CZCAR Posted March 2, 2004 Share Posted March 2, 2004 Ok first it bears mentioning i live in NZ where no l28ets were produced. i have a stock as hell 1980 280zx, with a N42 head and n42 block, it came from japan in 87 if that matters, i also have a l20et. which is a 2 litre turbo l6. Ok what problems am i going to run into by bolting the turbo manifolds of the l20et on the l28, they will fit. Is my compression going to be to high, I am looking at buying a l28 turbo manifold of Ebay, and a p90a head but id rather not if possible. So can i swap it over. What else will i need to change, remember swapping in a l28et is not a option. It costs about the same for one of those for a rb20det $1500.

jp 280 Posted March 2, 2004 Share Posted March 2, 2004 im in newzealand as well, i brought my L28 with l20et manifolds on it, when i pulled it apart there was no internal damage or problems that could be seen, it was running with the N42 head, im sure it had standard injectors and the standard ecu. Ive been talking to Andre from Speedtech motorsport and he said there should be no probs with the compresion. Im no longer using the standard manifold, turbo, ecu and injectors. if your interested in any of the bits im not using let me know. later jeremy Quote Link to comment Share on other sites More sharing options...
CZCAR Posted March 2, 2004 Author Share Posted March 2, 2004 Did you run it using the l20et turbo ecu? What are you running now, what size turbo...custom manifold? im intending to upgrade the turbo and injectors. can we buy any parts here like custom fuel rails, anyone bring anything in from japan, any any info would be great thanks Quote Link to comment Share on other sites More sharing options...
Mack Posted March 2, 2004 Share Posted March 2, 2004 I would not worry about compression. The N42 block/N47 head should have dished pistons, giving it an aenemic compression ratio of 8.3:1. The turbo specific L28's had a retardedly low, even for a turbo, cr of 7.4:1. You should be fine putting the L20ET turbo exhaust manifold on the N47 head. although I wonder if exhaust runner daimeter is the same or not, I know intake isn't. as far as the ECU, if you dont plan on running a lot of boost, I knwo people hbere in the US run the NA ecu for simplicities sake all the time when swapping into an early 280Z. I hope this helps.... McAdam Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted March 2, 2004 Share Posted March 2, 2004 The n/a intake manifolds off the early FI Zs work well for a turbo setup as well. I'm using the N42 on mine, and there is very little difference between it and the turbo ZX intake. Quote Link to comment Share on other sites More sharing options...
jp 280 Posted March 3, 2004 Share Posted March 3, 2004 Did you run it using the l20et turbo ecu? What are you running now, what size turbo...custom manifold? im intending to upgrade the turbo and injectors. can we buy any parts here like custom fuel rails, anyone bring anything in from japan, any any info would be great thanks It was using the L28 ecu, i dont have my engine running yet but has a Garrett GT3540 turbo mounted on a Trust stainless manifold, i have a piece of blank motec fuel rail which has a good shape for running o-ring injectors, came from aus through andre at Speedtech. I have been bringing all my own parts in from japan, prices here are far to expensive. later Jeremy Quote Link to comment Share on other sites More sharing options...
CZCAR Posted March 4, 2004 Author Share Posted March 4, 2004 Hey how are you bringing the parts in, are you going over there. Or got contacts, anyway you could hook me up, obviously you can take a fee if you want. Just out of curiousity, worth asking i thought umm thanks cameron Quote Link to comment Share on other sites More sharing options...
