I was wondering does everyone have a DOHC engine in their acura.....

yes i am a noob when comes to other peoples engines

 

unfortunately no. not all of acuras engines are dohc. 3g tl are sohc

 

I think the only DOHC V6 Honda/Acura makes is the NSX engine. Someone correct me if I'm wrong.

Our cars are SOHC.

 

so this is a SOHC

 

The old integra

 

yes.

 

Even though you have 2 cams, it's a SOHC, as in Single Overhead Cam. There is only 1 cam over the head. A typical V8 has one cam in the block and pushrods activate the intake and exhaust valves for both heads.

In a sohc, the cam is on top of the head and is directly actuating the valves, both the intake and the exhaust. A DOHC has a cam for the intake valves, and one for the exhaust valves.

A good way to think about it is if you've ever seen a SOHC honda civic motor. It only has one head and one cam. Makes sense, right? Think of our motor as 2 of them in a V configuration, with one cylinder chopped off of each head.

It's more complicated than that, and a lot more efficient, but that's a good way to think about it.

A SOHC motor with 1 head will have 1 cam, while a SOHC motor with 2 heads will have 2 cams.

A DOHC motor with 1 head will have 2 cams, while a DOHC motor with 2 heads will have 4 cams.

Now, think about how GM is going to have a Dual cam-in-block V8. Not sure if they are still pursuing it, but they thought about it.

 

Old integra wasn't a V6. It is a DOHC, but its an inline 4 cylinder. I always thought a V8 based off of 2 B series heads would be pretty nice, but I don't have the stuff to fab a block.

 

the part you are picturing with the "acura" on it is the intake manifold, the cylinder heads are on each side(front and back) of the intake mainfold

 

Darn, was hoping for this thread to be a successful DOHC swap. Oh well.

 

The J series is SOHC

 

yea, the only V6 Honda Motor with DOHC is the NSX (C30a/C35)
