All the FE and F2 rods share the same 2.005" journal diamter, 1.055" big end width and 22mm wrist pin. The differences are in the length and duty.
The FE3 has a 150mm rod, the FE has a 152mm rod and the F2 has a 158.5mm rod. The FE3 rod has the most duty.
The cast iron 2.0 FE cranks are marked FE50. Sportage too.
The cast iron 2.2 cranks (all are cast iron) are marked F201.
The Forged 2.0 cranks I don't know as I sold my only one to JayB
The beefy FE3 rods are marked with FED on the cap.
Q: Does anyone have input on the actual numbers on the underside of the pistons, The FE3O or FEO3 (cant remember exactly) are the numbers that are Stamped on the underneath of my Factory Turbo "FE T" (2.0 Single cam) . Now what i am wondering is will these fit the Fe dohc and would i only have to swap, Crank and/or rods and/or pistons.
A: Although the SOHC 2.0 FE pistons will physically fit the bore (same 86 mm diameter and same 22mm wrist pin) they will not lower your compression the way you want.
The SOHC head is a closed chamber design and the DOHC head is an open chamber design. If you use very dished SOHC pistons with a head that has lots of chamber cc your CR will be around 6:1. That combined with the wrong valve reliefs makes using them not worthwhile or practical.
Comparison pictures are on my FE3 web page.
If you want to lower your compression of a FE3 then use the Sportage pistons or custom.

Knowing that the new Mazda 6 2.3 liter and the 2003 Ford Ranger are nearly identical engines (sans balance shafts and tuning parts) and that the Mazda 6 engine is loosly based on the FE3 dimensions (ala Chevy LT1 vs LS1), I ordered a 2003 Ranger head gasket to compare it to the FE3.
The bore spacing is identical and most of the oil and coolant passages are identical or very close. All but two of the headbolt are the same and the others are very close too. Three of the six oil drain holes don't match up at all so some blocking would be needed. The Ford gasket is thin two piece steel of .016" and supports a 89mm bore.
What does this mean? Mostly nothing other than if you wanted to get a custom gasket for the FE3 you could just reference the tooling from the 2003 Ranger and if someday the head or block of either promises more hp or reliability then they might be swapped without too much fabrication.

Problem four: Cam followers Cosworth engines use service-free hydraulic cam followers, and as the cam profiles are not very radical, and the standard engine is designed to rev to 6500 or thereabouts these are satisfactory. However when more extreme cam profiles and higher RPM bands are used, these tend to pump-up resulting in valve/piston contact. Every Cosworth engine I have seen has had 'kiss-marks' on the pistons due to over-revving. Valve piston contact is a definite no-no especially at the sort of RPM (8500+) I envisaged using.

i just pulled the head off my fe3 after 20000kms of full throttle driving bouncing on the rev limiting problem i was surprised that the engine was in excellant condition.
and also i found no valve kiss marks on the pistons as stated in the article above.

Q: Where did you get solid lifters? Are they from another car or custom????
A: The FE3 uses a 33mm bucket. I simply went down to a local head rebuilder and asked if they have any in 33mm size. They handed me 16 shim over bucket style with 30 shims for $40. The shims are 29.5mm in diameter. I don't know what engine they came from but suspect they came from a Mercedes or a old Susuki motorcycle as they had both had 29.5mm shims according to the searching I have done.
Q: what are those?? i need 5 HLA's and if i can use 5 of those CDI MB-ones (which i thought wouldnt fit) i might use them.
but i really shouldnt know how to fix the height problem.
A: If you simply need to raise the height of the lifter then you can use valve stem cap shims between the valve stem and the lifter base. I have used them for eons in order to use the thinnest over-bucket shim to lessen the weight of the valvetrain.
As dipicted and described on my street engine page about 2/3 the way down.
