Joe McNicol hates people complimenting him on all the chrome work
under his bonnet.
He
also has a passionate dislike for VL Commodores and laughs at the number of restored
Commodores with engine or sound packages worth more than the actual car.
But lets not be too hard on Joe! Hes a top bloke as it happens and is
totally obsessed (with a capital O) about his 99 model VT GTS.
So youd think Joe would love all the praise for that chrome in the engine bay -
except that not one component under the bonnet has been chromed. Take a good look at the
photo below - yep, its all highly buffed alloy!
Says Joe; "Let me tell anyone who is thinking about the polished alloy look, that
it is 100 times harder than you think and will take 1000 times longer to achieve than if
you just went out, bought the parts and had them chromed!"
The detailing didnt start and finish under the bonnet with Joes GTS
however, as a few key undercarriage components have been given the full treatment as well.
But lets go back to where it all began.
A long-term love of the GTS
"I think Ive always been a fan of the GTS moniker ever since the first
GTS Monaro," stated Joe.
"The VT Series 1 is obviously the pinnacle of Holdens GTS lineage and I
simply had to have one."
It has to be said that Joe isnt a big fan of the present Series II GTS and all
because of that Chevy engine.
"If you were to give me a free Chevy motor I wouldnt put it in my car.... I
wouldnt want to have to wear my baseball cap backwards to drive a car and you can
surmise from that what you want!"
As you can gather from the
opening paragraphs, Joe has a point in that a majority of modified Commodores start out as
wrecks, or as base models with nothing very exciting. True, many of them turn into works
of art, but how about starting with something perfect or exclusive in the first place?
Surely a car like this, once modified, would be something very special indeed
Right from the outset therefore, Joe wanted to use a standard GTS to create
a very special car. Still, dont go thinking that his GTS is simply a cosmetic
wonderment.
That engine may be detailed to the max (and well look at that aspect a
little later on), yet its certainly not the motor that the car left HSV with.
While Joe did buy the car brand new and added a mere 9,800 kilometres to the original
engine, a brand new out of the crate 5.7-litre GM block was the starting point for the
motor that now lives under the bonnet.
Thats right folks, Joe rejected the barely run in original block for his project!
No tolerance, no corner-cutting
To build his engine, Joe brought Perths renowned Southside Engine Centre in
on the act, with a bloke named Craig performing all manner of preparation work on that
brand new lump of metal.
"I think a more apt name for Craig is 0% tolerance," quipped Joe.
"If its not 101% perfect then Craig isnt happy."
Operations performed on the block included the usual cleaning, crack testing and
decking, but line boring was probably the most important task.
The bore is now 20 thou oversize too, producing a capacity closer to 370ci.
Then there are the splayed and shot peened 4-bolt
main caps with ARP bolts, making for one very serious bottom end indeed.
When it came to the long thing with big lumpy bits, a balanced, knife edged, shot
peened and nitrided Crankshaft Rebuilders crank was chosen - considered by most to be the
best money can buy.
Between the crank and those JE slugs live eight 6" Lunati rods and it goes without
saying that the entire bottom end has been fully balanced.
The top end begins with Dave Bennet Dash 9 heads, ported for 612Hp no less.
"Wayne, the Cylinder head guru at Southside, has had a lot of experience with
these heads in race boats, sprint cars and the drag racing scene," explained Joe.
Internally, the heads carry a smorgasbord of quality valve gear, which is detailed in
the Nuts`nBolts at the end of this story. Nonetheless, one valve train component
alone is critical to the performance of this engine.
"Selecting a camshaft was the toughest job of the lot," conceded Joe.
"Obviously, I wanted to be able to drive the car on the street, but still have
shit loads of power in the higher rev range - above normal driving conditions."
Crossing the border
Chris, from Crane in South Australia, was soon involved in the project together
with Southsides proprietor Graham Ellis.
Together, they chose a Crane timing stick offering a maximum lift of 598 thou
with maximum duration of 252 degrees. Those are certainly impressive figures and its
perhaps not surprising that the cam works to its optimum between 3,600rpm and the rev
limit of 7,400rpm.
Getting off the line is not a problem though, as the cam still has very strong torque
characteristics at low revs.
On the induction front meanwhile, Joe opted for a product that we dont see a lot
of, but which has a solid reputation.
"Id read heaps about the Starr Performance manifolds on e-mail newsgroups
and that, so eventually I called Peter Starr and told him what I was up to," said
Joe.
Peter
did the right thing and sent Joe a bucket load of info, including flow figures as well as
before and after dyno examples.
Needless to say, one of Peter Starrs manifolds was soon winging its way west and
when bolted onto the GTSs original motor produced a 36Hp increase at the rear wheels
all by itself - impressive.
Fuel is introduced to the equation by eight high volume Bosch squirters and the whole
deal controlled by the cars original computer.
But yes, youre right, the cars electronics have been re-programmed.
Over to you again, Joe.
" Lachlan at Chiptorque was given all the engine specs and although he said he
hadnt made a program for such a big cam before, he was able to come up with a custom
program to get the car run in.
"Were now onto Lachlans fourth chip actually, so hes following
the progress of the car very closely and will in fact be coming to Perth soon for some
intensive hands on development."
Prints on the polishing
One other individual who was very hands on with this project was Peter Thompson -
"One of the best HSV mechanics here in Perth and a true friend."
Peter spent many hours on the engine towards the end of the project, although he did
make one terrible mistake.
"Hes the only mechanic in the world who can put finger prints on the
polished bits under the bonnet while changing the back wheel..." quips Joe.
On the exhaust front meanwhile, Genie 1 ¾" primaries lead into a custom
4-into-2-into-1 system each side that was hand crafted in stainless steel by Tony at Genie
in Myaree.
Theres a single high flow cat on each side too, before a single 3"
system takes the waste gases right out back to a highly polished Genie muffler and
resonator.
The full exhaust system is marvellous to behold, yet theres plenty of other
features under the floor of this GTS that attack the eyeballs when the cars up on a
hoist.
Big things, little things
The car carries a brand new auto transmission built up by Rod at Carousel Autos,
with an adjustable shift kit and a few other trick bits. The transmission sump has been
polished and the bits in-between the cooling fins painted red by a lifelong friend.
"Ken and I went to primary school together back in Victoria, so weve been
mates for a very long time," explained Joe. "It took him a full week to do that
tranny sump!"
Oh, and in case youre wondering, Ken powder coated the entire bottom surface of
the tranny sump, then buffed across it to remove the paint from the tops of the raised
fins.
Even more spectacular is that diff housing from WH Diffs, and no, it hasnt
been chromed!
And of course, all of these highly cosmetic pieces carry plenty of trick internal
parts.
Auto Flight Engineering - the people behind Dominator stall converters - took care of
the stall converter (surprise, surprise!), while the stall speed has been raised to
2,700rpm.
"Dominator are the most widely used converters in Australia and renowned to be the
best drag racing converters available, its that simple." stated Joe.
"In any case, no-one in Perth could make a stall converter for the 4L60E automatic
gearbox in my GTS."
The point here, folks, is that letter E at the end of the 4L60 E tag.
Explained Joe; "The E means its an Electronic box, but it was
too new and no one had made a suitable stall converter that also had electronic lock up in
4th gear."
When we asked Joe why he decided not to convert to a manual gearbox, he replied that
getting a manual gearbox and clutch to handle the sort of power he was chasing in a VT was
something no one could advise him on.
"Besides, I dont think a manual could shift as fast as this auto
anyway," says Joe.
"And in any case, Id prefer to keep my left hand free for more adventurous
tasks that may be occupying the passenger seat!"
From the tranny, the cars original tailshaft leads into one of the most amazing
diffs youre ever likely to see.
"I discovered WH Diffs in Street Commodores magazine, would you believe, then
asked around and eventually spoke to Wally himself at WH," said Joe.
End result is a manganese alloy housing that bolted straight up to the GTS with no,
repeat no, modifications to the car whatsoever. If you think thats good, then
consider that the package retains the GTS ABS braking system and IRS rear end.
Unlike the Hydratrack diff fitted to the vehicle ex-factory, the WH diff is
configured for dual wheel lockup and so wont "leave one wheel behind."
Oh, and before we forget, the gears are Ford 9"and the axles are custom made 31
spline pieces allowing for superior strength and an almost endless range of ratios,
although for now its 3.5: 1
Its worth noting too that the diff doesnt have to be removed from the
car to change the internal gearing. With the driveshaft disconnected, the front of the
diff can be unbolted and the gears changed over.
Staying with the undercarriage for a moment, Joe has opted for the HSV premium brake
package. "Theyre just totally awesome, I cant rave enough about
them."
Suspension duties are taken care of by stock GTS componentts, except for the addition
of an anti camber kit at the rear end courtesy of Gmac Autos in Myaree.
Now that weve proven the worth of Joes mechanical refinements to his GTS,
lets get back to the cosmetics and dive under that bonnet once more.
But wait, theres more polishing, that is!
For those who still dont believe that all those shiny bits are hand
polished, heres a full list; Starter motor shield, water pump, alternator housing, ,
alternator bracket, timing cover, throttle body, inlet manifold, Air conditioning pipes,
head faces , spark plug covers , ABS Unit , transmission sump and diff,
Some other little trick bits you will see under the bonnet are the hand machined alloy
pulleys, strut tower covers and dip stick grip, stainless steel oil filler cap, and full
race harmonic balancer.
And if you still think hand polishing like this would be a relatively easy task,
consider that it took Joe five weeks to do the water pump and an amazing three months to
reach a point of satisfaction with that Starr inlet manifold!
The process began with wet and dry sandpaper, 300 grade to begin with before working
through 600 and 1200 grade. Then it was out with the Autosol and cotton wool buds.
As you might expect with a vehicle like this, there are numerous other small touches
that required intensive labour.
For one thing, Joe has lost count of all the stainless steel bolts, nuts
and washers hes added - as indeed he has lost count of the hours spent cutting the
bolts to the required and exact lengths.
Its hard to know how to sum up a car like this, so perhaps well leave that
to the owner.
"This car wasnt built to a budget, but to specifications with the aim of not
cutting any corners
"
Well, we certainly cant see any rough edges!
