my friend keeps telling me i need a new engine because i have 115k on mine and its an 87...and he says its not fast and all this ****...(keep in mind he is 16 and does not have his license) so he has no actual car experience...but i dunno, is he right? would my power go down because the engine is getting up there? i mean i drive the thing. i can feel the damn power, i know im still within like in the 8 second range from 0-60 or somewhere near that...i can feel it, what do you think??

p.s. and would there be a difference in piston engine to mine? i mean would a piston engine or a rotary engine loose power more as it aged, or is it the same?

 

Compression test it. Low compression = low power. Near factory spec @ 120k miles is just as good as near factory sepc @ 20k miles.

 

ok so what do i need to compresion test it? do i need any special tools? anyone else have an opinion?

 

I think dr0x got it right

 

hahaha i think so too but how would i do that? i have no idea what i need to do that....

 

You would need a compression gauge or a trip to your local Mazda dealer.

 

go to the dealer you really need a special compression tester not just the piston engine one, gonna cost you if they have the tool in the first place my mechanic borrowed one from a freind at the dealer and had to fix the damn thing just to use it. sux

 

how much would the dealer charge for a compression check?
