Guest JAMIES DAD Posted June 23, 2007 Share Posted June 23, 2007 I have recently bought a 93 Jap import N/A Supra and would like to change the Cam Belt as I have no way of knowing how old it is. Can anyone advise me if I should just change the cam belt or if I should change the tensioner as well? Obviously cost is one issue I have to consider but I want to do the right thing.

Matt _Aero top_ Posted June 23, 2007 Share Posted June 23, 2007 Can you get uprated belts ? Quote Link to comment Share on other sites More sharing options...
Ric Posted June 23, 2007 Share Posted June 23, 2007 yes, HKS and Greddy also Powerhouse racing make uprated belts, all around 100quid. Quote Link to comment Share on other sites More sharing options...

silvershark44 Posted June 23, 2007 Share Posted June 23, 2007 I wouldnt bother with spending £100 on an uprated belt. The standard is perfectly fine. Those Greddy ones just look cool. I cant see the point running uprated even if your running big power, its not as if it goes any faster. Quote Link to comment Share on other sites More sharing options...
Guest JAMIES DAD Posted June 23, 2007 Share Posted June 23, 2007 Thanks for everyones input, I think I knew I should change the tensioners as well, just thought I would see what other people thought, think I will get standard belts from Toyota.

Scooter Posted June 23, 2007 Share Posted June 23, 2007 no rush in case you are worrying, as the belt snapping (something i've heard of once on here in 4+ yrs) won't cause any harm to the engine............ Quote Link to comment Share on other sites More sharing options...
Rob Posted June 23, 2007 Share Posted June 23, 2007 while you are there, replace the cam belt tensioner too yes. u can get the belt and tensioner for around 60quid Would you like to tell me where????? Belt was around £40 alone and the tnsioners was quoted at £90 from Toyota. Good job my tensioner was still OK at 200K. Quote Link to comment Share on other sites More sharing options...

tbourner Posted June 24, 2007 Share Posted June 24, 2007 Not on a non-interference engine like the Supe. Quote Link to comment Share on other sites More sharing options...
Matt _Aero top_ Posted June 24, 2007 Share Posted June 24, 2007 Hhmmm care to explain a little ???? stuggling to understand why Quote Link to comment Share on other sites More sharing options...
tbourner Posted June 24, 2007 Share Posted June 24, 2007 Bit of info here: http://www.familycar.com/CarCare/TimingBelt.htm 3rd paragraph. Basically the valves are situated far enough away from the piston at TDC that in the event that the cams stopped and the valves froze in position, the pistons would still not smack into them at high speed!!!!

Scooter Posted June 24, 2007 Share Posted June 24, 2007 Its as Trev has said....... basically in lots of engines the space the piston occupies in its stroke is shared with the space the valves occupy during theirs. The timing belt ensures they are never in the shared space at the same time! Snapped belt and its usual for them to come into contact causing often serious damage......... In the supra (and in fact most toyota/lexus) engine there is no 'shared' space so no contact is possible........... Quote Link to comment Share on other sites More sharing options...
