hey all...
ive read just about every forum i could find on VK VIN numebrs, but none can answer my question.

i was just wondering if the BT1 VK's VIN number will indicate that it is a geniune BT1.

if that makes sence.....

i am looking at upgrading to a VK, and i would like the BT1, i know what to look for in the interior, ie; map pockets in doors, screw holes in passanger A pillar, round spedo, rear brake discs..... but i just wanted to know if the VIN number would tell the story a whole lot easier.

thanks peoples..
regards, vincent

Well i think that on the build plate it will state say 8VK69-BT1. Thats all they have to say its a BT1, nothing on the VIN numbers.
Hope this helps you out a bit

ok, now im confused.... i just went to see the VK.... it is white..... has HDT wheels, the holes in the passanger A pillar, Map pockets in doors, rear ash trays, rear disc brakes, different roof light. it also has a couple of spare holes in the fire wall. and the owner said that the BT1's had extra torsion bars on the chassis.

but only problem, there was no BT1 stamped anywhere on any of the plates...

i am looking at buying this car, but firstly dont know if it is a genuine BT1. also, when we drove it, under heavy acceleration, the whole cabin filled up with smoke..... from oil touching the exhaust.... big problem?

finally, the owner said the car originally had HDT heads on it, but they shat themselves and he had to change them..... after we drove the car, there was coolant dripping from the centre of the "V" at the front of the engine.

the clutch was ridiculously hard to push down, but he claimed that was cos it has a heavy duty cluth installed, but i didnt think that would make such a difference. gearbox was a T5.

the body was straight as...and paint was really clean to.

any advise or info would be much appreciated....

Umm hmmm well can you post up details on the build plate?, like model code, engine code, trans code and diff code. Also try and get the engine number, that might be handy
Also how different was the roof light?.
Hmm this VK your looking at could be a 134 pack.

bigg_vin · #5 18-02-2006, 08:33 PM

what is a 134 pack?

the roof light was chrome, with a large center light that came on witht he doors, and two seperate spot lights with black switches... hope that helpls.

i did not write down any numbers from the plates.... but i remember looking at them and thinking that they were pretty stock standard.

apparantly the clutch was hard cos the cable needs replacment.

also, i thought the speedos int eh BT1's were different. this one went to 180, and had a round circle with the square border..... speedo did not work anyways...it was all over the place.....

thanks again.

134 pack usually is a SL model with 308, M21 combo, i *think* they also have a V5H upgrade motor, the same motor used in the VK SS from HDT.
That interior light is mostly on BT1's, its the same on the Calais models.
The BT1 speedos are mostly the same as on normal VKs, but with measurements in between the numbers. Plus yes are rounded.

i remember seeing M21 on the plate... what is it? is it any good? are they rare or not worth the hastle? i dont know if it is a 308 or 304, how can i tell? thanks

SL/ENUT · #8 19-02-2006, 09:09 AM

M21 is the close ratio Holden design and built 4 speed manual gearbox, not to bad but hate a flogging. These gearboxes are mostly used behind all 304/308s in the VB-VKs.
Now on the build plate if it says "Engine L31" thats a 308 but if it says "Engine LV2" thats the 304. Also check the engine number on the block.The number is stamped on the left side motor at the front.

bigg_vin · #9 19-02-2006, 11:49 AM

it said L31. cant remember the engine number. gear box has been changed to a T5 anyways, cos he said that 2nd gear stuffed up.

so were 134 models rare?

SL/ENUT · #10 19-02-2006, 12:59 PM

Well i don't have any figures on how many 134 packs was built but they would be worth getting anyway.
L31 ahhh a black 308. Still this VK might be worth to get.

bigg_vin · #11 19-02-2006, 01:43 PM

so im guessing the 304 is better than the 308?

if i can get it cheap, it is probably worth it yeah? do you have any idea what they are worth? he was originally asking 6500, but he said to make him an offer.....

thanks for the help

SL/ENUT · #12 19-02-2006, 01:52 PM

Well if its a factory 308 manual then make him an offer, although $6500 ain't to bad. Any VB-VK 5litre manual usually go for a high figure.

And the 304 is a little bit better than the 308, especially the VL 304, has the same valve size as the L34 head.

bigg_vin · #13 19-02-2006, 04:21 PM

i just spoke to him and he says its a 304. but he has had theheads changed..... he said that originally they said HDT on the heads.

did BT1's come out in 304 and 308? this car is a 1984 model....

thanks

SL/ENUT · #14 19-02-2006, 06:15 PM

The came out in both. Since the one your looking at is a 1984 built VK this originally would have had a 308, half way in 1985 the motors changed to 304 for Group A racing.
Hmmm sounds like the heads could be the A9L spec ones. Often ppl will say that B cast heads are HDT ones but they are a factory Holden performance head.
