Hey

just wondering a few things.

i have an HR31 import R31 that came factory fitted with an Rb20. I now have an R32 RB20det and R32 RB20det 5spd conversion in my car.

My question is... if i was to get an RB25det 5spd box would would i need to change? Would i need the rb25 slave cylinder or would what i have suffice ?

Cheers :)

Dave

need to modify tail shaft to fit 25 yoke, need to modify crossmember to suit box (not a huge modification) and need 25 slave cylinder to fit on 25 box, its slightly different to 20 slave cylinder, could probably do something to make it work but 25 bolts straight on. Other then that, easy conversion

yoke and tailshaft should be a problem... Hardie(sp?) Spicer seem to be the ones to contact... cross member, easy as... I was just concerned about the slave cylinder. If its a direct bolt on replacement for the rb20 one i am happy :O

Cheers for the info RB20LagWagon

Don't know if this is any help to you but I was asking people at wreckers today about putting a r33 g/box behind my r32 and a couple people said all I need to change is the front tailshaft to the r33 one. I don't know if this info is right as a lot of people talk crap. Can anybody verify this?

      This could be sold and shipped to the US for many gold pieces. RMS has no say in that. Ask various Western Sydney inhabitants how it works.

      Ha ha ha, mine loves to spend, all on the dogs (they're our kids, and her spending would likely rival that of some people raising children!) the only benefit is, her spending is tax deductible as she runs a business in the dog industry 😛 The above all means she can spend race car budget quicker than I can. 😛 That and a lot of the things I want are very expensive, and I can be a bit "you want how much for that?!" And at other times overly impulsive. Or I start the w days of research, get to day 1.5 and get really annoyed that no one will advertise actual specifics and it's just marketting BS and I go "well, now I don't want anything to do with that now!" Also I hate paying lots of money for something I can make from $50 in materials. Then I get the shits halfway through making things and wonder why others who just buy parts have more fun... 😛

      Their 240Z with the RB26 would be a real nice thing to have in a garage to come out for an occasional weekend cruise It's such a cool thing in so many ways Sadly, we have a blue 240Z shell that I walk past every day, just sitting outside a shed at work, it has been slowly disintegrating and falling apart into the ground for the last few years, the owner cannot be found, and I am unable to "claim it" I've been told by work and the RMS, the rust in the body is excessive though, and it has had most of the salvageable stuff, like panels, trim and switch gear stripped off it over the last year or two, work keeps threatening to put it in one of our metal scrap bins, I wish they did though, as it makes Mark sad walking past it

      Good tips, I like it! 😂😂 My wife is a LOT more frugal than me so it's only me we need to worry about! A splurge to her is buying 2 pairs of socks in one visit at Kmart!

      Haha, the appropriate response to the question "Is this new?" is "I've had this for a while.". With the unspoken small print that a while may be the time since this morning or five years ago   And to be fair I learned that from the best, i.e. my wife. Because it goes both ways.
