R33 misfiring trying to hit boost

[AndreW_R32]

Yo!

 

so yesterday my s2 R33 rb25det was working perfect never had an issue. i get in my car i go for a drive i go to hit boost and its struggling, it sounds like i have a bee r limiter but no power at all just making mad pops from the exhaust. the factory boost gauge shows its working but yeah no power and it struggles real bad. 

 

i have checked all the piping and lines. no leaks or splits. 

if anyone has gone through this or knows how to fix it please help. i just wannnaaaaa hit boost

Spark or fuel.  One will be not working right.

 

 

Search.

idles fine, drives fine. just cant hit boost  

[AndreW_R32]

ill sus out sparks and fuel filter(old) and fuel pump 

[AndreW_R32]

update* i changed fuel filter. no more misfiring but still lags power. cant feel pressure when boost is on like its n/a

They are pretty slow standard.

[AndreW_R32]

its at 200kw and feels like 100. i just wanna figure it out before i do the g3 hypergear turbo setup.

Drop the exhaust.  Look in the cat for the turbine.  Then douse it in petrol and throw a match on it.

[AndreW_R32]

possible that the issue could be that the turbine has broken apart?

Check your coilpacks?

[AndreW_R32]

ill give em a check tomorrow. took it for a test drive and the turbo was glowing red hot af

What ECU? What boost pressure? What turbo?
Probably broken turbine.

[AndreW_R32]

stock ecu. 11.5psi. s2 r33 turbo. there is a paper in the car that its been tuned to 11.5psi. but doesnt feel like it. i changed the spark plugs seems to be working a little more better now. just gonna scope out for leaks with air compressor. i was hoping nothing shorted when i was using a light test and accidentally hit the smoke lighter and it sparked 

[niZmO_Man]

Stock ECU tuned? Eh?
Turn the boost down to 7 psi.
Wait, does it actually boost? Did you drop the cat?

[AndreW_R32]

hasnt been tuned for a few years. i have a dump and highflow cat and looked inside it no cermaic wheel bits. ive just put gasket maker for bov. tighten up everything else and install a boost a gauge tomorrow and see whats going on from there. its stopped misfiring. boosting better now. but feel like its lacking 10% of power i reckon but i'll let gasket dry over night and see how she goes in the morn.

Turn down the boost, your car isn't tuned.

You cannot tune the stock R33 ECU unless it has been remapped by Toshi or by those off the shelf remapped Nap ECUs (totally useless with Australia fuel and climate).

update* seems to be running better now. it ind of slacks but its getting there.

 

also i noticed after putting gasket maker for bov. when cold it kinds of flutters a little and makes a weird little metal noise after dose for under a sec. but once its warmed up it goes back to whoosh sound and no metal noise  

[AndreW_R32]

strange. now its starting to do it again.

 

so when i put my foot down as it gets around 4-5k mark it looses power even with my foot on the floor it doesnt wanna go anywhere. i try it again and boost will come on i try it again it wont want to move... so confused

Did you turn the boost down as suggested?
