Hi,

Well I've been looking into the 20B FD conversion for some time but still have some questions left. ANd cant find them in the same thread.

What is all needed to convert to a 20B, in my opinion following should be done:

20B engine block, can be made from 13BREW parts except eccentric shaft, does the 20B still need the counterweight??

The 20B will bolt on to the FD gearbox, however when lots of torque comes into play you might consider a different gearbox.

Engine mounts? No solid info found here, I think it also depends on the subframe, however I read something about FC mounts??? If someone has some info, please post.

Subframe, Ive read alot on the subframe, but Is it really necesarry to convert to a custom subframe, Ive also read that some people used the original frame but then there is little to no clearance for the steering rack, this will mean steering rack moval or a different steering rack, FC steering rack?

Does the Gearbox move backwards or does it stay on its original location?

Exhaust manifold, custom made or ordered from japan for a COSMO?

Fuel rail, both primary and secondary, custom made or ordered from japan for a COSMO?

Oil pan, will the standard oilpan clear with the FD subframe, or do you need to go with a dry sump system?

If anybody is willing to shed some light in these things it will be much appreciated.

Control system, Microtech and haltech are available as are some others.

Rogier
