hi everyone, just purchased my first subaru , must be 1 ov the last ones its a 2.5 hawkeye 2009 on a 58 plate only 14k , i love it ,its pristine & pulls well, ok so that out the way it has a ninja tailpipe but thats it , i want to get it up to the 350 370bhp mark what mods will work best & will a £1500 budget manage my goals ? like i said first subaru so all feedback will be app will post some pics soon

 

I believe remap will bring you close to desiered number (if you have 2,5 STI that is)

 

Hi,

Do you Have a warranty with the car? If so then it will be void if you remap? Only thing that will keep warranty is if it's the ppp package!

Also is it sti or wrx?

Doug

 

STi or Wrx? STi mean easy Wrx means hardwork and things might start breaking apart at that power!!!

 

yes sorry , its sti have full waranty but as long as its proven tuning mods i use i see no probs , yes remap , is ecutec recommended ? scooby world said just now they would remap panel filter upp fuel pump & cat back for £1k said around the 320-330bhp ? so if i go ahead how do i get my other 40bhp , shud i go with the panel filter guys or are stand alone much better on this engine?

 

Na.. go with full 3"decat turbo back, walbro pump, good panel filter maybe a 3 port solenoid and a remap you will be laughing bye-bye to 330bhp..

 

wont pass mot with turbo back ? am i right ,,

 

Yes you wont.

Try panel filter,3 port selenoid and walbro....cheapest tuning stage.

 

Sports cat it and you should be fine, look at Cobra Exhausts there good quailty and well priced. 3 port, decent panel filter K&N, 255 fuel pump then remap.

Only my opinion though.

Rich

 

thanks wil def do the solenoid pump filter & ecutek map ,was thinking nur spec r or milltek for exhaust also should i change the spark plugs or are the stock items fine also wich is the best oil for the sti , price dosent matter i just want the best liquid in her

 

The second you remap/exhaust etc you will lose your warranty, simple as unfortunately, there is only one tried and tested modifications pack that does not invalidate your warranty and that is the ppp.

Tony

 

yea thanks tony just phoned my local dealer & he Q me £1900 for the 330 upgrade ? im also confused , i forgot 2 say earlier it has a forge dump valve on ,, he just said to me take it straight off or subaru will void my warranty ,, it breaks engines ? wtf is this true

 

As above comment, Check with dealer how much they`d charge if your bothered about the warranty which I imagine you are. Good luck with your project.

 

just spoke to revolution they say never heard of a forge breaking an engine ??

 

The original re circ valve is best for the car anyway! Ppp is your only option to keep your warranty but don't think it will make anywhere near 350bhp but could be wrong!

Doug

 

You wana keep the warranty then you can forget modding anything to it, almost any engine power upgrade would invalidate your warranty. Your other option is go for a prodrive pack upgrade, for around 2 grand for an exhaust filter and fuel pump with crappy map too!!!

 

2 be honest im none 2 bothered about the warranty , sure it helps but the car needsmore grunt so ,, just looking scoobyworld have a special offer on a stage 1 tune for £899 for 330bhp guess thats the starting place for me if i junk the ninja tailpipe & go for a nur spec or miltek cat back i may get a little more will book it in nxt cpl weeks & see from there what my options are ? thanks to all for the replys

wow thanks daijones

 

thats just great ,im from newcastle so andy forrest is 2hrs up the road just had quick look at his site & emailed him / yep def goin with him now ,, thanks so much guys

 

If it's the 3 year manufacturer warranty then it is worth something. If it is just the main dealer 12 month warranty because you bought it from a main dealer then it's not worth much and hardly covers anything. I was reading the small print and it says it doesn't cover cracks in the cylinder heads or block as well as other bumph (basically meaning it doesn't cover any engine failures what so ever (modded or not!).. and also cheekily says it does not cover known manufacturer faults and recall items.. WTF (I think I would fight that one in court)?? It really is a useless warranty. My old Nissan warranty was far better. Subaru should take note. So if I were you mod ahead I have the PPP (prodrive performance pack) and the map is pretty bad.. very lumpy in low gears.. making it very hard to drive, not smooth at all, but does give a nice shove of power but tails off. The PPP only gives 310-316bhp though. Far better off getting a custom remap. 350bhp and 380 lbs.ft is normally the tops with a stock (standard) engine. After that you need to look at rebuild to make it more reliable, allowing you to take it to 370+. Im sure Andy forrest will point you in the right direction. He's one of the best tuners. Or a company called Race Dynamix, again very highly recommended, do custom remaps but at a lot lower cost as there is no license. Duncan at Race Dynamix tuned my car and it is now very smooth and producing healthy reliable power. He also travels to your doorstep and goes all round the country. You need to show us some pics of your new motor! Hayward and Scott do one of the best custom exhausts for the impreza. BMW M cars have a lot of custom exhausts done by them, but they're very reasonable prices too.

 

thanks matth 76 / yea sure how do i attatch a pic on here anybody? it says on bottom of page posting rules i may (not post attachments ) wtf? any ideas - & il send some pics straight to this thread

 

ok guys figured out the pic upload in options DOH!!!! ha ha , yea so 2 picks ov my pride for you.s 2 browse ,, she.s a 2009 on a 58 plate

 

What is the std turbo on a 58 plate STi?

 

std? its an sti

 

Standard - OE - Factory Fit - take your pick

 

sry m8 , yea if you read the thread its got a ninja tailpipe on & a forge dv , but not for long he he

 

I'm thinking you are missing my question. What turbo does Subaru fit to a 2008 STi in the factory?

 

I think it is a vf43 or possibly vf48, unsure when the 48 was introduced! Both good turbos with a proper remap.

Doug

 

VF 48

Great turbo
