NO TURBO: what is the best all motor...motor?!
 

Whats going on guys, just a general question for my s13 coupe. I dont want to have to deal with turbos because i know more about older cars and pistons, valves and mainly just motor shit. What would be the best all motor motor i can work and put in my coupe? Just took the tranny out to put a better one in and want to actually start up my build. My car has a KA24DE fron an s14, advice is appreciated!!!

If E85 is Available the area. High Compression is the way to go..

LsX

End thread

If you want to keep it nissan I would go with a SR24VE build, they have been proven to make 300+ whp on 93.

Go with the 350z engine, VQ35.

f20.........

Ls motor. Cam, header, intake, and tune and you have a beast.

One of my original plans was to go ls but i dont know if i have the money with how much the mounts will cost along with engine and trans, but if i get a good deal i definitely wanna go ls. But on the other hand i wouldnt mind staying nissan, and i've read a million and one bad things about jdmenginedepot.com and all those sites, so where could one find a good nissan motor? :zombie:

Vq or Ls:hitit::hitit:

How much you think i could get a VQ with a tranny for?

If you don't have that much money, I don't sugest a N/A build. They can be alot more than a simple turbo set up.


but.. If i was going N/A Id do a vq35 high comp. Or a 1uz.

how much power do you want? ive seen the kits for KA's that make 250hp with stock injectors and ecu for around $1,500 i think. upgrade your fuel system and get a tune bam youl have a fun little car.

99% sure now im gunna build the KA thats already in the car, its a strong motor never drifted so i might throw money into doing forged pistons camshaft valves bigger injectors. I already ordered an N1 exhaust coming next weekend, and have a walbro fuel pump to install. I think i'd be happy with a set up like that for a little bit.... does that seem like it be a reasonable set up with a decent amount of power????

Reasonable yet.
Decent amount of power, no.

KA is a truck engine, nissan fitted it for the US market because you guys tend to drive for a lot of miles, and they needed reliability which could not be attained with a turbo CA or SR. Dont expect power from this engine, unless (yes) you turbocharge it.

VQ v6 or LS v8

The VQ sounds WICKED if done right, can be made very responsive but will not come close to any LS variation power wise... the chevy small blocks are also very compact and fit ridiculously in any engine bay...

1uz sounds great but makes shit for power.

LS v8 if done right would ultimately reap the most benefit.

VQ would be something on more of a budget but STILL will end up costing tons...

The only Vehicle the KA was put in before the 240sx was a Minivan in Japan. There were several cars it was put in before it ended up in trucks.

It was put in the 240sx because the CA18/SR20DET made more power than the NA 300zx and Nissan USA did not want it to compete with it. The CA18/SR20DE was thought to not be peppy enough for the US.

If your statements were true why did they bring the Z31 over with the turbo motor?

The KA's head flows horribly and the long stroke make it less than ideal for a NA build.

If you know about old piston motors. The LS* series would be ideal. Push Rods and all.

NO replacement for displacement. Can't go wrong with any LS variant. I personally stay away from the VQ swaps since all the ones I have seen have the oil pan sit really low. Plus you can't beat the sound of a nice hot cam V8.

Having been in the NA scene with my S14 for awhile, I would say go the SR20DE route. I nearly bought the motor below before finally putting DET into it just recently.

Had all sorts of tweaking, Nismo 296 duration cams, extensive head work, Jun bottom end, circa 250PS easily.

If your on a budget, stick it out with the early S13 SR20DE; Pulsar N15 N1 pistons, high lift cams, extensive port work. Nismo N2 4 throttle kits are still popping up used here and there but mind you will have to switch over to airflow less CPU.

Ill be going back to S13 with this sort of build down the road. Totally regret tweaking the S14, just a heavier car and not true to N2 racing routes as the S13 was.

thank you. i cant stand it when people call it a "truck" motor. it didnt start life that way.

TBH i could not care less. I dont care where it comes, the KA24DE has nothing to do under the hood of a sports car, it just is a reliable engine with no power.

You can either believe the crap you did read on wikipedia or think for yourself.
Truth is America is the only place in the world where you get that engine in an S13/S14 chassis, and not the only place where Z31 NA was sold. Seeing how turbo CA/SR need frequent maintenance, they would just have massively failed in the US, which would be much worse than having more power than the bigger GT model from the same seller.


Anyway, any LSx engine is quite fun in these. There also are some fab kits to fit them quite easily.

Ive had good experience with vq thus far..

:whip:nice to see you have your head up your ass again and only believe what you think is true.

LSx engine is the only way to go. available, swap kits are done, hundreds of pictures, everybody knows about it and can help with wiring etc...

All motor performance means you lose all 4-cylinder engines as an option.

unless you feel that < 250 horsepower is considered "performance" in which case...

Anybody have any input on this type of motor??? Sounds interesting

Dam guys haha you're all making me think about going LS. Im still gunna give it some thought but as of now LS would be the best way to go for me considering my step dad built his 67 camaro rs/ss with a 406.....he might be able to help haha! Thanks for all the input, keep it coming. Also if anybody wants a steal on a Blitz Nur Spec for an S14 pm me or check out my thread in the for sale section

vg 34

You all are dumb. VH45 all day erry day

This BUT i feel if you have the money a vq is the better engine.

VG's are for poor people and people who just really like doing something with outdated technology. That's why i play with em. They have terrible harmonics. Just food for thought. It's some money to put a vg30de crank into a single cam block too. Just to take advantage of using a GOOD harmonic balancer. VG30e's are notorious for spinning bearings at higher power levels. I'm convinced the oiling system is up to par with a shimmed pump or turbo z31 pump but i went as far to have my rotating assembly fully balanced and crank micropolished/recut and STILL might fuck it all up. There's some vg30dett's making 600-700whp BOOSTED daily driven. Never once have been cracked open for "building".

If you want to enjoy your car and drive it now and keep your ka it's mad easy to just throw a t28 on it, some injectors, management and squeeze about 250ish out of it. More has been made internally stock but isn't often recommended. Dont be intimidated by turbocharging. Lots of people have have broken 5 year mark on simple ka-t setups without breaking anything.

As long as you keep this enjoyable for you it shouldn't be difficult. Dont bite off more you can chew. Stick to what you know and build onto it with things you dont and you will have way more fun. VQ and LS swaps have prefab swap kits and a host of writeups available to aid you. People can throw the originality card up all day but in the end you just can't mess with the tried and true setups that work most of the time......

If you wanted a nice NA build go with a 2JZ-GE. They are great engines and you can do alot to them before going TT

If you do go with the VQ, make sure you go with the HR version. Much better overall!
