What is the core size of the stock FD intercooler? and what is "generally" the max boost you can raise from the stock 10psi with this i/c and just a 3" exhaust.

I think the stock intake of the FD is pretty good, so I don't think I'd upgrade that til I went for a single turbo conversion.

 

stock is 11.5 x 4.5 x 2.5

I think it is good for stock boost some people run 12psi although this would be really pushing it.

P.S. what kinda 3 inch exhaust? straight pipe?

 

Pretty much straight pipe, custom all the way from the dump pipe, no cat, rear muffler.

 

how much boost are you running?

 

stock

 

then your fine

BTW: I'm assuming that your hitting 10psi at redline in 3rd and 4th right? or are you spiking?

 

nope just hitting stock boost.

What boost do the stock turbos max out at?

 

stock turbos can hit 15+psi although efficiency really seems to drops off after 15psi...

 

ahh, so next mod will be i/c (which will need to be sufficient for a big t04p or something in the future).

I'm amazed how well the stock airbox works.
