Steering rack on a tuscan for what car does it come

[kurtsti]

Does anyone know from what car the steering rack comes original or is this an original TVR part

TVR part only

I was told some of the internals BL Rover dont know if its true, but it would sound normal for TVR to cast the body and "steal" the rest

Same as just about every other manufacturer does if at all possible... A completely bespoke rack represents a serious tooling investment and is unjustifiable if existing components can be used. Most manufacturers will go to a tier one supplier such as ZF or TRW and ask them for a rack to meet certain specifications. The tier one will come back with a proposal and cost, based upon utilising parts they already manufacture where possible. All manufacturers have to consider costs vs. performance benefit. To be honest, TVR if anything tried to do too many bespoke parts for their cars (from a commercial perspective). The T cars are no more "parts bin" than the likes of Porsche and Ferrari and a lot less so than others (Bentley, Lambo, Ford era Astons etc) and don't deserve the 'glorified kit car' tag that the ill-informed like to use to describe them. Unfortunately all this bespokeness cost a lot of money that might have been better spent elsewhere (such as the electrics...)

I'm looking a LHD steering rack to convert a RHD to a LHD that way I'm asking the question and it seem this rack aren't available at the moment so I looking to that en rack from a donor car

If a company like Ford was to use a steering component from a high volume ford car on a sports car or even on brand like Jaguar they own (at the time) this is completely different to the
likes of TVR,

In the case of the Tuscan, having a hub assembly from a Jeep, rear brakes from a Ford, power steering pump from a Peugeot, Differential from a Holden coil pack from a Vauxhall
door mirror from VW ball joint from Saab, Jaguar and rack parts from a Rover

So for me dropping a Corvette engine in seemed to top the job off

[NorfolkSteve]

OP, as the rack housing (casting) is TVR unique, you will not be able to source the parts to make a LH drive rack from another brand / model. You best bet would seem to be to try and get one from a TVR breaker if new parts are no longer available.

Otherwise you might just have to get used to RH drive...

Having spent the last 20 years in the engineering design of new vehicles for most of the worlds major manufacturers, I can assure you that they all use "off the shelf" components when possible. Engineering completely new components when an existing part is available and meets the required specification is expensive and all manufacturers work to very tight business cases for new models.
The only difference is whether TVR bought the parts direct from the tier one supplier or another manufacturer, although this is also not uncommon.

All of the parts that you have listed are parts that manufacturers buy in from suppliers rather than engineer themselves. The level of bespokeness is usually the minimum required to meet the spec requirements and package constraints of a particular model.

As for putting a GM engine in your Tuscan, this is very much in keeping with commom practice for mainstream manufacturers, see this link http://www.honestjohn.co.uk/forum/post/index.htm?t=14874 for a bit of an insight into which manufacturers put others peoples engines in their cars.

Interesting....how are you going to get the steering shaft past the exhaust manifolds...?

[kurtsti]

I've now ordered a billed custom steering rack and it will pas the manifold the same way like on the original LHD cars

[The Surveyor]

The factory LHD chassis had an extra guide tube passing through the chassis top rail to enable the column to be routed past the manifolds, it'll be tight otherwise!
