I got a 94, so it runs off a MAP sensor not an air flow meter, so it gets the air fuel mixture right still even with a boost leak so would be alright to keep going around the track. Would be under less stress then usual. Compression, vacuum and all are good. With the knock sensor and its fail safe mode in the MR2 it's pretty good at picking up any kind of issue and stopping any major damage.

Daon't agree with that but ok.
 
what were the comp numbers?

The concern was never really for the block as its just putting in less boost then normal. The concern would be for the turbo as its spinning unrestricted.
The cylinders were all about the same and reading around 160-165psi on the compression gauge. Vacuum is around the -20 off the boost gauge. The car still pulls hrd at partcial throttle its only WOT that was an issue.
Got some new ignition parts comming in from overseas as its much, much cheaper then australia, so should sort the missfire. Got 4 iridium plugs for $50 australia, leads for $50, cap for $30 and the button I bought here for $16.

Got the new sparkies, fixed the issues. No more hesitation and making full boost again.
 

glad it was such a simple thing..
cheers

Good result.
