use the hi octane exchange sump. way better than a puny 800ml extra. ive seen bearings spin on gtrs wityh the extension. simply not enough oil.

the sump i made holds around 8.5 litres to the high mark on the stick. no surge at all as yat.

you can't use both. but for me unless you have a high volume oil pump (like tomei, trust etc) I would use the baffles.

simply because to fit the extension your sump needs to be cut in half and I have seen some welded on extensions that were done pretty poorly. and it's very important that the pick-up is sitting at the right depth inside the sump. also they hang quite low, it shouldn't be a problem, but if for instance you spun off the track backawards over a ripple strip (happend to me!) it would be in danger of getting collected. plus the extra capacity adds a lot of $$ to your oil change if you are using oil like motul chrono (which you should be).

so I reckon unless you really need extra capacity, just use the tomei baffles.

...also they hang quite low, it shouldn't be a problem, but if for instance you spun off the track backawards over a ripple strip (happend to me!) it would be in danger of getting collected.....

That's what worries me about the extensions.

well...i've had both on my race car and have seen some minor surge using the tomei style baffles - never had any sign of trouble with the trust extended sump.

but keep in mind this is on excellent tyres with great traction, right on the limit - I don't think most cars would see any difference.

re clearance I've run the extended sump on plenty of tracks including some offs and not hit it......but thats not to say it could never happen - the trust sump definately hangs lower than the subframe

Thanks for that, I do intend to run the car at the track so good to hear from someone who has tried both in those conditions

I'd say that has more to do with the build and not overfilling than not enough in an extended sump.

well I'm convinced. both dave and duncan I know have thought about this a lot. so I'd go with their idea. especially if you are using a nismo oil pump (not nissan N1, but actual nismo pump) as they flow a fair bit more oil than a stock pump at any given pressure.

    • Thanks both. All good advice. Reminds me of drilling through stone wall for drainage pipe 😬 I'll let you know how I get on if I still have use of my hands afterwards 😅
    • Finally got shipping number for the intake and throttle body, shipped by UPS, so "should" be in my hands sometime next week, fingers fracking crossed
    • I'm so far behind in the jobs I have to do at both work and home (including car) that I have become immortal. There's simply no way that I can die now.
    • Each to their own I guess  Me, I put just as much time into cleaning inside of the cars as I do on the outside As for getting wet, it is really no different than steam cleaning the carpets at home, apart from the cars carpet dries alot faster than the house, again, I only do it in the hotter months and leave the car opened up for a few hours As I only do it yearly, it is just before I do the diff and gearbox service, so I clean the carpets, then it's up on stands, wheels off, service, clean the undercarriage,  grease the bushings and do a nut and bolt check on everything  Disclaimer: I typically had all the time in the world to kill when I was working 🤣, so spending a full day or 2 cleaning, serving and "looking at stuff" was,  easily achievable, and a fun mental therapy day As for time to kill, I retired last Wednesday, so apart from my physical training, my days are filled with lots of random jobs around the house and garden...."Idle hands are the Devils something something" I am also buying a new house sooner rather than later, I'm actually looking at a potential property tomorrow, I'm looking forward to getting a car hoist as I'm starting to get to old to crawl around under a car, I can only imagine all the undercarriage cleaning and looking at stuff when that gets set up
    • Yeah, I'm not interested in wetting the carpets, and I don't care about brown dirt/dust that lives deep in the pile or underneath. It's not like I crawl around on them in my birthday suit or eat dropped food off them (because there is never any open food in my car). The seats are alcantara (cheap Chinese imitation alcantara, to be sure!) with barely 1" of foam pad behind the surface. That's not getting wet either. Any car that I would be happy to get the interior wet, I would not care to put the effort into.
