As a guy who will never see this kind of boost I don't need fix. But r u really saying people attitude was bad so u not sharing fix.

So we r the ones with an attitude problem.

OK sure

Seems like the adult way to handle it to me.

Then you keep posting to what rub in our faces that you know something we dont.
You came here for help but will give none. Yeah that's the way to live.


Shouldn't you be out pushing old ladies down for sport or sucker punching people on YouTube for amusement

"Not keen to share the fix due to condescending attitude Chris has received on here, all he was after was shared experiences."

Fuck off.

It's so great having Fael back. I'm laughing my head off.

You don't know what you had until it's gone :likecat:

BP Head Lifting
 

Please tell us about the fix for the problem we don't ever have. I'm on the edge of my seat.

It's obviously the same fix that 1200 horsepower supras use!

Because 400 whp miata = mega supra.....

In all honesty, two epic builds.

Non conformance to grow the community through shared experience- not mega, kinda douche-y.




And, am I the only one who noticed a pattern?

"Hey guys, lifted the head. Anyone have any fixes"

No, we dont lift heads. Other problem?

"No, it's a known issue, and my friend knows how to fix it"......

Oh, wow. Usually we see x,y,z causeing issues. You sure it's the head?

"Yes, I have direct experience with my friends build doing the same thing, and he fixed it. Don't tell me I don't have this issue"

Wow.

Friend "here's my admittedly baddass build doing the same thing. I know how to fix it, but I don't want to share"

"Yea"

Well, how do you fix it?

"Don't want to share, you guys weren't nice enough, but I know how to fix it"


......






If you had direct experience with the problem, and with a solution to the problem, why the f*ck did you post asking for suggestions?

This whole thread is about boners.

If your boyfriend can blow that hard, surely he can suck just as well.
Might help lift the head sooner.

If you copper plated your hg you wouldn't have had that problem.

I said we had done some mods to try and fix it but wasn't tested yet and asking if anyone else had any experiences with head lifting

Then the answer is no. We don't have experience with head lifting. Experience with several dozen other things, but not that.

Plenty of people here with stock head bolts and plenty here with arp head studs, so it's not the fasteners.
Plenty of people here making your power level, so it's not the power.
Nearly everyone here runs the stock HG, so it's not the head gasket (unless you're running a weird aftermarket one that isn't actually as good as the stock one).

Unless you guys are willing to tell us more about your issue instead of asking making vague assertions and accusing us of being unpleasant/impatient/etc, we really can't help.

Also, I would add that blowing coolant with no other symptoms does not necessarily mean your head is lifting. A blown HG can do that just as well. I once had this on a 10psi car -- and it would only do it on track -- never on the street.

I'm not saying it's not head lifting in your case, just saying that blowing coolant is not determinative.

So dud u fx th head lift

but the $10 ebay Evergreen brand HG was much cheaper.

No issues so far, had the head skimmed and the head stud\nut bosses machined to remove where the washers had dug in, used the bigger arp washers and tightened to 90ft/lb, doesn't push any water at the moment but have only had it up to 20psi ran out of time to get it tuned again before an event here.

Confident it is fixed tho, JRCOZY motor has seen 30psi and a few 1/4 mile runs and no longer pushes water.

congratz u r also like 1/5 miata to ever push above 2bar. oh wait 323 thats more manly nvrmd

mph in qtr plz

JRCOZY Best - 10.79@136
Mine - 11.2@125 - i think

I've been absent, so pardon my ignorance. ...

But was the major breakthrough, to not use the little ARP washers, but the stock size ones instead? Or are we using fender washers now?

Pretty much, my head had big marks in the bosses where the washers sit, where they had compressed the materiel and sunken in, whether you want to believe that the head lifted and caused the issue I was having or not, this shows there is something not 100% right, others have found this problem with many other engines 2jz's seem to be the most documented or most prone to it, arp actually ships the 2jz kits now with the bigger washers as standard

damn fast
