ROGUE TROOPER Posted April 20, 2008 Share Posted April 20, 2008 Can the 90/110 2.5L 19J Turbo have its turbo taken off and converted to a N/A? Ta Quote Link to comment Share on other sites More sharing options...
ciderman Posted April 20, 2008 Share Posted April 20, 2008 Can the 90/110 2.5L 19J Turbo have its turbo taken off and converted to a N/A?Ta IIRC the TD had different pistons lowering the compression , I may be wrong though The N/A lump was a stronger unit Quote Link to comment Share on other sites More sharing options...
Les Henson Posted April 20, 2008 Share Posted April 20, 2008 Different part numbers for the N/A and TD, but I suppose you can fit non-turbo pistons, but at around £50 each it's not going to be a cheap conversion. You will also need to blank off the oil flow/return that was previously connected to the turbo. You can keep the Turbo injector pump, but the spill rail pipework will have to be altered. Les.

Personally, I wonder if the pump will supply too much fuel, even though it has a boost pressure sensor which will detect 'low' pressure. There again, I see Les has practical experience. Cheers.

Phil Hancock Posted April 21, 2008 Share Posted April 21, 2008 I have compared NA & TD pistons and they are dimensionally the same. But they are materially different. Quote Link to comment Share on other sites More sharing options...
