G60 or VR6 for modding?

Recommended Posts

when I bought my g60 last week, I had no idea that the vr6 was the replacement for the G60 as the flagship model.

 

I bought the G60 cos it was cheaper, but am just wondering, if more power is sought, surely it is much easier to get extra power from a forced induction car than a 2.9 litre normally aspirated?

 

I admit that you can always super charge/turbo charge the vr6 but that is a lot of work. money in changing engine internals etc.

 

If you arent going to go too wild, doesnt this make the G60 a far better and cheaper proposition for modding?

 

 

also, without changing internals, what are the realistic limits of tuning of the g60?

 

I shouldnt really think about this, but without the impreza finished, the tuning bug will simply attack my other car!

 

thoughts would be most appreciated.

to put a supercharger on your car you dont have to change the internals

Z-Engineering Supercharger Conversion

 

The Z-Engineering supercharger conversion is another popular add-on for the VR6 motor. Making a name for itself an easy bolt on accessory, this breaks the mold.

 

The Z-Engineering supercharger is revolutionary in that it doesn't need an oil feed to cool it's ceramic bearings. Along with the fact that its modest boost levels mean the VR6 needn't be modified internally, this is a modification that gives reliable horsepower, but can be reversed should the need for a standard motor present itself.

 

With power in the region of 250bhp from a 2.8 motor, this addition takes the VR6 a serious performer

The g60 is a very tuneable car. You can get 250bhp reliably from it without too much hassle the main point to modify is the cooling for it as this is a weak point on the g60 moter once you've got that sorted you can do things like porting and pollishing of the head and inlet then there's the charger if you get that flowed and ported with a chip and pulley you will already be seeing the beat part of 200bhp then theres things like the cam and induction. Your best bet if you want advice on tuning your g60 lump is to speak to darren or john our very own g60 specialists on this site darrens number is 07786235233 and they'll be able to set you up with a package that will top the 200bhp mark without a problem.

couple of quotes taken from VW vortex:

 

I could write volumes and not really answer this question - then the next guy to come along would probably disagree on half of what I said. It really depends on several things: 1) what you want to get out of the car, and 2) how much time/money/energy/blood/sweat/tears you have to put into the car.

 

The first thing to ask yourself though is: "How much do I have to spend?" If you only have $4 or $6 k or so, I'd say stick with a g60, and keep it stock until you have some extra cash. But if you have something like $8 or $10 k to spend, and you want an SLC, go for it. You can find SLC's for less than $7 or $8 k, but they will probably have a lot of problems. Plus, it is really a good idea, imho, to spend less money than you have on the purchase of the car - that way, you have a bit laying around to cover anything that comes up immediately.

 

The g60 Corrado has several things going for it. It is lighter, has almost as much power stock, is cheaper to buy and maintain, and is much cheaper to tune. The SLC is a nice car out-of-the-box, but it is more expensive, heavier, and much more costly to tune. Of course, if you are filthy rich, the VR6 engine will have a higher potential output. But, imho, even that point doesn't mean much. A fully tuned g60 will have you near 200 hp and 200 ft/lbs of torque, which is, again imho, about as much as you want in a front-drive street car.

 

Here's an example - $500 spent on tuning a VR6 will get you a set of cams and a chip. $500 spent on a g60 will get you a stage IV kit. The end result in power will probably be pretty similar, even though you had to spend a couple grand more to get the SLC in the first place.

 

When buying any used car though, the most important thing to consider is the care the previous owners gave the car. If they beat it up, stay away. If they tell you they did x, y, and z to the car, make them show you reciepts for the work. Don't get taken. There are a lot of Corrados out there that have been beaten to death, especially g60s.

 

There are several common problems to look for with each car. The most important thing to look for on a g60 is the health of the charger. If they can't show you a reciept for a recent rebuild, then figure on spending about $700 right off the bat to get the charger rebuilt. It is very very very easy to permenantly damage these chargers to the point where they aren't rebuildable, so the best insurance is to rebuild before they show signs of needing it.

 

Here's my opinion of each version.... I own one of each, so I think I am in a position to give an unbiased reply.

G60 - The elite of the VW pocket rockets - Takes over where the Scirocco left off. Lighter than a VR6, the G60 also combines a front suspension design (less caster than VR6) that promotes faster response in the turns. Other suspension differences include stiffer springs than the Vr6, and a slighlt lower stance at stock ride height. The G60 engine is a better design than the VR6, with the engine itself being more relliable. The supercharger is the weak point in the G60 design, prone to failure if abused/neglected, with varying reports of maximum mileage from a factory unit (70K-150K miles, with 70K closer to the norm). When driving a g60, the engine noise is very noticeable. G60 cars are also cheaper to modify, with performance parts bordering on reasonable $$ amounts.

----------------------------------------------------------------------------------------------

Vr6- Not just a refined G60. Major engineering changes affect the handling characteristics of the VR6 cars. The "plus suspension" design makes the car more stable in the straights, but requires slightly more steering input for cornering. You can REALLY feel the difference if you drive both platforms back to back. The VR6 springs are noticably softer that the G60 units, and the car feels a bit smoother/less responsive as a result. Small refinements to the exterior combine to give the VR6 a stockier meaner appearance, with later VR6 cars having an updated interior with minor changes to the dash controls, door panels, etc. Vr6 engines had their issues when debuted, and many of the problems uncovered were not addressed till 95, so the corrado did not get to benifit form them. Some common issues include headgasket, timing chain tensioners, cooling system (VR6 cars run HOT!!!... 230 degrees is normal). Performance upgrades for the Vr6 are in the rediculous $$$ range.

thanks for the responses guys, very helpful.

 

Its all academic as I have bought the G60, but I didnt buy it to mod it.

 

Personally would not want to deal with some of the companies mentioned as I had horrors with them in my old golf days when one of them supplied me with a dash board. I got the impression I was being conned, was sorted eventually, but a word of warning, dont get an amateur to put a mk 3 golf dash in a mk2 car!

 

Anyhoo, darren etc already has my car and will do until hopefully this weekend.

 

I suspected the charger might be on the blnk so I had the AA take it to him/them.

 

Turned out my charger was lasting well, the fact that my cambelt tensioner had seized made me feel all the more better about sending it to them to get everything done in one go.

 

I take it darren has a good rep on here then? he certainly seems to know his stuff, has been very helpful on pricing and has lept me informed all the time.

 

So far have been very happy.

 

Must admit, at first I thought it was the general consensus to go to jabbasport etc. who seem to have cornered a market.

 

Is there anything special about the likes of jabbasport and tsr? so far I prefer the personal style of service I am getting, plus darren seems to genuinely care about what happens to the car!

Dazzyvr6,quite fancy the idea of a supercharged vr6 it would probably give the car more low down grunt than it has now.Don`t know about buying from NSR though have you heard any reports ,2.5k seems quite cheap for an extra 60hp.

I remember seeing the supercharged Vr6 in Performance VW a couple of months back,that was cool and fast a real street sleeper. 8) 8)

not my thing really.

 

I dont believe in forced induction without dropping the compression ratio.

 

Decent NA cars are 10:1. running 10:1 with low boost is really a little lame if you ask me.

 

AFAIC if you are going to do it, you have to do it properly, this means low compression forged pistons, and billet rods, with some decent head work.

 

 

Aside from that, it never occured to me that the 2.9 was such a heavy engine.

 

I presume these are all steel blocked?

 

the engine in the impreza is entirely ally (apart from bores and rods of course), and if you are fairly strong and ahve a good grip, can be lifted by one man!

Hi mate,

 

If it is just modding only you really want to consider then the G60 is the better prospect full stop - you can get 200bhp relatively easy with a few well chosen mods and is relatively cheap to do....

 

The VR6 on the other hand is expensive to tune but does produce 190bhp from the outset.... a chip, cams, induction and exhaust with remap can see 215bhp... but will set you back about £1500 - 2000...

 

I had this delimma myself and thought it would be unlikely for me to modify my Corrado as I have to use it as a daily driver... I also needed something refined and smooth that can hack motorway miles.... so I bought a VR6... dont regret it one bit - 60mph in just over 6 secs in standard form isnt to be sniffed at.... :D

 

But in a few months I might just 'have' to buy a G60 to play with 8)

 

Cheers,

 

Scott

The G60 is a great motor to tune. As standard you've got 160BHP which can leap to 200BHP with just a chip and pulley. :p

 

THE most important thing is to get your charger rebuilt and preferably ported. After this, make sure you check your vacuum hoses since they are prone to perish and will result in poor running of the car.

 

Its always best to tune the G60 in stages, go for just a chip and 68mm pulley to start with. Then as the tuning bug bites harder, think about a cam and flowing the charger etc. An external oil cooler is an important add on since the standard water system is inefficient and obviously more heat = less power and your charger seals will shorten in life.

 

THE most crucial aspect of G60's when it comes to tuning is fuel delivery. With higher than standard boost, you must make sure that the map you use provides instant fuelling and enough to keep you on the rich side of 14.7:1. Preferably between 12.5 and 13.5:1 under WOT. Otherwise say goodbye to your pistons :(
