so my friends turboed his hatch its a d16y7 it was all done correctly...but the thing is that it wont boost? its on 5 psi but we dnt feel any difference then stock...also when we hit luanch control like it read vaccum but it wont build boost so the gauge wont go over zero but ill read vacum just fine????dnt know wats wrong??? or could it be that its to low of boost?

ej8_fredi

anyone

really there has to be something not hooked up right or the wastegate is stuck open either way I would check the wastegate and check for leaks in the piping and intercooler. if you have pics of the setup we might be able to see something or point something out that you are missing.

ej8_fredi

we already checked the piping.....changed the intercooler and still nothing

lluks_844

maybe a coupler on the piping cam apart?
edit*nm beat me to it

ej8_fredi

i checked them all there all tight ......

turbojdmhatch

boost leak test it..... check the wastegate......really theres more than can be typed on what could be causing it....ebay wastegate or ebay kit?

ej8_fredi

idk its an XSPOWER turbo kit

JDM_Queen

Check your vacuum lines... Are they all hooked up right did any split? You could pressurize the piping and c if it leaks any where.

pretty sure thats an ebay kit....boost leak test it is where u should start

ej8_fredi

but i dnt got a boost leak tester lol

it has to be ur wastegate bro! i have a boosted D series myself right now and i had the same problem one point and i found out it was the wastegate ring... there is a ring in there that seals it where it meets the mani and if you have an external that is what it is... check that ring and flip it if you have it wrong

for low boost (if your wastegate spring is whatever psi and your wastegate looks like a tial 38mm) - plug a vacuum source into the bottom of the gate (yeah, the nipple closest to the flange on the bottom)

for medium boost (like double what your wastegate spring is supposed to hold) - unplug the gate

for high boost (don't recall, but I think it's double w/e your medium boost if I'm correct) - hook up a vacuum source to the top of the gate

so a vacuum source would be running a vacuum line off the nipple where your pcv valve is hooked up to on your intake manifold (Don't worry, your pcv valve is useless when it sees boost anyway, so just unplug it) to your wastegate (No "check" valve needed).

I had that same problem when I first boosted my car. I hooked the wastegate up wrong lol and never hit boost for about a couple hours, then I figured out why: I had run a vacuum line from the nipple on top of my throttle body into my wastegate. Little did I know, the nipple on the top of my throttle body was NOT a vacuum source.

I totally forgot about the ring in the bottom of the wastegate. I bet if you take it off and look at the valve seating you will see a gap. in your kit you should have gotten a small ring that is placed up under the valve to seal it. check that and let us know.

Are you going to spam every thread with your stupid new smilie? It's already getting annoying and you've only done it twice.

If you're not going to post something relevant don't post at all. OP has a legit question, and your post suggesting that this thread is dumb or annoying further proves my point that you're spamming.

Go away.

From what I've heard, and Ebay kit can work well, but you just gotta work the problems out, and prepare for potential ones. Good luck man

ej8_fredi

ill try that cuz like we took out the spring and it still didnt hit boost ...so ill check out the wastegate to if its the problem

BiggieBert

whats being use to tune it? How u controlling boost?


Edit* A tial/style wastegate should never see vacuum.

jasony0630

why would you take out the spring??

That would mean your wastegate would open when it sees any positive pressure....so no boost there.

and to BiggieBert, you plug a vacuum line into the wastegate so when it starts to boost, it will hold pressure. Pressure from the manifold going to the wastegate = boost.

wastegates that are functioning properly and plugged in will always see vacuum until the turbo spools up.

ej8_fredi

idk we checked out alot of things .....im tierd of this problem car.....i think were going to sell it...and get another civic

jasony0630

that won't solve your problem.

it just proves you're weak and dont deserve to modify a car.

if you took some pics we could prolly get it fixed in a couple minutes.

ej8_fredi

we have ran into a lot of problems like anything tht can go wrong goes wrong .... i can make a big list of tings that have gone wrong wit the car... how do i upload pics?

jasony0630

**** happens when you make an engine produce more power over stock. It's just a rule. No matter how well you build it, something always breaks. You gotta just deal with it.

Also, use photobucket.

ej8_fredi

like when we took off the oil pan there was a chunk of metal in there,when we put the y8 mani it leaked coolant,the wiring were the ecu was at was messed up and woulndt start,when we put the new clutch and lowered the engine the radiator broke,then the launch control would came on while driving,....lol.

jasony0630

how the [freak] did you land on such a [freak]ed up car?

goddamn....
