I have said it many times before...do not even contemplate taking your GTR onto the track if it doesn't have a proper baffle in it. People in this thread have punched a hole in their blocks or spun bearings.

It is not a very expensive thing to do but will save your engine. If you want to do a track day in your GTR, please do up your sump first. Oil cooler is necessary, but will not stop your oil from surging.

Yes, The R won't be seeing any real action till it has new sump with baffles, large capacity oil pump, oil cooler, bigger radiator, oil restrictors, enlarged oil return galleries and catch-can. So by about the year 2010 I think I should be ready.

Apparently the engine has to come out to take the sump off. Does anyone know what it is worth to fit baffles??

To baffle your sump i think it costs around 200-300 done by the mechanic i use. You might find someone to do it for cheaper.

My Trust sump set up was cheap, but that's because I'm a dodgy Asian. I did not do the sump myself as I do not have an engine hoist nor do I have an angle grinder and a welder. Alternatively, you can buy a ready made JUN sump (not the parts to baffle the sump) for about 3 times what I paid for the Trust item.

I have said it many times, engine revs or how many laps are not important. How hard you turn is the important factor. QR has 3 right hand turns alone after the main straight, consider how much the oil would have moved to the left. Then think of the starved engine being revved to pull the car through turn 3 and bang you have a hole in your block.

So far, my mechanic has handed out accurate and invaluable advice to me, although it doesn't come cheap, although his advice regarding the sump was:

"Some people have gotten away without a sump for a couple of track days, but it's a $10k risk you are taking. If you're unlucky, your engine will blow by turn 2."

I don't know where people got the impression that GTRs are track ready from factory. They're far from it. They're a road going homologation of a race car, except the N1s or the special edition GTRs.

You have no idea how many times I thought I have prepared my car for the track only to be told this this this needs to be changed first. Not a cheap hobby nor car to choose for the track.

On a side note, Sydneykid has explained why the GTRs experience higher oil temps, i.e. 2 turbos and mainly because the front diff runs through the sump.

Hey rb26dett, who is your mechanic? $200-300 sounds bloody cheap. I NEED to get mine done ASAP and am currently trying to get some pricing.

Thanks

      R33 GTST Sh*tbox to Polished T*rd

      By Yeetus · Posted

      Gday Thought it was about time I started a build thread! As expected this project has snowballed into a huge financial liability, but unless you’re strong willed and responsible, it’s not a surprise. Background -  My first turbo car was an R32 GTS-4, got my full license and then totalled my Au Falcon a week later, so while trying to sell my RMZ450 dirtbike to buy another car a bloke offered to swap the R32 which at the time I felt like I was ripped off but looking back and seeing prices of those now ($40kish) it was a good deal, I didn’t know enough about these cars to appreciate what I had so sold it before the RB20 blew up. Between here and there, out of 12 cars I’ve owned the note worthy ones are a V8 Lexus SC400 (soarer), a couple of XR6 Turbos and my beloved S15 which I had for about 3 years, picked it up for $12500, repairable write off but she was fine, gun metal grey/pewter and bone stock/unmolested until I got my hands on it. Ended up spending about the value of the car and 280kw, 2 demerit points by the time I got defected and sold it for $14500 (also $40kish in today’s market, rip) Fast forward to the present day, I’m in a much better position financially and daily an MQ Triton (great cars, pipe down Ranger Bois), I cruised marketplace and car sales for a few months looking for another R32, the best deal I could find was an absolute rust bucket half finished project for $12000, until this R33 popped up in Port Macquarie for $18k - unregistered and barely running but decent shape, kept an eye on it for a few weeks and the price steadily dropped, $16k then $15k then $14k, that was the point where I was like shit someone’s gonna snatch this up! It was owned by a young bloke who had big plans but him and his missus just had a baby so smartest move financially for them but big gain for me. So 2 days later I’m towing a car trailer to pick this thing up. Roughly 2 weeks and $3500 later I’m cruising around Newcastle in my beat up R33 all smiles and dose noises! It only needed some basic shit to get it going, coil packs and air flow meter, electrical stuff and all fluids changed, 158k kms and running pretty good, nice smooth engine after oil and coolant flush - when I say coolant I mean it had been filled up with tap water, every gallery and heater element was filled with rust, 8-9 flushes later and still had brown liquid coming out but she’ll be right. The car was painted R34 Bayside Blue at some point but whether it was a cheap job or just not looked after is anyone’s guess, clear coat flaking like sausage roll.  Was rethinking my choices and contemplating life, had it up for sale for $22k - still cheaper than any registered R33 but got little interest, next minute I had an opportunity at work - 6 months overseas for good money, so that was a no brainer, fast forward again and here we are with a 50% finished project. Current Mods - 200ish KW according to butt dyno Was tuned with Apexi PowerFC EBC (old school Greddy Profec)  Stock turbo (more shaft play than a Tinder date gone right) 3inch turbo back Varex muffler  Aftermarket injectors of mystery size, Power FC showed 36% duty cycle at full boost so not behd good size Someone had good intentions but stuck with the stock R33 MAF so we had misfires at 6000rpm due to the MAF hitting 5.2V So far I’ve redone the entire interior with carpet form Car Mats Direct, new Seats and steering wheel from Autotechnica, also sound system by Autobarn (mainly Kicker) Also MCA pro comfort coil overs - Hands down best purchase yet, worlds of improvement over the tired 30yrold shocks Goals - 450kw/600hp on flex tune New paint job - Midnight Purple 2 Engine is at the shop getting rebuilt with forged rods a pistons, new valves and springs, ATI Harmonic balancer, Aeroflow 7.5L sump, rear head drain and oil restrictors as per oil control thread* and cam covers modded for larger breathers, other stuff I can’t recall of the top of my head Parts purchased and to be installed once the engine is done -  Engine loom from Wiring Specialties including these options: Haltech Nexus S3 R35 Coil pack conversion  PRP Dual Trigger kit Fan controller  Other Parts -  262 Kelford Cams Turbo - Hypergear ATR43SS3-ProS with T51R mod (whistly boi) 6 boost manifold (high mount) 50mm Turbosmart Pro gate (plumbed back for legal reasons) HKS Super Turbo Exhaust with High Flow Cat Custom 3.5inch dump and front pipe 1500cc Bosch injectors  Fuel Pump walbro 525 Haltech MAP and IAT sensors Haltech Flex Sensor Fenix Radiator with dual thermo fans LS1 Alternator Kit Oil Filter Relocation from EFI solutions and Cooling pro oil cooler Many other things sitting in my garage waiting for that engine to come back. Progress pics to follow -

      Losses have to be less with DC coupling. Provided the battery inverter has decent MPP tracking ability - which really shouldn't be a problem. It's not 2005 any more.

      Hi, Will the R33 GTR rear brake backing plates fit a GTST? I'm struggling to find GTST ones but can find new GTR ones.   Thanks.

      Some more close up pics now that I’m back to working on the car, the loop pile is nice but again haven’t compared it to the other types in person, it’s hard to tell from the pics on the website. View of the hemming on the edges too, it comes in 2 pieces - front and back, honestly very happy with it for anyone on the fence.  Also attached my previous pics from further up as it didn’t let me post them directly before. (Nothing worse than photo bucket pics that aren’t hosted anymore years later)
