Currently getting a new exedy heavy duty clutch installed, rear camber arms, and Rims are on the way in September.

Future modifications when my wallet isn't empty is deffinately a larger turbo, larger cooling pipes (are fair shitty at the moment and will need to be re-done eventually) and new front mount :)

Those FMIC pipes look plenty big as-is.. I wouldnt be changing those for anything larger, thats for sure.

Are you sure? the guy that installed the autronic (dont know if anyone here may know him, Chris.. speciallises in s15's and works in cromer) suggests going 3" if i want more power. as you can see there is weld marks through one of them, figured i may go bigger as well as well as have a more cleaner looking piping!

Feel free to throw out any suggestions

unless your planning on running a big turbo it wouldnt make much sense.

considering your using the standard T28 it'll take longer for the pipe to fill meaning more lag, cant see how you could make anymore power with larger piping.

looking at the dyno sheet and in agreeance with GOD (pipes big enough already) you might wanna try changing the hotpipe back to standard for a bit more response.

sorry i suck at explaining! my bad :) i mean't increase the piping to 3" when i get a larger turbo (sometime early next year)..

i dont even know if that will improve performance, or can i just put a larger turbo on it and leave the piping as is? I was going to get it re-done so the air filter wasnt shoved all the way down next to the intercooler (well its not visible) and move the battery to the boot...

keep in mind when all this happens ill be off my greens so less of a cop magnet, and my mate just got his engineering license. :)

2.5" hot side, 3" cold side is more than enough flow for 250rwkw +

Too big a pipe, and you get LOTS more lag (but no more top end). Keep it as-is :)

on the hot side you really dont want to go to much bigger than the outlet of the turbo, cold side can be as big as the throttle body, so yeh what the other guys said
