im in nz as well, i brought an L28 with the L20 setup on from a wreckers ($375nz) just gonna bolt the bottom end back together today, and if your keen on spending some money on that engine you can look into parts from HKS, Trust and JUN however these are really expensive so buy them straight out of japan where posible. but for the price for a nice stainless turbo manifold you could buy yourself a RB26 to drop in there.

or if you know anyone in japan you could buy from the japanese auctions, i saw a stainless turbo manifold on there for $200nz

 

im being different and sticking with the L series and buying all my parts out of japan, but bang for buck swap the engine.

later

Hey, I'm down in Christchurch :)

This is one R30 I've seen around, its got an L20 turbo in it

But this is the one you want, the Iron Mask (this is one in Japan)

 

I've got a manifold off an L20 turbo, I had a chance to buy a whole engine minus turbo for $150 too but decided not too.

 

They have a strange inlet manifold and from what I could figure out the throttle body is just round on the inside and only a single "port" not like the Z ones. The sump is at the wrong endso you have to get the Z one modified. They have a different idle control (like the US Zs) yeah, they go pretty well though, I guy I know had one that was imported from Japan with a HKS turbo kit on it and it was pretty fast till he blew it up.

 

I've got the turbo manifold with an R32 GTST turbo on it and a modified sump for an L28 sitting here if somebody wants to make me a decent offer :) also have two whole L28s in pieces.

Hey guys,

 

I'm also in NZ, i've got a 260z 2+2, and am currently sorting out a transplant for it. i have the option of getting a complete r30 skyline turbo car complete (with good 5 speed box) for $150!!!. i have no idea what these engines are like for extracting some decent numbers out of them. i know that the intake side of things could be easy improved as they aren't intercooled and have puny turbo to throttle body pipework. i'm not sure what sort of diff these cars have too, i'm hoping that it has a LSD which i may be able to swap into my 260. I've heard that it was a constipated engine too, so i think i may just go with an RB 20 det.

But then how hard is it to fit an L20et into where a L26 has been???

 

Cheers guys

fitting a l20et into a z, well ive been told its a hard job to do, something about the gearbox mounts ect and the gearbox itself.

 

it easer to fit all the l20et stuff onto the l26 :)

 

anywayz , here in nz are ya ?

 

the diff is a R180, possibly LSD not sure tho, how do you test ?

 

getting a l20et with gear box for 150?, i would presume that your near otaki, as. lol i was looking at that engine also. well most of his cars. just need some time to get over there :( (dr 30kits) :)

 

improveing the l20et isnt a hard job, yes i have been told that they are hard to get power out of, currently i have a Turbo off a Rb20det to bolt on, they bolt right up apart from you need a custom dump pipe, or a stock Rb20det one. and fitting a water feed line to it : /, im not sure how to do that.

 

a Rb20det thorttle body bolts up to the L20et, and need only minior mods for it to work :), and some boring inside the intake :), since its larger.

 

intercooler. well, thats easy. ive been told that a l20et is quite happy running 10psi at the turbo (stock turbo) and will not ping :)

I'm going to look at a Laurel tomorrow, the guy is asking $500 for it, slight panel damage to the R/R and its dereged but its a 1981 L20 turbo 5 speed limited slip, I'll let you guys know about it tomorrow, I'm thinking it'll probably be a CV joint R200 rear end.

 

The L20 shouldn't have any trouble mounting up to a Z gearbox, I've seen it done before.

 

The R30 Ironmasks are one of the coolest looking cars ever

I ran the l20et turbo set up on a 280zx I had about 10 years ago. A real cheap and nasty conversion. It wasnt hard to do. A bit of making up new air inlet pipes, exhuast and mucking around with the fuel pressure regulator. I never had it runing great but it was a different beast to the standard l28. The turbo spooled very fast but ran out of puff quite early so it kind of had the driving characteristics of a good turbo d. truck. I never ran more then standard bost and had the stock compression ratio.

 

I dont know how long it would have lasted. The car was totaled a few months later. :(

 

Its good to see so many Kiwi's piping up. Mabye when we get some of our projects going we should meet up?

 

Cheers

I ended up buying the Laurel for $370NZ, the gearbox is very good, it turns out its not an LSD (its a 3.9 R200 though). Been mucking around with it a bit, lots of little differences between the L20 and an L28, the throttle body is even smaller if you can believe it. I've swapped over an L28 inlet manifold onto it with some L28 injectors (anybody have any idea which are bigger out of the L28 and L20 turbo ones), it has a bit of a miss around 4 grand and doesn't seem to pull much over 5000 which is a bit disappointing.
