built motor in the winter?

[SPANISH-RICE]

alright heres the setup.
d16z6
wiseco coated pistons std. bore dished 8.5:1
eagle rods
acl bearings
arp headstuds
everything else doesnt really matter...

im wondering if im going to do damage to my motor if i break it in over the winter? i know that forged pistons expand diffrently than the block and im wondering if thats going to cause problems becuase of the looser clearances they need. I heard that wisecos are really bad for noise when they are cold also. i had piston slap on my last motor when it was 80 degrees out until the motor warmed up and i dont want to go to start it in -10 below and knock the thing apart.

So my questions are:

• is this setup winter safe?

• is there pistons that i could run a little bit tighter clearance on?

• what clearances would you suggest to run for about 350 whp when boosted?

• where do you suggest for machine work? i went to m&j last time and i had some mean slap when the motor was finished. it might not be their fault but ive heard others have had the same problem.

• will the coating on the pistons help or does that act as insulation from the cylinder wall. the wiseco website just says if done incorrectly can anneal the piston or something it doesnt really say what it does.

• is a block heater going to help at all? i already have one

I drove my Integra around for a winter w/ JE 9:1 pistons and a pretty healthy piston/wall clearance and it sounded like a diesel when it was cold. After that it was perfectly fine. I got over 4 years out of that setup...

who do you have do your machine work?

a thread about just machine shops for motors would be a good sticky

That would be a great sticky.......... does Quality Engine & machine do much on four cylinders?

[LoveMachine69]

According to my research there is a high possibility that you are a ricer

[ticklemedaly]

quality is by far the best shop to have machine work done at. i have heard nothing but compliments on their work. as for specs, it maybe best for you to check out other civic d16 forums to see what they have experienced. nicks b is a similar design for the era but still different.

Yup I have had great stuff come back from there, mostly v-8 race engines but wasn't sure if they did four cylinders

quality did my work. it was a 4-cylinder if you get it in before the start race motors which i believe they start very soon they also have good turn around time.

ya they do 4 cylinders. it shouldn't matter what things a machine shop does (except for some exotic things i can understand) as long as they have the equipment and specs/tools.

Breaking the motor in during the coldest of cold months is definetly not the ideal in a perfect world. But if you can't wait I don't know man, it should be ok, just make sure EVERYTHING is up to proper operating temps before doing anything I guess. Especially going to upper revs or boosting a good amount. A fair amount of loading is going to help you seat the rings once everything is warmed up so you don't have to be a wuss, just don't blow your load enjoying all the groovy goodness right away I guess. Quality does good work from what I hear, and my old man used to have cranks balanced there, never heard a bad word from him about them and he's anal as all hell about that shit. Just remember any machine shop does as good of work as you demand from them, hopefully without messing up your crap first or charging you your first born. Good luck sounds like a sick build

why build a motor in the winter?

[GarageAlchemist]

i could see building one in the winter, but not breaking it in

what else am i going to do during the winter? i cant race, so i figure i will have alot more time to pay attention to the little things and just make sure its done right. i think winter is an ideal time to BUILD a motor, but i agree with heath about breaking it in. im a little nervous.

My motor was machined and assembled by Payn Technologies in MI the first time around. This last time it was honed and assembled by me and Nate.

As far as break in, fuck that. Get it on the dyno after you realize it doesn't have any leaks and let her buck.
