ok im just trying to get an estimate of how long they can last after they show the EARLY signs of going bad (i.e. after running awhile and getting hot mis stumble something odd.. no rpm climb anyway, or really hot completely backfire! i saw fire tonight =/) but anyway how much longer would yall say it has? (car just rolled over to 147k tonight)

also while im at it about the optis.. is it possible to put a 95+ vented opti ona 94 without changing anything? (already have a new 95+ elbow just have the hole for the vacuum plugged off as of now) but does anything else have to be done?

 

nope you've got to change timing cover, chain, and cam if you want to go with the 95 opti

 

O_O glad i asked... any idea about how long they "may" last after signs of it starting to go bad or is it a russian roulette type thing?

 

Here's what is required to change over to a '95 opti.

Could be the next mile or next thousand miles. At 147k, you are already on borrowed time. The opti is a wear item and does not last forever.

 

alright.. guess the opti is my next thing to do, everytime i try to do somethin else to my car it makes me change my plans lol last time i was gonna get headers trans went out.. this time i shortened the goal.. just get some good mufflers... opti said bye lol ah well by the time im done ill have a "new" car
