Here it is finally... our J35 swap in an S2000. I know it's really really ugly, but I couldn't wait to post it up online. To my knowledge, we're the first ones with a running J block in the S2000.
J35A4 from a Honda Pilot
AP2 transmission
Running the OEM ECU
Built at Intercrew Auto Salon in Garland, TX (NE Dallas area)
A few things aren't hooked up yet, but the car starts on its own, has all the plumbing connected (minus intake and exhaust), and it pulls like a monster. First startup on the dyno once the fuel system was in place yielded 269hp/286lbft at the wheels, and that was stopping at 5k rpm. Over 220lbft was available right at 2000rpm! The goal is to build up for all motor and turbo, and shoot for 9000rpm to keep us rev-crazy S2000 people happy.
Enjoy, and please ignore the ugly- especially the floppy trunk lid. It'll get cleaned up- I promise.
So Khiem, here's your power option. I know I've tried to beat you over the head with it. 
There is the possibility of making this California legal since the stock ECU does work.

I dunno if this is his power option... Something tells me the weight issue wouldn't appeal. What sort of modifications have you made to produce the power you are currently? Congrats on an impressive swap! |

Thanks!
There's less than a 100 pound difference compared to the F20C/F22C, and it's all behind the front axle line. The car only weighs 2400 pounds as it sits right now, so it's not going to be too far from stock. There are absolutely NO modifications to make the power it put down, other than maybe feeding it 93 octane. Other than the mods required to mount the engine longitudinally and mate it to the S2000 transmission, nothing has been changed. Stock internals, stock ECU. Given that it would put down over 300whp revving out to redline, I think it would be a good option- especially since it would be just as reliable as all the zillions of J blocks swimming around the country in street trim.
Khiem's known about this swap since we started on it (almost two years now)- his main issues with it would be downtime on the car and being street legal in California. I don't know all the rules in Cali, but I'm hoping that since we're trying to put all the J block hardware into place and make it run with the J ECU that this setup could pass a smog referee check- not 100% sure though. |

I love that you're showing the J-series some love, BUT I LOVE driving and hearing a solid F20/22c scream to 8.5-9k. So If you can make the J reach those levels of musical/oxygen sucking sweetness, I'm all ears! |

The rod ratio on the J35 is 1.70 and it only has a stroke of 93mm, so while it's not as nice and undersquare like the F20C, it's still better than a lot of the B series engines that commonly rev out to 9k. Considering the torque the engine is putting out now, assuming I can maintain 300lbft of wheel torque up through the rev range, 8754rpm is the magic number where 500whp would show up on the dyno. Even 260lbft @ 8000rpm would come up right at 400whp. I think 400whp would be pretty easy- but 500whp is the target. That kind of power would sound pretty sweet at 9000rpm- and the bonus is that it would maintain the character and high-revving feel of the S2000, just with a hell of a lot more push! |

I'll build one with cylinder deactivation for ya. Oh, gotta look into that 6th gear. |

As far as CA smog laws, it wouldn't fly. You can't transplant an SUV/Truck engine into a sedan/coupe. I think B-series guys ran into the same thing trying to use the B20(I think?) from the CRV.
Outside of that, this sounds like an awesome project. |

Oh, I know that THIS setup won't pass in CA. I'm not worried about that. The Pilot and Ridgeline are only two sources for the J35... Honda put them in so many cars, you can pull from an Accord, TL, RL, Odyssey- whatever you wanted that wasn't a truck and still build it the same way. |

They'd have to ask for the last two digits on the engine code because a J35 can be found in the RL and TL as well. |

Oh, of course! Pretty sure they check all the engine code digits in Cali. |

Hood and bumper are on, hoping to head to touchup and paint in a few days. Everything fits like stock! Nobody will ever know what's under the hood...   |

I know you mentioned that the engine is all behind the front axle line... so what does that do for the weight distribution for the car as compared to stock? |

I'm hoping you guys give the exhaust note a touch of the exotic when we see the next video! |

Weight distribution, not quite sure yet since it hasn't been on the scales as a complete car, but it should be pretty close to stock. I'm going to guess maybe a shift to 52/48 F/R, but we'll move a few things around to get it just right.
I hope so too on the exhaust note! Open manifolds don't always sound too sexy. I'm headed to the shop right now- we'll see where things are. |

Car will be at Wekfest today at the Fort Worth Convention Center. Come out if you're in the Dallas/Fort Worth area!

Looks good!! How'd the show go?
Man, I forget how good the front fenders of the s2k look... too bad those sexy flares arent' on the rear fenders too.
Curious... the AP2 transmission just bolts onto the J35? does that mean a RWD accord/TL/TSX is theoretically possible? I imagine ppl would drool over a RWD TSX Sport Wagon. |

Didn't make it to Wekfest... radiator decided to let go on the way to the convention center. Looks like the radiator was bad from the previous engine's turbocharger taking a dump a few months prior. We'll get out to another event soon. "Just bolts" is far from reality. A RWD Accord/TL/TSX is definitely possible, but you'd have to do all the same fabrication and more compared to what we did here. Turn the engine 90 degrees, mate it to a RWD transmission, then cut a transmission tunnel, mount a driveshaft and rear end, mount rear hubs to the suspension. It would be easier to do it to one of the SH-AWD TL/RLs (I think the TL was available that way) and just disable the FWD system. Not much point there. So... a few more pics and another video. Yeah, that makes it better.   Video here, up to 720p if you want semi-HD goodness. http://www.youtube.com/watch?v=RBVuwA7b1LM |
