Engines: Toyota.

If we don't think a four cylinder is the right fit, then maybe we need something with 6 cylinders.

Toyota makes two engines that fit that bill. Lets start with the Non-turbo 2JZ-GE.

Here's the motor in it's natural home, the Lexus SC300. I'm starting here because we need to point out something. That giant pipe over the hood. We'll see that a couple of times this week.

So lets talk spec's.

• 220hp.
• Weighs about 450lbs.
• 3.0l displacement.
• Cross flow head with 4 valves per cylinder.

We would need to make some changes to the motor for our engine bay.

Aftermarket exhaust manifold and a new intake manifold setup would put us at about 250-275 horsepower. No turbo means INSTANT throttle response  Not quite 300 horsepower, but still very respectable  More importantly, it fit's the spirit of the car. Silky smooth power and enough grunt to force our lightweight chassis to fly.

Also, if we ever decide to add a turbo, this block and head can support 500-600hp without any internal modifications. A factory based turbo kit can be fashioned for under $1000.

So the other motor?

The Toyota 1JZ-GTE.

Let's break that name down.
"JZ" - Engine family. Same as the 2JZ so there's some interchangeable parts.
"G" - Performance tuned Cylinder head. (Rumored to be designed by Yamaha.)
"T" - Turbo. In this case, Twin Turbo.
"E" - Electronic Fuel Injection.

Specifications

• 280hp. Although with the custom intake and exhaust piping, more like 300hp.
• 475lbs fully dressed with turbo's and accessories.
• 2.5l

How's it look in a 260z?

There's some problems with either JZ motor.

Their usually "front sump" oil pans. That means there's a big hump in the oil pan under the front of the engine. They would need to be converted to rear sump systems.

Transmission. The 2JZ-GE can use a Toyota W58 transmission that easy to get, and the 1JZ can use a R154, again easy to get. However if we go 1JZ, that R154 needs a $400 bell housing to mate the transmission to the block.

Cooling. The 1JZ would have a very complicated turbo and exhaust system. Two turbos means twice the heat.

Cost. Their not cheap. Given the conversion work that needs to be done to adapt them to our Datsun, the 2JZ is going to be $1300-1700 and the 1JZ will be between $1800-2500 with transmissions.

The good news is if we went with the 1JZ-GTE we can install it and make it run in as close to stock as possible and have a monster of a car.

The 1JZ-GTE is very high on my list of possible choices.

Tomorrow, lets talk Nissan Inline 6 motors.
