and green filter and you should be close to 310 - 320

TonyBurns

iTrader: (3)

Mine is standard (previous rr day was 318/356)
The turbo is good for about 360bhp, its a more tunable engine than a uk car, the equal length headers mean better torque, though you can have a word with Spec C 57 who's car has over 360bhp and I think powerstation did the map for that, but they put out more power than what you have, i think I did mention where to take the car for a remap but if you didnt listen

I second this mate

Nowhere near 300 with the stock setup. You cant run much boost on the stock setup due to heat and the restriction of the stock cat.

Does anyone have a 360bhp powerstation tuned spec c?do you want a race.

TonyBurns

iTrader: (3)

Just speak with webby

Tony

i think i mite go for the hybrid turbo that should see me to 37/380 bhp?
400ltb?

juggers

Mapped by powersation

hoskib

only a small thread hijack juggers and tony

the standard cat is the problem with getting 300+ bhp then frayz? i assume this is downpipe cat?

dynamix

iTrader: (3)

two cats, restrictive centre resonator, restrictive back box and restrictive air filter

apart from that all would be great

with a deresonated centre section, decent (can still be quiet ish) back box and air filter will make the most of a remap - withouut it I would say you were wasting your money.

hoskib

iTrader: (1)

agree, but if the resonator is restrictive why is it the only part of the PPP exhaust to be left std?

dynamix

iTrader: (3)

got me on that one

spend £300 on new cat back exhaust and an air filter and then remap will be a better starting point IMO


btw uprated fuel pump is not needed at low level of tune.

I was there. It was bloody mint and sounded My 02 sti with full 3 inch decat hit a measly 334 but I was happy enough with that!

GazTheHat

Marmski, the above it correct. the others that have hijacked are not talking about your issue. And also, the pump will be fine with that setup. You'll probably as dynamix said, be around 285 with just a remap.

If you're after 300-310. You'll need a less restrictive exhaust and filter, plus the remap.

You will be able to keep the original bore size of 2.5" too, no need for 3" at that level.

New Parts:
Filter: £40
Full decat exhaust: £450
Remap: £650
*Walbro 255 pump £82 (*optional)

davedipster

That's cos it's not very restrictive. It's just very good at what it does-silencing.
That's why if you want the scooby burble on a 06, you need to change the center resonator. Not the back-box.
