What different procedures does everyone use for breaking in a new engine? What types of fluids to use, and how long to keep that engine out of boost and/or under what RPM, etc?



Thanks for the info-

no boost or more than 4000rpm for 1000miles, then an oil change (and recheck) and its ready to go!

I used:

500 miles no boost nothing above 3500 rpm. oil change.

500 miles gradual pulls all throughout rpm's little to no boost. oil change. Set to go

How would you be able to turn the boost off if the car is bone stock?

put a rock under the gas pedal

breakin depends on what parts you are using..... whether its used or new housings, and what kind of seals you are using

These are my original, unscathed housings using 2mm Atkins seals. What kind of oil is everyone using for the break in time?

500 miles no boost then lay into it. I figure the seals have pretty much seated themselves by then. Change the oil at 1000k then 2000k there after.

for break in... .can you just put the car on blocks and let it rip?

That might be funny, but I've heard of it happening before.

When I was dealing with Pac Performance, a car went in for a new motor again, cause the guy put it up on bricks and stands and did it, but forgot all about it and the thing over heated and POP. Don't know at what RPM's.

"If its a reman most likely it has used rotors so the bearings won't need any break in. Drive it semi careful keeping the rpms below 7k for the first couple hundred and the boost below 10psi then change the oil and you should be good to go. When you change the oil dip your finger in the oil and you'll see why some break in is necessary. If the rotors are new you will need full break in: no boost and nothing over 4500 for 500 miles change the oil then light boost and nothing over 6500 for 500 change the oil and your done with break in." -- from fritz flynn on evil fourm ...

Okay, I'll ask it a second time. How do you turn off the boost if your car is bone stock? Take off the twins?

dont run above 3,500 ...

Oh okay. https://www.nopistons.com/forums/pub...IR#>/bigok.gif



I'm obviously still a n00b when it comes to RX7's and turbo's. So the twins don't spool past 3500?

boost doesn't hit on a stock motor that runs correctly before 3,200-3500 rpms, then secondaries come in giving it that 10-8-10 boost pattern that your car Should run at.

What did mazda say for a break in when the rx7s were new?

I've heard so many damn break in periods its unreal. Currently I am going to 2K miles w/o boost or revs beyond 4k since I put new bearings in my rebuild. I unhooked my w/g arm to keep out of boost, and its driving me nuts waiting to boost.

airflow problems? it might work if u can get a nice fan
