So I understand that 4g63's are interference motors and a timing belt break will devastate everything. But has that ever happened to anyone here? If so at what mileage did it occur?

 

Change your belt at 60k and you will be alright. Breaking a timing belt doesn't happen often as the belt skipping cam gear teeth.

this is a maintenance thing you don't want to put off for later.

 

yup. i personally just hit 50k and my evo and ordered a belt last night. not takin n e chances. id say a stock one would prob break at 70k ish but don't even think about goin past 60 on stock

 

Would anyone recomend any aftermarket ones if a goal is 400whp? Or just keep with OEM?

 

id go aftermarket. something kevlar based. i just ordered the hks one. pricy but when it comes to and engine you don't want to start looking for cheap products

 

my car just hit 56K last week....it's already scheduled for the 60K maintenance...as others said, nothing smart about taking a chance and delaying it.

 

There is nothing at all wrong with the OEM belt.

 

Even when you start getting into higher hp? Mainly how much can it take?

OEM!

 

Im at 400whp and I'm good with OEM

 

Some people have had issues with the oil pump and chipping cam gears using Kevlar belts so its OEM for me. Sometimes spending more money may not necessarily be a good thing.

 

im putting down over 500 whp and i just replaced mine with an oem belt...

 

Back when the 4G63 first came to the US in 1990 all the OEM belts were bad. There was a recall. Some people responded and some ignored the recall. So, has a belt ever broken? Yeah, certainly hundreds but probably thousands.

 

i using greddy timing belt and there working fine for me they cost me a little but u get what u pay for
