First NSX/Legend engine swap (LegeNd-SX) Now running
 

Enjoy this wonderful project that took me about 2 years to plan and another year to build it.

thumbsup: 04/july/2008 UPDATE
I thank everyone in this forum for their support words about this special and difficult project.

I will try to do my best to keep you updated about any progress done, but anyone that has being interested in the idea of doing a NSX engine swap in any Legend knows that yes all Honda c series engines (c27a1, c27a4, c30a and c32) are very similar and that maybe some are swappable with a lot of MAJOR changes, lots a custom work, lots of money and spare time to do the work…well I hope I will able to do it.

Today I took some preliminary dimensions of both engines mounts and mount locations, and yes there are discrepancies on size and locations, but this can be fixed by creating custom mount brackets on the G1.

Second obstacle I see right away is the transmission linkage facing wrong way and this has to be fix ether by creating custom linkage or by reversing the operation of the gear switching arms on the trany but I still need to do a lot more research on this if not possible will need different trany will see…

Yes C30 bigger, taller, and wider… will fit G1 engine bay? Yes because I remove all these accessories that are not necessary in a drag car and there is more room that the normal stock G1…

If anyone knows anything about switching or inverting the direction of the linkage on manual transmission or knows some or shop that might be able to help with work please let me know I will appreciate the help…

I will update later…

07/09/08- Engine is ready to be removed from NSX all wire connection, hoses, brackets and supports removed... update later...

Good luck with that shifter linkage. :rolleyes:

If you actually pull this off, well, I'll be shocked.

Yes, linkage will be a problem but it will be possible... there is some other swaps that they had about the same situation and they end up with a good setup...

here is a pic of fwd to mid engine swap custom linkage...

your making awesome progress!! one question how is the nsx's gear shifter hooked up? is it a cable linkage kinda like on an 90-93 accord? or is it actual linkage like on a da integra? this thread has really got my curious on how your going to get the tranny to function properly. keep up the great work, hope it continues on a good note!

EDIT:nevermind I just noticed that it stated about the linkage earlier in the thread. sorry for the dumb question.

:confused: :confused: The NSX shifter is a cable type and we are going to swap to the G1 the linkage on the tranny has not being designed yet but we have at least couple of ideas on the custom linkage...

Thanks again everyone for your support!!!
Today i had to make some cuts to increase clearence around engine and transmission...
Here are some pics showing cuts to main front support, front body backet, one small cut on the bottom of tranny to clear the front support beam and one more on the body on top of the tranny...

These two mounts are exactly on the same locations as the G1 engine mounts (but different)
