I ran 8.7 to 1 CR pistons with a stock Starion turbo system and got that same light part throttle detonation. I found that the primary spring on the advance weights on the Starion distributor was super light allowing a lot of mechanical advance at a low RPM range.

By swapping in the springs from the carb motors distributor I was able to slow the advance curve so that I did not get the part throttle detonation.

Jamez: I run cheap gas myself. I don't think the Quest calls for premium. A assume the lower CR offsets.

I chalked the detonation up to a flat spot on my TPS. Yes, I did have the knock sensor connected and yes it was working. It takes about a minute for the normal timing maps to come back after it senses detonation.

Starion guys have been running 8.7 pistons for a good while now and I haven't heard much in the way of detonation complaints. You can run 8.7 on pump gas without problems. Personally, I wouldn't do it again without the oil squirters.



You are braver than I. Premium isn't required per se, but it is recommended for the Quests.

You crack me up. Damn I wish we were in the same area. Then I could bring over beers and hang out in your garage... <img src="/forums/images/graemlins/cheers.gif" alt="" />

I have a Mitsubishi Starion ESI-R that im selling it runs with a few problems. Note I didnt say minor problems, first off it needs a top end rebuild the 4th clyinders exaust valves are frozen. And the head gasket is blown. I bought the car back in september under the basis that it had this done but "it just needs a clutch and a battery" so i couldnt chk how accurate this was. However hard i may have been screwed isnt your problem. I just want a car that i can get running so i can go places. Im about 3k deep into this heep of *****. excuse my language, but after i got it running i found out it didnt have any work done to the top end. but im taking 1k obo for the car if you want pics i have them on myspace so hit me up ill send you a link. This would be a great parts car. with a fresh rebuilt turbo and other good parts in the car like mint interior except front seats and other misc parts are in superior shape compared to what ive seen.

i could make it to where you could drive the car home if you live close but i wouldnt try.


or call me at 678-571-1021 to see the half black have primer car that hauls ass eventho its broke.
