KlassicMotion Posted January 21, 2014 Report Share Posted January 21, 2014 Post a "want to buy" ad in the classifieds. That's your best bet. http://community.ratsun.net/classifieds/ Quote Link to comment
ggzilla Posted January 21, 2014 Report Share Posted January 21, 2014 Or order a crate motor from Rebello. 2 Quote Link to comment
datzenmike Posted January 22, 2014 Report Share Posted January 22, 2014 If you want go power you need low rpm torque to move a 4x4. Face it, the 720 is a very heavy brick for a small Z2.2... but it does have 4.375 diffs in it. In Oct.'82 the Z24 was introduced... but attempting to keep the mileage, 4.11 diffs were used. The larger 2.4 can pull them but it's a struggle. If you want an easy swap that fits perfectly get a Z24. With your gears and a stump pulling130 ft lbs of torque I think you will like it. If you want a 'built' motor get a stock KA24E or DE. It will bolt to your transmission but will need some oil pan mods... and it is EFI. Quote Link to comment
Lakec423 Posted January 23, 2014 Author Report Share Posted January 23, 2014 How would I wire up the efi just switch all the stuff over from a z24 Quote Link to comment
Sealik Posted January 23, 2014 Report Share Posted January 23, 2014 How would I wire up the efi just switch all the stuff over from a z24 Z24.......... EFI? Assuming you mean TBI from the latter 720. Quote Link to comment
Sealik Posted January 23, 2014 Report Share Posted January 23, 2014 I did convert my Z24 to EFI, which came from a 1982 200sx/Z22E,... notched the Z24 head to accept the injectors It's an antiquated system and the some components started to calve...decided not to upgrade and slapped a 38/38 on it instead. Trial and 'error'....lol Quote Link to comment
HYEDATSUN720 Posted April 10, 2014 Report Share Posted April 10, 2014 How difficult was the fuel injection setup to wire and run? Quote Link to comment
