well i am looking in to getting a Turbo II. im new to the online rx-7 scene, but have had an rx-7 since i was 15 (79 12a all original). i want to be in the mid 13's and still have a very streetable car. how should i go by doing this? are there any major online retailers or stores for the turbo 2 cars? how much do you think its gonna cost me to get in the 13's? thanks. oh yeah what things should i look out for when buying a turbo 2? or 2nd gen RX7's in general?

 

The previous owner of my 88 TII had the following mods and the car and managed a 13.6 at sea level. The car also managed to blow two engines because it didn't have any fuel system upgrade or wastegate porting, so I would add these to your list. I simply subtracted the VBC, added the FCD, and the car runs great although its 13.6 days are over unless I add the previously mentioned fuel and wastegate mods.
HKS Super Mega Flow Intake (Personally I like K&N better)
Racing Beat FCD (Fuel Cut Defenser)
HKS VBC (Variable Boost Controller)
Center Force Dual Friction Clutch
Gutted Pre-Cat (Expansion Pipe)
Custom Straight-Through Cat-Back Dual Exhaust (No Mufflers)
Auto Meter Ultra-Lite Pillar-Mount Boost Gauge

Here are some of the many 2Gen parts suppliers on the net. Be sure to check out the excellent mods descriptions on the K2RD (the 2nd link is to their old site) and Mazdatrix sites. Also, the Racing Beat catalog has good tech tips, although it doesn't cover the 13BT very well.

Here is a good link for what to look for when buying a 2Gen. It addresses an NA, but the TII isn't much different.
