Default best motor for autocross

i have a 95 civic ex with the factory d16z6, i want to set the car up for autocross and DO NOT WANT turbo, nitrous , ect. what motor would be the "best bang for my buck" and will actually yield gains with basic bolt-ons? im wanting around 140-160WHP. Any suggestions would be appreciated.

b20 for bottom end but i heard they dont like to rev so much, maybe a b18? vtec or no vtec depending on your budget.

short geared b16 tranny to help keep the revs up.

I would keep the D, put a turbo, and spend the money saved for an engine swap on suspension rims and tires but that's just me

Best bang for your buck most likely would be a B16a3 with intake, header, and exhaust. You should easily reach your target.

Motor often has little to do with going faster in Autocross than driver skill / suspension modifications do.
Ive kept same times with Dual cam motors with my singlecam one without a problem all this last season.
Your best bet for AutoX/DD IMHO would prob be like a gsr/itr, something with some nice low-end pickup (b20 too if thats available) and short gears. Makes great for sprinting between cone gates nad sharp turns.

Eh I would personally go with something with more displacement. A B16 doesnt have much torque. Just my 3 cents

it's a honda... you aren't ever going to get an even broad powerband like you want. most everything is top end with these motors.

with a 5k budget id do the b16 swap and build the motor. maybe cams, intake, header, ignition, and some tuning. a regular b16a is not that impressive, but if youo have extra cash you can make a strong/powerful motor.

how experienced are you? only reason that i ask is that autox really depends on driver skill and you wouldn't want to be in a different class because of swaps and whatnot.

for instance, when i had my R i went autox'in and would get beat by celica gts' with suspension and tires alone. having a b18 in a civic would surely make controlling the car much differently with the added hp.

if i were you, i'd add some boltons to the z6 and keep it simple. if anything drop a grand on the suspension. that's just me though...

i understand you wanting a swap though. hell, i'm putting in a b18c1 soon.

I second^.
any type of motorswap will put you in a different class. check out the rules and regulations for each class and decide where you want to compete in.

My friend had a bone stock dx hatchback with azenis on the stock 14' steelies and would always leave my *** after a turn or two (back in my back road carving days). I had the regular i/h/e and suspension and yet, there he went. at the same time, other people already thought i was driving fast.
