CX-Racing Test

[nickkaplz]

OK guys i drive a 1992 240sx le. this is my first thread, and post for that matter, on zilvia. My car has been running a cxracing test pipe, catback, and radiator set up for about 6 months now without a hitch. B/c of this i have decided to run thier turbo kit and see how long my car survives without a tune like they say it should. here is a link to the kit cxracing.com: Newly Released Complete Turbo Kit for 91-94 Nissan S13 240SX with Stock KA24DE DOHC Dual Cam Engine
What i plan on doing is reviewing the arrival (packaging, quality), install, and over all quality of the kit once it is running. I know its not the best quality but thats why i bought it. i have more engines so if i blow one i blow one. I have no connections to cx racing so my opinion will be strickly based off the quality off the kit. please leave any feed back if it may help.

[rob22]

i was actually thinking about purchasing one of there kits
but ended up piecing together my own.
when are you getting the kit?

[nickkaplz]

its being shipped as we speak

[rob22]

thats cool.
how much did you pay?
whats all included?

[nickkaplz]

[Edwin562]

im looking forward on seeing your outcome.. i will subscribe

[rob22]

keep us updated!

Heh, I hear detenation on many ka's with 87, they really should run on premium as is. Throwing boost on top of that is not that great of an idea. Then your going to throw on a bigger turbo than a t25 and run it with 275cc injectors with no ecu tune.

Its kinda hard to screw up a catback and test pipe, even if it might sound bad what problem would you expect to have with it? Its not going to rust and its not going to self destruct. But your luck with their exhaust is prompting you to trust them with their turbo kit?

CXRacing is the only one offers a production Turbo kit for this car and engine.

False and they cant even grammar check their website description?

Most of the 240SX are swapped with Japanese SR20 or RB Engines, but with these engines getting harder to find and increased costs

false and false. I believe most 240sx's still have ka's in them, and they are getting harder to find and more expensive since when? When I got my first 240sx 9 years ago it was like seeing a ghost anytime you actually seen a sr or rb. They were so expensive it wasnt funny. Almost not even worth getting. I remember a local tuning shop had a rb26dett sitting in their showroom with a $10k price tag hanging on it about 10 years ago.

but no major vendor has produced such a kit. CXRacing is the 1st vendor to offer a complete kit.

once again, no

And take a look at the install picture on their site. They are not only incapable of understanding proper crank case ventilation, look how short the turbo inlet is... the maf is way too close to the turbo. And then what is this? A black plastic maf? So thats not a stock maf which means they must have tuned their own ecu.


You would be much better off starting with something like this as a base *ISIS Turbo Upgrade Package - Nissan KA24DE 91-98 [ IS-TurboKitKAT ] - Enjuku Racing - Performance Parts and High Quality Fabrication and getting your turbo lines as they dont come with it and taking their word on the fact that you will need a tune.

Take it for what its worth, but I can confidently say I have seen my fair share of built 240s and tuned several as well.

^^^^^ Brandon speaks the truth...seen it personally...

[roboticnissan]

I bought their sohc turbo kit. Everything bolted up really well, the motor lasted an hour Haha. My sohc had over 200k miles tho.

ah, nismo junky, had to look at threads you created to see how I knew you and came across your s13 fs thread.

lol, yea them "no name" coilovers on the s14 are actually really nice arnt they? I wouldnt put my rep on them if I didnt think they were good.

[lazysk8er2]

i dont care what anyone says, u need to tune the ecu

[Biggamehit]

I dont know about the full kits but I have been running a CX racing manifold on my Holset RB setup for roughly 2 years now. biggest issue I had with it was the tube design, it is not accurate at all. Two studs cant be utilized right under the turbo mounting junction and one is a super tight fit.

It has never cracked on me though but getting rid of it soon.

I also ran a CX racing Intake manifold. Pretty bad Casting job had to patch it with jb weld to stop leaks. Now I run a ISIS intake manifold.

good luck.

[nickkaplz]

I completely agree that the ecu needs a tune and i dont plan on going super hard on the engine until it does. All the things posted about the kits web page are true and im not fighting that. this is just a test to see what happens and honestly i dont expect good results, i am just willing to try and see what happens. after the initial install i will run the car for about a month before adding injectors, fuel pump, tune, z32maf, spec stage 3 clucth, flywheel, and many other pieces to max the kit out before blowing the stock internals all over the side of the road.This is simply a quality test, not me trying to tell some one to run this kit instead of another brand. Trust me i know what im getting into with this

[Biggamehit]

As stated the tune is everything...

My first KA-T setup cost me 800 dollars and was solid because I stayed below the recommended boost levels. I added a wideband, safcII, S15 injectors and backed the timing off. I drove it daily along with lots of drifting, auto-x and some drag.

Keep the boost reasonably low and you will be fine. Whats the compression of your engine currently across all 4?

[nickkaplz]

i havent had the compression checked, the engine just hit 100000 and runs like a top. i think will be getting a rs enthapy tune. what companies do you advise for this set up? and it will see 7pounds boost at max.

.

This is arriving at my doorstep today.

Ken was kick ass to deal with when ordering. I cannot wait to get it installed and get the car running.

[nickkaplz]

i considered that kit for a while, but it seemed to be missing too many things for the price when compared to the cxracing kit even though that is still a great product

[waxball88]

I'm running the cxr kit. Bought it 2 years ago and everything worked well til my engine blew. Now i'm built but with the same kit. From manifold to i/c to exhaust.


How your manifold/dp fit to the Master cyl depends on who was welding that day. I lucked out and have enough room for a heat shield. I wrapped my downpipe anyway too.
Things i'd recommend
Throw the gauges they give you away
BOV is ok, but idk how long it'll last.
Cut and modify their i/c pipe on the hotside other wise you get a cluster fuck when running a filter.
Wrap downpipe
Heatshield
DO SOMETHING WITH YOUR PCV
GET A GOOD TUNE

Things i'm running not included with kit.
Enthalpy tune
sti 550s
Wideband
z32 maf

[nickkaplz]

How long did you run your kit without adding anything new?

[Biggamehit]

Look at the kit like buying beef.... in raw form really not that tasty. You gotta add some species to make it better. Essentially you will have to pull certain parts from the kit and or add others. I am for building your own kits as you learn much more if you are lacking the knowledge. With the amount of part outs on this forum and others, you could assemble a kit for about the same or less _+ $400-600 dollars maybe.

[nickkaplz]

I would like to build my own kit one day but as of I now I have no turbo experince so this wil be a good Learning experience and base for me to add to. BTW I am looking for used sr injectors or something similiar if anyone has some for sale

[ca18_luv]

It really depends. I ran kit for a long time about a year. However i tore apart my entire ka and freshed it up. Just a stock rebuild. I had the top mount kit (not sure if you got top mount or bottom mount). Too lazy to type a paragraph so imma make it quick and if you have any questions feel free to ask

Pros
-Kit fit all really well
-Customer service great
-Packaged well
-Ran great
-Drove the car all the way from Santa Clarita to Salt Lake City, Utah for business on 12lbs with no issues
-I DD the the car at 12lbs everyday and it was sex

Personal cons
-Exhaust mani started to crack and causing leaks(had to weld supports)
-Greddy "STYLE" BOV was giving me pms issues
-Diagram on wastegate blew causing me to over boost and eff up piston #2


Things i would recommend
-Do it right and take time while putting together
-Do a stock rebuild on your ka
-Dont reuse your head bolts as they stretch, get head studs
-Dont go over 12lbs
-As stated by someone else do something with your PCV (i blocked mine off and removed butterflies from intake manifold)

A couple other things i did
-370cc injectors
-Braided lines for oil feed and return
-Head studs
-Felpro gasket
-Bigger radiator
-Got a chip i had to solder into my ecu for the tune (forget name but it made a huge difference)
-255 walboro fuel pump
-Boost, Water Temp, Oil Pressure gauges


If i remember more i will add lol




All in all i was please with it for being my first boost project and something to learn from.I loved my KA-T.

[feito]

definitely following this thread

[ca18_luv]

ill post a pic of my setup once i get home, dumb work computer wont allow me to go to photobucket -_-

[dj6923]

Good luck with the kit. I believe I've seen you on hwy 65 or 459 once or twice. I drive a purpleish rbs14. When I saw this car I didn't have a front bumper so all you saw was the I/C. Anyway it seems like you have a plan and its moving along fairly well. I also have a few Cxracing parts on my car and haven't had any complaints yet.

[thrax]

I'm sure lots of people will follow this thread as this kit is often asked about.

[nickkaplz]

this is the bottom mount kit and hopefully i will be able to answer all questions about because that the reason why i made it. a lot of people seem to want this kit its just not documented very well.

[nickkaplz]

I do now have a set of Sr injectors and a n60 maf headed my way and the turbo kit should be here on Thursday

[nickkaplz]

i feel really stupid for having to ask this, but will an ecu tuned for a t28 work with this kit?i ordered one off the rs enthapy site with a tune for my injectors, and maf, but i didnt even think about turbo size ..... i know im stupid but it was a great price. if it helps this kit will not go above 7 pounds
