Engine Rebuild - Questions...

[GTRKat]

Hey Guys,

I am sure this is out there somewhere but I have been searching for ages with no luck! Basically I would like to rebuild my GTR at some stage. I want to do a full rebuild, mostly for strengthening so I can get some more power out of her and so I know that there are good quality parts in there and what stage they are at. I don't plan to wait until I break it, this is something I want to do in my own time when I am ready and when I am prepared (well hopefully this will be before I break it!).

So basically I'm just after a full list of parts that are required. I have seen various people's posts but they don't go into huge detail. I'm not after opinions on brands or parts at this stage, just a lost of parts themselves. Will research into certain bits as required when I find out what they all are. Figure I can slowly start purchasing and accumulating stuff

Any help will be greatly appreciated, I'm the first to admit that I don't know shit about this sort of stuff just yet, I learn as I go!

Cheers,

Kat

Bottom end parts

block

crank,

rods,

pistons

bearings (con rod/ crank)

Oil pump

Waterpump

Gasket kit

Timing belt

Bolts/ studs

Just to do the bottom end, you need to think about all these parts. I am sure i missed a couple.

Thankyou

Gives me something to start on!

You forgot piston rings...

[sl33py]

Not parts as such, but: budget for all the parts we can think of, and then x1.5 of the cost Everyone seems to find that...

[N1GTR]

You dont need a new crank

As long as your current crank isnt bent or cracked you can machine a collar onto the oil pump drive. Much cheaper than a new crank

[Bullet32]

What do you mean? - Of course he needs a new crank... Along with the rest of the JUN 2.8L stroker kit

Advice from someone who's learnt a few lessons the hard way and is home sick from work today with heaps of spare time for a long post;

Save up the cash, not the parts. Parts are becoming cheaper and cheaper. It wouldnt be very smart to buy pistons now ($1200 for CP's) for the sake of saying you've got them if you dont build the car for another year (when they'll be less than $1200) For example when i was thinking along the same lines as you CP's were $1500 for the set inc rings, but when i bought a set they were $1200, so i saved 300 by waiting, which paid for all the bearings

To put it simply, here's a list of parts i would buy before the motor comes out;

-Turbos (stock ones on mine were good to 262rwkw, but pretty fkd when pulled off. Go for a few drives in friends GTR's to suss out turbos, if you like the twins just get some 2860r-5's)

-Rods (Eagle, Carillo, PAR, Pauter, Tomei, JUN, HKS, SPOOL are all popular. Get Eagles, they're cheap and work fine)

-Oil pump (N1, JUN, Tomei, Nismo, Dry sump. N1 is popular, so is JUN)

-Manifolds (dont really need them, but if money's not an issue....HKS, Mines, Tomei)

-Dumps (HKS, Tomei, Mines, JustJap. Nows a great time to go for these as the motor will be out soon)

-Valve springs (Heaps of brands, popular choice is Tomei type A and B's)

-Tomei oil restrictor, only one version, under $30 delivered

-Sump baffles, again Tomei are most popular here

-Cam gears (adjustable, HKS make pretty ones)

-Water pump, N1

Leave the rest for once the motor is out, the above list should feed your craving to shop for a while, and by the time you've bought it all, you'll know what most GTR owners mean when they say its not cheap to build one

Money's not his problem?

HKS step 3 kit, full HKS parts through the head, GTRS turbo kit

Money will be a problem after that

[Bullet32]

He????

Whoops... I actually meant to say She. I must have missed the S key... Funny how its so easy to do but could be so insulting.

My bad

[N1GTR]

He's a she? Good to see another girl with a GTR

[GTRKat]

LOL she is a she!!!!

Yes nice to see some girls with GTRs around!! I've had mine nearly 3 years now, hence getting the bug to make it better!

Thankyou for the advice! Shall take it all on board. I'm basically compiling a list of everything I want to change and then I'll do some interim pricing and decide what's best to do now and what's best for when the engine is out.

I like brand names and yes I know its not going to be cheap! We have a "GTR Fund" that's currently being worked on!

Turbos are already done, they died few months back... Stocky turbos didn't like a full bar, I had about 3 days out of it before one went... Ooops Got the rest of the usual shit, apexi pods, power fc, boost controller, exhaust done already. And importantly I have a pretty new Grille that is on its way with Australia post at the moment!

[GTRKat]

And yes only in my dreams will I be getting the HKS step 3 stroker kit!! Would be nice though!

[N1GTR]

Oh, she IS a she

Got a pic of your car?

Seems like you've got your head screwed on correctly, the best advice any GTR owner could give to another is: Ask for more advice!

There's a wealth of information out there about all aspects of these things, and it never hurts to ask a question. If you're not going for mega power your build will cost significantly less which is great for your gtr fund. Have you got an idea of power you'd like? Like was it fast enough on stock turbos at 1bar? Or does it need more than that to keep you happy - if so, approx how much faster should it be to keep you satisfied? There's a heap of saving to be had if the power goal isnt stratospheric

Come to the texikhana at sutton road and have a go there, i found out that by driving at off road events (tracks) i quickly realized where my gtr needed money spent, and where it didnt

[GTRKat]

Haha yes she is

Yes I find it's silly to charge ahead and try to figure it all out myself or pretend I know it all! I'm really new at this and there's no point reinventing the wheel there's a lot of people that have been there before!

I've made a big list of stuff that I've given to the boys at Autotech to look at. From there I'll choose what I want parts wise and then decide on a plan of attack.

As for turbos I am still in two minds... Somtimes I have the feeling I went for the wrong ones.... Got the Garrett 2860R-7s and I do still have in the back of my mind should have got the -5s... In saying that I'll leave em on and do the rebuild etc and push them a bit and see what they can do. I guess that response will tell you that stocky turbos at one bar weren't enough!

I don't intend to be a dyno queen or anything like that but I think I'll be happy when I end up with somewhere around 350kw at all four wheels. I guess at that point it's definately time to upgrade brakes too. I think once it's fast enough I shall know when I get there. It bugs me to no end to know that at at the moment its at 280rwkw but it's max is 300rwkw yet I can't drive it at that because the injectors are fully maxed and it's going to break stuff.

I keep meaning to go check out these texikhana and motorkhana things. I was bad, last time I was hungover and in no state to drive but I may very well go check out the next one.

Here's some piccies, forgot to post these in here but some of you may have seen them on CC or in the R32 pics thread. I've changed the mangled number plates and I have my new grille sitting on the loungeroom floor waiting to be fitted.

[N1GTR]

White hey, good choice! Here's mine;

Whats wrong with your grille? Id add a few N1 parts and be done with it. Looks like a very clean car you've got there

I doubt -7's will do 350awkw, although i may be wrong - have a look in the RB26 results thread. Seems the guys with -7's are getting 300awkw without issues and the response is awesome.

350kw atw is a great feeling (mine did 355 before letting go, being rebuilt now, will do more than 400 this time round), pretty much nothing on the street can keep up. Traction is actually an issue if you're hard up it

Dont forget the fuel system, the easiest way out of that problem: 044 in tank (yes it fits and works fine), new FPR (nismo or sard), new injectors (700cc's), standard fuel rail. No need for a new fuel rail unless you're after some "bling"

The brakes - i thought the stockers would be ok for a while while i decided what to replace them with. Wrong They just plain old suck with that power. I have zero confidence in the sumitumo's after upping the power and wouldnt recommend anyone keeps them when at that level of power. Ive now sourced some new brakes that will stop it quickly enough;

Front:

-APRacing 6 pot monoblock calipers

-375mm discs

Rear:

-APRacing 4 pot calipers

-330mm discs

Problem is though, they cost well more than most people spend on engine mods. An easy upgrade for the R32 gtr is the R33 brembo's, there's pretty much always a set for around 2k, but i think they should be much cheaper through the right people. May be worth your while sending a PM to Mr Zac, he's an importer. Or to Lawrence, he's an ex pat in Japan, and he's VERY helpful

Next weakest link would be the gearbox, worry about that when/if it breaks - not cheap though which is a shame. Id be VERY suprised if there isnt a huge markup in gearsets

Then enjoy the thing

EDIT: Looks like you've got the original badge on there aswel - thats pretty cool, not many do these days

[GTRsean]

Thats a bloody clean looking GTR Kat. Kudos to you keepin it so clean. Sounds like it's going to be a project and a half for you guys.

Mines collecting dust lol, and I'm having withdrawals not driving it.

Wipe that dirty arse Steve. Oh and if you had got the pistons through me it would have cost you $835
