for the vtec swap we have a diy section, all you need is a vtec head (d16z6 or d16y8)
a vtec ecu (p28) and some wire to run 2 new wires to the new ecu. and of coarse a head gasket, intake gasket.

for turbo we have tons and tons of info on it. look in the turbo section. but you will be spending around 1500 or more depending on where and how much you can find your parts and also are you going to be doing the work?

for the auto to manual swap we have a diy on it also. you will need to find a 92-95 manual civic and pull the parts from it.
manual trans
manual starter
manual flywheel
clutch kit
manual trans mounts
clutch pedal assembly
manual brake pedal
shifter
shift linkages
clutch slave cyl, and master cyl
clutch hydro line.

 

I believe all the parts from a 96-00 civic with a SOHC (everything except the SI) will fit for the transmission swap, also.

 

i have a honda civic 2000 Ex (automatic)to be honest i dont know crap about my car, i dont wat engine i have i dont how much HP ... i dont know s%&^ well the only think that i know is that it takes me alot of time to go from 1 to 60 mph even kia cars past me some time........ after i get 60 mph now that i when it really go fast but when it gets to 100mhp starts to shake alot n to kuff kuff ... now i want to put more HP i to try to put it to Manual well what you think i should do i got 5G's to spend .... so wat can i doo wat i cant do ...... someone told that i could put a Acura engoine on it i wiil help alot but like i said on the first line i new on my car i really i dont know to much about cars prob only how to change oil (engine, tranmission ,regular stuff) Plsss helppp

 

well if you not in canada you have the d16y8 (vtec)engine and is a great engine, first off do you have a check engine light on?

 

i do have the engine light on how u know

 

well you need to find out why the cel is on and fix the problem, your civic has a vtec engine and vtec will not engage if a cel is on, the ecu puts the motor into limp mode.
therefore your car doesnt have the power it should.

P0122 Throttle Position (TP) Sensor Circuit Low Input

few months ago i change my TPS for a new one ...now this code come when i scan it.......... try to reset it but the engine light go off n comes on back again in few seconds i dont know wat to do ??????

 

You either got a faulty TPS (you'd be surprised how often bad sensors are sent out) or there's a load somewhere between the TPS and PCM(ecu). More than likely it's a bad sensor, not plugged in the whole way, etc. though.

 

by any chace u know anyone or any store that sell TPS that can really work ...

 

Any parts store (Advanced Auto Parts, Autozone, O'Reilleys, Carquest, etc) should be able to get you one. The likelihood of getting two bad sensors is fairly slim, so if you change out the sensor again and the light comes back, I'd say the problem is somewhere else in the circuit.

Also, you could go to a Honda dealership, but you're going to pay cost plus a huge markup. Yes, the quality is better, but the cheap ones will work just as well as the oem one.
