Hi-Port - Low Port Question

[CanadianG]

Whats the difference between the two and how do you know what you have?

[G-Forces]

Jeez I hope I get this right.

This is a low-port. Notice how the plenum (intake manifold) is situated?

This is a hi-port...

[CanadianG]

is a difference between the two other than visually?
Are they on different years? I have no clue since I thought all sr20de's were the same?

On the G20, 91-93.5 was the high port, the later models are all low ports from the factory. There are slight differences in the motor, but nothing major, the biggest difference is the intake manifold. The power bands are slightly different, not enough for most people to tell though. You can only notice the differences once you have quite a few mods and/or you get the car onto the dyno. The characteristics of the two motors are very similar, pretty much identical, expect when you look at them VERY VERY closely, then you can start to see very little differences.

Oh that's not my car above. At first I thought it was but I was wrong. I do have that stupid coolent resivoir next to my filter. That's one of the reasons the AEM intake didn't fit.

That's not coolant, that's brake fluid. Your coolant overflow should be located on the right side of the radiator (driver's side)

OOPS! that's weird... i was looking at the wrong thing. can that be relocated on teh other side of the battery, like in the front?
