Didn’t see an introduction section so I’ll do a brief one here; I love British cars, currently have a Discovery and an F-pace (my DD). I used to have an XJR which I absolutely loved and a Defender but I sold them :(. I am experienced in building cars but am in no way an expert, I am based in Lodi, California.
A friend of mine does track days with his 350z and keeps asking me to come with him, I have an ITB Miata that I could take but I’ve grown bored of that car to be honest and was looking at my options for building a Jaguar track day car.
I could go with an XJ-S and get the Jenvey ITB kit, or could go with a newer XJ, something like an X300 or X308 but the security systems and electronics on those have me concerned, or could go with an older XJ series 1/2 and get the Jenvey ITB kit.
Benefits to the XJS are the LSD and I could find one with a stock 4 speed which would be nice, also the Jenvey ITB kit. I’m not really too concerned with power as I am with suspension/tires/etc. What are my suspension/brake/tire and wheel upgrade options like with the X300 or X308 and XJS? I’m assuming I could run something like a compushift transmission controller on the 300/308 instead of manual swapping since the manual swap parts don’t look too easy to get. Can I disable the security systems on those? I could always LS swap whatever I buy which would probably be the easiest thing to do but Jaguar motors are cool lol.
This car would be a track day car and maybe the occasional car show, it will not be driven on the streets and will be registered as such so I’m not worried about emissions or interior components.
