How much do they run and are they hard to install? I am guessing the GSRs will
pop right out. Larry at ENDYN told me that the CTR cam set can break if you run them without the LM assys. The rocker snaps off the GSR thinner track on its LMassy and causes a bind that will pop. I just realized now what he is talkin about.
Has anyone dealt with this?

Any advice is much appreciated!

Funny thing is the ITR, GSR and SI (99-2k) use the exact same part #.

So Larry is BS'ing you. If you have bad ones, then get them replaced.

You have to remove all the rocker assembly to insert or remove the LMA's.

They run about $30-40/ea.

2001 ITR http://www.acuraautomotiveparts.net/...ER+ARM+%282%29

1995 GSR http://www.acuraautomotiveparts.net/...ER+ARM+%282%29

Check the part numbers.

 

dude you are dead wrong!
gsr honda part # for lma's
14820-p30-000

itr honda part # for lma's
14820-p73-j01

I have the actual honda parts disc that all honda dealerships use to get part # info.

 

Sorry dude, but I'm not. I've bought these before, and I even called the dealer directly.

Guess what.

The last 3 digits of your part number indicate a JDM part. (J01)

I don't know where you got your disk from (ebay maybe?) but call your local dealer, and ask them directly.

OH, almost forgot, that part number 14820-P30-000, well the P30 means it's from a B16A head, not a GSR, which would be a P72 specifically.

It just shows where the part was used first. In this case, it was used in the JDM B16A engines (P30).

Different parts and part numbers, but the same price.

The difference is most likely only in the spring. The outer sleeves are probably machined the same.

The removal/installation is easy once you have the cams out.

my disk is from honda

I have talked to many many other people who build b-series engines for a living, they have tested and seen proven facts that they are different.

the itr lmas are stiffer.

 

Yes-GSR LMA's are different than ITR LMA's. With the cams out, just flip the rocker arms up and the LMA's just slide right out.

 

I just checked your links-Shows the same part #'s for intake valves on GSR's and Type-R's. I don't think I will be buying any parts from these guys....ever.

 

You will have to pull the rocker arms to replace the LMA's.

 

no you dont.

 

B16A,B17A, and B18C use the same LMA
ITR does not.
They are different part #s and they are physically different as well.
Itr LMA has a larger contact tip area than the non itr LMA.
THey are stiffer as well.

 

Yes, and Earl here on h-t verified that the LMA has about .020" more clearance when compressed. That's definitely something to consider when running a radical VTEC lobe. It can be the difference between a broken cam and a bitchin' cam.

thank you for reminding the rest of us how this much overlooked item is a need to for anything larger than B16/17/GSR cams, especially with the rocker arm ratios being different on the various heads, making an assortment of lift at the valves...
