JDMboy i sent you a pm hit me up
CCP while they do know there shit they're prices are astronomical. (ie 700 to install a clutch on my sohc - i would be providing the parts) , as far as Slideways goes almost every s-chassis owner in tri-state area has heard of them and they do solid work.
ive never dealt with Wired but ive heard they do work and they have dyno days like 2-3 times a year another option isnt really north jersey but i have called them with some issues i was having doing a swap for a friend and they helped me diagnose over the phone is Pride-performance but they are in central jersey.
the 2 shops that go without saying for awesome work is ImportDPS and Import Intelligence
both in PA but build solid cars, buddy of mine had a 400whp B13 sentra that was originally built by Import Intelligence.
ive done several swaps with me n my buddies, honda's , and KA's and one SR
i have a 2 car garage and KA or SR can been done in a weekend easily (hell it only takes about 40 minutes to pull the motor) i dont mind helping fellow S-chassis owners.
if there is enough interest i'd host a garage/wrench meet at my place
