Need more info to be able to give you a better answer but...

I have seen stock RB25DET's push over 300kw at the wheels, but there are so many variables that you cant account for when extracting big power from an internally stock motor...

Your mate might get a solid run for a while with big power, or he might have to re-build it after it blows a hole in a piston... It depends on how healthy the engine is to start with.

Most of his reliability will come from a really good tune (assuming he is using high quality parts and lubricants aswell).

engine strength is not an issue. its tune quality and how close to the edge of detonation you want to run.

any engine, even a fully built engine with thousands spent will fail under prolonged detonation or preignition.

theres stock internalled engines pushing 300, 400, 500kw reliably

it all comes down to the tune and the quality of your supporting mods to ensure that the measured fuel is delivered and adequate cooling/lubrication is provided.

Yeh, to be on the safe side, I would suggest injectors, fuel reg and probly invest in a good fuel filtration system lol. Judging by the mods he wants a bit of power from it. There is plenty of places to get tunes here in Canberra. I believe ed from Autotech is a Haltech Rep, so probly see him. Or ESP I reckon would know their way around a Haltech and Trojan are Skyline specialists...

has a fuel reg and is getting a new fuel pump (something bigger and better then a gtr one) and some injectors. cheers stu and the tune is going to be done in nsw from someone i have never heard about lol mean while he then is going to take it to a place in sydney.

    • The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.
    • When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.
    • Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.
    • This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
    • Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
