s13 motor choice
i Have a 93 s13 coupe and been doing alot of research and trying to decide what motor should i swap in my silvia. So i was mainly was gonna do a rb26 swap then thought about it its gonna be ridicules expensive and if something goes wrong il be screwed so idk should i go and get a sr20 and fully build it and either get the tomei 2.2 stroker or go with a 2jz and add bolt ons and i wanted to make around 500hp or a little over for daily and street. and im plaining on spending 20 grand on the swap and what would be best
my friend just did a tomei 2.2 stroker on an s14 sr20 and he is making around 800hp at high boost on his s14.5 my friend has a profile for his buisness which is otaku garage look him up and he can tell you everything you need to know about nissans and what all you will need like i said he just it all done.
500 for a DD i'd go with the jz it'll be easier to get 500 on that then the sr. IM NOT saying the sr cant do it but it'll take more mods to do it and with more mods come more money when its time to repair it. but a 2jz swap is a good amount of money also though so either way good thing you got 20g hope its not you college fund... just my opinion though.
There is a shop out of Orlando, Fl called Carisma. Look them up they have a facebook page and they are a Nissan/Infinity RWD specialty shop. They do full rebuilds and engine swaps. If you get ahold of them and ask for a quote with the specs you want they should be able to help you out.
id go jz or ls just more reliable imo then rb's and such
id go with a jz or ls1
I'd go sr20, lots of aftermarket support. Won't hardly put a dent in your 20k haha
i would either go 2j or sr the rb is an awsome swap but there just not that reliable and they have oil consumption issues the sr you can get a shit ton of used pars (if needed) and there is a HUGE after market for it i have a fully built (stock bore and stroke) making 430 to the wheels and have no problem with it the 2jz you can get stuff pretty easy since it is USDM but it is very expensive and the 6 speed trans is very expensive and hard to find.. atleast by me...i live in the metro area. since you have a nice amount to spend i would go with the rb since it is a little cheaper than a 2jz and you can make 500+ real easy make sure you buy an rb 25 trans and use a j30 rear definitely. And like i said with the oil consumption just buy a 15$ oil cooler and a catch can you should be alright if you do go with an rb26 try not to deal with rawbrokerage.com too much they kinda suck.check out 240sxmotoring.com and nolimitmotorsports.com
RB20det all day! better then sr and you can make easy power with it. rb25 and 26 is a wast of time and money.
if you are really going to put $20,000 in an engine swap get a TB48DE engine from the Nissan Patriot. Build the internals, have someone make you a custom turbo manifold, slap a Garrett GT4780 .96 A/R on it, do the supporting mods and you now have a $20,000 engine that will smoke a Lamborghini. CAUTION!!! YOU WILL DIE IF YOU DO THIS SWAP AND YOU ARE STUPID FOR SPENDING 20K ON AN ENGINE SWAP IN A S13
Don't swap at all. New drive clean regulations won't etest you.
Simple answer, your choice. longer answer, do research. There are a lot of good threads on engine choices for a 240sx on Nicoclub and Zilvia, two great forums. I will run through the more popular motors, I've done many of these swaps myself and have driven almost all of them with various mods (except the 2JZ). First think of this though, do you REALLY want to daily a 500whp 240sx. it sounds great, I know, I built an S14 that I put 48K into with a total of 683whp at 9200rpm. I'll tell you right now, I drive it on the weekends and THATS IT. Its super fun on a canyon or at the track, super annoying in traffic and at low speeds, it has a touchy throttle, it hates going slow, it eats gas like crazy, I cant hear anything when i drive it, im a cop magnet...etc etc. I bought a Honda insight as a daily driver in the end. As far as motors go: 2JZGTE you are looking at a very heavy motor, which will change the weight ratio of your S13, the swap is roughly 6-8K done properly, and will yield between 240 to 280whp (whp is wheel horsepower in case you dont know, it is the true horsepower output of the car AFTER drivetrain loss). You will not need to rebuild the block to get 500whp but you will need substantial bolt on/ecu modifications and you will reach 20K rather quickly because 2JZ parts are expensive. RB20/25/26: all good choices, all heavy, all of them will change your cars weight ratio. None of these will need to be rebuilt IF they are in good condition (the RB20s especially are old now). RB20 is going to yield 200whp (late model ones) and will be more apt to have problems at 500whp. RB25 will put out a little more at 240whp and will need less to build than an RB20. RB26 will be slightly higher again, more in the 275-290whp and since they are newer will hold 500whp rather well as long as the motor is healthy to begin with. An RB20 is rather cheap to swap at 4-6K, an RB25 or 26 will run about the same as a 2JZ at about 6-8K. The big difference is in parts, RB20 parts are rather cheap and RB25 and 26 parts are slightly less expensive than 2JZ parts but still have a good cost to them and many have to be ordered overseas or through a company that buys overseas (not a problem but can lead to high shipping costs). SR20DET... First, at 500whp, the block will need a rebuild if you want it to last. The transmission will take 500whp but will wear down because of it. However the weight ratio of the car will stay pretty much the same and the swap can be done for anything from $1200 to $3000. A stock SR20det will yield anywhere from 160-230whp depending on what model and year (blacktop, redtop, notchtop) Aftermarket support is plentiful, parts are cheap and there are a lot of quality manufacturers that build top notch SR20 parts (this is my favorite motor by far...but thats just my personal preference, nothing against the others). lets see....2jz, rb, sr.....oh LS series motor. This is an expensive option, more in the 8-10K range for a proper swap but it is a very worthy motor. The weight ratio on the car is improved over the stock KA24DE. An LSX will be in the 300whp range (this all depends on year and type of LS there are a lot of different model LS motors). I have NOT done this swap so I am unsure how expensive or hard to find parts are....you'll have to look it up. stock KA24DE motor. great motor for a build. Since there is no swap, there is no price tag but if you somehow have a KA24E instead of DE $1000 should easily get you someone else's old DE motor (the last car I pulled a DE from, I sold it for $450 with its harness, ecu and tranny). The KA24DE will give you in the 140whp range and will need to be rebuilt to handle 500whp. aftermarket parts are good, not as plentiful as the SR but still affordable and easy to get a hold of. The weight ratio is the same as stock...since it IS stock. It can be turbo'ed or supercharged (SC is less common...I have no data on it, ive just seen it) to build a powerful and well balanced s13. Lastly, im going to add the VQ35DE motor, the 6cyl motor out of a 350Z/G35 (a few other fwd cars as well run it).The VQ will give you between 220 and 260whp depending on its year and the car it came out of. This swap is going to run an easy 6-8K. It will likely need to be rebuilt to handle 500whp long term. This is a great swap to twin turbo or supercharge but it will get very expensive very fast. The original swap is difficult since it involves changing a lot of the car both physically and electronically, making it, as stated, expensive. NOW to make any of these 500whp....you will have to mod the crap out of ANY of them. all of them will require someone to rework many of the motors systems (even without redoing the block) like turbo, fuel, air, etc. I dont know where you live but I would be surprised if a single one of these motors, built to 500whp passes smog so..think of that. Do a lot of research on what shop can actually build you this kind of motor, only a specialty shop will have the knowledge. I think that covered all the basic swaps I know of (rotary?... it can be done but I have no idea how and no data on it). All of these numbers I pulled from my head (11 years of modding 240sxs) so if any of them are wrong, someone correct me. I wrote this to give you a basic idea of what you can do, I highly suggest you do your own research for the specific swap you want. call good reputable shops, dont always trust the info on the net. If you want you can hit me up via FB, I love the Nissan scene and am always down to chat. Im based in SoCal so I know a lot of the scene around there if you're close to here..... Lord, I think this is the longest post ive ever done... good luck on your swap I hope this helps.
