Vn ss t56 conversion

[mws]

Hey everyone, I've been searching for what seems like ages for some info that isnt confusing. I want to put a t56 in my vn ss. I'm not sure on what is involved parts wise. Does it actually bolt up or do i have to by a bellhousing from somewhere like CRS? As far as i aware a few guys on here have t56's behind their 5L's did you guys use a vs pedal box and stay hydraulic? and what clutch did you use or make up a bitsa with a different centre piece to suit the t56 input shaft? also tailshaft and wiring what needs to be done? Sorry for all the questions i just want some direct answers and searching the threads isnt helping too much, and feedback would be very appreciated, im sure im not the only one who would like all this info in one place. Im really keen on this conversion this is the first auto car ive owned in ages and its reminding me how much i dont like autos lol.

And if anyone does find a thread with this info that ive missed please post a link

Well, the HSV GTS-R came out with the T56 behind the 5.7 litre Holden V8 so a bellhousing may be still available from Holden/HSV if you choose that path. I believe the OEM part number to be 07B1711924 for the bellhousing but it may be listed as a different number in Holden's parts catalogue.

Best person to speak to about the conversion would be Mal Wood (Mal Wood Automotive). He installed a T56 into my LX Torana. Excellent job, can highly recommend him.

t56 was in the vs series 2 and onward. Same as T5 just get yourself a hydraulic pedal box out of the vsll or above. So no bell housing no sneaky little things, just a normal conversion from a later model

All holden 5Ls only have the 5 speed. What 6 speed are you talking about? VR and VS HSVs with the stroker motor had the 6 speed.


As said above, contact mal wood, and he can supply you any part or all of a kit for a 6 speed conversion.

Heres a pic of my box when it was delivered (note the black spacer plate on the bellhousing).
Also i'm still using cable clutch, i saw no need to upgrade to hydraulic.

a adaptor plate? interesting. it also looks like the adaptor plate has the hole for the clutch cable?

if you do the T56 conversion you will also need to change the diff ratio to make use of the ratio's in the new trans. i suggest either 3.9's or 4.11's

Yeah it has cable still, thats what i wanted!
I have 3.73s atm, will upgrade then next time i blow a diff

i think cable is better also, much better feel for what the clutch is doing. every car i've driven with hydraulic clutch has felt awfull. i'm just miffed with that adaptor plate. i would have though the basic bolt pattern was the same.

Its a late model T56 tho, not a VR/S HSV style 6 speed (assuming their different?)

How much did your kit cost stealthy? i was lookin at trying to do it a little cheaper if possible i can get my hands on a t56 out of a vx ute real cheap, what was in your kit apart from box? Im assuming ill need to get mal woods clutch fork, adaptor plate, clutch, some form of different tailshaft...? Also what wiring did you do to get your speedo working and reverse light and that? I've done t5 converisons is it similar to that? thanks heaps for the help so far everyone

it does look like the top 2 mounting bolts on the late model trans are different

The box all setup ready to go was $4000. Was another $1000 for the clutch to suit.
Mal wood can supply a whole kit if you just need the parts. Not sure what it will cost tho.

Tail shaft is identical (assuming its already manual, like my car was)

The wiring was just a pulse sender of some sort. Havn't even had it fitted yet lol

[mws]

i think i will email mal wood again about the parts minus box. At least tailshaft is easy i thought you would need a different splined yoke or something, So you havent got your speedo wired up yet? lol. this is turning out to be an easy conversion i just need to aquire the parts I can easy fit this all up. Did the clutch they supplied you look like same size as a standard 5 litre one? I should be able to use the friction centre piece out of a t56 style clutch vt or whatever and just use the 5L pressure piece.

[mws]

oh another thing while i think of it does the shifter fit same location as t5?

[STEALTHY™]

The box will already have the yolk, just bolts up to your unijoint (you can see it on the back of the box, with blue strapping going through it in my pic). I'd assume your box will come with the same.

If your car is auto atm, you will need to get the front half of a tailshaft from a manual to be the right size.


Shifter is almost identical, it will be slightly closer to the driver, but it will still operate fine. Goodluck finding a console cover tho

All holden 5Ls only have the 5 speed.

My mistake, yeah the t56 was only in the 215's. I thought they were all hydraulic though. Obviously not but if your using a cable.

Yeah they are all hydraulic, but you can still set them up to use cable!
Series 2 VSs with the 5 speed getrag are also hydraulic. I couldn't tell a difference between driving my mates with that, and my cable clutch, although i was used to driving mine all the time obviously.

[mws]

thanks heaps for your help guys espicially stealthy. Looks like i got some saving to do, but i think i go the same way. I would definately break a t5 i did in all my v6's... The console piece will suck to find but if i can ill modify and make my own from a spare auto on i have. Is there a thread onm your car stealthy? I reckon its heaps nice i wanna see more of it.

[STEALTHY™]

Nah no thread man, if anyone wants to know anything about it they can just add my msn

[mws]

I think i might do that If thats alright im not on there very often but it'd be good to see some pics, get a few ideas and stuff. I can't do much right with my ss but, just found out yesturday i have a month left at my job then im out so thats a bit of a bummer.
