PhatKA-T.com Stock S13 KA-T goes 11.7 @ 118mph

[IvanAtSPRacing]

I took the PK R&D car out to the track this past Sunday and made two all out passes.

14psi 12.0 @ 11516psi 11.717 @ 118.54 mph

car is a 91 240sx with 115,500 miles. Stock long block. PK turbo kit, PK fuel system, PK intecooler, AEM EMS

This car has full interior, working AC, radio, power windows, etc. We did take the spare tire and jack out of the car tho.

The car was run on a 24.5 - 8 - 15 MT ET drag tire

Sorry for the poor quality and the damn rotory in the background making all the noise.

WOW! I don't know what else to say. Awesome runs.

[andrave]

great! sweet, wish my car was that fast. or that running. what kind of lsd are you running?

[IvanAtSPRacing]

Nissan VSLD

[Structure240sx]

were you using the traction control function of the ems? 1.7 60's is great, i know you had drag tires on it but still

Nope. I havent even tried the traction control on the 50+ Supras we have installed the AEM EMS. I guess maybe some day I should see how it works.

I wasnt using the two step function to launch or the anti lag either. Just driving the car. AEM EMS is bad *** but I am not exploring the frills end of it yet.

I did play with the two step and the anti lag at the shop tho. At 4000 rpms, on the two step, the turbo made about 2psi boost. With anti lag turned on, at 4000rpms, the turbo made 15psi with the WG fully open. Its pretty sick.

I think the 1.7 60ft was OK... I KNOW the car has WAY better 60fts in it. I just didnt want to risk breaking anything.

[WDRacing]

16 psi and in the 11's. Thats a really good bench mark. The AEM EMS is simply an awsome standalone. I'm excited about trying it out myself.

WD

[IvanAtSPRacing]

Thanx WD.

The AEM rocks. I cant say enough good things about it. We will have our first production EMS units for the 240 next week. Ryan is getting all the info and pricing on the web page within the next 24 hours. First ones availble are the 1600, 1600U, 1601, and 1601U. These cover the 89 to 94 240sx and most of the other 4cyl Nissans of that era. The 1600s are for the USDM cars and the 1601s are for JDM cars or USDM cars running the SR motor and wire harness. I believe the Skyline will be next out, and then the S14 is right after that.

This winter, I will probably have H&Ks car at the shop to play around with while I put some stronger pistons in their spare motor. I am planning on really exploiting the potential of the AEM on the dyno and will probably work on intake manifold design at that time. How about a nice large plenum short runner intake with 3" throttle body with IAC built into it? I wonder what the weight savings would be just getting rid of that HUGE KA intake?

[WDRacing]

Yeah, I'm gonna build a custom intake eventually as well. The Long skinny no flowing torque monster KA intake is horrible. Somthing along the lines of the Veilside GTR intake mani with a Q45 TB. I'm just gonna install a secondary IAC.

Dude...The S14 after the SKyline? You SUCK!!!!

[xxtrizz]

hey ivan that brings up a good question is your email functional yet? HAHA I havent tried it but I figure it would be better ot ask you here.

[klattr1]

what a monster.aftermarket intake manifold would be sweet, especially made by you.

We build an intake simular to the Veilside intake for the MKIV Supra. Testing has been done on the Veilside and the velocity stacks inside the manifold actually hurt performance, so we dont have the stacks. I would love to design a mani that would work for everybody but all the IAC stuff and TB with like TPS signal would compromise the construction (IMO). Check out the one we make for the Supra.

[WDRacing]

Yeah, that manifold pretty much makes me horny...nuff said about that.

I was looking at a very similer design. Also with no internal velocity stacks. I believe thats more of a NA performance problem. Chances are if your buying or building an intake like that, your turbo is putting out enough volume to make up for any loss in velocity with the short fat runners. Being able to take advantage of a full 3" intake setup from compressor outlet to TB would improve flow so much its silly. The KA is such an untapped resource.

You guys having to fab up manifolds for mass production does tend to suckass. Building one for me alone is WAY easier. The problem I was looking at is the transition from runner to flange to head. I suppose I could seriously port out the head to make things alot easier, but I don't totally want to ruin the off boost driving. I dunno...I can't seem to make up my mind and simply go all out drag or maintain some streetability.

Either way, you guys still need to get the S14 AEM EMS out. Then send me the maps after you've tuned one...lol.

[SloS13]

Not bad for a 'truck' engine

[WDRacing]

I smacked one my Airman just last week for saying that. He was giving me the whole, SR's are Better speech. Him and his infinite wisdom of 19 years.

[SloS13]

I hope you know I was just kidding. Im a strong supporter of the KA and agree fully with your comment about it being an untapped resource.

When people ask how much boost one of these will take, the answer is 'i dunno, i dont think anybody really does' but it looks like we're getting closer to an answer here

Honestly, its not how much boost it can take, its how much HP it can make. I can pretty much assure you that making 400whp WILL kill the motor fairly quickly. I have a car here that I have been experimenting with. At the 400whp level, the ring lands are collapsing and compression is lost in that cylinder. continuing to operate the car at this level starts to break down the piston more and more until there is a hole thru the piston.

I know I could make 500WHP or more ONCE. Unfortunatly, the stock KA pistons just cant handle the power for long.

[574-240sx]

Dam thats pretty quick. I may keep the KAT or buy a SC300 and sell the 240. With more parts being manufactured for the KA, I might keep the 240.

I knew you were joking...

[ultimatuc]

wow. I'm getting very impatient waiting for the ems.

[fiznat]

Damn Ivan I wish you guys were closer to me so I'd have someone around to help me tune this thing once I get it together... I swear hardly anybody even knows what the AEM EMS is on the east coast, nevermind being good at tuning with it.

Sweet work with that KA though like I said before, I'd like to do pretty much exactly the same thing, except without all that ring land cracking engine loosing compression dealey youve got there...

[Drift Machine]

Those are some sweet times.

Damn't this is really making me want to get the AEM EMS next summer really bad....even though I told myself no more money into the 240

[Altiman94]

I just came into a free ka24de, so my 89 is going to be de swapped. A few parts have been ordered for the turbo kit as well. I'm hoping to make around 250-280 rwhp.

[f1seb]

What kind of clutch is in that car Ivan?

[IvanAtSPRacing]

Its an ACT Max series pressure plate with street disk (fiber) and a resurfaced factory flywheel.

[goldenchild]

WD are you in the Air Force

[WDRacing]

Yep, USAF Combat Rescue...

[kamele]

can you give me the details of the turbo kit you used?

[IvanAtSPRacing]

I built the kit at my shop (Sound Performance) after doing a few KA-T turbo kits. The kits I had installed before were not designed or constructed well which inspired me to build my own. I am lucky enough to have customers (Heath and Keith) who are twins and own a 91 240 who agreed to let me guinne pig their car with a kit. It took a couple months but I believe that I built the most complete best kit for a KA. The power numbers speak for themselves. We have barely breathed thru this motor and its already making more power then everybody for the boost level.

The only hold back at this point is the fact that the stock pistons keep cracking ring lands at about the 400 whp level. I have put two motors in H&Ks car now (both stock) and the result is cracked pistons. I have a new motor going together with forged pistons so we can turn the boost up and make some REAL power. I am shooting for 500 whp and want to run a 10.xx ET with their car.

All info on the kit can be found at http://www.phatka-t.com

If you have specific questions reguarding the kit, feel free to email me, call me at the shop, or post up a question.

[xxtrizz]

Hey Ivan im curious are you guys ever gonna build up a manifold for the SOHC of the KA? Im working on turboing my car you guys are pretty close to me compared to other shops and if that is a future addition then I would most likely seek you out.
