  1. Im no expert but I would have thought the cylinder diameter is going to be different
  2. thats what i would like to know is the diameter the same or diff. and if all the ports will line up and if it would cause the HP or anythinbg else to go down or up
  3. ok there are two ways to change the capacity of an engine.

    1) increase the bore / cylinder diameter

    2) increase the stroke that each pistion travels in the cylinder

    Theoretically if the two heads have the same size diameter cylinders then yes they would work, however the longer stroke may cause the pistons to impact with the cylinder head - which is not a good thing.

    if you can find out the bore / stroke of each variant you will be able to decide if fitting the 2.5l head is going to work or not
  4. and one last Question a turbo charger pushes air into the engine using the exhaust?
    and a supercharger uses a belt?
  5. 2.5 OHC

    A stroked (by 7 mm) version of the 2.3 OHC Ford Ranger engine appeared in 1998. It also used higher-flow cylinder heads for better intake and combustion. Output was 89 kW (119 hp) and 202 N·m (149 ft·lbf). It was replaced in 2001 by the Mazda-derived Duratec 23, but Ford Power Products continues to sell this engine as the LRG-425.

    The Ford Pinto used the OHC version, a 2.3 L (2302 cc) unit introduced in 1974 which has a 96.0 mm (3.78 in) bore and 79.5 mm (3.13 in) stroke. This version lasted until 1997 in various guises. The earliest units produced 66 kW (88 hp) and 160 N·m (118 ft·lbf). This engine has also been known as the Lima engine, after the Lima Engine plant in Lima, Ohio, where it was first manufactured (it was also later manufactured in Brazil).

    from what ive read here it seems like it would work
  6. both supers and turbos are FI so they force air into your engine (called boost) how many pounds of boost you are pushing depends on the total power added to your powerband. supers boost constantly(well theoritically) and therefore you have that powerband from 1rpm to xxxx rpms(depending on how high your tach goes) and turbos have to spool air before it is forced into the engine, which results in a concept called turbo lag. so after a certain rpm your turbo will force air into the engine. there are ways around turbo lag(or should I say, minimize it.)

    as far as finding out which system is better for you depends on what kind of powerband you want and where you want the power really...

    for example, i have a super on my gt500 therefore I boost constantly(about 11.5 lbs) resulting in 540 hp at the crank and 510 lbs of torque of constant power. my brother has a turbo(pushing 16 lbs) on his evo VIII and he pushes a little over 415 hp at 3750 rpms.

    hope this helps and wasnt too much info.
