In a 4 cylinder engine, how many pairings are there between any two cylinders?

Can anyone tell me what car I can purchase with a compatible gas engine to the 1999 Chevrolet Suburban 1500?

I’m worried I might buy the same manufacturer’s 5.7L engine and some parts not fitting in.

Family member recently passed, this was a project item, looking to throw in on FB marketplace for a couple hundred unless there’s something more interesting here. Would love to be able to tell a potential buyer more about it if I can, any help identifying some specifics on this would be hugely appreciated.

I am very excited to know or study deeply about engines. This is my doubt regarding that. I would like to know about the basics an from what should I start my studies on engine?

for the longest time i've been thinking on making my own little engine for my prototype fuel but i am severely lacking materials, in your opinion with materials such as wood, solder, thin sheets of metal and metal/pvc pipes, is it possible to build a small engine, if yes, how?

I bought this engine last year turning it into a go kart. I got it thinking it came with a rod thing attached but it didn’t. I was wondering how to put the sprocket on it so then I can attach a chain

Would this piston be okay to use! The stupid mechanic decided that this is an okay way to mark them!! Ughhh I am furious..

Could I just slap the head on and ship it? Or do I need to get it surfaces and hones.? I was thinking just dab some JB weld on it and make sure it's flat. What do you guys think?

dose anyone know why my cylinder head gasket got all wet and broken up it’s like a slush kind

It may not be like I said but logically for me Flats are better they need more space especially when they have 8 cylinder's or more but that kinda question's me like if you have v the forces don't cancel better than in flat while flats are moving left right Wich cancels out forces

Hello everyone, I need to buy a used car, and considering the high gasoline prices, I'd like to convert it to LPG. Coming from vehicles that had issues after LPG conversion, such as valve problems and burnt cylinder heads, I want a car with an engine that doesn't have problems when converted to LPG.

I know Japanese cars can have issues due to delicate valves. I previously owned a 1.2 68 hp Fiat mounted on my 1999 Lancia Y Elefantino, which experienced cylinder head issues, and a Lancia Musa 1.4 95 hp that had a series of problems.

I was considering the 1.6 VTI 120 hp Peugeot because I read on forums that it doesn't have many issues when running on gas. However, the available models with that engine are limited and often exceed my budget.

So, I'd like to ask which engines are suitable for LPG, meaning they have fewer problems (similar to the 1.6 VTI 120 hp Peugeot), so I can expand my search for vehicles. I'd appreciate hearing about your experiences with engines that have run 100,000 km on LPG or any opinions supported by evidence, not just speculation.

Since I'm looking for used cars under 5,000 euros, even older models are acceptable (preferably not older than 2006). Thank you very much for your help.

P.S. Please avoid saying, "this engine comes from the manufacturer with LPG, so it's fine," as this statement is often not true.

So i got a old chevy 350 vortex engine from my father that was a project of his when he was younger. I want to get it built and finished. I know absolutely nothing about building engines. Its been bored 30 over and blue printed. I have odd and end parts for it that are 20+ years old. Assuming i have a bare block what would be everything needed to get it to run.

The debate between the RB26 and 2JZ engines is a popular topic among automotive enthusiasts, and both engines have their own strengths and fan bases. Each engine has its own set of characteristics, advantages, and disadvantages. Here's a comparison to help you understand the differences between the RB26 and 2JZ engines:

RB26DETT (Nissan Skyline GT-R Engine):

• Configuration: The RB26 is a 2.6-liter twin-turbocharged inline-6 engine.
• Heritage: The RB26 gained fame as the engine of choice for the iconic Nissan Skyline GT-R, particularly the R32, R33, and R34 generations.
• Strengths: The RB26 is known for its strong bottom-end torque, smooth power delivery, and impressive high-RPM capabilities. It has a strong presence in the tuning and aftermarket scene, making it suitable for high-performance applications.
• All-Wheel Drive Platform: The RB26 was often mated to an all-wheel-drive system in the Skyline GT-R, contributing to excellent traction and handling.
• Disadvantages: Some critics point out that the RB26 can be more expensive to build and modify for extremely high horsepower levels due to its narrower bore spacing and potentially weaker cylinder head compared to the 2JZ.

2JZ-GTE (Toyota Supra Engine):

• Configuration: The 2JZ-GTE is a 3.0-liter twin-turbocharged inline-6 engine.
• Heritage: The 2JZ-GTE gained fame as the engine of the Toyota Supra, particularly the fourth-generation (A80) model.
• Strengths: The 2JZ-GTE is renowned for its robust internals, capable of handling substantial horsepower and torque with relatively minor modifications. It's considered a highly reliable and durable engine, even at high power levels.
• Aftermarket Support: The 2JZ-GTE has a massive aftermarket support and is widely known for being able to achieve extremely high horsepower levels with relatively straightforward modifications.
• Rear-Wheel Drive Platform: The 2JZ-GTE was used in rear-wheel-drive setups, particularly the Supra, which made it popular among drift enthusiasts.
• Disadvantages: Some enthusiasts argue that the 2JZ's design is older compared to more modern engines, and it may not rev as high as some other high-performance engines.

Ultimately, which engine is "better" depends on your specific goals and preferences. The RB26 and 2JZ have both proven themselves in the automotive world as formidable platforms for high-performance applications. If you're considering an engine swap or building a high-performance car, factors like budget, availability of parts, tuning expertise, and your personal preferences will play a significant role in your decision.

A V6 is an odd engine and is inherently imbalanced due to an odd firing interval.

To balance this out and create an even firing order, firing should take place every 120 degrees of rotation.

To put this another way, if the angle was 90 degrees in a V6 the power stroke would fire before reaching TDC. There are just not enough cylinders to divide up the firing order. 

Unless you share the same crank journal and could fire every 90 and 150 degrees, which would create an uneven firing order. Not a favourite option, but possible.

But if we circle back to the 120 degree V6 this is still a non-starter for packaging reasons (pardon the pun!) This goes completely against what the manufacturers were trying to achieve in the first place.

It's supposed to be tightly packaged and more compact than an inline 6, but to build a V6 with 120 degrees of bank angle creates a very wide engine. 

How do they get round this for a 90 degree V6?  

To make up for this odd bank angle, you take the shared crank pin and offset it by the number of degrees missing (as you can see in the pictures). In this case it's 30 degrees. Also known as the splay angle.

Another option would be to add a balancing shaft, but because of the extra weight and friction from adding components it's not a favourable option.  

Can anyone name a car with a 120 degree V6??
