S5 TII swap finished but turbo wont spool and boggs when i step on it?!
1989 Na car,S4 motor, S5 manifolds and turbo, NA harness,no emissions,FMIC,3"straight pipe,JDM chipped ecu( used to run bigger turbo and injectors),N318 pressure sencor,JDM s5 AFM,720cc secondaries w/ wired in resistors,no boost gauge.
motor starts and seems to run fine,drives fine at low speeds,when i give it some gas it boggs out and i havent noticed the turbo spool once.its like when the turbo should start to spool it looses all power.the turbo looked to be in fine shape.
any ideas would be much appreciated THANKS!!!

just get the connectors cleaned up real good. use a thick sewing needle to swipe inside the metal connectors to get any possible rust out. doubt they rusted though, i believe they are stainless.
in order to run the turbo setup properly, you need the following:
t2 ecu
t2 engine wire harness
t2 boost pressure sensor
t2 throttle sensor
t2 mass air flow sensor
t2 fuel injectors
t2 fuel pump or fd fuel pump
t2 knock sensor
t2 fuel rails with stock or afterkmarket pressure regulator (if aftermarket, make sure you get at least 55-60 psi on it)

There's no need for a TII harness in any turbo swap.

actually..............n318 is the sensor number and the wire harness grounds differently and also the tps is wired differently. i took one apart and they dont match up 100%

also, i have a friend that runs a performance rotary shop and he even told me that to run a turbo setup on an n/a harness, you need to be able to program the throttle and air/fuel mixture.

Stop posting garbage. NA and TII TPS are wired the same. Look in the FSM.
Your friend doesn't know what he's talking about, and an N318 is an S4 MAP sensor.
N370 is S5 TII: http://www.mazdatrix.com/getprice.as...m=18-2110-N370

Ok so i installed the n370 pressure sencor and that same problem.i dont have to be driving if i step on the gas it falls on its face.if i slowly or normaly accelerate its fine.

ok then. so here is a question:
if some sensors match up, then if the car has "all" TII parts installed, does it need to have a TII wire harness as well?

Hey Marley this is Damien. I'm not sure if any of this would mater and you know I did the swap S5 engine to S4 body. I'm not sure how the Lower Compression Rotors from the S4 would have any conflict with the S5 ECU and all. Some may wanna flame me but it is a honest question cause this is my 1st RX7, but I'm not new to cars by a long shot...

As long as the electronics match you're golden. I'm running an S5 TII in in a S4 n/a car with S4 TII ecu and electronics and it runs great. And you definitely don't need a TII harness, it's easier to do it with the n/a harness.

i know he had large RC injectors i dont know what size or what rezistors.the only thing i know about the ecu is it has a mitsubishi relay attached to it thats not hooked up and it has "boost up"writen on it in sharpie.
my friend just scolded me cuz im using 89 gas and i havent checked the timming.he said it could be knocking and eating my timming? he also said "it could be the TPS but id better put 91 gas and check the timming asap!" :/ oops.

this may be unrelated but alot of fds have 3k hesitation and its because a lack of grounds or the battery cable to the engine being gunked up. maybe add a ground to the chassis and check the cables if all else fails
