Building a Racecar to be Road Legal
Discussion
This is a long long way down the line but as I've started researching and designing I thought I'd see if this can be clarified.
I intend on building what is in effect a replica of one of Alfa Romeo's 155 V6 Ti DTM/ITC touring cars. As a minimum the car will be RWD (for reasons of cost and simplicity), although 4WD will be considered if feasible.
Of course, I could obtain a 155 Q4 as a donor car but as they're so rare and expensive in comparison to a FWD chassis, a conversion is likely.
To enable the conversion to take place the floor pan needs to be modified to create a transmission tunnel. There may well be a few other bits here and there, but relatively minor in comparison. There will also be new suspension mounting points front and rear, which would be incorporated into new subframes of a spaceframe construction in tubular steel.
Pretty much the only item on the car that will come from an original 155 will be the bare chassis. Everything else will either be bespoke, new or altered from another vehicle. The engine will be a modified 3.2 V6 from an Alfa GTA with well over 400bhp, maybe more than 500bhp if achievable. I already own a 147 GTA so you can see the thinking behind the engine choice as well as it needing to be a V6 anyway.
Question is, would this car end up on a Q plate if registered and how difficult would it be to obtain an IVA test certificate with this type of build? Let alone be something likely to ever see the road due to what it is.
Just after some opinions really.
Happy to post more details on the car for those interested too.
