850CC Head
Turbo Mini Forums

I'm trying to find someone that has an 850cc head that I can buy/have that I can put right onto my car, tighten everything down and drive the mini. If anyone has one, please let me know, I can pay. I'm in the United States though, so you have to be willing to ship(which I'll pay for).

Thanks!

what heads were on the 850's?

"did you know you can toast potato waffles?"

I reckon you should shove a k100 head on that girl. Think thats what the first bmw twinnie head was put on iirc. :)

if you specifically need an 850 head, i cant really hep, but if your just desperate for something to bolt on and go, then i have many std 998 engines knocking about i can steal a head off for you

"did you know you can toast potato waffles?"

What mod's would I have to do to the 998 head? As long as I can get the compression right a 998 head would be fine, but I imagine with the amount of machining needed I would need to skim as much as to the oil gallery which would have to be brazed up and then re drilled?

Oh, and a 12A1456 head is what was on it, which is the original casting number. It's for the 85H motor, not the low compression motor.

As far as I can remember, 12A1456 is just a standard small bore head, used on 850's and 998's.

You may be right, I haven't had much time to research it yet, but I think I may have read that somewhere in the past day or so... Anyone got one that doesn't need rebuilding?

-James

surely if you are willing to import a lump of cast iron it would be worth throwing that at the head you already have to get it to a better spec? just my 2c

I'd be spending $700 just to rebuild it to stock, and I can get Keith Calver to do one up st 3 with larger combustion chambers for $1000(This is U.S. dollars) but I need the mini back on the road right now, as she's my daily.

-James

good point.. and huge rebuild prices^^
Would be intreated in what shipping sets you back, im a fair ways off from uk myself. good luck.

for a head, I can get it for about 110 pounds, which is roughly $180 U.S.

Which head would be better for an 850cc?

-James

Nothing that's bolt on really. You'll need some skimming etc. on the alternatives.

Then I think I'll stick to basic 850cc right now. Anybody got either 12A1456 or 2A628 that is ready to go? And willing to ship to the U.S?

-James

I comfirmed chamber sizes with Keith Calver, and he thinks a 998 head would be just fine. With that in mind, does anyone have either the 850cc heads that I mentioned, or any 998 heads that are in good nick that I can have/buy off them? That CAM4160 head would be nice, if anyone has one in good condition. Let me know what you've got, I do need to be able to just drop it on though(fit and drive-esque head if you catch my meaning). I can do a skim if need be, or a valve grind, but the seats and valves need to be in good condition. If you've got something that fits the bill, lets talk cash, and how I get you you're cash and you get me my head, i.e. ups or some such(fed

Get an unleaded one whilst at it.

If it will take a 998 head, tehn this should fit and offer a bit more performance...

I might do that.

If he won't post to the US, get it sent to me and I'll forward it on for you.
