My friend wants to replace his oem damaged ls motor in is 98 integra ls for a jdm ls motor swap for smog purposes. Will he be able to pass smog in c.a? not at reff because his car is all stock and he wont get a ref ticket for any reason so he is just worried about smog. He seams to want a jdm motor swap because he don't trust the junk yard replacements. I think he should be fine but idk for sure.

 

Tell him that jdm motors are illegal in your state. Then tell him that you're his friend and that you're just looking out for him.

 

I actually did! but he seems stuck on a jdm swap, i think he thinks it will have less miles than a local us swap at the yard. he says hes not worried about the reff smog or getting it bared.

 

The engine replacement will be fine.
It will of course need all of the USDM smog equipment swapped from the original engine(Evap purge sol, ect) and functioning properly.
Also the USDM ECU must be used.

its simply a replacement engine, and should not need to be BAR'd

 

this

i would also stamp a 1 after the b18b just to be safe

 

Absolutely,
Most ref's out here in California will allow JDM swaps,
just as long as all emmisions related hardware and systems are present and operating correctly under control of a USDM ECU, injectors, catalyst, ect.

Anyways no need to worry OP's bud, as you are just replacing the hardware aspect of the engine, cause original conponments must be used to pass.

 

Thanks guys! yea thats exactly what i told him! i just wasn't 100% sure if he tranfered all his emmision related stuff it will pass. and i also told him he has to stamp a 1 but its kinda shady lol..

 

I wouldnt stamp it personally.

A JDM LS will def pass,
mechanical wise, the only difference between the two would be cam profile, compression. which I think are not much if any difference with the two LS motors.
The DOHC VTEC motors have a nice little bump in compression, but still pass with correct emissions related devices functioning properly

And remember, if you ever get a whiney, *******, assuming smog tech that is over examining your vehicle.. just go down the street to the 20 other shops that dont GAF. It is rare to find techs that actually check VIN's and follow up on the proper procedure and catch little issues.

 

yea man your absolutely right! i had my gsr smoged years back and i totally forgot i had a aem fpr on but the smog guy didnt even care to say anything lol where as theres a few out there that get all **** about the smog!

 

u need to put a type r in that hoooeee

 

I hope you find this usefull.

I had a local guy take my B18B1 out of my 2000LS w/ auto and install a JDM 1999 B18B that I bought from hmotorsonline (the head was stamped "99").

The mechanic told me that my B18B (hmotorsonline motor) came out of a Civic and a few parts would be needed from my USDM engine.
He offered to splice/cut some wires on my ECU, to avoid any CFK/P1337 engine codes.

I didn't know which helpful check engine warnings (codes) I might not get in the future, if I let him splice and cut some wires on my ECU harness.
He did not cut any wires.

He took the original engine B18B1 out of my 2000LS and these are the parts, from my USDM B18B1, which were needed to get rid of the CKF (P1337) code.

oil pump 15100-p72-a01

oil pump pick-up strainer gasket 15221-pw0-s01 .......(I bought a new one)

oil pan gasket 11251-p30-004 ................................(I bought a new one)

tdc sensor 37500-p72-a01

timing belt stopper plate 14535-p72-a00

lower timing belt cover 11810-p72-a00 (needed to fit over the usdm oil pump)

timing belt cover bolt 90007-679-000 (civic only uses 2 bolts)


The Civic was right hand drive, so he needed to re-use my original USDM:

complete and uncut original USDM engine harness
power steering brackets 56997-p54-010 (upper) & 56994-p54-000 (lower)
timing belt cover insulator 56999-p75-000

intake breather pipe hoses 19527-pr4-a50 & 19528-p75-010 & 17153-p2t-000
the intake manifold & sensors & throdle body (for usdm emissions)
crank pulley 13810-p75-013 (the civic's was bigger, in diameter)
engine 3-post mounting bracket (left) 11910-p72-000 (the civic uses a 2 post bracket)


He also needed:

intake manifold gasket 17105-phk-004 ...........................(I bought a new one)

exhaust donut 18229-sh3-x30 .......................................(I bought a new one)

header stay mount 18213-st7-a40


Of course he did a complete timing belt service:

timing belt 14400-p7j-004

tensioner 14510-p30-003

belt adjuster spring 14516-pr4-a00

water pump 19200-p75-003

Thanks man!

and no! a ITR swap would be senseless.
