Rtech will smoke test for you if they think youve got a boost leak. 

Post the part number for your N75, i had to get a new one a while back and the part number has been updated.

Hi all ye I had a little accident in the car all sorted now and ye I thought you could have boost leaks but for the hassles I think the new pipes would be worth gettin I've put the new n75 valve on now and 007p just gotta put standard air box on shall I bother trying to smooth it Will it make much difference got the pipercross filter now also to slap in once box is on , or is it worth smoothing air box and instead of putting the standard plastic intake on making a bigger hole on air box and running a cold air feed to the airbox ? As I like the dump valve noise and surely putting standard intake on will get rid of noise :/ cheers all

Definately get a cold air feed to the airbox.....3" is nice size. 

R-tech is the way forward! without a doubt.  Its all about the graph and not peak powers. []

Hi buddy ye i am deffo going to use r-tech just wanna do everything to car first so will be running good im thinking weather to get a de-cat but not sure ever had one ? worth buying ? and also was told should buy all new boost hoses to ensure no leaks i had a dyno befor eand was 112 at wheels since then put new plugs new forge 007 or 008p dump valve will check new n75 valve .

regarding air intake system so you suggest standard air box with my piper cross panel filter and instead of stock plastic intake cut circle hole and put 3" intake down to near side grille ? cheers mate

[Chris.]

Yes for the air intake.

Downpipe is needed for good stage 2 custom results...it allows gases to get away quicker, allowing a quicker spool and a bit more torque.

Id go for:

Downpipe
Forge actuator (yellow spring)
007p (yellow spring)
pipercross in smoothed airbox with 3" cold air feed
Silicone TIP
Leak free boost pipe
Check your PCV system
and ensure your maf and N75 are healthy.
Oh and a good service with good oils and plugs, and a fuel filter.

Could push boat and go for a intank whalbro but that depends how weak your current pump is,

Hi buddy I rang r-tech today and spoke to someone as its currently only putting out 112bhp at the wheels i know stock is 150 but that's at flywheel ye so on average you lose around 33% I was told meaning ud loose 45hp which is about right however I personally think that's a lot to loose to much as for the parts u have mentioned where you say best to buy ?just want it to move a bit don't want to over do it n kill the turbo though , and how hard it to change an actuator on one ? And I recently changed n75 valve and maf sensor so should both be good as new , what's PVC mate ? When I bought it on about 106k did full service on 108 now so service kit still good on it cheers for your help mate
