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

In for any potential SOHC setups

sorry, but not at this time.

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.

So this being said, if the kA engine was to be built with stronger internals, it is capable of making and holding 450-550 hp and producing huge torque, this of course withe the proper fuel, turbo and tuning. Right?

Yes, this will be the case. Stay tuned. That exact thing will be happening soon. The S13 now has forged pistons and worked over stock rods in it now. Today on the dyno, it made 300whp at 9.5 psi. The motor is just getting worked in.

Thanks Ivan, as you saw on my other post (the one that's closed now), I'm researching everything I can before I start my buildup. I'm considering the idea of a KA engine because I've seen it produces a great amount of torque along with impressive hp numbers. I'd like to see more about your project.

Thanks again for your response.

There is a bit of info on the web site. We just uploaded a new vid last night of the new forged piston motor making 300whp @ 9.5 psi. We will be hitting the dyno hard tomorrow and again next week testing the new turbo and intake manifold. Stay tuned, there will surely be some pretty good news.

Lord, 300 whp @ 9.5 psi with lower compression pistons...that AEM EMS is a dream!

I'd be lucky if I were making 60 less whp at the same psi with stock compression pistons....

I guess the $1600 for the AEM unit really is worth it!

Keep us updated...

Dyno time and a fully adjustable standalone like the EMS just can't be beat.

Wait till he leans out his drag car and uses some alky.

Stock compression is sweet for the launch, adn the boost takes over afterwards. Bets of both worlds.Build a forged motor with stock compression and use an ems--man--totally sweet.

I dont see anything wrong with a 400 street car on pump gas.

OK, Ivan, I probably cannot afford this anyways, but how much would it cost for you to just build a 240sx for track racing?

I would actaully like it better if I could do all of that by myself and learn while doing it but I have no place to work on a car so much. I also know far less than I wish I knew and am quite afraid that I would mess something up and then just waste my money.

vvaffle- im a little more local to you, contact me about this and i could help you out

My honest opinion on the drop in CR from 9.5 to 8.8 is its undetectable by my a55-o-meter. Drivability is just like stock. I had the car out on the street and the off idle power is all there. I dont know, maybe the fresh motor added power and ballanced out the drop in CR . Even with the larger GT 35 variant turbo the spool up was fantastic. The boost comes on about 300 rpms later then the GT 32 variant previously on the car. On the dyno in fourth gear, base boost was made at 3750 rpms.

I can totally empathize with your situation. I was in the same position as you years and years ago. I had a desire but limited funds. I would suggest reading as much as you can. Get a copy of the FSM and figure out how everything works. Everything you need to know is right there. Learning about the performance end is easier theese days with the internet and forums like this. Read, listen, study.... Ask questions... become knowledgable and learn to sort thru the BS. Take things one step at a time and you will be ok.

As far as price to build a track car... Here is what I would do. Get yourself a car that you can dedicate to that purpose (not a daily driver) and figure out your ultimate goal for the car. In all racing weight is a huge factor. Remove everything from the car that wont get you to that goal but that you can live without. Then work on safety related things like brakes, handeling, harnesses etc. Then start working on the power end of it. As you start hitting limits (open diff, stock clutch, stock suspension) then address those. Try to plan things out so you dont have to buy things you will not be able to use later (unless those things can easily be sold for close to what you paid for them) Keep going untill you hit your goals.

Wow, I'm going to sound like a noob but what does FSM stand for?
