1990

To be honest I dont know much about this stuff i am going to learn as I go its called autorotor from bell eng.

sweet i have a 90 as well and learned along the way and still am learning

well since you got a 90 you are going to wanna read this

and this

and finally this

the loctite fix can be done as a preventative measure, and if you are going with forced induction i would highly recommend it

i would do lots and lots and lots of reading before you stick the sc on there, just to make sure you know what you are doing

this is a new site the guys from miataturbo.net started this up a few days ago
so you can get some very good info from people on this site when questions do arise

and that loctite is an engineered fix. if it were me i would replace the crank nose bolt and perform the loctite fix and be sure to properly torque it shortly after getting the car

the motor is 20 years old u think its going to fail now? I guess I can look into it I will see when I go to install the SC but I have a feeling it wont be till snow falls unless my friends get real motavated.

shoot my motor is 20 yrs old too lol only 74k
i think that crank thing happens often after 125k.
it depends alot on if the bolt has ever been over torqued or not

alot of people have reported good luck with the loctite fix on broken cranks
therefore i personally would feel confident if i were to do it as a preventative measure

i havent dont it to mine yet and i probably wont do it til i pull the motor in a year maybe a little more, im replacing mine with a bigger one, at that time i will loctite my 1.6 and keep it as a spare motor

MINIMALLY if i were to go forced induction on my 1.6 i would replace and properly torque that bolt, but while you are doing that you may as well loctite it. at that point i would be very confident in that motor

that is the only major problem with our cars i can think of

good advice you have any idea what the rear end can take hp wise I read somewhere it was the weak point.

I also have a short nose crank in my car. Its FI (turbo) so no extra strain from the supercharger belt. I didnt loctite it. I did mine a little different as far as the key and key way are concerned. It had a damaged crankshaft key way. So I am trying this method and if it fails it fails. But curious to see if it holds up.

P.S. I drive the hell out of my car.

Ninja edit after seeing your post. Stock 1.6 rear ends can and will fail with stock power, ask me how I know. It depends on how you drive the car. If you are launching it, burnouts, donuts...etc will determine how long it holds up.

I'm getting old so I dont know about donuts but I do want to take it to the track I guess live and learn. breaking stuff is just a good excuse to upgrade anyways.

Youve never spun donuts before?!

this would be doing a donut...although its kind of a lame version. (not me)


and by track you mean, dragstrip?

no im hoping to get onto a road corse but i guess i can go to the strip to get powned how would i not know what a donut is ?
