To break in hard or not to break in hard.

[JoshCrane1]

Much debate has been had over whether it is better to break your new engine in the way you will always drive it, or to baby it like they recommend in the manual. I could understand not redlining it for the first 1 or 2 hundred miles, but baby all the way to 1000 miles, come on. Also i was talking to my buddy toyota mechanic and he said that every engine is not the same new ( obviously). But that every engine has a baseline give or take 10 hp off the assembly line, that seems like a lot of tolerance. that could make a difference in a stock vs stock race, wouldnt you think, anyone have some 1/4 mile times stock consistent?, dont forget to mention how many miles you had, for debating sake.

i babied mine all the way to 1500 (under 3k rpm) and when i had the turbo i kept it under 3k rpm again for 500 miles.

i don't get why you're all about 1/4 mile times with the tC. its not a fast car and its not meant to be a fast car either

Thanks for the input, and to answer your question, the term "fast" is relative. And 1/4 mile times are a benchmark for which to base your cars speed on. My car is fast, compared to a civic, but to a cobra, no my car is not fast.

k u copied my post. any reason?

I disagree - the tC was meant to be built. The stock internals can handle up to 18psi at 6500rpms all day.

I'd love to hear what cars you think are "meant to be fast."

And if the tC wasn't meant to be fast, why'd you turbo it?

i'd love to see any tc with stock internals at 18 psi at 6500 rpms as a daily driver.

cars meant to be fast = wrx, sti, evo, srt4, etc....

i turbo'd it to give myself a little more bc i missed my old sti, increase the mpg and to offset all the shit i put in the car

[bottled]

the tc is not meant to be a race car... its not meant to leave stock either..... the car was designed with the consumer in mind.... therfore it is what you make it and if you make it fast thats good.... but if you bought it to be the fastest car on the block you gotta alot of work and it would just be easier to buy a different car.....NOT to mention probably cheaper.... like an srt4 for the money owns our cars... somthing about stock on slicks runs a 13.5 quarter.... for us to run that we got to find away to throw 100 extra horse into our engine safley..... so IT IS WHAT YOU MAKE..... just make a smart investment and you wont be dissapointed

Pretty simple really....Vipers, Corvettes, some of the Mustangs, Saleens, Ferrari's, STI's. I would not consider a Civic, or a tC to be associated with fast. They are sporty looking cars, and economical but they are also heavy, and not really that easy to tune once you do add F/I.

Just curious as to what internals you are referring to that can handle 18psi and 6500rpms all day?


and I boosted mine so I could get the BOV........LOL!

[Nebster]

when the manufaturers ads on the tv talk about style and about the community its not about speed. where as ads for mustangs sti's, evo's, srt 4's etc... talk about speed. then you know it was made for performance.

and to run 18 psi at 6500 rpm you have to dump a pretty penny into the engine. but if you wanna run that first please let me know how many seconds you can run your car. and i'm not talking about down the strip i'm talking about how many physical seconds your car will run at 18 psi and 6500 rpm with a stock block

It's not a lot of work to just add a turbo kit to your car. That is what Dodge did with the Neon ...AkA SRT-4.

If you just wanted that pooosh when you shift, you couldve done it a lot cheeper, with a air compressor.:toast:

[THansenite]

like an srt4 for the money owns our cars... somthing about stock on slicks runs a 13.5 quarter

But look at the price difference comparing a tC to a neon. If you bought a stock SRT....I can't say it....its still just a neon haha :razz: and a stock tC, take the money you saved buy buying the tC and put it into a turbo, you could walk the neon for the same total price.

And there isn't that much of a difference in horsepower straight off the assembly line. It is actually closer to 5-7 horsepower. As far as breaking in the engine, I drove it nice for the first couple hundred miles, then I slowly worked my way up the RPM band. 51,000 miles later, the car still runs like a champ :up:

ok enough break in already get the turbo!! LOL

[Stryker Trailwood]

i drove it normally, and a tech over here drove his around the texas motor speedway for 3 laps during his break in, said its as good as any way to do it, i dunno, i just drove it like i needed too and then the same way after the supercharger

[2dot4]

You should always break in the engine slowly - the idea of breaking in the engine in to slowly "temper" the internals and pumps and whatnot. If you buy it with 2 miles and take it to the track, or slap a turbo and nitrous on it the day after you buy it, you're probably going to warp a piston ring or bend a valve or something. You have to get the engine up to speed by "Seasoning" the pistons and fuel system. That's why you break it in slowly. It only take a couple hundred miles though and you're fine. Guaranteed it'll add 50,000+ to the life of the motor.

As for SRT-4s, you're all retarded. When they first came out, they were $19995, and had an inferior fuel system. So by 2005, they upgraded the fuel system, tweaked a few things and changed the price to $24995. Now I might be wrong (doubt it), but paying $25000 for a neon with a pussy turbo kit (hitting 230hp) on it seems like a waste of money. Not to mention, the SRT-4 also has a 2.4L (sound familiar, tC owners?). It's built like a neon, and it still falls apart like a neon. Plus, the car looks pathetic - it's got bubble headlights and a whale fin. WATCH OUT!

You can pay $25000 for a 230hp neon, or you can buy a $17500 tC, turbo it for $2200 and pay $19700 for a better looking, more reliable, faster car.

The WRX is the same way - nice attempt, but since they fucked up the body style, they can keep their 227hp monstrosity.

As far as my options - the tC is the best one, and I wouldn't trade it in for anything.

[J3ST3R]

Alot of how or how much to break in an engine depends on the intenals being used. For example Forged Pistons require a little more cycling because of the expanding and contracting properties of the material used, where as say a Hypereutectic piston does not require the same cycling because of the materials used, which happens to be the addition of Silicon. If you watch how some of the Exotics get testing its pretty straight forward they take them on the test track and then maybe a street drive. The engine that we just built for my used all forged components so we made sure we heat cycled the engine/components several times, then basically ran it with some cheap oil for 50 miles, changed the oil, then ran it for 500miles changed the oil, and then ran it for up to around 1000 miles before I started letting it see any decent rpms. Also during this time I varied the rpms to make sure the rings seated properly

[THansenite]

ok enough break in already get the turbo!! LOL


I dunno man, do you think 51k is enough breaking in or do I need to baby it a bit longer before the turbo? :razz:

[2dot4]

ha! I turbo'd my car within 3 weeks of taking her home. Took the car home on May 3rd, installed the turbo May 24th (in under 5 hours! :trophy:).

750 miles of N/A is enough for me - time to burn those piston rings! I'm gonna swap em out anyway. lol

[SyntheticDivision]

I dont even have a turbo and you can still beat alot of the rice that flying around.


I thought break in was only 600...whats what the dealership told me

[1*BA*RStC07]

Ok back to the original post... the "break-in"- cars are made waaaaaaaay better today than they were 30 years ago. The rumor still flys around about "break-in" periods bc way back when engines were built with a lot of slop in them... and for those of you who baby it, there's no problem with that. But just so you know, the factory runs your engine at redline for 15-20 min before it's put in your car. My friend bought an X-runner in 06 and the second day he had it (with barely 100 miles on it) I was driving it bc he thought his clutch felt wierd, and beings it was his first Toyota, I decided to show him what Variable Valve Timing was all about. (The Silverado SS had to learn the hard way). The truck still runs that same way it did when he bought it, no harm done. Even my tC kept up with his friend's X-runner and actually nudged away in third gear lol :dance: so they're not turds. It's just a Camry engine slapped into a smaller car, so they are pretty quick for what they are. And by the way, ditto on the gay-ass Neon. I went to school with a kid who had an SRT-4 and he defended it to the end saying "It doesn't say Neon anywhere on the car," but it still is just a Mopar (Monday Order Parts And Replace). :boohoo:

[2dot4]

I have yet to meet an SRT-4 owner who's not a self-righteous, cocky asshole. They're fast, yay! But they're built like shit and you'll have it in the service department more often than on the road.

I had my first tC for a year and a half and took it in once to fix a dash rattle that turns out was caused by a shitty reinstallation of my gauge cluster after a blue LED swap. No powertrain problems, no other interior problems. My brother had 30,000 miles on his neon and cracked the torque converter (and the service guy told him he warped his flywheel too....on an automatic. :crazy: but it didn't matter since it was under warranty). but for a torque converter to crack on a 130hp neon? That's some shitty manufacturing.

I'll never buy an SRT-4 for the simple fact that Ive already built a faster car for less money, and I know my tC won't fall apart.

[JoshCrane1]

Hate neons,even though i never knew one of those assholes driving by, they always drive like assholes, im thinkin they have to justify there ugly car by driving fast or something, whatever. Those things are deathtraps, got rear ended by one at a stoplight in my thunderbird, lets just say he wasnt driving away, indefinitely. But hey, sacrifice safety and quality for a little bit more speed, go ahead and knock yourself out, literally. oh yeah, did i mention he was traveling only 35 mph, i knew because my friend was behind him.;-)

[dirtyred]

screw break in. i was doing 105 with 46 miles on the odometer, redlined through every gear. 10 hour road trips. traded it with 16000 miles on it. was getting 26/29mpg. no problems ever.

[Nebster]

some people want to run our cars more than 16k :)

[dirtyred]

of course they do.

[toeveryhour]

Just suck it up and do the break in. It'll be better on your car in the long run.

Patience is a virtue.

[amdforever]

I wish I knew more about break ins when I got my tC...def. would have driven it nicer to say the least. Right off the lot she hit red line, doing 80+. My job is like 100 miles away on open road...she was in cruise control 80mph every day. Now I'm worried for her sake, but hey, I'm planning on building the motor anyway so w/e. Question though. My car buddy knows a lot of shit about engines and drivetrains, he said the main reason they say the vary RPMs for the first 1k or so is so that the cams dont wear to a certain profile. Is that really true? And if so is that b/c they aren't heat cycled enough so the metal is softer and just wears the profile on them? B/c I have a a/t and at about 80 it sits at 3.2k RPMs and coincidentally enough, from my I/E/H setup thats when the car really starts pulling and makes more power...but the manufacturers of the products claim thats when you will see the raise in performance anyway. So do I have any need to be concerned?

[1*BA*RStC07]

AAHHHHH!!! there is no break-in!! Call your local Toyota rep and ask them what the "break-in" period is and they'll laugh and you and tell you to just drive it like you normally would. :wallb:

[HammeredRooster]

The dealer never said anything about a break in period when I bought mine. The only thing is in the owners manual and it says not to "race" the engine for the first 1000 miles. I read that about 2 days after showing my friends what my tC could do on the road and i had about 300 miles on it. now i am up to 9k and no problems yet. WAIT...one minor issue. Sometimes when i am driving through a dip or pulling into my driveway, I can hear the sunroof shift a little as the car flexes. No engine issues though...

[JoshCrane1]

yeah that sunroof shit is annoying, but hey its not a beamer.
