this was a tough topic to search, and i only really came up with posts about cold weather starting issues and bigger injectors.


i live in the north east, so winter definitely sees temps below freezing and can often see temps close to zero. i also take frequent ski trips to new hampshire and vermont and see temps at or below freezing for 2 days at a time.

the question is, what effect would this have on a built motor?

i have never owned a car with aftermarket internals, and am possibly buying an evo with wiseco pistons and manley rods. now from my previous car knowledge i think that this may depend on the piston to wall clearances?

ive always owned factory turbo cars so i am very used to giving them time to warm up, and baby'ing them until up to temperature. but what else might need to be done/watched out for?

does anyone have any experience or input?

 

winters where im at usually dip into the 20's, teens, and sometimes single digits with wind chill. built motors usually yield heavier weight oils as well. (built motor here too, i had wiseco/hbeams last year, je/ibeams now)

start the car, let it warm to fully operating temps, then your good to go. if your going to drive it before its fully warm, give it a good several minutes of idling (i wait until its at least half way), then drive it real easy until the motor is fully warm. no boost until then!

 

keep in mind the viscocity of the oil you use.

 

Can you elaborate? Are you saying in terms of warm up time or for the internals. Or what?

 

It will be a daily driver also, and I only have a 10-15 minute commute if that. Nothing like doubling commute time to warm up the car

 

run a 0w 40

 

watch your boost spike in cold weather

 

im running a 10w40 through the winter up here, never seen anyone built motor run a 0w40

 

turbo'd engines LUV cold weather. You will notice a performance "upgrade" with the temps but like people said, let the turbo warm up before beating on it... still drive it to warm up just no start and pulls thats all. Good luck with the cold weather and if you think its the worst... just think of us up here in Winnipeg, Manitoba (yes...canada).

 

ill report back once i look at the car next week, i hoping the engine builder gave him a spec sheet so i know the PTW.

are forged pistons usually set any looser on the 4g63 than normal? or can you use close to factory?
