cntryboy_88 Posted January 19, 2016 Share Posted January 19, 2016 So I have a 98 with the 3.3 and yesterday I found on Craigslist a 2001 3.5...the guy is gonna sell me the motor tranny and wiring harness/ecu for $500 so I'm pretty stoked about it is there anything more that I would need to make this swap work other than those things?

XPLORx4 Posted January 19, 2016 Share Posted January 19, 2016 You'll probably need both the tranny control module and the engine control module. 1 Link to comment Share on other sites More sharing options...

cntryboy_88 Posted January 20, 2016 Author Share Posted January 20, 2016 Get the whole thing if you can...then you're not missing anything.I won't be able to...he is using it as a parts car as well for his other pathfinder he just doesn't need the motor or tranny Sent from my SM-N920V using Tapatalk Link to comment Share on other sites More sharing options...
cntryboy_88 Posted January 31, 2016 Author Share Posted January 31, 2016 Picking up this engine tomorrow if anyone wants to keep up with the status of this is will be in the "Betsy" build Sent from my SM-N920V using Tapatalk Link to comment Share on other sites More sharing options...
cntryboy_88 Posted April 18, 2016 Author Share Posted April 18, 2016 OK just to help anyone out on here who decides they think they might want to do this let me stop you now! Lol I'm mid build on this and it was not a good idea...yes I'm going to love my power difference once it's done and yes I will get it done but not before completely removing every wire on the whole front half of this truck...nothing matches up from these 2 engines and to get everything you need the whole truck has to be completely re wired and it's a pain being that I don't have a donor truck sitting in my driveway Sent from my SM-N920V using Tapatalk Link to comment Share on other sites More sharing options...
kdj Posted April 18, 2016 Share Posted April 18, 2016 I've had my '98 3.3 and my '03 3.5 parked side by side before to compare the differences. It looked like it would be a challenge to say the least! Link to comment Share on other sites More sharing options...
DarekG Posted April 18, 2016 Share Posted April 18, 2016 Sounds like a worthwhile upgrade, that's a 100 horsepower difference is it not? Link to comment Share on other sites More sharing options...
Cuong Nguyen Posted April 18, 2016 Share Posted April 18, 2016 There's only one guy that has done something similar in nature but it took him many years. Link to comment Share on other sites More sharing options...
Rebelord Posted April 18, 2016 Share Posted April 18, 2016 Sounds like a worthwhile upgrade, that's a 100 horsepower difference is it not? 198 vs 245ish. 265 rated in the cars. I own both. Tell ya what. Real tempted to ditch the 99 for a 02+ just because of the 3.5. Sent from my SM-G920V using Tapatalk Link to comment Share on other sites More sharing options...
cntryboy_88 Posted April 18, 2016 Author Share Posted April 18, 2016 Sounds like a worthwhile upgrade, that's a 100 horsepower difference is it not? It's not quite 100 but yes the power difference will be nice but for the money I've got into this truck would have been easier just to buy one with a 3.5 already in it Sent from my SM-N920V using Tapatalk Link to comment Share on other sites More sharing options...

I know someone with the 3.3L and they told me they don't feel safe passing vehicles uphill and such because it feels so gutless. His is auto and mine is 5-speed so maybe that has something to do it but I drive very calmly most of the time. Link to comment Share on other sites More sharing options...
kdj Posted April 18, 2016 Share Posted April 18, 2016 Sounds like a worthwhile upgrade, that's a 100 horsepower difference is it not? My swap went from 3.3 168 HP to the 3.5 at 250 HP (82 HP difference). I parked the '98 and bought a '03. It cost $3000 and I didn't even get my hands dirty plus I have about two tons of spare parts. The '03 makes the old '98 feel like driving a hay wagon and the front end isn't rotted beyond repairs. The extra 82 HP sure is noticable. Yes I can now pass people.

Matt86 Posted May 10, 2016 Share Posted May 10, 2016 Have you got this swap completed? I got a 3.3 in my 2000 and it's amazing shape. Motor is well gutless and sounds like a bomb. Got a 01 with a 3.5 complete. Low kms and runs like new. Just wondering what has to be changed to do the swap. I know the ecu, ignition, use the 01 keys, engine wiring harness. Does all the mounts alighn proper and transmission from the 3.3 work? Thanks for any advise. I know it's a ton of work to swap but I'm willing if it's decently reasonable Link to comment Share on other sites More sharing options...
cntryboy_88 Posted May 11, 2016 Author Share Posted May 11, 2016 No Its not completed...litterly every wire has to come out of the car with a 3.5 nothing matches up...the transmission wiring goes into the main dash harness same with the 4x4 wiring...ignition wiring runs into the engine bay it's different abs wiring is different which is in the dash harness you have to reolace...everything! Nothing is the same and I'm telling you now it's not worth it...I'm thinking about finding an 01 and transferring all my lift just so I don't have to rewire everything Sent from my SM-N920V using Tapatalk Link to comment Share on other sites More sharing options...
Matt86 Posted May 11, 2016 Share Posted May 11, 2016 Ok thanks for the info. Still might tackle it. Done lots of Honda swaps and engine builds Link to comment Share on other sites More sharing options...
vg33deguy Posted May 11, 2016 Share Posted May 11, 2016 Man I really want to do this but it sounds like I'm going to want a small army to help get it done fast. May want to get whole donor from the sounds of it. Sent from my iPad using Tapatalk Link to comment Share on other sites More sharing options...
Matt86 Posted May 11, 2016 Share Posted May 11, 2016 I bought a 01 to do the swap. I have a 2000 in amazing shape. Zero rust which for where I live is impossible. im going to attempt in within a few months. I'll keep everyone updated with the swap and build Link to comment Share on other sites More sharing options...

cntryboy_88 Posted May 12, 2016 Author Share Posted May 12, 2016 That's the best way to do it is have a donor...I'm about to buy a junk one Sent from my SM-N920V using Tapatalk Link to comment Share on other sites More sharing options...

Guest punkrawker Posted June 28, 2016 Share Posted June 28, 2016 any updates? Im glad im not the only one who noticed the 164 to 250hp from 3.3 to 3.5. and has been wondering if this swap was possible or not myself. Link to comment Share on other sites More sharing options...
cntryboy_88 Posted June 29, 2016 Author Share Posted June 29, 2016 I almost had all the wiring needed...you will need a donor 3.5 truck for this...then I went to get my 3.5 donor for $400 and it ran fine so I swapped all my parts...you literally have to rewire the whole thing Sent from my SM-N920V using Tapatalk Link to comment Share on other sites More sharing options...
Guest punkrawker Posted July 1, 2016 Share Posted July 1, 2016 by rewire you mean just run harness out and connect to what they need to be connected to? no cutting into stuff? time consuming yes, i dont mind running wiring harness if its all there, its the trouble shooting and splicing into things that were once working fine i dont like doing Link to comment Share on other sites More sharing options...
