Unless you are drag racing it constantly there Is no real need to go cement fill it. I am running a N1 block with custom 86mm CP Pistons to gain maximum bore thickness with stock girdle and the engine makes close to 900kw. It has had plenty thrashings still holding together quite nicely.

Cheers fellas! Good feedback! Seems like to the bottom of the welch plugs doesnt cause any problems so I will run with that.

XRATED - Ive already got a little 240v vibrating motor ready to bolt on my bench :)

NUR33 - I would have liked to put an N1 block in it but have already spent the money on the stock one so just chasing a little bit more strength / reliability.

Cheers Simon.

Great minds think alike... I'm 1/2 way though the install of my DC ally electric pump today.

I'm going to leave the mechanical pump in for a few reasons.....

1. I can't be assed pulling the whole face of the enginge off to rmove the water pump.

2. The mech pump will provide redundancey if the electric pump fails for any reason.

3. The underdriven N1 pump has a reduced parasitic draw on the engine, especially if it's not having to draw coolant.

4. I want to keep the stock fan hub and shroud arrangement, but will be gong to a gtek fan and adapter. I know I can press the impellor off the water pump, but see points 1-3.

5. The DC controller offers a fan out put that I'll be using to controll a thermo fan on one of my oil coolers.

Cheers

Justin

    • The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.  
    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
    • I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋 
    • Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
    • So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around without a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.
