Mine is a S4 so it's not electrical and I have it blocked off.
The ecu is N341 from a J spec 87 turbo vert.
I swapped the trailing coil at the time I did the timing.
Any progress on your swap?

I thought the pressure vs voltage readings where different between s5 and s4.... the 370 is for an s5 and you said you ecu is s4...

mikey1992

I have no idea if it is or not, but that would make sense.
Well now I'm in the market for a S4 T2 boost sensor.
I used the N370 when I was NA and using the N326 ecu and it worked fine.

No progress. Just gonna sell it and buy a tii and mod the **** outta it, lol.

You are having the same probs as i did. Check air flow meter, tps, cas, fuel pump voltage, vacuum leaks, boost sensor voltage, exhaust leaks before the downpipe.

mikey1992

I don't think you should sell it.
I'm almost positive that the boost sensor is my problem.
Aaron cake posted explaining the difference in the sensor for S4 vs S5.
How long have you been diagnosing the car?

No doubt id try fixing it. If you sold it and found out the guy fixed it and it was something easy youll be pulling your hair out.

Its hard to diagnose when the tranny is making it to where i cant start it and diagnose while running. Need to get a tranny for little to nothing for me to be able to keep it. I wish i could find an unmolested tii for a steal.

Gonna be hard to find that, most rx7s that are clean aren't going to be cheap. Once in a while I'll see one that looks clean for cheap, but usually very far away.

You could probably find a transmission cheap.

I ended up having to junk a turbo2 rx7 that still had full drivetrain on it because of my landlord selling the house :/

I woulda sold the transmission cheap if I still had it. People seem to think their rx7 parts are gold , asking 250 for a transmission used.

Honestly I think if you looked around you could find one for half that.

Just ordered the N318 boost sensor.
I have 3 transmissions and 5 engines.
I stock up so I have everything I'll ever need.
Really hope you don't sell it cuz you'll end up missing it.

blackrotary23

I need n/a tranny right now. Just so its drivable. Swapping drivetrain this spring if i keep it.

Update:

Transmission is out, compression on front is 89 on rear is 92, wire harnesses out tomorrow for inspection, all electrical components out for inspection and testing as well, fuel injectors are getting cleaned. Check this out: service your own injectors.....

Spun a rotor bearing. I knew there was something wrong

you disassembled the whole engine to find that out ?

blackrotary23

I knew i spun at least one bearing, but i tore it down to see how bad it was. Found that both rotor bearings went along with e shaft, oil pump and both stationary gears as well. Thermo pellet stuck closed due to the previous owner overheating the damn thing over and over.
