Failed Injectors...ouch
Well, back in August I decided to finally bite the bullet and go FI. What a journey it has been. I didn't stop there though. I figured my wife wouldn't allow me to do anything else later on, so I went all out. So many stories(which I'm sure i'll get around to posting in the appropriate fourms).
I finally got all the mechanical work completed a while back, my compliments to Marko and his crew down at Forcefed Racing in Langly B.C. I've never seen so much horse power just laying around. They specialize in 3 rotor, big boost setups(40lb RX-7's & FD's). All "one off" stuff.
Minus a few setbacks and minor issues, things went fine. I brought the car back to the island on a fri night. On the way home, all I could think about was, what was left. Just suspension and bodywork.
The coilovers were still on the way from Japan. Last I heard from Joe at PTP their ETA was 1st, 2nd week of Nov. The sways and strut towers.... here collecting dust, waiting for big brother.
As far as the body is concerned, I was dropping the car off on Monady. The plan, A week, a week and a half tops. Things were lookin' great.
Saturday was fun. I put her to the wood a couple times. Nothing crazy of coarse. I didn't rip apart every intersection I stopped at. After all, I still had the break in period to concider. It's hard to drive while your eyes are clued to the A/F buy the way.
Sunday...Bloody Sunday..
I was dropping off a buddy at 7:00 am ish. Not a car on the road. Perfect.
1st gear, I squeeze and keep it on the edge of wheel hop. 2nd gear, I squeezed into it untill around 5000rpm then I got on the goose. WoW. I took third with the sound of the HKS SSQV waking up the nieghborhood(not to mention the AP exhuast) and thought "break in period". So I popped her into 4th a coasted down the hill for about 20 seconds. That's when the exhuast note started to sound funny..I touch the trottle...nothing, no power. Drop it down a gear..nothing no throttle response. The engine is still running but it sounds like its choking. Just as I start to turn into a driveway, she dies.Through out the whole pull the A/F was perfect, low 11's.
I called marko from the side of the road. He helped me to do some trouble shooting. Meanwhile, every time I turn the ignition the 1000cc injector(vendor to be named in a different thread....Oh fu*k it..) supplied by ESMERIL RACING, is now stuck open, it's filling the engine. Enough to start leaking out the exhust manifold. Nice.. Towed it home. Sunday...Bloody sunday.
Monday......Had the car towed to Progressive Motorsports. They called at the end of the day and told me they had never seen a fuel leak of that magnitude before. Took 8 days(nice number don't you think) to get 1000cc injectors.
Next week Tuesday pm....I picked up the car. Drove around a bit and kept my eyes on the A/F. It seemed fine. Oil Temp and Press were fine as well. The fuel pressure was acting up a little. Not the normal 59-61. At times it would be jumpy. Going up to as high as 75.(let the record show..Fuel pump is the ESMERIL RACING upgrade. Just in case).
Wednesday.....I talked with Marko and made arrangments to get the car back on the dyno. Make sure everything was okay with the new injectors.
Friday....Drive the car to Langley. Stalled once at a red light. On the way I call Progressive and ask them if they changed the oil. Nope....Nice.. 1st Thing they do at Forcefed is drain the oil. It's full of fuel....nice...New oil and run the car for a bit and change the oil again. Up to this point, other than the fuel pressure and the stall, things seemed normal. They put it on the dyno and did a very short pull. He said he had the boost set at 13lbs. It never made it to 13. Around 9lbs he said there was a hicup or something. Not a Ping or Bang. Durning the pull one of the guys had the earphones on, listining for pings. Nothing. Second pull, if you could call it that, wasn't very long. Lasted about 3-4 seconds before he got off the gas. When the engine got back to idle speeds it just died. They did a comp test on both rotors. number 1 is dead. The one that had the fu*ked injector. Number 2 perfect. They are ripping it apart to find out exactly whats what. I'll know Monday.
The positive in all of this is this.
I have decided to get her new seals, get her ported, and pinned. New goal is around 20-25lbs and around 400+hp.
Can't wait for the wife to get back from Seattle so I can tell her
Any ideas when the engine let go? Like I said nothing seemed out or the ordinary other then the fuel pressure. Any and all input would be great.

Sounds like he's using the ESMERIL RACING turbo kit, though he never specified. If he is, he should read this post. They got 414WHP @ 16 PSI. My guess is, he's trusting this shop's word because they do "big boost setups" in FDs running 40 psi. All I can say is, read olddraggers post again:
Your buddies at that shop will probably do whatever you say, you want 20psi? 25 psi? ***** and grins to them, just more money when they have to rebuild your engine again.

[QUOTE=simplyphp;2709775]Best of luck to him, I just don't want to read him bitching about how nobody warned him and now he has to get his Renny rebuilt (again). QUOTE]
Too true. If he is going too push futher than others have, there better not be bitching if it doesnt't work out the first try.

Ya my mistate. I did have my numbers off didn't I.
Well I didn't get the 8 motor rebuilt. I decided to go with the 3rd gen FD REW swap. Only took Marko and his crew 3 weeks to pull it off. I'm glad I chose this route. She's ready for 700+ whp but that will have to wait for a new tranny and a bigger turbo. I'm still running the turbo that comes with the PTP kit so I'll just have to settle for the 350 whp at 7400 RPM with 9 Lbs of boost. Still some minor tweeking to do. Marko tells me that we'll get her up to 14 Lbs with about 400 whp.

uhh, the wife comment..no I don't. I'm still choking up pieces of my *****. As for what was involved. I didn't do the work myself. I don't know to much about the real fine details like as in step one, step two, but ask me some specific questions and we'll see if I can answer them.
When this engine goes I might go that route.......Especially now that he has done it once
