To all members: This is going to be our official KA buildup car. Rob's s14.5 This is a great example of the right parts, being used correctly! All members looking to go ka-t, pay attention; This is how it should be done!

While I hope this thread's intent stays focused on Rob's build, I would like to open the option for all members to ask 'advanced' questions about how to build a KA in here, hoping that Rob will find time to answer them as well.

As always, look at the other KA sticky, and Turbo selection sticky first before asking any questions.

Again, I thank Rob for posting this, and hope this thread becomes a cornerstone of the 240sx section here at NissanClub!


I will post a full write up of this s15 conversion nasty 240sx soon. Just stopping bye!

Yet another KA build. What turbo is that? but that manifold is sex. May I know who makes that? Definitely something to keep your eyes open for.
KA = cheap/large displacement/tons of aftermarket and running 9's in the quarter with full interior. I will be pushin 10's.

Manifold is Xcessive motorsports/groundzero motorsports. Same company.

turbo is or automotosport .. Home of the worlds most HP and faste EVO i think.

They are pushing like 700whp from the KA on the same build but larger turbo and standalone.

Very nice to see someone actually building a car again. I don't see much of anything I would change on your car at all (maybe because I've got damn near the same parts hehe). Baller on the Nismo stuff too...I know how much that stuff can cost!

My only serious 'real' question, is why the choice of running 65 lb injectors? They (safely, at like 90+ duty cycle) are going to limit you in the neighborhood of around 500-530 crank HP safely....which would translate to about 460/470 whp safely... that maybe enough to just crack the 10's with Drag Radials...but why not kick it up to a gt35r and some larger injectors? Everything else is bulletproof, why not really throw some power to her??

Again, just MY opinion on that hehe...

Only possible suggestions to you (if you can even call them that lol)
- Ditch those EBC or whatever pads and get some Carbotech Panther + pads.
- Look into getting SPL Front Tension Rods....this way you can dial in some caster up front (you want +6 +7)
- Look into getting some SPL Rear Upper control arms..

Other than that, best of luck, and THANKS for posting this. I needed someone to put up a proper KA build, and this answered the call!! I'll change the title, and make ths our official KA build!
