Boys,

Got the RB25 into the MR30 and things arnt looking to bad, apart from the transmission xmember. I read somewhere that some one made a successful transplant with one out of an R31. Has anybody actually done this. And if not what have others had success with.

manual or auto rb25?

[elrohir]

Manual.

[rsx84]

the rb25det gearbox is bigger than the rb20, dont know if the rb25 box is the same as the det version though so you may be in a league of your own with the x member there pm ghostrider as he'll have somekind of answer for this one, sorry dude!

They couldnt get the brake rotors for my car in the end

Crimmo, if its ok I'd love to come and have a look at how your suspension and brakes are set up, cos I'm going to have to do something similar very soon as my rotors have been skimmed to undersize so that its still driveable until I change to a rotor thats more readily available

I just live around the corner btw

Cheers

Adam

Adam,

Our DR30 RSX rotors are exactly the same as early model Z31's

Fronts are DBA # 608 and Rear DBA # 605

Whoever told you they can't get them needs a manager (so that he stops handling himself)

When I spoke to an agent of DBA's a few minutes ago, I was told they're ex stock DBA.

Cheers,

Dennis

Gearboxes:

The RB20 DE & DET are identical and same as R31 import box from RB20 DOHC engine.

The RB25 DET box is an entirely different kettle of fish, it's about 2 times the size and has the same ratio's as the GTR and come from the R33 GTS 25t

The crossmember is a FABRICATE it yourself deal, as it mounts a further 100/150mm further back. The fabrication is a good idea as when we do these conversions, we tend to get heavier right feet and on hard launch, the standard mounts JUST DON'T DO! Think about NISMO mounts as well, engine & gearbox.

And Matt,

Going to get you a postage cost tomorrow and will PM you the result.

Cheers guys,

Dennis

Does that mean the struts are the same as Jap R31's?

[elrohir]

ghostrider. ah any code on were i can get a set of nismo mounts both engine and gearbox. Thanks for the info on the cross member, i'll look into.

NO! Where you get that notion???

UAS at Castle Hill has them, but don't fall over when you see the price.

But they better, they URATHANE, so heeps stronger, stiffer etc, etc.

What I did is check the level of the gearbox stock, and chocked up the R33 box to same point and then used a standard xmember as a guide to see how thick it had to be etc, etc.

Are you using an R33 box or R32/31, RB20?

[Ghostrider]

Got a little erand for those guys with MR30/HR30 doing conversions.

Anywhere in your travels, there is a plastic snout as the cold air intake on the stock R30 air box inlet, there is a similar thing on the R31, but don't know if same.

I need an R30 one for my MR30 L24ET Ti Hatch,

ANYBODY HELP???????

[Adam_RSX]

Well the Z31 brakes are the same as R31 Import and R31 GTS1/2, so I figure the struts might be the same?

Not quite! Similar in size, but R31 are "HAT" type rotors, as they go over the hub, where as DR30 & Z31's bolt onto the back of the hub.

[Adam_RSX]

But in any case, I would be better off changing to R33 non turbo discs and R32 callipers like Crimmo's car?

R32 GTR is the best way to go, it's the upgrade that Jenesis - Japan sells and uses. 296 x 32 Rotors or Z32 which are 280 x 30 with Nissan alloy 4 spot calliper.

The Z32 set up is easy to get and a good balance with our 290 x 10 rears.

Secondhand Z32 fronts should cost you about $550.00 discs & callipers.

Ghostrider, the engine and box came as one off what i think was a late model R33. however the engine is a neo model. which a friend told me was strange because they only came on R34's but not sure on that issue. I think that might answer some of your question.

Has any one replaced the bushings in the rear cross member? I would like to do so but not sure where I could source new ones from or would it be a custom made type thing?

[Adam_RSX]

Ooh, and the bushes on the strut tower to engine brace. Mine are fsucked

[PHaT MR30]

noltec sell bushe kits think they are www.noltec.com.au

I replaced my rear xmember & diff support bushes with urathane.

Noltec made them Custom $450.00

But take some advice, if you want your car to handle, don't use urathane in the pivot point bushes unless you can affords to replace them every month

i have a l24e and l20et as they are different and the r31 is very similar to the l24e one in length, the l20et is a lot shorter than the l24e!!
