It is almost that time of the year for me where I can put my RX-7 back on the road since the end of September. I am having withdrawls and getting very ansy to put it on the road again. But my question is how much power am I looking at with all of the goodies I have bought over the winter. What I have done is:
-full custom intake arm w/ HKS filter
-throttle body porting and mod
-racing beat header
-high flow cat/ but most of the time it will be straight piped. Only need the cat for
putting it on the road.
-Borla cat back exhaust system
-HKS spark plugs w/ 10mm wires
-And an Apex'I S-AFC
Thanks for any input.

I've seen 189hp at the tire on 89-91 internals, no portwork, stock manifolds, factory ECU. This was on the shops ITS race car nearly 2 years ago.
I personally have 183 whp and a list of my mods are below, please note STOCK PORTS
86' N/A untouched internals. (about 13,000 miles on the clock)
RB header strait back to Borla Cat-back exhaust.
S5 intake manifold set-up. Port matched Upper-Middle-Lower
TB mod has been done. 5th/6th sleeves removed, VDI wired open.
No accessories attached to the motor for the exception of Altenator.
NO emissions equipment is left on the motor. Fuel lines have been re-routed directly to my fuel rail, bypassing the vaccum rack.
running 460cc primary, 550cc (T2) secondary injectors
Microtech LT-8 currently running on slightly modified base map.
I still have another 5-7 HP to be had from proper tuning. I just installed my microtech this weekend and dyno'd the car with the modified base map. I am quite pleased with the results 183whp / 129 lb ft.
Strange numbers i suppose but quite respectable for N/A
