[156] My list of recommended upgrades

Hey guys,

After some years of ownership of alfas and endless research i haven't stumped upon a list of recommended upgrades for the 156.


The list is probably 10 years late, better late than never right ?

Anyways here it goes:
(an [X] means its fitted on my 2.5 98 156)


Audio
[X] Headunit: Parrot Asteroid Classic - remember to download the official Alfa Romeo firmware
[X] Subwoofer: Pioneer TS-WX710A - Really sleek OEM look if fitted in the boot

Brakes
[X] Discs: MTEC Grooved and drilled
[X] Pads: Ferodo DS2500
[X] Lines: HEL Braided Lines - alternative is Goodridge Phantoms

Engine
Airbox: BMC CDA - Remember to purchase a new Bosch MAF when upgrading to this.
Intake: Polished stainless steel intake manifold - hand made in Italy, looking really sweet with original chrome inlet runners.
[X] Battery relocated to boot - this is essential if fitting BMC CDA
[X] Gear: CLOS Quickshift (not recommended) - Go with the MTECH one or Highpower-Racing QS KIT (top stuff)
[X] Engine Mount: Original fitted with Powerflex works like a treat.
Radiator: Hand welded high flow aluminium radiator with twin water core - tested in 2.0 TS fitted nicely.
Exhaust: Wizards backbox is topstuff - heard it on a GT, its 1st on my wishlist .
Differential: Quaife Helical LSD - Autolusso seems to be the cheapest supplier.
[X] Clutch: Sachs Clutch Kit - Custom Made + Reinforced 15%
[X] Tray: Alfisti Aluminium undertray - The Jap flatout guys also makes an aluminium undertray kit its pricy though!

Exterior
[X] Crystal projector head Lamp with dual CCFL rings in black housing
[X] Crystal clear repeaters
[X] Smoked tail lights
[X] GTA Multispoke 17" Dark metallic
Sideskirt: Bertucci MAR110
Spoiler: Zender bootlip - alternative Lester bootlip spoiler

Suspension
[X] Damper: Koni Sport Kit (yellow) alternative is Koni FSD and since the price these days have fallen on FSD this might be the better option.
[X] Springs: Eibach Pro 30 mm.
[X] ARB: Alfastumper ARB kit front 26mm & rear 19mm - Since alfastumper is unresponsive i would recommend the Eibach Anti Roll Kit.
[X] Droplinks: Aluminati front+rear adjustable drop links - The ends are changeable and cost 12£.
[X] Wishbone (upper): FRAP with reinforced bushes are an better setup than original wishbone fitted with powerflex.


Please come with additions

Aren't the Quaife an better option since Q2 have become so expensive ?

Also looking for a clutch replacement, thought of Black Diamond but those are apparently prone to die fast.

CG Motorsports Dual Friction Clutch Kit looks sweet but those are only made for the TS engines ?

that's why I mentioned Q2/Quaife.... Either one will do, whatever is available/cheaper. Not that much difference function wise...

Black Diamond Kevlar friction disc and groved clamping plate held NO MORE TORQUE than a standard clutch on mine, it was a complete waste of time, labour and money. Stay well clear of Black Diamond.

Sachs uprated clutches actually hold more torque.

simple four parameters determining clutch power
- effective diameter
- number of plates
- clamping force
- friction coeficient

first two can't be changed easily
clamping force (is what imho makes Sachs clutch different) but affects also clutch pedal feel and change (weaken) through the clutch life
friction material is what to experiment with (beware, each material behave differently - different torque transfer bias, optimum/max operation temperature(=> needed surface area))

Been talking with CG Motorsports they do make a kit for the v6's

So this:

CG Motorsport Dual Friction Clutch Kit | CG Motorsport (+40% torque)

or sachs:

http://www.sachsperformance.com/Sach...rced::312.html (+15% torque)

Bit of marketing trickery there, you have to read the small print.

Sachs rate their clutch for 15% more than the standard clutch can hold (Vectra ones hold over 500NM standard so as much as 590NM potentially)

CG rate their clutch for 40% over the standard vehicle torque (400NM * 1.4 = 560NM)

So they actually will likely hold exactly the same. Very unusual for Sachs to not state a specific torque rating for one of their products. It looks like what I got and stuck on the Vectra F40 transmission, an organic and metalic mix with a non self adjusting cover plate of much higher clamping pressure. What I did find though is that the Sachs cover plate did not clam all of the friction material on that side. The result is less aggressive engagement of the clutch but when in high gears accelerating it happily holds much more torque. The down side is that when rapidly changing gears and trying to slip the clutch to get off the line, the clutch over heats and torque capacity drops, making it more difficult to get a good start.

If you go for the paddle style clutch from Sachs, they rate that for 600NM and they always state the minimum it will hold.

If you ring/email Sachs and CG and ask for specific torque ratings, you'll get a more usefull set of figures for comparison.

Where did you find the small print on CG's site?

So Sachs is the recommendation then ?

The CG one says 40% over the standard engine torque, not more than a standard clutch.

From CG - Please note Dual Friction Clutch Kits can create judder when setting off. This is normal and acceptable because of this upgrade.
If you are willing to live with the (possibility) that it will happen to you, then sure go for it... But you are not going the turbo route, so absolute clamping force upgrade is not the issue here...

Personally I think I will feel better buying SACHs for my daily - for my turbo racer project I'd go for the CG

Double check they sent the right friction disc as they sent me the wrong one (despite me telling them which gearbox I have).

It will smell a bit to start with, that is normal.

You will have a stronger leg in a week.

I'm still on a standard Sachs DMF, with the 500+NM Sachs uprated organic friction disc and heavy clamping cover plate.

Delta III 1.9 TT

Dont go for FSDs on Eibach Springs, they will wear rapidly (minde did not even last 60.000km) way to expensive for such a short lifetime - while not leaking any oil the car was not feeling well planted on the road - a test on the local Bosch testbench reveled they were worn, all 4 of them, there was next to no life was left in them. In fact i would not touch anything made from Koni anymore.
Now using KYB-Excel G - nothing fancy but, they do have nearly 100.000km on Eibach Springs and are still working as intended. For a friction of the price...

For the Short Shifter:
might take a look at MTech,
http://www.short-shifters.com

If the V6 uses the M32 gearbox they most-likely have something that'll fit, the F40 thing works fine on my delta

EDIT:
as for the Radiator - are you shure a rad from a 2.0l R4 will be sufficient to cool the V6?
mine had a verry high tendency to get verry verry, verry warm....

I belive the 1.8/2.0/2.5 is the same radiator the 3.2 is also same size just having different mounting points?

Really disappointed hearing that the FSD failed so rapidly

The 1.8 radiator is the same as the 1.6. The 2.0 with AC is the same as the 2.5. The 3.2 used a copper rad with the same mounting points, etc as Alu based 2.0 / 2.5. Copper transfers heat a bit better than Alu, but suffer corrosion much worse. So your call to fork out the extra money

My 3.0 SW conversion work ok with my (rather old) 2.5 rad.

Imo the Valeo radiators are thin as paper and not worth the price, nothing more solid than thee aftermarket handwelded alloy radiators.

Also the greater core size makes up for the poorer heating transfer (alu/copper wise).

Really dont like the quality of the CLOS QS kit also alot easier fitting the MTEC one since its in the engine bay.

That could work well Also the OEM / Valeo radiators have plastic end-tanks that are responsible for 50% or more of the failures...

EDIT: Bleed screw is nice too... Picture is just upside down...
