I guess that when people do a search for FE3 they come up with alot of useless threads telling people to search and when they do ask they get a lot of harsh answers. (sorry to all that have recieve harsh answers from me)
So to make it a little easier to find FE3 info I have made this thread. Feel free to add on to anything I don't cover.

First question:
What is FE3?
Fe3 is a 2.0l 16v DOHC engine that is found in euro and japanese spec mx6, 626, and capplea cars.
1998cc 121.9 cu in. 2.0 liters
86 mm bore 3.39 cu in
86 mm stroke 3.39 cu in
Aluminum head, cast iron block
Dual overhead camshafts, 16 valves
Here is a pic from FE3Ts site.

(from JayB's website)

Will it fit my car?
As long as you have a 88-92 MX6,626, or Probe.

Is it a direct fit?
Yes, everything bolts right up.

Can I use the DX/lx tranny with FE3?
Yes, just be carefull with your shifting and if your planning on adding boost you may want to go to the GT tranny

Can I use the F2T or F2 ecu with FE3?
Yes, you can as long as you extend the dissy. You can use the F2 or F2T ecu but it will not running the FE3 as it is intended.
A better option would be to use a standalone ecu or FE3 ecu.

Can I use the BP ecu from a protege?
Yes you can as long as you have all the wiring and proper conections.

Whats is VICS?

The intake are also a jewel.
its a variable intake with 2 sets of runners.
1 long set for low rpm torque and 1 short set for high rpm power

Also you can control the vics operation with a stand alone ecu or an rpm activated switch.

What parts do I use for FE3?
You can use 98 KIA sportage parts, like the water pump, timing belt, head gasket, pistons, etc...
Use F2 oil filter, miata spark plugs or just go to the parts store with the ones that came in the car. As miata sparkplug wires.

What is the performance of the FE3?
The FE3 is just a little faster than the F2T. It revs higher in the rev range but doesn't produce as much tq as F2T. You can expect low 15s runs from a well tuned FE3 and posably 14s if you a good driver.
Also It has been noted that FE3 has a top speed of just over 280kmh or 150mph.

Was there ever a turbo FE3?
Yes, it was used in a rally car in the early 1990s. Only 28 were made. They the engine code is FE3T. They are not avaiable.

Can I turbo FE3?
Yes. Turbo FE3s produce huge amounts for hp. They are capable of over 500hp with a turbo. JayB had his FE3-T runnig 11s 1/4mile times.

Where do I get FE3?
Check with your local Japanese Engine Imports. Or check to see if JAyB has any. Also there are avaible in Colorado at a place called All Japanese Engines
Ph: 303-234-9528
They should be able to souce one. But make sure its complete.

If under 12 psi nothing really. The rods are fine and the cat model pistons (either 9.4 Mazda or 9.2 Kia) are fine.
I tend to disagree with this a little. (from experience) I am running 15psi on a regular basis and am having no problems, well besides traction problems. Yes this is on ALL stock parts in the FE3

The stock ones that came in the cat model

hmm interresting, yesterday when talking to Jay B. i found out there are also different cams like i have the FE5A also another member told me that.
well the head u see in the pic is from a GT with no cat no O2-sender. except the same as i sent u the wiring from. i dont know what that number stands for.

So does the cam lobes ride directly on the lifters shown in the picture, and they in turn sit directly on the valve stems?

The KIA is an FE3. Its just made for RWD.KIA cloned the FE3 thats why we you kia parts for it.
More accurately, Kia manufactuers it under license from Mazda. They purchased tooling and copies of blue prints. It is the same engine other than some minor changes.

The most significant change, as related to a swap, is that Kia decided to use the crankshaft from the RF 2.0 diesel (with the 8 bolt flywheel) to save manufacturing and inventory costs as the crank is common to both engines. The Sportage is sold mostly with the diesel engine in other countries.

well, how you can see that is a real FE3 ?
i mean , theres some numbers and letters printed on the head or the block.
please just tell me where i have to look and what ''numbers and letters'' i have to find to be sure that this engine is FE3 insted of open it and see the internals for real judgment.
i want to get the one with the lower compression.

When you are looking at the motor as if it were in the car, on the head right below the valve cover, on the left hand side is stamped FE3N. That is how you know

Hey guys is there anyway to differentiate between the 9:1 and 10:1 versions other then the cat? Cause if the motor is out of the car and already here how would you know?

Pistons. Look down the sparkplug hole and if the pistons are slightly domed with a round dome then they are 10:1. If the pistons are slightly dished they are the lower CR items.
