Why? That's the first question. It'll make the motor raspy, make the car higher maintenance, etc. Is your motor built?

Why? Because the car will be at high rpms regularly, faster reving, and rasp. I love rasp. I guess I need to look into the pros and cons more. :hmm: and No, the motor in my car now has 250,000 miles on it and before I go to college next year it's getting a new engine. Like I said, Im still in the idea phase. Right now Im thinking ZHP cammed M54B30 with solid lifters.

Well huh. At high RPMS M54B30s have vibration issues. That'd be the first thing you should look into. ZHP cams don't make power high enough to require solid lifters.

+1. oil pump, oil pump nut, new OE damper or upgraded damper. Though I'm not sure if the jury is out on the long-term nature of the ATI damper. might as well spend money where it counts.

Wait let me try that again. ZHP BEST CAMS EVAR OF ALL TIME MAKE POWER TO 8K NO PROBLEMS.

Which damper are you referring to Mango? This upgrades are interesting..

unless you have a fi cams and are running high HP then solid lifters wont make any difference. on cold start it will make a tapping sound due to valve train growth.

Has anyone on the forum done a m54 solid lifter conversion yet? I am also curious if this conversion will work with the zhp cams, I was thinking redline approx 7400 track auto cross application. Obviously drilled and cotter pinned oil pump shaft/ nut. With a rear subframe complete with m3 diff swap from an m3. The extra revs should work well with the stock m3 diff ratio.

no need to get cute, for similar money you could put a well-running stock engine in there and throw on a supercharger and make way more power in every way than if you decided to go your route. Plus they are bolt on and reversible, and like mentioned earlier, if auto-x is your goal, midrange is what you want and the midrange punch of a supercharged M54 is superb.

I have never seen a forum full of more haters than E46fanatics... Just about any thread that talks more "aggressive" ideas is shunned upon on this site. Not a single response to the OP's original question.

VAC makes a kit http://store.vacmotorsports.com/vac---m5x--s5x-us-solid-lifter-conversion-kit-24-p1034.aspx

Based on what it says there, it requires specific solid lifter camshafts. I would call them to make sure, though, as I can't seem to figure out why (mechanically) a different cam would be needed... Unless they require a smaller/larger base circle.

I would worry more about the oil pump shaft shearing off, even with the nut welded on. I have 330 cams with solid lifters and bmw motorsports oil pump, 12k springs and ti retainers for higher revs. I can turn 9500 and it has on the track, but cams are going to play a huge part here. Also, it is extremely loud at idle and all the way up the range. But it has a distinct sound, it's fun to not have to worry about a money shift anymore lol.

ETA: the vac kit most likely calls for specific cams to make advertised power.

here's the issue: with the VAC kit, you're paying $3700 for parts that will give you 20ish hp, above 5000 RPM. Which is great if you're actively tracking a solidly-built NA car, but is nearly useless on the street unless you're looking for an old-school lopey idle and an uncomfortable ride.

With the right cams you will make way more than 20hp. But it will require other things. Basically the only way to make real power with solid lifters is huge cams which will require you lock down the vanos and run a standalone. Your idle will be somewhere around 1800rpm and you'll have to turn 83-8500 rpm to make that power. Now you're talking forged motor to handle higher revs. Doing that I would expect about 70/80 hp more, by now you're $10k deep and only 280hp, sure you can out rev an M, but not outrun it. Solid lifters sound cool and you can definitely rev the balls out of it, but it's only practical for track only applications.
