Has anybody tried solid lifters on 4G63 engines? If so, what kind of results did you have? What cams? How high could you rev the engine? Thanks!

Haven't tried them but you'll be adjusting you valvetrain all the time like on those old VW's if you do it. Since you track I'm not sure if that matters to you though.

That's not a concern if they help me get 500 more revs out of the engine. BLE offers a set. I can't believe nobody on this list has tried them.

There was a fair amount of discussion on this on the NABR forums awhile back. www.teamnabr.com . Wasn't found to be all that helpful if I recall the scuttlebutt correctly. Never looked into it myself. If you do search around on the DSM boards look in the time range from '99-'02. The DSM HLA's are good to around 11,000 rpm (I believe the Evo ones are the same). You looking to go past that? :shock:

Hell no, 9K is good enough for me.

I think you should try asking John Sheperd about them. I think I read a thread where someone mentioned he tried them before.

I'm not looking to fix a problem that does not exist. If the stock HLA's are good enough to rev to 11,000, I don't need to change them.

Do tell about the oiling problems. Just curious

He killed his rod bearing months back at thunderhill and is now using an accusump.

I would be really weary of the oil pump keeping up with 9,000 rpm on the track but that's just me.

Honda's do it no problem. :)

That was my concern too. *That's why I was looking into solid lifters. *But if people have run these engines with hydrolic lifters at 11,000 rpm, does that not prove that the oil pump can handle that many revs? *

Yea, in a straight line, not all leaned over at the track pulling crazy G's.

Good point! This is no different than the rod bearing problem.

Yo Navid,

Forget the lifters and get the Cosworth cylinder head, that is if the stock lifters can give more revs

LOL, anything for you buddy old pal.* Let's see the check's in the mail, you'll get it tomorrow, just waitin' on the wire transfer, AAHHH Nope no way good luck.* First I'd have to get mine.* By the way what do you think of the B&B exhaust.* Not all of us can do a full wrap on out car and put 385's on the street and still have a job. :-)

That IS my job dude! :)

B&B as in Billy Boat? I haven't heard anything about their Evo exhaust but in general, I think 3" piping is a bit much. Unless of course you are giving up road racing and getting into drag racing. :)

Drag racing never! I like my tranny intact.

Why do you think 3" is a bit much? Is this from the point of the power level you want/need/have is served well by a smaller exhaust?

It's not a problem if you are going after peak power numbers, but you need some back pressure to not loose your low-end power. Having low-end grunt serves me a lot more than having a couple of more horses at the top-end.

Best of both worlds, 2.75" DP to 3" catback. ;) I'm no engineer but I heard that farther downstream is when you want the larger tubing anyway since the exhaust air cools off more by then and becomes more dense.

Wouldn't the opposite be true since denser air requires less room? I'm looking at my Hayward and Scott turboback and it seems like it's wider on the downpipe (2.9") than downstream (2.6" around the test pipe.)

But slower air right? Like I said, I am no engineer so I could be wrong. ;)

That may be true. I just don't have enough data to verify or reject this theory.

Phuck those douchbags Alabama hicks! NABR can eat me with soy sauce! Sorry rant off...

Anyways...solid lifters huh? How often do you like to pop the valve cover off to adjust the lash on them? Every oil change? Say every 3k miles? No one really messed with them because I have yet to find one competent individual who can adjust the lash correctly without making all this ratchety clack sound under the valve cover.

I'll go back to my hole now.

I used to adjust them on my '59 bug does that count? :P

I didn't know 59' bug had a forum to gripe when something went wrong, maybe I should dig alittle more.

"Hello everyone, I recently did a valve adjustment on my 59' bug and now it's throwing a P0300 code. Can anyone here help me? TIA."

haha, honda vtec heads have to have the lifters adjusted. I do it maybe once a year if that. The noise isn't too annoying. :P

I'm resurrecting this thread to share some first hand information that maybe usefull to the rest of you.* When I started this thread I was looking for this kind of info.

Solid lifters do not work for this engine unless you are running a stand-alone engine management.* The noise caused by the solid lifters is picked up by the knock sensor and diagnosed as ignition knock.* The stock ECU then retards timing severly causing a great deal of power loss (~100HP).
