No Boost Checked Everything R33 Gtr

[Hot33r8723]

Won't build any boost there is no vacum to wastegates at all there is vacum on my boost gauge but boost just moves to zero cant hear the turbos spool what's going on here It's like I've blown a wheel of could turbos be seized

Untill you pull the dump pipes off to check the wheels are still there you havnt checked everything Go now.

Easier said then done To remove gtr dumps u need to take turbo's off.

[SiR_RB]

Check the front of ur cat converter for pieces of ceramic turbo wheels?

[R32GOJIRA]

I had a problem like this with mine a few years back where it wouldnt build boost.

It would register vaccum but as soon as i stepped on the loud pedal, it would go to zero and that was it.

Turned out the packing in my exhaust had shit itself and was blocking the flow of exhaust gases.

That may also be a possibility.

Drop the cat, give it a shake and see if any ceramic bits fall out.

[Tai1or Made]

Check for turbos.

Might be a NA.

Check if a cooler pipe has come off.

This is what broken turbine looks like;

[Hadouken]

I bet you cranked up the boost and still didnt get a tune

[Hot33r8723]

Nah didn't crank up the boost there is no boost

[Hadouken]

still no tune

[Hot33r8723]

There is no boost so I won't tune it till there is boost I don't no what the f**k is going on maybe wastegates stuck open

[Hadouken]

how long has it had no boost? when did it decide not to boost?

Did you go around the block again?

[AngryRB]

if the cat has collapsed it will not boost, take the intake pipe off and see if you can spin the compressor...

any odd noises? wonder if someone left a rag in the intercooler piping..

[Hot33r8723]

Yea the compressors spin fine it's the cat I reckon

[Tommy Kaira RL]

I had a blocked cat and I had no boost past 2psi. The cat still looked ok when I took it off. I replaced it with a highflow cat and that fixed the problem.

[iplen]

Yeah, mine got blocked with bits of ceramic turbine... Was very slow to come on boost Did it suddenly stop making boost while you were driving? Was there a pop when it happened?
