Hi all, just a little info about me :)

Name's Blake and Im stepping into the JDM world. I have been primarily focused on the ford 4L inline six, and while its a great platform for easy reliable power it was inevitable that the high revving nature of the Jap inline 6s would eventually take hold on me.

My daily driver is a 400rwkw 6sp auto xr6turbo.

My project is a turbo Ef falcon 5sp.

so now onto why I am here, I recently purchased an r34 GT4 from a mate, the car has been kitted out with anything retrievable from his wrecked 33 gtr.

-RB26, forged internals, nitto gaskets etc etc

not sure about oil pump but it does have an enlaged oil drain in the head.

HKS 264 cams

HKS cam gears

HKS GTSS twins

3inch catback with stock dumps (got dumps on the way)

Trust oil cooler

Fuel system:

Sard billet fuel rail

Turbosmart adj reg

sard 1000cc injectors

twin braided fuel pressure lines and single oversize return

twin intank walbro pumps with relays

Haltech platinum pro with EFLEX e85 sensor.

r33 gtr brembos

Koya r-1 245-30-19 fronts and 275-30-19 rears

r34 gtr rear wing

Basically the car got defected, my mate spent 8grand on the fuel system, ecu etc getting it all legit and passed emissions.

when it was time for the e85 power tune the tuner said he heard a noise and was worried about a spun bearing.

so I offered my mate 6k for the car and he regretfully said yes.

the car was fine to drive around with no rod knock.

however, on cold start only while the oil pressure light was one you would hear a series (maybe one seconds worth) of knocks

factory oil pressure guage seems to be semi retrarded so I fitted a mechanical autometer guage, 60psi at 4k cold but after the oil heated up the pressure was only 10psi at idle. I can hear a very slight knock so I have decided to pull the motor to avoid a potential for legs leaving the bed etc

Now I have done a fair amount of research on oil systems for the rb26. That doesn't make me an expert so I would like to list me plans and see what you all think.

Billet N1 pump $350

n1 housing $350??

ACL race series bearings

now I am unsure of whether It is really necessary to go for an extended sump or just the tomei baffles??

I plan on doing hill climbs, track days etc. the car wont be stripped out.

I already have the Oil drain in the head enlaged, I couldn't find receipts for which pump went in when it was rebuilt (3000km ago)

sump will be overfilled for track work. and if I can get away with only the baffles I will be much happier keeping the extra grand for other things

Im going to have a crack at removing the motor myself, looks like a PITA, rebuild it myself and go have fun :)post-117959-0-92601700-1376206934_thumb.jpgpost-117959-0-42270900-1376206948_thumb.jpgpost-117959-0-76854400-1376206953_thumb.jpgpost-117959-0-72476100-1376206965_thumb.jpg

update,

Got my N1 pump from the sates, replaced the N1 gears with a billet set.

Managed to get my hands on a modified turbo outlet pipe, hopefully the baffles give me a nice little bit of response.

I'm hoping to get the most out of my little GTSS turbos.

Plans while the motor is out:

Fix the coolant passages in the head.

,Bearings and does anyone recommend further crank balancing? and how necessary is a nice harmonic balancer?

looking to limit revs to 8500rpm, cams are hks 264/8.7s

most other things should be pretty good since its such a new motor (touch wood)

Tomei sump baffles.

Im assuming that r32,33 and 34 exhausts are fairly similar and would fit either car? have a 3inch but am looking for a 3.5inch if anyone has one nearby (Newcastle)

Haha that's alright mate :) Ill definitely post some more pics up when I get a chance! I'm thinking of getting some ROTA grids for it and selling the koyas. Not sure what the max width I could go on the front wheels would be. But ill be happy with getting rid of these wheels and dropping my coilovers to a cop friendly but clean height :)

Yeah I know Koyas are better design but I'm not a big fan of 19s on my car. I'd rather a nice set of 18x9 ROTAs . They look good to me and I won't be jumpin ripple strips every day haha. It's mostly for looks. I might go with painting my 33GTR wheels black to start with

Update,

picked up a few buts and pieces.

Tomei Sump baffles.

N1 oil pump housing with Billet gearset.

HKS 2540s with split dump pipes,

HKS 3.5in legal exhaust, (will be fitting varex muffler after I pass noise test.

ARC twin entry cooler.

.

engine was a bit of a struggle as im not the smallest bloke and found access difficult. starter motor wtf???

looking for around 400awkw or so on e85 but not fussed if Its less :)

time to change bearings and check tolerances :) then tune time!

    • 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).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
