KA24DE questions

iVteC_PoWeR · #1 04-25-2005, 03:51 PM

I'm a newb and want to know if is possible to find a KA24DE motor that has low miles because I want to turbocharge one. If not what parts would I need to rebuild to boost safely? I want a 240SX coupe(S13), but if I have to I will get the S14. thx any help appreciated.

good 7th post, newb. www.renewedimport.com sells low mileage ka's our of calgary, alberta, canada for pretty cheap. if you're looking to turbo, you could buy one of those and work on it yourself

OR

www.boostdesigns.com has a block they're selling for $2000 which includes an exhaust manifold and downpipe

your best bet is to read up on turbos too
http://www.automotiveforums.com/vbul...d.php?t=201348
thats a great thread to learn on

also, do a search of automotiveforums.com for ka24det, ka24de turbo, ka24de-t, ka-t or any other combo you can think of to find the ka-t threads. there's a ton of them

you can also pm nissanfanatic, tatII or tims240 since they're boosting (tim's almost there) ka24de's

good luck with it

actually i heard the ka24e was better for boost because of its lower compression.
the s13 (89-90)comes with the ka24e, the s14 (91-up) comes with the ka24de. btw, the s14 came coupe and fast back up till 93. read up on your facts, you know a little, but not enough to even consider turboing a car.

you must've had a typo becasue S13's came coupe and hatchback until 95. 94 is in japan. the 94 models we have here are the S13 convertables. they only comp automatic and should be kept away like the plague. there are some powerful single camed KA's, but there just isn't enough support for them. nobody makes a turbo manifold for them, so it needs to be customed. also the are usually in the 200K mile range since they're like 16 years old. not to mention that they only have 3 valves per head.

ur right. i was mistakin. its been a while since ive been here. but yeah, the s13 is 89-93 right? with the vert in 94 and i believe the end of 93 as well. then the s14, only coupe was 95-98. for some reason i was going by engine, with the new DE in 91 i thought s13-ka24E, and the s14-ka24DE. just a little mix up is all. thanks tat for correcting me.

both engines have their pros and cons but i'd rather have the dual overhead cam.. personal preference.
also, the ka24de is easier to find than a good ka24e

add: the cams in the 91-93 ka24de engines are also more popular but i don't totally understand the duration numbers.. someone else can explain that

convertable is also 93

If your compression numbers (well your engines) are good then you can turbo your current engine. You will need: Turbo Manifold, Downpipe, Turbo, BOV, Wastegate (if turbo does not have an internal one on it), Piping, Intercooler (very recomended, but not needed for low boost), Fuel Management, Fuel Pump (for higher boost), Fuel Injectors (for higher boost), Piping, Gaskets and possible any other hardware. Or you could just get a kit if you want to, such as greddy which comes with almost everything I listed above. If you search you will find A LOT of info. Also check www.ka-t.org, good KA24DE-T forums.

Actually there is a guy on www.ka-t.org that makes a good manifold for the KA24E. His SN is Jordan Gladman. From pics, I'd buy it no prob. Search on E-bay as he sells a lot of stuff on there.

Your fuel pump should be upgraded before the engine sees any boost. If I were to start over, I'd prolly buy a fuel pump before anything.

www.pdm-racing.com can explain the cams very well.

www.renewedimport.com can sell you everything you need for th de but i have no clue about the e. i don't think they make them anymore, not even in japan. if you can find a good ka24e then do it for sure

iVteC_PoWeR · #11 04-25-2005, 06:42 PM

oh yea and another question. Around what time should i be running (1/4 mile) with just a fuel pump and a turbo(8 lbs of boost) in the KA24DE?

TatII · #12 04-25-2005, 08:14 PM

with good driver, proper fuel, intercooled, you should be in the high 13's. with a S13 running a T4 turbo.

iVteC_PoWeR · #13 04-26-2005, 04:58 PM

oh yea and another thing i would REALLY like to clear up. I always hear that SR20DET is better than KA24DE-T for road races. Wouldn't stopping at a red light and taking off from there be very similar to drag racing(actually it would be drag racing right? just not at the track)? But I really dont know why a SR20 iz better than KA-T at road racing.

zdude · #14 04-26-2005, 05:40 PM

ka-t has more torque. the sr is a high revving motor so it has better drifting capabilities because you need high rpms. the ka-t is fast off the line but doesnt have nearly any revving capabilities. the sr is better if you are doing twisties or a road course.

iVteC_PoWeR · #15 04-26-2005, 08:22 PM

so basically the KA24DE has a shorter power band so it's not good for drifting. doesn't matter because im not really interested in drifting because i don't feel like crashing my car. So to sum it up SR20 is better than KA-T in turning and handling and the KA-T is better for going straight?
