99% done with turbo kit (vac help)

[240sxinlv]

I have the following left to hook up before I turn the key for the first time...

Greddy Turbo Kit.

The following is what I need to hook up....Vac lines- Stock Fuel Pressure Regulator, Stock Manifold Fitting for FPR, Internal Wastegate, Nipple on compression pipe, Boost Gauge, and I have two 3-way tees.

Do I hook up the FPR to the stock manifold nipple and tee it off for the boost gauge? Hook up the wastegate to the nipple on the compression pipe?ORDoes the FPR need to tee off the compression pipe and wastegate?

Close but confused.

FPR needs to see vac. You should connect it to any of the lines behind the manifold, facing the fire wall, which have vaccum at idle.

Boost gauge can be tee'd off from same line as FPR.

Internal wastegate should NOT see vaccum. So connect it somewhere before the TB on the pipes.

both fpr and boost gauge (at least if it reads vacumm) need to see vacumm so the pipe wont work since it only sees boost (vac is read in the manifold after the tb). wg can receive its source from the pipe. greddy probably instructs to tee off fpr for the boost gauge, that may be fine, but i'd advise using the brake booster line, especially if you'll tee something else, like bov, off the same source.

If you are going to tee off the brake booster line, make sure to do it on the motor side of the check valve.

dont tee off the brake booster... just use one of the million other vacuum lines available, or rip off the intake manifold and rework all your vacuum lines. that's what i did and i got to eliminate a bunch of crap. there is a good tutorial on the stickies at the top of the kat forum... fiznat did the write up i believe...
