Okay, according to this info, if we're using a 1UZ piston, we've got 5.8mm between the wrist pin and the oil ring. If we use a 3UZ piston, we have... a whopping 10.8mm! Is that right? The top ring is obviously moved higher up on the 3UZ, and otherwise they look pretty much the same. I think...

There is a guy selling the Eagles on ebay for $340 right now. Since he's got rods for a lot of imports, I'm sure he's a dealer and will probably put another set up after this auction is over, or maybe he'd be willing to sell two for the same price. Either way, it's a shot at getting the whole...

Ebay These are like factory Mitsubishi MLS head gaskets, in that they have a coating.

You have to have a way to get a crank signal to the box. You remove the distributors and the box fires off the crank sensor position.

Pushrod engines tend to be 2-valve engines, which helps them produce more torque down low (the 4-valve design would be why most DOHC engines make their power higher up). Many people like the low-end torque of pushrod motors for their daily drivers. I personally am not a big fan of the big...

I decided not to resleeve the block. I don't think the large pistons would work well with the head designed for a smaller combustion chamber. The 4g63 rods come in two flavors, and they are exactly the same except the 1g rod is 1.140" wide with a 21mm wrist pin and the 2g rod is 1.040" thick...

I forgot to mention, I also got 8 450cc injectors from the same fellow for $100 shipped. These might require a little modifying (they are from the same engine) but should be PLENTY of fuel for my needs. The reason I want to use these rods is because they are cheap. A set of Eagles run $360...

I think that having a longer divider wall might help direct the flow into the combustion chamber, based on the fact that it has more time to stabilize before reaching the valve. That's purely a guess. I wish you could scan those pictures because I'd LOVE to see them. I agree that the best...

So we need two PWM signals (thanks again for filling in the voids that I completely forgot about). We need 4 cam sensor inputs. And we need to take that data and use it to create a table that will control the PWM signal. Is it possible that we can split the same PWM signal to both actuators...

Ammonia is NH3. NH4-OH is ammonium hydroxide, which is formed when you add ammonia to water. Ammonia is a weak base and therefore you will have an equillibrium on both sides of the equation. The equation being: NH3+H2O <-> NH4-OH We use ammonium hydroxide for pH control in the primary...

I don't see why it wouldn't work, but again, you'd have to control the pressure on both sides, and you'd have to make a new heat exchanger setup. Keep in mind that this will be a lot easier with journal bearing CHRAs.

The BMW 850i and 850Ci came with a 5.0L SOHC, 300hp engine. The CSi came with a 5.6L SOHC engine, which I think was significantly different than the 5.0L. It was basically BMW's race version of the V12. BMW upped the regular V12 to 5.4L at some point in time. I have a friend with an 850i with...

I found someone willing to sell me two sets of rods for $175. So this way, I can wait til later to upgrade the rods on my Eclipse. :)

There are a number of people driving around with N1 motors in their cars. Those are a lucky few, purely because of the small volume of production. This thread is getting pretty funny. I think all of this just goes to show that the engine out of context is worthless. While there ARE better...

Ah. I'm not thinking again. I forgot about the scissor gear. Okay, so the best option is definitely to regrind the stock cams and keep the VVTi. Can we use a stepper motor and use a PWM output to control it? The AEM has a PWM output, right? I won't be using the AEM, but hopefully I can...

I think the problem with cryo treatment is, while you increase the hardness, you decrease toughness and ductility. You may prolong bending a rod, but when it fails, the destruction will be worse. That said, I don't think it would be necessarily a bad idea for rods. I'd like to find out more...

Ah, I found a picture. I didn't quite remember it correctly, but this is it: http://www.theoldone.com/articles/badtothebone/clicking_clearance.jpg I really think that more dimples over the whole surface area would promote better mixing without impacting flow much at all. It seems like we...

Another thread resurrection. As many have said before, I agree that mirror-finish polishing is detrimental for fuel/air mixing. The better the mixing, the better the burn, so I think we are taking a step backward with just a mirror polish. In analyzing the effects of the polish, we must...

Okay, I've been looking at a few pictures, and the only difference I can find with the VVTi cam is the oil gallery in the #1 cam journal. Call me stupid but this looks pretty damn easy to replicate, as long as care is taken. On the 2g Eclipse, the cam angle sensor was on the end of the intake...

Do'oh! I was thinking VVTi was like V-TEC with separate lobes. It's obviously not. So all VVTi does is change the cam timing on the fly? On the 3UZ, the system is a sudden switch, right? Not a gradual advance in timing. Is this only on the intake cam or the exhaust cam too? I really like the...
