KA-T Build This Summer

Post by pballa88 »

*Can't post in KA-T Basic's like I wanted to yet I assume because not enough posts since I just like to read, but anyways onto my hopeful build. Suggestions please!

My background: I am 20 years old going to college and working I don't know much about cars at all, but really wanting to learn even though I don't really have any friends that are into cars. So if your local and need a hand with something I'd love to learn.

I plan on purchasing just the KA24DE block to take it all apart and put everything back on basically learning everything I can by "rebuilding it" I hope to buy a block for about $200-$400 not really worried about miles.I plan to not purchase a 240sx shell until I learn almost everything I can about rebuilding the block.
My budget would have to be $4000 on the block and $2000 for the shell and transmission.

I would also like it to become a drift car.
Mods I'd plan hope to have to make 350whp:

Haha I had a feeling someone would post that.
By the way is Retard Timing mandatory for any KA-T build? A little confused on it, but I'll have to read more thoroughly on it.

Pretty much yes, regarding the timing helps prevent detonation, which will save your piston from getting fried. With boost most use a ratio of 1 degree per 1lb of boost. From what most say that is pretty conservative.

If im wrong someone will correct me.

i have to same setup as you do minus the rod and piston i was broke in the build and went with oem piston and stock rod, but 6k miles later and a few beatings still running great,

take a look at hx35 thats what ill be doing soon there cheap and everywhere locally. Dont forget your clutch, look at white bunny clutch theres two options d12 nissan flywheel set up or rb20 flywheel both are 240mm surface area unlike the ka where its only 225mm.

and rebuilding isnt hard as it sounds just take you time and check everything you do twice or 5 times like I did took me a month to finish my engine, i wrote down all specs that i needed from fms so there right next to me.

good luck man i enjoyed building mine and i would do it again, theres nothing like opening ur hood and knowing you built it,

If you are not tuned (not recommended), I would retard timing by 5* at the dizzy (15*). If you have a tuned ecu, leave the timing at 20* (stock timing), and the tune will automatically retard timing when it is necessary.

Oh sweet how much horsepower are you pushing and how much did it cost for your build?
Yeah I'll have to learn how to drop the tranny and replace the clutch... seems like a bi*ch. But if you own a 240sx you must know haha.
Thank you for the encouragement man, really can't wait for this ,but I need to do more reading hah.

Wow, there are still people here! I thought the forum died a few months ago lol. I was curious if anyone has tried the .63 ar turb housing for the hx35 from Tim's Turbos? I read on other forums that the clearances are too big to make boost, but I wasn't sure if that was true or not.

Kind of a basic question, but does anyone recommend any specific tools or tool package I should get to tear apart the whole block?

just basic hand tools mainly 10/12/14mm a 12mm 12 point for your ARP bolts.

my hp i dont kno what im running never dynoed it, i have raced a 350z and g35coupe and i can creep away from them with a slipping clutch. or they cant drive.

my clutch i hate going under so i just pull the whole motor out and change it. this gives me a chance to clean it up and find leaks or issues need fixing its a win win for me to there to much time

Okay I figured I would just need pretty basic tools.

haha either way its always better winning with a wayy cheaper car then more expensive.

Yeah, after I posted that I was just like I'm going to buy the block first anyways so should be easy to install really.

just make sure motor is good. i bought my first motor to find it had no rod bearing on cylinder 3, it was in the oil pan. the crank was so out of specs i had to buy another motor as crank wasnt for sale locally

Yup a little worried about that since it seems that most motors are just out in the open to be beaten on by the sun/rain etc... Hoping to get one from my mechanic that only works on sr20's so he should have a ka24de that'll be swapped out of a 240. Just the matter of patients. Hopefully it comes with a wire harness as well..

Download yourself the FSM for your car here http://forums.nicoclub.com/240sx-fsm-fu ... 11075.html
It's a nice thing to have access to. Check out all the stickies here too. Airman has a good one for getting your fuel pump for cheap, and there's a couple other good ones in the tech section. Zilvia has a very active for sale section. Also, not sure if you know, but some people use a 248 exhaust cam set 4 teeth CCW to have 248/248 cams. Nice and cheap upgrade to consider. Sounds like you have a good start with what you've listed. Good luck!

I looked into the FSM's as well might just buy the book. I'd rather read off a book then a printed paper or computer. Yeah I am surprised how cheap I can find BNIB forged internals there.
Cams was another thing to add to a strong engine perfect thank you for sharing!

550cc's will get you to 300 maybe 350 but if they do (correct me if I'm wrong) you would be somewhat close to maxing out the duty cycle on them. I'd go with some 740's or hell even 1000's in case you want some more room to grow :twisted:

I have been busy lately, lagging on this thread.
Anyways I have been looking at turbo kits and non turbo kits, just the basic parts by themselves, and its hard to see whats the cheapest, because of course I am on a budget with this build. Not only I am looking for a good price but also quality. For example: These are the turbo kits I am looking at:

T04E Kit: http://www.cxracing.com/mm5/merchant.mv ... A24DE-T04E

ISIS RS3871 Kit: http://www.enjukuracing.com/products/*I ... 52d98.html

T3/T4 Kit (looks too cheap to be true): http://www.fmpracing.com/Turbo-Kits/c53 ... 0f303f1716

Any advice on turbo's, kits, or buying things piece by piece would definitely help.

I also understand Turbo's are basically the last thing I want to purchase before rebuilding the KA24DE with forged internals, making sure I have a good fuel system, and the most important thing a tune (after the turbo is installed).

i had the cx racing kit the older one. the turbo seal went out on me 1k miles and rebuild it with staggered oil seal and new bearing. Then that went out the shaft was being eaten up at 3k.miles later.

knock off turbo are ok for short term use. im saving for a holset hx/hy35.

I say got for the cxkit on ebay its like 100 cheaper for the same kit for some reason then there store.

the bov leaked i couldnt get it to open right so i resealed it with rtv and now works great.
there Wg no issue yet and im at about 7k miles on the kit. I had there older kit with there center mount manifold, there new one look promising it pulls turbo forward more and lower too. my darn center mount one almost melted my brake master res and caught on fire while drifting.

personally i would go for cx kit with there Ic kit and swap turbo for a name brand. there kit fits great tho.

I was almost tempted to pick up a prepackaged turbo kit a while back, but came to the realization that I could piece together a higher quality kit, and pay either the same or just slightly more than those kits. I put together a complete turbo kit for about $2000 with quality parts. This is including all the things your kits are missing such as injectors, MAF, tune, gauges, exhaust etc. The majority of my parts are second hand, but if you do a lot of research and check the parts thoroughly before purchasing you should be ok with used parts.

A couple of suggestions
1. Buy the manifold and the down pipe from the same company, this way you know they will bolt up without major clearance issues.
2. If you go used, you could pick up most parts online. Unless you are buying the turbo brand new, or from someone you trust, I would suggest waiting to find one locally so you could check all the specs and feel for shaft play in person.
3. The tune is super important, but i noticed you are going with Enthalpy. Great choice. His customer service is amazing.
4. If you piece together the kit, i would suggest creating an excel sheet of all the parts you will need, with estimates on what you expect to pay. Keep the sheet up to date whenever you make purchases or need to add items. This will help you stay on budget.

As far as those turbo kits
1. The T04E turbo in the CXRacing kit may be a bit laggy for drifting. If your power goal is less than 400hp I would suggest a t3/t4 or hx/hy. You can get decent spool and still meet your power goals.

2. The ISIS kit runs a bottom mount mani. I'm not completely sure, but that manifold and turbo are probably t2 flanged. If this is the case, you may need to redo your setup if you ever want to go bigger. The way i see it, if you go t3 top mount you have a ton of options. If you want super quick spool you can go with a straight t3 turbo. If you want a lot of power, there are a ton of big boy t3 flanged turbos. There are obviously tradeoffs between quick spool with weak top end, or lag with awesome top end power. Your choice of turbo depends on your goals.

3. The turbo in the third kit seems like a decent size. Its approximately a 46 trim turbo which should be good for about 400hp. The FMIC is going to be a PITA to work with. Its just a universal kit, so you will need to cut and weld every piece of the piping. If have to pay someone to do your welding, this will eat up all of your savings. You may also need to make a custom downpipe, but i think I've seen some members using this manifold, so they may know of a downpipe that bolts up to it without clearance issues.

To recap, if you have the time and patience to slowly collect parts i would suggest piecing together a kit. Alot of these turbo kits are low quality, and you may end up having to redo a ton of stuff to make a reliable final product.

Sorry for the long post but i hope it helps. LOL

Awesome thanks for the information guys.
I was thinking about purchasing the manifold and exhaust system used since there can't be too much problems that can occur correct? I don't hear much about manifolds cracking or exhaust problems.
Leaning more towards purchasing things separate at the moment, seems more reliable and it can even be less expensive then a kit. I was even thinking to go less HP do to the fact that this will be my first drift car and I understand things will go wrong and I should probably go with a less expesensive project first to learn more.

Don't think less expensive, research what you want to do then set out to find your parts. When you decide to go cheap because this is your first time around, you end up buying.g parts of lesser quality. If you plan accordingly this could be your first time and it could be a very successful time.

I updated my build I have been making a somewhat of a spreadsheet but on Microsoft word and I came up with all these goodies.

Let me know what you guys think of my new updated list for my build. Thank you for your time.
