i need help installing my boost gauge .. from what ive read on the forum .. i just unplug the nipple on the uim and plug my boost gauge to that .. but according to the defi installation manual i cut the tube going from surge tank to fuel regulator and connect couple the tube .. thats great .. but for someone who knows jack about cars .. wheres the fuel regulator? pictures would be most helpful

spekdah

u sure its not a fuel pressure gauge?? a boost guage needs to read vacume not fuel i wouldve thought.
This seems pretty strange.
Surgetank???? you got a surge tank in yer FD??

hmm .. i dont have any idea .. thats the image for the boost gauge install that comes with the gauge .. anyways i just put it in the uim for now just to test my boost .. car idles at 16 hg .. seems to boost to 10 psi in 3rd at about 3k rpm .. i guess my other question would be .. how to read the gauge itself .. is it supposed to just jump to 10 psi and then drop? or if i were to drive at 3k rpm in third it stays at 10 psi?

I saw that you posted that your turbos were blown in an earlier post, why are you worrying about a boost gauge?

just hook it up to your manifold nipple. vacuum is vacuum, ya know what I mean.

What they're showing in the manual is the vacuum/boost reference to the fuel pressure regulator. They show that because EVERY car has a fuel pressure regulator, and that's guaranteed to be a good source of boost and vacuum for a proper signal to the gauge. Many other vacuum lines on the car will only show boost, or vacuum, etc.

Hook it straight up to the capped nipple on the upper intake manifold. That's a good full-range source and will give you a good reading. The vacuum line should just go straight from the Defi sensor to that nipple - no T's or anything needed.

well boost gauge would verify if my turbos are fucked? thats why im worried bout the boost gauge

dont hook it up to the fpr... doesnt work, i was confused too when I got my defi guage. Or you can splice it in with the stock boost sensor (by the drivers side firewall), Ive heard that it is more accutate, but I am yet to try it out.

Just get about 10ft of 1/4inch silicone tube and attach it to the nipple in the manifold. There is a small black cap on the intake manifold nipple located near passanger side. And then hook it up to your boost gauge. Remember to go with silicone hose because it has a higher heat capicity than the home depot hoses. I had problems melting and reading no boost with those hoses. Also lot of brass fittings are avilable at any hardware store.
Good luck.

Proper boost pattern is 10-8-10

Put the car into 3rd gear and go WOT from a 35 MPH roll, your boost should go up to 10 PSI at 2800 RPM, drop to 8 PSI at 4500 RPM(secondary turbo switching over) , at 4800 or so your boost should go back up to 10 PSI and hold till redline or go down a bit to 8 PSI .


FYI I hooked my boost gauge up to my MAP sensor, just used a T-Fitting, works great.

Who's Got Pics Of The Map Sensor Location. I Have The Boost Gauge And Want To Hook It Up There. Need Visual Help. I Have Fsm And I Hate The Diagrams. Drawn By A Five Year Old.

Look on the firewall driver's side. It should say "Boost Sensor".

sonix7

found it. where exactly should I tap off of the map sensor?

Skeltah

I just used a t-fitting and an extra couple inches of tubing to run from one side of the t back to the map sensor.
1.unplug tubing from map sensor.
2 plug top right of "T" fitting into the hose.
3. Plug another section of hose from other side of T fitting to MAP sensor.
4. Run hose from bottom of T fitting to boost gauge.

no.. not every car has a FPR...


Ford Escort's dont..

markemark

you wouldnt happen too have a pic of the capped off nipple???????

It's one of these two (I believe the top one). Please note, the UIM in this pic is how you'd see it if you were inside the car looking through the windshield. So if you're standing in front of the car looking back toward the engine bay, these nipples will be on your LEFT (the passenger side), not on the right as you see in the pic.

One of the nipples is used, and the other, instead of being metal like in this pic, will have a little black rubber cap on it. Just pull (or pry lol) the rubber cap off, run the boost hose to that nipple, ziptie it (or use one of the tiny clamps), and you're pretty much good to go.

Oh and if you're using a Defi gauge (like a D gauge), although showing boost is mechanical, the gauge itself functions electronically (the opening mode and illumination). So you'll need power, ground, and illumination sources as well to take full advantage of the gauge's functions.

Do you have a picture from another angel. The picture it's kindda dark I can't see that well. Soryy about that.

Forgive me here but anyone who has trouble with this or responds with answers like some I have read are in for a big surprise owning an FD. On the other hand its good for the economy. I don't normally post harshly but I feel for the guys who don't have a lot of automotive experience/knowledge. Really, it must end up costing a lot of hard earned money to iron out some situations.

You bastard lol. That pic is sooo clear! Unfortunately, that UIM is NOT from my car...it's from somewhere else on the forum, so I went and took some pics of the one on my car, w/ a boost gauge hose on the nipple (see the hose I'm holding):












You know, 9 times outta 10, you're right on this. But I was one of those 1 outta 10 ppl who had trouble w/ such basic things, but has come a LONG way, because I spend soo much time on the forum, and have such great friends to harrass about my 1001 stupid ?s haha. But yea...good luck guys. You're in for a REAL shocker, which usually ends up w/ ppl blowing the engine, turbos, or both, and just selling the car as is

Make sure you reload this page because I edited the pics, circling the nipple w/ the hose on it etc. If you don't see the bright red circle around the nipple in the pic, reload the webpage.

Guys I just put my car on the market I have a buyer who placed a deposit tonight. I then thought back on all I have experienced owning my FD. I just feel guilty selling the FD. Not just because I will miss it I have another project in the works but because the car can be so financially draining to its owner. I see the buyers and they are all young guys who just love the looks but they have no "real" idea what there in for. Maybe I am just soft in my old age. I can't help but feel for them. I really do.

I'm much younger than yourself, but I feel the same, having experienced what you just said. What can I say...when you grow up in a world of Hondas where you gotta try pretty damn hard to break stuff, you think a car is a rock solid machine...and then you see an FD, and become mesmerized by it. Throw in the fact that it's insanely fast, handles like a dream, and is a Japanese legend, you pretty much have everyone drooling, wishing they can own the car. Ppl simply don't know what they're getting into. It's not like the FD comes w/ a warning sticker on the visor about how expensive and difficult it is to maintain And the fact that buying prices have dropped so low doesn't help, either. I guess that's where the forum comes in...and it does a pretty good job of scaring away most potential buyers

damn fdnewbie, thats a thorough response, lots of pics and info- nicely done!!
