I have a b16a sirII in a 91 crx si. I am curious if the guys making big power use any kind of a front motor mount.

I am aware there are a few makers of traction bars that offer a front mount upgrade. Although most use the holes in the trans case. Well I have a hydro trans that does not have those holes. So the mounts at the trans are seemingly out of the question.

Also, I really dont like the ones that mount at the ac bracket holes because that sets the mount so far to the side its pretty much useless in my opinion. I think it should be more close to the midddle of the eng. and trans. If thats not the case let me know, and I can put one there very easy.

So would a front motor mount of some kind be critical on a big power crx with slicks> Or are most guys getting along fine without. Thanks for the help.

 

get solid mounts and you wont have to worry about a front mount.

 

I have hasport race mounts which are as close to solid as Im going to go.

I have no problems or engine movement under load but have heard stories of cracked or broken rear crossmembers

 

I've cracked the rear crossmember on my CRX before. Welded it back up and hopefully it holds. No front mount yet, but if it goes again I'll definitely be adding one.

 

Would like some more opinions please

 

i bent the rear cross member and didnt know it tell it broke the rack off at the track @ only 450 whp and drag radials

 

O damn

 

So what did you do to correct the situation?

 

I can run a mount to where the ac bracket would mount. I just dont know if this is a good spot to take some of the load off the rear mount or a waste of time. Opinions?

 

those are called torque mounts and they arent any where near as effective as a real motor mount.

 

More mounts the better... EF's are the worst. I ripped the trans mount off of the frame rail on my CRX N/A years ago.

 

you need a front mount in a crx, if you run it on slicks or radials long enough you will crack the rear crossmemeber and or tear the tranny mount out on the unibody... I had a 1/4" inch steel front mount. I had a tab welded on my traction bar, and then it went thru the lower trans bolt whole. In my new car I am going to make a lower motor plate. Basicaly go between the front traction bar,and the rear crossmember. It will act like a clutch cover but bolt to both crossmembers....

 

AHH hah... Thats exactly what I was thinking of doing. Going to the lower trans bolt hole.

I will put up some pictures later. But the bar I have is a totally redesigned by me etd bar. Every weld rewelded on both sides with strong thick brackets welded on, to bolt up not only to the tow bolt holes but both factory crossmember holes on both sides. I stiffened the crap out of the thing. It came with the bracket and the bar to go to the ac compressor area. So I could easily bolt it up, I just dont like the placement to much. Maybe I should weld something up to go to the lower bellhousing bolt instead?


The pictures below are just for reference. The pic to the left is where the front mount I have is supposed to go. It just seems too far to the drivers side to do any good. But maybe im wrong, the rear crossmember mount is pretty far to the pass. side. so maybe it will offset it. But it is right in between where the 2 axles enter the diff as it should be.

The pic to the right is explicit speed but I dont have a cable trans so it wont bolt up

 

with my old crx the traction bars came very close to the trans. I had a mount that worked with hydro or cable transmisions. it went to 1 trans bolt whole, the one that went in by the oil pan in the front of the motor. It was one of the shorter 17mm head bolts. The front mount would rest against the traction bar, since the old full-race design had 2 bars instead of the curent single bar design. Basicaly the mount prevented any torqueing up...

 

I can't post photo's from work, but they are on here somewhere. For the Civic I had solid plates made for the A/C bracket to the traction bar mounting point. It's simple, it's just a 1/4" steel plate with one hole for the A/C stud and 3 holes in the other end that mated to the frame. Had the same made for the tranny side except it was a L bracket shape.

May be something like that could work.

 

I already have a etd style mount that can go to the ac bracket mounting point. So I could very easily install it.

What I need to figure out is if I should use it? or make my own mount closer to the center of the engine and trans where I think it should be to correctly control engine movement.

Ahh.... I just realized that you used one on each side. one on the trans and one on the motor. Hmmmm. thats an interesting idea. But Im still curious if just the a/c location would help

Looking forward to seeing those pictures

 

What are all the 9 and 10 second rex's using for a front mount if anything???

Im in kansas and dont have many running around to look at.

 

I was hoping a few more people would chime in. Maybe I shoulda made the thread title a little more appealing.

 

I think a front mount on any car is essential. (Keep in mind that littlebluecrx up there had I think, the fastest SFWD style CRX ever)

 

YOU GOT A B16 YOU NOT BREAKING ANYTHING.... J/K

 

Fastest until I'm done with my littleblackcrx! J/K very nice car

I guess the question I am wanting answers to is.... Will just the mount from the trac bar to the a/c bracket holes be adequate????

 

I could break a crow bar in a sandpile

 

You are why i got this made cause it freaked me the F**K out after breaking my rear cross member. I drive mine on the street and that can not happen.


Plus with this new one i lost 2 pounds over the old one

 

Wow that is great work right there.Should have made a few.

 

im using hasport solid mounts,welded my frame rail brackets and the seams on my crossmember.I didn't want to rely on the spot welds.I eventually want to have a crossmember made just like brad. Any info on who made it and price?
