To be fair, Hbz has slid a bit towards nwn as well. Some unprovoked flat out rude and disrespectful behavior from even well established members(admins even) has been happening there. I understand light chastisement for not doing research, or for being a bit obnoxious, But i recently saw some language that i found flat out unacceptable. I like having Hbz as the respectable joint, and Ratsun as the sports bar. Thats all beside the point, Datsunoob's assessment of JDM510 is right on, even though he does not make his point with elegance. I mean... come on, he has JDM in his title! :D Joe

Nismo.. I have the same box, but with a SS top and no hutch. Too bad it's 400 miles away...

The problem is that in order to avoid engine misfires, pinging, detonation, all of that neat stuff on a higher compression engine, you have to have different tuning. That tuning includes different timing curves, different fuel curves. Even at part throttle low load cruising speeds, you will be using more fuel at the same rpm, because you will still be producing more heat(power), and higher cylinder temps, thereby, higher nox. This is a physics, thermodynamic, and chemistry thing, these rules don't change. If you are concerned about emissions, get a late model engine with all of the emission controls. The lsx series of engine produce great horsepower, and are more thermally efficient than engines designed in the past. The move towards direct injection gasoline engines is nice, as you can more finely control fuel timing. So, I would wait a year or two, and see how reliable the direct injection chevy v6 is. I would like to put one of those in my Z, 300 hp, excellent efficiency... near 30 mpg in the new camaro is pretty impressive. My point is that changing compression ratios is not the real answer to nox emissions control. Cylinder cooling, and friction reduction will yield increased efficiency, allowing increased compression pressure, whilst achieving lower emissions, and using less fuel. Joe

Datzenmike, exactly.

If your torque output on two engines is the same at the same rpm, then you do not have different compression ratios(in a perfect world)... An engine is just an air pump. Power production requires heat, fuel, and air. More power generally require more heat, unless you make it more heat efficient(less drag, lighter valve train and crank and less cylinder friction, which is why Benz has silica coated cylinders) Higher compression means just that, higher compression pressure, higher cylinder pressure, higher cylinder temperature. If you want to cool the cylinder, you can go with alcohol/water injection, But this tends to pit the cylinders and cylinder walls. If you are looking to have increased power, and still pass emissions easily, then turbocharging is the easy answer. You can adjust boost pressure, timing, and fuel curves, and if you have a shop that doesn't care much about visual inspections. So, you can reduce nox emissions at will. I fail to see the point. My point is simply that the logic behind your thought process is flawed. Joe

uhhh.... no. Increased compression creates higher cylinder temps. Higher cylinder temps increase nox. You do not "use less fuel" with higher compression engines. You use a fuel with a higher resistance to combustion. or a higher octane. A higher compression engine does not use less air. compression ratio is simply a mathematical function of bdc volume vs. tdc volume. you can have an engine with 8.5:1 compression, pulling the same amount of air in per stroke as an engine with 12:1 compression. So, I don't know what you are trying to suggest. Everyone already knows that an engine with higher compression is more efficient, and turbo charging increases the compression pressure, while also working well as an altitude compensator. Anyhow... Fail

When it comes to engine rebuilds, if you cannot afford to do it right... Then maybe you should not do it at all. Get GOOD parts, from reliable trusted sources, yeah, you are going to pay more for the good shit, but the results will speak for themselves. Cheap shit always gives you headaches. Joe

If you only spent 2 minutes there, then you obviously didn't see this one. They are not all funny. Like Kamikazi, you cannot always succeed at being funny. :P

*lurks about*

Tasteless sites? You can taste webpages? Weird... "The snozberries taste like snozberries" And I don't care what you think, this shit is funny.

Thanks for the love Kazi. It wasn't that bad. If you want some real c/l funny go here : Don't Even Reply

I think it might get a chevy v8 and 700r4 or 2004r... eventually.

This one is not quick, not by any stretch of the imagination. It might have 40 hp.

I bent a valve or two in the V8Z, and i just got a job working for the Census, so I needed some cheap, reliable wheels. So enters my new benz, Her name is Blitzkrieg, and she is quite slow. She may have trouble with making it over anthills, but she has new tires and excellent brakes.

Uh... what?
