AT idle my boost gauge ticks. Went to an exhaust shop and noticed my cat was clogged. got a new pipe welded in and has a bit more power but i still put it to the floor and takes like 4 seconds to rev up higher. I hear a rattle from somewhere near the front, turbos spool up and sound fine and same with my wastegate. seems to backfire more than often. does it just need to be ran and cleared out more? please help thank you !

 

What mods?
Have you checked ignition, could be misfiring.

 

Timing, check your timing. Better yet check your two crank angle sensors on the top right corner of your main pully. They are notorious for breaking there mounting tabs and becoming misaligned.

 

i wish i could take a video and put it up on here. gonna start with plugs tommorow, took the cat out today and ran a bit better but still no power, in 5th i cant even get passed 60 mph

 

@ ryan dont have any mods except bov.. was running very very rich before tho. sounded like the start of a misfire, gonna change plugs tommorow see if that helps. @ duval ill ask my brother to have a look at that as well thanks guys. ANy other suggestions? im wondering howcome by boost guage is ticking at idol? and when im driving? when i downshit it backfires, boost guage doesnt tick when im coasting in a down shift but as soon as idol comes back it starts ticking? have i blown i turbo seal? how do i know?

 

Check map sensor hose/wiring.

 

is your handbrake on? I did that once...
seriously, I did.

 

No handbrake is not on.. i also am starting to hear more of a rattle now too. SPitting a lot of blue smoke when i rev it up.

 

how many kilometers on the motor?

 

90000, did i blow an apex seal? im worried most about my turbo gauge ticking.

 

Check the map sensor hose first of all.

Did this just happen out of the blue?

 

happened saturday i was boosting from 2nd to third around 5k rpm and just gave out and starting to bog and had no power. wheres the map sensor on these cars? hose/wiring?

 

right hand middle of the firewall, behind the throttle body/elbow

looks like this

 

what do i check for? if its broken? faulty? what

 

i think your options are:

1. hose to MAP sensor came off.
2. other misc vacuumn line/boost line has come off
3. blown apex seal.

jumping vacuum gauge is a bad thing...can you build any boost at all?

 

Just check to see if the little hose has come off the sensor.

I had pretty much the exact same thing happen to my car once. Was the hose to the MAP in my case.
EDIT: infact the hose to the MAP had popped off over near the throttle body i my case. It didnt disconnect from the sensor itself..

 

yes i can build boost, slowly but surely, blow off valve still goes off and i can also hear waste gate.

 

try changing your plugs. They could be fouling out.

 

The motor is toast. Same exact thing happened to me. Stop driving the car and get a compression test. In my case, I lost two apex seals on rear rotor and destroyed the rear housing. It also took out
My secondary turbo when a piece of seal went through it. The more you run the motor now, the more damage you are doing.

 

And I know what you mean about the boost gauge, it ticks and bounces.

 

This could be caused by a blown apex seal sure, because you're going to be missing 2 of your combustion pulses, but it could also be caused by any number of vacuum problems on a stock turbo car.

 

I completely agree, however, in this case I think it's pretty clear that he lost the rear rotor. Especially because he is mostly stock with 90k km on the motor.

Is the motor hard to start, more so than usual?

 

Yes it's harder. Ticks and bounces exactly

 

Sorry to break it to you but a compression test will confirm a blown motor. If you need a rebuild, contact Banzai Racing as they have some of the best prices and work around.
