OK people, I just picked up a 13B powered FB as an organ donor for my RX2 race car restoration. I have literally touched every nut and bolt on a 12A powered car when I raced them back in the early 90's. Besides the obvious injected 13B sitting in the big hole in the front and the bigger brakes/axles are there any parts that I should hang onto and clean up for people wanting to put a 13B into a 12A car?

The car has been a race car for about 23 years so it has a lot of goodies for my old IMSA car. The chassis may be a good candidate for a Lemons car build, it has an old bolt in cage in it but there is a strange crease in the driveshaft tunnel behind the seat area. I suspect the car may make 4 tracks in the snow if it ever snowed down here. I'm having visions of a carbed V8 sticking through the hood of a car covered with indoor/outdoor carpet...

 

the crossmember,the mounting points are a little more forward compare to the 12a crossmember,which makes up for the longer 13b.

 

So the cross member is specific to the 13b car, cool. I know the oil pan on the 13B is also specific to the older cars, is it the same as an RX4 unit? What about the motor mount plate, it looks a little different than I remember, maybe a slightly different bend pattern.

So, it looks like the cross member, front cover, oil pan/pick up and motor mount plate would make someone able to put a 13B in a 12A car.

Next question, the big bearing spindles and the older sized brakes, just a different inner bearing? I have some really slick hubs with replacable rotors for the RX2 that use a widened RX3 caliper and I also want to keep the smaller bolt pattern of the RX2.

 

GSL-SE also has larger fuel lines, and a tank with built in Fuel injection baffles.

 

That stuff is long gone, it has a fuel cell and about 100' of braided hose for the various plumbing systems.
