Warm up motor, disable sparkand fuel by disconnecting the crank angle sensor, hold throttle wide open, crank 4-5 times.

178 psi is factory

133 psi is the service limit.

This is on a 2g of course. 1g is different.

 

so remove spark plugs, then disconect crank angle sensor (this stops Fuel?)

Then crank motor under WOT 4-5 times...

sound like i understand?
cause i think i do,

 

I dunno... sounds good.

Just go try it.

 

what are the numbers for a 1st gen gst?

 

Service limit is 121.

Should be right around 150-160.

 

thanks
