Not registered so can’t view !

It’s been a while since the planning of my new car started and the work began, but it is coming together nicely now so I thought I would post a proper build thread.

As some of you know this is my third Elise and sixth engine set up.

I’ve had a 120 bhp K-series, 190 bhp vhpd, 300 bhp Audi, 420 bhp Audi, 200 bhp vhpd, and now a 550 bhp Audi.

When planning this car I knew I didn’t want to do any of the work myself, so I had a chat to the usual suspects and while I was at JS Racing John showed me the JSR550 car, and that was that, I was sold. :slight_smile:

John spent quite a lot of time getting me a very detailed estimate together with all the possible routes I could go, and the various specifications I could choose.


This is roughly the spec I have gone for�


Engine

Audi 1.8T fully rebuilt to 2 litre spec including:
SuperTech Pistons
Integrated Engineering rifle drilled rods
Eurospec billet crank
Big port cylinder head fully gas flowed
SuperTech valves
SuperTech spring and retainers
Integrated Engineering camshaft set
ProAlloy baffled sump


Gearbox

Audi 6 speed box with Quaife slippy diff
JS Racing spec 6 speed gear linkage


Fuel System

JS Racing spec ProAlloy 60 litre endurance fuel tank with twin 044 pumps built in
Billet fuel rail
1000cc Bosch injectors


Exhaust System

Owen Developments Garrett hybrid turbocharger
External waste gate
JS Racing spec custom build turbo manifold
JS Racing spec custom build 3 inch down pipe and exhaust system with twin silencers
JS Racing spec Pro Alloy custom build inlet manifold


Cooling

Twin front mounted air to oil coolers
JS Racing spec ProAlloy three pass race radiator
JS Racing spec ProAlloy charge cooler & pre-rad
SPAL twin fans


Electrics

Syvecs ECU
JS Racing wiring loom
AIM dash with data logger
All sensors wired in to AIM dash
JS Racing spec drive by wire throttle body & pedal sensor
Launch control
Traction control


Bodywork

Built on a 2001 Elise chassis
Full Lotus Exige GT3 motorsport bodywork


Wheels & tyres

17x8 front, and 18x11 rear wheels
Yokohama / Toyo tyres


Brakes & Suspension

AP disks
AP 4 pot front callipers & 2 pot rears
Pagid Pads
JS Racing spec Nitron suspension & geo


The car is almost ready to be started now, the engine and gearbox are both completed and in the car with JS Racing spec engine mounts, drive shafts and gear linkage etc� The fuel system is completed and fitted to the car, the exhaust system is completed and fitted, the cooling system is completed and almost fitted, and then the electrics should be done in the next week or two.

The next step will be to take the car to Surrey Rolling Road where Ryan of 2bar tuning will be mapping the engine to be run in.

After that there will still be the bodywork and paint needing finishing, the wheels and tyres, and the brakes and suspension, but we hope to get the car on the road by July / August time ready for the Lotus festival at Brands Hatch.

Here are a few pictures of some of the work done so far�

I will take some more pictures in a few weeks when the car is ready to be started.

That’s all just copied straight from SELOC :wink:

Loaned :wink: A set of MO’s to see how well they filled the arch with the offset and width we had. I hate working out wheel offsets!! It makes my head hurt!!

Not very well at the moment. Its there to line everything up and work out what space we have for all the pipework and ducting needed.

Once everything is mounted, then more support will be added in the right places.

Nice work on the air inlet for the rad.

What’s with all the smudged out bits on some of the pics?

It can’t be that secret…

Looking good Greg.

Get your mits off my bloody wheels!!! :wink:

Haha, that was just for SELOC, I forgot to ask John if he wanted any bits hiding, so I did it just incase :slight_smile:

Cool, been meaning to contact you about getting a ply splitter installed on mine, as I want it properly braced, rather than just bolted to the lower edge of the clam.

Don’t waste it on them, the really Exige/JSR fans are here! :wink: :smiley:

So light it can be held up with a plastic chair!
