okay i have a 1991 rx7 turbo 2, 13b single turbo, greddy fmic, piping, bov, and turbo, secondary injectors,turbo back exhaust, all emission devices have been deleted. okay so here is the problem, car starts idols fine, it drives fine as long as i stay out of boost. as so as i give a little throttle and go into boost, it starts to stall or bog kinda i guess i would say where the turbo should be spooling nothing is happening, i'd say as soo as i give it like anything more then like 15% throttle it just starts to die the motor wont rev you can floor it and nothing. its like the computer is maybe stopping it or something for some reason?i dont know if this make any sense.

what could it be?vaccume leak maybe?or a sensor somewhere that keep the car out of boost so you dont do damage maybe?any idea or things i can cheak would be greatly apprecitiated. thanks

check your afm. also make sure all your piping is tight and not leaking, and check your tps

 

i second that, is it a misfire kinda thing? you could have a massive boost leak. sometimes a couple will appear connected tight but under boost give out (check right off the turbo)

 

Overboost fuel-cut?
Are you running this thing in the stock ECU?

Larger secondary injectors without any means of turning the fuel supply down when they come in? Are there any fuel controllers installed?

I don't see the pressure sensor or idle control pot on the passenger shock tower. Have these been deleted? And if so, they need to be reinstalled.

Can we get a good shot of the engine bay showing it from the front of the car so we can see the whole thing and the extent to which this car has been hacked?

 

yes i will get a picture, i currently dont have the secondary injectors hooked up, as ive been having issues so thats one less thing i have to worry about when trying to fix her.

 

Oh god, get the car away from this guy...
*sigh*

The secondary injectors are necessary to run the car. If you go into boost without them, you will blow the engine.

Is this a former A-Spec car? (A-Spec in Toronto, not the A-Spec that sponsors this site).

 

yes it is, the secondary injectors are in the piping and are there for whatever you want to put in them, they are not factory. It was a TPS issue, car is fine now.

 

those aren't the secondary. they are AUXILIARY injectors. the secondary are mounted on the intake manifold.

 

well excuse me for calling them secondary....
