Neo Rb25 Vs R34 Rb26

[discopotato03]

Yes but the thing is how are they different , maybe need to look at aftermarket direct replacement pistons to see if the dish volume changed .

A .

Actually this R33/R34 DET business needs its own thread .

I think valve train wise hydraulic cam followers , buckets if you like , are going to be significantly heavier than plain buckets , "solids" , so less valve train innertia for the valve springs to have to control .

Hydraulic buckets are all about no maintenance because they self adjust enough under normal operating conditions .

It is a major and expensive PITA to have to reset clearences on an under bucket shim engine like an RB26 or FJ20 .

Belt off pulleys and cams out to remove the buckets so you can get at the shims .

NEO 25s have solid lifters like the 26.

yeah and the poncam type B's are the only drop in cam that works with a neo without needing to reshim.

Did you measure the valve clearances Simon?

Mine were not at Tomei recommended spec.

[Simon-S14]

yeah i did. they were all at recommended spec.. i guess you got unlucky

you know the clearances are spot on when the top end sounds like a sewing machine on idle
