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.

stock undress 2nd hand motor $700

nistune what $500 ish

kando or highflow 2nd hand $600ish

highflow stock injectors $500ish

coilovers $500 2nd hand

2nd hand z32 $150

2nd hand fixed back seat $300

steering lock spacers $10

weld or shim diff $ buggar all

do that with the 3k

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.

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
