Update: RBC Manifold & HardRace Rear Bushings
I made some updates over the weekend in preparation for round 1 of VTEC Club this weekend at Chuckwalla. I bought these HardRace bushings for the rear knuckles from Marcus at HeelToe last summer and just now getting around to installing them. I also had the Eibach/SPC adjustable upper arms i also wanted to swap over. Having the spare knuckles from my silver TSX definitely made the prep work easier as it allowed me time to clean up the knuckles and press in the bushings before starting on the car.
I didn't get a chance to drive the car much after as I went straight into the RBC manifold swap. The rear of my car seems a little unstable when hopping curbs at high speed at the track. I'm hoping these bushings will be the first step to tightening things up back there.
Old knuckle assembly and bushings on the left. HardRace bushings pressed in on the right knuckle.
The RBC manifold swap went fairly smooth but I also did a lot of researching and ordering of parts before jumping into it. Rough Draft's RBC Manifold Details
thread also helped to make sure I had the right throttlebody gasket. Thanks!
The manifold is on and idles great. The power curve has been shifted to the upper RPM range. It does seem to pull a little harder once VTEC enages. There is also a prominent dead spot in the power curve around 4k and then picks up again at 5k once VTEC activates. I need to put some more miles on the car to get a better gauge of what's going on. So far I'm happy with the outcome and know in the end it will make more power once I get my VTC gear on and tune.
I used the Tractuff Water Bypass.
The TSX fuel rail and injectors bolt right up and fit like a glove.
I also had to extend the MAP sensor wire. I unclipped the L-shaped bracket that bolts to the manifold and routed the plug to come out of the top instead of the bottom for a cleaner look. The L-shaped bracket on the TSX harness also bolts up nicely to the RBC manifold.
I finished up late last night so I apologize for the crappy photo. I'll take more pics once I get more miles on the car.
One more photo from months ago when I did a test fit on the silver TSX.
