In my experience none of these things are sold as a kit. The closest to a kit you'll find for the NSX is from Toda and SOS. Comptech can probably put something together for you also. HQ Engineering has their own flavor as well.So is it recommended NOT to go 3.8L then? Any reliability issues? Also can someone let me know the parts for the kit to buy from Brian Crower?
In my experience the frequency of rebuilds increases the higher in displacement you go.
