Im new to the site and i have searched but no luck. I have a 98 prelude wih a jdm h22a swap. I have a problem where taking-off in 1st unless the rpms are up around 2k the whole front end will shutter/shake. Also while accelerating or well when u put your foot back onto the gas(say after coasting) theres a clunk, and then again when you let off. Mods if it matters are: aem cai, custom header, custom catback, resonated test pipe, act stage 3 clutch and 10lb fadanza flywheel, adjustable coilovers, konig illusions Hancook ventus v4(great 4 seasons) and carbon fiber hood, which shakes like a ***** when having the problem. Any help is appreciated thanks in advance.
Mine shakes the same way too if I start at low rpm. I have a torn top motor mount I think that's the problem. Maybe the front one is bad too I haven't checked but I got the top one in the mail so I'll update when I replace it
The header doesnt look special. Just clean welds, no burs. I can get a pic of the outside. But the inside was clean. The guy went with stock design but oversized ports to like 1 5/8ths or something like that and then 2 1/4 collector to go with the custom 2 1/4 exhaust. Power actually went down with 2.5, well low torque did hp went up but overall this design wotked best for torque to hp.

I could definitely be wrong, but from what I've heard on several forums is that stage 2 and stage 3 clutches are known for not-so-smooth takeoffs as far as slipping goes. They just want to grab and go, hence the jerking.
Yea thats what my brother told me. he did a b18c build that made 250whp with just boltons, spoon ecu and stock clutch. The clutch pedal setup is custom though and the pedal can literally only go up and down maybe 2". My clutch grabs way high, i was told that just happens to be where this clutch likes it
Id rather replace it when its out than go boost and have to do another 6 hour clutch job. The flywheel really helps with shifting and revving. Im use to rwd muscle, u throw a pucked clutch in and the only drawback is chirping tires. It is nice clutch, just rev matching (acting like a torque converter)isnt feasable for inner city driving. An 1800 rpm launch and theres no shake at all. Out here in the sticks is great. Its great for getting out of snow ditches too. The extreme positive engagement makes both wheels spin as if its lsd. Also opens options to more hp and less redoing work. How many people can say there na lude does 13.2 1/4m and 5.1 0-60 ? With boltons and tune
