Well, I finally drove my KA-T tonight.Ran pretty good until problems showed up.

Can you guys help me with these questions?

1. My ECU was throwing code "34". Which means knock sensor.The first thing that crossed our minds were that we didnt replace the knock sensor on the blcok from my old 91 KA to my current 95 KA (I have a 95 KA in my S13). Is this a possible problem? or is it just my knock sensor is screwed.?

2. I have a major exhaust leak coming from between the turbine and the flange (T3 super 60, 5 bolt flange). we didnt put any gasket on it because we dont have any.How do you guys do yours? where can I find this 5 bolt gasket? Im having a hard time finding it.

3 can you guys re check my vacuums?

first set:Intake Manifold -- divider#1: 1. FPR, 2. another divider -- divider#2: 1. boost gauge, 2. BOV

second set:Hotpipe niple -- external wastegate

Are we doing this correctly? any suggestions?

Well hopefully I can fix all of these by the end of this week...Thanks guys.

Here's some shot (taken a couple of hours ago)

Vacuum lines seem right to me, but what about the bigger tube that runs to the IACV? Did you hook it up to a pressurized pipe?

yes we did, I figured that if it was like that on my SR, then it would be fine on the KA. Is this a bad thing?

chances are, youre knock sensor is different. I have a 97 knock sensor w/ a 96 ecu, and I get the code as well. are you running the 91 or 95 ecu?

No, that's how it's supposed to be run. Just making sure you did it right, looks like you did.

Everything sounds pretty good, vacuum is right etc. As for your leak, in theory that junction doesn't need a gasket. In practice, its possible the surfaces aren't true enough to get away without one :( Thats unfortunate.

yea i have to agree with that... its just that the flange got warped whenever we were welding and making the downpipe.so oh well.. Now im thinking about getting some metal gasket material stuff and make my own gasket.this leak is getting pretty annoying...open dump WG + exhaust leak = 2x loud :(

Basically i got everything to run a little better than yesterday.apparently, my BOV(atmospheric) was leaking so 240 keyy suggested that I should stiffen it up.. I put some shims in my turboXS bov and it ran pretty good now.. still a bit rich though...

oh and that check engine light is not blinking anymore after 240_keyy resetted it last night..
