Ok, my integra is a manual and there is no way I can drive an auto its too boring, I have been driving a stick for three years and im not trying to say that Im an excellent driver or anything...well tell you what I'm going to go and test drive one today and Ill tell you what I think. Yeah I figured the S2k tranny would be a lot better than a Celica

 

I've missed a couple shifts in my S2k -- both at 9000rpm. I immediately felt something was wrong and floored the clutch before the engine wound up, so no harm done. Lesson learned.

Any stick can be over-revved if the driver isn't paying attention, and any high-compression engine will blow if you over-rev. Either learn how to drive a stick properly, or live with boring automatics. There is no gray area.

 

so spoon components won't help if you mis-shift...maybe I am asking this wrong how high can you take an S2000 w/ spoon parts?

 

that is bad. if you can't drive then don't risk trashing a $33k car. it's bad enough to destroy a $25k celica.

 

Perhaps we didn't understand your question. This engine has a rev limiter that works very well...it shuts the engine off at 9200RPM but only while you are accelerating normally! If you misshift and overrev the engine (this is a mechanical overrev) the fuel limiter cutoff will not prevent the overreving of the engine and you WILL ruin the engine, period! At this point the rev limiter will have shut off the fuel to the engine, BUT the momentum of the car and being in the wrong gear will mechanically overrev the engine and bend the valves, even though the rev limiter did it's job.

Simply put: if you misshift and put it in the wrong gear and cause the engine to overrev, #1) the engine will be damaged and #2) the warranty will not cover this.

I don't know how to put it any simpler than this.

See those little red lines on the right of the dash, that's called the red line . If you don't go beyond the red lines (around 9200 RPM), you should be fine.

 

Almost any engine worth having will be of the "interference" type, where overreving will cause the valves to hit the tops of the pistons and break or bend them. There is no way to idiot-proof a manual transmission. Rev limiters will protect you on the way up through the gears, but every downshift at any speed over the maximum for 1st gear is inherently dangerous, because if you miss the shift and for example get 1st when you want 3rd, or get 2nd when you want 4th, the mechanical connection between the rear wheels and the engine (through the axle, driveshaft, clutch and transmission) will force the engine to rev past whatever the limit is, and cause you to break your valves. If you don't trust yourself with a manual, buy something with an automatic (if you like choosing your gears, get a Steptronic or better yet, SMG), so this can't happen. Or, just be careful, and/or not downshift much. But the S2k shifter is about the best in the business, so if you can't drive one well, you can't drive anything with a stick.

 

He's asking what is the physical redline of the motor before valves start smashing into pistons.

My friend's dad used to drive a BMW 2002. He could easily take it past redline without worrying about immediate engine damage. Sure, doing that a lot will cause excessive wear and tear, but he didn't break anything on the inside. BMW was conservative with their redline.

How conservative is Honda's redline? The motor was built to rev, but how high? My bet is that the current redline is set so that the motor has some sort of long term reliability without exotic maintenance costs.

i can think of 1 non-interference engine worth having - Toyota 3SGTE

 

Amen.

redcel180,

Seriously... blew three engines in less than a year?? Blew one when runing away from cops?
Boy, you deserve to drive an automatic... No wonder toyota won't fix it... they already gave u
two engines..!!!
