AydinZ71

Hi! I’m trying to settle on two options. Not exactly apples to apples, but I’m focused on comparing difficulty is sourcing parts and torque capability vs weight drawbacks. Of course price is a consideration. Open to others, but so far this is what I got: 1) wolf creek racing CV shaft conversion with an R180 Subaru lsd 2) techno Toy tuning rear end kit for a r200/230 lsd sourced from various donor cars what are your thoughts? Option one is significantly cheaper, but I will be stuck with stock wheel hubs. Also not aware of the torque limitations on the Subaru lsd’s. I don’t see my plans ever exceeding 450lbs of torque.

I ran a 3” magnaflow straight-through model on my L28et at 300lb torque. Never had any problems. Was quiet enough. just installed a 2.5” dynomax on my 71’ SCCA L24 car. Quiet enough for me, but I agree upsizing if you want to run 300+lbs torque honestly I don’t know why people want their exhaust to be so loud on a Turbo equipped car. When the waste-gate opens, the entire town will hear it.

I don’t have any pics of the engine bay, but 18 years ago I finished a 71’ with an L28et. Put a custom piped Supra IV intercooler in front of the radiator and used the two circular pass-through’s tot he left and right of the radiator for the plumbing. If you are trying to avoid cutting/welding, I would either custom route your intake to just below the radiator (if the car isn’t lowered too much). Otherwise, you could keep the inline filter near the turbo and custom route some ducting for cold air. honestly I just had a 4” intake pipe 12” long with a K&N on it, just to get past the exhaust manifold. Never bothered ducting a cold air intake.

Pretty cool! Nice solution I ended up getting two fuel line check valves. One will be to release pressure from the tank, the other is for vacuum. Both have a light spring pressure they have to overcome, so they will isolate the tank up to a few inches of mercury in either direction. You can see my proposed solution @240z_restomod

@240z_restomod on IG if anyone wants to follow the progress!

Thanks! So far it looks like the floorboards and the lower rear quarter panel have it the worst. I don’t have an air compressor yet for the needle scaler, so in the meantime il be using a grinding wheel and various wire attachments. my plan is to get to bare metal, hit everything I can’t with SEM rust mort, seal it with a corrosion resistant primer, then use underbody coating spray can. any idea on how to get the unreachable spaces like inside the frame rails? They seem to have orifices, but can’t get more than a finger in there. going to por-15 most of the inside.

The previous owner reinstalled brake lights and head lights. I think I’m going to slowly work it into something more for the street. I’m not too focused on comfort since my daily driver is for that. First task is to sand/scrape all the rust and apply converter. Let me know if you have any tips! eventually looking to put in a more modern fuel injected engine. The car is way beyond stock now, so nothing really holding me back. Thinking about an RB25DET with its 5 speed.

My 71’ has a racing fuel cell installed by a previous owner. It has two fuel sending units, a fill orifice, and a simple filter breather for the vapors to escape. unfortunately, my garage Is taking the brunt of those fugitive emissions. Any idea of how I can remedy the fumes? I was thinking of eliminating the breather, and running a hose to a carbon filter canister. No idea where to start looking for one. Anyone have any clever solutions in mind? My background is thermodynamics, but fuel tanks are not my speciality.

Hi all! I bought my original 71’ in 2000, when I was 16. I had to sell the car to move across country. Now that I am settled again, I just bought another 71’. I’m not new to Z’s, but it has been a while. I was a mechanic specializing in Nissan’s back in HS and college. Now I’m an engineer working in the alternative energy industry. my old Z had an L28et with a T3/T4 and IV Supra intercooler. I did all the work myself, and intend to do so again. the one I just purchased seems to be an old SCCA racer. It has a fuel cell, complete cage, engine fire suppression system, stripped completely. Seller claims it has an R200 LSD. While I certainly recognize the R200 back there, I’m still suspicious of whether it is an LSD. its got the P90A hydraulic head, but still sitting on the L24 block. Must have been necessary to qualify in its class. anyways, just wanted to introduce myself!
