Fd vs Fc lim

[memski]

Just wondering what the differences are between 2nd and 3rd gen lims? Got hold of a modified 13b cosmo inlet which has the upper half of the cosmo lim grafted onto the lower bit of the fc lim. The ports have drastically been shrunk on the lim, and I haven\'t had a chance to compare it to a stock fd lim but they look very small on the engine side! Not much room to port either.

Any thoughts guys, will get some pics up later.

The FC LIM wont fit an FD block, the Ports are a different place, that people retain the FC LIM.   The FC LIM has bigger runners at the bottom of it that an FD, which get very small.

Saying that, Ant at Stert has run over 500 bhp at the wheels on stock manifolds so i dont see a need to change them.  I tested FD and FC UIMs back to back on the rollers and there was a tiny difference.

Cool, thanks for the info.
