the sr20 head it`s a lot bigger than the GA, deeper spark plugs. there are two kinds i think of sr20 the high port and the low port, I like the high port, it`s stronger, and not talking about internals, about middle range torque..
i have a nx2000 and i had it for less than 20 hours and the engine threw a rod. now i am looking for a jdm sr20de or jdm sr20det. b/c i hear the block is much stronger. where can i find one that i know will be realible for daily driving and spanking people when i feel the need
