2AZ-FE Turbo Setup
 

So far I've got the following stuff.

Turbo Manifold
Precision T3/T4 Turbo
630cc Injectors
Turbo Concepts Wastegate
HKS SSQV BOV
Unichip w/PnP Harness with Turbo tune
Intercooler (need to sell, I want a smaller intercooler)

I guess all i need know is a downpipe and intercooler piping with all flanges and i'm ready to rock!

And?

Re: 2AZ-FE Turbo Setup
 

And nothing... since I haven't seen any discussion about a Toyota 2az-fe motor i decided to start this thread.

Re: 2AZ-FE Turbo Setup
 

...and lest us discuss the motor, as this is the general discussion forum. I personally know nothing about the motor so I would in fact be delighted if someone would educate me on the positive aspects, general pros-and-cons, and overall cost effectiveness of this setup.

Re: 2AZ-FE Turbo Setup
 

The 2AZ-FE incorporates many features of Toyota's dual-overhead-camshaft,
four-valves-per-cylinder engines, including the slant-squish combustion chamber,
offset cylinder and crank centers, and the VVT-i continuously variable intake valve timing system. The aluminum engine measures 626-mm (25-in) long, 608-mm (24-in) wide, and 681-mm (27-in) tall.

The 2AZ-FE obtains a total displacement of 2362 cm3 with 88.5-mm (3.5-in) bore
and 96.0-mm (3.8-in) stroke. The cylinder block is now an open-deck, midi-skirt die-cast aluminum type with cast-in iron liners and a die-cast aluminum lower crankcase and a stamped oil pan. The forged steel crankshaft is fully balanced with eight counterweights and supported by five main bearings. A helical gear pressed in No. 3 counterweight drives twin contra-rotating balance shafts
in the shaft housing within the lower crankcase. The balance shaft geartrain includes plastic Nos. 1 and 3 drive gears, meshing with steel gears.

The dual overhead camshafts are driven by a single-stage roller chain of 8.0-mm (0.3-in) pitch, enabling a narrow included valve angle of 27.5°. The camshafts act on four valves per cylinder via bucket tappets. As in the recent Toyota engine practice, no clearance adjusting shim is employed. Valve diameters are 34.0 mm (1.3 in) for intake and 29.5 mm (1.2 in) for exhaust, with 8.0-mm (0.3-in) lift for both intake and exhaust. The four-vane VVT-i device is fitted on the intake camshaft, altering timing by 50°.

Fuel is injected sequentially via an ultra-fine-atomization injector with twelve small injection holes, each 0.18 mm (0.01 in) in diameter. As in the smaller NZ engine, the new AZ adopts a plastic, built-up, and vibration-welded intake manifold integrating a large volume plenum chamber (3.5-L (214 in3) volume including a 1.3-L (79 in3) resonator).

Twin three-way catalytic converters, each with a 0.84-L (51 in3) volume,
are mounted immediately downstream of the stainless tubular exhaust manifold.
The front exhaust pipe, collecting from the catalysts, has a separator in the pipe that reduces exhaust gas interference and improves low- and mid-speed torque.

The 2AZ-FE engine is rated at 118 kW (160 hp) at 5600 rpm and 221 N•m (163 lb•ft) at 4000 rpm on a 9.6:1 compression ratio, requiring regular-grade, unleaded gasoline.
A smaller version of this engine, the type-1AZ 2.0-L unit, powers the recently updated RAV4 light SUV. The Japanese version of this engine, designated 1AZ-FSE, features the fuel-efficient "D4" direct-injection head.

Unichip is ------- shitty.
You'll never find a unichip dealer that cares anything about isntalling, or tuning that engine. Or any Toyota in North America for that matter. I know I've ripped out two Unichip installs on the Lexus v8's. Any they're ------- stupid. No end-user tuning. They cost what full blown mother ------- management does.
Get an SMT...
630cc injectors are mother ------- retardid. Whoever told you to get 630's is an idiot. Well over 450 horsepower worth of fuel. You're just making trouble for yourself having to re-tune them.



2az-fe is a great mass production big car i4. Big torque curve for an N/A i4, good economy. The problem you are going to run into is very high compression (10.8:1), high ringland location, light weight Toyota pistons. You'll crack those mother ------- ringlands off, or blow a hole through a piston the second you let any form of pre-ignition take place in that engine.
DO NOT let some mother ------- moron at a shop tune that thing to 12.5:1 & call it done... You need to run that bitch deep into the 11's IMMEDIATELY at the onset of boost for long-term survivieability.
Run water injection... It'll save your ass.

The enigne itself is plenty strong. The only weakpoints are Toyota's real OBD-II Air-Fuel sensors, and the pistons. They're not weak as glass. Don't get me wrong they will take some raw power output. But they will not handle any amount of pre-ignition / detonation. I would stop long before you hit 300hp if you're not tuning quite rich & running water injection...

Re: 2AZ-FE Turbo Setup
 

new pistons + boost = revamped toyota reliability

Re: 2AZ-FE Turbo Setup
 

ive heard the 630cc injectors are to big... but there were taken directly from the Turbonetics kit for the Scion tC... also the Unichip also has been taken from that kit also. So over all... the unichip will be tuned to used the 630cc injectors.

FYI: I am very new to turbos and cars in general

Re: 2AZ-FE Turbo Setup
 

Did you read a damn thing Toysrme said? Unichip has no user-end tuning. Get some smaller injectors and an SMT and be done with it.

Re: 2AZ-FE Turbo Setup
 

Blah blah blah...words and no pics. Me no like to read..pictures..colors..me happy. :1

Re: 2AZ-FE Turbo Setup
 

didn`t a bunch of camry and Tc guys has been boosting their ---- pass 350whp???

Re: 2AZ-FE Turbo Setup
 

se :8

Re: 2AZ-FE Turbo Setup
 

Yes, but not reliably, and not at those power levels full time.

rockbrawler884 I have alot of experiance when I tell you.
Unichip is by faggots, for faggots.

And 630cc injectors are too god damned big. If this were any other forum but HMT I'd do the math for you, but since this is HMT I'll tell you to do some mother ------- research & then do the math.


The farther off the injectors are from stock, the more, and more often you have to retune. Theworse the engine tune under load is, AND THE FASTER & WORSE THE LONG TERM FUEL TRIM WILL ---- YOU UP UNDER BOOST.





I don't give a flying ---- what turbonetics sells in a kit. Turbonetics doesn't sell tuned cars. They sell random in a box. No different than SSA Autochrome, just with hardware not quite the same level of asstasticness.

Re: 2AZ-FE Turbo Setup
 

Oh that's why this motor sounds familiar its the camry motor.

Re: 2AZ-FE Turbo Setup
 

They use it in alot of things.
but yes, Camry Highlander Previa Blade tC

Re: 2AZ-FE Turbo Setup
 

hmm all I hear is bad things about shops tuning the new tC. My friend has one and it's not particularly outstanding out of the box. You're saying that the slant squish design of that head puts extra strain on the lands, with weak ass pistons to boot? Because I'll be sure to make my friend read this thread if so. He wants to go turbo with his.

Re: 2AZ-FE Turbo Setup
 

No, the more modern high compression Toyota pistons moved the ringland location up the side of the piston, and the parts have been lightened. It's a tuning issue. If shops wouldn't tune them half-assed, there would never be a problem.

Still forged steel rods, and the piston construction itself is nice. :)

Re: 2AZ-FE Turbo Setup
 

So for what you have so far, how much have you payed because i have a 07 tc also and am trying to see what i can expect to pay for parts

Re: 2AZ-FE Turbo Setup
 

what car is this build for? (isnt the 2az-fe the new tc engine, also they come in camry's) if so i got an '07 s/c'd and because of the high ass comp. (and probly a shitty tune) my car runs pig rich....my a/f sometimes hits 10.8:1

2002 Toyota Solara SE 2.4L Turbocharged
I just Simply Raised the Fuel Pressure With the Stock 12 ports per Injectiors. By Raising the fuel pressure more Fuel is Injected for the Same Milliseconds that the Injector is Open
EFI works on a given fuel pressure open for a certain time based upon all sensor input. By Raising the Fuel Pressure I have been able to Fine Tune my engine with a T4 Turbo. Raising the fuel pressure put more fuel Through the injector.
At 9lbs.of boost It produces 365 HP.
You do not want high compression pistons when super or turbocharging.
Mine are 7.5/1 as I am already Pumping additional air via Turbo. High Compression Pistons should be a choice if you do not want to Turbo or Supercharge your engine to get More HP output.
