A fellow redditor reminded me that this thread has been lonnnng overdue for an update. It turned out to be a busy end to the season, and my wife and I welcomed our first child in February. Needless to say, spring has sprung here in NY, and that means, it's S2000 time again!!!!
When I left the thread last year, I had a few things to button up prior to my tune, notably the fuel upgrades and the auxiliary box required to run a fuel content sensor with my Haltech ECU.
I don't have any pics from the fuel pump install, but that was very straight forward using a single Walbro 450 pump and SOS wiring kit.
Pretty pretty! This Radium stuff is top notch:
Rail/Gauge/injectors installed:
With the pump/rail/injectors all done, it was time to incorporate the Fuel content sensor to the mix.
I ended up piecing together my own version of the SOS kit (local buddy has the hookup on GM parts) to save a few bucks. At the end of the day, despite saving some money on the sensor and fittings, it would have been easier to just buy the kit from them in full, as it really makes the install a breeze. So shameless plug to SOS for that kit.
All mounted up nice nice under the car:
Couple bonus pics from my boost actuated cutout. The piece is the 3" unit from Loudvalves, and has performed well thus far. The car is quiet around town, and is more or less open downpipe from 3-4psi on. The valve starts to creep open right when the turbo starts spooling, exactly what I was after:
After getting all of the above taken care of, my last order of business was to install the expansion box for my Haltech, and get it all wired up. I don't have any pictures of that step as it was admittedly quite boring, but everything is installed and working well!
With everything seemingly all set, It was time to load the car up to head down to PA for some tuning action.
We started with the pump gas map, and finished that map with somewhere in the 460whp range @14psi. Could have pushed it a bit more on the 93, but there was really no reason to as the car will see E85 most of the time, and the pump map is more of a backup/there for the flex tune.
We drained the tank, filled with some pump E85 + a few gallons of X98 for good measure. Prior to the first pull on the corn, Jeff said "watch this make 100whp more at the same boost level, THAT'S how good of a fuel E85 is"
Sure enough, he was right. After a few fueling tweaks to accommodate the E85, we spun the dyno up again and boom, the car made 550whp @ 14psi :lol:
We started to run into some fuel pressure issues and ended up finding that my AEM FPR had too small of an orifice installed in it. The FPR was the only part throughout this "re-do" build that I bought second hand. For whatever reason, I also bought a brand new one as a spare (2 days beforehand) to bring along with me to my appointment, just in case and shit am I glad I did.
We swapped the FPR out on the dyno, and got back to business:
Unfortuntately, as we started bringing the boost up more, the car started acting up/sounding a bit off during the pulls.....my clutch had had enough
We finished the day with the car making 630whp/425wtq (you can see where the clutch let go in the graph)
Despite running into a few issues during my appointment, I can't say enough about how happy I was with how the car performed overall, and as always, how professional and on top of his shit Jeff really is.
Jeff is incredibly smart, experienced and articulate, can't recommend him enough.
