Wow! I did not get that out of that post at all. What I read was that he killed his 10K RPM 2ZZ after trying to race it a whole season and has since switched to the K24 which he has broken several times now. He states that the 2ZZ is a wonderful engine and is "much more reliable" and bemoans the fact that the 2ZZ is not a larger displacement engine. That seems to indicate to me is that the reason he went with the Honda was because it has more performance potential due to larger displacement but it is not as reliable thus his "&*^ K24 " curse at the end of the post that he has to fix the K engine again.
I posted that because Honda reliability has been mentioned a few times as a reason to do the K20-24 swap over the 2ZZ. At least in this racers experience, that has not been the case. I have also outlined the other drawbacks to the K into MR-S swaps. In my mind, there is only one advantage to that swap and that is more HP potential due to increased displacement. You have to put that goal above all else and let it outweigh all the advantages of staying with the 2ZZ swap. I might be able to do that for a track car but there is no way I would do it in a street car that is filling the same role as a street driven FR-S.
The FR-S has five advantages over the 2ZZ MR-S
1. More space which makes it easier to live with on a daily basis
2. Warranty (unless you stupidly mod it away)
3. Better styling (yes, in most people eyes it is prettier)
4. Better aftermarket support
5. Higher top speed (better aero)
In every other performance category I can think of the 2ZZ MR-S will win.
See how I tried to steer that back to the original topic?
