ok forged closed deck 2.1 2.2 2.3 stroker kit etc what does it all mean i have sti gdb so confuzzed lol already running 450+ on standard internals so help please

 

Gc8 CLASSIC GDB newage !

 

which bit are you on about

forged is stronger metals used in your pistons and conrods
stroker means the piston moves up and down a longer distance and because of that you have a larger capacity hence 2.1 to 2.3 strokers, the 2.1 being the capacity of the engine
closed deck as opposed to open deck means there are better supports holding the cylinders in place

 

As above the 2.1 is a 2.0L block and 2.5L(79mm) crank with a different rod
2.2 is the block from the 22B or early legacy, which can be made into a 2.35 using the crank from the 2.5L engine and different rods, And so on.....

 

Did you do the mods yourself or buy the car like that ?

Only reason I ask is cause if you'd done it yourself you might of been recommended a 2.1
