i been thinking about this for awhile. question is what is different between them? show or tell me how are they different? i search for this topic and nothing came up.

 

jdm gsr is type r? i think type r intake manifold cylinder head is different than gsr

 

my bad jdm b18c1 vs usdm b18c1 intake manifold

 

I don't know, so I got an S2 im.

 

i know different for the gsr intake manifold and type r intake manifold. the reason i asked the question is smogging the car

 

because the two gsr manifold look the same, but if i smog my car with the jdm version would the smog tech will notice the difference in the two

 

need more input

 

Are you sure there's a difference? If not, then it shouldn't matter which one is on there, since they would be the same.

 

It never ceases to amaze me how lame the California emissions laws are...

 

well im planning to buy jdm b18c1 motor switch out parts from my usdm motor like intake manifold exhaust injectors and so on. that why i asked if usdm or jdm intake manifold are the same or not

 

come on peeps you can review this page but you can't respond.

 

i should be the exact same engine, the only thing your going to have to worry about its the b18c stamp and no vins.

 

if the jdm motor you're getting is 96+ "obd2" then yes there is a different. it doesnt have the bung for the EVAP PURGE SOLINOID VALVE which runs into the charcoal canister.

 

also if your car is obd2 the jdm motor wont have the crank fluctuation sensor on the oil pump. so your going to need to swap oil pumps and timing covers. manifolds are the same

 

so basicly i have to switch out evap to put it on the jdm one. i know about the vin number and all that. i planning to take my car low budget smog shop really dont know different honda motor. on the far eastside of town. if i take it(just letting you know im not racist) if i take my to white guy shop they will look for everything. last time i smog my car this smog tech even look at my ecu and was on the phone with the state ref. at the time my car wasnt passing smog. but i fix the problem, i had bad cat and o2 sensor. i pass smog with a build gsr motor

 

my car is obd2a

 

yes without that EVAP purge siloniod the ecu will throw a CEL.

 

Does the jdm one even have secondary runners?

On my friends jdm b18c you could never hear them open like on my usdm engine.

 

i guess it should have the second runners

 

Ull be fine just use us injectors exhaust and ecu

 

and change the oil pump, install the cfs sensor and don't screw up the oil pan gasket install.

also get a new oem timing belt

just had to add that after talking to a guy who bought a jdm R motor, drove it and had the belt skip a tooth 5k later. 13yr old timing belts are dangerous.

 

i all ready bought the parts i need so far

 

im about to buy a jdm gsr motor b18c1 obd2,

what would i need to change if i choose to run the USDM ecu? so far i researched i would have to swap out the oil pump and add on the evap purge solenoid valve, is this correct?


now what if i choose to plug in the jdm ecu instead of using the US ecu, would i still pass smog?

im going to buy my motor from hmotorsonline.com the owner says all i have to do is swap out the oil pump if i choose to run the US ecu.

 

you'll have to swap out the oil pump, add the cfs sensor, use a usdm crankshaft sprocket and use the usdm vtec solenoid along with adding a purge solenoid and tapping it into the vacuum chain somewhere. the jdm itr manifold does not have an evap port

hmotors is beyond over priced on R engines. steve is seriously living in 2003 with those things.

 

not an R motor just regular jdm b18c, would is till have to do all those things? wow that seems like so much work, do you knowsome where else where i can find a long block gsr obd2 96+ motor for better price?
