Go240Zags Posted September 6, 2004 Share #1 Posted September 6, 2004 All right, I have gotten my hands on a 1983 280ZXT I am going to do some horse trading with. The body has its problems, but according to the previous owner the motor is in good operating condition with new injectors, only it is minus the clapped out turbo. I am in a quandry as putting a turbo in my Z sounds like a great idea, especially since my Series I car doesn't have its original L24 anyway. However, the wiring, etc. sounds more complicated than I might want to tackle, and I'd sure hate to see my 70-71 Roundtop carbs and E31 head not be used in my final rebuild. So, what I'd like to know is do you think it would make sense to keep the T5 tranny (to replace the 5 speed I already have) and sell the Turbo-less L28T and find a L28 with flat top pistons from a NA 280ZX? Am I on the right track here or crazy for thinking of selling the turbo motor. How much can I expect to get from selling the turbo motor? I'd let it go cheap or trade it for a good condition NA L28 from a 280ZX if the deal was right. As usual I write too much, comes from my profession I suppose. Any help you can give me would be appreciated. Also, if this is in the wrong forum section feel free to move it where it belongs. Link to comment Share on other sites More sharing options...
hls30.com Posted September 7, 2004 Share #2 Posted September 7, 2004 The turbo block is the same as the na block, the pistons, rings, head, and oil pump are different. You have everything you need,and some parts you don't. Use the turbo block and head with your 240 intake and carbs-rejet as necessary. With out the turbo, and even with-if you know that there is room between the floor and idle- the T-5 is heavy and not necessary, the other 5 speed is probably shifts much smoother.

WillIf you go this route don't forget that you will have to swap from the dished pistons in the turbo engine to flat-top pistons from a NA engine. With this in mind it may get more costly than you want...if you could find someone to trade even your turbo engine for an NA engine you would be ahead already. That is if you go this route...now if you were wanting the turbo then you are already ahead of the game and from the sounds of it only have to replace the turbo and begin the swap.

hls30.com Posted September 7, 2004 Share #4 Posted September 7, 2004 The internals do not have to be swapped, but changing them out will give higher compression.Will Link to comment Share on other sites More sharing options...
