VN manual pedal box into VH
Looking at putting a VN 304 5 speed into my VH... Doin all the research. Gunna be a bugger of a job! But anyhoo, can anyone tell me if the manual pedal box from a VN will bolt into a VH? I have heard they will but someone else has also told me theyre welded in..? Anyone?
Cheers for any advice.
The conversion isn't too bad mate.. The pedal box doesn't fit, slightly different mounts. Best bet is get a vh one from the wreckers.. Cable still hooks on the same.
Thanks heaps mate.
Saves me going to the trouble of pulling out the VN one then!!
Does the VN T5 box/clutch use the same cable setup as the VH pedals or is it hydraulic?
Cheers.
if you get into any trouble trying to find a pedal box at the wreckers, you could take ur auto pedals to dellows engineering n they can exchange it for manual pedals for about 250 bucks. vn uses hydraulic system vh uses cable system
Vn is still cable, all the commo t5's were. I've used the vn cable in my vk and it hooks up fine.
Rough pointers for the conversion, use vn front end, with a vl lower section of the steering column, gearbox cross member is an interesting one but there are a few ways of doing it. Put a later model fuel tank in and and all you have to do is add a fuel return line. Wiring is fun, again there is more than one way to skin a cat, you can get adaptor looms that are pretty much plug and play if you don't wanna do it yourself.
I did it the hard way and used the vn loom and modified the hell out of it to work with a vl dash.
Any other questions ask away there are a few of us on here that have done the conversion.
Forgot to say the reason for the vn front end is to solve the exhaust clearance issues without having to use the pacemaker extractors made to work with the conversion.
Thanks guys. Cheers for the answers.
ive been doing my research and so far, my plan is to put the VN K frame and p/steering rack in. I understand I will also need to get a VL intermediate shaft to link it up, which requires the steering column to be taken out. Was going to do the pedal box at the same time but just a little unsure on what I need to source. Sounds like a VH V8 manual pedal box is needed as the VN one doesnt fit. Can the VN one be made to fit? Or is it too much of a pain in the arse?
Then ill try and get the clutch bits in place before dropping the engine in.
The VN 304 already has extractors so Im hoping theyll fit in the bay and I can avoid having to get pacemakers...
The donor VN Im using already has p/steering and air con. My VH does too so Ill hopefully only need to redo the hoses.
Also the dellow crossmembers dont seem to get a good rap.. Ive heard you can use a trimatic one and just slot the holes out a bit.. Anyone done that?
Getting a complete new loom sounds sensible too.
Thanks a lot for the replies.
Personally I wouldn't bother rooting around with the pedals, plus god knows what it'd do to the structural integrity of it, shouldn't be too hard to get a manual one tho, not sure if a 6cyl one is the same, but that's all I'm using and it's ok so far..
I've heard the same about the crossmember, I've got one that I've made up for now, just for fitting purposes but intend on doing it the trimatic way in a couple of weeks so will let you know how it goes.
I've got the standard hsv extractors on mine and they fit fine, so you "should" be right if your using all the vn bits up the front.
Speedo is another issue to tackle, I ended up just using a autometer electronic jobbie, was too much rooting around to get the cable system going plus I'm planning on ditching the stock gauges eventually, so something to think about.
Sounds like you've done your reading tho.
In regards to the Intermediate shaft, is it the Power steer VL one or non power steer? As i am doing my research also for my V6 conversion into my VK and i have read mixed results in that respect.
Donor Car is a VP ute so i will be using its whole front end K-Frame and suspension with my Vk springs.
The 6 cylinder pedal box will work but the pedal travel is too long - you'll end up with a very light clutch pedal that's difficult to use. Ideally use a VB-VK V8 pedal box but I managed to modify the hook end of mine to alter the ratio to suit a bit better.
VL power steer intermediate shaft will work, I've heard that some (but definitely not all) VN intermediate shafts are the same anyway. If you've got little hands you don't need to remove the steering column.
I made a cross member for the T5 into VK using the VN rubber mounts, I wouldn't like to slot the Trimatic one as you'd be just about right at the edge of it and its not the right height unless you want to change the rubber mount either. (I'm guessing that the V8 T5 sits in the same place as the V6 one, I think so)
From memory the V8 T5 sit a little further back and the plate riveted on the tunnel has to be modified slightly to make the Gearstick be able to select 2 4 and rev.Somebody will have to verify.
^ That's exactly how the V6 one differs
my t5 doesnt touch on second and fourth.
t5 x member fits you just have to elong the mountoing holes so they are oval.
agree with the 6cyl pedal box its sloppy as hell i brought a vh pedal box from a 6cyl and its crap now got to source a v8 one
Gday Guys.
Got both engines out of the Vn and VH. Have just swapped the K frames out, using a VN k frame and lower control arms and my original VH shock towers and have the VL shaft to run into the VN steering rack. Have also just removed the auto pedal box and put in the V8 manual setup.. (that was fun...) and connected up the clutch, brake lines and accelerator. And ive run the ECU through the firewall. Phew.. Almost time to get the 304 in.
So now Im lookin at gearbox stuff. Ive rewired the wires that were running into the T bar shifter. But can anyone tell me the best way to go about sorting out the speedo bits. I was going to get an inline pulse convertor to attach between the gearbox and cable. But what do i do with the sensor wiring that ran into the VNs dash and loom and ultimately back into the ECU? Ive searched the site but cant find anything definitive.. Any info would be great. otherwise ill just leave it to the professionals to sort out.
Also how did the cross member above work out for you? It looks the goods. i was thinking of getting something like that made up. Is it the right dimensions? ie height?
Cheers.
Looking at doing the 5.0 into vk myself, abouth using the vn k frame will this widen the front whel base the same as using the vn diff will? Wondering as my calais is sitting rather low an have issues with tyres on inner gaurds as it us
Yes works fine for me, height was never an issue as the drivers side mount of the VN cross member I cut up is the same as VK so I could work to that, its just the side that goes up around the cat converter recess in the floor that differs. It is for a V6 not V8, but going by others' comments above it sounds like the position is the same.Originally Posted by hainzy
No, the VN front end is the same as the VK one
Mate, do yourself a favour and ditch the cable clutch setup. If you use a heavy duty clutch, you will need to start going to the gym to be able to put up with it in round town stop start traffic.
I have fitted VL 6cyl hyd master cylinders and pedal boxes straight into all of my early Comm's without any trouble and they are silky smooth and light as.
What efi tank is best to use? Does it have to be vl or will vn+ also fit? And jus out of curiosity why is the change over needed?
Vl pedal box in vh commodore
Does vl pedal box bolt straight in or do i have to gety handy with angle grinder.
Thanks
THe VL to VS fueltanks all fit. The Vn -Vs tanks have a flexible filler hose connection to the tank. Just remove the filler pipe and cut about 40mm out of it to fit. The Vl tank has an external pump the VN to VS are internal fuel pumps.
THe VL pedal box bolt straight in. Not sure how the slave cylinder would work.
