hey!, i gave my car a bit of shit around a corner today and i lost boost halfway around it???

now i get no boost at all!

i no the turbo was on its way out (smoking and squeeling etc)

could this be the intercooler piping? i tryed to look for leaks but didnt see anything or is the turbo just dead?

mods: rb25, micro tec, 3 inch turbo bk,fimic, 040, ebc etc 10 psi

cheers dylan

Jesss where do we start...

so you have no power/boost when you drive now... What about any noises that were not there before???

have you looked over the little vac line that goes to the actuator on the turbo and made sure it has not just popped off???

if intercooler piping pops off you'd know about it as the car would run like a dog on 2 legs in a greyhound race...

how much smoke you blowing? did the smoke increase now that the car does not make power???

Not true.

He is running a Microtech, therefore, will have no AFM. Check the intercooler piping (including the pipe straight off the turbo and also into the plenum), that is the most likley cause.

in my old s15 a part of the turbo-dumppipe gasket was deteriorating, and a piece got jammed in the turbo exhaust wheel, was giving same as above, no boost car reved like a n/a car. but it was obvious the gasket was gone from the noise it made. when i replaced the gasket, and removed the gasket piece from the turbo wheel everything back to normal with full boost etc.

probably should take the turbo off anyway and have a look

Worst case scenario, you have a leaking gasket or a crack piston ring land.

Once the turbo is taken out check the turbo and the exhaust manifold bolts. Sometimes bolts can come loose.

If everything looks good. Do a compression test and check for oil leaks.

      Took a little trip  went to nismo hoping the get my fuel tank hoses and unfortunately they told me they didn’t have stock luckily I was able to go to a Nissan parts store and they were able to order them in for me  then can home and cleaned the tank with some degreaser and fitted the new hoses before putting it back in the car

      100% I’ll hack into the 33. Strap a turbo onto the RB25DE and/or put the 25 head on a 30 block. 33 passed in cos the reserve was too high. I’ll try lowballing it again and negotiate. Aim is to have it landed and on the road for under 15k, then spend the same amount on top in mods.

      It's generally best practise to run 1x run without VCT enabled, then 1x run enabled till redline. Overlay the two torque graphs and you'll find the desired RPM to turn off VCT. Sometimes, it might be even worthwhile turning off VCT earlier control torque/cylinder pressure and using VCT purely to spool the turbo.

      First time I ever have issues with Amazon, but my wife often tells me to keep an eye out for fakes. It finally got me. I wrapped up the conversation with Gates. The gentlemen I was talking to seemed to hate his job but the response time on their technical support is outstanding. He stated that the hose is marked with some variation of "SAE J30R10" but that if you only purchase a 1 foot length like I did, it is possible to get a cut between markings and have a blank hose. To no ones surprise, he stated the swelling and "gummyness" isn't normal and to replace/buy from somewhere else (He mentioned NAPA). I'll toss a small end of the new one in gas for a few days before pulling the hanger out again, just to be safe.  Hose should arrive Monday. For those running multiple pump in tank hangers, you know the joys of getting them out and back in. I'm surprised I haven't destroyed my level float yet.  Lastly once I wrap all of this up, I'm planning on hitting the dyno again in 2 weeks while I'm on vacation. I realized recently that my VCT is set to turn off at 5000RPM. I'm surprised it wasn't increased while I was on the dyno last. I'm expecting I can increase it to ~6500RPM, if not more. Should hopefully get another 15-20kw out of it. I also want him to revisit my knock thresholds. I'm occasionally getting false knock around 3000rpm.
