Syko Performance RB25DET Install - When The SR20 Just Isn't Enough

Syko Performance Provides the Ultimate Alternative for Your 240SX

It's a natural progression for most 240 owners-pick up a used chassis, beat the hell out of the KA (unless it craps out on you first), swap in a SR20DET because hey, we could all use more power, and proceed to spend frivolous amounts of money on bolt-ons to make that SR scream. When all is said and done, we'd guesstimate roughly 300 to 350hp would be satisfying, but by that point your car becomes fairly unstreetable as well. Your last alternative forces you to buy a beater Honda and let the Nissan sit in the garage, only to be driven on weekends because quite frankly, it's too damn scary to drive it like it's a normal car. We suggest another alternative for you 240 enthusiasts (and no, this doesn't require you placing any rainbow stickers on the back bumper)-how does RB power sound to you?

Gary Narusawa, along with Marco Vargas at SR20Store, recently kicked things off righteously for his own company, Syko Performance, with the release of a bolt-on swap kit that will allow all S13 and S14 owners to swap in the coveted RB25DET (or RB26DETT for those willing to go the extra mile). The kit's designed for easy RB25 installation mainly because an RB26 does require more modification to fit properly, but both will fit. The kit includes all the mounts and accessories you'll need to make it fit like it came from the factory. Once all is said and done, the jump in power is enough to make you think twice about why you even went SR in the first place (I know I did). As of press time, Syko Performance is only selling a DIY kit for the RB25DET, and during the next few months their RB26DETT package will only be available as a fully installed service by a qualified shop like SR20Store due to the complexities of this swap. Keep in mind, however, that just like the SR20DET swap, an RB25/RB26 engine conversion is not smog-legal and should be used for off-road use only, unless you like paying huge smog fines. Follow along as Gary and Marco give the SR20Store's S13 an engine conversion worthy of the gods.
