After seeing all of the threads on the SR and KA engine im gonna save the time to dispute it and see whats yall opinions are on which path i should take my car. Im about to be 16 and have a 96 240sx. The only engine mods are gonna be headers, new carborator, intake manifold, intake, downpipe, ignition computer, spark plugs and well i guess every freaking part I see. I want to run around 400 horspower before im done with my car and thats including exterior and interior looks (seats, shifter, steeringwheel, rims, bodykit, etc.) So my question: To run that power using a Turbo that gives me around 100 should i keep the stock 240sx motor or put SR motor in. I dont think I want a KA. Please post your opinions.

#1: This is a EFI car. No carbs. #2: 400hp is impossble without forced induction (ie No2, supercharger, turbo)#3: Both motors are able to see 400hp on turbo, but neither will do it with the stock internals#4: Welcome to NICO. We know a lot around here;)

And if you want my opnion, I say go for the SR. Why you may ask? I'm a dork for stuff from Japan. The idea of a truck engine under the hood of my drfit baby is an awful thought. But I have a CA18DET. Aluminum is for cans, not engine blocks;)But seriously, the KA is a potent engine that can be a beast if built right, and a b|tch if thrown togeather. The SR is a BEEFY piece that is able to see 350 on the stock internals. Either way, get ready too spend upwards of $5k-$6k for your motor (built KA vs. SR swap done right by a shop, or $4k for a SR done by your self in the garage) BTW...Bolt-ons on the KA will see you at about 200hp at the crank.

Yea man I know my car parts even though im only 15 (16 next week) im subscibed to the mags like import tuner and superstreet. I want an engine I can pay somebody to put in and then I can start throwin on parts like air intakes, manifolds, downpipe,turbos and so on. I found a website that sells the SR engine and shows only the parts that will fit it. Its like a dream come true.

I agree about the KA engine. Who really wants a truck engine in a hardcore import. Ive never been into 240sx's lately but after seeing a decent one for sale and researching it for weeks im still a newb. Hopefully using this website I can get informed more in depth.

Thanks for your opinion now im sure ill stick with the SR motor and start throwing on parts left and right. One last question though. When and if I buy and get it installed am I going to need to do any tuning to get to to pull 400 ponies. Like you said about the KA, its either built right or the only thing guaranted is disaster.

YES, A SR will not make 400hp on stock rods, bearings, pistons, injectors, turbo etc. You might see 240hp on the stock gear, but at that point, your clutch will be toast. Also, ditch the subscriptions to those ricer mags and get one for Sport Compact Car. Dave Coleman is a GOD. Also, read this. This is what you are getting yourself into.http://www.sportcompactcarweb.....htmlhttp://www.sportcompactcarweb....lvia/

Here are the things my car allready has:Injen cold-air intake, B&M short shifter, GREDDY Cat-back exhaust, GREDDY Front Strut Bar, Stage 3 Dual Friction racing clutch, and U/O Racing Pulleys still in the box. What of that will fit on the SR engine and what other parts will I need to keep it running smoothly and to be able to hand 400+ ponies. Now I need to look for someone who can install this engine.

you do understand yore gonna be lookin at over 10g's when all is said and done on the engine alone(including electronics) probably closer to 20g's to finish the whole car.

as far as what parts will get you there search there are hundres of threads on this. you should also start lookin into learnig mechanics if you want to keep it arround the previously mentioned #

i say screw it and buy a honda, get a b16 swap, and call it a day

Look, whatever crap you've been fed about the KA (or will be fed... since I doubt you've heard MUCH...) is totally subjective. Whatever you have planned for you car will take a LOT of work, boosting the KA or swapping an SR, RB, CA, whatever.

Also, may I suggest that you set some realistic goals? The 240sx is a pretty light car (even those s14s... he he he.) 400 hp is WAY over the top. Search around and you'll find some real helpful information.

Anyway, good luck with everything and welcome to NICO.

Everytime I start a project car, I just boot up my ps2, put my NFSU disc in. Then I start a new game, and chose the car that Im gonna do a project on. I play through the game using this car, and follow the same steps in real life. If you dont see the car you want to make a project out of in NFSU, dont sweat it, this is just informing you that the car you had plans for is vastly inferior to the likes of the ford focus and honda civic that you DO find in the game.

Oh, and dont forget to get neons under your car, its not fast if there are no neons.

How hard do you want to squeeze? I/H/E/C and ECU upgrade will net you around 165 HP at the wheels. Give or take. If you get forged internals, raise the compression, and alter the timing, you MIGHT get 190 running race gas. Check out the KA forums. Those guys have been working at the N/A KA for a long time.

well the more people talk the more i realize what my overall question is... in my mind im debating these things:

1) Keep the KA engine and ask YOU this question...What parts will I need before I can start boosting and throwing on other parts.

2) Sell my KA and buy an SR engine and ask YOU what parts im going to need to start off with before I can start putting on other parts.

Yes im too confused...which way did yall go and would you stay that way or do it over the other way? Which way is cheapest because my budget is about 200 to 700 a month on spending money? How easy is it to buy an SR engine and get it installed and install the necessarys and how much will I need to start saving up for? Last, which parts will I need to upgrade on the KA before I can put parts on without worrying about it blowing(Its got either 66 or 77 thousand miles on it, somewhere between those, it doesnt exceed 80 thousand.)

umm.. its called making a decision yourself, or better yet letting NFSU make it for you. But seriosly.. use yer own brain, thats why you have it after all.

I want to go to WYO Tech so I can understand what yall say most of the time, being 15 and going on 16 its hard to be serious in the import scence because most of the kids my age want ps2's and body kits and sparco seats and chrome rime...I think they are stupid because they dont know how deep imports go...This motor talk excites me but most of the time I couldnt tell you what you said if you asked me 3 minutes after you said it...lol but im learning dont hate

Honestly, the best thing to do when you are your age is to get a car that is as stock as absolutely possible and that you dont care about all that much...because that car WILL end up getting wrecked, or mechanically wrecked within the first year or so of ownership. I only say this out of experience, when I was 16 I loved cars as much as I do now, but I was a bonehead with mine and managed to mechanically destroy that poor little car with my attempts to go faster, show off, and be cool. I'm not saying dont get a 240 or anything, becuase they are good little cars albeit a little tail happy. BUT, just make sure that you can deal with its loss in the future and I think waiting a while to reallllllly make it fast is a very good thing.

Maybe I should put my Sparco seats, steering wheel, shifter, pedals, carbon fiber dash, jdm floor mats, and blah blah everything else I can afford on the interior, then throw on my body kit, paint it, put some volks on, maybe a small turbo, keep the intake, change the intake manifold, put a strut tower bar, change my suspension, tires, headers, downpip, keep the greedy cat back exhaust, put a huge system in and try to get a couple of asian girlfriends...I guess I should wait until im older and know what im doing before I try to make it fast. ill learn now instead of wrecking now, thanks mate

Yeah, or like I said...mechanically wrecking. I didn't so much wreck my first car on the outside, it was all on the inside ;) It was also 99% because of my desire to make it faster without knowing nearly enough about what I was doing. Just try to enjoy the car for a while before you get too crazy with it, you'll have plenty of fun anyways...trust me.

I dunno where you get your info, but the SR has gotten 550rwhp on stock internals (pistons, rings, rods, bearings, crank etc) The turbo is what you call an accesory, not part of the internal workings of a block.

get a cheap manifold, a used small turbo, piping and a FMU. You'll only get around 190-200 whp but it will be cheap and your car will be faster than the majority of whats on the road.

Really i would suggest just keep it stock until and upgrade as nessecary.
