We have another major blog post and Forum Build Thread update for our J37 Honda V6 powered 2013 FRS, which we call Agent 86. This only a week after a big update on the build. In this installment we pick back up where we left off before – finishing the engine swap and getting the V6 fired up and running.
In addition to a lot of plumbing, wiring, trouble shooting, tuning and more engine related updates covered in this triple forum post we also added a 4-point roll bar from Walker Pro Motorsport. That makes this SCCA Max4 prepped car legal for “Level 2 Safety”, which allows us to remove the back seat and some other interior bits. It also gives us a great place to hand harnesses from.
More safety upgrades covered in this update include a full Lifeline fire suppression system, and we explain why and where we have nozzles, fire pulls, and more. In the same shipment we also received a new Lifeline 6-point harness, which we installed for the driver. There was a Lifeline tow strap added to the rear as well.
After a bit of struggle the engine was finally running on all 6 cylinders, and we took a brief test drive. The car was then transported to a chassis dyno and Mike from Sakura Garage Tuning remote tuned the car with help from George at Link ECU. Making 302 whp in our first outing was a nice goal, and we also found that the VTEC switching wasn’t functional and we ran out of injector flow at 6500 rpm. More things to tweak there should unleash more power soon.
That temporary 6500 rpm redline and “only” 302 whp was enough to drop 4 seconds off this car’s previous best, which was also on 315mm tires and with coilovers. This was done in one shake-down session, where some little teething pains were discovered that kept us from pushing harder. We brought the car back to the shop where new injectors awaited and began working on the aero. You can read more of this 3-part Forum update starting here. Thanks for reading!
