Porting the WG isn't easy, its a few hours in labor. Theres a member that sells restrictor plates, somewhat pricey but it beats making them yourself. GL.

catch22, leave the high flow cat on. A midpipe with stock w/g will most likely pop your motor, which is around a $5,000 fix.

I don't think thats entirely true if you don't know his full mod list. If you have an upgraded fuel system(pump, inj, and ecu) with a good tune do you still have to port the W/G?

. I dont need to know his mod list, because it isn't relevant. None of the parts you listed will mitigate boost creep. All that matters is the stock internal w/g and lack of exhaust backpressure. Some FDs will creep to 20 psi and beyond with an open exhaust. If you don't get creep to at least 15 psi, then you have weak turbos. The boost creep will be much more pronounced in colder weather.

i been cat-less for 3-4yrs now. going mp was the best mod i ever did. I dont get boost creep either and i have used two different exhaust systems...the n1 dual and the rb dual as well as resonated and "un"-resonated mp's. I am sure my turboes arent tired either for 2 reasons 1) my car had 19k miles on it when i first took the cat out and 2) the car builds boost instanley and holds it till redline not to mention the car makes awesome power for its mods.

My best advice would be to DEFINATELY get a mp. if u have issues sell it.

You are using only one data point out of about 10,000 FDs here in the U.S Matty. I've been around over 500 FDs over the years, to include working on and building them, and yours is the first instance I have heard with no boost creep. You're telling me that with your boost controller off, you see 7 psi to redline
Regardless, odds are he'll have uncontrollable boost with an open exhaust and stock w/g. You can always watch your boost gauge like a hawk when you are WOT those first few times. Hey, they're not my apex seals, do with them what you will

Are we having some sort of miscommunication? dont make me start a thread...lol. i am talkign about having all the supporting mods, power fc, more fuel etc. by the way the power fc controls my boost perfectly...no need for a boost controller.
Rich i wasnt saying u are providing misinformation, i was saying there is misinformation "outthere" sorry if that wasnt clear. The fact remains however that some people dont get creep , how can u turn soemone away from posible 40 rwhp for $150? let them test it out and see if they are one fo the lucky ones like me.

i love this topic b.c its so controversial...it seems those that get creep get so adamant about boost creep and always warn against going mp....then in the thread there are guys like me that chime in and claim no creep. listen i have used a few different exhaust set ups and run the **** out of my car in hot or cold weather and can control my boost to whatever psi i set my power fc at.
With so many people not gettign creep it is poor advice to say dotn get a midpipe. the proper advice is what i am saying in this thread and which is mimic'ed below
here ya go rich...i always thoguht this was the general logic:

The main thing is if you increase your boost, you need to increase your fuel. So if you plan on running higher boost levels with your setup, you need to look into an ECU upgrade.
As far as boost control, it would be a good idea. If you aren't going to upgrade your ECU then you'll definitely need something to keep your boost down around stock levels.
Whether or not you need to port the wastegate or add some restriction to the exhaust (restrictor plates) with the midpipe will have to be a "trial and error" process. Just be careful when testing.

I *am* arguing with this logic: "My car was fine, so all the others will be fine too. Slap the midpipe in there and away you go"
Boost creep can blow an engine in a heartbeat. Having 'enough fuel' doesnt do **** if you aren't tuned for it, and if you just installed the midpipe, you arent tuned for it. What happens if you go WOT and don't back out quickly enough? Exactly

.Alright I see where you're coming from, but my post earlier specifically said having a good tune, which would imply being tuned for it.
I just showed concern because i am putting my MP on(and plan on getting it tuned asap).

i thought u were advising against mp b.c it almost always causes creep, i guess when u said out of the 500 cars that u have seen mine was only one without creep led me to beleive this.

Creep occurs because your car gets to 10psi, or w/e you have your boost set at and then the wastegate opens so that the turbos don't keep spooling and go past 10psi. If you have a midpipe is makes it easier for the turbos to spool so they get to 10psi, then 11, then 12.
I suspect you do most of your driving on the street which means under WOT, or for that matter most of the time you drive, your looking at the road and not your gauges. You wouldn't probably know you had boost creep until it was too late. The people on this forum don't type the same things over and over for the hell of it. They know their stuff.

your joking right? did u read my previous post that says i been around here for a long long time? i know what creep is. if you read this thread u would have seen that my arguement is that not all rx7s creep when a mp is installed. It is best to go aheead and install one to see if u have creep or not. it costs 150 for a mp that could yield up to 40rwhp at your peak. dont u think its worth a ashot?
dont preach to me. what i have posted in this thread is 100% accurate. if u chose not to follow my advice then poor u.
also what the hell does street driving have to do with anything....i guess when your going 120mph on a road track thru twisties it easier to monitor your gauges....wtf?

If your going to get a midpipe, port your wastegate, period, end of story.
If you take the turbos off your self and take them to a machine shop to be ported it costs about $40, I just had mine done. That is a hell of a lot cheaper than upgrading the fuel system and getting a tune, it is also a hell of a lot cheaper than blowing a motor.
I don't understand why this is such a big debate.

u are gonna opreach your **** w/o having read the thread...good work. whjy would i waste my time talkign to you? let me give u alittle advice...lsiten more talk less!
upgrading the fuel system and getting a tune is the only u are gonna make power with or wiothout a mp. a good tune is the best money u will spend on your fd.
my wastegate is not ported i control boost perfectly fine for 5 yrs. tks. the same goes for a ton of people here. u came posted comments w.o reading the thread. thats a big no no. noone is recommending that u dont monitor your boost when u first install a mp. whats being said is very simple...not all midpip;ed rx7s have boost creep. its something that u need to test out for yourself.
