Just wondering where these numbers came from?. was it a 90-94? i am just curious cuz i owned a couple awd talons and stock hp was 195 at 12.something psi. my last one before the sti dyno'd close to 270 at provenperformance at 16-17 psi. this is by far any astronomical feat since ive seen talons pushing 400 and change as daily drivers and 600 as race cars.fwd or awd they were all close in hp comparison.

was just wondering did you have a non - turbo and put a turbo kit on it or something?

Ummm yeah. TurboXS has tested every STI ever built. They can't be wrong, right? If you want to provide real technical evidence to back up your claim, I'd like to read it. Hint.

Az2004sti- I kknow you are back and forth with dan from godspeed re turbos and stuff, ask him his opinion on what I stated, he can explain it way better then I could.

Hatchy and Hummer- I offered my help on something that has been proven over and over, if all the top tuners are saying the car has a detonation problem AND subaru issued a fix by sending out a reflash, doesnt that tell you something? Theres detonation problem, I think it needs to be fixed on a bone stock car nevermind when you start modding and so do a lot of the tuners that post on here. I could care less if you correst the problem I was just trying to help. Talk to shiv or dan or someone at tubo xs and ask.

I didn't ask for your help, merely responding to your "guarantee" that all STIs ping on 93 octane at 18psi. Until you udnerstand why the STI pings, please don't offer guarantees.

Go f uck yourself. Is that a good enough guarantee?

I hope you blow your motor you moron.

I think I know enough about turbo cars, I know enough about my car too it;s you that needs to do a little research

Oh wait I almost forgot.... you have the only STI in the US that doesn't detonate!! My bad.

You bought it from the dealer that sold Jack his beanstalk beans right. Get a clue idiot, your car pings like everyone elses does unless you have a 100 octane pump at your house.

I wish you lived on the east coast so I could bet you money and use my friends dyno to prove this and teach you a lesson.

Take the Ridlin and settle down. Cursing at other members only makes you look foolish.

1. ALL STis do not detonate. Whoever told you this needs a serious clue.
2. There are variables that make the STi detonate. Some of these variables are ECU code, fuel octane, and temperature.

Relax and enjoy your car.

Any idea how much a port and polish of the turbo would cost? Would doing this be detectable by the dealership in any case?

No kidding I'm not the first person to port a wastegate, or any other car part for that matter.

I didn't even know if it would work, but it did. I researched it it on the net to get tips, so of course it's not an original concept. But I take credit for bring the concept to NASIOC and the US subaru community. Austin also deserves alot of credit, I bounced the concept off him, then he did it after me and made a nice writeup.

(I won't even go into how I did it outdoors on one of the coldest weekends of the year, at a "garage day"....that's a little NESIC legend).

You two can bite me.

Sure - that has NEVER been proven. The only data that I saw would actually show the contrary. Vishnu dynoed a car before and a different car after the reflash and the reflashed car had higher peak numbers. The post is somewhere, but I don't think a dyno, a/f, or anything else was posted. This was also different days, different cars, and different conditions, so it is hardly a valid test.

Someone needs to do a proper test.

Hey, I was one of the first if not the first to bring the wastegate port solution to the forum. I deserve some credit as well. Most of those internet links posted in the beginning were first posted by yours truly. I just never got around to porting my wastegate yet. It has been delayed because I was on vacation for 2 weeks.

Damn Kevin. I wouldn't have the cojones to do it outdoors. I'm going over to my buddies heated garage to attempt that later today. I'm a tropical person by birth. I was on vacation in the tropics to escape the cold weather.

wgknestrick- nice post,
Here's another site to add:
http://www.gnttype.org/techarea/turbo/turboport.html

GSXR and Carguy19. The problem with boost creep does not relate to damaging the engine, but to overspinning the turbo to pieces. The vf39 is close to it's max performance in stock form. Anything over 17psi is overspinning the turbo, I believe. I've hit ~19psi and rising on a boost spike. I've also read a thread on here somewhere of a guy who has already blown his stock turbo with a boost controller setting it at higher boost.

I'll take some pics to add some info to all the nice writeups by others on here when I port mine later tonight.

Guys, wastegate porting has been around forever, its nothing new!! I donít see how anyone can lay claim to introducing wastegate porting. In the DSM world, wastegate has been proven way back in the 90ís to fix the same problem.

If you dig back in the archives, you will see that a few members ported the VF39 wastegate way back in May to combat boost creep with a TBE.

I just wanted to post on here in efforts to say that there are plenty of STi's without ping problems. We have a group of 5 of us in our town and 3 had ping problems, 2 of us didn't. We stood outside the car (carguy) and still didn't hear it. Was in the 3 other cars, so we knew what it sounded like when we were in the car, still didn't hear it.

I don't know what to tell you. Some people have it, some don't. I'm fairly sure no one can say for sure why, but there's nothing like cold hard facts to punch holes in someone's argument.

As to what I think you're going to reply with that you are helping people, and I completely agree with you. There are some people who replied with lame ass flames toward someone who was trying to help them and warn them of problems. But to come back and flame again is just stupid. Let the bigger man bow out. The intelligent people on this board can see who's a bigger man.

To those that have ported your own wastegate, what did you use? Where did you get it.

thanks....

Hah, I know. I just wanted to jump on the 'toot my own horn' bandwagon.



I ported out the wastegate tonight. Took me about an hour of actual porting and no more creep!!!!!!!!!!!

Sorry people but I forgot the digital pictures. It's really very straight forward, though. I had my STi mechanic friend help me in taking the turbo out and in the porting since he has a garage and lift.

We just used a carbide grinder and then a drum sander. It was pretty quick work. We ground out the wastegate hole at an angle, making it wider at towards the bottom. Probably took out 75% of the lip all around. Most of the metal was shaved below the lip to make a funnel-like shape. We smoothed out the edges a bit and presto. Did numerous runs to 5th gear redline shifting to sixth for a short while. Boost was steady at .11mpa peak.

Trey - my friend had air tools but you can get a Dremel at any hardware store and get a grinder for it and a couple of drum sander bits.

Taking off the turbo is not as hard as putting it back on. those damn hoses.

to take off the turbo you must take off the downpipe, intercooler, and then the turbo.

However, I heard, not sure, that you can just take off the exhaust side of the turbo housing and leave both turbines in the car. That way you just need to take off the downpipe and unbolt the exhaust side turbo housing from the uppipe. Use WD-40 on the nuts and bolts, gets those subborn bolts off easier.

If you want to take the turbo off:

take downpipe off (5 bolts/nuts)

unclip the wastegate arm off, in the middle of the solenoid and the actual wastegate, there is a "C" clip that comes off, right where the arm does a 90 degree turn downwards towards the wastegate.

take off the intercooler by unscrewing the 2 bolts that holds the intercooler down. Then take off all the hoses that attaches to the intercooler.

unscrew the turbo from the up pipe (3 bolts)- the bolts are positioned in a triangular shape. Make sure the gasket is labeled and put back the same side up. This is the same with the dp or you will get leaks. Or maybe it only can fit one way

?

The drain the coolant from your radiator, and drain your oil. Maybe no need change drain the oil, but I did anyway. But you must drain coolant unless you don't mind it spewing everywhere.

Take off all hoses from turbo. There are 2 water coolant hoses (in and out) sounds like a sex movie . and 2 oil hoses (in and out again) heeheehee he said In and out. However, the oil in is actually a metal hose which needs to be unscrewed, looks like brass color right on top of turbo. There is also that hose that is right below the turbo and it runs stright down, that is a bitch to get to. The trick to putting it back is to take the hose off and put it on the turbo and install it that way, because the bottom place where you attach it is actually more accesible to reach, than pluggin it to the turbo itself.

take off wastegate solenoid mounting, so you can make room to remove turbo.

Take turbo out and throw it on the ground, no more boost creep.... just kidding.

since you are going to grind the wastegate, there is going to be a lot of metal dust flying around. So it is best to cover the turbines and plug up all the holes, except the wastegate hole. .

get spray paint and spray the wastegate area when the waste gate is closed. Then you know where the wastegate sits around the hole.

Then grind the heck out of the inner part of the spray painted circle.

Then put the turbo back on. It's kind of har to line up the hoses, but you need to be patient and use your jig saw puzzle brain.

As for the intercooler, I took off the driver side, intercooler bracket to make more room.

You may need to take off some additional stuff just to make room to get the pieces back on.

when you do the install, do everything in reverse from how you took things off. Such as: put turbo on before you put the intercooler on. etc...
