I found a JDM B13T front clip for 1300.00 minus shipping. I found the supercharger kit for 3649.99 minus shipping. I want to put one of these two in my 87 RX7 N/A. Of these two which would be cheapest and easyest, with the most potential?

 

um turbo... turbo will always be better on a rotary engine, go turbo... supercharger doesnt net as big of gains as most people would think, when turbos can go insanely high in gains depending on what you do

 

if i were you, i would try to find a cheap, beat up t2 for sale..... if you go w/ a front clip, you dont get everything.... to do the job right, you need the motor, trans, d-shaft, and rear end, not to mention the harness and ecu (which does come on the front clip)... if you just put the t2 motor in, your likely to grenade trannys, d-shafts and rear ends if you put and kind of power mods on it!

 

The 13BT front clip has the wiring, ECU, and transmission on it.
You still need the driveshaft, rear diff and rear axles to complete the swap.
Also, the wiring harness and ECU are on the opposite side, and a bit of custom wiring work needs to be done to make this all work with a LHD US-spec chassis.

The supercharger kit is built for your car, so if you can afford it, it would be a much easier install.
