Modifying Camry Engine 1MZ-FE

[Camry_Grande]

I am thinking about modifying my 2006 V6 Camry Grande to get more power. I am pretty new at this and am hoping for some much needed advice. How can I get the engine from its current 141kW output to say 180kW - 190kW? I am open to any and all modification options as long as it is legal.

Thanks to Vios_GT_07 for the initial advice. To add a few more details, I have around $10,000 - $15,000 to burn and am willing to go a long way, including super/turbo chargers. Which ones will fit and how much power they will add? I would like to go with the official TRD supercharger, but have read that it may have trouble fitting with an Australian Camry. In any case, where can you buy one and have it fitted in Sydney?

And oh yes, definitely want to improve low range torque!!!

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

i'd imagine it has heaps of potential though coz the camry engine is fully alloy hence being light-weight.. why not the common mods first and see how we go from there? how much are you willing to spend and what lengths are u willing to go to??

there's the basics e.g. extracors, piggy-back ECU.. CAI.. coils ampliflier (like them AEMs and MSD things).. which would see 150 to 155 kw..probably a port job, thinner HG.. (good luck finding one), bigger injectors and throttle body... on a bit of an aggressive tune short of getting bigger cams i'd say u'll get fairly close to your goal..

or you could do it methodically and work out what you need to do.

have a look at the stock torque numbers and how close they are to the engines capacity... then look at the power curve and see where the cams are working.

for that kind of increase you want to know that the exhaust is capable of it.. interms of extractor tuning and cat/muffler flow... Cat is mor eimportant as it is closest to engine and likely to be the biggest restriction in the exhaust.

cams will change where you make the torque, in the rpm range. this is where you will get most of your increase from.

the rest will just be making sure that the engine is happy at the increased rpm, ie intake, fuel etc. can it do it on stock ECU? maybe not.. do you want to sacrafice low and mid range to get that extra power? maybe?

what if you could keep your low and midrange, but increase the midrange and topend? turbo?

1mzfe has a pretty boring bottom end doesn't do much to about 4000rpm.

boring perhaps, but it still has one hmmm
peak torque is 4400 and peka power is 5800?

to get an extra 30% power... thats what? say 5-10% from breathing mods, and then 20% from rpm?


low boost supercharger better everywhere (except fuel)

[Norbie]

If you're looking to increase peak power output by 30-40% and improve low-rpm torque, it's not going to happen if the engine stays NA unless you can figure out a way to bore/stroke the engine by a significant amount.

Supercharging will acheive the result you're looking for, but how much are you willing to spend? There are kits available but they sure ain't cheap.

oh.. thats a problem...
ECU or cam changes etc will make it not legal from emissions point of view. if the SC has not been pre-approved for Aus, it will also not be legal...

being such a new motor, it has more strict emissions standards, so major mods are not going to be easy to certify (warranty?)

you could also reduce car weight.. effectively increasing engine power

be careful of the weaknezz of the 1MZ rods/pistons!! They are nice and light and thin.

I found a website once of some dude in the states going crazy with turbocharging his MZ engine in a camry.... he was getting decent numbers.


Personally i think there are significant gains to be had with some good headers and exhaust system combined with aftermarket engine management - just the same as there is with a 1UZ.

are you talking about Tony's camry? that thing is mad... has been discussed before

[Camry_Grande]

Hmm...on the weight front I don't think I helped it much with the additional stuff I have put in so far:

In order of additional weight:

- 18" wheels with low profile tyres
- amplifier and subwoofer
- sports note chrome tip exhaust
- iPod connector
- rear parking sensors
- window tint



Now for one more stupid question. If I do change the ECU/cams or add in an unapproved SC and hence break the emission limit, apart from voiding the guarantee, does this also make it not road worthy, i.e can the traffic authority keep me off the road?

Does anyone know the link to this site?

If your car doesn't comply with any of the ADR's listed on your compliance plate, your car is no longer legally allowed to drive on public roads. And yes quite a few of the ADR's related to emissions which can be voided by the above modifications.

Having said that, I'd wager a large proportion of the Toymods community drives around in cars which are technically no longer emissions compliant.

Shh, I've got no idea what you're talking about

[RONA]

Shh, I've got no idea what you're talking about

Pfft I doubt the cops would suspect a camry running nutty cams anyway

[lumpy]

Is there any particular reason you want to void the factory warranty?

FWIW I'd say the cheapest way to improve power would be to trade it in on an Aurion V6 when they are released.
