Safely means: "You don't blow your engine when you are doing a WOT pass" It doesn't mean that it will last the same as if you let your engine stock.

If a STOCK Yaris engine was supposed to get 350,000 miles before a rebuild... a boosted Yaris will get there sooner.

How sooner? There is no straight answer. Depends on the maintenance, and mostly in how you drive your car.

Upgraded internals such as forged pistons and rods are not intended to increase longevity... Those are made to increase the engines ability to handle higher boost levels. Usually when you built an engine is because is going take some abuse... Longevity is not a major concern for people who spend the big bucks building an engine.

Realiability, longevity = STOCK

can't beat that.

we discovered that when we took out the pistons for ceramic coating last round. i promise i will take pictures and post it up when we crack open the engine for rebuild. recently ordered toga bearings from IPP, will take some time for the shipment to reach Malaysia.
