K so a few of u know already I just picked up another miata for track duty and weekend cruising so it has 178k on the stock 1.6ltr and I don't know the history of the motor Cuz I got it from a older lady and she did not know crap...oil looked good cruising the oil pressure is about 40-45psi...at idle under 30psi and floor it goes up past 60psi so how long u guys think this motor would last autox before I do the lsx swap or a 1.8. Supercharged...thanks
With the information you have given us I estimate approximately 3 hours and 17 minutes if used for Autocross.
Good luck! ::Drive2::
Which works out to about 262.66 runs, or about 13 years of autocross. Of course it could die on the first run.Quote:

Timing belt, water pump, clutch, seals, belts, hoses, bushings, etc.
Or maybe just maybe check some of these items to give your self an idea of the condition of the engine. In no particular order!
- Run a compression check on the engine
- Run a leak down test on the engine
- Take it to a Dyno and see how it does
You can comare all those numbers to the orginal specification from Mazda to give yourself a baseline on where you are at currently
or
- Ask a bunch of folk you don't know on an internet forum to guess!
It's probably already dead or no longer competitive but I'll buy it from you for $100.
Friendly bunch around here!
Lol funny
I'd wager that it will run for more consecutive runs than the LS or 1.8SC frankenstein you're proposing. Engine swaps are notorious for bugs and gremlins. Just give in and buy the Lotus.
