Happy New Year everyone. I think I have my injectors swapped on my car. I didn't do it. Car was running like crap. It was tuned though by Steve Kan, I would think he would have noticed them while he was tuning it. I ordered one new fuel injector from RX7 store. A primary or a lest I hope so. The one in the pic. on the floor is the primary. Bur on my set up that same injector is in the sec. fuel rail!

The injectors that are in the primary rail have a sliver top, are those possibly prim? WOW! please someone take a look at this cluster. I know the injectors that are close together are the prim. and the short fuel rail is the prim. the long rail is the sec. Right? please help asap.

 

I just found out that the injector in the pic was a sec. SO maybe it was right. I guess RX7 store sent wrong one.

 

My bad Jason I ordered the wrong one. You sent the right one, I wanted a primary one.

 

What numbers did the car make and at what boost levels?

 

It was like 260whp. ( I think ) steve said that he thought the clutch was giving out. The clutch is new with 1000 miles on it. ACT 6 puck. Maybe that clutch wasn't enough. I was pretty disappointed in those numbers. Also everyone else cars were making very little to the wheels. The car was tuned in Oct. Also I had race 10's spark plugs in there. Took them out and put in 7 and 9's .
He was running 8psi. Last thing im going to do is change the fuel filter tomorrow. Im going to flip if this motor is blown. I broke it in the right way, pre-mix. everything done right. I guess last thing is to do is compression check.

 

You are only running 8psi?? Maybe I misread but those numbers don't really sound that low if you are only pushing that little boost. I don't think you lost the clutch due to it not being able to take it. Maybe if the clutch is dead it was not install correctly and not totally disengaging? Just a thought.

On my 500r setup I just run all 9's for plugs and they work just fine. Do you have some sort of ignition suppourt? Twin power? If not you will need it. You will get breakup at high rpm without it. For a comparison, Steve also tuned my car last summer and with stock ports at 15psi I put down a lil over 400whp.
