I just got done with my LS/Vtec conversion, I just put the GSR head on cause the LS motor was already in my car so I never took out the motor. I start the car, it revs up to like 2K and then shuts off after like 2 seconds. Once I gave it some gas and it kept sputtering with me playing with the pedal. I dont know if its the injectors, because I had to cut the wires and lengthen them, but I'm pretty sure I wired them correctly.

Could it be my 3 bar MAP sensor, I just wired it up while I was doing the conversion. I thought I did it right too. The vacumn source going to it comes off the back of the manifold, it doesnt go before the TB does it? I'm gonna wire up the stock MAP today and retry it.
How do I check the injectors to see if they are wired up right, I marked them and put them back in the same plugs so thats not the prob. Can anyone else think of anything it might be??

Setup:
Ls/Vtec Turbo
01' B18B1 block
'95 GSR block
stock P72 w/ conversion harness
LS TB- Edelbrock IM
no knock sensor, bypassed Vtec pressure switch...thats all I can think of now
Please just tell me anything you guys can think of, this is my first time doing this so I have no idea.

 

bump, i guess you guys dont come out until it gets dark

A three bar map with a stock ecu. I don't think that will work too good.

 

yep, that was it

 

i say go with a chipped P28, runs better

 

I was told to get the P72 so I could drive it right away without getting it tuned-- cause im short on cash and this is my only car. Its working now and I am going to get it tuned with Uberdata soon so it should be fine.
