We specialize in Honda/Acura builds, mostly B-series and K-series, and we're getting into the newer Hondas now. We do LS stuff too: Gen 2, Gen 3 and Gen 4. We build custom turbo kits, tailored to the customer's needs and build, and we do a lot of consulting for people's builds as well.

A lot of our fabrication is in-house: intakes, catch cans, brackets, downpipes and more. We dyno tune, and we tune a lot of Holley EFI, Honda, Haltech and other standalone ECUs. We don't mind general maintenance either, especially on the cars we build and take care of. We try to be a one-stop shop for just about everything. The only thing we don't do is machining, and we have a local shop for that.
