The problem is that you really HAVE spent as much as putting an RB into the car and are gonna have all the same problems with a lot lower power cap and much harder to drive power distribution (Sad hi-comp L28 makes a nice chunk of spin-the-wheels at lower RPMS, whereas a turbo RB is a bit easier to drive on the streets). For roadrace I'd stick with the L probably, but for the streets it's a solid tossup either way. Telling the guy that an RB is a dumb idea because it's overdone is akin to telling a guy with a 240 not to put an SR20 into his car because a guy down the street has one. If that's what the guy wants, why're we against it? L series in a Datsun is boring. The same engine was in everything. I'd rather see KA swapped 240z's than L series engines with the same mods that the car had on it back in 1980. Nothing new has come along for the L.


If he wants RIDICULOUS power you are a few cylinders short. Turbocharged 350 SBC with T5 Trans and 9" diff and custom CV shafts.

Wait, are you kidding, he wants to do a FD engine for "ridiculous power"? You've gotta be kidding me. The only motors you listed he could get "Ridiculous power" out of is the RB25 and with that you'd spend so much time working on it that you'd die of old age before you got it done. If he wants "Ridiculous power" he should go with an RB26 like all the other "400hp+ or bust" idiots or a big block chevy twin turbocharged. Once he wraps his 280 around a pole or flips it off the road from being unable to drive it, call me, I'd love to see if I could salvage parts off the car.
I feel you on that, but you can put a later model turbo engine in it and make good power pretty easily with the L28. You live in east cobb and own a Z Car? Have you heard and/or seen the "Gumby 240z?" He kept the L28 and that car is ridiculous, and it is set up for road courses.

And LOL at putting a 13b in a Z Car. That is the dumbest shit I have ever heard. I can see it in a 510 (even though I would never do that to mine), but a Z Car? That's laughable.

And the RB20 is nothing but a boat anchor. I wouldn't put that in anything.
