Last steps of greddy turbo install need help!

[turbo98_240sx]

does anyone have pictures of the greddy kit installed, or so way of telling me what they did with the vaccuume lines mostly with the fuel pressure regulator crap greddy ain't to clear and where do i tap the vaccuume lines for my boost gauge thanx. btw my e-mail is [email protected]

[red240ne]

You can tee-off of anything on the manifold. The fuel pressure regulator gives the best reading for a boost gauge. But I've found that most anything on the manifold works the same...

If you're wondering where the fuel pressure regulator is, it's on the back of the fuel rail. You will see the vacuum lines coming off of it.

I know what the fpr is but what is supposta get teed into it off of the c1 pipe (pipe right after the turbo) has a adapter to vaccume line dose that get teed into the fpr and the acuator? thanx

[red240ne]

I imagine they put that there for the wastegate

[turbo98_240sx]

isn't the acuator for the wastegate or am i confused?

[Joe]

the actuator still needs to see boost.

you should have a line that goes from the hot pipe, to the actuator, then to the wastegate.

[C-Kwik]

The actuator is pretty much part of the wastegate. It responds to boost and opens the wastegate flap as it reaches a set boost level. You can obtain a signal from any part that sees boost pressure. The turbo outlet and the manifold are the most common. Getting a signal from the manifold results in slightly quicker spool and for a given wastegate spring slightly more boost, but also contributes to a slight boost spoke and more heat into the intercooler. Obtaining a signal from the compressor outlet is safer, but spool will be slightly slower as the wastegate will creep open sooner.

BTW, was this the only connection you are stuck on or are there others?

[turbo98_240sx]

Yeah ok so this is what I'm thinking (the waste gate is internal so the actuator is what opens the waste gate) from the hot pipe there is a fitting that goes to the acutator but if your look at step 3-11 part 3 on http://www.greddy.com/prodimag...n.pdf that is where my probluem is see what gets hooked up to the fpr then because its gonna leave a system that don't make sence to me to tap the fpr because the acuator would have a pressure signal from the hot pipe. or is this to confusting maybe i'm making a mountin out of a mole hill but for some reason i don't undersatnd this oh yeah there is no bov on the kit so thank you for your paiciance i'm new to the turbo thing. and should i then put my boost gauge t fitting into where the vaccume line goes to the acuator?

[turbo98_240sx]

Oh yeah if anyone has the kit could you tell me what size studs were in the manifold that held in the turbo because i don't think i got the right size studs for some reason! They were 10mm*45mm yeah i got 5 of these and none of the 10mm*35mm studs that were supposta come with the kit or so the directions say. thanx

[turbo98_240sx]

so yeah greddy gave me the wrong studs something about overnighting them so yeah thats good that drove me crazy because turbo studs to big, anyways i hooked up the everything else but need to replace the fpr vaccume line because of cracking and should I just plug that hole in the pipe after the turbo (hot pipe i think) or leave it open? don't make sence to me but you's all the experts.

Pick one connection or the other. My prior post describes the effect of using each.

Secondly, please try to write out your posts as if you were turning this into a teacher to be graded. It makes it very difficult to read. Particularly since you are asking a technical question. This is not a chat room. Capitalizing the first letter of each sentence and using proper punctuation makes it much easier to read. There is a reason they teach English in schools.

C-kwik, Sorry I've been working alot and well I don't have much time. I'm not good at spelling to tell you that but I will try to lay out my thoughts in a slightly more understandable format. All that school stuff I don't ever use except at work, work makes me type stuff and it must be right and proper since the board has no spell checker there will still be some miss-types. Well I didn't mean to carry one with that I just wanted to Thank all of you for your input and I'll let you know what happens with the car.

Hey man I installed the Greddy Kit on my buddies 95 S14 a few months ago, we ran into the same problems you did. We had a problem with the exhaust studs that hold the turbo to the manifold, so we had to go to lowes and buy 4 more, i cant remember off the top of my head what size they are. We also had a problem with the intercooler piping, since we bought the intercooler kit. good luck with it, if you have any more questions post them up here.

So here is the deal, my car runs and sounds good but the boost gauge does not work (the gauge itself works but I don't have a way to connect it to a vaccume line yet.) The way I was doning it isn't air tight so it doesn't show anything. Tried it in several places and came to the conclusion that its the connection itself. Also the actuator does not seem to open at all when i rev up my car. Do you have to have a load on the wheels IE in gear driving to show boost, I didn't think it did but it would make some sence as to why i'm not seeing any boost on that gauge that I think works but no way to tell. So my question is what is the deal with the actuator shouldn't it start opening once I hit 5 grand on the tach? I'm gonna look at the boost gauge stuff tomarrow and post asap. thanx

[eyustfu]

get a T fitting for the boost gauge and hook it to the hose that connects from the FPR to the intake manifold

[turbo98_240sx]

I have the gauge with a t fitting on the hose that connects the fpr to the manifold and i never see any boost even when revved up so what is the deal? where could my mistake be? will it only show boost when driving (not when in netural?) or should it make boost even when the car is not moveing (on jack stands).

[eyustfu]

the car only boosts while driving

[:: orion ::]

The turbo typically needs a load to make boost...many small, OEM turbos will make a pound or to just by revving, but a properly sized turbo wil not show gauge pressure w/o driving.

K...

I hope you installed the vacume line from right after the turbo to the wastgate.

And I would T off the FPR vacume... and make sure to get small clamps to keep it from leaking...

You get no/little boost with no load. If your boost gauge shows vacume it does give boost... Just not enough to hit the + most the time.

Your wastgate should open at 6psi... not 5k... If you have the vacume line installed... If not it will boost to 12 psi...

Good luck...

[turbo98_240sx]

what if i have the acutator teed off the fpr insted of the hot pipe? is that bad? seems like i need a new clutch 60k miles on it and it will "slip" like I tapped the clutch and revv up and then it "grips" so time to get a new clutch i think unless someone knows otherwise? Ignore the 5k on the tach thing I wasn't thinking right. it was a dumb question, and thank you all I can't say how greatfull I am.:ylsuper

Also My check engine light is on what could cause this because it runs fine and i disconected the battery for an hour to reset the ecu with no results. Any input is A-ok with me because every little detail helps! Thanx

[turbo98_240sx]

car runs (hella good) although I'm addicted to the whooosh noise but then again isn't eveyone. So the clutch is fixed the old one had 0% of the pad on it. New ACT with a heavy duty pressure plate seems to fix that problem and gives my left leg a workout like it has never seen. The clattering of the clutch is a little annoying. The boost seems to lag a little more then i'm told it should full boost comes on at about 4.5k on the tach where sources tell me that is a little high and it should be seen at about 3.5k any reasons on this?

[Projex240]

mayeb the wastegate is leaking or something. You must ahve a leak--SOMEwhere.

[Red-KAT]

I hit 8psi at 2.5k-3.0k

But I have the E-01 installed so it clamps it down for quick boost.
