The S in the 2JZ-FSE represents direct injection.
Injectors squirt fuel directly into the combustion chamber. I'm led to believe they also run low lift cams (6mm rather than 8.3mm) and have shimless buckets (like the 1SZ-FE).
I doubt you could get one here cheaply as they are a pretty recent introduction in Japan.

1999 onwards
hmm, wouldnt direct injection result in a poor AF mixture versus mixing pre combustion chamber(intake manifold)?
Benefits of this engine configuration would be?

Lifted from this website:
http://www.sae.org/automag/globalview_01-00/02.htm
"A significant addition to the JZ family of engines is the 2JZ-FSE, a DOHC 24-valve 3.0-L unit, which is Toyota's second D4 direct-injection gasoline engine. As its designation indicates, it shares its lower half with the 2997-cm3 2JZ-GE unit with 86.0-mm (3.39-in) bore and stroke. The D4 upper half is unique to this engine, and represents the state of Toyota's direct-injection art. The 2JZ-FSE's power and torque outputs are the same as the port-injection 2JZ-GE's at 162 kW (220 hp) and 294 N•m (217 lb•ft), but at lower engine speeds of 5600 rpm and 3600 rpm, respectively. The engine's compression ratio is a higher 11.3:1 vs. the port injection unit's 10.5:1, with both engines using regular-grade unleaded gasoline."
"The new 2JZ-FSE's stratified charge combustion envelope has been extended to a higher vehicle speed range of about 120 km/h, adequately covering Japan's real-life highway cruising. Fuel economy, quoted at 11.4 km/L (27 mpg) on Japan's urban 10/15 mode for the Royal, is about 21% superior to the previous port-injection model. At high-load conditions such as rapid acceleration and high-speed running, the engine operates in the stoichiometric zone with fuel injected during the intake stroke. One of the two straight intake ports is fitted with a flow-control valve, its opening and closing improving cylinder filling and combustion efficiency. During low-speed, high-load operation, this valve is fully closed, with the air admitted through the single open port, accelerating flow speed and improving cylinder filling. The flow-control valve is fully opened during high-speed, high-load operation, introducing ample air. A transient "weak stratified charge" zone, with an air/fuel ratio of 18:1 through 25:1, ensures a smooth transition between ultra-lean stratified-charge operation and homogeneous-charge combustion. Fuel is "split-injected" partially during the intake stroke and the remainder during the compression stroke."
"A single stage cogged belt drives the exhaust camshaft. The exhaust camshaft carries a vane-type VVT-i continuously variable intake valve timing device and drives the intake camshaft via a split and spring-loaded "scissors" geartrain. The VVT-i has a variable timing range of 40°. The camshaft acts on valves via shimless bucket tappets. The intake and exhaust valves are inclined at a narrow included angle of 22.6°, vs. the port-injected 2JZ-GE's 45°. Valve diameters are 33.5 mm (1.32 in) for intake and 28.0 mm (1.10 in) for exhaust vs. the 2JZ-GE's 33.5 mm (1.32 in) and 29 mm (1.14 in), respectively. Lifts are 6.0 mm (0.24 in) for either engine type. The induction system employs a variable-length ACIS (acoustic control induction system) to exploit the incoming air's pulsation to obtain inertia charge effect."
Hope this helps a bit Glen.

Sounds like a hell of a lot of technology
How many years till this hits here?
Swap over the GZE exhaust valves into the FSE ?

A few years yet.....these are all JDM motors. I got a 1998 VVTi 2JZGE mid last year for not much, but I haven't seen a 2JZFSE anywhere.
I don't think putting the 29mm exhaust valves would help much. The exhaust ports are the limiting factor, not the valves. If you wanteed to get really serious, Manley or Ferrea have 30mm exhaust valves and 34.5 mm intake valves, but you'd have to get very serious with porting and cams.

Dave, your a wealth of knowledge on the topic
How much can i expect to extract from the 2jzge with basic mods
extractors, exhaust, ported head, decent intake
180kw flywheel?
200kw a possibility? im guessing heeeeeaps of $$$
am i better off with a 7mgte then?
ta, glen.

hehe carbs
what are the bellmouths worth?
And this sort of setup is only good for racing isnt it? Heaps of top end and not much driveability?
This is a road car, would the same setup work, ive got a funny feeling not really.
And are you running bigger injectors?
ta, glen.

That's an all out race car Glen. It wouldn't be streetable.
For a streeter, I'd suggest doing the stuff I suggested first up. This will result in a handsome increase in power.
Remember, these donks in 1500kg MkIVs are pulling 15-15.3 sec quarters. Take 200kg out of the equation in your Mk2 and suddenly you'll have a fairly interesting equation.

Err Glenn,
From personal experience, put the motor (stock) in the MKII and see how you like it. I found it to be very impressive on the 200KG+ heavier MKIV, so I can only drool at what it would be like on the MKII!  When I say impressive, it was really impressive on the race track... so yeah.... *homer drool*
Cheers

Absolutely. When Nishad's MkIV hits the road, get him to take you for a (mild) fang.
Then consider that every 100 kg you lose is (roughly) the equivalent of gaining 30 hp, the 2JZGE powered Mk2 (approx 200 kg lighter) is looking like a reasonably good combo.
Of course, if you have your heart set on a turbo, forget it.

My heart may be set on a turbo
But my head is set on my bank balance!
the 6M was fun for a while, now im just wanting more
