hey everyone, my buddy has a 200sx and hes puttin an sr20de into it. hes looking for a rebuild kit for it cause its got like 60K miles on it and he doesnt know how the previous owner drove it. he got the motor for free and hes just going to put some performance upgrades on it.
any suggestions on what he should do or where he should go to get a rebuild kit for it.
any help would be greatly appreciated.

Thanks
