Sorry I didn't have time to search as thoroughly as I would like so sorry if this topic has been mentioned. I just couldn't find it in the first 3 pages and needed it asap to compare against.

So without further adeu, what is stock compression on a GS300

Thanks

 

10.5:1 Compression

Dumb is me I meant cyclinder numbers not overall : (

Like my supra is 171/171/171/171/170/171

 

ummm, each car is going to yield a different compression number due to age and wear. As long as the difference between them is not greater then 14 or so you should be okay. As long as it's not too high like over 185 or so and not too low like 110. Give it a shot and let us know what you get.

I thought compression on the motor was also 10.0:1
