Sorry about the lack of updates lately, I'm still out of the country and should be back in a couple weeks for actual "hands on" stuff like installing and documenting the parts I've bought. My most recent purchase is from a company called Prospeed, they specialize in ECU tuning as well as a few other products (hi-flow cats, exhaust). One of the hottest new products right now are RDX injectors along with their custom ECU tune (required for use). Here's some basic info on the kit quoted from their vendor ad.
"After months of testing and hours of dyno tuning we are proud to introduce one of the best bang for the buck mod for your naturally aspirated NSX. The NSX from the factory comes with 240cc injectors... quite small for the displacement of the NSX. As with most Honda injectors the NSX injectors from the factory run high duty cycles stock and in this case if you do any exhaust modifications such as headers, test pipe/high flow cats and exhaust it will cause leaner conditions. The best way to resolve that issue is to either raise the fuel pressure or install larger injectors and that's where the RDX injector comes in.
The RDX injector is a popular mod in the B/H/K community for people looking for a reliable and affordable injectors for their turbo or high hp N/A build. The RDX 410cc injector is a modern injector with an excellent spray pattern which helps with the combustion process. The injector also offers excellent idle characteristics thanks to an increase in control of the injector.
Dropping in larger injectors is only recommended if you have an aftermarket engine management system or our new Prospeed RDX Spec program. Your car will not idle or start if you install larger injectors without adjusting for the size with your engine management. The Prospeed RDX Spec program is custom tailored for the RDX 410cc injector. We have spent hours on the dyno to fine tune it and now we have a perfect alternative to a AEM FIC or AEM EMS. The RDX Spec program idles like the factory injectors and produces some serious hp and torque gains.
It's time to get rid of your 20+ year old injectors and install an easy plug and play "bolt on" mod for your NSX. Next to headers and exhaust nothing comes close in terms of bang for the buck in the performance category for N/A NSX owners."These guys definitely know what they're doing and their tunes are second to non. They are NSX specific and the different tunes are even broken down to what type of mods you have (intake/exhaust, intake/headers/exhaust, intake/headers/test pipes/exhaust etc etc). I ordered my kit last week and had the wife and a buddy go to my storage and remove the ECU to be shipped out and chipped, that way there is no down time when I return. I can plug in the ECU and replace the injectors and its good to go. My vtec will be lowered to 5600rpm and rev limiter raised to 8200prm as well.
Everything is of course dyno proven. The car that Prospeed did their testing on had a mid range torque gain of 37wtq and 16whp up top! All the while running a much safer air/fuel ratio.
Another customer with 175k miles on the clock made 20wtq mid range and 10whp up top. My car only has about 55k so I'm hoping to be on the higher end of power gains.
All in all stay tuned in a couple weeks when I get back, my to-do list includes: Installing this kit, installing hi-flow cats, painting/installing my carbon fiber rear valance. So expect many pictures (and maybe some sound clips
)
