best ported head?

[rampagemt]

Alright guys I wanna turn more rpms from my stock 30cc 2 bolt I really wanna get the 29.5 cc prostock from obr but funds are kinda getting low. What's a good head for this motor for more rpms. I am sorry for asking its just I have never rebuilt an engine tho I have watched fast eddys series. What would be a good ported head to get and would it also be smart to get a flywheel puller from Hpi. What else would be needed? My main goal is to get this sucker rippin cuz my 2 buddys got bajas and wanna rip it up past them. Right now I have a rear dominator which I know isnt the best for rpms but i really like it and a 7500 spring. I plan on swapping the 29 and 31 gears around for more speed and then a new head ! Thanks for all the help already guys and my ?s keep on coming haha

What vehicle?

Forgot to say it is for the dune runner!

If you want to stick with OBR, this is what I'd get.

Race Ported 2 Bolt 30.5cc Top End

If you want to try ESP, this is what I run and it's a beast.

ESP Mod/ESP CHAMPIONSHIP PORTED GP290 36mm kit (You don't need the crank)

And yes, the flywheel puller will make life easier.

Alright thank you very much im liking the esp see how that does. Are those gaskets it comes with ok or should I get copper gaskets? Thank again

 

[Deluge]

Skip the copper. The gasket they give you in the kit looks a little cheesy, so I replaced it with this one. Haven't had any issues with it. Might want to pick up a couple.

Also, I don't remember if they include a pin bearing with that kit. May as well replace it while you have the piston off.

Thanks Sooo much you rock!!! Isn't stock HP from these motors like 3.5? If so that's a nice improvement!!!!!

 

[rampagemt]

And what are you running that head on?

 

[rampagemt]

Does the torque change from the 2 bolt to 4 bolt on the head of motor? And isn't there a engine torque picture around here somewhere

I'd say around 3 HP, stock. ESP makes nice head kits.

Running it in my MT with a DDM side Dom. It's a beast.

Torque specs are the same.

 

[rampagemt]

I shouldn't have to change bearings on crank with this kit right? Motor has less then 2 gallons ran. And if I like it enough might have to get more of those kits

 

[Deluge]

No. If you buy the kit without the crank, you don't even have to open the case. Just swap the cylinder and the piston.

Awsome dude thanks alot will be a piece of cake

 

[Deluge]

It's pretty easy. Let us know how it goes.
