i discovered that there are some visible signs of wear and tear to my crank and rod bearings after boosting the engine for about a year+.

Who said Yaris was slow?

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. |

some people do enough abuse to their oil after 1 weekend, some can go 3-4 weekends + daily driving before they "need" to change. it really depends on the setup and oil analysis is a very cheap and good idea, especially if they have a baseline of your car pre-boost. :) Quote:
good idea is to build it for 250 more horsepower then you plan to have. :) |

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.

What to look for in these pictures? I'm no expert.

There's some pitting there that shouldn't be.

was boosting 9 psi and yeah i do push the car very hard most of the time, often lingering at the red line limit.
well nevertheless the bearings would have to be replaced. hopefully the Toga bearings I purchased from IPP will perform. i wasn't able to locate a part number for our 1NZ from ACL and Clevite. if anyone here manages to do so appreciate if you could share. alright, i'll try to snap pictures of the crank as well, was thinking to keep the stock crank pulley though.
