PSI_GTSII,

Thats pretty damn quick.. The vid doesn't really do it justice.

5-6secs from 100km/h to approx 175km/h.

My little old RB20det running 1bar used to run 0-175km/h in high 13 secs which was 7-8secs from 100-~175km/h.

Get your launches sorted!!! :rofl: 8secs is shocking!!

I can see how the DET head would be benifitial with acceleration.

They rev so much easier and quicker. Well my RB30DET does anyhow. :rofl:

But remember the first 2 secs of video I had'nt let clutch out :rofl:

Lol yer.. I was too busy watching the 100-175km/h. :rofl:

With a clean launch I used to be able to pull off a 5.2sec to 100km/h which is fairly close to yours with lots of wheel spin.

Obviously its the dodgy stop watch method but it was 99% repeatable so it was around the mark.

Are you running LSD?

I have a RB20DET in a VL with pod, 10psi boost and 3" turbo-back. It's not bad but I wish I had a bit of extra off-boost torque, once it hits boost it gets up and boogies though :headspin:

Thats the beauty of the RB30, in that video using all the gears (Ableit with slow shifts due to *whispers* holding camera in one hand) it takes 9 secs from 100 to 200kmh....I have another video of it, leaving it in 5th, going from 100 - 200kmh and it still does it in 10 flat!

Yeah that extra litre makes a *big* difference. I used to have a VN 5L with 200rwhp cam and chip with a shift kit, so im missing the torque and gear chirping. The RB20 should be more fun with 4.11's and a T28 though. Even now; when it eventually manages to hit full boost its alot of fun, but if you're in the wrong gear at the wrong time, its can be disappointing

A mate of mine ran a 15.8 in his stock auto 304 VL down the 1/4.

That's not as bad as you might think. What you have to remember is that trimatic V8's have 2.78 diff gears, compare that for example to an R32 skylines 4.3 diff gears.. apples and oranges.. chuck a 4.11 minispool and mild hydraulic cam, lifters and stiffer valve springs in and they're not so pathetic..

Considering most import Skylines have pod filters, raised boost and exhausts I don't think it's that unreasonable. While the V8's might be able to keep up or even power ahead on the straights there's nothing like a Nissan or Toyota to teach you a lesson through the twisties :headspin:

I used to own a VS 5ltr 5speed that ended up with a mild cam, ecu & 3.5" exhaust.

I found it to be quite gutless under 3000-3500rpm. On par with a R33 RB25DET I've driven. But it still more than the rb20det.

Even before the cam it was still fairly gutless and would bog down under 3000rpm.

The Auto's have a way of hiding this in the old GM EFI 5ltr.

The stock 3.08:1 diff ratio doesn't really help matters. First gear used to easily pull 70km/h. From a 5speed. Thats too high.

i have a vl turbo i like nothing better than blowing skylines away it has a 25 head on a 30 bottom end. tomei cams. cam gears . high mount manifold .50mm wastegate. t70 turbo running a r33 5 speed. 411 diff gears and a mini spool but after all of that i would love a skyline a lot newer stylish and a lot sleeker

Forget the VL Turbo:)

If your going to get a Commdore it should be an 8:) I would so love to buy a VL Brock Grp A, tremec 5 spd, alloy efi heads, Motec twin throttle body injection, Harrop brakes and stroker crank. 18: simmons , Tremec 5 spd...give the thing to a bloke like Ian Tate and get back a punchy 400-450hp engine, that will rev to 6,500rpm , sound tuff, run low 13s, maybe high 12s. With some shocks and susp tweaking it would be such a cool car...

...ive had my R32 for to long now, and would love a change, but dont really have the 35-40k required to build this sort of car:( You just cant beat imports for bang for buck:)

Not for everyone, but i think it would make for a nice change from my R32, but $17,500 as a starting point:( Id be lucky to get that sort of money for my R32 which would destroy and std 19 year old Brock:(

That car is nasty Roy!.....

Considering the R32 and Vl were designed around the same period, the Vl has a lot to answer for....

I agree with you though, a comodore should be an 8, not a turbo. I love the sound of a lumpy V8. Rock up at the lights next to an old phase 3 or something and the idle is enough to scare you. ha ha the RB20 sounds like an accord next to one of these.

Sheesh... that car hammers!!

@ around 80-100kms the dial jumps. Is that wheelspin or just a dodgy old tacho?

Although hard to notice it was wheelspinning in 2nd up to around 90kmh then speedo needle drops back to around 80 as it hooks up & accelerates back up to 100, then change into 3rd :(

The VL makeover was introduced in 1986, the R32 1989, the VL was only a facelift on a design that dates back to 1976, which in its day was quite advanced, VL certainly nothing to be ashamed off, Nissan to has certainly produced there fair share of 'Clangers' :D

Yeah, if you look at the VK Commo you can see where the VL came from.

And speaking of clangers --> R31 Series 1 Skyline (yucko). Series 2 they got their act together.

      No. I think it's gone. 😭 I think you can get body coloured ones on eBay so I think I'll get one of those... Or just hang a red ribbon from the hole and whack a TOW sticker next to it.

      Cleaning my wheels 😍

      By Milkmun · Posted

      Can't say I've had a bad experience with one on my car, then again it only gets washed once or twice a year... The wheels on the other hand, get a good spray often due to my shitty dusty pads.

      @MBS206 thats pretty neat and tidy to me!  I'll get a photo of mine when I'm out there next. It might require multiple photos to understand the scale of the atrocities though... In total I have 4 sheds of varying sizes and layouts. Main shed is 14x8, second shed is 3x8, third shed is 11x2.5, fourth shed is around 6x4.  All are pretty much full.   The main goal of my cleaning tsunami is to make the main shed predominantly car and motorbikes only. Second shed is my metal fab room (2 x bench grinders, drill press, bench belt sander, metal band saw, scrap metal storage and some of my garden tools.  3rd shed is more bigger garden stuff, storage for engine crane, jack stands, concrete grinder, concrete mixer, air compressor lives there, and it now has two 2mx2m pallet racking shelves with itemised boxes holding building stuff, electrical stuff, plumbing stuff, etc, etc.  The 4th shed is Ryobi electric ride on mower, mini boom sprayer, ancient Kubota tractor, more garden stuff!  I have got a lot of shit....  Then there's the pool house (8mx4m) and the pool pump shed (4mx4m).  I built all of the sheds over the 11 years we've been here.  The main shed was a Ranbuild kit, the rest are all custom made to fit the areas available. Building the main shed taught me a LOT as I had no idea about building anything prior to that!  I've still got one more in me. It will be my man cave which I poured the extra concrete for way back when I poured the concrete for the main shed. The idea is the Skyline will be a centre piece of the main cave once (if...) it's finished.  I told my now 14 year old son yesterday that I will 100% drive him to his year 10 formal in 2 years. Still a long way off but at least I now have a date to work towards! 🤣

      Modern oils are amazing. Add tyres to that as well.

      Probably a smart choice to buy one vs build, purely for the motivation part as you said! Imagine the metal dust everywhere from grinding all the steel to build one. Ha ha ha!   Also, post a photo of your garage.   Mine is below, this is where I've been cleaning and have already half filled a caged 6*4 trailer. And this is after my cleaning expedition mentioned previously... The middle normally has a car in it, but I'm dumping things in the middle as I sort through them. And poor skyline was dusty and has had the lightest few drops of rain and now it looks atrocious and needs to be dragged back out and washed thoroughly! And yes to the right is technically another bay, you really can only see 2 bays out of 3 in this picture.
