Ok I know the 93 240sx lug pattern and an 84 300zx lug pattern are the same. My only question is, is the offset and everything the same too? Can I order wheels for a 93 240sx for my 84 300zx n/a and the 240sx wheels fit right on with no problems?

Google the 240sx offset and compare.

 

basically no. 240SX is mid offset (hard to find wheels). Some FWD wheels fit it.
Z31 is RWD offset. Your 4-lug version is hard to find in +30/+35 5-lug would make aftermarket wheel hunting much easier.

 

posting offset numbers without posting wheel width information is worthless. Depending on the wheel width, the offset will have a wider range. But if you really need a number, stick with the center offset. In the case of the 84/85 models, it's 21 for the front and 34 in the rear.
