I dont think you can do it on the KA. Show me someone who is running over 350hp on a KA engine or show me someone who is running NOS on it. I saw a pic of the sidewalls on the KA engine and there isnt even enough room to bore it out to allow for aftermarket pistons. You would have to be pushing around 17psi on the turbo to make say 350hp to the wheels and to then add a 50 shot of nos on there...your sidewalls would blow everywhere into your cylinders and then probably start shooting pistons everywhere since they would catch the broken walls and shatter your rods. I dont know a whole lot about the KA, but I know about boost, and I think that although the KA engine is very reliable, it isnt made to take that much stress. 350hp on a BUILT KA is #### good, but thats only my opinion. You want 400+hp, use the sr20, its made for that.
</td></tr></table><span id='postcolor'>well his car just dynoed at 392hp, so will see tomorrow at the track
just got back from the track tonight..11.9 @ 120mph. I think he was running 20psi, no nitrous.
Just keeping this post updated, cuz he reached his goal of hitting 11's.
BTW, this is a street driven car with full interior. I cant wait to get my S14!
Ok heres pics of his car. This is before the haltech. It's a t-60-1 ball bearing with 8:1 compression piston, stock head, 720 ccinjectors,
jwt fuel rail, 300zx fuel pump, automotive FPR ,haltech DFI ,trust intercooler, ceramic coated exhaust manifold and turbo with Revhard exhaust manifold , The Haletch was installed and tuned at Texas Performance Innovations in Houston. Any questions feel free to email them at [email protected]

The 240 is mostly stock except for forged pistons and rods. The CR is 8.5:1. The head remains stock and is also using the stock head gasket.. the suspension still needs a lot of work. the car will not transfer weight very well and we cant lay down the power off the line. we still have a lot more left in it and we will continue to progress.

Also My KA has been bored .5 over the equivelent of 20 thousanths of an inch, I am hoping for the same numbers as this car because we basically have the same setup, I will have a custom short runner intake manifold and be hitting 25 psi so maybe I can get a little more out of it. I'll keep everyone updated
