Hi peeps, just joined. Being on the verge of selling my skyine gtr r33 v spec for something different but still with power. Not in love with the porkies but love the stance/looks of the monaro especially the vrx. Is there much to go wrong with them and are they easily tuned, re-mapped etc. Are they very twitchy in the wet, being rear wheel drive. Would appreciate any advice/info if there is anything to watch out for when buying the vxr I have about £22k for one but can stretch a bit more if I send the missus out on night shifts.

Very solid drivetrain and loads of performance parts to get as much power as you want from them. Well depending on your wallet. 6L is a good start point anyway.
Check the boot out to make sure you dont need the space. Else you might be better off with an earlier 5.7L model.
Different engine layout between the 2 but they are basically from the same family.
Yes twitchy in the wet especially with traction control off, though many see that as a good thing!
But again aftermarket controllers are available to handle traction if thats what you like.

What colour do you want?

Try and find one with a Wortec exhaust, remap and ripshifter.

Does the vrx 6litre have the 400bhp (at the flywheel?) or is that manufacturers figures. Would the exhaust and re-map put much bhp on?
I'm looking for one in black, but have read on one of the threads that they may be doing one in purple. Would defo. be interested in that colour.. I've seen some 07 registered vrx 6 litres for sale at £26.750 then others at £35k plus. Just wondering what the difference would be as they seem standard from factory.

Not a VXR i know, but have you looked at this one? www.pistonheads.co.uk/sales/143011.htm

To recreate this, even in a vxr is going to cost well over £15K.

Purple will be for the 4 door VE sedan VXR8. Its not a coupe like the VXR. Confusing for sure. Maybe Vauxhall should have kept the HSV nomenclature.

Anyway, go with the cheaper VXR's as they are the same, maybe its just mileage thats different etc. You wont be getting a new coupe for the next few years as they are no longer made. The new VXR8 is due mid year and is based on a totally new platform. Bigger stronger and faster than before. Much like Steve Austin

Thats probably the best bang for buck Monaro available for sale at the moment for sure.

The 600bhp looks a good motor, good for the strip, but I'm looking for an everyday fast road vxr, would you say 450bhp is ample and a very usable power. IMO being rear wheel drive the 450 should be ample

Yes, but who needs ample Mine is around 500bhp and it could still handle more

VXR Do you run yours at the pod? At 500hp what times would you be doing and terminal speed? Would you have to uprate the clutch and fuelling at 500 plus bhp or can the standard units handle the extra power.

Not yet

As for clutch/fuelling my understanding is that they are ok at 500bhp but add in another 100bhp and changes would be required.

Yeah they say around 450rwhp then fuel system upgrade. The injectors will need replacing before that though.
Clutch is the weak link. Trans is pretty strong. Diff might go soon after. Id say 450rwhp was about the level before you need to start swapping stuff out. Traction issues will reduce any major breakages in the driveline.
450rwhp is around 550 engine. I think thats a nice level for daily use. With some agressive driving its plenty fast. Many however will disagree

Regards the traction issue on the standard 6ltr. vxr. What is involved in the uprating of the traction control system and how effective will it be over and above standard, also cost outlay to get it sorted. Bit too old now for the drifting scene and prefer to be safe than sorry. Friend has a gtr r34 v spec with 580bhp. He has uprated his clutch but I find it hard work around towns. Need legs like swartznieger to press the clutch.

Roger has just fitted an LS7 clutch for me, which by all accounts has a stock feel but is factory rated for 505bhp, so should be good for 600 odd. Guys in the US like it over some of the aftermarket clutches.
Ill let you know how it feels when I get it back. I dont think Roger had too many issues with fitting other than some of my pipes and connectors on the old clutch being seized. Plus its cheaper than most.
The textralia has a fairly light action too. I think a couple of guys here have one. Stevieturbo from memory for one. They have some pretty strong setups that will take you to 1000bhp if thats your desire.

I find the std clutch in the 6.0 VXR pretty hard work, then again I never could run very fast. I'm a little confused with the clutch issue. If the std clutch is ok upto 450 rwhp why does the retrospective upgrade of a std VXR to a VXR 500 require a better clutch? I take it the 500 of a VXR500 isnt rwhp so surely std clutch should do fine?

With close on 400rwhp I believe without an upgrade in TC to racelogic anything much over 500fwhp will present traction problems in the dry and that is how you may loose out....great fun and vey expensive for rubber but lesser cars will get the jump on you..at least with 500+hp you stand a chance of realling them in

The VXR500 doesn't require a better clutch, it has "clutch modifications", not sure exactly what that means but I am sure Wortec/Greens could enlighten us

On to the traction control of the standard 6ltr vrx. I will be looking at a few vrx's next week and obviously I will be asking questions. Is it very involved to uprate them and roughly what cost would I be looking at. Is there many manufacturers variations on this. I would only be looking to mod the car to a safe 450bhp. Does the 6 litre standard model produce the 400bhp and 0-60 in 5 secs. Estimated 0-60 if I remap and change exhaust to get it to 450bhp?

thanks.

Why up the power, only to then stop it with traction control?
The whole point of the RWD V8, as those of us at the drift day know, is to be able to hang it out sideways!

Isnt that what the right pedal is for? Controlling traction?

Seems insane to me, or maybe its just me thats insane!

Miss my point. I'm not using the car for drifting, if I wanted that I'd possibly get a skyline gtt single turbo and non v spec. I'm used to the gtr vspec with atessa system which is very safe even when you step it right out, it will correct itself in a minute fraction of a second. The last time i had a rear wheel drive was a carlto 3ltr gsi which was a pig to control in bends. just want info. on the traction control factory set up and up rating. Hoping you guys would have some info.
