talking to someone today, apparently you can just use the staza cross-member and itll all bolt up too, handy because i want stanza struts too, so now to find a stanza.....

I have done engine development to my 120Y from A12 through A15 to L18.

I used 610/710 crossmember, short L-series tranny from 160J which bolts in with(gearstick in right place after reversing stick F4W63, bented gearstick from 160J) tranny holder from B310 Sunny which needed little modification to holes, but was easy job to get all 4 bolts fit, and A10 160J propeller shaft which is perfect match to H165, only Centre Bearing support is something that I couldn't find where to get original, instead I modified 180B's to fit, 120Y's original bolt holes are much wider than 180B.

Something I tried to tell but didn't accomplish, there's two kind gearboxes to L-series engines, short and long ones, long ones need to centre tunnel modifications if used in 120Y, short boxes instead are perfect match without any modifications.

I used pretty wild L18 with 45 Dellor'tos, modified A87 head and about 340 degree cam with .65" valvelift, that produces about 180HP at 8500rpm and first time it gets traction it breaked wishbones so I replaced those with 160J wishbones, which are little too long and absolutely too rigid, and they still bent far too much under acceleration( those installation needed custom made king bolts). Have to do someday somekind shelby-rods. Also that H165 is too weak but I haven't found any good replacement yet.

Oh, I also take whole streering linkage and box from 180B, and also conmpele strut assembly from 180B( Actually I bolted everything under hood from 180B), it fits fine in with big coils, towers get tight only when increasing caster.

I also got brake booster from 810 180B as it sits directly in firewall letting more space to carburators, there's some lack of space with LHD machines.

I'll get some pictures ( that 120Y is nothing to be proud of except handling and power) when I get some digital camera to my hands.

That's case with B310 120Y. Pal of mine did one, it can take all from that Stanza (160J model a10 here in Finland), even that H165 with fourlink bolts right in. You don't need anything but wrench to do that conversion. Oh just L18, L20B is too tall, even with short L-series there's need to cut hood's strengtening to get it fully closed.

I also have one factory new Stanza X-member, with B210 120Y X-member mounts come to outer edge( there's own holes for A-series & L-series X-member, that L-series come about 3" longer from firewall), in B310 & Stanza they are middle mounted, so they can't be swapped.

From '75 to '77 120Y model is B211, I'm actually not sure which type x-member it uses.

So i cant use the stanza crossmember for a b210 120y???

Quote:

Anything can be used, but for B210 it is much easier to use 610/710/810 crossmember as they bolt straight in. I think that 910 crossmember can be used as well, and with that you also get rack & pinion streering.

That Stanza x-member is just like B310 120Y's original with L-series engine mountings, and B210 x-member differs from it only about those mountings to car body which are wider. It's quite easy to transfer those L-series mountings to B210 x-member but it even easier to use 180B x-member. Engine mounts are also pair to x-member mounts, Stanza and 180B mounts are different and in most cases can't be cross used.

There's tens of different lower control arms to Datsuns, and with L-series in 120Y it's good idea to use wider control arms to get some negative camber to compensate understeering coming from heavier engine. I used those 180B arms which results about 1,5 degree negative camber instead of original 1 degree positive, and as I also increased caster as much as there's space in towers and that 120Y with heavy L-series becomes almost neutral, which is great as in standard form 120Y understeers like a cow.

L-series engines have at least two kind of oilpans, and with 610/710 x-member you have to use rear type pan and with Stanza x-member front type pan. If you are planning to convert B210 to L-series it's highly recommened to get some spare car with L-series engine and rigid rear axle as almost everything can be moved to 120y.

cool thanks heaps!!!

any other tips for anything else on the car?

actually also, is the 120y fuel system and electrical system good enough for an l-series or is there any other mods that would have to be made when putting the motor in?

Quote:

Those are pretty fine, you only need fuel return line if you want to use fuel-injection or be sure that gas won't boil.

You also have to cut radiator frame to get enough room for radiator, I used Stanza (a10) radiator as hoses are just opposite way in original radiator, and that L-series engine also makes quite a bit more heat than A-series. 180B radiator is little bit too tall and need some extra modifications if used.

in the pic L18_B110, you say i need the sump and oil pickup, whats the oil pickup?

basically, if i use a 180b crossmember i need 180b sump and if i use stanza crossmember i need stanza sump, is that correct?

Quote:

It's the thing which supplies oil from oil pan to oil pump.

Quote:

Yes.

yep, that's right. The oil pickup is just the screened pipe that bolts to the bottom of the block and goes into the sump to pickup the oil.

And as naukkis said, you will also nee the 180B engine mount brackets (on the block).

naukkis seemed to cover pretty much everything else well. I just added the photos cause I had them lying around.
