S14/S15 Greddy Intercooler Kit Installation Manual

Hi Mates,

Does anyone have a softcopy of the above mentioned manual? Apparently, the vaccum hoses have been wrongly installed and i need to get them rectified.

Thanks in advance.

I don't have anything in softcopy but may be able to help. IIRC there is one vac hose that the Trust piping doesn't make an allowance for - so they recommend you to tee it off the vac source at the BOV

yea, the instructions tell you to tap into the carbon canister, this is because the they're S14 based, on the S14 they have 3 pipes off it, one of which is a boost feed. DO NOT Tee into the s15 one, doing this well create un-restricted boost!

you have to get a nipple welded/tapped into the hot side of the intercooler pipework, install it like it was as stock!

isn't it a boost feed you want? not a vac?! taking one from the BOV will work, but, it's a long way...... best to keep boost pipes as short as poss' so as not to spike.

i had to get a nipple welded into the hot pipe side on the intercoller piping, make sure you reuse the standard restricted boost hose or you will lose boost pressure

Thanks mate. Very helpful pointers indeed!

yes a boost signal is what you want and if you consider it, pre-throttlebody and post-TB will give you that boost signal you're after, a vacuum will not make a difference to the way the boost is controlled because if you're in vacuum, then there is no actual boost to control

you should also get the signal from the way it's set up from the factory - from the post-intercooler coldpipe. if you have an EBC then you can ditch the restrictor too
