Something to keep me sane!!

Post by Sammy »

Well as alot of you know i got flooded out in June long weekend storms ... since then the FB Ute has been in storage at my brothers place and i haven't had alot to do on cars as a result. Another car i had unregistered was my LH Torana, which was originally taken off the road because it needed new suspension, gearbox, brakes the list goes on.

So when we had to leave our flooded house i had to decide, fix torana or find somewhere to store it ... with the latter not really a viable option and us needing a second car (VR Commodore was written off in flood) i decided to use the $5k payout from the VR and get the Torana back on the road.

So began the quickest project i have ever done!!

Plan was pretty simple:
* rebuild motor
* rebuild and fit T700 from VN Commodore (stage 2 shift kit)
* commodore brakes (vl turbo/vp v8 brakes)
* new shocks all round
* tidy up a few other little things

*** get it all engineer approved ***

ok this is the motor i had in the Torana before which was dynoed at 140rwhp ... its been rebuilt with more unleaded friendly compression ratio (it was flooded, that was the main reason for the rebuild) you can see in this one the CRS adaptor plate to mate the box to the engine, very nice kit i must say.
Image

also had to do some mods to the extractors to clear the gearbox, more so the linkages for the shifter but yeah, this is what i came up with, originally both pipes went down side by side whereas the torana needs one above the other to clear the crossmember.
Image

as can be seen here
Image

also quickly whipped up a gearbox crossmember to keep the engineer happy.
Image

bit of bling (which works unreal i might ad)
Image

while i was at it i resolved the suspension issues
Image

this is a shit picture, but as you can see, i have the commodore rear discs on there, i swapped them side to side to get the calipers at the front of the diff otherwise the calipers would hit on the shocks ... so to do that i left the handbrake mechs on their original sides and then re-located the handbrake holding bracket to get it to be at the front.
Image

i then made these brackets to mount the cable at the front and screwed them to the floor of the car
Image

i mounted them such that they would fit onto the original torana handbrake cable, this only just fitted with the use of the longer wagon cable!! (i love it when you can use off the shelf parts down the track)
Image

the finished product ... and yes i will be cleaning the red paint off.
Image

drivers side
Image

and heres one of the fronts ... these had been done for quite a while now ... (before the floods)
Image

as im sure some of you know, the T700 normally has a speed sensor screwed to the side of the box to tell the speedo and ecu what speed you are doing ... so when i put the gearbox in the torana the conversion kit came with a cable to suit my needs which works fine except that i had to put smaller tyres on the car compared to the stock commodore diameter otherwise they'd scrape on the guards ... so this created the problem that at 100kms the speedo was reading 120km .... which is not really bad as far as speeding goes but its really hard for anyone to just jump in the car and know whats happening.

So with that in mind aswell as the fact i need the speed sensor for running the VN ecu in the car (another project im working on) decided me to bite the bullet and outlay $350 for a VDO electronic speedo unit to resolve the problems.

so with a bit of cutting and modifying of the stock dash cluster i was able to easily fit it in there
Image

a few mods to the wiring for lights etc and she was all ready to go in the car
Image

only thing was that the original speedo has the blinkers and high beam lights as part of the speedo face, so i had to put some extra lights in to keep these on the dash .... you can see the two green ones for the blinkers and the blue one on the bottom right of the cluster is for the high beam
Image

all in all very happy, it was easy to calibrate and at 100kms on the speedo the gps is reading 100.5km so i'm stoked!
thats probably the most of it ... theres pics at:

oh and this is the finished product....

torana---- maybe you can enter that as ek modified an the nats?

Its sorta weird seeing some thing that most of us would refer to as a parts car for our fb/eks, being restored on this site.... :lol:

Mate i reckon she be a hell of a lot more fun then driving the commo, so as far as im concerned, the big fella upstairs may of just done you a favour, so count your blessings buddy, and hope he doesnt have to flood the torana now to get you to finish that ute. :wink: :wink:

hahahahyour persistant Mal, i'll give you that!

on a serious note though, i just the other day submitted my plans for the new shed to council for approval so hopefully before to long i'll be in business and then i might be able to work that quickly on the ute!

retro, your dead right, the torana shits all over the commodore in everyway other than fuel economy hahaha but the vk efi has made it pretty reasonable for what it is so im happy to pay a bit extra!

actually i'd prefer the a/c and demister in the commodore but thats it :lol:

shoulda put a V6 in, conversion kits from gardener a reasonably cheap, V6 and autos are a dime a dozen then you'de have the economy you speak of and plenty of room for air con
yor vk motor must be thirsty or yor commodore was extraordinarilly good on fuel my old vn and my new vt both return 10 litre per 100k's which i think is good and the old carbied 308 in the van with no O/D gets 15-16 litres per 100
been sorta thinking of doing the same as a seller can get a real good LH six/auto with air for $350 got a vn down the back (motor/box) so $1500 for conversion kit and a couple of days work owes me say $2500 going but unreg should be worth more than that i'de like to think :?

i have been getting about 12-14L per 100kms, but i don't really drive it economically much :) the biggest killer is it needs 98 octane fuel.

i have thought about the V6 and eventually probably will do it, but for the time being the 202 is a good trusty beast ..... as it stands with the toranas current performance specs if i dropped a stock v6 in it i reckon it would be a very close race between the 202 and the stock v6 .... so that means for it to be worth it i need to get a v6 worked and then worry about the conversion :)

i have a few v6's in various states in the storage cupboard but i want to get the vn efi on the 202 and working sweet before i go v6 though, because i do 120kms each day so it will be perfect for tuning and logging data! and once i have mastered it on the 202 i will have another home for that setup and it will also give me a head start on tuning a worked v6!!

Sammy.

god that 202 must go i think the commodores i have/had would beat my van
but yor torana was already set up for that motor wasn't it, and it's only a quicky to run around in

yeah it doesn't go too bad, i've spent alot of time developing this engine to be more streetable and economical etc and its pretty good, only thing holding it back now is you are so limited with the VK EFI in adjustments .... plus it doesn't control the spark which is another big bonus of the VN EFI.

The 202 is stock in this car (well the red motor version anyways) so as far as the engine went it was just a matter of a few minor mods for fuel and wiring .... but the main change is just the gearbox crossmember for the T700 ..... all of these mods though would bolt straight into another torana.

going off rough figures i think i worked out i got about 10hp more than a stock vn commodore but then they weigh about 1400kg and the torana after all the mods was weighed at 1240kg so its got a fair advantage there...

the head i have on this engine is kinda my pride and joy, its got alot of history with it and alot of things that suprise people.

originally a guy dad knows had a torana stock car and it was around the time the wb/vc commodore was just new and he wanted to go for the blue motor head but couldn't find any at the wreckers, so he went straight to holden and got a spankers new head (don't you wish you could do that now!) then took it into an engine shop and got it worked over (lots of porting) machined for screw in studs and a hell of alot off the deck (stock chambers are 56cc's approx and mine are 44cc) .... so he punted that round the speedway for a while then dad bought it off him, got a bit more work done and changed a few things then put it on the motor that i now have.

It was a great head because it has adjustable rockers and uses stock sized valves (which suprises alot of people) but the rocker pivots broke and yella terra no longer made them, so i had to go for either roller rockers $400 or more or i had to find another option.

It was just by chance that i was looking through my parts and came across vn v6 rockers and they look very similar to the holden 6 ones .... so i set about modifying the rocker pivots from them and eventually with the use of 308 pushrods i got the rocker geometery right and all was dandy..... they are good in they are cheap, plenty around, and they are 1.65 ratio compared to the stock 1.5 ratio the 202 had normally.

for those that are interested .... this is on the left the vn v6 rocker, the pivot actually has the right size hole in it to suit the 3/8 screw in studs i had, and the right is the stock 202 rocker that i was using just with a different style pivot in it. You can see just by looking that the v6 rocker is a fair bit more meaty!
Image

the pivot i had was like the v6 one but it was alloy, and the v6 ones are steel ....

on the right is the stock vn v6 rocker, and on the left is the modified one, just got the grinder out and shortened the pivot :)
Image

and by using what turned out to be a stock 308 pushrod length i got the geometery perfect.
Image

stock 202 pushrod v's the shorter 308 pushrod
Image

and this is them all setup on the car ..... yes i had to do this on the car because i found the pivots broken once the engine was in the car and i had to drive it for a week or so before i got the vn v6 rocker solution.
Image

well i've babled on for long enough today better go and do some stuff before i have to leave work!

Sammy.

well this is what happens when you let your partner drive your car to work ;)

Image

in all honesty its probably the 12,000kms i've put on the axle that did it and she just happened to have it on the right day :)

im now starting to explore borg warner 28 spline diff options!

I knew there was a twist in that story somewhere. :lol:
Sorry Sammy just had to say it.

Good work on the rockers not many would of come up with the idea. Throwing longer ratios rockers on is a simple and effective way to increase the cam lift, without changing the cam and still maintain good idle.

thats alright mate i've been taking the piss out of my partner for snapping the axle any chance i get :)

your right about the rocker ratio, it ended up just being a bonus which i wasn't too worried about at the time, more just wanted to get something decent back on there but it makes a good mid range improvement in power compared to the stock ratio .....

i may have found a suitable borg warner diff option so i'll get some more info together and let you lot know because its something that should fit into the old holdens too ....

Sammy.

nope ... before the axle breakage it was a banjo lsd centre (fine spline) with a v8 yoke on the front and the axles are from a commodore borg warner and cut down and re-splined to suit the banjo. then it was just a matter of mixing and matching the rear disc bits left and right to get them to fit in ....

so now it looks like im going to be getting a borg warner, cut the tube ends off it and then put the torana tubes on the ends, this will then only leave the inner upper control arm mounts to be welded to the housing and it will be done.

once i have that done i can then measure the lengths i need for axles and then put an order in for some billet 28 spliners to suit.

then i will only need to get the tailshaft modified to have the commodore rear uni/yoke fitting on it which is a bit annoying as the current tailshaft was custom made in august for this setup!

anyways, like i was saying above, a possible option for old holden owners who want to get something like a commodore diff put in may be to use a nissan skyline r31 diff ..... it turns out these units have the same centres as commodores (albiet different ratios) and have 28 spline axles aswell ... the advantage of them is that the diff housing is apparently 9mm longer either side than the stock torana one (so i am told - have yet to confirm)

so if you wanted to, you could get the skyline diff, cut the mounts off and get old holden mounts put on it, then re-drill the axles and discs to suit whatever stud pattern you wanted. This would give you rear discs aswell as a strong diff and far more options in ratios and a newer more available diff. Also the hand brake works off the caliper i am told.

i was going to use this option but seeing how i have to get the torana control arm and spring mounts put on i figured that using the torana axle tube ends with the mounts on them already would be easier ... plus i have a spare vr commodore diff and a spare torana housing so i may aswell use them all up.

i am looking at making a jig to mount this all in to do the mods, then once i've done it i will be cutting down another vn diff i have for my partners EH project.

Sammy.

i'm going there today to get the photos off his camera and do some more work.

also i am waiting to hear back from council for approval of the shed which will house the ute .... so there are plenty of wheels in motion, its just all slow going!
