SR20 HELP! Motor just isnt runnng right Im too dumb to figure it out lol

[fwuffy squirrel]

Well this thread might start a little long so here I go.
I bought my car about a week ago and I knew it had problems but didnt think it would be this hard to figure out. the car has a SR20DET redtop stock everything pretty much. Front mount intercooler, bov, all that small stuff.
The car feels like its at around 100hp mabye 140 max. When I slightly push the gas it accels normally and you could hear turbo start to spool at about 2.5 mabye 3 so Im pretty sure the turbo is doing its job. But the rpm's go up WAY too slow in every gear. It feels super slow, slower then a stock motor. I drove my friends sr20 and its a world of difference. Anyway when you gas it about 30% it seems to be faster then 100%. in fact 100% throttle makes it a bit slower. Its really hard to describe with words but i'll try.
At 1-2rpm its great 2-3 you feel the turbo spool a little 3-4 you hear the turbo spool faster but the power from the turbo is literally GONE. In fact it actually slows the cars accel to where you feel like your not even pushing the gas pedal at all for a split second. and from 4-7 it jerks with power then no power about 3 or 4 times.
Ill try to illustrade though percentages
RPM's 1-------2-------3-------4-------5-------6-------7
Power 90%------100%------10-20%--50%10%60%10%60%

Sorry thats the best I could do. Now here is what I tried and found out about the car.
Me and my shop concluded that it wasnt loss in turbo or a leak because he said the welds on everything was good and you would hear an air leak when I gassed it. The throttle response is good and engine and turbo respond when they should. So we thought air or fuel.
I saw that one of my injecters was slightly higher and lightly leaking and even though I have an upgraded fuel pump, I could not be shooting enough fuel. So we took it out and the fuel rail was bent and the fuel presure regulator was "halfassed" with some acehardware bolt. So I bought a brand new fuel rail/fuel injecters/regulator from a stock SR20 redtop and installed. The thing fit nicely but in the end the car was still performing incredibly poorly. Before i left the last 2 things we could think of was either my Mas. A: Z32 mas might solve it because of the lack of air it allows or B: What I personally think it is, we fould out that my ECU was the stock 240 and not the SR20 one. I def hope that will solve everything.


Could you guys help me out please. If you have any Q's feel free to ask I will tell you anything.

I didn't even know you could run an SR20DET with a stock USDM ECU. Pretty sure that's it.

And you don't need a Z32 MAF with a stock SR.

[Sir]

hows timing?
maybe you ignitor is on the way out?

[fwuffy squirrel]

hmm not sure. Im not the smartest guy when it comes to cars. I found out my ******* didnt double check what the ecu was and it is a code 62 manual SR20 one......so now im stumped. What do you mean by ignitor? The guy said the timing was off when I bought it hmmm

[drifter808]

well if the timing was off when you bought it that could be a problem. have you ever checked it or adjusted the timing? have you checked the turbo for shaft play?
