cams will depends on turbos you choose, small responsive low mounts stay stock, or if you must Tomei type R cams

injectors, I would go ID1000, should be plenty for your goals even if you decide to go e85? much better then the old school denso types (think sard, hks, etc)

may aswell port the factory manifolds while they out

if your gonna do head work may aswell do cams and cam gears at the same time, and valve springs ? new shims.....something so simple as a freshen up can end up becoming a full all out rebuild lol

Thanks guys, I keep hearing about the ID1000cc Injectors, so looks like I will probably have to be added to the list of things for once the block is back in.

I think a lot will depend on what we find when we open it all up. The std cams vs small upgrade cams is still something I'm not 100% on but I should have a better picture once they are out.

.....something so simple as a freshen up can end up becoming a full all out rebuild lol

I'm sure a lot of people here know just how quickly it can all change. As I said above until like a week or two ago the engine wasn't even coming out haha and now I'm talking about rebuilding the head, new internals etc. lol :blink:

Engine out - rebuild.

I focused on fixing any oil issues.

1) Tomei pump (heard Nitto are good to)

2) Extended sump

3) Baffles

4) Restrictors

I have -5's. They have more lag than the stock turbos but not worried they are heaps of fun with 370kw atw.

Oiling issues aren't about oil supply. They are about blowby control and oil return.

Hey guys, Happy New Year to all!!

Sorry to revive an old thread but the engine is coming out in the next week or two and I am starting to finalise my order list to make sure parts start arriving in due time. On the whole Oil issue I am still confused slightly by what is required in upgrade my 90 model GTR factory oil pump and associated parts.

As mentioned above I was looking at getting (depending on Crank condition when removed) just a JUN Collar, N1 Oil Pump (p/no - 15010-24U01), Tomei Baffles and 1.5mm Oil Restrictor. I think this setup would work although I am 100% not sure if the JUN Collar will work with N1 Pump. Secondly I have looked into upgrading the std pump gears (Reimax) for a similar price but can't find out if I still require the Collar etc. and if it will actually give it the larger contact surface or if it is just stronger so less chance of cracking?

Can anyone help with what would EXACTLY be required to fit the upgrade gears to my pump and will that be as "strong" as the N1 Setup listed above? I am also looking at getting a New std Harmonic Balancer to be balanced with the Crank etc. but an mot sure if the std balancer will work with the upgrade collar and pump??

Thanks guys, any assistance will be greatly appreciated.

ENGINE IS OUT and everything has been stripped. FINALLY!!

Hey all, just thought I would give a bit of an update on where I am at with everything. During the last week we have finally pulled the engine and have stripped it completely down to just block with in a few days and so far there is no big surprises or big news. The only signs of wear etc. are on the Main Bearings (2 of them worn on one side more than the other so other then a line bore and standard refreshing required only) so it doesn't look like there is a lot to be too concerned about.

Decision has been made, with the help of the engine rebuilders, that we are going to do pretty much a full rebuild with hopefully reliability and useable street power the main focuses. So far the list for the block and internals are as follows -

- One-Size over Forged JE or CP Pistons - 86.5mm

- New Big End and Main Bearings (ACL or King)

- Check Crank for straightness and just Linish if OK

- Factory Rods with New ARP Rod Bolt

- New Harmonic Balancer

- Line Bore

- Cylinder Hone etc.

- Skim Head and Block

- New 1.2mm Nismo Head Gasket

- ARP Head Stud Kit

- Full Head Refresh - Re-Seat Valves, Seals etc.

- N1 Oil Pump with Crank Collar fix

- Complete Bottom End Balance

- All seals and Gaskets as well as New Belts, Factory Hoses etc.

The things I still haven't decided and would love some feedback on is -

- Porting of the Head while it is being overhauled. I have heard there isn't huge gains to be had and that it would cost around $700-$800 to do. I love the idea of having it done but unsure if worth it.

- Cams - I will definitely be doing the cams with adjustable gears with the head so they can shim them etc. but undecided on Type A, B or R?? I have been told that it would be best to also do the matching springs for these cams.

- Will mostly likely be running Garrett -9's or -7's with the hope of a fairly responsive street car with around 350kW - 380kW at the rears. Would -9's and -7's be capable with supporting mods of course of hitting the 350-380kW mark safely?

Can anyone provide any feedback on the above? I have my mind pretty set now but want to make sure this isn't something that will need to be done again anytime soon. but I am still unsure of a couple of little things. Engine Management, Fuel Injectors etc. will all be finalised once the block is back together at this stage as my brain is overloaded and I want to focus on one thing at a time.

Thanks guys, I will try and get some pics up when I figure out how to do it :unsure:

Hey everyone,

I know it has been a while now and not too sure how many people were actually following this thread in the first place but thought I would provide an update about this build and let you all know where we have ended up after all the research and feedback from you all.

Since the last post things have come along way and have changed and adjusted the whole way. Good news is we are now not too far from having everything here and ready to go back together. As a few people stated previously in this thread, I have made sure as much as possible that it will be done right the first time. So after a lot of time and obviously money this is where we currently stand.

ENGINE - CP Pistons (9:1), OEM Rods, OEM Crank, ACL Bearings (Main and Big End), APR Bolts and Studs, OEM Harmonic Balancer, N1 Oil Pump with Reimax Gears and Crank Collar, All Balanced, TOMEI Sump Baffles, Oil Gallery Restrictor, Checked and Cleared Oil Returns.

HEAD - A Bunch of Porting, Polishing and matching, Type B Cams, Type A Springs, Full Refresh of Valves/Guides etc., E85 Cam Baffles and Adj. Cam Gears.

MANIFOLDS, ACCESSORIES ETC - OEM Manifolds, Port Matched and Extrude Honed, Enlarged and polished ITB's (resealed and shaft re profiled), Nismo Gasket Kit (1.2mm Head Gasket), R34 Fuel Rail, Splitfire Coil Packs, Oil Cooler Kit, Haltech Plat Pro with 3 Bar MAP, Loom Tidy Up and Check, Ceramic Coat Exh. Manifolds, Exhaust Housing, Dumps and Front Pipe, All new OEM Water, Power Steering and A/C Hoses and a Hard Pipe Kit for Rubber Intake Hoses only.

TURBOS - haven't been purchased yet but most likely a customised twin set up in the range of GTX or -5

UNDECIDED - Type and size of injectors (probably 1000cc Denso) and suspension mostly.

Pretty much everything is ready to go except a little bit of ceramic coating and a few final bits and pieces. Hopefully it will all start to speed up a bit from here. Thanks again for all the help previously for anyone who contributed. Feel free to ask any questions if you have any and hopefully it won't be another 2 years for the next update haha

      After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive

      R34 25GT Engine Light 21

      Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.

      I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.

      No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.

      Can you mount the ATTESA pump in other locations?

      Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
