Toda Sports Injection Kit + Dry Carbon Surge Tank + ISCV kit
Toda Toda Toda time. Toda Sports Injection kit for AP2 S2000! This is something I have always wanted to do on an S2000, and information and other things started to align where I think it is a real possibility. For the F22C Toda provides the same fuel rail used for K-series engines as the injectors are the same type as the DBW S2000s. This is far from bolt on and I plan to work with a few others who have developed similar setups. Will require fuel system changes as well as stand alone ECU, as well as some other details. Should be a very fun project!
I mentioned to Toda that I will using this on an AP2 S2000. In Japan all AP2 S2000s are DBW models, so they provided the kit with a fuel rail that will work with the DBW fuel injector type, which apparently is the same as is used on K20 engines. Hence the "K" on the fuel rail. This will make for some interesting fuel injector options.
Again ITBs aren't really a plug and play bolt on affair. Toda's kit makes it about as close to that as possible, but with the territory also comes the need for stand alone ecu, some fuel system and vacuum changes, among other things. Luckily I am working with someone who has a lot of experience that knows much more about all of this than I do, so I should be able to avoid a lot of headaches. And of course a good tuner is paramount.
The Toda dry carbon surge tank is an incredibly nice pre-preg carbon airbox. Just like the dry carbon trumpets, they are clearly made with proper metal molds and everything fits together perfectly. The camlock latches on the box are simple and effective and seal the box up nicely.
I got the kit with the 88mm dry carbon trumpets, but I also plan on testing with the 66mm trumpets as they will likely work best with the carbon airbox. I also got the ISCV kit Toda offers which will help maintain a proper idle when more electrical lid or load from AC is put on the engine. I will definitely post up all the details as profess is made.
As you can see the 88mm trumpets do take up a good amount of space in the airbox, which is why Toda recommended 66mm trumpets when using the airbox. Having spoken to others about it that have been able to test, the difference is fairly negligible and mostly comes down to the ECU tune, so will be interesting to test. It is simple to remove the airbox and swap out the trumpets so should be fairly easy to test different options. Very much looking forward to getting started and testing everything out!
