FE3 into P5

[iluvmacs]

One of the best things about the FE3 is the cylinder head. It flows like an SR20 head and can support much past 220 hp N/A easily. When you add all the bottom end stuff that it has, here comes the boost.

I wanted to swap in one of the heads because it flows so well, but with the bottom end and some valve train work this motor could probably spin past 7500k regularly.

Ok, Flyin' Miata used a 1.8-liter BP block out of a KIA because it has the beefier crank support (I think) that comes in the newer Miatas, for considerably cheaper.

They then built a 2.0-liter stroker kit around the 1.8-liter motor for their race car, (Track Dog, blue and white car) and their shop car (Elvis, blue car). They did not use an FE3. They built a stroker kit, which is now available for sale through them.

FM has never used an FE3 in their cars. Randy, who's site has been mentioned above, has been working on the swap into a Miata. It supposedly can fit under the stock hood just fine.

The FE3 is related to the F-series engines(F2T, FE, FET) and was originally called the FE DOHC, but some part numbers said FE3N, so the name stuck. It has a BP style cylinder head, but obviously because of it's larger size it flows more, and because of it's larger crank, rods etc, it can handle more power. If you put in aftermarket forged rods and pistons, who knows how much power that thing could handle. The good version is the 626 16v engine it originally came from in 1988-1992. They didn't sell them in North America, but if you can get one sourced from Japan, they make 170hp stock. The Kia version only makes 140hp, but from what I hear is just because it's lower compression and different ECU. Which means with stand-alone and HC pistons, that 170 is easily achieved.

This thing also has a crazy high rod ratio(150mm rods with only an 86mm stroke, ratio of 1.74). Not high for Indy V8 type engines, but very high for 4 cyl light weight engines. Which means this engine could absolutely scream, maybe 9-10,000RPM if you can get the cams and head to flow that well.

I was going to make an FE3 my next project car(between that an a 1.5 Protege...I have my reasons). Here's some good info...

Its a shame it can't 'truly' bolt-on into a BJ chassis...
