help with n/a turbo swap
well here is the problem i have a 88 rx7 se and the turbo motor is from a 88 10th ae so i take the ecu harness and the the long block. well i didn't get the cpu harness cause i didn't think that i would need it. now it seems like the fuel is cutting off. cause it will rev like it does with cold start up to 3000 and then i give it a little gas and then it dies down and shuts off. so i have the solenoid resistor and i have no where to plug it up to. it has 2 wires that are........
blue with red stripe
2 more that are
solid blue
1 black with white stripe
1 green with red stripe
that is the only thing that i can think of that i didn't hook up.
also i am running the n/a fuel pump. should i change that with a turbo one or could i run it with the n/a till i get a walbro255. thanks for any help. and also how could i use the stock boost gauge. thanks.....

oh so it is just not making enough fuel for the car to run. yeah i did also hook up the tII knock sensor. so then i relly don't have to hook up the solenoid resistor?

I HIGHLY doubt it's the fuel pump.
Technically you can still run a NA fuel pump but you would be more apt to max it out when going into boost.
It sounds like your car starts up then rev's up to 3k and dies out right?
If so then it is most likely your AFM. If it is unplugged or bad it will cause the car to start up and then die off. I think it has something to do with the fuel pump connection/wire in the AFM.
I would recommend a TII or Walbro pump before you start boosting though.
I would also recommend to put a Fuel pressure gauge inline so you can see your pressures.
My Walbro is killing off my pressure regulator and I'm doing 50psi as it's base rate.
Better off running rich than lean on a turbo car though.

see i thought that you could run a n/a fuel pump. i don't plan on maxing the boost out till i get a walbro and a aftermarket boost gauge. i just used the stock turboII afm and i just plugged in the one connector for it. it just seems like that there is something that is cutting the fuel cause it revs to 3k and then i can rev it like twice and then it will just die out i can never hold or get it to idle at all. any ideas on the wire that connects to the afm on the fuel pump.

well i have installed a tII fuel pump and it is still doing the same thing. what or how would i find the wire(fuel) in the afm that i could rewire to make my car work. i haven't been able to drive it in like three days.

I'd say it is the computer, how is your NA computer suppost to adjust for boost in your fuel curves when it was not designed to.
I'd say your car is doing you a favor by not letting you drive it. I am thinking dead engine in your future if this problem is not fixxed...
Constructive help: No vaccume leaks, AFM, CAS, or TPS, it really is the only thing that keeps them running.
