Hi Nick, As per everyone else I was sorry to hear and hope she goes back together with no dramas...and hey she'll come back stronger than ever ;)

I recommend going something like an N1 oil pump (I also believe the Jun oil pump is a top item but $$) and the rest of the mods you suggested from the SK thread. I too would baffle the sump at the very least.....items that fit to your existing sump without mods are fairly cheap and is good insurance. Definitely loose the Penrite IMO...I have not heard good things about it during my time on SAU....benno uses and recommends Castrol Edge 10W60 and this oil has been good enough for me over the past 3/4 years. Overfilling the oil is a must do although the extra capacity of the cooler will help.

You "freely say" alot of things Ash; many of which alot of people disagree with :nyaanyaa:

Yep, and true to my word i run the setups based on that, and they are all fine.

Everyone said i wouldnt make anywhere near what i did on stock cams.

I did that easy enough.

And i'll also run a 300+rwkw circuit car with a stock sump/cams ;)

People tend to disagree because they blindly accept what they are told by mechanics without actually looking into things

Chris ran 1.21's around sandown with RE55's on a stock RB26 engine/sump.... 250rwkw.... no issues with spun bearings, so there was no Benno Trickery there.

I've run 1.22's around sandown with RE55's and a stock sump (as far as i know anyway) But there is other Racepace trickery with the oil in my engine, but i think the sump is still stock. I don't think the sump is the issue, but gtst could be different to GTR... It wouldn't hurt to put a baffled sump in, but don't assume its needed....

I'm with Troy... Penrite 15w? I don't know if it was the oil, but i defiantly recommend the Castrol Edge Formula R 10w-60 stuff... that's what most of us run....

yeah the Penrite isn't my choice but I get the servicing for free so wasn't arguing... I really didn't think I would have this problem so I must admit I was a bit slack... just have to do things the right way, a little bit of work on the motor to control the oil better, using more oil and better oil I reckon I should be right... if I do everything else I don't think the sump is needed... I'm going to get a couple more quotes though, it will be going to a specialist workshop this time

interesting email I just received from Hi Octane when I inquired about oil restrictors for the RB25

"Under no circumstances should you restrict oil to the RB25 head. The RB25 runs hydraulic lifters and needs a lot more oil supply or will result in failure."

Reading what Nick has said I don't think the lack of baffled sump is to blame.....however not over filling the car + the fact it doesn't have a baffled sump cannot be good. First and foremost Benno recommends that you over fill the car with oil...once thats taken care of any other mod like the baffles etc etc is extra insurance.

Using your standard Penrite HPR stuff, 15W I think...
15W what? IIRC, Penrite is 15W40, maybe. 15W60 (and the '60' is the critical number) seems to be what is required if you are intent on caning the engine.
Using your standard Penrite HPR stuff, 15W I think... oil was 4,000km old and really should have been changed (had done a DECA on that oil)... oil temp was okay, in the high 80's low 90's at the time... no misses car was running great, I was coming out of the 3rd last corner, going under the bridge, high rpms in 3rd gear and it just let go

yep Ash seriously considering that option... I really don't want to have to take it out again

Really bad news... sorry to hear.

eeek penrite... cricuit sprints is harsh on oil and drifting is even harsher... both penrite and Castrol both breakdown way to quickly in harsh conditions.. we spent a lot of time testing differrent oils last and early this year and group V's are really the only way to go. You should see castrol edge after one drift day.... it comes out like thin as like metho or water and it noticeably traumatised :D... drop out 300v or redline 10w-40 and it is like new after 3 events even mobil 1 seemed to fair way better :D redline actually told us to run the same sump all year but im old school and that scares me, we now change it every 2nd event to be sure.

i look at oil as insurance, pretty cheap insurance.

But are we sure that the rebuilt GTRs in Vic are usign completely std sumps?

I know a few of us no longer have standard sumps. The engine was out so may as well play it safe. It's a Benno built 8L. I'm pretty sure the same one is on Scotsmans, Jacks and Aarons.

imo a litre over full is way too much.keep in mind that to much oil and you can start to blow seals.

when i am changing the oil i allways empty whats left in the oil cooler out and refill the engine with 5L of oil then all it takes is another 100-200ml extra oil to fill up the oil cooler.all up,it fills everything and some. my 19row oil cooler in reality only holds a 100-200ml at a guess,if that.

because my car is pretty much exactly the same as yours is bar the azenis and i run 13psi all day every day.for ages and ages it has been this way..and see's pretty much the same sort of track abuse throughout the year id say that you should go the oil cooler route.

Castrol Edge sport 10w-60 is gold i use it every time.

ah yeah ive seen these killer 8l sumps down at access performance in vermont... killer items.

i know ppl with gtst that have nearly 300rwkw and still have standard bearings.. they are not really needed but u might as well do them while everything is out...

Read what i am typing buddy.............

It's NOT about the power, it's got to do with my applications and high reving.

Not hear buddy :)

I have also done my research and act on various advise from various people, including those for interstate. If i just listened to my mechanic i would have never fitted the r34 hi-hlow, which was a great item and my current build would have a 800hp turbo running NOS :(

Yes one can make the power on a standard engine, using a bigger turbo or running more boost, etc. Cams have been a well proven benifit, and even Ben wouldn't disagree.

Thanks Snowy.

I never said a sump is a must, just stated that it is good insurance. I always side on the side of caution, so if some consider my enhancements as overkill, well so be it :( .

What brand of oil are Group V's or 300V?

Have you tested Fuchs GTO? (not sure if i spelt it correctly)

    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
