Digital Cluster And Accelration Boost

Hello Everyone I am the owner of 1985 200sx Xe non-turbo. I recently had the engine rebuilt and I am seeking help for adding boost to my accelration. When I press on the gas pedal the car accelrates fine but it seems like the air flow is being slightly restricted. After pressing the gas pedal for a few seconds it seems that whatever is blocking the air flow moves and then my car really accelrates, can anyone tell me what this might be. I have recently had the exhuast manifold gasket replaced, catalytic converter and some pipe work done. I also think i need an intake sensor but can't find one. Now the other problem is i have a digital cluster and my speedometer doesn't work but it lights up fine the oil temp and other things seem to work well but the speedometer and odometer are failing can anyone tell me if there is some sort of relay or sensor I need for this. Please help and give instructions or direct me to places I can call or go to in order to get this fixed. I can do some of this work myself but I would need detailed instructions. Thanks for the help and advice.

digital cluster i can help you with check the product advertisment section for my thread on reconditioning digi clusters.

sluggish acceleration??? timing to retarded i dunno we'd have to look at it. then again dude its a ca20 theyre not that quick to begin with usual once they get going theyre fine but theyre shit for acceleration. i mean did u notice the problem after they did the work or has it been like that since u owned the car?

and what intake sensor do u speak of post pics if ur unsure what it is so i can attempt to help

dood ur in socal u need to make it to one of our meets dude.

run 91 octane and advance your timing a bit and u feel a bit more pep outta the ca 20. just loosen the nuts holding the distrubtor and turn it to the right to advance the spark. it will feel alot better. as far as the sensor light it just comes on every 45,000 to remind you to get your car serviced or replace the 02 sensor its nothing to worry about. there is a box under the dash with a button u press that and it resets the light actually u can just remove the bulb that warning lamp serves no purpose. hope that helps

edit: any more q's just pm me or post up.  lol my car was the same color is yours! is ur car a hatch or notch  where in cali r u @?

if that "boost" you describe starts at almost 3k rpm... id say thats because the torque curve is on its way up... i have no bottom end idle to 2700 or so is lacking... at 3k it pics up and youve started the decline at around 5.45k

also is your ac on? i have even less low end with it robing 10hp from my already wimpy 93.

but if it is a time delay... TPS might be wonky? idk thats where all my engine issues have been...a screw backed out a bit and the tps shifted causing a lumpy idle stalling sputtering, slow accel til 4k exct
