Possible Project 260/280z V8, thoughts
Since parting out my car ive been thinking about my next project for when i get my school stuff payed off and get a better job. What I want is something that I can auto-x, targa, and which lays down some power in the straights as well. Doesnt need to be competitive in any racing class, just fun and has parts available for fairly cheap if anything breaks or needs replacement. So after a few weeks of pondering, i decided an obd2 chevy LT1+T56 (cheaper than LS1 and easier to find) swapped into a datsun 260/280z would be a good direction. I would try to find a chasis 1975 and older to get out of cali smog issues as well. That way I can remove all smog equipment and basically do what i want.
Ive considered newer chasis options like rx7, porsche 944, and 300z, but smog regulations and parts availability and/or price make me hesitant. Carb regulations aside, an rx7 chasis would be preferred, but it would require getting the car checked by a ref and then subsequent smog checks as well.
So does anyone have any ideas about other avenues I should look into? Engine, chasis, etc ... any input would be greatly appreciated as I am looking to not spend tons and have a car that doesnt have to be trailered.

IMO do a 240/260z. At the local dyno day there was a 240z with a 280z turbo swap, stock internals/turbo, making 330whp.
Sounded like a really cheap and appealing project. Although v8 is always best.
best of luck to you, make sure to keep us updated if/when the next project arises.

As a track car, they'll also suffer from similar issues of old cars that need to be addressed- like chassis rigidity and small brakes. The newer cars you listed won't have those issues.

qft- friend of mine had the same and tracked it reliably for ages. Just keep in mind that those cars are a lot older than the oldest Miatas and will come with most of the problems that old cars have unless it's already taken care of.

I think the V8 is a good idea, but I'd prefer to drive the turbo straight-6 personally.

I've seen this car in person and at the track, and it ***** on the chests of the gays:
Mark Rolston's RB26DETT Powered 240z | Auszcar
MZM International Inc. - Mark Rolston's 71' 240Z

Do a little more reading on the LT1's. You'll probably want to go OBD-I as it's actually an UPGRADE for OBD-II cars to switch back to OBD-I. Makes life a little more simple.
I love the instantaneous torque of my LT1. It's fun.
Cool thing about those old straight-6 cars is their rear ends! Most will come with a 4:10 or better... and w/ an LT1, that's just absurd. Even in stock trim I was barking 3rd on a $130 AutoZone clutch during SCCA events. Then I got full exhaust, tune, CAI, and destroyed a throw-out bearing while powersliding 2nd into 3rd gear at 5:30am on my way to work. I have a pic of that thing somewhere.. and yes, I'm a jackass.
Did I mention the LT1's are fun?
EDIT: Meant to mention about the gearing... LT1 6-speed cars came with 3.42's. With a 4.10 I've seen guys light up 3rd gear on the highway.
EDIT: Pics are always nice.

a '70 240Z was my dream car. I originally was looking for one of these when I bought my Miata. Unfortunately any of them I looked at would have need a full ground up restoration because of the issue these cars have rusting out. And each of them had had a hack job repair to cover up the issue. So even if it looks to have a good body, it's probably all glass and bondo under, where the frame rails are supposed to be.
It's a big project, this is what you would probably be in for. 1971 Datsun 240z resto.project [vids/pics] - HybridZ

I see what four plus years of sitting outside, undriven has done to this Miata I have now and can't fathom the amount of work a car twice it's age would take. And most of it stuf I don't want to do it, which means it'll cost me. It would be worth searching/waiting for a clean example to come up and paying the price IMO.

Here's a project car for you...
1973 Porsche 914 V8 chevy 350 conversion SCCA ralley race car
v8 swap 914.
Also swapping Miata running gear into an older British or Italian car might make an interesting project with good results. Spitfires come cheap.

maybe L33 would be better, I mean a car that spins on throttle in third is getting out of fun and into scary territory. Less power also means I can run the lighter 240z chasis as they had rigidity problems as stock, but can be stiffenned up with frame rails and roll cage. Ill look into that motor, thanks jake
Porsche with a 350 would be sweet, but i fear the cost of replacement parts and difficulty finding parts at a junkyard. I know about the rust issues, i fear it as well and fully anticipate to strip the car down completely upon recipt to look for and repair rusting panels and to apply new finish to the metal under the carpets and whatnot to further prevent rust. Obviously rust would eventually take the car, but I dont plan to live forever either and I am ok with that.
OK im going to check out those links you guys posted up.
