Downpipe And Our Horrible Stock Turbo Seals

So I called up ********** to purchase my downpipe and the tech told me that installing the downpipe will blow the seals on my turbo. Rumor has it our stock turbo cannot withstand more than 300hp... reason being is that the downpipe will make the turbo over spool... SO WEAK.. Is there anything that can be done to prevent this such as COBB AP w. Custom tune?? I need some advice im sick of g37s and 2008 z's haha.
 
our stock turbos are fine. The leaking is because of the pcv system not bad seals. And any K04 should be good for at least 350 with some mild PnP and upgraded wheel.
 
With an Intake / Midpipe / MM & light weight 17's w / decent rubber I don't think g37's and 08 350z's would be an issue.

Should be good for Mid 13's 1/4 and from a roll you'll be like racing a low 13's car. I don't think a stock g37 or 08 350z would catch you if you're a decent driver.

Nevermind, I just read up on the g37 a little and those mods I mentioned would most likely just make it a race. Yeah you might need that DP lol!

here's an easy fix.get a regular mazda 3 and put a cold air intake,headders,exhaust.and a 40 hp dry shot,you'll be right next to a speed.and you have no turbo troubles to worry about
 
Can you elaborate(spelling)a little more on this,,i thought it was the seals that made the cars smoke when you got rid of the cats and such??

Just do some research. Many people have installed catch cans on the PCV system and completely cleared up their smoking issues. Adding a downpipe puts less pressure on the PCV system and crankcase and allows oil to suck into the PCV during boost. This eventually leaks down through the system and burns off in the exhaust.

Explains why so many different people with so many different setups experince the smoking. IE: Stock cars have it, modded cars have it.

Also explains why some people who have gotten their turbos covered under warranty end up with new turbos that still smoke.

Also explains why some people experience smoking IMMEDIATELY after a DP install, without even driving the car.

Research it some more if your more interested.
 
Its not the smoking im worried about.. Its as simple as this.. Replacing the downpipe im opening it up to a full 3 inchs.. even with a high flow cat theres still alot of freeflow and this means the turbo spools up faster and longer..eventually "overspooling". The over spool makes alot of friction and the turbo gets extrmemly hot which burns the seals! how hard is that to understand.. I dont think you would see a blown turbo from the downpipe immediatly anyway... I think it would take a couple of months to take its toll. If you think im wrong PLEASE correct me.(hand)

wrong there are several speeds with stock turbo, cia,tbe,bc,cdfp making 300wheel hp with no probs that about 350-360 crank hp

I really hope thats the case.. Im not trying to be stubborn or say this is what it is but I was on the phone with the tech at street unit and he said that they own a speed3 and run tests on the dyno all the time and hes saying that the downpipe is blowing the seals.. Im really aboutto call up MazdaUSA and ask if it will.. theyr'e the engineers.

Look online at some forums, stock 08 350z's can do 13.10s with the right driver, most guys are mid 13s easy.

I do think your wrong, and you are being stubborn. The stock turbos are not overspooling.

Has ANYONE overspooled a stock turbo yet?

By the way the stock turbo seals are metal rings, they're not overheating and causing leaking.....
 
ok

ummm, no, try again ;)

yeah,jokes.i love em'.especially the one about the ms3 (barely getting into the 13's at the dragway).i laugh at it all the time.most people run low 14's in the ms3(stock).here's the funniest thing about it.......i'm faster,with no turbo worries.but that's ok.no machine was built perfect.nice mods 2 your car.today i just got my cat taken off.when i hit the strip again(with my drag radials,i'll post my sub 13 second run.take care

Mazda will tell you adding anything aftermarket to your car could cause problems. They are not going to be much help.

IM NOT talking about stock 350z's and stock 37's.. My boys are into cars just like we arew and do work to there cars too.. fact of the matter is were turbo.. they arent and i wanna get the point across real well.. One of my friends has a 04 350.. stage 2 clutch and flywheel ,full exaust , and i think a tune... Thing is so torquyyy 120mph 6th to 5th rips so hard
