This might be considered OT, but I'm just curious - do the RLs suffer from the same high rate of hg failures as our G2 Legends?

I thought it would work. I guess the main journals were the same size then. I figured that since the head gaskets were the same then the length of the cam should be too. My main concern was the rocker assy and main bearing journals.

Now throw in a valve job with .5 to 1 mm larger intake valves and you have a 3.5 compatable variation of a Type II head.

It's too bad the engine cradle isn't the same or this would be a bolt up swap.

As for the sensors. All of them should work fine.

The RL and Legend Crank / cam position sensors match perfectly on a wiring diagram, but have different part numbers. This could be for fitment on to the head or the fact that they have different color wires comming out of them, connector etc. If the schematic is correct they should be 100% electrically compatable If the Legend cam crank sensor wont fit the RL head then the Legend connector can be spliced to RL cam crank sensor. I think that sensor bolts to the timing cover back plate if i'm not mistaken, can't really remember. Anyways, if there is a fitment issue then maybe those backing plates are interchangeable.
I have both cam sensors, I'll check and see what the differences are when I have some time. The cam sensor bolts directly to the head, hopefully they both have the same bolt pattern. Off the top of my head I think the connector is the same for either cam sensor, but I'll double check. As far as the heads, even if you didn't use the type 2 valves you could probably have some quality headwork done on the RL heads/valves and throw in some type 2 cams and still get good results (or some Type 2 regrinds would be even better). I had another plan for my car, but this looks so easy I'm tempted to go this route.

I have yet to see a BHG on a C35, so I'd say it's rare vs. the C32.

A quick comment about the BHG since it was mentioned already once in this thread... Does anyone know how common the BHG is in the type I vs type II?

I don't mean to get off topic, just made me think.

I wasn't going to even go as far as swapping cams, I just like the idea of more reliale HGs + the little extra torque.

Thanks for checking that out for the forum...

No problem, always glad to contribute to the community. I checked the cam sensor connectors today, they both use identical plugs so you should be able to use the RL sensor with no problem. Now if we could just get a CAD drawing of the custom mount and produce a few, we'd be set.

I have the RL mount and the Legend mount here but I need DV8 to measure the length of the mont so I can draw it up on AutoCAD. Then I'll see if I can get some milled out. I'll also work on adaptor harnesses. I believe the Type II Intake will fit on the RL heads so that will clear up some compatibility issues.

DV8, if you could just measure the length of the mount or is it the same Length as the Legend mount?

Yeah the Type 2 intake manifold will definitely fit ok, I checked on it. The Legend y-pipe (stock or otherwise) will fit, there is a slight difference in the spacing but it still fits with a little persuasion. We'll be able to use the Legend harness as long as the injectors and coil packs are swapped as well. The mount is the main thing, if someone makes a few I'm sure they could easily sell them. If nothing else, we can each make our own the way Christian did.

Well, if Christian comes up with the measurment for the legnth I will draw it up on CAD and iff I have enough money at that time I will prolly have 10 or 15 made. Then if the market is big enough I will have a lot more made!

If you make them (non ebay sh!t quality) and they fit I would pay $$$ for one.

There is more to it than just the length. There is the angle that the mount slopes from the engine to the chassis as well, I'm, pretty sure it's not a straight across shot, but I can check. You also have to take into consideration that the 93 - 95 Legends have different front mounts all together. Only the 91 - 92s can use the DV8 mount. Also, the motor has to be level (same height as the other mount, sorry best way to describe I guess) or it will go through CV joints like a hooker on condoms because of the extra angle on the inner jounts.

even tho the mounts are different, cant u still use them, they bolt up to the engine in t he same place, u dont need to change mounts when swapping to type 1 to type 2 engines, so wouldn t it mean the difference in the mount is where it conects to the subframe but still mounts to the engine the same spot? so we (93+) ppl could still use are stock front mounts? or is it one of the front mounts that was the one that did not line up?
i think i just answered my own question, could u swap the sub frame from a 91-92 into a 93-95?

Yes you can change the sub frame. But why do all that work? I'm picking up a 95 LS Coupe within the next month. Got it dirt cheap. The body is a mess and the interior is trashed but it runs like a raped date. Then I will have a 91 to fit and adjust the 91-92 mount and a 95 to fit and adjust the 93-95 mount. The mount in question is the front mount on the passengers side of the car under the power steering pump.

DV8, I know it would be a big hassle but is there any way possible that you could remove that mount and make measurements. I will first have to do what you did and make one mount from the 3.2 and 3.5 mounts. Then I will have to do the same for the 93-95. From there I can make all the proper measurements and then modify it to see if I can make the mount even stronger than stock.

the only reason i was talking bout subframe swapping because it didnt sound like there was anyone with the 93-95 wanting to do what it is obivous 4 of us seem to plan to do and i figured who ever made the custom mount would not want to make a totally different one for one person or something

Yes the only way to make the earlier 91 - 92 mount work on your 93 - 95 Legend is to change the subframe. It would be easier to make a mount that would fit the 93 - 95 style mount.

While we are on the subject of mounts, this is a little off topic (my appologies DV8) but what I did on my 93 sedan when I installed my Type II is replace the rear mounts with the ones from a 91 - 2 Legend. They are solid rubber not the origional oil filled hydraullic mounts. They do transmit vibrations a little more at idle, but the car seems to have a firmer shift that I like very much. i did this in hopes of keeping engine/tranny movement to a minimum to preserve the short life of the rear tranny mount (hopefully, but probably won't). It will probably last a while anyways as it's my wife's daily driver and she drives like my 80 year old grandmother.
