A few months ago I found myself in the position of wanting to change my car for a 996 or modify my 993.

A month or so of mental torture and sleepless nights ensued, I finally made the decision to keep my car and inject some dianabol into the proceedings. I made my decision to keep the banana since I would not find a 996 as unique as my 993, and although the 996 is dynamically a better car I think it’s more refined nature might not give me the same thrills on weekend blasts as the older car (I only use the banana for fun).

The next step (and 2 months more mental anguish) was to decide who to use for the upgrade work. This is where things got really tough for me. In the end I have gone with an RS Tuning kit, which should produce 520hp / 700 NM.

The engine is having a rebuild and the upgraded components fitted at Tech 9 in Liverpool, then the engine only is been shipped in a crate to RS Tuning in Germany for mapping on their engine dyno.

For the sad people (like me), the actual rebuild and upgrade work consists of:

Rebuild work:

New big end/main/thrust bearings set
New piston rings
New tappets
Top end refresh and recon cylinder heads
New HT leads
New distributor cap
New diverter valves
New intercooler hoses
Replace rear diff plates (with GT3 sintered items)
General check and fettle of suspension bushes, drop links, etc

Upgrade bits:

Carillo rods
RS Tuning flame rings
Gas flow and port cylinder heads
Sport camshafts and vernier conversion
5 bar fuel pressure regulator
Upgraded oil cooler
K24 RS ZC turbos (more on these below)
Cargraphic 2.5 inch race muffler set
Cargraphic 2.5 inch 100 cell cats
Uprated clutch and LW flywheel
BMC airfilter
ECU remap

Other stuff:

Sports steering wheel
GT2 front anti roll bar conversion
R600 brake fluid
PFC 97 brake pads
New trousers and portable commode under driver’s seat


The turbos themselves are very interesting, they are K24 RS units that have been rebuilt by a top turbo chap (Kevin - for those who use Rennlist) in the US, and feature his ZC technology and other modifications. These mods should reduce lag and give more area under the curves.

To say I am excited is an understatement

Kind Regards



Martyn.

Well done Martyn, the car should be fantastic when you get it is finished.
Is it a lot extra to go for the RS tuning twin plug heads????

While you are fettling the bushes and drop links, I would investigate fitting GT2 rear frame mounts to reduce rear end waggle, it's not that expensive.

I look forward to a "spin" in it when you get it back

Ooh, i'm excited for you, as will VS be. Can we be cheeky and ask for a ££ breakdown, if you're not having a nervous breakdown!

CS, the twin spark does cost a fair bit more, but it will knacker the gearbox quite quickly due to the massive torque so I am told. Will investigate the mounts.

Ace, the work has cost around the same I would have had to pay to swap my car for a decent 996 turbo. Mail me your fax no and I'll send a copy of the quote across.

Thanks

Everything's crossed! Saying that, you'll probably have to wait until the summer to boot it what with the state of our roads at the moment...

Blimey Martyn - you were teetering at the top of the slippery slope holding your wallet - did someone/something push you over the edge(VMax?)?

Anyway, given that you'd decided that you needed more grunt, I think you've made the right decision to keep the sexy shape of your banana (ooer) and uprate the oily bits. I look forward to hearing more about the results of your madness! :-)

The results are in - 533 PS and 729 NM. Brilliant!!

I am almost scared to what it is going to be like when it returns.

Hobo, the car was 430 PS and 540 NM before the upgrade.
