Hey guys, i was just wondering if you could help me out here and fill me in on a few things. What is the difference between a VL calais Turbo and a VL Calais V8? I know the turbos had a bigger kW than the V8s but the V8s had more torque. Now which car is more reliable? Which is easier to fix? Which is the easier to maintain? Which is more fuel economical? I'm after all the stuff like that, kinda to weigh one up against the other.... Cheers 050VL

u should'nt decide with facts on paper - it's totally different world between v8's and turbo 6's. you should just go with what you prefer.

Thats what i'm after, getting some facts down in front of me from ppl with experience with V8's or turbos, or even better both. But only of the VL Calais variety.... 050VL

V8s tended to crack manifolds V8s used more fuel V8s were old technology ( carby) VLT was and is far better car than V8 VL

I got done by a VL Turbo last night...my V8 (5.0L) is on gas though, and isn't tuned properly (it claps at low revs) so we'll wait and see. I thought it was a V8 till i heard it go around a corner and hear the blow off valve Some original photos have not been recovered yet.

Mate if you are worried about all that then I think you need to go for an atmo, or hyundia Excel.

What is the difference between a VL calais Turbo and a VL Calais V8? Turbo is available as manual as well unless you wanted a HDT V8. Now which car is more reliable? V8 (less things to go wrong) Which is easier to fix? V8 (no elec problems like the 6) Which is the easier to maintain? V8 (carby engines any one can work on) Which is more fuel economical? Turbo (can also have worse depending upon your foot) Note that i own three turbo cars. It all comes down to personal preference on what you want. Corsa

Maybe some dude tried to put a machined manidolf on non machined heads and cracked it that way, or absolutley boiled the motor to death. As for using more fuel, that's an understament! My V8 Calais when carby'd was good for just 260k's around town and an atmo manual 6 would beat it. Now it's injected, uses HEAPS less fuel, starts when you want it to and has some more go also. Having owned both, factory vs factory, i'd say the turbo is a much better car, but there are more things to go wrong and more expensive things to fix too. It's also now hard to get an unmolested turbo example in good condition, but they are still out there.

v8s sound better and usually hold there price fairly well!

The Turbo engine is worlds ahead of the stock V8. They love a few simple mods, and for the cost of a grand or two you'll really be putting out some power, while that ammount spent on a v8 would hardly get you anywhere. The turbos hold their price better as well (not the other way round as said above) It is more complicated to work on though. Some original photos have not been recovered yet.

You would be surprised how many people who get into my car start wistling along with the turbo. And as for holding value you could probably sell a stock calais turbo for $15,000 you would be lucky to get $10,000 for a 5.0ltr

I have heard it costs more money to get the equivalent horsepower from a V8 as to a turbo motor. A VL these days if getting one with the original parts may not be as reliable as say an injected 8 as a lot of the RB30's are now 15-17 year old with high kms which tends to make them more troublesome with the older parts (i.e. broken perished and corroded terminals,leaky injectors,corroded parts and perished hoses,etc in the cooling system),I have had a couple of VL's in the last 6 - 7 years and never have went through common parts like the CAS unit,only parts like a remanufactured AFM and second hand injectors but that was in an N/A. This by the way is comparing this motor to the likes of a low km VS - VT 5 litre,on a turbo engine you would also have to take the turbos condition into account. RB engines are a damn strong engine as one SDU member has 240,000 kms on his RB20DET powered R32 Skyline and is still going strong,the best engine overall I believe is the DOHC RB motor which is better in design than both a 5 litre (unless you are talking about a VT 5 litre with roller rockers,etc fitted standard) and single cam RB motor in areas such as the valve train which has greatly reduced valve train components which makes for less friction from moving parts. The engines with standard rocker arms seem to be hard on the valve guides whereas the VT 5 litre has roller rockers which reduce friction in the valve train are easier on valve guides,the twin cam RB motor has finger cam lifters or followers mounted between the camshaft and valve stem which is ideal. But as I mentioned reliability wise providing the RB30's cooling system is bled properly,the oil is changed regularly and it's a low km or rebuilt motor they are a good motor as I saw nearly 500,000 kms out of an N/A motor,it was still going but was just the typical old motor,just a little smoky and everything on it like coolant hoses,coolant hose fittings,injectors,etc had had it.
