If you didn’t know already, some mad Kiwis in New Zealand have managed to not only stuff an NSX engine in an Integra Type R chassis, but they’ve got it running and moving under its own power. I’ve been following this build since the beginning of this year and it looks like the boy’s from Speed Science are in no rush to get this project done, as it should be. Earlier this weekend, Speed Factory tuning and fabrication dropped a video of this unique ITR idling away and it’s got us absolutely stoked to see the finished product. Check out that video below!
In addition, we’ve posted a couple of other videos showcasing this ITR moving under its own power as well.
Underneath the rear decklid of this Integra is a C30A engine and rear running gear from Acura’s everyday supercar, the NSX. Instead of turning the engine 90 degrees and running a driveshaft to the rear or simply swapping out the B18C5 and cutting a hole in the hood, Speed Science have kept the original drivetrain configuration of the NSX as it was meant to be from the factory.
According to SS in an earlier post, they were “….Just keeping the same configuration as the NSX. Had the whole rear end so made sense.”
Although the C30A V6 is over 20 years old, it puts out some decent power once VTEC kicks in at 4,800 RPM. At the crank, this NSX V6 makes 270 HP and 210 lb-ft. Pair that engine to a chassis that comes in a hair over 2,000 pounds and you have a recipe for one serious track Integra Type R. And since it’s now mid-engine configuration, you can properly point the front wheels and give it the beans with the power to the rear wheels around a corner.
Keen eyes will notice on this particular Integra the addition of a NACA duct on the side rear window that routes air to the C30A’s intake manifold. On the NSX, side ducts on either side both provide cooling to the engine compartment, it’s oil cooler and most importantly, air to the engine. With no side ducting on the Integra Type R, a ducting solution was in order.
Stuffing engines in an MR configuration in FWD chassis aren’t something new. Afterall, Honda managed to do it themselves in the earlier stages of the NSX’s development by putting a mid-mounted engine in a CRX and changing how the rear suspension reacted to the changes.
I’m just glad to see this project moving along. Updates on the progress on this build will be posted as they come in. In the meantime, enjoy some of those aforementioned videos promised.
