unless you want 4wd theres no point as a t5 gearbox will handle plenty anyhow

 

their is loads of skyline's bein broke ebay and gtoc

 

Man oh man england is the land i wanna be!!!! Good beer, beautiful landscape, nice people, the best football teams and THE biggest carscene in europe. Only the side u are driving is a little bit strange LoL But had never troubles every time i drive to London with my Ducati.

 

I have Problems to upload attachments, can u have look in my "garage" there i have upload a picture of the clutch and the release bearing.

Thank very much!!!!!!!

 

just had a look the clutch and you have a push type but the release bearing is a pull type.is your clutch arm a pressed steel type that pivots on a ball? if so the pivot ball is the weak spot,especially if you have a heavy clamping pressure plate,you can buy uprated ones of the net.
the only point i would make about about push type clutches is that the slave cylinder sits in front of the bellhousing and may get in the way of the front diff? better of converting to concentric release bearing,there's loads to choose from you just have to make them fit.

 

Is this the write bearing?

Oh man! "right" not write! Sorry I only had technical english at school! LoL

 

yep thats the correct bearing for you

 

well i have got my skyline box in and running,i use a pwm motor controller from maplin to control the variable torque split 0-500psi or power up the fail safe coil for 0 pressure and 2wd.

I've been following your thread for ages mate on here and XROC. Top work and well done for getting it all done and not giving up! Solves the crappy mt75 problems. And you get the best of both world 2 to 4wd .

 

50/50 torque split is achieved at way less than 500psi!

 

thats good to know,I have had it at 150psi max in 4wd and it launches well on that,I won't know untill i get a readout from a rolling road,i suppose you went thru this years ago.I will aim for 60/40 bias to rear split max as i don't want to munch my front diff or break the mini front standard prop i have.

 

i take it with your bias adjuster, its a voltage regulatr to reduce the pump speed down to give you a desired pressure?

ill be looking into the 6 speed vr34 box, hopefully ive made enough room in the tunnel for it, but then ive put a full skyline front tunnel in my car so i canuse the skyline mount aswell

 

well i was going to use the 6 speed but even 2nd hand people want stupid money for them,i got all the r33 gtr vspec stuff i needed for Ł500,i did the whole thing for Ł1200 which is far less than people want for the 6 speed.

The controller does not control the pump speed,the pump runs and fills an accumulator to 500psi and is then turned off by a switch, then there is a variable valve which is operated by a coil to adjust the output pressure,the coil is operated by the same means as injectors,its pulse width modulation,the controller i have is a 12 volt 3amp max pwm motor controller(a 2amp max will be better)the more current flow to the coil the more the valve spool moves and thus the more pressure you get.

 

How does the torque split work on the skyline box? is it a multi plate clutch system?

 

yep certainly is pal.

 

any more news on the bolt on conversion

 

im sure mark mk motorsport could sort a kit out id be intrested

 

the problem is you cannot really do a conversion plate, I looked very hard at it, and the starter position is just too far out, so you would end up modifying flywheels if you retained the skyling orientation, or you would have to cut a large hole in the skyline box to get the starter back to the original ford side..

Mine is currently on the mill, the MT side has been milled, and the skyline bit is on ready for doing then welding.

Its slightly different to the V6 conversion as the V6 has a deeper flywheel/crank spigot, but now impossible.

Im having to be pretty careful as i run a tripple plate clutch and the skyline splines are pretty short.

 

+1 ............

 

its close with the v6,i had to use a 2.8(10mm thinner than a 2.9)flywheel and skim that down as the twin plate i use would'nt fit in, mind you if your going for a push clutch with a concentric release then it would be better,i needed the room for the clutch arm to move back as mine is a pull type,i was just watching the pennies when i did it and utilised all the skyline components.if you want to make some more i'm sure you'll have a que at your door!
another thing i have noticed is the box does make a noise in 2wd as the plates rattle about a bit,but i am certainly having fun putting into 2wd just worried i will end up in a tree.
i'm just trying to source a 0-500 psi pressure transducer and gauge as my analog oil filled pressure gauge is slow reacting and i want something a bit more permanent,if i find something at decent price i will let you know.
i'm also going to change my control as after a run at santa pod it was tricky fllicking 2 buttons after first gear,so i will using a single 3 way switch,i should of thought that one thru a bit more!

 

Hi, yeah will use the concentric slave, and yes it is a bit critical and close i suppose, as for making more, no thanks, no time or inclination really !! its taken me more than 6 months to get round to doing mine lol !

I would be interested in your control setup though, I would like to adapt it to look at propshaft speeds, it also for me, needs to un-couple when i pull the handbrake, and go to full lock when i press the foot brake.

 

I know the feeling about making more,so far i have been asked to make 2 v6 boxes and 3 2ltr cosworth ones but i don't have the time like you it took my spare time to build my own.I think the conversion is only really cost effective if you do all the work yourself.
If people want to make there own i don't have problem helping out with what to look out for,this is what clubs are about, time is money but advice is free.
Cutting the 4wd with the handbrake will be easy,just use the handbrake switch on relay to power the failsafe coil, but as far as the rest that will be interesting,sounds like you need an electronics expert to make you a control board up.mines as basic as it gets.if i wanted to go down that route then i would fit all the skyline control electronics,its very clever stuff with g meters,wheel sensors etc,i don't think its impossible to replicate but it would be easier just to fit all the factory stuff.I do know someone who could do it,he's in charge of all the electronic design for the company I work for,i will collar him next time i see him and ask.

 

Even in my 'not too electronic brain' the thought process of the speed differential is pretty simple i think, and also for the launch control my ecu would output to the hyrdaulic unit to lock the centre diff until the launch stategy is completed, then just process prop speeds and then hand and foot brake as inputs.

 

im more interested in the electronic side, ive put a front half skyline gtr tunnel in my car to run the skyline gearbox, but as i want to run the r34 gtr box id like to try and get all the skyline electronics working for the gearbox, but as you say it runs off g meters, wheels sensors, abs sensors, speedo ete etc it starts to get really complicated but not impossible

 

id like to put one off these boxes in my car

 

i thought of this but no one replyed putting the abs off the skyline in so the skyline electronics could just be used nice to meet you, graham. on sunday you spell it differant your my new best friend

 

Very easy to do Mark even with a manually variable system.

 

have you thought about just getting a Skyline?

 

yes but then i bought my escos instead as its a car ive always wanted to own, im only running the the gearbox and said id like to run the full ecu for gearbox, dont see what the comment is aimed at considering people have said the same and people are using the gearbox already

 

I think that Lee's getting at the amount of Skyline parts needed to run Nissan's control system, I know what's involved and I wouldn't go there!

 

ah got ya, just came across that i should of bought a skyline sorry

i know theres a lot of parts required to run the transmssion ecu as the skyline tuners told me how it works and if i wanted to run it like a skyline it would be a lot of work, but its not impossible just a complete pain in the ass

but i would like it run as near to how it works in a skyline so rwd most of the time until it loses grip then the 4wd system kicks in, or would it be best just to have it activated on a switch on a switch so rwd until you turn the pump on and then adjust the pressure going to the transfer to get the split you want?

 

how hard is it to do this martin

 

having done a few miles with my skyline box,i would say to use the attesa complete system would involve alot of wiring,g sensors etc,why bother when you can just set it to want you want,
my car feels alot more sure footed in the bends as its a set torque split before i go into the corner,i don't want it to lose traction and then react,i want to be the one to react and not the car. its better to have it there ready and waiting to be used.you can adjust it on the fly to suit whatever your doing,also if you fit the nissan controller with an r33 ets pump, then you will not be able to go 2wd manually,if the fail safe coil is disconnected then the controller will know and it will keep putting up fault codes.

 

yeah likewise,as i said i was sat in the que waiting to go up the strip and i thought i must find that graham c, and there you where on the big screen next to the pits being interviewed about your car!.
It was a bit of nightmare day at the pod as i left my hydraulic gauge on a customers site,so i had to be careful how much 4wd i could apply,but I had the weirdest fault i have ever had when i launched the car in 4wd,lost fuel pressure for a bit,i drove the nuts out of the car all the way home and it did'nt miss a beat,i have come to the conclusion my car just doesn't like going to shows.

 

im going the r34 gtr 6 speed in mine, looking into the electronics its not with fitting everything, so just going to use the pumps and have it ona control to adjust the split to how i want it

 

am going same as greame/ scarabman think its the easrier way just going to get my rad working in the boot then am on it

 

had my car on the rollers for the first time with the skyline box,I found that 120psi is 60/40 split and 200psi is 50/50.
very weird seeing my car on the rollers in 2wd mode.
