what engine mods can u do to the lb20

single or dual 45mm webbers, extractors, if you have an independant rear end datsun take the front diff out off a 720 and replace the rear with it (far better ratio) my L20 has a racing cam in it but before that went in it still went pretty good.. makes a huge difference from standard.

I've seen a video on YouTube of a man who has a turbocharged L20b engine... It's pretty stout... And I wanted to know a thing or two... Where would a man find a race cam or a mild cam, what type of exhaust do you run, and, where would be a good place to find a hood, front fascia, and fenders for a 79 620???

I run a U67 head, with 442 cam (mild street) with 280ZX valves, 510 outer springs , roadster inner springs. Dual SU's .1979 200sx electronic Dizzy. Lower end is balanced. I also run twin 9" electric fans and 105Amp alternator. Mated with a 280Z 5 peed, and a roadster 2L clutch (very hard to find these days. Also run a 68' exhaust manifold, to a 2 1/4 pipe . Works dependably, i don't shy away from trips over 2000 miles.
