how much?

What is the max hp that we can get out of a zx2? And will it be hard to install it?

same as a focus, its almost identical

i dunno it depends on what you keep and what you toss. if you disable the VCT < if thats what you have i hear you can get substantially higher numbers then if you keep it... granted there is a too much category where you stop having a street car and start having a strip car... so if you specify what you are looking for we might be able to help.

full boltons, good condition motor and goot SCT tune With VCt will give you about 145hp/142tq at the wheels. thats roughly 175 crank.

there is also that role of thumb on transmissions: manual is about 25% (?) reduction, and auto is about 40%

manual = 17% for a zx2/focus

sweet, 25 was an average. is there a way to bring that down? i know on auto's you can find more efficient torque converters (ussally smaller) and shift kits help too... but thats more on putting power to the ground.

15% is the general assumption, its 25-30% est. for auto's

for a manual the onlything you can do is get a lightweight flywheel, and a good strong/lightweight clutch. and that wont help a LOT just a small bit. but a tranny in good shape is always better then a beat one.

i know there are single, double, and even triple clutch plates... but i have yet to drive a double plate clutch... would it help? or is it just different?

i believe the centerforce is dual, if its is, its just heavy lol
