Hey guys, i just replaced the headgasket in my 26, done a clean/flowtest on injectors, new waterpump timing belt and bearings all replaced, new sparks, and all gaskets on head have been replaced....

Now i need to know whats the best way to run it it, and what oils to use and for how long a duration before using the good stuff?

Also is it a good idea to re-torque the head after around 1000kms to make sure they havent gone out of wack slightly?

Thanks in advice

make sure you DO NOT USE COOLANT when you are first running the engine. let it warm up and drive it and get it all up to operating condition b4 you put coolant in. if you use coolant , the coolant soaks between the head gasket block and head and as it will dry up and have sealing issues later on. other then that drive as normal..

After you have driven the car for about a week or so then you drain the water and replace with coolant . all will be good

I believe GTST is 4.5, GTR is 4.7 and N1 is 5.1L

I wouldnt try the no coolant trick, alloy head is far too sensitive for that. Just dont drive it too hard for the first few klms so oil builds up on the new seals

      Yes, but 2 things of the top of my head, 1. Legalities of nitrous on a street car. 2. No chop chop. I fully understand that there's much cheaper ways to make power, and whilst a wet 50 shot is fairly cheap to install, bottle fills are expensive, and bottles always need to be refilled, and nitrous also has its own inherent issues with reliability, and tuning, from my experience of others using nitrous, it doesn't take alot to lunch a engine real quick if something goes slightly wrong when spraying, if I wanted a big chunk of additional powers, a spooly boy would make alot more sense, disregarding the additional engineering, supporting mods and other logistical issues of sticking a spooly boy on a car that came naturally aspirated from factory  In the end I'm not racing for sheep stations, and I don't really care if people make more power, or are faster than me, or spend less, or more than me, the only thing the car needs to do is drive around and make me smile, which it is doing now Really, I just want a shiny new intake to look at when I'm cleaning the engine bay, and of course, some more induction doorts, and maybe even that 5kw for that elusive 200hp cherry on top that I might get If the FAB9 intake plenum, TB and air filter box thing doesn't eventuate for whatever reason, Plasmaman do one, not as fancy looking, and a fair chunk of more cash is required when including the TB and other bits and pieces that are required to install it, but, it is another option that is available to me if FAB9 one does fall down (but I really, really.....really, want the FAB9 one though) TL;DR. You want what you want

      Ceramic turbine damage to engine - what did yours do?

      By zique · Posted

      Been so long since I have been here,seeing SDU is dead. I had that problem on my gtr in 2006 but luckily there was no engine damage,it was inspected by Hytech Engines,race bearings and extended crank collar put in and that was about it. Hopefully yours is sorted now.
