Thought I'd post a few videos on what I've done to my 2001 986 Boxster S after a year of ownership and what mods I've got lined up for the future.

Video is here:

Porsche Boxster S 3.2 Tiptronic (986)

I wanted an everyday car I could track occasionally.

She’s called Belle

Stats.

252 Bhp, 305 Nm torque,
0-60 takes 6.5 seconds, ,
In the owners handbook its states the Boxster S Tiptronic version should weigh between thirteen hundred and thirty five kilos (1335 kg) and fourteen hundred and fifteen kilos 1415 kg , so we’ll take an average of thirteen hundred and seventy five 1375 kg for now
Gives a power to weight ratio of 183 bhp/ton

Had car for 1 year and driven 6,000 miles

Real world mpg
17 mpg intown.
30 mph on motorway
Using Shell vPower petrol (99 RON)

Maintenance done

Engine Oil+Filter Twice
Brake Fluid Twice
Transmisson Fluid
Coffin Arms (bush in one place could see daylight though)
Air And Cabin Filters
Engine Serpentine Belt
Brake Pads – EBC Bluestuff
Fuel Filter
Aircon Topped Up
Spark Plugs

My mods

Bulbs – Phillips X-treme Vision
Custom Cup holder build
Tyres – was pirelli p-zero russo now Michelin ps2
CD player removed and iPhone auxillary fitted with holder
Spare tyre removed. I carry tyre weld for punctures.
GT3 brake ducts installed.
Four wheel laser alignment

Things to do

Refurbish complete braking system – the hoses, master cylinder, servo/booster and caliper rebuilds
Rear plastic window has a crack
Alloy wheels have some paint bubbles
Squeak from rear of car- could be engine mount, transmission mounts or suspension top mounts?
Coffin arm bushes upgrade to polyurethane (Powerflex)
Check and replace fluids – coolant, power steering and differential if needed

IMS Bearing repair
1997 to 2004 and it affects all Boxster, Caymans and 911’s from that time period. The purpose of the intermediate shaft is to drive the camshafts indirectly off the crankshaft. If the bearing in shaft fails this can affect the valve timing causing massive engine damage. The fix itself is relatively straight forward you replace the bearing with a 3rd party version that doesn’t fail.

Performance
One thing I wanted to investigate is increasing the power of the engine. What intrigues me is that 2001 Boxster produces 252 bhp but the 2005 model has the same 3.2 litre M96 engine but produces 280 bhp which is 28 more. It would be interesting to find out what changes were made and seeing if I could get the same result.
