That is a quality job, congratulations! And your car looks really mean, like it can back up the stickers and wing

The dizzy physically will not fit. But as far as I know, the electric sensor inside is the same - and the slotted wheel fits inside a 280ZXT dizzy, as well as the wiring harness.

Yep. Pull-N-Save. There have been 1 or 2 of the cars per week, at least last year when I was pulling them. Any Tbird turbo, Cougar turbo, Mustang SVO or Mercur XR4TI has them - make sure you get the ones with the brown tops.

I made 300hp with stock injectors and the Z31 ECU (stock fuel pressure, nothing fancy). That's crank hp (assumed driveline losses for 260 rwhp), and I was starting to run lean on the top end. I expect to make a bit more now with just 6 370cc Merkur injectors ($7.00 each) and my MAF installed in the larger intake. I also got an adjustable FPR, and will need to run about 45 psi fuel pressure. So far it's running smoothly, and I just need some time to ease up the boost to confirm everything is kosher. That should be a SAFE 350hp with stock electronics, and possibly upwards of 400 hp for 350 rwhp.

It's a Top End bar. I have the rear one too. My signature has my best E.T., my best mph is 107 (on street tire tires). Yes, a stock '86 Z31 turbo computer, with the MAF sensor installed in a larger intake.

Thanks. I had to create a new account - seems like with the new forum look there, my old login "SleeperZ" was taken. Check out my fuel system photos under "Sleeper78Z"

I'm having good luck so far with 370cc injectors using my Z31 computer. I've upped the boost to 12 psi so far, and it is driving as well as it did with the stock injectors. What I did is not plug and play, but you seem to have an ambition for tinkering like me. I cut out the MAF element and installed it in a 3-1/2" intake pipe, then bumped my fuel pressure to 45psi. What I am currently planning on doing is adapting the MAF from the Z31 to support 370cc injectors, and sell them, just like Granatelli does with Ford stuff (a recalibrated sensor for larger injectors.) Then folks won't have to fab a new intake. Conceivably this can work with larger injectors as well, like 420cc and 450cc; this should just be a component change in the MAF.

I agree. You could be saving that Z from an untimely demise by keeping from someone who may just be an idiot and wreck it.

Aux - that's a pretty tall information order. A/R is the area/radius ratio of a turbine or compressor housing. In such a housing, the area/radius around the snail is a constant. Radius being the distance from the center of the housing to the center of the passage, and area is the area of the passage at the point you measure the radius. The higher the number, the greater the flow potential for that particular series of turbocharger. For a turbine, the A/R is directly related to the spoolup time, or response of the turbo. I don't know anything about turbos on rotaries, but what I see people using are larger A/R turbines. As far as compressors, you need to determine your power needs and calculate the flow and boost pressure necessary to support that. Based on that and what type of driving you will do, you can then choose your turbo, both turbine and compressor.

Right on! Can't wait to hear the results of the road tests

Yes, the stock diameter is close to 25". 195/70/14 and 205/60/15 are stock tire sizes - I believe the diameters are around 24.9".

Yeah!!!! That's it!

Not that I would actually be caught driving that, but I think it looks kind of cool. It reminds me of the popular cartoon hotrods I saw in magazines growing up, with the caricatures of huge engines and tires, and the monsters driving them with eyeballs and tongues sticking out...

Nice going! The guy is better off now - he needs to learn lessons the hard way, and the consequences of running afoul the law can be a good teacher.

Looks nice, just like mine I'll be posting pics of mine, with my new intake and exhaust (driveshaft loop too), as soon as I can figure out how to post a webpage - I hate Earthlink and their stupid tools! Woohooo! My 1000th post!

That is a waste of a perfectly good 240Z. Stickers and wings...sigh.

Almost right The punchline was 12 second timeslips I bet the same problem exist for the Cadavelier as for the Supra - TRACTION! It only gets worse for a FWD car.

That is just wrong. I see it all time. But put the rest of your fears to rest - they do have separate tanks - I know. My old Toyota knocks like crazy on the regular 85 octane, but only occasionally on the 87. I put 89 in it 2 weeks ago and had zero knocking.

I had a guy from my local Z club telling me some Subies came with the R190, LSD to boot. I have checked EVERY Subie in the scrapyards more than once, and I've NEVER seen anything bigger than an R160 in the Subies. AWD just doesn't need the stoutness of an R190, and I don't believe any came with them. Even the wife's '98 Outback has an R160 LSD, tiny little thing...

Definitely post results on how it fits and works when you get it. I'm trying to get an idea of which TO4E compressors fit without spacers, as I don't want to redo my exhaust when I upgrade my turbo (just installed 3" mandrel bent with Scottie downpipe and Dynomax muffler).

For your climate I would think 75W80 would be fine unless you do more road racing than street driving. A synthetic like Red Line would certainly help the shifting if you really wanted to run something like a 150 weight...

It depends on what the AFC expects to see on a throttle signal. The Z31 is like the Z and ZX, just an idle signal and a full throttle signal. At worst, just get a TPS from another car that does provide the right type of throttle signal. I think it wants an RPM signal, taken from the -COIL.

I can't believe it fits! That is sooo cool!
