Crankshaft:
All of the F2 blocks use the same crank therefore the same
balance and any parts that bolt to it will interchange between
vehicles. This crank includes the cars mentioned above.
Crankshafts from the FE and FE3 can be used as well with
modification of the internals. The cranks from the FE and FE3 have
different balances and strokes so you will need the entire
rotating assembly and new rods to adjust for the stroke. If using a F2 crank to stroke an FE or FE3 engine keep the harmonic ballancer from the F2 on the crank or have a machine shop ballance the rotational assembly. For those
who know of the Kia motor using the B2000 FE block the crank is
swappable but the flywheel and harmonic balancer from the
KIA MUST be used.
Flywheels:
Being since the cranks are the same all of the flywheels for
the F2 cranks are interchangable. I do not know if they differ any
between the cars and the trucks. The car flywheels weigh 29 lbs,
the truck is either the same weight or probably heavier. And of course being since all the flywheels interchange all aftermarket flywheels will interchange too, including lightweight flywheels such as the 9 lb flywheel from Fidanza.
Bolt patterns between the FE engine found in the B2000 and B2200 between 1986-1993 are the same and can be swapped if you use the clutch made for that particular flywheel. The B2000 flywheel is 2 lbs lighter than the B2200 flywheel, so to install the B2000 flywheel in your B2200 you must have not only the flywheel but also the pressure plate from the B2000. Swapping the B2000 flywheel onto the B2200 flywheel would probably net a 1.5-2 hp gain. If you wish to use the lightweight fidanza flywheel on your B2000 you need a pressure plate from a B2200 to go with it. You do not have to have the friction disk if you don't have one the disk itself will interchange regardless of the flywheel or pressure plate you use but it is advised to replace it and the pilot bearing while you have it appart.
The bolt pattern on the Kia Sportage engine is different making it not interchangable.
Crank pulleys:
Since it does bolt to the F2 crank the crank pulleys from the
cars above will also interchange. Because the belts on this pulley
are different you will need the alternator belt and pulley with
the lower alternator bracket. Please see 12v
Pulley The aluminum underdrive pulleys made for the cars will
interchange the same as the stock pulleys but it is highly
unadvised that you use them. The crank pulley is known as a
harmonic balancer it is called this because:
- 1) it is balanced for the crank.
- 2) It is designed with a certain weight to absorb vibrations
in the crank.
- 3) They have a layer of rubber sandwhitched between two
layers of the steel pulley that dampens tortional vibrations.
The big don't dos with crank pulleys are:
- 1) Never use a solid (no rubber dampener) pulley, it will
not dampen the vibration.
- 2) Do not use a lighter pulley than what is designed from
the factory if it is lighter it will not absorb the vibration in
the crank. Alluminum Underdrive pulleys violate both of these
and are known to reduce the life of the crank.
Although the harmonic balancers on the 86-93 B2200 and B2000 look the same they each have a different ballance, so don't interchange them unless you swap the crank with it.
Exhaust Manifolds:
The exhaust manifolds between the 88-93 B2200/2000 should
interchange. Also the exhaust manifold form the F2T engine (Turbo
F2) used in the turbo 88-92 626, MX6, Ford Probe. This makes an
easy option to turbo your truck if you don't want to have a custom
manifold made.
Cylinder Heads:
There is a fairly wide variety of interchangable cylinder heads
that fit the F2 all of the F2 cylinder heads are interchangable
but the B2200 is the only one that is 8 valve. All of the other F2
blocks in the cars use a 12 valve head. Although this head is
interchangable there are a couple conflicts.
- 1. The distributor comes out of the back of the cylinder
head and will interfere with the firewall when putting it in the
truck. To get around this you must either modify the firewall, use a distributorless ignition or find parts from a 12-valve JDM Truck engine.
- 2. The intake, the truck intake will not bolt up and the 12v
intake has a side mounted throttle body, this puts the throttle
body up against the firewall when using it in a RWD application and that isn't even inluding the intake or filter. To use the 12-valve intake you need to make an adapter plate to turn it around 180 degrees so the throttle body faces the front of the truck.
- 3. Fuel injection you will have to have the injectors, fuel
rails, fuel system, and wiring harness with all sensors and the
computer or do a megasquirt conversion.
The FE cylinder head from the B2000 will interchange as well as the 2.0L FE 626. There are rumors that the gaskets between these models are different and that if you use the wrong one you will cause an oil starvation problem this is FALSE. Both head gaskets for the B2200 and B2000 are completly compatable between eachother and any differences, if any, should have practically no effect on anything. Both of these engines do have an oil restrictor press fit into the block which regulates the amount of oil reaching the valvetrain, this is also why the copper ring in the head gasket cannot restrict oil since the ring must be larger than the machined area for the pressed in restrictor. This restrictor may be different between the B2000 and B2200 since the earlier B2000s had mechanical rocker arms which require less oil. This may mean that putting hydraulic rocker arms on a B2000 that had mechanical on it might cause an oil starvation problem up top. On the other side putting mechanical arms in an engine with hydraulic may cause an oil errosion problem because the mechanical rocker arms have less and smaller oil ports causing the excess oil to build up pressure and erode the metal. Neither one of these have been proven but could be very likely, in order to check the restrictor size one would need access to a small hole pin gauge set and a block with the cylinder head removed.
Also the cylinder head
from the Kia Sportiage is rumored to interhcange Kia used the
B2000 block for the engine. If this head does work you will most
likely have to swap everything above the deck of the block
including the fuel and computer system. You will also have to find
a timing belt that will work.
Camshafts:
All of the 8v camshafts from the F series blocks should be
interchangable between cylinder heads as far as I know. The only difference that is known is some camshafts, mainly between mechanical and hydraulic types may have different ramp profiles although all the numbers are the same.
Differential:
Some forum members have discovered there are some different differentials which will bolt in with sight modification. Apparently RX-7 differentials will fit, the long pinion versions require a shorter driveshaft to be made at the least. Forum members have also swapped in 1st gen RX-7 differentials. In both the sought after feature was mainly LSD. Miata differentials may also swap with some pesuasion. I have a 3.308 ring and pinion set from an 82 B2000 and know they will swap but need to be installed in the original differential housing on the B2200 or newer B2000s. The 3.308 although a great ratio for may V-8 swaps wanting to keep the stock rear end lacks LSD to make it practical for high output applications.
Valves:
All intake and exhaust valves between U.S. model 8-valve heads for the F blocks should interchange.
Pistons
Pistons in all the F2 engines are the same, they have 3 valve relief cuts for the 12-valve heads. When installed with an 8-valve head these are turned around so that the single exhaust valve relief is on the intake side. I'm sure Mazda decided the trucks where not worth the cost of having their own piston made and probably found that the 12-valve designed piston worked better turned around with the 8-valve head. Pistons from the FE B2000 should also interchange because the bore is the same and likely the clearance height as well. Pistons from the F2T are also interchangable but have a lower compression for boost application (not like it had high enough boost to need them).
Wrist Pins
It is likely all the wrist pins with the above listed pistons are interchangable. I do have some wrist pins here which all came out of or where ordered for F2 engines and have found that some have a thinner wall thickness. I do not know if all of the ones I have are from Mazda or if some are aftermarket, but I do know that the lightest wrist pin I have came with an OEM Mazda piston I ordered.
