A friend of mine wants to swap the engine out of his RSX (not type S or anything) with something better, and I was wondering if an NSX would be possible? I'm also wondering what the stock NSX engine #/code is.
Any problems you guys forsee? Would it even fit? Any help would be appreciated.

 

The NSX engine Code is a C30, or C35. This has come up several times before, The NSX engine is not a practical swap in any other Honda product. A C30 is about 2X the width of a K20. If he want's a motor swap for a RSX, keep to the same engine family, the K series.

 

Hmm What about a B18 or B16? Still better to go K series?

 

B series motors and transmissions rotate the opposite way, and mount in the chassis the opposite direction. Stick with a K series. It's a better platform than the B motors. Why else would Hasport be making K series swaps to EK Civic chassis that came with a B or D series?

 

NSX engine spins the wrong direction from the K20 if i remember correctly.

tell your friend to use forced induction on the RSX, but it has high compression like the F20C, it won't respond too well.

he bought the wrong car for going fast in a straight line.

 

....not to mention the massive understeering issues due to the additional weight.....

 

there are 300+whp NA rsx's running around that rev higher than 9k

 

much better off to go with the k20a2 which responds well to mods. The nsx(c30) thing has come up a million times on millions of boards and I have yet to see it done, im sure there are ones floating around out there, but is it really worth putting that much money into an rsx, which would most likely be un-sellable the rest of its life?

It'd be cheaper to just build up the K20...
