So i just finished putting my turbo kit on and i test drove it and i dont hear thr turbo spooling til around 5000 rpms. But its weak boost. Heres my exact setup and some things that i think my be effecting it not making boost.

D16z6 full engine
t3t04e turbo 57 trim
drag turbo mani
ebay wastegate with 8lb spring
2.5" down pipe
450cc dsm injectors with resister box
2.5" intercooler ping with a 3" pipe from the throttle body to bov
stage one exedy clutch
ebay boost controller. Manual.

so here are some things that i might think why im not producing boost.

- i have an exhaust leak come from where the wastegate sits on the manifold.
- my turbo is a 4 bolt but i only have 3 bolts holding it to the mani.( i know sketchy)
- my down pipe is a 5 bolt but only 3 is holding it to the turbo.
- ihave my bov. Boost gauge and boost controller all t'd to my fpr.
- i have my boost gauge turned all the way down
- or maybe one of my ic clamps isnt clamped down tight enough

Those are all the things i can think of. So if any stick out as an obvious reason please let me know thanks for the help!

 

1- you're missing the sealing ring in your wastegate
2- put all 4 bolts in your turbo to manifold


any exhaust leaks PRE- turbo will cause major boost lag

3- fix all your mickey moused crap before you regret it down the road.

 

Ok thanks man. Will fix in the morning. Ill post the resualts

 

is it even tuned?- theres no mention of tuning software of any kind in your parts list, nor having it tuned... honestly it sounds like you rushed into this man, be careful or you will pop that motor in a hurry...

 

Its not tuned yet but. I have my ecu base maped on crome

 

sorry for the noob question but is the sealing ring a small ring that comes with the wastegate? And does it go iin the bottom of the wastgate?

 

Yes without that fire ring your dumping exhaust gas used to spool the turbo right out the wastegate.

That base map is used to start your car to get it to a tuner, nothing else.

 

loose clamp on the charge pipe would make lag/no spool. boost test it or check to make sure they are all tight. also any exhaust leak pre turbo as another member mentioned above, the bov could be leaking boost also or the cheap wastegate

 

Thanks for the advice ppl. About to go work on it now. How would i check if the bov is leaking boost?

 

is this thread serious? you're missing several key bolts AND the sealing ring on your wastegate, and you're wondering if there is a leak slowing down your spool?

seriously, how is it that every day people come on here asking what's wrong with their car, and it's the most obvious answer in the world.. I realize we're all learning here, but c'mon, really?

 

Chill out man everyones gotta learn somehow ha. Anyways i didnt know what that ring was for i just thought it was a spacer or something. But i just put it in and it fixed that problem. ANd i dont have the 4th bolt to my turbo cause i lost it somewhere in the process lol. so gonna get another one from the hardware store. But i didnt think that on bolt would effect the boost that much.

 

QFT

 

lol i realize people need to learn, i put up some dumb threads myself. it just seems like lately some of the people on here are staring straight at the sun and then asking why their eyes hurt, and this thread is right there with those.

 

So i just finished putting my turbo kit on and i test drove it and i hear the turbo spooling til around 3000 or 4000 rpms. But its weak boost. only 1#
i have CXracing turbo kit new westga ring is on gasket redont it clouper cheq
need help please any one know anything let me know thanks

miguel.

 

people have told you what the problem is, you're loosing pressure and there are more than a few places it sounds like you could be

 

get a vacuum block for the bov, boost controller, and gauge. and stop driving your car without having it tuned. I hope u didn't get a made in china turbo.

 

welcome to the new Honda-Tech

 

put the 4th bolt in the manifold and watch the problem dissapear. you do have a gasket between the manifold to turbo and manifold to head right? u wouldn believe how a small exhaust leak will cause **** like this. i had a tiny crack in a manifold and boost went from 20psi to 8

 

yea but i unbolt the screws and replace the gasket put silicone and nothing

 

so .. on the bottom of your wastegate. you have the metal ring in there ? its a sealing ring for the valve. about 1/4 tall and 1.75 round.

 

 

yes have the metal ring in there
i have p28 ecu already done for LS but not for turbo do you thing that is the problem
i am get in crazy with this man

 

Wantboost that pic of the dude shaking his head made my boring *** day at work a whole lot funnier!!

 

m7 cruz. with the ENGINE OFF ( yea i put that in bold)

see if your turbo compressor wheel spins freely without bind and not hitting the compressor housing.

if you see bright silver around where your wheel is and the housing. good indication your turbo wheel hits your housing ( evident of a pos turbo)
