I just finished and fired up a low budget KA24e-T track (lapping) build last fall!  Great fun ....stock block, log manifold, Z31 turbo..used E-manage.  ...no intercooler.... yet! ( have a ebay used rb IC sitting in the wings)  Stock ECU and injectors should run about 6-7psi..... 
  
Invested a total of $350.  At this point I plan to run as is just to see what happens.  Then the intercooler injectors and such will go on. 
  
Current goal is 200-225 hp.  Final goal is 300hp. 
  
The early cars were non-OBD but if you find a Stanza ECU its a diect plug in and OBD capability can be had.   
  
Great econo fun....first lapping day is comming fast for Mosport in May! 
  
Just picked up my used ebay RA1s from a spec miata car,,,,even the tires are heat cycled! 
  
Sorry will stop the rant now.....got carried away.........   ...........  my bad.....
