hey as the title implies I picked up a 91' RX-7 about an year ago, it had the N/A 13B in it and I have since swapped it for a 13B Turbo but I'm waiting on some additional parts to get it going, is there anyways without pulling it apart to see if the thing even runs? i was told it runs good and has low miles but you can never tell with people these days you know??

Another question I have is what are the capabilities of the stock turbo and fuel pump, if I were to increase the boost a little bit will the fuel pump be able to keep up or will it need to be upgraded and how high can you turn the boost up on the stock turbo? I'm thinking of going with a little bit bigger turbo in the future but only slightly because I still want it to spool quickly but be able to push a little bit more power to the wheels than the stock setup

Also, I've got the stock down-pipe on it right now if I go cat-less is it going to boost creep a lot or will it be okay?
