Was injector bung question...now clutch question...

[Quattrospg at aol.com]

Thanks to all those who responded to my CIS to EFI injector question. I can't 
imagine how long it would have taken to find the right part # by trial and 
error...You guys rock!

Unfortunately, it seems I'll need a clutch before the EFI goes in. Was 
driving on the highway today, going up a hill I rolled into the throttle. When the 
boost came up to about 5 psi the clutch started to slip. Car seems OK on the 
flats and around town.... 

A few questions...

1. How long can I drive the car like this before the clutch goes completely? 
It apparently is the original one with approximately 220,000miles so I guess 
its due.
 
2. I'd like to put a heavier duty clutch in to handle the extra hp. Is there 
any benefit to installing one from a 5KT or is it the same as a 4KQ clutch? 
Other recommendations?

The car is an 87 4KQ with an MC top end and JT bottom end, so its still got 
the stock 4KQ clutch and flywheel.

Thanks (again) in advance.

Bill
