i just got my fd about 2 months ago it is completely stock. i eventually want to make it a single turbo but i dont have all the $$ for that at this time i was wondering if i could get some feedback on what is a good way to start doing some mods that will not be usuless if i want to go single turbo one day.

 

You must install the safety mods first. These should be found by doing a search.

Larger all aluminum radiator, larger intercooler,
underdrive pulley, bigger fuel pump, Apexi Power FC ecu,
better ignition cables, ignition amplifier, larger secondary injectors, This alone will cost about $4500.
And your engine is still stock! And you probably will also need new clutch, $500.

Next a DP, MP or high flow cat, cat back.
This will be about $1000. Then when you go single, another $3500+.

Depending on engine mileage, a rebuilt block, $3000+.

 

Dont forger Fuel Pressure Regulator and Injectors

 

is a underdrive pulley really necessary?

.... what are the gains of new pullies? aren't they smaller? wouldnt you want bigger? Eh, i never really read up about them or their supposed gains?
help me out

 

A lot of mis information.

 

First thing you do is read, read alot. Read this. Once you think you've read enough, read some more.

 

small pullys = less cavitation at high rpm on the water pump, less parasitic drag due do less mass and slower rotations

 

almost every mod you do can set you up for single turbo, with the exception of an intake. start off with the reliablility mods (searching will show you). then go to upgraded programable ecu (power fc, haltech). then upgrade your fuel system. after you upgrade fuel, do cooling and airflow. you can do ignition right before the turbo or after the turbo kit, doesnt really matter, just depends what kind of boost you want to run. You can do mods in different order just make sure you have enough fuel to do the mods.
