Thread: hey have an problem understanding

hey what up people i had a lil problem i have an 91 sentra ser come with the sr20de so now what the diff between the jdm an the usa engine please someone help me understand

intake manifold. JDM has no EGR. thats the only differance.

but it that an big diff or no

for performance, it's not a big difference. But if you live in a state that has smog tests, like CA, you will want to have EGR to pass it.

well thats thru here in california is a mess with the smog test i just swap my engine usdm for a jdm high compression and i swap the manifold and the header firs the header you can not used it cause there is no hole for the oxigen sensor or for the egr pipe for be sure the only thing what is the same is the head hte monoblock and thats it
