22re is a great option and buying a entire(rusted or lightly damaged) truck may be option.
While the 22re is a great plan B.
It does not hold a candle to a miata setup.
Now a running bashed(underside), stripped(project stopped), or just rusted miata is going to run you around $3500. If your willing to do some drivetrain work like head gasket etc then you may find them for 2500ish.
So miata has its own race deal. So you can run these engines standalone or build them into turbocharged beast by following exactly what others have done.
Now the frontend of a miata is setup with easy alignment and suspension adjustments. You can add a set of coilovers and you have a very adjustable race setup.
Out back you have easily adjusted IRS and a diff that can once again be upgraded or left alone depending on how wild you want to get. You can take the light car and make it lighter with a lightweight body and basically cutting out the middle of the structure placing a X frame attaching the front and rear unibody. One of those once you see the underbody you will get it. You can loose alot of miata weight easily. Just respect thats probally going to loose ridity so from a safety and ridgid standpoint adding a roll bar might be a good idea to avoid headaches.
But if your just talking a (traditional) transverse double wishbone i beam front with coil sprung solid 8.8 out back. Then just a miata engine/transmission can be used.
They are not terribly hard engines to find in cars. But partouts can be a bit harder.
Still within 10 mins I found a "turbocharged" partout. The frosted side of me to snatch this up for myself as it is 30mins away. But being 4 projects deep the whole wheat side knows I need to finish up at least 2 of those projects before starting more. So here you go a "cheap low mile miata setup" . Your local results may vary.
