Opinions on car I'm looking at on CL

I was interested in this S14 I saw listed on craigslist recently. I texted him today asking the following questions.

6 speed transmission or 5 speed?
Any VTC issues in the past or present?
Ever spin rod bearing?
Motor blow and need rebuild?
Did you build it or did a shop?
Do you have receipts for the parts on the car?

He messaged me back " 5 speed. No. No. No. Shop. But don't have receipts. Previous owner did the swap.

I reply " Still have contact info of previous owner? Know what shop built the motor? Any proof at all of engine internals?

He messaged me back " I do have the previous owners contact info but he hasn't responded lately."

My reply " I'd be more inclined to make an offer if there was proof of the engine internals."

His reply " Yeah unfortunately I don't. but you are free to check it out."

First off I'm thinking might be a sr20 from a s14a not the s15 since it has a 5speed transmission unless the 6speed was swapped out for one. Things seem a bit fishy here. Should I just not even bother and wait for something else to pop up? I feel like I could be passing up a clean car or just get completely fucked.
