The B20VTEC discussion thread

[tinkerbell]

are not all LMA's a 'spring' type?

[Cooker]

My b16a has the enclosed style one (dunno if there is spring inside, think it's a damper with oil in it). The type r or spring style is obvious cos you can see the spring cos that's all it is.
I have the new style at home to change over soon. My lma's so rattly below vtec lol.

[tinkerbell]

yeah, they cased ones have spring inside.

B16A/B18C = old cased style , S2000 = "new" spring style

i guess it is much cheaper to make the spring one, rather than the cased one?

[Lerlo]

how often have you had an LMA fail?

Well, its just for peace of mind, and its not very expensive, thats what im saying.

Speaking of the old type, it seems to be designed as hydrualic, but there is no oil feed into the thing, so it still just acts like a spring..

[tinkerbell]

well, $128 is *kinda expensive* to replace things that in most cases will not be broken?

sure, for example i replace old heater hoses before they blow "for peace of mind", but these are actually not expensive compared to a puddle of coolant on the side of the freeway and a cooked head...

but in the case of an LMA - it can be broken and you'll still drive home/continue racing...


the real question that should be asked is - do the new style offer advantages when used with high-lift cams?

Im just providing information about it, people can decide for themselves.

As for advantages, I do not know, but the new engines are using this style anyway, and it definately looks more robust.

I changed mine because one of my LMAs came apart and instead of forking out $76 for 1 old one, I decided to pay 128 and get 8 new ones.

Also, I was surprised by the price as I read the Americans are paying USD$30 for one...

oh, OK, i must have misunderstood where you said that these parts are worth changing when we are reconditioning our heads...

so what part number did you buy?

was it either of:

14820-PCB-003
or
14820-PCB-305

[logical]

these LMA's.. do they NEED to be changed/reconditioned when I put my head into the shop??? Also does or has anyone in Bris done a B20 setup and if so where did they go to get there block and head work done/places people would recommend?

[tinkerbell]

these LMA's.. do they NEED to be changed/reconditioned when I put my head into the shop???

no - these definitely do NOT need to be changed unless broken.

[logical]

no - these definitely do NOT need to be changed unless broken.

Fab. Now onto the fact that there are 2 types. Mine is a b16a so its the enclosed one. Is there an advantage to have the spring type over the closed type and vice versa?

[tinkerbell]

no...

I bought 305, I think 003 is for h22?
