CZCAR Posted February 17, 2004 Share Posted February 17, 2004 I have read that the l20et can be used to convert the 280zx l28e to a turbo, as the l28et's didnt come to nz i was just wondering if anyone new if this was true or not, ie swapping turbo manifolds etc over Quote Link to comment Share on other sites More sharing options...
Tony D Posted February 17, 2004 Share Posted February 17, 2004 the turbo manifold and ignition components on an L20ET are identical to the L28. The turbo has a .43 ar as compared to a .63 for an L28. I ran an L20ET exhaust manifold on my L28 for years, and eventually put an L28 turbo onto it with no problem. The L20ET intakes are smaller (runner size) so I would go for an L28 item, but the hot parts are the same. With Megasquirt-n-Spark you would be in business! Just get the L28 manifold for less intake restriction. Come to think of it now, I am actually hanging my L20ET manifold on an L28ET out of an 81ZXT, with an 82 ZX N/A Manifold (P82, non-EGR), and a 91 Stanza Throttle Body (60mm) What you have to do when using a N/A manifold on a Stock Nissan Turbo Exhaust Manifold, is to relocate the PCV valve underneath the plenum about 2" closer towards the throttle body, or reclock the turbo so the discharge is more horizontal. Otherwise the discharge piping will hit the PCV fitting. I plugged mine with a dryseal plug, and simply drilled-tapped-and reinstalled the stock PCV Valve Assembly in the same position it is on a Turbo Manifold. Easy, actually. Cheers, and good luck in your conversion! Quote Link to comment Share on other sites More sharing options...
