[Turbo smart dual port BOV (loosing power?)]

Shot guys! I think I sorted it  drives like a dream now 

[Turbo smart dual port BOV (loosing power?)]

Hey bro! Yeah I did. I made sure it was closed upon idle, I adjusted it up from soft but just not sure how hard or soft I should go 😀

[Turbo smart dual port BOV (loosing power?)]

Hey guys I have a stock 2005 V9 WRX STi

i just installed a turbo smart dual port BOV, i adjusted the BOV to soft and took it for a few runs on boost to sort it out and to make sure it releases properly under boost. However it kinda feels a lot slower? As in the revs feel like they drop more in higher gears than they used to? Not sure where to go, do I need a tune? Just rather ask on here before someone makes me spend extra money for a tune if it’s just a simple fix. Cheers :)

Hey man! Sorry for late response been mad busy with life in general. Got the dyno check at torque performance for $200. Cars pushing 210kw ATW in 4th, 6000RPM on 19.3 PSI. Fuel to air ratio and everything is sweet. Dude said as long as I run 98 she’ll last forever. Only thing is halfway between peak it dips for a second before full boost again. Not sure if it’s anything urgent or not though, I can send you a pic of dyno sheet if you have Facebook, or insta? Cheers bro means heaps

hey man, 19psi is ok for a tuned v9 to hold 

usually drops in the higher revs ..

with catless exhauts, they do spike a bit and normally its the spike that could be the issue ..

either way, with a good tune, they get safer and can run that boost well..

 

will pm u..

 

is your one a black v9sti?

surprisingly, we just tuned 2 black V9's in the last few weeks with similar setups...

 

Hey man! Sorry for late response. Nah mines silver, I’m gettint a fam friend to do a dyno check on it to see if it’s running mint. Then I can see where to go from there

[05 V9 WRX STi peaking 22PSI]

Cheers man, that’s so much! I’ll def look into the tune. The cars fully stock and only has 50,000k’s on the clock. I just put the second Set of tyres from the factory that’s how untouched it is 😂 I really want to make it quicker but at the same time I want to keep it fully stock because it’s such a good exemplar of s sti

As long as you're running it on 98 it's not going to do anything bad.

 

I have a V7 STI which only has arguably marginally stronger internals and I've run something like 26psi from a WAY bigger turbo through it and it didn't die.

 

I ran it (untuned) for like 2 years with a downpipe and exhaust and it was hitting something around 21-22psi all the time and it didn't give a damn. Just run good fuel, don't thrash it when it's cold, and factor in getting a tune somewhere down the track - budget $1500 and get a high-flow panel filter, a 3-port boost solenoid and an aftermarket fuel pump just for good luck, car will probably make a safe-as-houses 215wkw and drive bloody nicely too.

 

Ight cheers man, yeah I always run it on 98 and I only go above 3k rpm when it’s at normal operating temp. I play it really safe all the time

If you are wanting to play it extra safe (which is what I'd be doing) then go and speak to the tuner and see if they will book a dyno slot for you, but if the initial baseline test looks good and you are happy with it, agree beforehand that you have the option to stop there and only pay $x i.e 2-3-400. 

A decent chunk of the work of getting it tuned is setting it up on the dyno, checking everything is working fine etc.

 

PBMS are a good bet I should think, personally I used E&H motors to tune my standalone ECU and I'm very happy with the results. Karl Ruiterman has a lot of experience with subarus and used to be the only option in Pukekohe until PBMS got back into tuning.

Alright thanks heaps bro! I’ll def look into a tune. Just want my car to be running as healthy as she can hahaha. Cheers again dude 

[05 V9 WRX STi peaking 22PSI]

Hey man, yeah It holds at 19 however when I hold the peak warning it flashes at 22 psi and when I first got the boost gauge the peak warning was 19 so sometime it must’ve gone to 22? I have no idea how. I spoke to last owner and he didn’t get a tune done with the new exhaust  so a bit lost now!

Most places will do a o2 monitored dyno run for less than $200. It obviously doesn't lessen the cost of a tune if you do need one but it'll let you know straight away how the current tune is and whether it needs a re-tune or not.

Hey man. Spoke to the last owner he told me he didn’t get a tune done but the catless downpipes look to be professionally done. A bit lost now as I will probably have to get it tuned to support the high psi? Which = more damage on internals because of higher PSI? Or I’ll have to lower the power and get the exhaust re done to lower the PSI? Either way I think I’ll need a tune.

Get it on a dyno with a wide band o2 hooked up and see what the tune is really like. 

 

Then make a plan when you know what’s happening. 

Could have been tuned when the exhaust was done. 

Hey man. Yeah will do, dude at Subaru said most likely there is a tune done however I have no way of finding out who did it and when. Possum Bourne quoted $1200 for tune and dyno  

[05 V9 WRX STi peaking 22PSI]

Hey guys! I’m the second owner of an immaculate  Japa Import 05 wrx sti. I bought the car a year ago with 39,000 original K’s on the clock hence why I’m always worrying about it😂. Long story short, I bought this car off of a 75 year old in CHCH he had put a “RAGE” exhaust on the car. Took her to the local Subaru dealership today for a service and the head mechanic told me that I’ve got an aftermarket cattless downpipe hence why my heatshield for my turbo is gone and this is probably the cause for the 22psi peak However in third gear if I WOT between 3.5-4k rpm it shoots upto 19PSI and holds there as if my car is really pushing 19 PSI. The car is now on 55,000k’s I get it serviced every 5,000k’s, check oil and coolant every Friday. And I can literally count the amount of times I’ve boosted first gear, she’s never been launched and I always wait till she’s warm before going over 3k rpm. Is this high boost level anything to worry about? Or should I get it tuned either to support the 19PSI or to lower the PSI to make sure she’s running safe. Just want what’s best for my subie 😊 TIA

[05 WRX STI Foglight decals]

Hey Guys!

 

im getting my front bumper re-done as the previous owner lived on a gravel road and the bumper is covered in pimple like rock chips all around the front of the car. I have the original/stock sti foglight covers with the original “STi” stickers on top of the foglight covers. As the condition of the bumper is pretty bad I’m 99% sure that the body worker will have to remove the stickers to repaint it. Does anyone know where I can get genuine or good quality stickers as I know it’s just a sticker but this car is an amazing example of a stock sti with only 2 owners and extremely low k’s. 😀😀

nothing behind the glove box that turns up the boost - unless its a hidden boost controller setup there

from factory there is no wiring there to do any boost changes.

 

the pump change is just a safety measure and also means after a tune you will not be potentially running out of fuel pressure etc..

 

check the boost solenoid and see if its still stock and maybe peek behind the glove box in case it does have a hidden unit

 

for the sound - ur stuck with the twin scroll sound but with the right muffler it does sound pretty nice (i somewhat prefer it over the traditional one actually - the x-force mufflers seem pretty good but im sure there are others)

 

what was the result of the compression test?

 

Hey man ill have a little look but I might just go straight to either torque performance or the tuner you recommended. I got the muffler put back on as I failed my wof and it sounds really good for a equal header so luckily that’s one problem Gone. The compression tests cane back really good (as in even) I’m just at work at the moment but when I get home I’ll try post a pic of them.

hey man,

strictly speaking - the cat delete does NOT need a tune in this model ecu

But the higher flow it allows will be best to get a tune so you dont run into fueling issues etc

 

the boost may be raised due to the higher flow and thats where the issue is: it may not be fueling right for that flow since 22psi was never a stock option on that model.

Also, how did he turn the boost up? is there a boost controller in the car? maybe turn is down for now?

 

Confirm as per above :

no vac lines are leaking

what fuel pump you running

 

if you are ok to make a trip to South Auckland, then i would recommend @Subirex Automotive for any maintenance that needs to be done.

diagnostics can be done there and also tuned for the ball of mods you have

 

Hey man! He said you can turn the boost up from behind the glove box? Or something like that. As far as I’m concerned the fuel pump is still OEM but when I did the full service aka compression test, exhaust leak check rady ra they said I’d need to get a new fuel pump eventually however atm it’s still fine. (Bit of a dummy) ahaha

Just get it running right and stop worrying about the sound.

Yeah I’m still going to get a diagnostics on it but as the cars on 43,000 original k’s the  previous owner took the cats off after 700 k’s so the cars been running like that since. I’ll still get a diagnostics done tho!! 

[05 WRX STI STRAIGHT PIPE Questions]

Before I make any decisions are there any exhausts out there that you guys reckon sound good for a EQUAL HEADER STi? seen the Tomei exhausts but not really sure

[05 WRX STI STRAIGHT PIPE Questions]

yeah thanks guys! Yeah I’ll probs revert to a resonator and muffler just because I’d rather it sound all right then wanna be in equal headers 😂. Once that’s done Ill look into tuners. Are tourque performace out west any good? They would be my local tuners

[05 WRX STI STRAIGHT PIPE Questions]

Ffs I’m an idiot I’ve got so much work to do. 😡 Im used to subies having unequal headers so idk how it slipped out of my mind (rough couple months blah blah) Got a resonator delete today and the previous owner has removed the cat which I didn’t realise until the resonator was gone so now I have a bloody 3 inch straight pipe which just rapes people’s ears. Sounds like a bloody loud honda now! been told if I remove cats I need to get a tune for the secondary 02 sensor however I’m the second owner of this Subaru and there’s no warning lights etc but he’s certain he DIDNT get a tune after removing cats. He also mentioned he turned up the boost to 20-22 psi and when I’m on the motorway in 5th at about 4k rpm and I ease my foot I can feel the boost cutting in and out so would this back up his point of “20-22psi” don’t know where to go from here I’m fully lost with what’s true and what’s not .just want my car to be a reliable and fun car to drive!! What do I do!?!???

[05 WRX STI STRAIGHT PIPE Questions]

Hey all! 

 

Thanks tons for the info! Im probably just going to go with a resonator delete as this car is fully stock and I still want to keep the reliability and "stockness" of the car as I still even have the full factory exhaust in my garage  I just want to have the iconic subie rumble which HOPEFULLY I can achieve w/out  getting tunes done etc. (however ill be making sure whatever I do wont damage the car etc) Awesome feed back from all of you guys im extremely impressed with all the honesty from your comments. So thanks tons! 

[05 WRX STI STRAIGHT PIPE Questions]

Hey guys!

(new to the forum so sorry if anything is misleading)

 

I currently have a stock 05 WRX STi apart from a Muffler delete. Looking at getting a straight pipe on my STi. Talked to my local Pitstop who told me he is unsure about how the "secondary 02 sensors will cope and that due to this I cannot get my cat removed". Looked online and apparently after a straight pipe you need to get an ECU tune done so that the 02 sensors dont freak out. Can anyone shed some light on what I should do in a step by step for a straight pipe so I dont mess anything up as this car is my pride and joy. Also does anyone know any good ECU tuner's in AUCKLAND as thats where im based! cheers guys and gals!!
