Gtr Engine Rebuild. New Stock Crank?

[R32 TT]

Hi Guys,

Just about to rebuild the engine in my R32. Am putting together a shopping list and wanted some help.

Since I have a '93 GTR, from what I've read there is an issue with the crank to oil pump collar mating surface, and that there is a mod to fix this. Again, from what I've read this mod seems to be about $500 by the time its all done and dusted.

A quick look around, and it seems I can buy a brand new R33 Crank from UAS for just on $1000 though. Does this seem like a better idea? Obviously a little more expensive.. but replacing a 12year old crank with a new one and not having to stuff around with it sounds good?

Does anyone know of other crank alternatives/prices?

And lastly, if I got a new crank, what preparation would people recommend? For example, any toughening processes or other. (I was considering having the crank knife edged as well - recommended?).

Just for interest, my other bits on the shopping list are:

N1 Water Pump

N1 Oil Pump

Tomei Oil Restictor

JE Pistons - Totalseal rings

Crower Rods

Bearings (suggestions?)

Tomei Sump baffle (other suggestions?)

Lightened Clutch/Flywheel setup - not sure what yet, want to keep a good street pedal feel if possible.

Head work at this stage was just going to be limited to a general service and probably put 260 Poncams in.

The car will see circuit track, street, the occasional drags night, Hill Climbs and that sort of thing.

Is has Motec ECU, Motec CDI, R34 N1 Turbos and pipework to match.

Hoping for a solid and relaible 500hp at the flywheel, but with a responsive engine.

I figure the stock crank should be good for it? Especially when running the lighter pistons/rods and so on?

Any other suggestions with regard to oil control might be helpful too, as I've heard this appears to be the weak link and not sure if the above list covers all bases.

This is my first experience with a RB26, so any "look out for this" type help would be very much appreciated!

use the 33 gtr crank, by the time you machine your old one etc it comes to the same $$$

less hassle getting one new, thats what im doing with my 32gtr/26

Did the same, get a new 33 crank, less hassles.

Doug at Rockingham Nissan can do the R34 GTR cranks cheap also.

Tomei metal gasket kit is a good idea as they have head,all intake and exhaust gaskets and the oil restrictors for a good price.

We normally keep all this in stock in WA.

Ah ok cool. I was going to ask this actually. Is there any real difference between the R34 Crank and R33 Crank? - I'll give Doug a call - cheers!

And where abouts are you for getting the Tomei gear?

yer get the tomei combined gaskit kit for from greenline. Also if hill climbs and such are your thing would go a custom sump mine is about 7lt no oil cooler other shops sell 9lt sumps. im using kings race bearings but most people use ACL bearings. Yes buy the new crank

Any recommendations for the custom sump?

Quite a few people seem say the Tomei insert is ok, but I can see that adding capacity can't hurt either...

Who'd you get yours from?

Im using the Trust enlarged baffled sump, only a tad more expensive than the Tomei baffles alone, while providing increased capacity, modified pickup and a baffle cylinder.

Trust extension is a must.

Top racing do Tomei in WA 94588155.

Well - 'Speed costs money - how fast do you want to go?'

A rebuild could be just a set of rings and bearings and a 'freshen up'. Or full-house build doing pistons, rods and crank etc.. I guess it depends on what you are doing with it.

I am trying to build something that will see some track work, so I have to balance my budget with things that will allow the motor to 'live' when its at revs on hard corners. So my build is going to include things like new oil pump, sump modifications and so on. But I am not going as full on as someone building an outright race car either.

You could easily get more power than I am aiming for by spending less money. It will most likely live on the street because it doesn't see the same temperatures or get held at high revs for as long. If you aren't doing track work, you may not really need sump modifications at all.

But I am doing the same as you, trying to find out from others what the 'balance' needs to be for what I want to do with the car.

Doesn't really answer your question I know. But the answer is 'it depends'.

Great! Thanks for that - I'll give them a buzz and doing some sniffing around on this.

The Trust Sump is a new baffle and everything is it? I have to cut the old sump and weld this on etc?

Is the Tomei baffle coupled with say an oil cooler as good an option? (since the oil cooler will add 'some' more capacity) Or is the Trust unit a superior baffle besides the actual capacity increase...?

greenline is good !

used them befor it about 2 week wait from jap

Go the R33 GTR crank, better option.

Bolt on sump baffles are good -custom baffles with one way metal trap doors are better, also larger capacity sump, oil restritor in the head, an external line from the rear of the head to the sump.

R34 GTR crank is no different to the R33 GTR crank.

Contact Greg from Proengines, he goes by the username of proengines on here. I have had my engine rebuilt by him and he is exceptional. He would be able to answer your rebuild questions & if you search his previous posts he goes in depth & is very helpful.

[blk180]

The people that did my rebuild also modded the sump. I dont have a full custom sump. I have tomei sump baffles inside as well. the trust sump how much lower to the ground are they Blitz. Also as above i have a return line from head to sump,oil restritor in head and the head and block drains for oil were enlarged.

hey guys, can anyone reccomend somewhere in sydney to get a rb26 crank from and roughly what it should cost?? i've spoken to a few places but havent had any luck yet really, thanks...

[pnblight]

there only one draw back with the TRUST sump it hangs below the cross member and if you ever run a curb etc (track day) the first thing to hit will be the sump, this is the reason why so many people build custom sumps that go out to the sides instead of down. Not saying don't but just making you awear.

I don't see why a crank collar properly fitted would not be good enough for 500hp. It costs half as much or less 'but I might as well throw $500 in the river since I'm rebuilding the engine anyway'. Note sarcasm - not rudely meant, just easier to use.

Also those pistons will not likely be lighter will they? More likely the opposite. Dunno about the rods.
