Hey guys, new guy here.
I've been loving my '85 RX7 for 8 (brothe had it for 15 years before me) years now, and the time has come for me to replace then engine.


But I have to save up first.


So here is my problem:
I'm looking at putting a '86-'91 13B Turbo into it (with ECU, Tranny, and all other essential parts), because it's almost impossible to find a rebuilt 12A for a decent price. My biggest concern is how hard will it be to retrofit the engine into the bay, or will it be a direct bolt-on swap? I do understand that the fuel tank will need some work, but I'm not to worried about that.

One thing that is really bugging me is will I need to replace my rear axle to accommodate the power and/or the new drive shaft?

Thanks for the replies given.

 

Never done it, but I understand the front housing has to be replaced or a different way of mounting that front part to the frame has to be fabbed up...Mazdatrix and Racing beat prolly have good stuff, but let's hear from the FI gurus here who have done it to set me straight...
