Gtr R32 Revival - Advice And Recomendation

[SiR_RB]

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

[Anfanee]

So basically what i just said

[SiR_RB]

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

[SiR_RB]

damn you, posted 1 min before me 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

do it 1 time and do it properly.

You dont want to pull the engine out, have it fark itself in 6 months and have to pull it out again.

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

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
