So I'm wondering when most of you are seeing that O-ringing the block becomes nessasary.
Right now I'm into 700+WHP and im having issues with the head lifting. I am on standard ARP head studs and a commetic head gasket on a 2.0l with 9:1 compression with CP pistons.
I'm trying to decide if switching to L-19s is going to be enough or if i should go ahead and o-ring the block at this time because I plan on having more power throughout this season.

The people on here that are running over 700hp what headstuds/ head gasket/ and if there block is o ringed.. etc etc.. If anyone has knowledge of o-ringing block or if there is a thread that they could direct me towards, that would be great!

Basic car info is 37r, 2.0L, probably going to switch to vp import or C-16 and I want to be able to run 38-40psi on it with nitrous and possibly as much as 100shot. Just trying to gain some knowledge on what other people are using specifically with nitrous applications. I know "ILLEGAL EVO" was running a similar set up in that yellow car, so if anyone knows what his motor build was like that could help.

Thanks for the space...

p.s. hopefully this post makes sence i got interupted about 75 times while trying to write it so i'm sorry if its hard to understand..LOL

 

Sorry i'm not quite to your hp level but my car puts down over 500hp on a MD.

When i put the motor together i was forced to make a decision as to o-ringing or not and what studs to use.

I figured i would do the L19 studs and o-ring the block just for safety sake as well as being able to push more hp outta the 2.0L in the future if i decide to swap turbos etc.

Don't know if this is an option for you but what about o-ringing the head? Or is the entire motor coming out?

I know Buschur did a head for one of our 2G DSM's.

Edit: We run our cars on boost alone no N20 for now at least .....as well as oem HG's

 

thanks for the information!!!
Anbody that has experience with o-ringing these engines there knowledge is welcome!!
I'm not sure if o-ringing the head is an option has anyone done that one here before?

I believe Buschur O-Rings the head

 

We have Buschur do our blocks w/ o-rings for anything 40+psi or larger than 67ptrim.. I prefer to always oring the block and leave the head alone.. O-rings IMO last much longer in iron than they do in aluminum.. if you ever blow a head gasket its a pain to have to always rering the head to resurface it..

We have not had 1 issue with our BR block w/ orings.. We used standard ARP's also w/o an issue but switched to l19's recently just for peace of mind..

 

Thanks mike!!
It sounds like we are going to do the o ringing on the block. What I'm wondering is do you have to run a different head gasket with an Oringed block? If so who makes them?

thanks again,
Mark

 

Like i stated in my prev. post my block is o-ringed and i run an oem h/g

 

i think your problem is the cometic head gasket.i have an hks and no problems to 38psi.

 

Use an OEM steel gasket..

 

Lol oh yea, I guess I should have read that again.. DEE DEE DEE..

You havn't had any issues running the stock one with 500+ hp? I know bushur in his RWD car was running a o ringed block and a stock hg on it and it was running 7's i think at the time.
hmm

I believe almost everyone that is making big power (700+whp) is running o-ringed block and stock headgasket

 

on the 67p trim making 735whp i was running Buschur 2.0L Crower/JE motor w/o orings and didnt have an issue.. small t3's IMO are ok unless your spraying i guess.. a big 42r is a new ball game when it comes to 40-50psi and cyl. pressue..

 

thanks a lot guys that definatly anwsers what i was wondering..

 

if you do o-ring the head have Shep do it. he has a machine setup just for this job and if the head ever needs resurfacing they can go back in and recut the receiver for the o-ring.

 

ya I agree, its not needed around the power levels of most T3 setups, but with some added cyl pressure via nitrous or high boost (38-40psi), it might be a good precaution. I think the 700hp area is definitely a good starting area for 0-ringing the motor
