Hmm... I have almost got all the parts I need for my build. One thing that ive been searching for ages for is a head gasket. What is everyone's opinion on high performance gaskets vs standard OEM ones? Anyone running big power with standard ones?

I want to save some $$$ but if its crucial to buy a Cometic or something ill just do that instead.

Most of the time head gaskets let go because of detonation.. so by having that as the weakest link then it could potentially save the piston/rings which would be next in line if something went wrong.

Kind of like running street tyres vs slicks at the track. The street tyres are the fusible link, they will only take so much force before they just start baking. If you run slicks and then all of a sudden your shafts/diff/clutch need to be able to take a whole lot more force otherwise they go – if that makes sense.

With that said, I bought a Cometic 3 layer

I am hoping for around 450 - 500rwhp. I sent an email to spool imports regarding the shipping price for a cometic gasket. Prices on Ebay seem a little expensive and plus I dont know if they are genuine or not.

I bought a cometic mls head gasket from Fabre Australia in Lakemba. I paid $300 for it but they were the only supplier in Australia to have a 86mm cylinder bore head gasket with 51thou thickness.

I just bought the same one from Spool Imports for $250 including shipping :)

use the stocker. its fine for power even higher than that.

I used a rb26 oem one the first time, now im using a cometic metal multi layer. I have to say I liked the stocker better the difference in quench was noticable. it really depends on how much boost you plan to run and power figure.. for your goal.. it wont matter unless, as others have said, you want to save some $$$ if you need to pull the head off

Can you please explain what you mean by the "difference in the quench was noticeable"?

Providing you're using the same thickness gaskets, quench measurements should not be changed. You must be good if you can feel a quench difference!

I am making that sort of power on a stock head gasket

      Never ending fuel pump drama

      By cabramatta · Posted

      Might piggy back off this thread since there's been a good discussion about PWM.   I purchased a Walbro 460 F90000267 and have been looking into PWM to understand it. It was purchased more of a future proof as my original OEM fuel pump died (r33 below 200kw) and figured I'd just upgrade it to this. That's when it hit me that a pump this big can cause more dramas with such high amperage draw and heating of the fuel pump being on 100% all the time in such a mild setup.   I have a Nexus R3 and slowly collecting power mods but I was looking into the PWM feature on the NSP software:   Then looking at the graph from the fuel pump:     Am I safe to assume reducing duty cycle to 50% for example would make the pump run like a 230/lph ? Where does the PWM come in all of this ?   I've gone down the rabbit hole of PWM fuel pumps and it seems there are many differing opinions on how to go about it 😅

      Thank you, this will keep me busy for a bit.  I will update progression.

      That specific one would be an exchange part, meaning I'd have to send mine to them. Plus it looks like a non AWD sump, which won't work for me. There is one or two shops in my country that I can ask to do a sump extension job and it'd most likely end up being cheaper than sending mine to AUS or NZ and getting one back, and quicker too.

      Rear turbo is leaky, most likely at the oil drain. From what I could see with my boroscope it seemed to have seeped out at the very top of that return hose. Is it possible that the oil climbs up that hose to then leak out? Yup, coolant leak on the hot side of the engine, only noticed after seeing clear rusty residue in the block right from the turbo oil feed downwards to the pan, and red droplets hanging from the pan. No clear sign yet from where it comes, and most of the lines there are hardlines right? Last year, seeing those red drops, I thought it was power steering, will be glad if that is not leaky at least. Another leaking hose I found by chance is the lower of the two heater core hoses coming from the firewall to the back of the head. That one is not too bad to get to if I have to replace.

      I think for response I'm already kind of out there no? he -5s are not the best pick for that as the Internet tells me. Maybe I should switch to -7s while I still can? Though that almost definitely warrants an engine pull along with the other issues I have.
