240hoke Posted October 8, 2002 Share Posted October 8, 2002 Okay heres my problem. I am putting a 280zxt engine in my 74 260z and am wondering what to do with the engine managment. I made the mistake of purchasing an engine without the distributor, wiring harness and ecu thinking i was going to go w/ sds but now im rethinking the whole deal. so heres the two options i figure i have: 1.) Go ahead with the sds(or other managment system) to have a really good platform to build on as i moddify the engine in the months to come. This would take care of the distributor coil ect also since i would get the 6-f sustem. But since the SDS system will run me $1500 i will be forced to put the engine in pretty much stock as im trying to keep the whole deal under 4k. This would probaly be the most trouble free and give me the flexibility as i up the boost and add bigger injectors etc. 2.) Find an ecu, wireing harness, distributor, coil, etc, etc, and etc from the zx and swap it in, i figure i could get away with this for rather cheap giving me money to add stuff now like an intercooler, injectors, and better driveline. But i will then have to figure out how to get the stock stuff to run this(300zx ecu?), i dont know anything about the stock stuff so i would need some help in this area. Im open to any ideas since im just now building the engine. so far it has had a full rebuild(head: bead blasted, springs, valves, comp. 3 angle valve job. the block has new bearings, cylinders honed with new rings, water pump, oil pump and all seals.) any advice on what to do about engine management or any thing that would help me out period would be appriciated. btw i do more than my share of searching the archives and reading people sights, so please dont be smart.

randy 77zt Posted October 9, 2002 Share Posted October 9, 2002 i have a 77 with 81zxt .the wiring took more time than bolting in engine.go with sds.you have the possability of wasting much time tring to troubleshoot old nissan parts.plus investing a small amount in something that will need to come out soon if you upgrade.i have to smog mine since i live in ca.just put the sds in with new mercedes injectors.do not use old injectors.the money you spend on flow testing and cleaning is best spent on new injectors.if you run old injectors and you a 1 %30 clogged you will sieze a piston.if you can get on a chassis dyno you can tune the sds to run cleaner at cruise speeds and make more power.i am not a tree hugger but unburnt fuel out the back= wasted money.
