Wax,s 260z 2+2 long term build

[waxhead]

Ha ha

ok you got me

 

Maybe i need the bigger diff huh

[waxhead]

I have been a bit quiet on this due to other things

Also been thinking about if i really want to do my l28 up and the answer is nah i want more exotic

So yesterday i went and brought my new engine an rb26det

I guess there is no choice now for the diff i will need the r200

If you are interested in any of the stuff i had for my l28 then let me know

The block is all bedurred and hot tanked , other than that the stuff will just sit on the wall

[RB30X]

so what l28 stuff did you have or are willing to part with??

[Aaron Neubauer]

my new engine an rb26det

 

Very interesting.............

[waxhead]

I will list it all soon

 

[waxhead]

I picked up a dr30 skyline diff for the car today

its an r200 with cv,s on it , from what i can gather its pretty much a bolt in for my 260z

 

price was right at 200 kiwi for the whole thing

Guess i will be selling my r180 now as well

Funny i will have no mechanicals left in this car that it came with

 

I will be rebuilding diff and will get a lsd centre for it at the same time

 

[RB30X]

Are you sure thats an R200? Looks a lot different to the two I pulled out of my 280zx's.  mine didn't have a bolted flange where the cv's go in, the cv's looked thicker and the diff looked wider. unless it's just the pics?

[waxhead]

Yeah it may be wrong i will have to look into it further before i pick it up

It does seem narrow im wondering if its out of a subarau

 

Ok your right kn31 is a subaru diff good spotting i was sold as a nissan skyline diff thanks for that

Im going to tell the guy thanks but no thanks

[Zedman240®]

I was about to chime in also; I removed my LSD from a 2 door R31 import turbo and that does not look like a R200. Theres a guy on ebay (username nnnn67 I think?) who sells R200 LSD's for around $990. It's worth that amount to save you the hassle of looking and making sure you buy the right one.

[waxhead]

yeah your right

I actually have an r200 out of a 2+2 coming i just liked the fact that it had cv joints

 

Lucky i have you guys to spot that before i stuff up and end up with the wrong diff

[waxhead]

Well managed to score my rb26dett this week

so its all go ahead on that , picked up the manifolds last week and have already ported them

 

Looking for an rb25det gear box at the moment to hold back the power

[waxhead]

I have stripped the head on the rband its in the tank now

Im just working on the rear sump for it now

 

.

[nizm0zed]

looking good.

 

your either going to need a spare block, or make a strong jig to bolt that sump to before welding it up, or it'll warp like a mofo.

even then, it'll probably need a skim anyway.

[waxhead]

Im going to strip the engine then stuff the bottom with wet rags and weld it on the engine

[garvice]

What about bolting it to a steel jig?

[waxhead]

Yeah would be awesome but i dont have a steel jig

do you have one

I would actually like to get hold of a stuffed engine block to use

[garvice]

Come on mate! I have seen your fabrication skill in this thread.

Take some 40x40 shs and weld that together. Add some cross bracing to keep it all square then just drill through for bolts. Shouldn't need every hole.

Then you don't damage a block and you have a jig when people say "Are you going into production with these?"

Or "I need a larger sump for my RB26, can you build one"

 

On another note, have you seen if all RBs have the same bolt locations for the sumps? RB30s can be had for real cheap (mate picked one up complete long block for 300). I am sure stuffed short blocks could be had for next to nothing.

[waxhead]

yeah I know i was just hopefull haha

 

Im not sure about going into production, im thinking about getting some laser cutout as it would be easier to put together

Or just cut some out of sheet at work with the gas torch

 

 

[Brabham]

Hi nice work,

                Is there any reason why the stock sump won't fit/ work? What about with an RB30? Thanks

[waxhead]

yeah i have to put the deep part of the sump at the back

[Aaron Neubauer]

Wouldn't modifying an RB30 sump to be deeper in the rear section be easier and safer than modifying the original?  Could always put some baffled windage trays in there while your at it! 

[waxhead]

Yeah thats a good idea

Using an rb30 sump, good thinking

[Zedman240®]

If you get a sump from a GQ Patrol, they have the hump to the back but its a little to low; you would have to remove some of it. When you see it you will know.

[waxhead]

do you mean the deep part is to low and would hit the road so to speak

[Zedman240®]

Yeah, I found a pic... You will see the sump has a lower rear part but then goes deeper again. That's the section you have to cut and just re weld. Also, grab the oil pickup and modify that to suit the sump.
