GSXR1100 WP

Is this the perfect choice for a bike-engined-car?

Plus points

Minus points

Pre Aug-95 (for WP and WR models), so no SVA emissions

Cheap (£500 covers it)

Big capacity (1074cc)

Torque

Good reputation for robustness

Power 135bhp (in bike application, WS and WT more powerful but same basic engine)*

Simple (no complex electrics, basic carburetion)

Carbs fire out the side (no problems with holes in the bonnet)

Considerable experience in sidecar groups

No big oiling problems (i.e. blackbird, gsxr1000 etc.)

Water-cooled

Not popular so little knowledge

Not popular so few bits for BEC install (i.e. manifold)

Rare (ish)

Weight (~78kg**, some new bikes ~63kg)

Old (parts availability)

5 speed (not 6 like newer bikes)

Clutch is hydraulic (good) but there maybe issues fitting the prop-shaft

*Alledgedly 210-220bhp in Steve Webster World-cup sidecar configuration.  So, pretty tuneable.
**Weighed on new weighing scales which are pretty accurate (using me to calibrate). This is whole engine with modified hydraulic clutch, minus carbs and airbox.

Various sites have data on bike engines appropriate for car installs the one that seems to be most recent is:
http://www.westfield-world.com/enginespecs_bike.html not 100% accurate, but I am hoping it will improve with more feedback.
http://www.btinternet.com/~richard.d.miles/engine.html is a bit out of date, but nicely thought out
Most things have been tried, and most things work to some degree!

One issue with these engines is that they were produced between 92 and 97.  In the UK there is a threshold Aug-95 I believe (check before you buy) where cars don't need to worry about emmisions.  So if you use an engine of this date then you can get it registered on the road much more easily.  So, to prove date you need either registration documents, or evidence from manufacturer.  It turns out that Suzuki can't age a bike from its engine number.  They need the frame number from which they can tell the engine number and also the registration details.  So, if you want to get a pre-Aug-95 then make sure you get the frame number so you can generate proof of age.  Otherwise it is catalytic retrofit, which is not any fun.
