Thanks for the tip Stony, Nice times in your sig too man. Very impressive Z.

One of the best descriptive/informative RB build I've read to date. Maybe because you didn't "hide" really anything. Awesome read I just spent the last 1.5 hrs reading through this 2 page thread and it was great! What are you using the seal the rear vent you have on that 26 head? Is there a recess cut for an o-ring back there? As for the quench pad removal. I'm currently starting a build up of an e85 67mm build. Looking to make mid 6's through it to the ground. Car will be mainly street driven/highway car, with the occasional journey to the drag strip. My question (s) for you here is from your experience how much additional timing was a rb26 head able to take with the pads removed, keeping all other variables the same (boost, fuel)? What pistons did you have made, or did you use to bring the compression ratio up? Most say there will be a loss in mid range, and efficiency slightly but how much exactly? What it comes down to is I'm questioning removing the pads or leaving them. I burnt up two rb25 cylinder heads really bad, and the quench area pretty much took all the heat, with no signs of pre-det showing on the plugs, when obviously inside it was blowing itself to bits. This issue was more caused by a ECU/CAS related problem in picking up the cas single properly. (timing was really low values like 15-16 from threshold on at 12-13 psi boost, engine was obviously seeing a lot higher timing that it was supposed to on 93 oct) Any bit of information you can provide would be awesome, I really want a well running mid-higher HP RB to run correctly and for a while, its been a few year process of blowing cash, and engines, while finding the issue far too late.. -Cory

Very nice Z man! It looks stunning!

Still looking.

Looking for a complete Rb26 head in good condition along with intake side items. (plenum, itb's and hardware) email: shockster0429@yahoo.com if you have any. -Cory
