i live in ny, yes just about everyone around here that builds cars is looking for the cheapest way to be the fastest and the cheapest way to be the flyest everyone has rotas, on my ny forum theres at least 1 new thread a day about how to save money, or how to junkyard turbo your single cam in your hatch.
theres also a bunch of shops in the long island nyc area that cater to what ever you want,
to everyone that said theres nothing theres
fizz
www.fizzautosports.com/ they'll build you want ever you want, suby, supra, 240. they stock jdm wheels and other hard to find jdm goodies, but you pay for it, way over priced
wings
www.wingsperformance.com they are mr.240 of ny they have a large 240 following. id say they get most if not all of the nissan business around. they also stock front end conversions, they also stock some jdm parts, and can get you what ever you want from japan. also overpriced
nrg tech
www.nrgtechracing.com mostly honda stuff, they have a dyno and a good tuner, and will build you whatever you want as long as you want it fast. good people good prices
no limit motorsport nolimitmotorsport.com they are an online mail order based sulffok long island. they stock whats needed and can get just about what ever you want.
the only places to race that i know of are englishtown nj, they do parking lot drift events some auto cross, and drag racing, then theres atco nj which is a drag strip to my knowledge, and island dragway nj also a drag strip.
all im saying is i dont think theres much out here in the way of tracks that arent drag strips or circle tracks.
but if you want to come out here, DO IT, theres always money to be made.
ill buy parts of no one else does. but theres defiantly a growing market out here, hell greddy opend up a warehouse in nj.
if you build it they will come.
good luck to you
