Even if you see no KR now, summer will be a totally different thing. If you see KR now, you're in for trouble in summer. What'* your fuel pressure?

You ABSOLUTELY cannot afford to go lean under boost, particularly with that pulley. You MUST check that fuel pressure before the pulley goes on the car, and you MUST scan for KR after the pulley swap, and as the weather warms up.

Like i said im getting a scan tool and ill check the fuel pressure, ill always keep an eye on thing once the scan tool is in my posesion, If i have tones of KR ill simply remove the pulley till i can get things fixed up to help battle it.

I know why you are stressing to my why its important to have a optimum running car and a scanner and I will be doing what you have suggested I know your basically running that same ca as me and you have been through all this before with it

and if all else fails and i cant lose the KR with the 2.2 them ill just have to break down and go a size up on the pulley to a 2.3 :(

Peter, I'm stressing it primarily because we're seeing ALOT of Series 1 L67'* with low fuel pressure and cracked exhaust manifolds. Age is bringing them out. Both are serious problems under high boost, and we don't want to see popped pistons.

I'd like to add...

The belt sizes Morty mentioned in the beginning of the thread may or may not be correct depending on the sizing of the pulleys.

If the idler makes up the correct amount of difference and those are the stock sized, great. The oversized pulley would be a must in that case or a smaller belt would be needed. The tensioner may appear to take up slack from a stock belt with smaller SC pulley and all other pullies stock...but as the belt stretches you would run into issues.

I run a stock belt and oversized tensioner (3.5"). I've never had any belt stretch issues. When fist installed, it looks close at the water pump, but clears it just fine. As the belt 'breaks in', you get the clearance you need.

A shorter belt on a Series 1 will not provide sufficient belt wrap to prevent belt slip on the SC pulley.
