as of now it has 280 crower cams, fidanza adjustable cam gears, aem intake, invidia exhaust, 1600cc deatchwerks, walboro 255......none of this is installed, all sitting on my pool table....but what else should be added to the party before they all go in?

 

evo 9 oem bov, full exhaust? if not test pipe and dp, lower ic pipes, tbolt clamps, WIDEBAND*** best investment, massive numbers with your set up!

 

i agree lower pipe is a must, full exhaust is a must, bov is a must if you want it to hold the boost pressure, and wideband if you want a safe tune.

 

what should i get to make it a full exhaust?

 

down pipe and test pipe no cat

 

any good turbo back exhaust system...... buschur is a good one. you want something thats full 3" with no neck downs so it doesnt restrict airflow. in a turbo equipt car you want the least back pressure as possible after the o2 housing

The stock exhaust system can you rob you 50whp or more. exhaust is critical when it comes to making power on turbo vehicles.

 

nah the stock setup is only 2-2.5" he needs the full exhaust system. if you dont have the catback portion changed i recommend you do it asap as well youll gain another 30whp easy.

 

only the catback is changed. so i need a downpipe and an o2 housing?

 

yes get o2 housing its important. you can get a megan o2 for cheap and works quite well. downpipe is very important as well. if you dont want to pull the o2 housing off just swap the downpipe out, the o2 will probably only rob you of about 10whp at the most.. and the o2 is a ***** to get off.

 

whats so difficult about it?

 

youll see once you attempt to remove it lol. the bolts are hard to get to if the turbos still on the car and they will most likely strip or snap off depending how you prep it before you go to remove them.
