The main reason they probably won't release FP for the 9th gen is that all the same people who said they would buy one for the 8th gen never did. Lots of talkers no do-ers. Also this huge list of 66 people? I doubt anyone seriously buys a turbo or sc kit for their cars. It's simply not worth the money. For the $5-6k hit to install and make maybe 180hp? You could spend the 5k and upgrade to an si, have the power, suspension, better brakes, and 6-speed for the same cost. Also you would certainly have a better platform to upgrade from there. Very few parts have been made to address the main shortcomings of the r18 engine in terms of limiting its power. People dropping $5000 on a turbo kit will also have to get several custom parts made if you want to make good power and not waste your time making barely stock Si power.
Not hating, since I drive an auto LX, just realized the cost/performance barrier was not worth it in the least.
The base "kit" from full race is $4464.34
Now you still need:
Flashpro : $700-ish
Exhaust, injectors, upgraded fuel pump, intake, hondata 4bar map sensor, and some other supporting mods.
Say you get all the extras for $1000, which would be insanely cheap, you're still looking at $4500 turbo kit, $700 flash pro, $1000+ of extras. Over $6000 and you still need a tune.
Tell me you can't trade your car +$6000 and not get an Si? Also most of the 8th gen guys who bought turbo kits and did not go with custom cams or intake manifolds were getting about 180hp. Less than a stock Si. Yes you can get into the 200hp+ range but that requires some serious custom parts and definite drive line and valve work at that point.
All that said, the list of r18 flashpro guys will not return sales. Bolts on and FP/tune will not do for the r18 what it does for the Si. I wish it did cause then I would have had a whole lot more fun with my car.
