MyEnquiringMind Posted September 8, 2013 Posted September 8, 2013 Hello All, Not sure how I am going to go finding one of these, but I am after an L20A L6, i.e. 2000cc L6 from Jap spec Z car... anyone with one? or know anyone with one? would be interested to know if they are easy to find here in Australia etc etc etc... Be happy with a short block if that is all anyone has... Planning a rebuild of my L24, and wanted to play with something interesting in the mean time to go into the Z to keep it going while the L24 is being rebuilt... let me know if anyone has one in their pile of bits and pieces... Kind Regards, Jarrod. Quote
dat2kman Posted September 8, 2013 Posted September 8, 2013 Mid/early 1980's Skylines had L20a engines fitted. I GAVE one away a while back. Models were four door MR or HR designation. Still a few around. Quote
MyEnquiringMind Posted September 8, 2013 Author Posted September 8, 2013 I like the price... getting to Adelaide is probably going to be the greater expense... Quote
JDSM Posted September 8, 2013 Posted September 8, 2013 From memory, Barry at Z Cars parted an base-model S130S Fairlady Z aaaaages ago. That should have had an L20E in it. That was ages ago though and I never asked about the engine. Did purchase the non-sprayer headlight buckets and am currently eyeing off a non-assisted steering rack... mmmm. Z Cars = $$$ though, haha, but never know, he is trying to downsize his collection up there. Quote
Retro Z Posted September 8, 2013 Posted September 8, 2013 Your a year too late. I listed a complete one with carbs and exhaust from a fairlady z on here for free.. but after a few weeks i just gave it all to a scrap metal guy Quote
44014 Posted September 9, 2013 Posted September 9, 2013 I think jake (D3C0Y) gave one away like a year ago ! Or sold it for nothing . Why do you want one ? It's a turd of a motor to get 2.0l all they did was reduce the size of the bore . So it's a long stroke small capacity motor . Quote
d3c0y Posted September 9, 2013 Posted September 9, 2013 Yeah i think that's nuts, probably cheaper and easier to get an L28 and then you won't want to put the L24 back in haha. Quote

So it's a long stroke small capacity motor . That's a strange way of thinking about it. The L20 ( and L20A )existed before the L24, and obviously before the L26 and L28, so they never "reduced" anything.... L20A stroke was 69.7mm compared to 73.7mm on the L24, so how was the L20A "long stroke"....? OP, If you were looking for a complete engine, it would be worth looking out for an early one rather than a late one. If the head doesn't matter or isn't needed, then a later one will be OK. I've got a couple here in the UK, but shipping costs would make it a waste of time I think. Quote

Kind Regards, Jarrod. What did you have in mind for it Jarrod? I have one in my 77 2+2 JDM import, but It's not for sale. Might try to build a destroked 2.5 one day, using my original L24 block.

I have one in my 77 2+2 JDM import, but It's not for sale. Might try to build a destroked 2.5 one day, using my original L24 block. Going off memory here but the early L20A blocks had different con rod bolt set up, compared to later (later style is not interchangable I believe). I also think the later E88 found on L20a was designed to be more smog friendly and hence less performance oriented. Earlier L20A's used a different head casting ID, can't recall for sure but I think 05L was the designated cast ID. Quote
HS30-H Posted September 9, 2013 Posted September 9, 2013 What is the difference between the early and later heads Allan? Early L20A head casting type was 'E30', which had nice small combustion chamber ( roughly same shape as E31 ) but small valves / ports, obviously. These were popular in the past as donors for performance builds, as there's plenty of meat in the casting that can be taken off in porting / flowing etc. There are better heads to start from of course, but the E30 was probably a better base to start from than some... Going off memory here but the early L20A blocks had different con rod bolt set up, compared to later (later style is not interchangable I believe). Same situation as the earliest L24s, and you'd be 'lucky' to find one that early really. In any case, you'd probably want to upgrade con-rod bolts in any new build. Quote
MyEnquiringMind Posted September 10, 2013 Author Posted September 10, 2013 Hi All, I am interested in playing with a 2000cc engine mostly for shits and giggles, the first and foremost part is my expectation that they are going to be cheaper to find etc as no one generally wants them, the reality of that decision is that I am still a broke ass student... at least until January... The big picture is that I want to rebuild my L24, the bottom end needs rings... and with that is that I will be chasing up an E31 head to go with the rebuild so that I can keep "restoring" the old girl... So I figure I already have a head that will suffice for going onto the L20 if I cant find a complete one, and the plan is to put the L20 into the Z car so that I can keep it going while the L24 is rebuilt... Thanks for the replies... Cheers, Jarrod. Quote
zzzzed Posted September 10, 2013 Posted September 10, 2013 If you rely want to be different. Then put an l20b in it Quote
NZeder Posted September 10, 2013 Posted September 10, 2013 There is a 260z 2+2 race car here in NZ that the owner was lead to believe had a stroker engine in it....the car went hard + the driver drove hard. Then after an issue with the engine it was pulled and replaed. The engine was striped for a rebuild and it was a stroker...well a de-stroker it was a 88mm bore with a L20A crank and it rev'd to 9k. Quote
Scoota G Posted September 10, 2013 Posted September 10, 2013 As far as i can figure out Jarrod wants to buy an L20 6 Cylinder, Gareth has one. Perhaps he will sell you his. I'll even go pick it up and post it to you if he'll sell it. Quote
MyEnquiringMind Posted September 10, 2013 Author Posted September 10, 2013 I have had plenty of experience with an L16 stroker with an L20B crank, ITB's etc etc... so it had crossed my mind that I would like to build a race L20A later (with the aim of doing one of those destroker motors) but first things first... getting a job... ha ha ha... Dont mind me... ill keep dreaming Quote
