I want to ditch the TBI in my new toy(97 nissan 4X4) Not sure of the best way to do it. Will smog be an issue? Can I just take the intake man.+ the fuel rail and injectors? Do I need the whole head? Would it be a better Idea just to swap a DE. Thank You.

swap in a DE? Should be a KA engine....its not the DOHC ? SOHC from '97? wow

Startours7 · 03-09-2004, 02:06 PM

Yes it's the SOHC. It's funny, got the same valve cover as the pignose, but it's got that stupid TBI with that ugly round airbox. I kind of wanted to stick with the SOHC because 1. I here it's better for N/A upgrades (turbo is a bad thing for 4X4's IMO) 2. It's only got 70,000mi.

Thats cool,I wasn't trying to diss it or anything....I was just wondering.....I don't really know anything about the SOHC,but I'd ditch that TBI,too if I had it....

Beleive it or not, but the 2004 hardbody's have a DE with TBI!

You're talkinb throttle body injection? Are you sure?? Shit, I thought throttle body injectors went out in the 80s. . . :P I'll need to take another look at my dad's d21

gogeeta13 · 03-09-2004, 10:34 PM

here, from the auto show

It was listed as 143hp/154tq. KA24DE.

deviousKA · 03-09-2004, 10:40 PM

90+ d21 (hardbodies) in the us came with multi point fuel injection. The throttle body looks like a tbi, but there are 1 injector per cylinder (94+ trucks have side feed type injectors, older ones and the ka24e in the other vehicles used top feed). The z24i which came in the earlier d21's have tbi with 2 injectors.

as far as a good offroad engine, i would stick with the ka24e, and possibly try out a few different cams. The truck ka24e cam develops the most power at the lowest rpm.
