So I just bought a 92 Civic CX with a GSR swap in it, is there any way I can tell if the swap is a JDM b18 or a USDM b18?? Thanks!

 

my motor is usdm and i believe the engine stamp on usdm motors have b18c1 the jdm motors have no 1 at the end. other than that there are also vin numbers on the block and tranny. another thing is the compression usdm is 10 to one jdm is 10.6 to one or sumthing. hope this helps.

 

Yup...
b18c = JDM
b18c1 = USDM

 

weee! Thanks guys. Guess I've got some JDM love in my hatch!!!!

 

hahah jdm love is good...but watch out for the cops and smog. they hate love.

 

Yeah, I hear that....lol. I had to get an exemption for emissions here cause it failed 3 times.

So now how can I tell if the tranny has an LSD or not???

Anyone???

 

those jdm gsr motors are sweet. almost like a Type r less cams and the longer manifold. good motor for street strip with a good set of cams and all the other goodies. I just dynoed a stock one and notice a big difference from a stock eg airbox to a K+N cone setup. now for some more playing. oh also I got this one to pass cal smog referree.

 

it will have LSD stamped on the tranny

mine is stamped b18c3

 

man the bar sticker was a pain in the a$$ to get. i failed the emmisions so many times.....i was high on hydrocarbons. i always thought my gsr ran rich......i also had a knock sensor that came on and i never figured out why?? i just got a p28 and said f it. anybody else have the similar probs with their gsr set up and the bar?

 

how can we tell between the jdm type r motor and gsr motor if they both say b18c?

 

Smart Monkey, what did the stock one you dynoed put down to the wheels???
