QUOTE (dragoon20005 @ Yesterday, 7:52 PM) | looks like it meant for NA setups based on that compression ratio
with that upgrade it can easily hit 9k rpm and the max rpm is 10k rpm
but to TC it you might need to lower the compression
but then again the new ver do look sexy with all those joints and the timing gears for the camshaft instead of the chain system |
No, I meant even on NA setups 11.0 is really pushing the limit over here in terms of being able to drive on regular pump gas. Especially with old Z engines, though this head might have a better design than in the 70's... still...
I'd want to run that engine NA with triple Mikunis/OER's anyway... good god would that be awesome...
QUOTE (dragoon20005) | whats your RON rating?
in my country we have up to RON 98, RON 95 & RON 92
maybe its for their RON 100 in japan |
87, 89, 91 (93 where I live).
Yeah, our gas is shit.
QUOTE (S12 Drifter) | thats a srupid design they still maintain the same side exhaust/intake mani setup.
as for the 11.1 nothing a thicker mls head gaskets wont handle along with head studs.
|
No. Just... stop talking now...

Take a look at RON vs. AKI and (R+M)/2. Generally, converting American Octane into RON bumps it 4-5 points. So 93 would actually be 98ish RON. Also, cool, you got ~420hp out of an L32 (btw, who the hell uses PS still? that's just stupid). Now make enough of them that you don't have to be super wealthy to buy them, you just have to be REALLY dedicated to your cars, and maybe the Z world will start caring more. Also, those side by side shots of the old vs. new. Which one is running the gear driven cams? edit: found it, the triple gear front setup is the new one. EDIT again: Found a metric SHITTON of high-res pictures of this from a guy that saw it in person, DLing and ULing now. Also, word on the gear drive: WAY less wear than a chain drive, don't have to worry about tension/routing (biggest issue with making them DOHC), and VERY, VERY little slop at room temp.

Oh.... derp. Guess I should have done my homework instead of assuming the ratings were identical.

Seeing as we're a pretty niche market, I don't see that happening. Ever. Sad but true. QUOTE | Also, word on the gear drive: WAY less wear than a chain drive, don't have to worry about tension/routing (biggest issue with making them DOHC), and VERY, VERY little slop at room temp. |

QUOTE (Oddmanout84 @ Jul 26 2012, 12:39 PM) | As much as I'd rather an opposite side In/Ex setup, the L6 is a product of its time and still works.
*best youtube link ever was here*
Obviously, when this 240z with an NA L24 could probably kick the crap out of just about any average 350z, let alone a Z31. |
Jesus f**k my ears just jizzed all over the place, now I need to go buy new headphones. Thanks a freaking lot, jackass. Oh and as for that DOHC custom head thing, yeah, old news, saw it in person, yadda yadda. MSA Z Show from 2009.
