The v6 has the potential to be a good turbo charged engine. There are some good aftermarket pistons that you can drop in to lower the compression ratio to a good number. The problem is finding someone who's willing to make a kit for a group who doesn't even want to pay $300 for quality headlights =/.

Just out of curiosity, how much boost can the 4 cyl handle safely? I can't seeing it getting into the 300 range w/o building up the engine.

I'm not sure about the i4 that comes with Solara's. I know that 3s-gte's run about 400whp stock without needing to be upgraded. My current block is stock (I've gone through a few...) 3s-gte and it's got 348 to the wheels. I guess there's not way to tell what the internals will handle until someone hits the limit though.

Our 2AZ-FE engines are built very well!Image

Tech Briefs
Toyota's new inline four-cylinder engine


The 2AZ-FE VVT-i powers the Japanese Estima minivan and will be Toyota's "core" engine for various mid-size cars, including the company's second-generation gasoline/electric hybrid and the forthcoming Camry replacement.

The 2AZ-FE incorporates Toyota's latest engine technology, including dual overhead camshafts that are driven by a single stage roller chain of 8.0-mm (0.3-in) pitch, enabling a narrow included valve angle and compact combustion chamber shape.

Toyota is accelerating hard on its "core" engine update. Significantly, these engines share the second character "Z," beginning with the type-ZZ that was first adopted in the U.S. Corolla and more recently in the revived mid-engine sports car MR-S. It was followed by the NZ-family propelling various small vehicles, including the Echo sedan.

The Z-gen engine for Toyota's mid-size cars and vehicles is the all-new type-2AZ-FE, making its first appearance in the second-generation Estima minivan (the first-generation Estima was the Previa). The 2.4-L 2AZ will power the next-generation Camry replacement as the base engine and other future mid-size vehicles. 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 type 2AZ-FE engine that powers the Estima minivan 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.

Why is it I always get stuck with a car with no aftermarket support.... First my maxima. The version I had didnt give no support.. Now the solara V6..... Gay...

You missed one important thing. "Open Deck". That makes it less stable than a closed deck under a turbo application. Not saying you can't turbo it, but don't overdo it!

DatSRBoi - Hopefully me and Josh can get to work on some things for the car. It's not the car that's bad, it's the compression ratio that makes it difficult to mod well without changing things like pistons :(.

Yeah.. Be cool if you can built a low boost kit or something... becuase getting motor rebuilt for higher boost is really out of the insanity on price..
