Just a quick question, has anyone used or had experience with the Supra cores on a Skyline. Im referring to the 7M-GTE version with the outlets on the same side. Handy for RB20 owners with both pipes on the same side :P

It seems to me like theyd be a pretty good size for an RB20DET, however ive heard about them being generally inefficent. I believe the measurements are about 500 x 280 x 75.

In terms of scope of development of my engine, im really only looking to run 0.8-0.9 bar safely... which at the moment is proving dangerous on the stock core (already broke 2 exhaust valves due to detonation and lunching a spark plug).

The future may hold an RB25DET, so im not too fussed about spending heaps on the 20.

should be fine but I dont think your cooler is the problem

check your timing it should be at 15 degrees or even the type for fuel you use shouuld be 98 not plp which is 95

your car might have an after market ecu tuned for high rom fuel or your fuel pump could be on the way out I would look at these area's

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel

      What should I do next to hold the head on

      When you pulled it off, there is no signs of blown head gasket? Is it possible you have some other issues going on? Possible cracked blocked? Or do you think it's straight up lifting the head? Did you check what the head was torqued to before pulling it down (To see if possibly they're stretching, or starting to break threads out etc)?
