HAving trouble with my KA-t need help fast

[s13drft89]

Well i got everything in, here is my setup ssa mani, garrett turbo internel wastegated, smic intercooler, cutom piping, 370cc injectors, stock maf, and apexi safc, and a generic BOV also i took of my egr, and replaced it with a block plate, and capped all the line going to it with screw and silicone, so it wont leak for sure. Well the car starts up fine, idles a little high, but i believe thats from the throttle cable, well i go out and try to rev the car, it only wants to rev between 2500-3000 rpms, my boost gauge reads 20 vacuum on idle, and when i rev is to arouns 2000 rpms it goes closer to 0 (boost side), iam running my boost gauge and bov from form the FPR, and my wastegate from the housing of the turbo, where it has a fitting from garrett. I dont know what to do, iam stuck, and ideas or suggestions, also my check engine light went on, i did the check for the code, and it read out only one code which was 33 which would be o2 sensor, but i dont think this is the reason why the car cant pass through 3k rpms, also get this when ever i barley just turn on the car, i push on the car it revs past 3k, and i then let the rpm's drop and i try it again and when it hits 2500-3000rpms it gets stuck their any help please thanks my aim name is s13drft89 thanks

my car did it one time a long time ago and i forgot to hook up the maf sensor do you have it hooked up if you do then i'm not sure

[Chezedik]

For sure, it sounds like limp home mode. Check the connections on TPS and MAF.

[Chezedik]

Oh, just thought. If you never had to read the codes before you may be reading 12.

All hose clamps tight? Maybe a boost leak can cause this. Your description is vauge, does the car shudder, die, or just stops going higher at 3K. It happening around 0 psi makes me wonder if its a leak.

[crzycav86]

Is it making any boost at all? Check the gap on your plugs. Set it to around .035

[Jookmasta]

make sure maf is hooked up. if it is, it may have unfortunately took a crap on u for some weird reason. as said before, ecu is in limp mode. check ur tps on ur safc and see what it says.

[s13drft89]

hey i got it figued out, i had accidently reversed the yellow, and white wire for the maf sensor, car passes 3k rpms(with the help of koukika240sx), but i believe i need to retard the timing, iam shooting flames through the exhaust to what degree should i retard it to?? i believe the internel wastegate it pushing 7-9psi, i havent got to drive the car to see the boost gauge due the oil coming between the head and block freakin car also thanks for all the input i appreciate it

[Chezedik]

So you say you are having a head gasket problem and you are worried about timing? It sounds to me like you may just be too rich. Unless your timing is advanced beyond TDC. This would require it to spark while the exhaust valve is open, or for the flame to still be spreading as it opens. In any event timing would have to be seriously F'd. That is why I would say look at fuel. If it is too rich, and it does not burn it all. Then the hot, unburnt fuel will burn when it hits oxygen (i.e. at the end of your tailpipe). But since you are boosting, you should probably check it with a WB before you trust me (1K mi away) to help you blow your motor.

[Jookmasta]

what size turbo are u running? i suggest base timing at 15 degrees.

[180sx]

FLAMES MEANS EXTRA FUEL ! BETTER RICH THAN SORRIE ! ALSO timing wise once on kae-t my distributor bolts weren't tighed after timing adjustment , and yah from shaking etc distributor advanced to the max, under 8 psi it took it no problem.

[Chezedik]

well put.

[s13drft89]

iam not sure of the turob iam using, i have pic's click on the link http://www.putfile.com/s13drft89 i think my timing is off, on the distur, also for the fuel, people of told me to run -27 across hi and low throttle for the fuel, i have 370cc injectors form a sr20det thanks for the help, also for my timijng what should i have it at, i think the internel wastegate is set at 7-9 psi

[Chezedik]

I think I have said it before. It looks like a T25, and bolts up like a T25, ya know what they say. The distributor doesn't control timing, at least on the 240sx. Turning the distributor will not change timing. Timing is controlled by the computer. To change it, you have to change idle with the TPS disconnected. It has been covered a bazillion times. I would tell you to search, but the search function seems to have failed for the time being. Anyway, point is, you were probably setting fuel for the T3, and I simply do not think it is what you have. The upside is that a T25 will scream, especially if it is the right A/R.

[Chezedik]

It may be a T28, which would be pretty close to the T3.

[s13drft89]

The housing is bigger then the t25(much), whatev i cant find out the size of it, i tried garrett's website etc, nothing

[Chezedik]

Yeah, it doesn't have the bolts on the front housing like a T25, it clamps down like a T3. But on the back it is definately a T25 flange. So I would say it is T28. But in any event, I would say it needs to find some dyno time.
