Intercooler pipe sizing and spool/ turbo efficiency
I have a question as well, I have a b6t Festiva with a rear mount setup.
2.25 exhaust back to the vj14/t bird hybrid, the turbo outlet is 2" and I have it stepped up to a 2.5 to the meter (which is stepped to a 3") then back down to a 2.5 which goes into the TB.
Now I'm curious as to if I went to 1 7/8 exhaust wrapped with heat wrap and 2" IC piping would it yield faster spool times? I currently get full boost at 4200 which I feel is a little late.
Discuss?

Yeah well there's one problem with keeping it up front there's no room for it 
I run AC in my Festiva and there's too much hassle with the compressor and condensor and water outlet routing to keep it up front.
Any other suggestions besides the one that is of no help?
