Hey everyone. I'm coming from a rotary (FC). This will be my first personally owned piston car so I have a few questions. I'm picking up a automatic 95 S14 in the next week or so. I want to swap a RB20 into it. I plan on picking up a R32 front clip to do the swap with. I've done a lot of reading trying to figure out what I'll be able to use off the clip and what I'll need to go to the junkyard or parts store. I have access to a welder so fabrication isnt a issue if I need to. I have a few questions about the swap.

1. Doing the auto to manual conversion, can I use all the pedal parts from the R32 clip or will I need to get a pedal assembly from another 240?

2. In the RB FAQ, people talk about using the R33 crossmember for mounting the engine, but nothing about the R32. Can I use it or will I need to fab up mounts? If I can use it, Can I use the S14's steering rack or do I need to swap over the R32's rack as well?

3. In a RB conversion into a S14 thread, I saw that someone had to remove some of the cover for their throttle cable. Is this required?

4. How big of a issue is the crank collar on these motors? I've seen that some people use aftermarket ones over the stock. Others weld the collar to the crank. Is this safe/necessary?

Thanks in advance for your replys!

Hello, first of all you should have searched before making a thread.

1. You need use pedals from a 240. R32 is RHD.
2. You can use the R32 crossmember. R33 crossmember is for RB25's. You can also use the stock crossmember and make your own mounts. Use the stock 240 rack.
3. Throttle cable needs to be repositioned for a LHD car.
4. Use the stock one.

Well that was quick! I did search, but the RB FAQ thread is about 30 pages long, 20 of it being people talking back and forth.

Thanks for your help, I'll post more questions (I know I'll have more as the swap goes on) in this thread as I go (If I can't find them searching).
