best ported head?

[rampage idiot]

Deluge I have been wanting to ask this question because I do not understand the theory behind these cylinders you are telling rampagemt he does not need the crank but both of those cylinders are machined for a 2mm sroker how does this work without the crank and how would you get the squish correct ? I am confused because I was gonna ask the same question as him because I am thinking about getting a ported cylinder for my MT that has a 30.5 stock motor in it

 

[GTS 666]

The stock 30.5 already has a 2mm crank so there is no need to replace it.

 

[Deluge]

Yep. The stock 30.5 has a +2mm crank.

 

[rampage idiot]

Well that answers alot thanks alot guys

 

[Deluge]

No problem, dude.

Pros and cons if any OBR vs ESP

 

[Guest]

I don't think you can go wrong with either.

 

[rampage idiot]

Thank you 4 the input

 

[Deluge]

They're both awesome. My next engine build will be an OBR. I'm completely happy with my ESP, though.

 

[rampage idiot]

Thanks Deluge

I am making my order Wed for the esp 30.5 top end that was mentioned on page 1 along with a new head gaskets and cy pin bearing is there anything else I will need? I don't have a flywheel puller and will wait on that as I just remove head correct? I watched tbe team fast eddy engine rebuild series and the only ? I have is the measurering squish. Will it need to be done? Sorry for the questions. This will be my first time taking apart motor minus the cosmetic stuff.

You will need a digital caliper and a .030 solder. Here is a thread about measuring squish....

Alright will be picking up the solder and borrow a digital caliper and hopefully figure the squish out

 

[Deluge]

You don't need the flywheel puller to install the head kit. You should check the squish anytime you install a new cylinder or a thinner/thicker cylinder gasket.

 

[rampagemt]

Okay. I'm dying to try the top end you recommended fron esp deluge. Should be a beast in my dune runner. Just need the beltdrive and it should be nuts. Hope is a lot better then stock. Just wanting to upgrade to more power until i get my obr engines.

Deuge you will appreciate this just got off the phone with Doug at ESP motors he said throw away the gasket that comes with it, does not hold up, said to use stock zenoah or if you want to lower the squish use a copper gasket. Seems like a real nice guy definitly knows his stuff, He said to make sure I open the exaust manifold on the top and sides to match his exaust port

 

[rampagemt]

Rampage idiot what do you mean open up exhaust manifold on the top and sides to match his exhaust port?

 

[rampage idiot]

You want to have the hole in the opening (the part of your pipe that bolts to your motor) to match the exaust port in the cylinder , what I mean is when your exaust comes out of the cylinder if the opening in your exaust pipe is smaller the exaust will bounce back into the cylinder. ESP ported the cylinder if you want the job done 100% correct the exaust holes should match, just being a stickler for detail, I port car engines all the time

 

[rampage idiot]

rampagemt here is a pic of an old exaust pipe the rectangel shaped hole is the one you do not want to be smaller than rectangel hole in your cylinder

For sure, dude. Doug is a cool guy. Never had a problem with the Zen gaskets.
