This is what i mean by how honda motors are strong.

very funny that u post this. One of my friends homeboy has an 04-05 type S.

He was racing my friend with the b20 EK, the type S redlined 3rd went for 4th and really went into 2nd and he popped his motor.
Acura said he hit 10K rpms or so for 9 tenths of a second. Not that stong.

I was shocked that it blew since it was stock.
I've over reved my car the exacty same way when i was stock going from 3rd to 2nd thinking it was 4th but my motor never popped... and I did it at least 2 times.

So dont thik they are all strong, probably just lucky.

The K-series engine's valve springs become inneficient at 9200 rpm because they start to hop, not because the engine itself cannot handle the rpms. High RPMs will not blow a K-series engine, but since it has interfirence heads it will bend a valve. The fix to this is very simple Crower/Spoon/Skunk2/Toda/Eibach valve springs. With these the rev limit can be set with the hondata computer to go as high as 12000 rpm without skipping a beat.

Eventhogh the rev limit is set at 8600 rpm, if you miss a gear it will spin the engine to high and cause this.

Again its not due to the engine being weak, it can withstand 450whp tuned with no problem, and there have been some to hold well into the 500 whp. The rods are forged, and the head breathes verry well. Hands down the best 4cyl motor out in the market now for the money.

Well, anything with aftermarket EMS can run well and raise the rev limiter. I was just shocked, i kno nothing about the motor really but I know it isnt weak. Being stock though I was like WTF.

Also why didnt the rev limiter stop this anyway?

[Mike R]

My d15b7 didn't see much high RPM and it blew up with only 157K on it...

[toucci]

The rev limiter can't stop the engine, it only keeps it from accelerating more under its own power. With the whole car's weight trying to spin it to a higher RPM there's nothing that can be done. Not really a big deal though since most people know how to drive, especially if they're trying to race.

Momentum. If you are going 80mph and are in 4th gear and the car is going 7500rpm, then you shift into 2nd instead of fith for example, the gear ratio is smaller and it will take the wheight of the car+speed+momentum and over rev the engine. The rev limiter is built into the ecu, but it can only stop what it has control over. It can stop you from over reving by cycling the injectors, or fuel cut. But it has no way of stopping what it has no control over.

What he should have done was immediatly press the clutch and put the car in neutral. Or just hold the clutch and let off the gas.

Another thing for him to avoid doing it again is to get a short shift kit and replace the rubber shift bushings with either poly, or metal. This will prevent mis shifts. Proteges also gain from doing this swap with Kartboy bushings.

Hmmm. Well, I don't think he'll be doing much racing with that. The stealership tried to rape him on the new Type-S engine so he got the regular RSX engine, and still paid alot.

He is gonna have to stick with the Tiburon v6.

I would have filed a complaint. Miss shifts happen especially whith close ratio trannys like in the RSX. Its a common mistake and this is the first time I have heard them not cover work. All the car needed was a new set of valves and off to the races he went again. Someone just made out with a perfectly good Type-S engine. The base is good to though. It takes to boost quite well as it has lower compression pistons. Tell him to go to www.cybernationmotorsports.com.
They will hook him up!

By the way NVMSP, I love the color of your ride!

He probably already paid and everything though. I thought cybernation closed.

And I'm not sure on the extent of the damge, he didnt say what was messed up and I didnt know this about the valves.

Thanks, it's the same color as yours.

['87 Turbo II]

haha my engine can redline for a long time. gotta love rotary engines, I've seen someone (about to get an engine swap who wanted to blow his old engine) take a naturally aspirated Rx-7 to 9.5k RPM for 8 minutes till he turned it off because his rear bumper caught on fire from the exhaust heat. I love no pistons. There was an old Rx-7 commercial in the early 90s that sayd "never blown a piston, never warped a rod, never detonated, live life rotary" Only problem is the low tourque.

[.mazda.speed.]

I saw that video with the 9000 rpm for 5 min. There was fire shooting out of the exaust for so long. I saw it on a website.

[smo0f]

yeah man, was just having a 30 mins conversation with my neighbors. redline on the rotoraries came up. pretty sick shit. i kinda miss my 1st gen gsl-se but at the same time it gave me too many troubles and wasn't suitable for a daily driver.

yeah the Rx7s eat money like a homesless man eats free food. It's ok, I doubt any 7 owner can previous or current can say that their 7 wasn't cool. Double negative, but you get it.

[Replica]

My d15b7 didn't see much high RPM and it blew up with only 157K on it...
I ran 11psi on my D15B7 and it ran for a little over a year and I shifted at fuel cut.

yeah man, maybe when i get some money together, after i get a house, i'll look into getting an FD as they have always been my favorite car

Hands down the best 4cyl motor out in the market now for the money.

Compared to what? Id say this is more preference than fact.


For example, mazda 1.8l BPs have ben known to hold 400HP on the stock internals and the motor was designed in the 80s. Cost $100-$600.


it can withstand 450whp tuned with no problem, and there have been some to hold well into the 500 whp

How much does a Type S motor cost again? it better fucking hold 450 lol how long did the 500WHP motor last? no way they are being driven daily at 500 and lasting.

[jeffmsp]

majority of mazda 4 cylinder motors + price difference of RSX Type S motor = K series pwnage any day of the week.

[ghost]

here we go again,lol. Yes jeff the MSP is god......... (deadhorse (first)

unsubscribed.....

[ghost]

oh before I go.... With the cash you spent on those ricy ass altezass you could get a course on engine building. I think Mazda is taking pointers from you.

[65racecoupe]

Nice ride, ghost. It looks really good. Power numbers?.....

Anyway, some idiot revving the hell out of his engine doesn't prove how "strong" it is.

You can't do that (spin that high) with a 302 Ford engine, but does that mean the 302 isn't as strong?

I would think that the strength of an engine has more to do with SAFE useable power potential.

[jeffmsp]

i would never put altezzas on a car. i work on a bunch of mazdaspeeds at my shop. see sig


Under the hood of a MazdaSpeed near you!


and then the different MSPs in the shop..pic 1 , 3, 4 are my car.

[Chilledboost]

11,000 rpm, that crazy shit. all that rpm and no torque. hondas upset me thats why i got rid of my integra

[jeffmsp]

and ya i know the argument is old. i think its the best honda motor out too, but if we where looking to go that route we would have bought a rsx. its way better stock for stock to a 4 banger mazda, and is approprietly priced higher. Doesnt mean the k series own the road or anything. sorta like the whole i can make a civic faster than a mustang for half the cash kinda thing but applied to the msp vs rsx. either way its not like your losing.

[nautical2086]

damn.
