How much horse power does a stock 1989 Chevy Cavalier Z24 And what options would you have to increase horse power?

Answer 1

put a nice shiny muffler and that will add 25 hp and 14ft lbs of torque not sure how many ponies you got. but if you want more you can try a performance rebuild. port and polish your head, header and larger exhaust, high compression pistons, bigger cams. the sky's the limit. you can even buy superchargers for you're car. check out import performance parts, alot of cavy stuff. A stock 1989 Z24 has about 130-140HP at umm I think 4500 RPM and about 145-150lb torque at 4500 RPM. More torque than power. I found that pretty cool. To mod up your Z24 is kind of hard. One reason being that the car was made before 1990. Finding parts that you can install are hard to find. Easy mods would be like a basic tune-up. Sparkplugs, all fluids, manifolds, cool-air intake, exhaust. Junk like that. your pushing about 115 at 3400 rpm, improvement? pull that bad 2.8 out and drop an 00+ 3400 motor in *alero* *grand am* etc. tranny will bolt in, have to make a custom motor mount, change the injectors from the 2.8 into the 3400 and buy new throttle cables. THERE ARE NO BOLT ON SUPERCHARGERS, TURBOCHARGERS ETC. all custom made. check out www.v6z24.com TONS OF INFO well i got a 89 pushing liek 200 horse bone stock motor this is what i did hypertech chip 165 thirmstat stage 2 clutch racing flywheel 16 racign wheels custom made cold air intake raised the voltage up to 15 volts msd ignation msd coil packs accel 8.8 race wires coustom made split fire plugs hi flow cat and flowmaster mufflier and the car still makes it through ct emishions but the exhaust and intake are about 130 debicals have gotten 2 tickes so far.. my new plans are rugh idle cam new rockers cast iron head forged pistons .030 over comaro 3.4 intake and throtle body modifuyed bigger and rewired fuil pump everything pored and polished and port mached headers wich were never made for this car ony fo rthe motor custom y pipe 2.5 exhaust all the way back and race computer and race axels that will give u about 300 horse if u want true power put a turbo and get everytihng coustom made
