I own a JDM swapped 3SGTE MR2 and an Impreza, I drive both very frequently and to be honest theres not much of a difference in terms of the butt dyno. Both are very torquey motors and the powerband hits nice and early. Compared to my old RSX-S, I really like the low to mid range power band that the turbo motors get instead of a higher revving NA motor. Thank god they didn't castrate this car like they did with the MR2 Gen 3. Either way the EJ20 is a VERY easy motor to get power out of and the only thing its really lacking right now is direct injection, which Toyota is going fix. Lets hope for version 7 EJ207 forged internals!!!! For you guys that don't know the EJ207 spec C(STI version 7 and 8) had a 8300RPM redline.

2/3rds...

but yes same bore and stroke. just minus 2 cylinders

I was going with cylinder numbers in case fractions confused too many people. Heh. But aside from the 86 X 86, and iron block they're probably quite different. I seem to recall that when they're mounted longitudinally (like in the Altezza), the intake and exhausts sides are opposite of the 2JZ. Either that or I was looking at a mirrored pic...

nope intake is on the left on both when look towards the crank pulley. you might have been looking at a sr20. dumb datsuns are backwards.

What do you mean by left/right (viewpoint or sides of the car?) and from looking at the crank pulley?

JZ cars, when standing in front, looking into the engine bay have intakes on the right side as seen from the viewers point of view, left side of the car.

I swear the 3S is opposite. I'm going to go have a look right now, just to make sure I haven't gone insane...

Edit:
Thankfully, not crazy...

IDK why, but I've loved Beams 3S head cover. :w00t:

Dixie - they're on the opposite sides. ;)

anyone know how long the rods are on the 2JZ?

I got 142mm off one site. But it didn't specify if that was overall length or center to center length.

Edit: That's center to center length.

Im an idiot. I guess after a good night of drinking and not getting any action, I make mistakes. (check the 3am post) Sorry everyone. :bonk::suicide:

It's ok. You'll never make that mistake with the boxer. Just remember the intake in on the top and the exhaust is on the bottom. :)

But I have met a moron that couldn't tell which side is up or down on short block EJ22 engine before... yes, he didn't know what he was doin' and disassemble his engine.

People can be pretty amazing sometimes. lol

Seriously! How he couldn't tell the difference?!?!?! There's an oil pan on the bottom! Anyways yes, some people amaze me sometimes.

2JZ has slightly longer rods than the 3S.

makes me with i had 182mm rods in my 3S... :(
