Modifying Camry Engine 1MZ-FE

[Camry_Grande]

Thanks all. I'll look at the minor mods and stay within factory guarantee + legal limits. In the long run, will trade in for an Aurion (once I read the reviews about them, of course).

[thechuckster]

i think Oz Toyota are looking at using Super chargers in the new or next-gen sporty model Camry/Aurions... if you can wait that long.

The only way to legally SC a 2006 model would be to use a factory kit.

You could build up another (non-ADR-compliant) 1MZ engine, remove the current engine for safe keeping, do good skids with newer engine, then transplant the original engine before trading up to the Aurion ... but that's probably outside your budget unless you work in the trade.

cheers,
charles.

oooh 6 bolt mains
oooh beef rods
oooh forged pistons

Looks very much like a 1uzfe missing 2 pots

i was under the impression that even simple things like a pod filter ie any non geniuine/factory part voids warrenty

With that budget you can have twice what you've asked for...don't go too spastic with the launches etc and the box should hold up ok (ish) too. You're gonna need the clutch sorted though.

Single turbo off the stock manifolds is probably the easiest. A decent ECU wired up as a piggy back so it just runs injectors/timing and get a feed off a few temp sensors. Keep the stock ECU there to run all the boring bits. Bigger injectors and pump upgrade needed but most of the stock hardware should be OK (ignition etc).

I'd run a WI setup for a bit of added safety and a decent FMIC (could be a challenge?)..alternatively an a/w setup might make life easier for you.

Anyways you have the main thing well and truely covered...bucks. Of course if you take to the usual big name workshops they'll mow thru it pretty quick...best off doing the rounds based on advice from the guys here and work out a deal with a non rip-off merchant.

Your target is so realistic it's refreshing (so used to hearing clowns want it all and pay nothing).

well your the only person that said my TRD stickas wouldnt add 645.5 hp at least...

maybe CAI + higher flowing filter, and a decent exhaust (maybe headers) to start with...

although all that will be useless if you decide to go turbo.

SC is probably best bet.

you can also find Tony on www.toyotanation.com under the username TonyTheTiger. it's probably best that you search through his posts and read some of the build up threads that he has made, as they will depict in a fairly good manner, what he has achieved.

a basic run down on what he did was get some headers from JP Performance IIRC and then made a pipe from after the merging of the two banks, brought it up to above the gearbox and then all the associated piping required once the turbo is in place.

His current build is probably a lot more than what you are after, however his inital setup had just a CT26, the second stage was the same turbo but with a 57 trim compressor wheel and that had plenty of power. it'd be great too see you do this to the camry as that would almost be a first i'd say. also check out some of the solara forums as there is one person who went turbo 1mzfe as well. his setup is very similar to Tony's and you'll most likely end up with that same layout.

Supercharger kits arent available off the toyota shelf from what i can remember, the one that was available over there was designed for the 1mz-fe and would only fit on LHD camrys, and solaras. there was another company URD that actually made a supercharger kit for the RHD version of the camrys with the 1mz-fe and there was a guy in melbourne who had his gen4 camry with one installed and working soundly.

its been awhile since i've been keeping up with the camry modification scene on regular basis, so my memory is moreso a reflection of past mods i've seen etc.

btw, can i ask is your camry the manual or auto version?

Cheers

Edit: whoops, thanks for the JSC, had the wrong one in my head

Hey dude ... i thought the TRD supercharger available in the states was for the 1MZ-FE?

It's a four speed automatic.

No no no no no no no no no. If you don't have any experiance playing with any of the v6's...





Headers area huge waste of money. Long tube headers, when designed well, can do a good powerband increase across most of the board, and give a good peak gains. The problem is that they're extremely difficult to route, and ungodly expencive.
Short tube headers on any v6 are the biggest F'ing power adding joke of all time. Worse than the $15 ebay resistors. They provide no more power gain than a typical good y-pipe, at 3-4x the cost.

The only modification that has any price / performance, and performance gains worth mentioning on an N/A engine is a custom Y-pipe with no, or a high-flow cat. Not quite worth what they are on most nissan engines, but they're still a good, solid 15-20bhp peak gains, with increasingly larger gains past peak power.
The intakes make almost no power, it is common to LOOSE power across the majority of the powerband, and any power gained will be at horsepower peak & above. - Useless! Intakes are for sound, and looks. Performance is a trade-off that averages out to little, to no gain overall.
Cat-back exhausts qualify as intake mods. The stock exhaust is simply not restrictive. Any power gained by upgrading one will come at horsepower peak, or higher.
Generally. You can get about 10bhp PEAK power with fuel, and ignition tuning.
An intake manifold will give good peak power gains from peak horsepower & above.
Toyota stock cams are crap across the board. You can get them reground to better profiles with more lift. The later 1mz cams are not as bad as the vast majority of Toyota's cams are. (Still the same pissy .310 & .300 lift, but atleast they get 244* & 236* of duration). Most of the time, there is no penalty at 2750-3000rpm on the v6's goin from stock cames, to more aggressive 268-272* grinds. Obviously... The cam grinder, his agrgessiveness & his profile pattern determines your gains.

n2o is great, expect to put in a new fuel pump. Highly recommended is the Walbro 190's found on ebay. Skip the 225lph+ units until you actually have more than 400bhp (298kw).
Turbo's are great... Much safer than the crap M45 based TRD Supercharger.

Tony's original 10psi CT26a (off a 7m-gte, horrible turbo mind you!), stock exhaust, stock engine, at this point it still needed more of a tune.


The 1mz's problem is not paper thin parts...... The rods are plenty big enough to out power what an unbuilt 3s-gte can make. The problem with the 1mz's come with the location of the piston rings. They too high on the piston & are common to crack them off during any form on lean runing, pre-ignition, or detonation. Which they are somewhat sensative to for some reason. Blame the 10.5:1 compressio ratio, blame whatever you want. Who knows.

That problem... Is one that a very good tune job can take care of, along with water injection, and the correct setup. Keep in mind... The 1mz-fe's that *have* blown up, were killed by:
1) The G D TRD supercharger, which is too small for a Miata, let alone an engine 50% larger with atleast the same volumetric effeciancy. It is too small, the flow is too hot, and the fueling is not up to par.
2) Poor tuning.


350bhp has thus far proven a good power output range of the 1mz-fe. More is perfectly fine with n2o, or a turbo, but the tuning MUST be done. To put that into terms the rest of you can understand... It's basically a 3s-gte+ capible stock power output, with a 50% larger powerband size.
This is why 3s-gte MR2 to 6 swaps have become popular. The much larger powerbands all the v6's have access too also allows them to run circles around the BPU'd 3s-gte MR2's on tracks which thus far. The 3s-gte's produce much higher peak power numbers. That hasn't seemed to matter at all. Powerband > peak power if it's even near the same.
v6 > i4. LoL!




Camry_Grande, Buy a TIG, or MIG & learn to weld. Then spend $1500 on building yourself a turbo setup.
The fastest, cheapest ways to make your car faster would be:
1) High stall torque convertor
2) Valve body modification
3) n2o & mods to support it
4) Y-pipe
Forget N/A power. It isn't going to happen. If you just *feel* like throwing money at it N/A, you can make your 350-400bhp... With many thousands of dollars spent.
Past the n2o, a turbo is power king. Honestly... Put a y-pipe on it, then start saving money for a turbo. Maybe stop off for management, or a cat-back exhaust & intake along the way.

[Toysrme]

hmm... didn't know it was only 141 kw... the 2ZZ-GE makes about that much anwyay it's only a 1.8..

Oh give everyone a break with that useless comment. EVERY Toyota v6 of atleast 3.0: makes more torque at 1000rpm, than the 2ZZ-GE does PEAK. That includes the completely junky 3vz-e SOHC engine used in the post 22r-te, pre 3.4L 5vz-fe trucks.

The 2zz-ge is basically a factory race engine. The 1987 2.5L 2vz-fe makes the same basic torque, and couldn't be any less aggressive. (Mind you it's down 40bhp peak)



That little engine doesn't compair well to any of the v6's. Sorry. The best thing you can say about it, is that it's lighter than the oldest iron block v6's. Even at that... Not by enough weight to change a nyone's mind doing a v6/v8 swap.

coils ampliflier (like them AEMs and MSD things)... thinner HG..bigger injectors and throttle body...

It's COP igntion. What is he going to upgrade too that is going to put out more spark than he already has?
It comes factory at a 10.5:1 compression ratio. Why bump that any farther with a tiny head gasket? There's no reason to change the factory headgasket, it's MLS. So why crack the engine open for less than 10 horsepower & suffer possible driveability problems.
1mz-fe's do have a tendancy for pinging, detonation, and over-sensative knock sensors.
Why bigger injectors? They start at 240-250cc injectors. Good enough for 255bhp without a pressure bump.
Why would anyone upgrade from the two throttlebodies already installed? Toyota doesn't particularly undersize the throttlebodies on their v6+ sized engines. Even the older single TB v6's all recieved 70mm tb's. That's what 5.0L Ford's here upgrade too b/c they bolt on. LoL!



I'm not picking on you. I'm simply illistrating... Most things you *think* are going to give more power, are not. It's either going to lower power, or cost alot of money & do nothing.

Hey Toysrme

those are great factory looking graphs, where'd you get them?

[Vios-GT_07]

it's cool mate.. most people in the know have to have a go at others who are ignorant... it's acceptable behaviour (noobs beware!) i'd + rep you but.....

even though i never hinted at the 1MZ being inferior.. it has buggered me as well why the 1MZ and V6s have not much in terms of Peak HP but have insane torque levels (hence the avalon's ability to launch with massive wheel-spin).. they do rev high, from memory are capable of 7000 rpms.. i'd never mod a toyota's V6 as i believe they can be revved hard without much problems as long as they are cared for i.e. regular oil changes, maintenance.. IMO the V6s has that level of engineering it doesn't need to be mucked around with..

edit: if only i can get more info like this regarding the 1NZ ...

[oldcorollas]

just a note tho.. unlike the US, N2O is strictly prohibited on public roads in Australia. with the new regs coming in, you cannot even have it INSTALLED in the car (previously it had to be disconnected).. so N2O is not even an option.... plus he said he wanted LEGAL... unliek the US, you have to have things checked and approved, or yor insurance can be void....

[Toysrme]

Sucks for yall then about the n2o. Then personally. I would be all over a turbo on a stock motor.
Vios-GT_07 it's all cool. I aint killin ya. Just driving the point home than unlike alot of engines, most of the Toy v6's don't have much in the way-side of bolt on performance. (There isn't an aftermarket) but even if there was, most of the bolt-ons don't really help.

I don't really have much for most engines, but I do have the intro papers to the second year 1nz-fe & the prius's 1nz-fxe if you want them. Got aim?
