I am a new car owner plus brand new to Z's. I have a 1977 280z with a restored L28E. i like the engine but its slow for me. I wanted to know if a RB26DeTT swap is A: good for gas mileage B: a more reliable engine C: the best Nissan engine i can put in there. If so are there any details on swapping the motor cause I'm doing it myself. And where can i find one that is in good condition and doesn't look sketchy. I want it to be a brand new engine but i realize that's not possible. Any info would help me Thanks.

Your better off putting in an l28et. The rb series engines are no more reliable fhan the plain old l series but they weigh alot more.

I would have the original engine rebuilt and consider installing a 240Z E 31 head. In SCCA GT 2 specs in the 1980s, we were getting almost 300 hp out of this set up. Of course you will need headers and a 2.5" to 3" exhaust to get the engine to breathe.

I would consider an Sr20 swap. it is a 4 cynlinder get good gas mileage. mine puts out 400hp at the wheels and runs a 1/4 mile at 11.70. the smaller engine also sits back behind the front tires, so it is better for weight.

      280z Disc brake conversion

      By Jeff G 78 · Posted

      I'm still waiting on a hoist to free up before I can start bolting the new brake parts on my Z, but I did make the drill jig today.  I started with a 12mm thick Mustang wheel spacer with a pilot.  I then made a drawing to layout the holes needed.  I transfered the drawing onto the spacer and I drilled three new 1/8" holes through the jig (spacer) so I'd have the correct 4x114.3mm holes.  One hole is shared from the original 5 lug rotor.  I then bolted the jig onto the Mustang rotor and simply dr

      Looking for a 1978 280z Gas Tank

      Local radiator repair shops used to be plentiful but getting harder to find.  Some of them just specialize in big truck-heavy equipment radiators.  I will be needing to do the same for my project.  I have heard good reports on gas tank RENU but there are none of those franchises in my area.  Good luck, John-Lugoff, SC

      Decided to go with the 240sx conversion. Main reason is it’s strictly for the street and the parts were easy to source. What I didn’t realize was the 14” wheels won’t clear the caliper. Now looking for a set of 4 lug 15” rims and tires I can use during the build process. Can anyone recommend a temporary solution as far as make and model preferably a steel wheel that I can use until I’m ready to buy the wheel and tire combination at the end of the project? Thanks again for all the help out there.

      There are several reasons to use the S197 rear brakes.  The rotors are larger diameter than the SVO rotors and they are vented.  The calipers have larger pistons to give them more power.  The big beef with the Maxima rears is that they don't offer as much stopping power as the stock drums.  The S197 rears allow the addition of an adjustable proportioning valve.  The Maxima rears cannot utilize an adjustable prop since the prop needs to be all the way open to get close to enough rear bias.

      Any particular reason to use S197 Mustang 5-lug brakes?  The Fox body SVO Mustangs had rear discs with 4-lug.  It's a popular swap to use SVO or T-bird Turbo Coupe rear brakes to retrofit discs to other Fox body Mustangs.  These parts are still pretty common (probably available as a kit).  Might be worth checking to see if they'll fit.
