I have a CL9 with k24a3 (same as k24a2).

I mounted 3 aftermarket engine mounts, front and rear from Hasport with 70A, and rightside mount from Innovative with 75A.

Stock oil pump:
My car was very nice to drive, great control over the front tires with no wheelhoop and the engine wasnt moving around anymore under WOT or when shifting gears. Vibrations? Haha no, what do you mean?!? Well I could feel a liiiittle vibs in my seat. I had to concentrate to feel it. Life was good, sunshine everyday!
A side note: I have access to a dyno, so I have tuned my car many times, to the dyno we have this wireless Logitech keyboard, and on every run I put it on top of the dash, in the middle of the car, just below the windscreen. It stays put there, no moving, or rattling or nothing.


Changed oilpump to k20a2:
-well, limited to stock rods I have set the revlimit to 7600rpm. Gained 6hp@6nm with this pump up top. First run I did I got scared, I heard and felt strange things, like now something is braking, but the second after I realisted that I had a Logitech keyboard jumping up and down on my dash. Every vibration made it jump up and hit the glass in the windscreen. So I put the keyboard in the soft place of the passanger seat. But the noises were everywere, rattles, sounds, vibrations. It feels like my car is braking apart.
I still drive with this setup, I hate my car. My wife doesnt drive it anymore. My youngest boy now loves it, he have found out a spot in the rear seat where you can, with the right technic, if you open your mouth and shape the rightsized hole with your lips, a sound will appear. Almost like when you blow air down in a empty beerbottle.


K20's doesnt have this kind of problems with stiffer mounts.
So in my world, a k24 should only run without the balance schafts in a REAL race car. That 6horsepowers I would gladly find somewhere else. They werent cheap either. Took me 8hours and cost me almost $400.

Thanks for sharing your experience! Out of curiosity, how would you describe the difference in vibrations between a K20 with stiff mounts and your K24 (with stock oil pump) with stiff mounts?



:up:

My butt says that k24 with stock oilpump has like no vibrations at all. Ive had 2 CL9 cars with k24, my first had turbo and I had the stiffer mounts (race) from vibratec/Hond-R. My second that I still own has hasport and innovative mounts with 70-75a and it feelt nice and smooth with stock oilpump.
Ive own many cars with k20a2's in.(EP3s, DC5's, EG's, one CRX...) And been driven ALOT of cars (proberbly almost 100 different cars with k20). I feel that k20 vibrats more!

•Smooth: k24 with stock oilpump
•drivable: k20 with 60a is okey
•my worst nightmare, a high comp (12,5:1 or higher) k24 with k20a2-oilpump!:blur:
