can they be switched between 2wd and 4wd

which box is best to use (r32,r33 or r34)

what sort of power can they handle as standard

how much bigger than a 4wd cossie gearbox are they

any help is much appreciated

I believe its only the R32 that is switchable iirc, but i may be wrong, and should be ables to cope with 550+hp again iirc

scoooby slayer

iTrader: (4)

only r32 is switchable afaik and tweenie said should be ok up to 550 bhp, 600 if treated with respect

is it cheaper to do the reyland type conversion with a standard skyline box when compared to a bara type box??

All skyline 4x4 boxes can be switched to 2wd, but only the 32 box can be ran 2wd without causing centre diff damage.
33 and 34 boxes will drag the centre clutch and overheat in time.
Big bonus is the power they can take, but there big

So are any of them permanent 4wd then? i.e. same as with no pumps fitted?

I always thought they were all 2wd until the rear span up and the jiggery pokeries kicked in?

robrs2

Yes they are 2wd with slip drive to the front. But the later boxes have a fair bit of electronics to run them and yes the pump and bits are needed

jonesymk2

iTrader: (2)

so i need an r32 box then

is there much work needed to the tunnel to clear the box

where would i get a pump from,with the pump running whats the torque split like

how does the speedo work is it electronic or cable

iTrader: (2)

the R32 and 33 are almost identical the transfer is the same and can be used in 2 or 4wd, without pressure they are all 2wd, its only when you ramp up the pressure on the clutch pack that the transfer sends drive to the front.

i must have typed my replies in a foreign language,and posted very blurred pics.

jonesymk2

iTrader: (2)

saw the pics mate but not much info with them thats all so just wanted to make sure i had got everything right,who welded the bellhousing on for you,did you have to modify the tunnel much to fit the box,is it an expensive conversion after the box has been bought

jonesymk2

iTrader: (2)

soory mate i didnt notice you had edited my post in your reply

lloydmotorsport

iTrader: (1)

the pics i posted are of a r33 gearbox,the 2nd is of the pump to run the box. i used these in my mk4 escort,with cos 4x4 conversion.there are quite a few on ebay,so have a search,and you can see the differences to the r32 box.

you will need to extend the tunnel by 30 cm on the drivers side for the transfer case,and up by 15cm around the gear lever.

you will need a rear prop making
hydraulic center push clutch
if you use the liner pump,you will need a controller from reyland
i used a mocal oil pump,and a return valve to vary the pressure,worked very well.
0 to 50 in 2.3 seconds,

martin should be able to get the bell housing welded for you.

iTrader: (2)

i need to get a rear prop made anyway mate as its going into my mk4 escort estate so thought while im still doing all the metal work i would do this save doing more work after the car is complete,i will give martin a call one day this week or next week,do you have any pics of the tunnel mods atall please,what did you do for the front prop

robrs2

Although for a V6 ford its the same.

lloydmotorsport

iTrader: (1)

use the liner front prop.
search lloyd,in restoration forum.some pics in there.

lloydmotorsport

iTrader: (1)

i ran my box in rwd for many motorway miles, and had no problems,
also ran it in fwd mode when i broke the rear diff.

jonesymk2

iTrader: (2)

does the skyline front prop fit straight or does it need modifying with the cossie front prop

lloydmotorsport

iTrader: (1)

straight fit,

jonesymk2

iTrader: (2)

thats one easy bit then lol

this sounds like a cheap mod for big power cossies ill keep an eye on this

cheers mate i will have a look on there at the weekend

shame reyland have stopped doing the gearbox conversions like above, else id be having one in my escos

i dont know anywhere or anyone else who can do the bell housing conversion now

lloydmotorsport

iTrader: (1)

i could do this conversion,but i guess the price would be around the 3k mark.drive in drive out.

robrs2

Try David Howard

Psycho Warren

iTrader: (5)

how come reylands stopped doing the conversion then???

lloydmotorsport

iTrader: (1)

i guess they are too much trouble,for little profit.
fixing the new bell housing on,has to be precise,flat machined surfaces.so the the box needs a complete strip down.

iam sure martin still does the 11k conversion,to the os gieken box

Psycho Warren

what are GTR boxes like with launching??? If they can handle 450 plus BHP and still survive the odd launch then with the added flexibility of selectable 4wd/rwd then they must be a stong competitor to the bara type boxes.

xr4x4rs

iTrader: (5)

ive never been in a car that launches like a 500bhp skyline, it just gripped and went

plus theres a lot of work involved, like half the tunnel needs to be modified and you can never go back to a std gearbox again, due to taking out the original gearbox mounts, custom props made, hydraulic pumps for 4wd system, custom bell housing, clutch, and hydraulic clutch conversion, custom gearbox cradle, theres loads of worked involved in doing the conversion properly, ive been looking into this since it was started being done, and even had llyodd do my tunnel ready on my sierra but scrapped the shell lol

was sriously wanting it for the escort cos as i can get a skyline gtr box ad eerything easly, its just the bell housing im struggling to find sumwhere to do, but now im going to stick with a bara i think

jonesymk2

iTrader: (2)

trouble is my car isnt completed yet and have still got loads of work left to do on the shell thats why im looking into this conversion as a bit more welding isnt a problem on mine at the moment,do i need to use a cossie bellhousing or is there another bellhousing i could use instead

rsnissan

iTrader: (9)

Seems likeit could be the answer if the rest of the fabrication work wasnt such a pain in the arse. I presume onece this is all done the OSG box would just all bolt up if you wanted to upgrade?

Martin-Hadland

iTrader: (2)

Not true!! Dangerous's car had a Skyline box that I fitted when Sean owned it (thats the one Lloyd bought) and now it has an MT75.

It was mentioned that the Skyline front prop is a straight fit, that's not the case.

Martin-Hadland

iTrader: (2)

Yes and no! The OS Giken box is not the same shape as the standard item so it depends on what tunnel mods were originally done to accomodate the standard Skybus box.

The OG Giken conversion uses a proper belhousing thats only available from myself.

jonesymk2

iTrader: (2)

what mods are needed for the front prop then or would it be easier to give you a call one day next week if thats ok to find out from you what work is involved and what is exactly needed for the conversion,i need to find out what clutch to use aswell and will i definately need the centre push hydraulic clutch

scoooby slayer

iTrader: (4)

ive read on gtroc some clutches are push some pull dependent on age.

im watching this as well lots of skylines here in OZ.
