i was reading a post last night, and all i took away from it was that the slightest upgrade to my car without porting my waste gate, will only lead to blowing up my engine.
i drive a jdm t2 swap, all im looking to do at the moment is get the RB rev t2 exhaust for the moment.
can anybody clarify this please.

 

your car will blow up without proper fuel and fuel management upgrades. Not wastegate, but it helps when you look into turning up the boost.

Look into a fuel cut defender or ecu upgrade.

 

ive already got a walbro 255 for the turbo engine, and i was planning on buying a the RB fuel cut defender with it and maybe rtek when i have the money, and every other small kink worked out...

 

Keep on Gaining info while you are searching for parts for the old Beast.
The Fuel cut defender is good for when you open up the Exhaust(go bigger).Also porting the wastegate.
The Mods you can do are sort of limitless,and stops when your wallet is empty,so "think smart" and you can make the car pretty reliable and have fun too.
If you can keep the boost down until you can find out what the Consequences of NOT having certain parts on to assure that the engine won't Blow on ya,would be a good thing.
..as they say,,it is all in the tuning.(and a little info on how **** operates can't hurt ya either!!!!..hahha!)
Cheers and Good luck..Rotor on!.STYX!~

 

the FCD will only allow you to overboost the engine and blow it up faster. Always port the wastegate before upgrading any part of the exhaust if you don't have the means to run larger injectors for the increased boost pressure.

 

Boost will be a lot easier to control if you have a cat, especially if you have an s5 turbo.

 

LOL at telling him to get an FCD. Fuel cut is there to help you NOT blow your engine up. Port the wastegate first, a great time would be when you are installing your new exhaust. It's not that hard and you could take it to a machine shop to do it if you feel inadequate. It also gets you very intimate with how the turbo system functions.

 

At least the OP is asking questions and wanting to take the right steps (I didnt the first time around). Get yourself a boost gauge and a wideband. The wideband will tell you whats going.

 

a REV TII exhaust will give you boostcreep on a stock wastegate.
Thats why the FCD is there. Seeing as how we all want more performance out of our cars you can get a FCD but only after porting the wastegate if your exhaust is not stock.

 

Everyone is talking about raising boost and no one has mentioned cleaning or upgrading injectors? Not sure what they are flowing but its probably not as much as it should be. Although a walbro will over run the stock fpr so you might be ok for a while.

Ideally one would port the wg first, then get exhaust. If more boost is desired a boost controller should be installed in conjunction w/ an fcd (which is in NO WAY a safety device) and cleaned or new injectors. A wide band would be nice, but at 10 or so psi, not really necessary.

Common band aids that seem to work include;
A walbro 255 on stock injectors/ fpr....raises fuel psi
Aftermarket fpr on stock injectors....raises fuel psi (limited by the stock pump)
Gsl-se 680cc injectors in secondary position....runs rich, but provides a safety margin
