so, my comments after yours.....

I've been watching a lot of the old Group B rallies and I have a big itch to build a rally car. Those screaming motors flinging dirt and dust all over the place. drool...... I've had other cars, but never something purpose built and wild like a rally car. I know RWD cars are not the best, truthfully they are probably the worst, but for me it's about the build and having fun. I have some ideas on cars, and build plans but I'm looking to pick the hives brain before I plunk down some hard earned cash on a project car. I have money burning a hole in my pocket for a purchase right now, but I want to make a wise choice.
What I see the car competing in:
- Hopefully a $20xx challenge. I'd like to say 2019 or eve 2020, but realistically life might get in the way
- Local RallyX and AutoX - there is a difference between a rally car and a rallycross car - specifically cage, safety stuff, etc. Just to be clear ;)
- TN Gambler if I can purchase one cheap enough
What I think the car should have:
- RWD yes
- small lift likely "no." Most of the fastest rallycross cars are not lifted (there are some exceptions). Plus most older RWD cars already sit pretty high. Stock-height Miatas do fine, stock-height e30s do fine. Lifting a car that doesn't need it just screws up your center of mass. Remember, rallycross courses are made so STOCK class cars can do them without any real damage. Just get a good skidplate
- lots of lights I mean, nothing wrong with lights but for rally-x no need (few are at night), so it's just extra weight. I take most of my rally lights OFF the car for rallycross (only for stage rally night stages).
- manual clearly
Things I don't know:
- LSD? preferable, yes. RWD cars with open diffs will lift the inside rear and lose traction.
- Welded rear? in general, no, unless you can't get a car with LSD
- Turbo? very few turbo RWD cars do well in rallycross. Lag is your enemy. Heat is your enemy. Complexity is your enemy. Rallycross you can only use so much power in 2WD, traction-limited. a 300hp RWD car will not beat my 130hp RWD car in most cases.
- motor swap? depends on the car
- I assume easier to start with a running car? always
- roll bar construction? or kit? (never had one of those except in a Jeep) no need for rollbar for rallycross or autocross unless it's a convertible (with hardtop). It's just extra weight.
My skillset concerns:
- time. I can do more now that my kids are older but time is always a factor. My kids will help out when they can. I sympathize
- welding. I don't know how, but not sure I will need it. Avoiding a car with rust would be a bonus. really no need to weld unless the car is structurally unsound.... you will need a skidplate though.
- electronics. Maybe my weak link in car work. I can do it. I wired the 3.2 motor into my 911, but it definitly t akes me a lot longer than anything else. Which goes back to that time issue. what electronics do you need other than stock stuff?
I have some cars I like, but like I said I'm curious what the hive suggests.
for what you want to do....e30 and e36 are the easy button and very competitive even in stock form. e36s are cheap these days. Miata of course, but you need a hardtop for rallycross, which could blow your budget. Volvo 240s are solid though not terribly fast at rallycross without a lot of work.
Here's the entry list for modified RWD at our last event. This is one of (if not THE) most overall competitive MR class in the country in my opinion, so here's an idea of what cars are fast. Vaugn Micchie's Porsche 924S not shown since he's from New England, but it's also fast.
