Rb25 Gearbox Into R32

[=premo=]

i tried doing this with mine and it didnt work so i sold the rsm and got a navara drive

Damn, that sucks. So I hafta get a new speedo cable with the plastic bit in one piece aswell. I've already ordered a AVC-R, haha, at least its a good boost controller, not just a speedo.

dunno bout that, i sold my AVCR also cause it didnt control boost for shit....

but yeah, i need a new plastic thingy for the cable also as mine has now broken... and you cant buy themk seperate from nissan, need the whole cable

Serious, I always thought AVCR was up there with eboost.

I've heard of people getting the plastic bit replaced with something stronger, was thinking of ways to make it myself but the hard part is getting it to fit back on the shaft (cable) because its got that bell shape around it so you cant get to it to make a slot or anything.

AVCR's are fairly good BUT you need some one with a dyno and knows how to set them up correctly.

Shaun appears to be a wizz with the avcr and pfc ebc kit.

The power FC has to be tuned so I'll get the AVCR done at the same time.

Anyone have a measurement for the tail shaft length??

Simply have the yokes swapped and tail shaft balanced.

Take as little off it as possible. Remove ~12-15mm removing the old yoke and weld.

Mine and Salads was done this way fits fine.

Balance and yoke swap is around $160. Get a couple done at the same time and its cheaper.

hey everyone just a bit back to the origin of the post, i have got the navara sender and r33 cog, put them in the gearbox but it was a tight fit, didnt realise that the sender had to be rotated 180 degrees with a slit in the side and now its stuck in there real good, snapped off some of the thread trying to get it out. any ideas on how to remove it?

[Cubes]

Spray WD in there and hope it helps the rubber seal to slide a little, then lever it out via the existing slot.

When its in correctly (180) its a fairly tight fit as the seal grabs if you don't use vaso or gearbox oil on it.

[Benny C]

yeah soaked the thing in wd and not much different really happened. might have to take the trade plate and take it to work so i can get it on the hoist, easier than crawling round on the floor.

turn it round first!

then remove it

Nah, I'm getting a one piece made up with bigger replaceable uni's. Don't wanna risk using the stock tail shaft with 350rwkw's. Did anyone measure the distance or did everyone just cut, weld and fit?

Cheers

355mm for the front section

355mm for the front section

So thats from gearbox to flange or from uni to flange, then stock second half?

thanks

I've attached a pic of the rb25det gearbox sitting in the car and the rb20 tailshaft up against the dust shield.

As you can see the 20t tailshaft sits slightly inside the box; by the time you remove/cleanup/chop off the old weld and reweld the new yoke on the dust shield lines up perfectly with the rb25 yoke.

Don't take off any more than you have to otherwise the yokes dust shield section will hang outside of the gearbox dust shield.

[Simon-S14]

sorry i should have specified.

yoke center to yoke center

PS, can you PM me drinkies number, ive lost it and i have several things i need to drop round to him lol

Premo, i get my rb25 yoke on Thursday so i'll be getting my tailshaft mod done soon at the same place as joel and showza (adelaide tailshaft services) might be able to get them done at the same time, even if your doing yours a little different to mine.

Thanks for the offer but I'm getting a one piece made up, a bit bigger and stronger. While your getting the tail shaft made up could you measure the distance between the diff flange and the furthest point of the gearbox just so I can make sure the tail shaft I'm getting copied is the right length??

The one I'm getting copied is from an R32 with SR20 and Z32 gearbox so it should be the right length but I wanna double check before I go get it made up, my gearbox hasn't been delivered yet so I cant get the measurement myself. Or If anyone knows the difference in length of an RB20 box and R33 box I could work it out.

Thanks

Pretty sure I mentioned this in another thread.. when we had my engine out to put the new crank/bearings in, I put my stock tailfshaft up next to that out of a 32gtst with an rb26 and 25 gearbox, they were practically the same length minus the saw cut (~1.5-2mm).

Nice one, thank you.

Thanks Cube's for the pic, makes sense now.

Simon, check your PM's

Premo,

When I spoke to Adelaide Tailshafts he said with the single piece fit the gearbox and measure from the output shaft to the diff flange. Thats your safest bet.
