  1. if i had a 280zx 3.9 diff, and say a r200 vlsd short nose diff from a 300zx or q45; can i swap the vlsd section into the long nose somehow? can i still use the stock 4 bolt 280zx output shafts?

     

    has anyone done this before?

     

    What im trying to do for my 240z is end up with a drivetrain that will handle 300-400hp with easily obtained parts from the junkyard!

    any ideas?

     

    i don't have much money to work with! thanks!

  2. I'm curious. How do you stop the KAET lash adjusters(can't really call them lifters) from rattling like crazy every time you rev it at all? Mine ran ok but the rattling drove me crazy and once I had an SR, I never looked back.

     

     

    doesn't the sr have those lifters? I think of an sr, as a destroked ka24e with 1 extra exhaust valve, with weaker aluminum block. ok im just pushing buttons.

  3. I've had an L28 with anywhere from 275 to 350hp, depending on the boost level in my 73 240ZT since 1987. not a whimper on it, and well over 40K+ of HARD miles.

     

    People who go for a ride with me in it comment that driving like me in that car is like most people's idea of throttle application at an Autocross. The chassis flexed coming off a corner one day, and cracked my windshield.

     

    The L-Engine is reliable at the power level to 100K miles easily I would suspect...if not twice that.

     

    Now, at 400HP, I think you decrease reliability accordingly using the stock components. Mine has stock pistons in it, no problem thusfar.

     

    But much above this point, I'd likely go with something heavier in the piston department which I would forecast to withstand 500 hp levels in a turbo application the way I drive for 100K miles.

     

    That's damn reliable in my book. And curiously, coincides with what Bernard has experienced.

     

    People discount the L-Engine. It's a mistake. It's just most people go about modifying it in such a hamfisted way that they screw it up along the way and blame the engine and not themselves. It's not the engine's design problem if someone tuning it is an idiot. But it plays out that way because the engine never gets to tell it's side of the story.

     

    I agree! well, its good to hear the stock bottem end on the l28 is strong! Tuning is the key to success! Looks like i'm gonna look forward to plopping one in my z. BTW, anyone have one for sale in SD? pm me! haha

  4. or like previously posted an l28et would be the most cost effective, strongest, easiest motor to swap. it will hold up to MUCH higher power levels with stock engine components than any sr or ka and last twice as long. may not be as "cool" but who cares when youre shittin on ricky ricer in his sr swapped sx for a 1/4 of what he paid for his "silvia" conversion.

     

    I would like to know what power levels the l28 will hold up to.

    I know the ka will hold up to 400ish hp.

    and I've had my ka24de at 320hp daily driver for 2 years. 20k miles... still 175psi compression at 180k miles on block.:icon44: those ka24de motors are strong( talking about the japan built ones that come in the 240sx). they have oil sprayers, and block girdles. i haven;t seen that on any L-series...

    I'm interested cause i am planning on a l28 swap in the future for 240z!:mrgreen: I know someone here is getting 321hp and has over 250k miles on the stock l28!!!

  5. You want some 1.5" x 2.5" tubing about 1/8th" think, about 2.5 feet (maybe 3 feet long. You want to make a new cross member with this.

     

    The length of the lower frame rails across is 25". I think you can scavenge the old mounts off of the original x member and use those, but if you need to make you own, the mount bolt holes are about 10mm wide.

     

    I would be building mine right now, but my dad is borrowing my engine hoist right now :(

     

    I'll post pics in my build thread, when I can get started on it.

     

    Wow thanks for the info! will i need to make a "u" shape or does the engine fit with a strait accross cross member. and the tubing, you are talking about a rectangle shape, or oval shape? I am definitly looking forward to seeing your progress!!!

     

    Does anyone have pictures of their tranny and engine mounts in the car from several different angles?:mrgreen:

     

    that threaded mount thing is baddass! That tecnique will come in handy!

     

    Thanks for all the help! This is encouraging! I was getting bummed cause i couldn't find much info on how to make my own engine crossmeber and mounts! thanks!

  6. I'm just wondering if anyone has done this. I am planning on doing a ka24de or sr20det swap into my 72 z. and i want to do it myself cause i love to make my own parts and setups. I have a welder and some steel plates. What is the proper way to do this? How do i mock up the positions?! anyone have detailed pics that are up close? What kind of engine mounts can i use? and what kind of steel should i use?

     

    I searched for hours, and didn't come up with acual dimensions, or "you do it this way" first hand, factual info that i need. Although i did see a few threads, with pics, but nothing i can really use to start fabbing my own.

    I would buy a cradle/mount from the two leading companies that are referanced here, but this time i'm planning on doing this myself. Don't try to talk me out of it:icon44:!!!

     

    as soon as i can do this succesfully i will have to find info on how to wire it up and stuff. but for now, i just need to get it installed.

     

    THANK YOU!!!!

  7. why would you want 2 less cylinders and .8 less cubic inches? if the l28 has 8.5 to 1 compression you can turbo it and with injectors a z32 maf and modify a stock ecu www.e-mance.com it can be done. but its better just to get a turbo l28 and drop it in.

     

    i dunno man, sr20's are small and annoying. a big inline 6 is rad and sounds cool. and you can bolt on parts, and find parts easy.

     

     

    haha, ya i said .8 cubic inches. i must have been cracking smoke. lol!

  8. By "equal mods" I assume you mean running a stock SR against a KA after you replace the pistons because of the tiny ring lands and after you add a turbo manifold and a turbo and jury rig a way to oil it and cool it and return the oil to the pan and after you throw away the ecu and mass air and buy new ones and get it tuned and after you buy a front mount and all the plumbing needed to make it all work. Is that the "equal mods" you are referring too? How much is a stand alone now a days anyway, 1500.00? Turbo, 1200.00? Oops, just payed for an SR that's revs like mad, makes 240ish HP and almost as much torque with NO mods, makes boost at 2200rpm, comes as a complete unit that makes it a bolt in, in one day if you've done it before,(in an SX) has readily available parts and can run forever if you only be reasonable with it.

     

    I'm just pulling your strings. I like both engines but an SR is way easier and man they run well. The revs are right there. It has plenty of torque unless you want it in a 2.5 ton something. I built a turbo KA first. It ran well but then I put an SR in a different car and it was night and day. I sold the KA and have been running an SR since. I autox it heavily at 3 clubs, put on 3 sets of race tires this year, race against cars with twice the power and always do well. The car and engine are never an issue. New vettes overheat and the SR just purrs. I never even open the hood at autox. We even double drive many times with no heating or anything else issues. It's amazing to me how I am classed as one of the "power" cars. People think I have 400 WHP and I normally run less than half that. At autox with 275 tires, I normally can't run more than 10lbs or the power is just too hard to control. It is a 2500 lb car. We set the boost gain at 5% to slow down the boost or turn the controller off. Didn't mean to go on this long but I grew up with big blocks when boosting cars didn't have anything to do with turbos. I've had many very hot cars but I still can't believe what a 2L can do. LOGR

     

     

    Ya, i know you're pulling my strings..

    BTW, the stock mass air flow sensor from a single cam ka24e is the same one used with the sr turbo engines. also... the stock ka ecu is not thrown away. if anyone has one that they want to throw away i will pay it to be shipped to me! install a daughter board and you can tune it to use anything you want! only a fool would buy stand alone when this can be had at under $300(if i had somone else do it). BTW, ! paid less than $100 to oil my turbo with ss feed line, and welded a return bung on my pan with silicone drain back tube. The stock t25 turbo that comes stock for the sr motor is way too small and chokes the KA, so a larger turbo is needed. A turbo that flows enough to make well over 500hp $400... a fully rebuilt holset hy35w with 10cm exhaust housing. spools at 2,500rpm. and hits hard! or a custom built t3/t4 garrett with 360 degree bearings from a turbo shop for under $600. Plumbing for front mount... Less than $200. and a cheap FMIC... a walbro fuel pump injectors...

    basicly for around $1500 give or take depending on what you go with...

    I have a setup that cost me this much. I'm making over 320hp with a stock block with 180k miles. and daily driving it for 2 years and autocrossing and drag racing. its got over 50 passes and 5 autox races with this setup on a stock ka. I guess the SR can "Rev like mad" but i prefer making more power than an sr with a ka.

     

    if you don't do it right, it won;t work. stick to sr's cause they are bolt on turbo. don't ghetto rig any ka's anymore please.

     

    install of the KA approved turbo back in the day. I haven't been beat by a sr with bolt ons' and no-one wants to race me with their sr. even tho it redlines a couple hundred rpm's higher, and i spent less money. i wonder why? Please visit KA-t.org educate yourself about ka-t power. not a throw away motor! go ahead and call it a "Truck motor", I know i used to! I used to make fun of them truck ka motors.

  9. Gotta ask, Why are they annoying? Because they make so much power so easily, because they get so much mileage, because they are so reliable or _____________?

     

     

    they are annoying cause most peeps are pulling out the ka's to install a smaller engine that costs a lot more, and call the ka a "truck" motor. well i take the truck motor, mount a truck turbo from a cummins, and tune it, then destry the sr guy with his old crappy motor.:) BTW a ka will make more power than an sr with equal mods. how much tq./hp does an sr make if you take away the small turbo?

     

    i dunno, i just see too many f&f crowd peepz ask me if my car has a sr. i say no. then they go,"oh" and leave in dissapointment. hahaha!:icon44:

  10. Well they are both good engines. Nissan did use the SR in other cars heavier than the Sentra. They were produced for differnt applications. The KA is a torque engine, hence trucks. It makes good torque but doesnt have the higher rpm rush the SR does. In a car that light anything would get it to go! A stock KA is cheap. If you want uncommon go with a CA engine. Big in Japan but not here. What about an L20B from a 200sx?

     

     

    have you ridden in a ka-t with a larger turbo (that suits the bigger displacement, not a tiny t28)? they rev to 7k rpms and with a good tune and a cam swap it revs higher than a sr. and safely, it has better valve train.

  11. ka24de with a custom tuned ecu from e-mance.com will get you 300-350 hp from a stock block, 400 with e85. and a t3/t4 turbo. just need injectors/wg/re-curculation valve/walbero pump/intecooler etc....

     

    or build a ka block, get over 700 hp. some 1200hp examples exist but are not practical for street. 500-700 is the most i would go for street.

     

    my best friend has a s14 with a ka24de and has never been beat by a sr20 swapped car. why? because sr's are ghey and small and aluminum and have a horrible valve train. thats my opinion. so many s13/14 guys are swapping in sr20's, its funny, kinda like having a ss Chevy with a 350 and swapping in a smaller engine.

     

    i have a ka24de turboed with a holset. its pushing 320hp ish, at 14-15 psi. and i daily drive it for 2 years. the motor has 180k on it. and has 175psi accross the board. its all in the tune!!! thats the secret! get a tuned ecu and save yourself a headache, you don't need a fpr or fmu to get it dialed in. any setup is possible with stock ecu, just send it in to get chipped for anything you want.

     

    the stock tranny for the ka24de is the same for all the years of the 240sx. they are pretty strong, basicly the same as a rb20. they can handle 300ish hp for a long time. but you can get a kit to install a z32 tt tranny and use an rb flywheel and 350z clutch. that will handle 500 or more hp. go to ka-t.org
