Virgin builder

[stillabiker]

Not just a virgin builder but a virgin poster so please be gentle with me.

About to start a build but only as a track day car. Can't be bothered with DVLA et al!

I have found a XR4i less than a mile away. I assume that this is not a new idea so would ask if this is an OK unit for a track car. I am a little concerned about weight. Will this affect the balance of the car? Also is the running gear suitable or will I have to find another doner car for that.

As an alternative, has anyone used a Jaguar engine V6 or V8?

Thanks for any help you may give.
