Vn Vp Vr Vs Vt 5L engines
Hi i recently purchased a series two vq statesman. I was wondering what the difference is in the early 5Li motors such as Vn to the Later ones such as Vt and Vs i knoe there is a considerable power difference liek 20kw or something where does this come from can anybody help.
VN

VP
Multipoint fuel injection. Engine management computer. 91 octane fuel. Breakerless high energy electronic ignition system.
Capacity: 4.987L
Induction: multi-point EFI

Maximum Power: 165kW @ 4400 RPM
Maximum Torque: 385Nm @ 3600 RPM
Redline/Cutout: RPM
VR
Multipoint, grouped fuel injection. Engine Control Module, or Powertrain Control Module (with auto trans.). Computer diagnostics. 91 octane fuel. Breakerless high energy electronic ignition system.
Capacity: 4.987L Induction: multi-point EFI Valvetrain: overhead valves, 2 valves/cylinder Bore x Stroke (mm): 102.0 x 77.0 Compression ratio: 8.4:1 Maximum Power: 165kW @ 4400 RPM Maximum Torque: 385Nm @ 3600 RPM Redline/Cutout: 5500 / 5600 RPM
VS
Multipoint fuel injection. Engine Control Module, or Powertrain Control Module (with auto trans.). Computer diagnostics. 91 octane fuel. Breakerless high energy electronic ignition system. Grouped fuel injection.
Cylinders: V8
Capacity: 4.987L
Bore x Stroke (mm): 102.0 x 77.0
Induction: Electronic grouped fuel injection.
Valvetrain: Overhead valves, pushrods, 2 valves / cylinder.
Compression ratio: 8.4 : 1
Maximum power: 165 kW @ 4400 RPM
Maximum torque: 385 Nm @ 3600 RPM
Redline / Cutout: 5500 / 5750 RPM
VT
'Hot wire' air mass metering. Sequential fuel injection. Engine management system. Computer diagnostics. Twin electric cooling fans. Stainless steel exhaust. High flow air cleaner. Low restriction dual exhaust. Breakerless high energy electronic ignition system. Knock-control sensor. Low friction technology.
Cylinders: V8
Capacity: 4.987L
Bore x Stroke (mm): 102.0 x 77.0
Induction: Electronic sequential fuel injection.
Valvetrain: Overhead valves, pushrods, 2 valves / cylinder.
Compression ratio: 8.8 : 1
Maximum power: 179 kW @ 4800 RPM
Maximum torque: 400 Nm @ 3600 RPM
Basically comes from computer upgrades and in the VT Sequential Fuel Injection
The Series II VS has more power thanks to the Cold Air Intake (170 something KW) and then the VT had a different computer, but the VN executive was the quickest car
what do u mean the quickest car out of the old commodores six? i thought vh was the lightest commodore tho.Originally Posted by greenfoam

i believe that the VN,Vp and Vr all had a 8.0:1 compression ratio and not a 8.4:1 ratio. as per the VS. Thats also when peak power and torque came on a little lower in the rpm range in the VS. its like a 100 or so rpm lower.
cheers
Yeah not to mention the roller lifters in the VT's
differance in the 5.0lt motor ranges
I would like to know what the differance are in these motors aswell becuase there where the standard ones @165kwand you had the 185kw and the 215kw and i think there was a 255kw could be wrong in the hsv series what was differant in these motors to make them all the differant ratings. I have a vr ss that I would like to give a few more kw's but would like to keep it sort of original in the sense of say around the 215 or the 255 kw range if it was around and keeping the mods to the factory changes would be fine for me.
Cheers 2dogs. sorry for any typo's
i think as the power went up in the 5 litre engines, they tweaked the ecu's and exhaust to get the power gains. i think the 5 ltr went up to 195kw in the vt's as a std stroke but the strokers went up to 220kw. the 255kw you mentioned was from the ls1. a good exhaust, maybe a cam change and a tune will see your power rising, cold air intakes, high flow filters as well.....there is a lot to do for the holden 5ltr....
I have all the easy stuf done already exhaust CAI good leads good sparkies and high flow filter I wanted to get a cam and chip pakage next but dont know what to get to get those extra power like I said before would probably just stick to what the General put in the higher spec motor's. Any body know what specs these other motors where?
cheers 2dogs

as EcotecManiac said.
power went up in the 5 litre engines (185i), due to a tweaked ecu/chip and exhaust to get the power gains, high flow air filter and CAI, also there might be a slight cam difference.. ?
i think the 195kw in the vt's use a std stroke, higher compression, again a different tune, plus roller rockers.
the HSV strokers went up to 220kw (also 205? and 215i). BUT.....
the CSV (corsa special vehicles) had the strokers up to 300Kwway back in 1995. but they where usually around the 230kw mark. the 300 was a special order engine.
Go a Good exhaust,CAI, a cam change and a tune will see your power rising. to abouve the 200 Fly/Kws, also try roller rockers.
if you wont more go a super charger on std bore/stroke. and if thats not enough go a S/C 355ci!
THERE’S NOTHING LIKE THE SOUND OF A V8 UTE CUTTING CIRCLES IN THE MORNING FROST!!
VN aeros were 5.0L 200kw - better cam, exhaust, roller rockers, tune, etc.
VN group A's were 5.0L 220kw - better cam, twin throttle bodies, head work, double row timing chain, roller rockers, exhaust, tune, etc.
The difference between the 179kw VT 5.0L and the 195i upgrade included cam upgrade, exhaust, tune, etc. I suspect that the VN - VS 5.0L 165kw to 185kw differences were similar.
VR and VS strokers, 5.7L, were from 215kw through to the fully optioned VS GTS-R which after blueprinting and balancing was about 237kw.
VT strokers, 5.7L, produced either 220kw or 230kw depending on the model.

VN Group A's were 215kw. The largest power output for the VT was the 220i strocker which was standard only in the GTS.

My badVN Group A's were 215kw. The largest power output for the VT was the 220i strocker which was standard only in the GTS.
AirStrike.... but I think there was a VT Senator Signature which was 230kw
It wouldnt have been any more powerful than the iron block stroker in the series 1 vt gts....220kw...i think it was the same or 215 kw
The VT Senator Signature came out with the 220kw stroker package but you had the option like with the "VS GTS-R" to tick the $10,000 HSV engine upgrade box which balanced, blueprinted and match ported your engine to released a few more neddies. Which put power output over the 230kw mark, but you'd expect something for your money when you've just spent a cool $105,000!
transfer of v8 into another vn
does anyone know the rough estimate of transferring a v8 from one vn into another i have both cars just looking at a price to get it done
Hey stumps5l what about some pics of the stato?

There was no HDT option for the blue printed motor on any of the 220i motors let alone in the Senator.

I Dont know what happened!
i was driving my car and then all of a sudden it just bogged down and then when ever i would put the accelerator down the revs would drop and i heard a knocking noise i know that doesnt sound good in any aspect, i am suspecting bottom end what do you all rekon. Help please.
did you oil light come on at anytime?
Nah the light did not come on. but it is all cool i got my mate to look at it, it is only the a fuel problem i totally got it wrong, hearing it was a fuel problem was probably the best thing i have heard. Big releif of my shoulders. **** i Luv 5L's, nothing better...
I can't find the web pages anymore but there were some that said the group A had much more power than Holden admited at the time, a fair bit more than 215kw, it also ran bigger injectors than the normal V8, also motor magazine ran a 14.74? in the group A, I have the original magazine and there was traction problems that day. Another magazine squeezed a 14.4 out of it on a drag strip, best 0-100 was 6.2 pretty fast for such a heavy carVN Group A's were 215kw. The largest power output for the VT was the 220i strocker which was standard only in the GTS.

ok well the vn group a ss had about 230kw at the fly cos my workmate has one and i drool everytime i see it because he bought it new and hasent done a single mod to it and ran it on the dyno last year at the show and shine....i was shocked
Boona15, that's cool, I've never even seen one in real life! but it's my all time favorite Commodore I guess most people say the same. I've seen heaps of walkingshaws but never a VN group A, ok well I did see a silver one not long ago but I'm not sure if it was real or not. It had stickers up and down the front gaurd and something about a forced induction shop and yeah it was just crazy fast when it took off from the petrol station even with a full car load of bare footed home boys from the city? : ). It wasn't from my town just passing through and I never saw that car again
hey anyone know if have vr or vs block, with roller cam, can i put a VT cam in and expect it to work fine?
