Could be either boost leak, or I have seen this issue where cat was full of fuel.. Funny i know some customers do have em.

BR,

you will have a leak.  I had one from the charcoal cannister.  It will be in the inlet manifold.  Check every hose that it is connected.  (since then I am running 13psi without beeding at all)

i heard your car drive past a few weeks ago and you definitely have a boost leak, the thing sounded like my mums vaccum cleaner attached to the arse of our cat, Dina.

Roowwwhisssssssssss.

That would be your problem. Or it could be leaking between the exhust manifold and turbo but it didnt sound like there was an exahust leak.

I dont think cat would be your problem as i assume its one of those 'special high flow units' that mysteriously have nothing inside of them.

Sorry mate...if its never easy for the rest of us, what makes you think your so special???

 

:rofl:

 

 

Well....get cracking and take the muffler off, then tell us what ya find??

 

:rofl:

Fixed dudes ;)

Found the top intercooler pipe had somehow come lose... replaced one of the clamps and tightened it back up again and its pushing heaps of boost :) so i dropped it back to 10 psi cos i detected knock.....

Also I installed my PFC that Nengun finally got to me :rofl: and this car is now a total animal.. It was scary to drive so i put it away for tonight :rofl:

The best part is that i fixed the boost leak installed the PFC and got the car running awesome in just under 30 minutes.

In the back of my car you can see a Apexi PFC & HC box and right next to it you can see a Microtech LT12 with R33 adapter. What does that tell you ??? Let me tell you the car is totally different. it is heaps more driveable and does not stall or carry on like a woman... Its just ... no shit at least 300% better.

I dont know why ANYONE would go for the Microtech over the PFC as having to tune a Microtech with the wide band sensor was very hard.. it couldnt even hold the af ratios properly.. especially at idle.

So the moral to the story is.... Apexi Kicks ass :rofl: (IMHO)

Cannot find this boost leak.  My mechanic swears it being a exaust blockage in the mufler

Sould have been able to find a loose intercooler pipe..

One person sticks head in the engine bay while someone with the handbrake on put the car under load to bring on boost. Then you can hear exactly where all the air is getting out :P

I have had that problem, and it's amazing the difference with no leak.. as you said, it scares you when you hit boost for the first time.

I forgot to do up my Turbo to IC piping when I did my cam belt a couple of years ago..

Up on to 1bar of boost and BANG!!.. Did it scare the hell out of me...

Came to a halt on the side of the road cursing thinking I had majorly stuffed something as you could imagine.

Hey all

Guilt toy good work rb30det + PFC would be fun good fun

can you tell me more about you turbo set-up,I looked at rx7 turbo onto my rb30det but was advised on this forum that it would be futile

currently building a track car and have the rx7 turbo still ,i was hoping to fit it

is the turbo responsive from down low?

do you have a list of what you have done to your engine in buildup?

sorry for the bombardment of questions

cheers
