My Rb25 Top End Rebuild

[Stargate]

Just though I would post up what I've been doing to my 33liner for the past few months.

Backstory:

I was driving to work one morning and noticed that my oil pressure was about half of what it normally is. I drove it to my workshop and attempted to diagnose the problem but to no avail. I then decided to speak to my engine builder (who is currently in the process of building me a 26/30) and his first peice of advice was to rip the head off. After a few hours of ummmung and arhhhing, I spent the 3 hours it takes to get the stupid inlet manifold off and noticed that the head bolts at both ends of the motor were loose. Once I had pulled the head off, I also noticed that cylinders 1 and 6 were very oily. Valves on cylinders 3-6 were white.

What I'm Doing:

I got the head machined, vacuum and pressure checked and replaced the valve stem seals. Replaced head bolts with ARP Studs and a Cometic Head Gasket. I also decided that this would be a perfect time to upgrade to aftermarket manifolds, external gate, fuel system, cooler, retune ect. Hoping for 360rwhp with stock bottom end.

Future Engine Work:

I really would like to get an oil relocation kit and cooler. Its gonna be a prick to change the oil filter now that the big arse manifold is in the way. I will also get a BOV installed sometime down the track.

Ill keep this thread updated as I go. Ill post HP / torque figures when I get them.

I'm happy to answer any questions anyone might be interested enough to ask.
