This is funny. People are listening to so much BS about HSVs...

The Ford BOSS V8 is Quad-cam (DOHC per bank). The Falcon V8 doesn't put out more power, but does have shite-loads more torque (40Nm).

It's an iron-block, truck bottom end with Aussie designed Mustang 4.6Litre V8 heads.

Holden HAVE been able to get the tuning right (more than the Americans) but have restricted (retarded) the tune of the Gen III for local conditions, emissions, and economy. Oh, and the fact that most Aussies can't drive for sh!t.

The reason the C4B (300kW) V8 is made by Callaway is for cost. they use crate motors for the 400hp GTS' while the 255/260/285kW cars are ordinary SS engines with:

New exhaust (not headers) with cat and muffler and tip

New tune on ECU. (They go through a computer terminal that allows them to choose how much power the ECU tells the engine to make. Ie: they open up different "hidden" maps in the ECU like 290kW, 330kW, etc)

Some more cosmetic bits.

Horses for courses. Skyline's a different car doing different job. I'm not suggesting we join hands and sing songs of praise but respect your fellow petrol heads' rides and they'll respect yours. If you don't like that, catch a bus.

Erm, yes i do have a clue about that. Why don't you drive a ZO6 C5 Vette against a 300kW GTS Coupe over a rough road. The Vette will be left scuttle-shaking all over the tarmac.

Holden got the tune right cause the Americans adopted the specs for their engines in 2001. You obviously have no idea about the factory Delco engine management. :D

As for Trans-Am/Z28/SS Camaro/GS/Mustang good luck. The Cobra R is the only one that could be the locals but have you driven one? The build quality is non-existent and a blind demented kid could've designed a better looking car

Im not going 2 reply as this is a thread about Skyline and Hsv, make a thread and i will talk 2 u about that stuff

This is too much fun:D

On the other hand, the 5.4L V8 in the BA falcon was built in australia (still using mostly american parts though) but still a much better engine as it has DOHC.

Sorry you are wrong there. Having DOHC does not make an engine good, just as pushrods dont make engines bad.

As someone said the Boss engine is based on a truck bottom end with Mustang heads. At 6,000rpm the thing has piston speeds within a couple m/s of an F1 engine (ie. cant really rev any harder) So is never going to make any decent power without forced induction.

And rule out turbos as the width of the engine means there is no space, so really if you want more power from one all you can do is supercharge it.

Cams will be almost a waste of time as the engine cant rev any harder, and bloody expensive as you will need 4 cams ($$$$)

I can guarantee that if you go chasing power out of the GenIII or Boss 5.4L, the Chev will leave it for dead.

That said Ford are bringing out a blown 5.4L, but these Boss engines do not have near the power potential in the hands of the aftermarket tuner.

Well thats my thoughts anyway.

New tune on ECU. (They go through a computer terminal that allows them to choose how much power the ECU tells the engine to make. Ie: they open up different "hidden" maps in the ECU like 290kW, 330kW, etc)  

LOL!

if it was only that easy.

imagine

wake up in the morning and say ok i feel like 800hp today, so u type in 800hp on the computer and away you go! :bahaha:

Actually its true with many of the modern engines. The tune dictates the power of the engine, conservative ignition, plenty of fuel, crappy exhausts/inlets are the differences between a family of engines, not the actual engine internals.

Not only on local Ford and Holdens but on Audi/VW/Skodas etc etc who rely on the same engine families

bear in mind that the majority of people who buy HSVs and GTs don't go looking to modify them, so who cares if u can't get much more out of a 290kw GT?

on that topic tho, i work at a ford dealer and their currently fitting a supercharger kit, that should allow the engine to produce around 400kws....

use are all saying that hsv are like 50,000 compared to a gtst

have use actually been ine one before???

i truly doubt every cent of that 50,000 has gone towards its motor...... one of my mates has a new r8 and fark me its a pleasure to sit in with th einterior it has.

shits all over the standard r33 gtst thats 100% for sure ... i cant believe dick heads like use say shit like this all day long... its a ****en classy car.. does 13.8 stock

interior is unreal and yet use still bag da **** out of it...

personally i think a hsv is alot more classier then a r33 gtst

I think we have to remember that a car has more point's to it than just 1/4 mile time's....

Sure a GTR is a fast car with awsome handeling.... But the seat's and the tough suspension would DEFINATELY give you a sore A$$ and back by the time you made it to Brisbane....

Commodore seat's are comfortable... and matched perfectly to the "Average" Aussie body and weight... with plenty of lower back support and leg support. The dash instruments are lit well and 100 kmph sit's right at the top of the arc so it is easy to see....

There a lot of little thing' s that come in to play, Torque is plenty low down where you need it most..... not all car's need to hammer to 9,000 rpm to make max power when over taking (although the scream when overtaking is fun :() They can fit 4 - 5 people in comfort and still haull A$$ ..... They New VY series II HSV's look awsome.... i really like that colour (looks similer to the midnight purple in the GTR) and Skaife really give's it a hammering.

When i'm 50... i hope to have a nice HSV..... and an awsome TEAM of GTR's running in the PRO CAR series....

Loz

I have driven a friend's new XR8 and it is a very nice car. I would keep it if someone gave me one but I wouldn't buy one myself unless I could still afford to keep the Skyline as my weekend car, because it's just too agricultural. It feels like you're driving a big hovercraft (although it does handle pretty well for its size) and even though there's 260kw on tap it just doesn't feel fast because of the huge weight of the thing.

Because my friends (married couple) use it as a work car it's not going to get much if anything in the way of performance mods. But still, it's faster than the vanilla 6 cylinder versions of Commodores/Falcons.

(these comments made because I think that the BA XR8 would be very similar to a current HSV)

have u been in one?

have u seen the quality of there interior

its like sitting in a big leather couch

HSV isnt factory produced holden..

HSV grab some cars of the production line and do things to them hence HSV enhanced...

there sexy cars..

perhaps you should drive in way...

made my skyline interior look like mud thats 100% sure..

100% kicks da shit out of any jap interior...

    • No, I refuse to buy their cheap ass crap! I do need to order a bunch of different nuts/bolts to refill my nut/bolt wall though. Maybe you could go for a walk through Bunnings for me? (Or send me some stuff from your work? )   I really struggle to work out how the US standardised to Metric in what the 70s or 80s, and yet, half a century later, there's been little done to actually bring it into fruition. It truly baffles me    On the whole Fastenal thing, I went reading their site (My god they sell a lot of varied stuff!), and it seems like it really depends what store you're near if you can walk in and just grab a few small things, or if that branch is primarily distribution with only a small window of "counter time" available (if at all). That definitely makes it harder, as move locations and it drastically changes your ability for success   For things like your M6x1.0, if you want to work on your own Skyline, and you also have a "home workshop" I'd recommend setting yourself up a small Nut/Bolt wall/section. It doesn't even need to be big at all. Most things depending on the diameter, will be a specific pitch, like the M6x1, M5x0.7 etc. Bigger bolts is mostly 1.5, except for a small number of things and that will come down to torque. From memory bolts for the brake calipers (and other things that need a lot of torque) will end up being a 1.25mm pitch. Save up a few dollars, and order a range of nuts/bolts. If you want to minimise cost a little, buy something like M6 x 40, and M6x70mm (1mm pitch) in both. In addition, buy yourself an M6x1mm thread chaser. That way you have long bolts that you can cut down to size, and then chase the threads out. Funnily enough, I find what I'd pay here for ordering 5 bolts, I can pay about 50% more and you'll get 100 of them.   If that doesn't quite work out due to space / ability to buy plenty up front, then each time you need some bolts, order 100 of what ever you're getting. Put them in clearly marked containers. Over a few years, you'll acquire plenty of different sizes, and will end up ordering less and less. And the cost for 100 bolts won't be much more than you paid for your 5 you needed to order anyway  Just takes a little planning ahead, by investigating what nuts/bolts you'll need, and ordering them before doing the job.     Edit: If it's also primarily for working on just the Skyline, for some reason my brain is screaming that at some point, either Nissan, Nismo, (Or possibly a third party) was selling a "kit" of every nut and bolt in a Skyline, purely for people restoring/rebuilding. It'd likely be quite expensive, but would give you every/any nut/bolt you need for stock/factory things. I'm not sure if it's still available, or even if it actually fully came to market, it's just something niggling in the back of my brain that you could look into further if that sort of thing interested you? (It might have been for the R32 GTR or something specifically too, and not just any Skyline)
    • 90lb/min @ 20psi is wonderful, not so much of a problem with the G35-1050's compressor efficiency (aside from how bad they roll back at higher pressure ratios).  The issue is more to do with the turbine's flow, which is why I'm not sold on going an even higher flowing compressor with the same turbine.  I'd say go back over Motive DVD's testing of the G35 1050 and Hawkins's comments regarding exhaust back pressure issues with it, I'd need to go back but I have in my head he went to the biggest hotside and ended up sacrificing a lot of spool (so it ended up behaving like a bigger turbo) and still had EMAP issues.  I've heard various other experiences along the lines of that. At this stage at least I rate all I've seen about Xonas (for transparency I've not used one directly, but I have spoke plenty with people who have) to have low exhaust restriction for the response they offer for any given setup - basically they allow the engine to breathe, which is good for the engine and makes making power a lot easier.  You arguably don't have to even push quite the same amount of airflow through an engine to make the same power if you don't have the bum plugged up with exhaust gas struggling to escape the engine due to an underflowing turbine.   In terms of reliability, to be fair I've had great luck with Garrett turbos as well - my GT3076R lasted forever, then I sold it and the next owner had no issues, then that car got sold and it was still going strong last I ever heard about it.  The trick is with the old GT-series turbos the compressors etc were no way near as efficient as what we have these days, it was almost hard to push them into severe overspeed situations without having a boost leak or something - and that is what often starts the failure situation.    In terms of your G35 I'm pretty sure you're running yours within sensible limits, something people with Xonas and Precision turbos aren't often so inclined to do.  The "compressor maps" are "Joe blogs ran 45psi through his 6466 so I can do the same" and built their setup to send it to the moon.  I've seen EMAP and compressor speed data where people have actually set that stuff up on Precisions and Xonas which have been run hard and the comp speed numbers are very very exciting at times - like I've seen 76mm Precisions run at rpm that you ideally shouldn't run a G35 1050 lol.   I know people who have run G-series Garretts hard and hard a failure, then replaced them with Pulsar turbos as a cheap "get it going" stop gap with the intent of doing a proper upgrade when THAT fails... and are still running the same thing.   Like anything, ymmv and it's not always to do with the quality or trustworthiness of said product. I've been provided with a bunch of compressor maps for Turbosmart turbos and will update my list based off that, they could prove to interesting reading and an interesting alternative as well.
    • Just cage it, call it a race car, and then fall in love with the chirp chirps through pit area!   Also, this is coming from someone with a completely locked diff...
    • I still have an old R32R left over from when they were a thing in the early 2000's. It was, for its time, done about right. But its time was 20 years ago.  I did try and update it a while back but it was cruelled by a (recommended) muppet of a tuna who couldnt tell his MAP from his TPS. The original spec was: Power FC, 700cc Sards, Nismo pump, 2860-5's, cams (Basically Poncam A's), Z32 AFM's and a half sorted oiling system. Thereabouts 430rwhp irrespective of what was done. So, yeah, very 1990's. I eventually got sick of it not being very refined and bought a Link G4 PNP with some 1000cc Bosch injectors. This was tuned badly and I put the car in the shed for a few years whilst I sulked and went and did other things. Ive come around to the idea of getting it going again so it has a new gearbox installed and some other minor things in the planning. So my questions are, variously (In the context of keeping the Link) What other sensors should I be running eg It has no wideband on it at the moment, nor fuel pressure. $? Is it worth chucking the old ignition system (ignitors etc) for new ignition coils? $2k? Cam/crank angle sensors? Can keep the aircon? $? Anything else? Sorry to launch another what should I do with my car thread but, you know, what should I do with my car? Random photo for historical context.
    • If you think that's harsh, go experience a KAAZ 🥲 Thoughts and prayers for Dose. I had mine modified by a diff shop to make it less brutal, no idea what they did but it's not as brutal as before. The Asian in me was being tight before and went KAAZ instead of a Nismo, lesson learned.
