The free version of Avast has been going strong for me for about three years and counting.

This is awkwardly true.

But then it isn't a four door E46 M3, now is it? He says he did because of insurance costs, but I'm pretty sure he had other intentions in mind. Coming from an E46 sedan owner, I think it is kick ass, and if I had his $ and his friends, I would have done the same...

Do you really have a swap manual!?! That would be way cool, not that I am planning a swap, but it would be awesome to just read through that thing. EDIT: Got way tooo excited about the S52 into Z swap that I didn't even read the post correctly! +1 what he said!

"With L28's being able to rev to 9000+, and a destroked 2.5L (L20A Crank) being even more revable, along with a larger bore for better valve unshrouding and high rpm breathing...." L20A not so easy to get in the states...I personally have never stumbled across one as easily as a L24 crank. Once again, R/S ratio...no answers on that front....incomplete theoretical arguments are what I am trying to have answered... Some info on what I was reading when I first posed the questions. http://forums.nasioc...ad.php?t=424283 http://www.stahlhead...od%20Length.htm Another question is, if you do the math, using the L20A crank in the L28 block gives you almost the same results as using the L24 crank in the LD28 block without spending a fortune or lots of time finding the crank. I know you might have easy access to these cranks as you are a very well traveled man and have many personal connections to Nissan and L6 gurus from your stories, but from what the OP has available to him and from what we mostly have available here in the states, he might be able to pull off a motor that mimics your 9+k shifting Bonneville car at a cheaper price. (If I understood it correctly you built an L20 for class restrictions, might be wrong) Thus my question as to why it isn't more popular.... As for the comment about larger bore, this hasn't been proven, I've read the thread about the 4.0L L6 and there doesn't seem to be a conclusion. Only a statement about sonic testing many blocks with negative results, but same could be said about regular gasser blocks. I am thinking knowlegably, maybe I should pose this question in a thread about internal combustion engine thermodynamic efficiency and how the compression cycle is effected by slower piston speeds (longer rods, shorter stroke). Another point of reference....I am by NO means comparing the flow numbers between L series heads and RB heads. But the idea is very similar L24 Crank 73.7mm LD28 block bored to say about 86mm Looks really familiar. RB25 - 2.5 L (2498 cc, bore: 86.0 mm, stroke: 71.7 mm) RB26 - 2.6 L (2568 cc, bore: 86.0 mm, stroke: 73.7 mm) LD28 Block L24 Crank N47 Head Z20E Rods L28 Flat Tops 1mm Head Gasket Rod/Stroke Ratio:2.069 Bore/Stroke Ratio:0.857 Static Compression: 9.471 With a displacement of 2.569L and 0.000 Deck clearance I am also not arguing the fact that the L28 is bigger, has more stroke so creates more torque motto, this is all a learning expierence, nothing is the best and nothing should be put down ( if this were the case you wouldn't be posting on hybridz now would you ) As part of my learning experience, please explain why this wouldn't be a good candidate, even as a turbo motor.

Are those Appliance wheels?

Way better rod/stroke ratio which may or may not lead to less detonation. (Probably not true, but read an incomplete argument on this site about the possibility of it lowering detonation) Not saying that it is the holy grail here, just saying that I wouldn't just think of it as a crap idea. With all of these LD cranks being pried out of these block, using them for their extra deck height might be good. If anything else you can still build another L28 with a better r/s ratio. Like you have said before, it has all been done, I just wanted to know why it isn't more popular.

I posted this in another thread...I still believe that it would be amazing high revver. LD28 Block L24 Crank N47 Head Z20E Rods L28 Flat Tops 1mm Head Gasket Rod/Stroke Ratio:2.069 Bore/Stroke Ratio:0.857 Static Compression: 9.471 With a displacement of 2.569L and 0.000 Deck clearance. Might be good for a high revving option.

Wow....that thing is beautiful!

The top itself doesn't look very good, but wow, the body lines just seem to pop on this drop top. This is not my AD, just wanted to show you guys this nice Z. http://cgi.ebay.com/ebaymotors/AWESOME-1-KIND-1976-DATSUN-280Z-ROADSTER-351-V8-/120571851368?cmd=ViewItem&pt=US_Cars_Trucks&hash=item1c12a47268

KA24E not DE

Wow! Talent...
