Camry & Solara LoungeDiscussion area for every generation of Toyota's family car, the Toyota Camry. Lexus ES250/300 owners welcome! Topics of discussion range from fuel economy, safety, modifications, performance and more.
I'm sure this has already been covered, but I couldn't think of what to search for. The torque I get from my motor is satisfactory, but I just don't have any high end horsepower. I'm tired of having to floor it to get around people on the highway, and even then it takes me nearly 10 seconds just to go from 80 to 90 mph or so. Would it help to clean out my intake and throttle body? I guess the three obvious solutions would be a turbo, s/c and nitrous. However, I can't afford a turbo or SC system, and nitrous is not something I would want to use on the street. Is there anything else I can do to increase horsepower at higher speeds?
Oil was changed about a thousand miles ago. Spark plugs, I don't know. I've only owned the car for about the last 9k miles, but who knows how long it had been before then since they were changed? I probably ought to chane them anyhow...what should I get? And would it help to buy new spark plug wires? The old ones aren't really "old", per se, but I see all this stuff about "performance" spark plug wires. And if I have to change the spark plugs, I might as well clean the intake out. Oh yeah, are there any tutorials on changing spark plugs?
^^^actually it is pretty decent, the reason u have to floor it is because of the (my guess) auto trans. Try putting the etc (ect wutever the hell it is) on and it will learn ur driving patterns better and shift much more readily along with slightly adding power and reving higher. Or disconnect the batt for like 2 minutes and reconnect and it will relearn ur driving patterns. Try turning off ur O/D when u want to pass, it only will prevent the trans from downshifting to conserve gas.
As for getting more power, do some simple things, ie intake exhaust, advance ur timing a bit and get some higher end sparks ie iridium (however u spell it), expensive and dont last as long but ull notice a bit of a diff. for sure. doing those easy things ull beable to squeeze sum xtra horsies outta the 1mz. If u really want get a custom y-pipe made,,,,ull really notice a diff ther throught the entire power band and ur MPG should improve quite a bit, the 3vz and 1mz's y-pipes are very undersized in my opinion
thers tunzz of other innovative ways to add power, try doing a search
Wait, what? I knew it was distributorless ignition..but...wtf? Explain. There are still wires going from the spark plugs to...somewhere. And maybe the 1mz should have good passing power, but mine doesn't...it's quite frustrating actually, in fact I don't notice much difference from a 4-cyl 00 cam I drove a while ago. I kinda get paranoid when driving on two lane highways, because I don't want to hit anything since it takes me a while to pass.
Unless you have something major leage wrong, are used to way faster cars, and you're over-exaggerating, 1mz-fe's have a top end almost that of a nissan vq30.
Aaaaanyways. Build a straight back 2" id collector 2 1/2" merge y-pipe, or have one built for you. Also have a performance cat put on if you can afford it at the same time.
10-15, if the cat is way dead, maybe 20whp is nothing to scoff at.
That's the dead cheapest performance you'll get without any major modification.

^^^i dont know wut ur smokin man but ther is a BIG diff between the pull in a 4 cyl and v-6 camry, ther must be black smoke comin from ur 1mz-fe if its THAT slow...and as for the spark plugs....ther coils, in other words distributorless, in other words electronically controlled, in other words better, in other words ever so slightly more power. The wires go to a computer controlled unit (i assume, i dont have a 1mz to look at)
Well, I was referring to in town driving, not out on the highway, I didn't get the chance to take it out on the highway. So I don't know what it's like flooring the 4-cylinder, in fact I probably shouldn't have even mentioned it. And no, I'm not used to way faster cars, really the only other vehicles I have driven extensively are my dad's Ford Five Hundred, and his former vehicle, an '97 5.0L Explorer. The 500 is only slightly better, but definitely the Explorer would get up and go. Of course there is a 2L difference there. I don't know what that nissan is lik, but all I'm saying is I'd like more power (who doesn't). Anyhow...I will look into getting a y-pipe made...how much does that generally run? I wouldn't have any idea how to make it myself, and I can't weld, so I'd just have it done. Oh yeah what's up with that intake air temperature sensor thing (s-15 or whatever it is)? Probably all hype and no performance, but has anyone actually tried it?
I can see a knock sensor problem with Ranger's car... usually when the knock sensors get too sensitive or malfunctions, it pulls timing and the engine lacks power big time.
For the '95-up 1MZ-FE, they are DIS, but wasted spark. Three coil packs directly sit on top of the spark plug for the front bank, and 3 spark plug wires goes from the front coil packs to the back (rear bank are not COP). So yes, the Gen4 1MZ-FE do have spark plug wires, although I doubt they ever need replacing.

Most shops will do it for $250-$350. Normally $300-$350usd because it's a complete bitch. You can try and intake and cat-back exhaust. I never recommend them first... A y-pipe by itself will give more power for the same cost.

after installing my cat-back exhaust (apexi WS) i did notice more top-end power. while I was under my car installing it I got a great look at one of the ugliest y-pipe designs ever. the exhaust gases from the rear bank have to make almost a 180 degree turn into the flex pipe, then squeeze through a flattened section of tubing right before the cat. i really want a new y-pipe made but the cost and project difficulty is turning me off. Toysrme, what are those dyno sheets representing?

Well, as far as the intake goes I have an SRI installed already. About the knock thing...I do have quite a bit of engine knock, and I'm running 89 octane (just out of high school, I'm poor and unemployed, okay? ). I'd say that my car would top out around 100, 105 at the most. Today when I was passing I had it nearly floored, going 90, and it didn't feel like it would pull much more than that, but I didn't want to push it. It has a lot of pull below, say, 60 mph, but above that it's not so hot. So if the knock sensors are truly bad, what can I do? Or are they really bad at all...since I do have the engine knock. About the dyno sheets, I think they're both from a 1mz right? But the bottom one is from the older 1mz, with the 6 coil packs. Anyhow, surely these motors have more than 150 peak HP?? And I too would like to know the answer to anshu's question.

Need more passing power from 1mz-fe.
