ThePog 8,122 Posted October 20, 2020 Report Share Posted October 20, 2020 Any of youse knowledgeable about bolting a turbo onto a diesel NA 80 series land cruiser? My sis has a majestic shitbox nearing 500,000k and it runs sweet as a nut, manual as well. We had a talk about boosting it to 1hdt spec using factory stuff but I am not sure how well it would take it or of there were significant differences between the NA and turbo versions. Whatcha got for me? Quote Link to post Share on other sites
jessemk2 1,203 Posted October 20, 2020 Report Share Posted October 20, 2020 You mean 1hz? Piston tops on the 1hz are bit thin so will fail with to much boost 1hz+t you dont really go past 5-6 psi to keep them semi reliable Think safari used to do a bolt on turbo kit They are pretty slow so any boost gona help 1 Quote Link to post Share on other sites
Yowzer 35,314 Posted October 20, 2020 Report Share Posted October 20, 2020 Nah, 80 series has NA 1HDs in them. Couldn't tell ya what the difference is between the two but I'd slap a turbo on it and send it and assume the best. Quote Link to post Share on other sites
ThePog 8,122 Posted October 20, 2020 Author Report Share Posted October 20, 2020 Fuck I just assumed it was a 1hd, I will carjam it and find out Quote Link to post Share on other sites
jessemk2 1,203 Posted October 20, 2020 Report Share Posted October 20, 2020 Hmmm All the factory non turbo diesel 80s ive seen have been 1hz 2 Quote Link to post Share on other sites
ThePog 8,122 Posted October 20, 2020 Author Report Share Posted October 20, 2020 It's a 1hz. Quote Link to post Share on other sites
Yowzer 35,314 Posted October 20, 2020 Report Share Posted October 20, 2020 Oh bummer. Yeah, probably not worth boosting soz. Not without whipping in some better internals anyway. Quote Link to post Share on other sites
ThePog 8,122 Posted October 20, 2020 Author Report Share Posted October 20, 2020 Yea probably not. Fuck TD42s are pretty great then. 1 Quote Link to post Share on other sites
Yowzer 35,314 Posted October 20, 2020 Report Share Posted October 20, 2020 5psi will still at least give it a little gain, so if you can get a cheap enough kit ya may as well. Dunno what the fuel limit on these engines are though so you'll likely still have to.be conservative with the smoke screw. Not like a dirty old 3L that'll take 30psi and a maxed out fuel pump and love it. Quote Link to post Share on other sites

Yowzer 35,314 Posted October 20, 2020 Report Share Posted October 20, 2020 Give it half a turn on the smoke screw. Quote Link to post Share on other sites
jessemk2 1,203 Posted October 20, 2020 Report Share Posted October 20, 2020 1hz will do 1 million kays no worries They still have them in new 70 series in africa cause they run on dodgy diesel and can fix bush mechanics stylez Just drive it for what it is Quote Link to post Share on other sites
ThePog 8,122 Posted October 20, 2020 Author Report Share Posted October 20, 2020 Yea that will help a wee bit.. 1 Quote Link to post Share on other sites
Yowzer 35,314 Posted October 20, 2020 Report Share Posted October 20, 2020 After half a mill the injector springs and fuel pump will be pretty well flogged if they haven't had a rebuild, that alone will make a world of difference. Quote Link to post Share on other sites
kpr 6,505 Posted October 20, 2020 Report Share Posted October 20, 2020 This is the same shit, just minus a cylinder. 50% more power on 8psi boost, with a wind on the pump. no intercooler, stock airbox. just adapter r to stock manifold and some pipes. 1hz looks to be the same deal 2 Quote Link to post Share on other sites

nzstato 2,887 Posted October 20, 2020 Report Share Posted October 20, 2020 4xoverland on YouTube has a bit on turbo a 1hz. A few dos and a lot of don’ts... run light psi and get and EGT gauge. Thin crowns easy to pop and overheat if not careful. Result was general improvement open road driving 1 Quote Link to post Share on other sites

I drove it over Mt Messenger a few weeks back and if dealt with it as you'd expect, slow but unrelenting. 2 Quote Link to post Share on other sites
