Timing belt?

gabit · 04-08-2006, 10:46 PM

I'm getting a '91 NA supra with 113k miles that's, as far as I can tell, been babied. I also have a '91 MR2 Turbo with 250K miles (never babied!). I've never changed the MR2's TB (lucky?). I believe Toyota recomends changing the TB every 80k, but from my MR2 experience, I'm thinking "why rush?" ,I have to spend 1400USD for new leather seat covers. I'd appreciate the group's opinions. Thanks.

just because it is recommended does mean it has to be done. and actually i believe they recommend every 60,000 but the factory belt shouldnt have to be replaced till 120,000 miles. then again that is who you ask i guess. and nothing that bad will happen except it not strating then you get a new timing belt then it runs. anyways thats my oppinion

... unless it impacts with the valves when the belt goes. Seat covers fit your computer chair, ya think ?

don't forget, everyone is here to learn
and in some cases bent valves is possible, just not on supra engines

no need to be rude k

I love driving my Supra. I drive it every day. I love going for long drives, and trips in it. I can easily change the belt myself, AT HOME. I certainly would HATE having to PAY somebody else to replace a broken belt while I was on one of those trips, simply because I didn't care to maintain my car.

Not to mention that those long trips are on weekends, when shops are closed, and TOWING will be required.

I'll say no more, say no more. (hey, Monte Python Rules !!)

Ok as far as Im aware uk spec supras and us supras have the same engine in and according to autodata the supra engines turbo or not, 7mgte and 7mge are INTERFERENCE engines, so t belt going is bad news, however even if the data is wrong and in ten years of being a mechanic I've never found it to be. even if the valves and pistons dont have the chance to meet each other, If your doing motorway speeds when t belt failure occurs it can still cause damage just in other ways. The replacement intervalls are there for a reason, its part of looking after your car properly. If its the money side of it do it yourself Ill even send you the instructions!!!!!! just my opinion, MY other bit of advice is to change the tensioners as well as the belt!!!!!

not to sound like a bitch

but you may want to go and remove your t belt and turn your engine over 360 deg and you will find that pistons do not make contact with the valves
altho you aren't giving this information, autodata is.... nevertheless they are wrong

well I'll take your word for it seeing as youve rebuilt yours and Ive never had head off mine ( YET!!!). I'll remember that for next time one comes into the garage as well. Even so still would change the belt before its due though to save inconvienience and other damage.

Seat covers fit your computer chair, ya think ? __________________ So I bought this old Honda bike, an NSR250. Bit of a street racer, I guess. I'm told they're fast. Delivering it home with a friend driving the Supra for the first time. I drop gears and make a scream from the twin pipes flowing down this pony's flanks and it takes off like it's tail's on fire. I look back when the Honda gets to its tap-out and the Supra's only two lengths behind. No one I've let ride my bike has told me its slow, they've all loved the thing. That car is a good thing indeed.
