Hey we'll i want to go boost and i am not familiar with a turbo kit at all. I've gone all motor and it doesn't seem that full filling. So my question would be if i were to throw in some low compression piston, would i have to put that in first and drive it for 2000 + miles and break the pistons in before throwing the turbo kit on, or can i throw in the low comp. piston in and slap on the turbo at the same time and just slowly drive it until it all breaks in? Also, what is all of your opinion on how big should i bore and sleeve my b18c1 block?

Thanks for your input

 

I know alot of guys that break there motors in without the turbo on. BTW you dont gotta go 2000 miles. search around Rocket had a nice write up on breaking in a motor.

 

2000 mile break in? a couple hundred mile is plenty to seat the rings. just put the turbo on and stay out of boost. i know on my SRT4 the factory recommended 300 mile break in with a few WOT pulls during that period.

 

Some people say that driving with low comp. piston will make your car stall very bad. Is this true? Also, doesn't haynes man. recommend driving nicely 500 miles then do an oil change and drive an additional 1500 miles to break in pistons?

 

I logged compression test results from my motor break in for the first 3,000 miles. 80% of the highest compression numbers were achieved at mile 500. The last 20% took another 500 miles. I think a few hundred miles is adequate for ring seal.

 

I rebuilt my engine, held the RPMs around 2,000 for 10 minutes, changed the oil, then floored it out of my driveway.
