Do a search for the Finns, you'll get some good tire-smokin' videos and stuff to get you excited about the idea.

The later (mid-'80s) 5 and 6cylinder (602 and 603/606 respectively) are a more modern and powerful engine, and lighter due to more modern casting methods and alumunum. Depends also on what you want to spend.

The 3.0liter 603 turbo-six is a good engine and not too hard to find, watch for cracked heads (threads, search for number 14 head), the 3.5liter version of this engine is known as the "rod bender", can search for that also, not as good a candidate to hot-rod for that reason, and the later 606 version (turbod in '98) seems to be the best although harder to find and more $$, the Finns have dyno curves on their website around 450hp on that engine and close to that on the 603, would make for one smokin' hot-rod engine (literally).

Have fun, keep us in the loop.

You might look for a parts car, you can pick away at the parts until you have everything you need then, otherwise "oops, need one of those too" will getcha. The '80s 602 and 603 are essentially non-electronic engines, will run completely without 12v, although idle control is electronic it isn't required to run, just to idle well. The '90s version of that engine is a little more electronic although can be back-dated.

And sorry, we don't get "pissed off" unless you start a synthetic vs dino oil thread LOL!!
