I have one from a Chrysler Conquest. I'd rather not get rid of it, but money talks...lol
Its a front mount...looks exactly like this...
A lot of guys with Supras and stuff upgrade to them.
Also...heard a lot of good things about the Ebay turbos.
And, are you running oil and coolant through those? If you are...may want to consider an oil cooler as well.
Also, do yourself a favor and get an o2 sensor and gauge. Luckily, since you're staying carbed, you can use a narrowband sensor and it'll give you all the info you need. No need for a wideband...so, save your money there.
Should be a cool project, though....what motor is to be boosted?
