ES300 pistons on camry

[old red]

hi everyone
i know that the lexus ES300 and the v6 camry basically have the same 1MZ engine, but the ES produces more power (210hp VS 194hp) i'm talking about the '00 models
i read that the ES's cmpression ratio is 10.5 which is more than the camry's 9.1
so, is it possible to switch the camry's pistons and use the ES's insted? also, would that jump up the camry to 210hp?
keep in mind that the ES uses the VVT-i at that year model, but i don't know if the camry also have that.

thanks

they are both 10.5:1 its the vvti cams that make the difference I believe and a different tune. and higher compression makes more power. you can buy 12.5 compression and make a lot more power. I don't think anyone ever done that to a 1mz. something I'd like to see.

you seem to know alot
how can i get more NA power? i couldn't find any high compression pistons for the 1MZ or underdrive pulleys or anything
i already have headers, SRI, and a catless exhaust system
but as far as i can tell, that about it, there's nothing more

i'd only consider going into forced induction if i find a new TRD or Kazuma supercharger kit, wich is nowhere to be found

dude, i'm starting to think i should get another car!

well if you want the easy what every else has then you'll need another car for sure. Here is a someone you can contact to make some pistons for the 1mz.

you just contact them about what you want. then choose your bore size and compression. get 12.1:1 comp. I bet you'll get at least 34whp out of that or I'll make a turbo kit for you (not free). they should work. they'll charge you 487bucks if I can remember correctly.

hey old red, take samuri's offer for the turbo kit

running 12:1 compression would need an octane boost and not to mention more money for the tune and tuning device. without that you can't just slap on some pistons and expect 34whp

No you won't need to run anything less than 92 octane with a 12.5:1 comp.. I know crazy guys who run run 94octane on 13:1 comp. and have no knock problems.... not on a 1mz though. I've thought about a N/A build before I turbo'd my car. did lots of research and not too many people will go high compression. But the PIIISSSHHHHAAWWW sound won me over.
You will however need an safc( most likely greddy ultimate or blue would help with ingition control; anything to keep it from auto-igniting would be a lot safer) and a wideband to tune. all in all less than a thousand dollars to do that. so go on e-bay and buy my greddy BLUE before I have to let go only $112 dollars with free shipping!!! man I gotta stop drinking late at night.
I end up auctioning all my stuff off.

Just keep the engine stock and fab up a turbo kit. There seems to be more and more people doing the turbo V6 thing on the Camry's. There is a reason nobody has really done an all-motor V6 Camry, because the power gains are not worth the poor gas mileage and decreased driveability.

Turbo V6 on the other hand will be just like a normal 20 mpg V6 when out of boost. When you crave that added power, just spool the turbo and you're off. If I had the money, I would do a home made turbo kit and run a modest 6-8 pounds of boost on GT30R or something similar. This would be plenty of power and I would be able to keep my engine pretty stock without modifications to the tranny or internals.

dude i'm running on 95 octane all the time...
i didn't expect the "tuning" part though

is it a must?
keep in mind that i drive my car like i stole it

Yeah theres going to be tuning. you can do it with safc though...its five wires and some type of wide band. not hard to do. you'll need it becuase due to the changes in hp in every build you'll have to feed it fuel to keep it from running too lean. running lean is where you'll damage stuff internally; I dont care if its forged,ceramic blue print, or million dollar engine.
The fuel controller, lets say safc or something better will control your fuel by tricking your ecu into thinking its getting more or less air than it needs inducing its need to reduce or add. Then all the wideband will do is let you know where your at in air fuel ratio as you go from low throttle to high throttle. Lows your going to want 14.6afr (stioch) and for highs( wide open throttle) your going to want 12-13.5 for n/a motor.
If you go Turbo 1mz then you'll be one of very few less than six people in the world I believe. and if its another gen4 then we're going to have a problem. as I thought I was the only gen 4 turbo1mz in the world seems somebody found possibly another....I'm just gonna pretend that other is a gen4.5 like I thought, and custom did his gen 4.5 trunk with carbon fiber . OH yeah!!!

thanks for the info but i already know that, the problem is that where i'm living we don't have adequate experiance in installation... i used to have a 2003 camry 2AZ turbo charged, we burnt the ecu trying to wire the safc neo, that's why i sold it and that's why i don't wanna get into turbo-charging, aside from the continuous exhaust and manifold leaks and aside the oil leaks and...etc
i've had enough

by the way, i thought i was the only one with a turbo 2AZ, turns out there are two other guys in my country (saudi)
and there are a couple of turbo-charged 4th gen v6 camrys here
onle of them did 482whp on a dynojet... hhheheh

thanks for the info

i'll do more searching on the ES300 cylinder heads... see if i can directly swap them without having to tune anything or swap the ecu

if your not willing to trust a used SC kit(which are fine to use) or custom turbo then yeah, youve got the wrong car. ull spend much more squeezing NA power out of her then a turbo or SC would cost.

I know more about turboing the 5sfe then I do the 1mzfe. From what I've noticed around here on tn and on cardomain, more and more people are turboing their camry's. Although there are more turbo 5sfe's than 1mzfe's it seems. But if you want to turbo the 1mzfe, you should read all the turbo threads, especially the ones where tony the tiger offers his knowledge. By the way if you sold your camry what car would you realistically be looking to get?

Ohh you already know all that? then WTF did you ask if you have to tune? you wanna do high compression N/A build but don't want to hook up five wires off an safc to your ecu. becuase you'll screw up? good luck.
BTW hks boost's car is a gen 4.5 as all the others you mention.

im doing internals in the next couple of weeks (blew my motor). I want to keep same compression, but want better freakin internals. ANYONE know of ANY internals (non oem) that are a step up from toyota oem rods and pistons?

Hi; I need advise. My 97 ES300 burns 1 quart of oil every 500 miles. Due to leaky valve guide seals it sends out a huge ball of smoke after sitting for a few hours on starting. My mechanic told me that the car can run for a long time if I keep it full of oil. I suspect the oil rings are bad on some of the pistons as the plugs get ugly globs of deposits. What should I do to this engine if I open it up to repair valve guide seals and the piston oil rings. The car is in excellent condition except the last owner didn't do routine maintenance. It has 70Kmiles on it. Is this engine worth repairing? Mike
