Is there a difference in the 92-96 h22 lost motion assembly to the the 97-01 I heard there is but I haven't had a chance to crack open a 97-01 head yet to confirm.....
thanks

Yes, there is a difference. The 92-96 is similar, if not the same, as the Integra LMA, while the 97-01 is the open spring style. I'd have to check part numbers to say the earlier preludes are the same as the integras, but I know they are more expensive, and not the ones people use to upgrade.

 

I was under the impression the 97-01 heads used the same LMA as the type r just wondering if that was true

 

Completely different... also the head on the 97+ Preludes is machined different in this area. If you use the 97+ LMAs in an earlier head, you will need to use a .040" shim.

 

so all and all the 97+ heads are better

Yes there is a differnce. But they are the same for vtec 93-98 99-01 yes 99-01, No I do not know why 97 and 98 have the earlier desing they just do. The 99-01 have diffent part #'s and a totally differnt design hope this helps

 

Ah, that's right. I couldn't remember what the deal was. I thought that there was some wierdness like that, but I forgot the year split.

 

well the head I have is stamped 99 so technically it is a 2000 head so I am good to go

 

It's easy to see the difference:




If you have the valve cover off, just peek under the rockers and take a look, the Prelude LMA is a bare spring, the Integra has a housing around it.

 

bringing this back from the dead for confirmation,
on a b series head you need to use the 92-96 H22 LMA's which are part number 14820-p73-j01 correct?

 

o come on...

nope you need the newer style h22 lma's i beleive PCB's dont forget the .040 hardened washers
or just plain ole ITR or GSR lma, but theyre more expensive</TD></TR></TABLE>
really? i thought it was the p73's bc they look almost identical to b series lma's?
Thanks for the heads up man

 

they look nice..... but, can you run those and some skunk2 pro1 cams?

 

call me a noob or w/e but what does an lma actually do? i have heard people swapping them out for other lma's but i dont know why? is there ne advantages?

actually you're right, either run p73's(p73's are not prelude lma's they are actually typeR lma's) or run pcb's with shims... someone correct me if im wrong

in lamest terms they prevent the mid vtec rocker from flopping around...

advantages are pre-obd 1 are prone to failure (binding and rocker arm pad issue's) also if you start getting a rondom tick from your vtec head a worn lma is likely the cause, instead of spending $250+ on gsr or itr lma's people use h22 lma with shims (theyre slightly shorter in length) ..

example: i personally run itr lma (same as gsr just different part no) since my head is a 90 B16a head i upgraded for insurance...also because they were already ticking pretty loud..

i actually just installed some h22 lma's with shims in my cousins lsv..waaay cheaper route than the alternative..

ahhhh that makes sense. i always thought that the ticking in my motor was because of the large cams i was running and that i needed a valve adjustment when in reality it is my lma's. lol looks like ill be buying some itr lma's now lol

 

does ne one have a link to where i can buy the itr lma's????

 

i would still like some sort of proof or something that they wont bind or eat at the lma walls. any post of prelude people running big cams with these?

thanks for the pic , looks like those are the part nuber for my f20b (pcb)

PM omni-man

 

for anyone that's interested i pm'd "drdisco69" to verify the part number on the H22 LMA's you need for a b-series and he said that it is "14820-PCB-003".
And here's a link to where you can get them at $7.17 a piece http://www.hondaautomotivepart...r+---
