///BHRpowered Posted January 16, 2008 Author Report Share Posted January 16, 2008 My wife's engine blew and it was a 2.3. bhr will strongly assure you it was due to not taking it to the dealer you would think so, except for one little detail that no one could save.

///BHRpowered Posted January 16, 2008 Author Report Share Posted January 16, 2008 look its simple, I have been going over millenia's for sale every single day for the last 2 motnhs, everywhere I look there are 2.5's with blown engines or trannies, those are the parts cars, they are the ones shot, and all have under 160k, I have yet to find a single S with a blown engine, only 1 with a bad tranny (more like just fluid, and it had 250k) and the only 2.3 parts cars are the ones that have been crashed Link to comment Share on other sites More sharing options...
mattlau89 Posted January 16, 2008 Report Share Posted January 16, 2008 ill make sure my car go's past 160k haha even though my tranny did blow on its own.. Thank god mazda paid for it since we were such loyal costumers. the dealer actually told us if they didnt fix it for free they would give us a mazda 3 but yea mazda trannys just arnt good.

mohamedeladawy@hotmail.com Posted January 16, 2008 Report Share Posted January 16, 2008 all i know is that my car passed 300,000 (and yes im still in contact with the owner and it has now 310,000 miles on it) it's still running well. he had to replace the water pump and change the tranny fluid but that was it. still running beautifully.

enginph Posted January 16, 2008 Report Share Posted January 16, 2008 How many miles on it whe you bought? Link to comment Share on other sites More sharing options...
Renboy Posted January 16, 2008 Report Share Posted January 16, 2008 BHR, your theory is still flawed. Hers never saw the dealership, that's true, but I highly doubt (actually I know for a fact) that hers wasn't the only one that never saw a dealership. Do you honestly believe that hers was the only one that wasn't serviced/repaired at a dealership? Since other milly's are on the road that haven't been to a dealer, then that would suggest the dealership has nothing to do with reliability. The 'L' is cheaper than the 'S', broke assed hobo's don't take care of cars, unmaintained cars are less reliable. Therefore cheaper = unreliable. That makes more sense than dealership serviced.

///BHRpowered Posted January 16, 2008 Author Report Share Posted January 16, 2008 ren, the L isn't that much cheaper then the S. and what about people who buy clearly crappy cars and don't do shit to them all I'm saying is searching any for sale sextion you can find blown 2.5's anytime, anywhere, and all with low mileage, if it was 200-250k I wouldn't care, but 120k, come on Link to comment Share on other sites More sharing options...
mattlau89 Posted January 16, 2008 Report Share Posted January 16, 2008 its almost a 3k difference. if i had to choose i would take like P and put a turbo charger on it haha Link to comment Share on other sites More sharing options...
enginph Posted January 16, 2008 Report Share Posted January 16, 2008 The efficiency of the MCE with it's open valves during the beginning of the intake stroke might put less stress on the bottom end of the engine compared to the 2.5. So if 2.5s die from engine damage that might explain it. G. Thats a good reasoning. Actually i was regretting about why i didnt go with a less problematic 2.5L when i first bought the S as reading all the s/c issues. Looking at the overall engine including s/c 2.5L is by far more reliable. What causes an engine to blow? oil starvation? Link to comment Share on other sites More sharing options...
enginph Posted January 16, 2008 Report Share Posted January 16, 2008 What is bore and stroke? I know the physical meanings but what would happen if you change the ratio keeping the displacement constant? There should be some optimum ratio for better combustion front or something..

ing-schu@online.no Posted January 16, 2008 Report Share Posted January 16, 2008 In general longer stroke will give more torque on lower revs, at the cost of ability to rev. The KL (and KJ) are shortstroke engines at 75,5 mm, which in the 2,5 is taken advantage of with a high redline of 7 or 7,5 k depending of version. And the 2,5 does have rather low torque for its capasity; it was constructed before variable cam timing became common technology. And variable timing is often used to achieve better torque on lower revs, giving a wider spread of power. The Mazda 6 2,0 is a good example; variable valvetiming in the facelift model may have given only 5 hp more and give or take same maximum torque. But the torque on lower revs is vastly improved, and makes the car a whole lot faster in real life, read everyday driving on lower revs. The stroke is 83,1 or somethng, which means bore is bigger than stroke in that one too; rather shortstroke. The previous 2,0 has over 90 mm stroke, a typical longstroke slugger configuration with fairly impressive midrange. A few millimetres difference may sound insignificant, but tells a whole lot about an engine. Anyone having driven both engines (previous 2,0 compared to 2,5) will agree that the fun just begins in the 2,5 where the 2,0 will do a better job on the next cog. Read 5 k.

///BHRpowered Posted January 16, 2008 Author Report Share Posted January 16, 2008 when new in 95 there was almost a 5-7k difference, however, in the aftermarket I haven't noticed any difference in price really Link to comment Share on other sites More sharing options...
Renboy Posted January 17, 2008 Report Share Posted January 17, 2008 That's because the price of the 'S' dropped to the 'L' level due to it's pos s/c and people's expectations of failure. Stroke=torque, and bore=hp. Longer strokes pose more engine problems than bigger bores. With a longer stroke you need a taller block, which adds weight, you also get more torque, which means you have to beef up other parts (tranny) to cope. Not to mention longer strokes lead to piston and cylinder wall damage because of the bigger angle between the rod and the piston/wall. And as Xedos pointed out, they're rpm restricted. With longer strokes piston speeds become an issue. Link to comment Share on other sites More sharing options...
///BHRpowered Posted January 17, 2008 Author Report Share Posted January 17, 2008 yet they never happened, I have seen very few S/C failures, and 90% of them can be traced to poor owner maintaince, where as the 2.5....well, I just think its 2 much work to move all that weight Link to comment Share on other sites More sharing options...
Troutman Posted January 18, 2008 Report Share Posted January 18, 2008 L transmission woes can be blamed on maintenance as well, with the right effort put in they should go a decent distance. Link to comment Share on other sites More sharing options...
Renboy Posted January 18, 2008 Report Share Posted January 18, 2008 Let's see, my wife's failed, MTS's failed, and MillerTime's failed (technically twice). I've only met two people from the site and all 3 of us had failures. Apparantly your math skills are as refined as your grammar. Link to comment Share on other sites More sharing options...

///BHRpowered Posted January 18, 2008 Author Report Share Posted January 18, 2008 ren, for the last god damn time, search ANY for sale section, you will find blown 2.5, major engine problems, and also, the problems your talking about are the s/c, not the internals and care of the engines. and what happened to mts Link to comment Share on other sites More sharing options...
