Skib Posted December 5, 2009 Report Share Posted December 5, 2009 well for starters youll need... sawzall BFH (big fucking hammer) welder swapping in an L6 will require a lot more fab than its worth Quote Link to comment
65dodge Posted December 5, 2009 Author Report Share Posted December 5, 2009 i know that it is a lot of work i do that type of stuff every day building hotrods but i am wondering if it would be worth it perfomance wise Quote Link to comment
Skib Posted December 5, 2009 Report Share Posted December 5, 2009 i know that it is a lot of work i do that type of stuff every day building hotrods but i am wondering if it would be worth it perfomance wise with an L24, no. a used L24 will be putting out ~100whp... probably less.

65dodge Posted December 5, 2009 Author Report Share Posted December 5, 2009 ya but that is stll beter than the 67 hp out of the j13 and it would be a 5 speed insted of a 4 speed and better runing gear Quote Link to comment
Skib Posted December 5, 2009 Report Share Posted December 5, 2009 If you want to do a swap and get more hp go with a 4 cyl L series like an L20b or an new 4cyl like the KA24 or SR20det. All plenty capable of over 100hp and much much higher and require only a small amount of fab work. with the amount of work its going to take to fit an L24 in there and get ~100hp you might as well drop in a SBC instead Quote Link to comment
65dodge Posted December 5, 2009 Author Report Share Posted December 5, 2009 that coast money and the 240 motor is free Quote Link to comment
Skib Posted December 5, 2009 Report Share Posted December 5, 2009 If you want to put it in go for it, youl be the only one with an L6 520 and we love seeing crazy rats. But its going to cost you more in the long run than an L4 swap IMO Quote Link to comment
65dodge Posted December 5, 2009 Author Report Share Posted December 5, 2009 k well i will just keep updates on my truck then i am only in the truck $400 and it it pretty straight Quote Link to comment
Skib Posted December 5, 2009 Report Share Posted December 5, 2009 you should post in introduction thread with some pictures of your truck :thumbup: Quote Link to comment
Cuts metal like mad Posted December 5, 2009 Report Share Posted December 5, 2009 I say do it. Shit... I'm ready to see something different. :lol: L24 isn't that bad... hell, mine did easy burnouts. (tires, not the motor HAHA) Quote Link to comment
Steroid Posted December 5, 2009 Report Share Posted December 5, 2009 Welcome and Let Er' rip ! ! ! I seem to remember years ago on either this forum or the "old" one, a truck with an inline 6. It seems that I remember the radiator was mounted in the bed. BLEACH????? You remember that one? Anyway, good luck. Where are You located? Quote Link to comment
yellowdatsun Posted December 5, 2009 Report Share Posted December 5, 2009 Putting a L-6 into a 520/521 is a really crappy swap. The motor doesn't even remotely fit. If you use the stock motor mount locations not only will you be cutting the firewall, but you can't fit a radiator anymore either. So the option then is to hack DEEP into the cab, keeping in mind the whole intake manifold will have to go in too. Plus you'll be moving the tranny crossmember, and shortening the driveshaft. So you end up with a truck that's hacked up bad, weighs too much in the nose, and is still slow. Your "free" engine swap will end up costing you a lot of money by the time your done. So if you're willing to do all that work, you may as well put in something a lot better than an L24. Even a chevy 350 is a LOT easier to fit in one of those, because it's shorter than the L-6 Quote Link to comment

Cuts metal like mad Posted December 5, 2009 Report Share Posted December 5, 2009 With all the people cutting up their 510s to fit intercoolers and the associated piping, and the 520 being worth less than a 510... why the fuck not. Move one cylinder behinde the firewall, cut the core support so a radiator can be push closer to the grill. It'll fit. Through in the 240z rear suspension. Sounds like fun. Don't expect the 50/50 weight distribution the 240z had though, but if you look at a certain other 520 build, it is possible to get close... but with the straight 6, you'll need some ballast I'm sure.

Put the Rad. in the bed. intake will still be in the way of the master cyl. etc.:( maybe a VG30 and transaxle from a Maxima in the bed..... oh damn, now I need another truck, and a doner maxima..:D:lol::D Edited December 5, 2009 by greybeard Quote Link to comment

yellowdatsun Posted December 5, 2009 Report Share Posted December 5, 2009 Regardless of the cost/worth of the truck and engine, it's still the worst possible swap you could do in one of those trucks. Way more effort, for absolutely zero gain. Quote Link to comment
thisismatt Posted December 5, 2009 Report Share Posted December 5, 2009 Why would anyone go through all the trouble to replace a totally outdated drivetrain with a totally outdated drivetrain? If you're going to go IRS, at least use something modern with discs, CVs, and a fresh diff. The same for the motor... Quote Link to comment
1sad521 Posted December 6, 2009 Report Share Posted December 6, 2009 will the old 240 IRS fit in a 520? didnt think it would... i dunno dont have a 240 to measure Quote Link to comment
Charlie69 Posted December 7, 2009 Report Share Posted December 7, 2009 I am thinking you will have to kick out the back cab window to shift. Bad Idea. Save some money, hell you will save money by not doing the swap just in welding supplies.:lol: Quote Link to comment
1971Datsupra Posted December 8, 2009 Report Share Posted December 8, 2009 all the above is mostly true. yes the intake manifold will be close to the master cylinder, yes the nose will be hevier, yes you will have to cut into the fire wall, yes you will need to move trans cross bar and shorten the drive shaft. Now I bought my 521 for 300 bucks, i now have over60 times that. it all adds up and i'm sure i'm forgetting something. but in the end you will have a one of a kind. put it this was I also have a 1998 mustang cobra (stock)i raced my truck against it with my brother driving the cobra, it was a door to door race up to 100mph. It's cheaper to buy a fast car then to build one. Just not as fun. It's your truck, time, and money, have fun with it Quote Link to comment
