im going to be doing a mild engine build with the vitara pistons and havent decided with rods yet but i do know that my block will be a z6...and when its all done do i need to breakin the engine b4 i actually start boosting?

 

You just need to go easy on it the first 500 miles, yes you can boost, just dont beat the living ---- out of it.

 

So many different methods to breaking in an engine....

My method that hasn't backfired yet:

Start the engine up and slowly rev up and down across the rpm's, but don't go over ~3500ish.

Turn off the engine and let it cool down COMPLETELY.

After engine is cooled down COMPLETELY, start it back up and let it warm up COMPLETELY. Bring it through the revs again.

Rape away. Change the oil.

Everybody will argue with different ways of doing it. Some people will say you need to baby it for like 50,000 miles and change the oil every stop light, but that's horseshit.

So 2 heating cycles and those rings are broken in/sealed nicely ready for boost eh?

Dr.Boost is now Dr.Flatrate :P

 

Yer damn skippy. :P

You're not one of those 50,000 mile break in guys are you? :P

I've heard of people raping motors after the first warm up. Some people swear by it.

You should see what I do to brand new cars with 3 miles on the odometer

On my personal cars I do go easy on them the first few hundred miles and change the oil after 500. You too would probably do the same after you spent 3000+ on a engine.

 

Bah, you and your damn B series motors.

I'm actually going to build a motor for my Civic. After thinking about it and knowing how dumb I am and how I have that dude in my head saying "Turn the ------- boost up you -----" I'm just going to start building something that will take an *** beating. I'm on a flatrate budget of $450.

I don't know about engine break in, but Jeff did teach me the proper break in after a turbo install... a big fatty burnout! I kinda did a ----- burnout though because I was running no fuel management and I was scared to blow my motor up.

 

after i had it warmed up i took it out go up and down in second gear, after like 10 times i raped the ---- out of it already. change the oil, then kept on raping. :P
runs very good and have no problem at all.

 

thanks for the input guys...
