Head Gasket Choice

[juicy3]

Hey guys,

Just wanted to know if people were using rb30 head gaskets and if they can handle boost very well,
If thats no the best idea, where do you guys get your rb25det head gaskets from?

Reason i ask is because i've got a spare rb30e head gasket spare which i got from autobarn a while

Be more specific man! How much boost? Im using an rb30 gasket. Be aware a 25 gasket will only barely seal around a water gallery.

Hey,

Sorry guys, looking for 300rwkw or just under with around 15-18 psi, on e85, just wondering the tolerance of the rb30 head gaskets bare in mind the one I have isn't a genuine Nissan, it's an autobarn replacement

Mine is making 305rwkw on 98 with an acl monotorque gasket, no worries. I cant really see how a nissan gasket would be much better.

Where did you buy yours from? The gasket I got was only $50 so not sure how the quality is.

[Ben C34]

from spint auto in sa. was around 50 from memory.

How much boost are you running and on what turbo? Also how long has it been running for? They're around $80 for the monotorqe so it's below my budget which is always a good thing

running 20psi for only a few months. Have used one on my old vl turbo for years no drama, was making 280 kw. I can't see how a genuine head gasket can be much better than the acl. On the other hand genuine plenum, exhaust, turbo etc gaskets are heaps better than aftermarket.

I will also add that to be sure when using an mls head gasket you really should have the block face cleaned up, as the gaskets have hardly any room for error, and as I have left my bottom end untouched, I decided on a fibre gasket. Also I have run 9 passes at the drags and on first pass the was audible detonation that wasn't apparent on dyno, and I ignored it for the run and that didn't kill it!
