showa Posted September 4, 2009 Share Posted September 4, 2009 Picked up a 240z that has been sitting for 20 years. Previous owner said it ran when parked with this motor package. 280Z Block 240Z head Cartech Turbo Holley 4 Barrel Carburetor 4 Core Radiators Electric Fan Thats all the details I have until I pick it up next week. Any advice on prepping the turbo to try a startup ??? I've neve had one before and don't want to smoke it if I can help it...

yetterben Posted September 4, 2009 Share Posted September 4, 2009 Make sure the turbo still spins you might want to pull the coil wire and crank it to get the oil flowing again. Make sure the engine is not seized. Chances are the turbo should be chucked in the trash though. I dont know if they used waste gates back then. I know the old ray jays did not and they would boost to crazy numbers. Quote Link to comment Share on other sites More sharing options...
ozconnection Posted September 4, 2009 Share Posted September 4, 2009 That's a long time to be sitting idle. I would guarantee a fuel leak with the carb...either internally and/or externally. Pull it off and do a thorough rebuild with a kit etc. It's not hard, just consider it essential! Replace all the fluids as well....and flush out all of the old fuel and replace the fuel filters. I see a good couple of hours work before you get too excited about starting it. Cheers and good luck. Quote Link to comment Share on other sites More sharing options...
turboHLS30 Posted September 4, 2009 Share Posted September 4, 2009 I have a cartech turbo kit and I think it has a wastegate attached to the plenum Quote Link to comment Share on other sites More sharing options...
Guest Rolling Parts Posted September 4, 2009 Share Posted September 4, 2009 "Ran when parked" makes you wonder WHY they parked it. Chances are 100% that the engine "ran" but had serious problems which caused it to be abandoned for 20 years. The last 2 cars I did not buy had the same spiel of "running when parked" but after 16 years they were complete trash. Do the basics of oil change, ignition system inspection, pre-oil the camshaft, swap fuel and change the fuel filter, new battery, radiator fluid, etc, etc and just give it a try. Seriously there is nothing to loose if you swap fluids and it inspects OK. I hope you get lucky. Quote Link to comment Share on other sites More sharing options...

ahhsumzx Posted September 6, 2009 Share Posted September 6, 2009 Wait... how is the engine turboed AND carbureted??? Quote Link to comment Share on other sites More sharing options...
240z!!! Posted September 6, 2009 Share Posted September 6, 2009 Wait... how is the engine turboed AND carbureted??? easy exhuast pushes turbo, turbo is fed into carb, carb is retuned to suit the turbo....a search would probably bring up a page or 2 of posts and cars Quote Link to comment Share on other sites More sharing options...
turboHLS30 Posted September 6, 2009 Share Posted September 6, 2009 LOL and it's that simple Quote Link to comment Share on other sites More sharing options...
Ineptitude01 Posted September 6, 2009 Share Posted September 6, 2009 Worth considering doing your oil change full synthetic. Whatever's been done to that turbo, it basically can't not appreciate some good synthetic oil, especially just as far as getting oil on the bearings before it actually spools at all. Definitely also worth taking the turbo off just to eyeball it, and maybe even to measure the shaft play. On two of my L28ET's, I've had the PO's assurances that the turbo was rebuilt, and in one case, it obviously was, but they still oil starved it after the rebuild and blew the damn thing right back up.

showa Posted September 6, 2009 Author Share Posted September 6, 2009 I am a big believer in sythetics............I prefer to use it in all the drivetrain.... Ineptitude01, thanks for the tip on shaft play, hadn't thought of that.... Quote Link to comment Share on other sites More sharing options...
JSM Posted September 10, 2009 Share Posted September 10, 2009 The BIG question in my mind is WHERE has it been parked for 20 years! In a low humidity garage? Outside in the elements??? Good luck! This was a rust free 280zxt when parked outside in Orlando for 16 years! Quote Link to comment Share on other sites More sharing options...
showa Posted September 11, 2009 Author Share Posted September 11, 2009 WOW!!!! It's been in a Nevada Garage most all that time as far as I know....Thank God... Quote Link to comment Share on other sites More sharing options...
Avernier Posted September 11, 2009 Share Posted September 11, 2009 my car sat for 16 years under a tree in a back yard... no rust besides the passenger floor pan, and the battery tray and the bottom of the hatch. but the motor started up with a new fuel pump, filter and plugs. vroom vroom!!!!!!!! best of luck.

Yokohama Posted September 15, 2009 Share Posted September 15, 2009 Reminds me of the Ford Pinto with a Spearco Draw-though turbo kit installed. I did not even know that they had made a kit like that until I saw it. Quote Link to comment Share on other sites More sharing options...
Yokohama Posted September 15, 2009 Share Posted September 15, 2009 Also, I like to spray in some penetrating lube (like PTFE type, etc.) and keep that up for a few days and then hand crank it over a bunch while having someone keep spraying in lube (via spark plug ports). Also be sure to look at the cam; I have seen ones rust severely over long term storage. Quote Link to comment Share on other sites More sharing options...
showa Posted September 17, 2009 Author Share Posted September 17, 2009 Thanks Yokohama.... Marvel Mystery Oil and hand cranking have been happening....We'll see what tomorrow brings with gas/spark applied..... Quote Link to comment Share on other sites More sharing options...
JessZ Posted September 18, 2009 Share Posted September 18, 2009 When I bought my 83et motor three years ago it had 120,xxx miles on it. The turbo is a t3. The turbine had a little play in it, but since then I have had not one problem with the turbo or motor. I just change the oil regularly with conventional and run it hard.
