Alvaro’S D21 Posted April 10, 2019 Report Share Posted April 10, 2019 Hello everyone, I’m new in this forum.. I’m looking for some help, about 94 Nissan D21-240sx intake manifold swap Quote Link to comment
datzenmike Posted April 10, 2019 Report Share Posted April 10, 2019 They both have to be KA24E engines. The '94 D21is. 240SX could be eitherKA24E or DE. If both are KA24E then they should swap just fine. 1 Quote Link to comment
]2eDeYe Posted April 10, 2019 Report Share Posted April 10, 2019 You need the manifold, wiring and ECU. 1 1 Quote Link to comment

KoHeartsGPA Posted April 10, 2019 Report Share Posted April 10, 2019 Any particular reason for the swap? I'm just curious.. 1 Quote Link to comment
KoHeartsGPA Posted April 10, 2019 Report Share Posted April 10, 2019 Maybe something like this https://www.ebay.com/itm/Fits-89-94-Nissan-240SX-S13-Sr20Det-Silvia-Intake-Manifold-Plenum-/362584089607 so that you don't have to deal with ECU and wiring swap? Not sure if it has been done here on ratsun... Quote Link to comment
Alvaro’S D21 Posted April 10, 2019 Author Report Share Posted April 10, 2019 🙄😩😫it’s really hard all this... but I try to explain.. 1- 240sx throttle sensor have 2 plugs. D21 throttle sensor have only 1. 2- 240sx IAA unit have 2 plugs. D21 IAA unit have like 5 inches of wire each thing, but they go to a single connector. 3- 240sx Air regulator where Is going... I have pics but I don’t know how post in this place Quote Link to comment
]2eDeYe Posted April 10, 2019 Report Share Posted April 10, 2019 You will need to host them online somewhere like imgur or postimage. 1 Quote Link to comment
KoHeartsGPA Posted April 10, 2019 Report Share Posted April 10, 2019 I'm still having a hard time understanding the reason for the swap, if you're having issues there a plenty KA D21 in JY all over, so finding parts is not an issue, my 93 D21 has 276k miles and runs like a champ. 1 Quote Link to comment

]2eDeYe Posted April 11, 2019 Report Share Posted April 11, 2019 If you open the picture in its own window, you can copy image and then paste it here in the reply window. Looks like you just need to throw the d21 junk away and get the 240 stuff 😄 1 Quote Link to comment

Alvaro’S D21 Posted April 12, 2019 Author Report Share Posted April 12, 2019 Maybe.. so you show me your king cab Datsun with ka24de 1 Quote Link to comment
Alvaro’S D21 Posted April 12, 2019 Author Report Share Posted April 12, 2019 Thanks guys I’m going to do the swap this weekend.. if I have problems, I let you know guys, because still I need your help Quote Link to comment
bottomwatcher Posted April 12, 2019 Report Share Posted April 12, 2019 Your going to have problems if you are trying to do an entire intake swap. So much easier to fix what you have. I have the 89 240sx on my 95 truck ka. I did this for the stand alone harness on a swap. Manifold to head ports don't match well and have about a 16th inch sealing surface on one them. It does look cleaner but you will be chasing parts for a manifold only offered for two years nearly 30 years ago. Let us know how this turns out. 1 Quote Link to comment

bottomwatcher Posted April 12, 2019 Report Share Posted April 12, 2019 Yeah I daily mine without issues but the port match bothers me. (I guess I have issues!) I do have a car head that will swap a truck cam into "someday" and clean things up. He is about to tackle the wiring which has stumped a lot of folks into giving up on their truck, anyways I guess have at it. Like koHeartsGPA said why? I am curious too. Quote Link to comment
KoHeartsGPA Posted April 12, 2019 Report Share Posted April 12, 2019 My head just exploded, what do you mean by port not matching?, I used a KA24e out of a 96 d21 and the complete intake, harness and ECU from an 89/90 240sx, I had 0 issues with matching up the ports, they both have the same intake manifold gasket....my swap is in a 77 620.

bottomwatcher Posted April 12, 2019 Report Share Posted April 12, 2019 They bolt up just fine, they just don't match very well internally. If you get a ka full gasket kit off ebay it will probably come with two different gaskets. One for the truck head and one for the car head in the kit. At least that is what I got and hold the gaskets together. The bolt holes are perfect but the intakes are a different shape. If I remember the cooling passages were perfect. Anyways it has been a while but it was one of those things that bothered me the ports were not the same shape. Maybe I got an oddball but I bought an entire engine from a 1989 240sx for the intake and power steering pump and other bits and brackets that cleared that manifold. Put it on a 1995 truck engine one area had me scared it was so narrow it might not seal but it has held up fine. Pulled the car head to be rebuilt one day and dropped the rest of the block at the scrapyard. These were used engines so maybe something else different about the heads. I just know they were not a perfect match Quote Link to comment
KoHeartsGPA Posted April 13, 2019 Report Share Posted April 13, 2019 I got just one version in my kit and everything matched up on both sides, head and manifold, that's why I'm confused. Quote Link to comment
