As always Will, I am humbled by your knowledge, but there is at least one visible difference of 92/93 and 94/95. The base thickness I mentioned. I know this because when I used my original bolts to mount the new SC, I had to put several washers on it to fill the gap.

I missed that post. Is it just that one corner that differs?

As far as I've seen, yes.

So just got back home, was in the beast and noticed the boost gauge was at idle in the zero and when i gave it gas it went towards +70, shut the car off and re started it maybe 20 min later and now it was idling -70 and when i gave it gas and the SC started whining it went to zero instead where it should go to +70 from zero. Weird. Belt is just an ordinary replacement belt the garage changed for my dad not long ago. The belt started shredidng and seperating. So its not a great strong aftermarket belt.

For sure gonna pop the pipe off and measure the size in mm. But the nose of the SC looks to be about 5" roughly.

Where can i buy all the parts for the coupler ? Also is there a write up on this? Im sure someone must have done a write up cause from what i searched through the board i noticed few people with the same clunking sounding SC'* lol.

The pulley doesnt wooble but more move around up and down like how a shaft would be in a turbocharger when u have shaft wooble. It does not spin in a perfect circle if u understand what im saying.

One last thing, how to check wastegate ? Probably take it to my buddies shop to have a look at for the wastegate.

Ok....you're canadian. Damn metric system.

Get an aftermarket boost gauge on there and see what it says in the same situation. If your pulley doesn't describe a perfect circle when it'* spinning, someone installed it wrong, which is why you shredded the belt.

I got your PM and it sounds at this point as if a full swap may be in order. I'd go ahead and replace the coupler in the 95 unit with a coupler from ZZPerformance.

You'll also need the SC outlet gasket, TB gasket for a 95 (yours won't work, and you should replace it), 2 yellow o-rings for the coolant passages in the lower intake, and the tube of gasket maker to re-seal the new SC nosedrive and rotor case after replacing the coupler. Don't forget the SC oil.

I suggest you thoroughly clean the 95 TB and SC as best you can before installation. The ZZP mini-afc controller will be required, as the readings from the 95 MAF won't be recognized by your PCM.

There'* a link to a photo galler on my website. On the 12th or 13th page of that, you'll see 2 scanned black and white documents. These will help you with the teardown/put back. They're for an M90 on a Series 2, but very similar.

I'm not sure about the fuel rail and injector differences between 92 and 95. Need someone else to chime in here.

This is my response to PM from Boosted, in case anyone else wants to read it.

You might want to replace the lower intake manifold gaskets, while you're in there. It'* fairly common for them to leak, and isn't too much more work. I wish I did, now mine need replaced.

You mentioned it has a 3" new exhaust. Did that include the catalytic converter? One of the symtoms of a bad cat is that the car will stall but then start rjight back up again.
Just a thought.

92/95 injectors are the same.

Hey Will, metric system rocks !! lol

That SC pulley was never removed since we had the car for about 3 or so years now.
The pulley has play in it when it spins , i dont know how to describe it. Maybe i'll make a video with my digi cam haha.

So short nose SC'* are the 92/93 ? Cause mine is the short nose. Going to check TB size tonight.


Mark,

it had a high flow cat installed also when the 3" DP back exhaust was installed.

92 through 95 had the short nose SC. It'* an M62, and Eaton put in Teflon coated rotors and a larger inlet, hence the larger throttle body, for 94/95
