Hydraulic vs. Solid Lifters

[daty240z]

I am rebuilding a P90A head from an L28 turbo and was confused when I came across the hydraulic lifters. I have not seen these before on a cylinder head so I am wondering what people think about them. I've seen videos of people who do conversions to solid lifters using time-serts but am not yet sure if I want to invest in this. Is it worth it? The hydraulic lifters I currently have seem pretty solid with no play in the pivot. It would be great to hear any thoughts or experiences regarding these hydraulic lifters. Thanks.

There's a procedure for testing them.  They're called pivots.  I've only read of a few problems with them, they can wear out.  You can probably replace them without removing the head, engine in the car, if you have to.

I am running a P90A on my turbo car and so far (4 or 5K miles) no problems at all. First thing you will notice how quiet the engine is. The only limitation I know of (other than you can't get new ones) is you can't run a really big cam (460 lift max I think).

I am looking for another cam for my spare P90A if you have one you want to sell.

What's the number and grind stamp you're looking for?

Hello Captain, long time no chat. I followed your 280 throttle body rebuild and you helped me rebuild mine with new bushings to fix the sticky throttle.

I will check tomorrow and get back with you.

Here are the numbers off of my bad P90A cam.

I have a bunch of turbo parts around here that I'm not going to use. I'll look to see if I have a cam. And even if I do, I don't remember if it's a regrind or stock. I'll check.

Glad to help with the throttle body!      I finally gave up on the S30 throttle body completely and switched over to one from a Sentra.

Daty240, sorry for hijacking your post.

I noticed when people convert to solid lifters they use the same cam, according to this chart there is a difference between the 2 and I would think one can't replace the other, I was told the offset is the main difference between the two, not sure what that really means
