valve question, please help

[opensource]

i will know tomorrow if we need them or not, but i need to know the valve specs (sizes, type, etc) that are used in the rb25det. is there US a equivalent and if not where can i get a cheap set in the US. thanks.

I do not think there are a US equivalent of the RB valve, but most High performance valve companies can make them..Why do you need them?????

This should help. AFAIK there is no us equivalent. You can probably call up ferrea and ask them to make a custom set..

Right timing pulley broke on my buddies RB. Happend at low rpm, but still fearing the valves are bent.

****idy **** ****, zero compression. it needs a head or a set of valves.

First find out why the pulley broke, it might happen again if something is not right. Do a leak down test to see if the valves are bent. If they are you might/probley broke some valve guides also. Make sure the head is done by a very good shop so all problems are fixed......

we used to short of a bolt for the pully. when we re-assembled it the first time, the wrong bolt got used. it was to short. that and i think the timing belt was to tight. i installed the correct bolt this time, grade 8 too. with all the spark plugs installed and you try to start it it just spins so free, there is no compression at all in the motor.
