84 GTV6 in Hong Kong - Upgrade advice needed
I am looking to upgrade my GTV6 and like to seek your advice. I am looking for simple solution as the mechanics in Hong Kong has limited knowledge, nor patience, in fixing vintage cars. I am afraid that any non-straight forward work will do more harm than benefit. Just wanted let you be aware of my constraints.
1. Gearbox - I mostly travel in hilly , winding roads and don't usually go beyond 120kph. I am looking for closer ratio from 1 to 4 so I can maintain the rev beyond 4000 at most time.
2. A/C - I need a more powerful unit. I heard that Milano unit will fit nicely with modification needed
3. Suspension - will koni sports and new spring do the job ? Pls advice on spring. ( Tires 205/55/15 )
4. Breaks - stock unit fades after 10 minutes of hard driving because there are turns every 50-100 m. Will an disc and pad upgrade, together with SS hose do the job ? Try to avoid changing the calipers for the above reasons
5. Steering - need advice on how to add 1-2 inches extension on the column.
Thanks guys

Wowow,
What a great looking GTV6. Have fun with your new acquisition.

1. I can't help you here.
2. Yes the Milano A/C compressor is a very good upgrade.
3. Everything I have to say about suspension is here: Performance Page
4. Good pads, fluid and stainless lines will help a lot. If you want to spend more money vented rear rotors and many front upgrades are available.
5. The 85' and later GTV6s have a longer steering column, the 83's and earlier don't. I have no idea which one the 1984 car has.
Greg,

1. I don't know the GTV6's very well, but don't most of them have the 3.55:1 diff ratio? If so, the 4.1:1 Milano/75 diff would be better for you.
5. If your car has an aftermarket steering wheel a spacer should work, or you could get a deep dish steering wheel:

not trying to sound like a smartarse  , but I have done most of this to my car, so here is the benefit of my experience  :
1 - you can get a twinspark gearbox which will give you closer 1,2,3 ratios and a 4.1 LSD, all of which is great for backroad blasting. Its not a straightforward swap though due to differences in linkages and speedo sensor. You will need to find a workshop that can deal with that first, otherwise, just put up with a low first and big gaps to 2 and 3.
2 - you need a new efficient rotary pump (from a milano is fine, but a generic unit will work fine and be cheaper) rather than the old crappy piston pump and then upgrade all the lines etc. Probably worthwhile in your climate - I've done it and found it still only marginal hence have ditched it to save weight on the racetrack. A good AC specialist should be able to deal with this.
3 - Koni sports and stiffer rear springs (but don't go crazy - Kings Springs do a nice variable rate coil) will make a nice supple responsive road car. That's what I had before I went nuts and doubled the spring rate to get it to handle on the track, which is another story altogether. A correct wheelalign (with correct toe out) and thorough bush replacement will also help. Any suspension joint could do it, provided they have the right bits and specs.
4 - Better pads, and new everything (eg caliper seals and rubber hoses, stainless is mostly wank IMHO) is all you'd need for most road driving. Ferodo racing ds2500 pads are good as the only need a little warm-up to work good but give the bite needed when hot. Going bigger front discs and vented rear will also do the job, but is prob overkill (unless you are a complete maniac). Possible to do self if you know a bit, but brakes are important so take to a brake place if in any doubt.
5 - Buy a wheel with lots of dish. Sparco and Personal do nice ones (google is your friend) and/or fit a Sparco 60mm hub extender along with a Sparco/Momo/Personal wheel (others may fit also, but they're the ones I know about). Getting the old wheel off will be the main drama and probably needs a puller of some sort.
If you do all of this, you'll have my car (well, as it was 12 months ago before I took it onto the racetrack) and it was (is) a good thing.

gtv6 had 4.1 like the 2.0/2.5 75 shame there isn't 4.3 or 4.5 easily (and by that I mean cheaply) available
A drift wheel in an alfa - and you call yourself an alfista?

Hahaha.... Yeah it's the same one I have in my car. It seems to fit with the 80's theme. With the 20mm spacer, gives around 70mm offset compared to stock. The horn button that came with it read something like "Advanced Sports Horn Switch"  I think the 90 had the 4.1:1
wowow, with parts, it's pretty much all available here if you have trouble getting it in HK. Or with the weak American dollar you could probably get it from Performatek (Performatek - Home) EBC green stuff pads are also good for road driving (don't need heating) I looked at a Nardi 'deepcorn' deep dish steering wheel but refused to pay the AUD350 pricetag. Sparco might be cheaper, but still expensive.

Having digested all of the advices ( once again thanks ) :
1. None of the mechanic in HK is familiar with GTV6 and therefore will not risk putting in a Milano set. I'll just rebuild the existing tranny.
2. Will fit a Japanese rotary unit
3. replace all bushings and ball joints, get Koni Sports and new spring
4. get new non-drilled rotor, new pads ( Axxis for a more progressive feel rather than brutal stopping by track pads ) Not sure if SS hose will add to performance.
5. Will look for ways to extend the column because I want to keep using the stock wheel.
More advice welcomed.
5.

 At least that is the case here (US).
