Hi y'all

My bro finally joined the skyline club!

It's an '95 R33 series 1

He wants a drift car out of it and has to rebuild it cos piston rings are gone

My question is what would you suggest he does whilst the engine is apart? He's a mechanic and all the work will be done at home... He wants to spend about $2-3K

The front mount has been installed but that's about it at this stage, pretty stock...

Thanks heaps

Forged pistons, RB26 or just balance and shot peen stock rods, Nissan or ACL bearings, Metal head gasket, N1 oil pump with Billet gears if you dont want to go a good oil pump, Head drain/return, IF he's building a dedicated drift car id go a larger baffled sump ASR or Hi Energy.

What power figures is he after also how reliable does he want the setup to be?

1> Don't drift it on the stock turbo. He will want more power, he will turn the boost up, the turbo will shit itself, he will be unhappy.

2> Don't drift it on the standard ECU. He will want more power, he will turn the boost up. The ECU will crack the shits, he will be unhappy.

That's already more than $3k right there. Double the budget, then double it again.

People are out there drifting with RB20e motors in there cars, so a standard RB25DET should be fine. More power is great, but I guess it also shows that handling setup can and is just as important as power. By all means though get some more if he can because, why not!!!!!

Head studs, oil pump collar, oil pump, oil restrictor in head and enlarge block drains.

Extended/baffled sump with an oil cooler. Then you should be set.

Stocker 25's go great. Dont worry about power yet. Get the suspension gear done (diff,castor,camber,coilovers,rack spacers) then worry about hp.

Basically. Get the cooling spot on, Oil control and reliability spot on, Suspension and steering spot on then when you can confidently drive it in the red all day long (7,000rpm) and pull big entrys.. then you put more power into it. Your coight will pucker when you're 3rd pinned about to initiate your entry at winton before the last s bends. Thats without much power.

In terms of the factory RB25DET tune, is it considered "safe" for drifting/track work/in general? Obviously not maximized for power or apparently ralative fuel economy but aside from that.

Stock tune with the engine in stock form and it will do fine. From memory i think it runs a little rich so not a bad thing, correct me if i'm wrong.

I drifted mine for over a year, factory tune with just a front mount and turbo back.

I'd never go to the track with a stock ecu on a RB25DET thats been boosted. I melted a couple pistons on the street with my old RB25 running 12psi. Put in an unopened engine with an ecu and a good tune been making 300+kw for around 6 years and ringed the absolute neck of the RB and it hasnt even had a missfire.

A vehicles tune is a make or break sort of thing.

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that

      Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything

      What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day   Highway gets as low as 10l/100km on my end so I'm not as worried about it being a mechanical issue. More likely just the tune on the haltech.

      RH9 R32 GTR Build Thread

      By OST Micah · Posted

      While I was waiting for the new parts to come in for the charge pipe and radiator I decided to do some turbo modification. The drive pressure (exhaust backpressure) was a lot higher that I thought it should be. For 32lbs of boost drive was 55lbs. The turbine housing is a 1.10AR and my turbo builder has suggested to go to a 1.25AR. To test if a larger AR would do anything to reduce drive pressure AND not spend any money I decided to hog out the divider in my current housing. I removed it from the inlet and the whole way through the housing.  After reassembly and testing it doesn't look like this modification did anything for reducing drive pressure or requiring more fuel (making more power). Oh well, it was worth a shot. We'll get some data at the track if it makes it past the 60ft. I also machined a $7 shift knob off Amazon to fit my Stillway shifter since I didn't like the Stillway shift knob. Next on the list was the radiator replacement and fabrication of a new intercooler tube that had no silicon coupler. No pictures of this - I was short on time each night after work to get this done and didn't stop to take pictures.  Next was to get the clutch disks out and replaced. Previously when installing the dogbox I had ordered a set of the same sintered iron disks I had been running because I switched to the 26-spline input shaft. I thought it was odd that they didn't have any markings or brand name on them like all my old disks had but installed them anyway. At the track I could not get the clutch to lock up using my normal strategies. After two track nights I reached out to the clutch manufacturer and ask their thoughts. They said they had to switch the material out because they were having trouble getting the original material and that this new material would not take to being slipped very well.  So out with the first set of 26-spline disks and in with the correct material 26-spline disks. While I had the trans out I added an inspection/service hole. I've wanted one of these for a while. Now I can have a look at things and change the front cover shimming when needed (clutch wear). I hustled and got the clutch change done in a few hours on a Saturday. Hopped in the car and drove home. On the way home I did a 1-3 pull. When shifting from 2nd to 3rd the core plug in the back of the cylinder head popped out and dumped all the coolant. Thankfully I was only 30 seconds from home and coasted it there. Datalog showed nothing unusual and 2.5psi of coolant pressure. That plug has been in there since 1992 but I guess it worked its way out. Pulled the trans AGAIN and replaced the plug, JB welded it in, and made a brace. Also deleted the head drain I had added in during the bearing issue fiasco.  I am currently changing my boost control plumbing to make it cleaner. After that is done I'll make another attempt at getting past the 60.
