432-r Posted May 27, 2005 Share Posted May 27, 2005 hi, I have a 260Z and am looking to turbo charge a L28 to put in it. A mate of mine has a complete setup off an L20turbo motor,, i mean intake manifold, T3 turbo , turbo manifold, down pipe, injectors, AFM all L20 turbo fitted up to a loom and computer from a 280ZX NA. He has never run it but i think it will all work. I want to turbo a l28 motor - is this setup from the L20 turbo exactly the same as that of the L28 turbo? because it definately looks it, - or are injectors and AFM and intake manifold size (internally) smaller? I know it will bolt up easily enough but i do want about 160 -170 rear wheel kws without changing turbo size, and maybe without intercooling - at this stage. Does anyone know anything about the L20 turbo bits any help on this appreciated, Thanks, Peter Quote Link to comment Share on other sites More sharing options...
NZeder Posted May 27, 2005 Share Posted May 27, 2005 I believe the guys in Japan use the L20ET on the L28 also as far as I know on the USA got the L28ET. A number of guys here in NZ have used the L20ET in the past so yes I believe they are the same setup. Hope this helps Quote Link to comment Share on other sites More sharing options...
432-r Posted May 27, 2005 Author Share Posted May 27, 2005 thanks NZ, i thought they were the same.. I wonder if the injectors are the same.. At this stage i only have the 280zx NA AFM... Does anyone know if this will be ok with the setup? thanks Peter Quote Link to comment Share on other sites More sharing options...
NZeder Posted May 27, 2005 Share Posted May 27, 2005 I am not sure about the injector sizing - one of the turbo guys might be better to answer this one but at 800cc different I am sure that L20ET will have smaller injectors. I believe the L20ET put out 145ps in stock form where as the L28ET is more like 220ps (correct me please this is a guess). So again the injectors will be different going by these figures.

Guest bastaad525 Posted May 29, 2005 Share Posted May 29, 2005 though it can be done, I wouldn't want to stick with the 280ZX N/A ECU and wiring harness to run that setup. Better to find an L28ET ECU, wiring harness, and injectors. If I remember right, L20ET had 180cc injectors or about that? Quote Link to comment Share on other sites More sharing options...
stagefumer11 Posted May 30, 2005 Share Posted May 30, 2005 ""waves"" l20et owner here. OK All of the equipment you have will work and run on the l28e Fine. Injectors on a l20et are a factory 185cc. same rating as the non turbo l28. The only diffrence between the Turbo afm and the n/a afm is the spring tension and and the turbo has a Air temp sensor installed "boltin" If you need bigger injectors cheep, Rb20det ones bolt right in, And with tunning of the afm its runs great. Just the swap i had done on my l20et The l20et in factory form does make 145hp. Nothing great, sluggy as hell. But with mine i made 150hp at the wheels on 8psi, That was with a intercooler. Fuel pump and exhasut/intake. Not the injectors. Quote Link to comment Share on other sites More sharing options...
djz Posted June 3, 2005 Share Posted June 3, 2005 I'd be careful using RB20 injectors, they are the wrong impedance for the Z computer. They probably won't work for long before damaging the injector drivers but I may be wrong. Quote Link to comment Share on other sites More sharing options...
stagefumer11 Posted June 3, 2005 Share Posted June 3, 2005 ah, unusuall., maybe explains why all of a suddon my factory rev counter died last night. Factory rated injectors were at 3 ohms. And i know of 2 other l20et's running rb20det injectors. But id like to know what the rb20det ones are rated at, And im sure it may explain why i had to tighten my AFM to run them on boost. they are fine off boost. But now after 1 week the missing has come back. Quote Link to comment Share on other sites More sharing options...
stagefumer11 Posted June 3, 2005 Share Posted June 3, 2005 Well looks like they are high empidance, Great my luck, Will change them back tomorrow. yay! maybe ill have a late night now. Update:: Swaped back in the old injectors in 40 minutes. . Gained alot of power. and boost resonse is alot smoother. Quote Link to comment Share on other sites More sharing options...

Hope this helps Im confused, do you mean you believe the guys in Japan use the L20ET Turbo Stuff on the L28E to create a L28ET??? Quote Link to comment Share on other sites More sharing options...

Yea put the L20ET turbo stuff on the L28E and you get a L28ET - however the injectors of the L20ET and L28E are the same size so you will want to upgrade the injectors if you boost the L28E. I purchased a 83 Nissan Laurel Medalist with a L20ET so I can have the manifold, CAS dissy + the rods for a future engine build. Quote Link to comment Share on other sites More sharing options...
S15 200sx owner Posted August 1, 2005 Share Posted August 1, 2005 G'day George! Another Kiwi eh, do you have a Z or is it just the skyline? There is not that many of us on here, so good to see another one Quote Link to comment Share on other sites More sharing options...
S15 200sx owner Posted August 1, 2005 Share Posted August 1, 2005 OMG! djz, just noticed you're in NZ as well, hell this thread has a real kiwi flavour. Good to see you all here. Quote Link to comment Share on other sites More sharing options...
ZROSSA Posted August 1, 2005 Share Posted August 1, 2005 I did this to a 280zx I had about 11 years ago. Everything was pretty much bolt on. I just played with the fuel pressure to get more fuel. Little smokey of boost and there wasnt a lot of pull at high rpm but the lower rpm torque was a big difference over the NA set up. Didnt run the car for very long like this before it was written off so I cant add anything about durability. Douglas Quote Link to comment Share on other sites More sharing options...
