Next summer when I come up there, I'm going to have to bring my car so we can dominate some Mt. Washington road action. Don't know if I can keep up with a 2871R though. FIX YO SH*T!

ooh, sidenote: for the few seconds It runs (read struggles) I already see a variance building between cylinders in regards to EGT.

cant wait to load this bish up a hill in 4th gear 20psi and see how big a variance between cylinders.....yea im that retardedly head over heals about this car.

I didn't see this mentioned, but are your injector terminals plugged in the right order.

Injector # 1 the closest to the Cas,

white/blackwhite

Injector #2yellow/blackyellow

Injector #3Green/blackgreen

Injector #4blue/blackblue

take a wrench....... attach to each injector...... give it a decent tap with a hammer.... see if one of the injectors is stuck open/close.

being that you are rich....... it sounds like a vac leak.

how much much "in spec" is the resistor pack? stupid thing can be a real pain when it wants to be.

how much vac was it holding prior to installing the turbo? isnt 10 high? at idle it is supposed be -18 to -24ish isnt it(IIRC that was the concensus)?

is the waste gate line locked down properly?

variance in EGT suggest fuel is more in one cyclindar over another. can you get us a reading..... cyclindar 3 is supposed to be the leanest....

what about try running the engine... maf only.... and remove the IC piping. thus ruling out the turbo and making sure that maybe the turbo itself is the issue. run it NA..... it should idle anyway as it will be rich higher in the RPM band, but not when there is no boost. least then you could rule one more thing out.

Greg has a stock modified timing cover. You too can do that to your upper timing cover with hours and hours of time spent with a die grinder and some sand paper.

Greg, man, I just don't know. You had to have done something when you took it apart that you have since forgotten about. Is there a shop rag somewhere in the intercooler piping? Did you forget to hook your ground straps back up? I mean, that thing fired up instantly when I was there.

Oh yeah, if it has gotten much colder up there and you have the TB cracked for idle like I do, you might need to adjust the screw on there to adjust the amount of crack the TB has in it. I remember mine did the exact same thing when I was first trying to get it to run with MSII, and the TB plate being open too much or not enough will definitely cause that. Once I got the opening the right size, it idled like whoa. Of course it ran, it just didn't idle. Just a suggestion (thanks guy two posts above me).

UPDATE!!!!!

thanks everybody for all the advice and effort trying to help me get this pile sorted!

anywho, good news - modified upper timing cover seen in those pictures up there ended up being the culprit!! Not the one you saw Tim, that ones straight and Im assuming it has to do with both dowel pins being in place. The latest variation of cover only had one dowel pin aligning it.

HOOORAAAYYYY!!!!!!

***group - HUG***

thanks again guys, I'll get videos up of this pig soon!

I just read the last part of this thread, and when I read about the modified timing cover, I was going to say that I thought that could be a problem, but it looks like you already figured it out. Glad to hear you're back on the road again man.

G'day Greg, i found what user name you have, and your emails make more sense now, i thought that there was just some random person Emailing me saying that our CAS bracket won't work . Which it does.

It's weird that the CAS bracket caused the problem. The After market CAS bracket that we have designed only use the one dowel pin to locate the CAS and with the 15 or so that we have sold and the 3 different versions we have used on my car we have never had a problem. Also CAS problems cause the engine to not run at all so it if was a problem with the CAS it just wouldn't start. I think it's related to something else and in the process if refitting the factory cover you bumped/fixed it.The symptoms your were describing sound 100% like a AFM signal problem. In these cases the car will start and idle very rough and rich and when you give it a blip on the throttle it will just die.Just to see if i am right go out to your car, unplug the AFM and then start the car, if it does what it was doing before then you it was the AFM. Doing this won't hurt anything as as soon as you plug it back in it will run properly again.

It so barely ran it was incredible, made diagnosing the problem that much harder, but I love how the cover looks so Im going to give it another go and see if I cant get it to run again

So did the symptoms replicate what it was doing before with the AFM unpluged?

update: Turned out to not be the cover, rather a bad CAS that was dwindling on its last legs, and finally failed. All 4 of them actually. I have 4 sensors, 2 purchased from folks off this board, that are ****e.

Purchasing parts from people who part out their engines is a bad idea. They get parted because of underlying problems, a solution is never found, then everything gets sold. stupid, doesnt make sense, If I have a known bad part I throw it in the garbage, not pass my problems onto someone else.

so yeeap, I remember Jon (not_an SR) saying one of the joys of CA ownership is going through 10 CAS's before getting a good one!!

No joke, just ordered that one made of gold off ebay gabby!!

will be worth every penny in my eyes......this 2871 and a healthy/happy ignition curve really make this car come alive I tell u wut.

Do I dare even update this thread? f*cking mightaswell right.

so. did I chase myself in circles? you betchyourf*ckin' A*S I did.

When I first built this motor, I put Tomei 256 cams in it, with some forged pistons. Upon starting the fresh built motor, 15 dbtdc could only be acquired by fully advancing the piss out of the CAS. At this time, I wasnt even running a modified timing cover.

The car felt like a pile of crap, and EGT's soared. I complain it felt faster stock, tuner trys to explain the bigger turbo is laggier. My blood pressure raises a few points. It started and ran beutiful cruising, and idled well all of that shiz with the pfc/z32/660s. It just felt like crap under full power even though it made a 280whp peak on the dyno (float you saw the dyno graph at one point and mentioned the mid-range looking like crap) and the guy tuning the car kept telling me to get an sr20 cause Im all like "dude, this thing feels like sh*t" It pissed me off likea bastard! You saw that graph at a time I was trying to sell my s15 t28 remember Ryan? I said to myself, "im seeing 15* and the car runs well; I must just need a bigger turbocharger."

Theres also bunch of "timing drift" posts that I put up trying to diagnose it if you guys remember.

So I sell the s15t28 and install a 2871. Now I look back and think that spec R would have been plenty. O-well, not gonna dwell on it even though deep down I really want to. Give me that turbo back Nali!

This is where the nightmare begins, and I type stupider. Car runs, I swap turbo, car doesnt run. I take turbo and manifold off/on combined 6 times retracing my steps freaking out. I try different timing covers, different CAS's, ignitors, knock sensors, maf's etc. Cannot find problem, few other people cant find problem, guy who tunes my car cant find problem, I post this thread of desperation hoping a dead relative will see it and shine love on me or the gods will feel bad for me. Your guys/gals' suggestions were awsome but everything kept checking out. Blokes on sxoc tell me to look at cam splines, I look, they look fine I see half moon, whatever, its a brand new cam its not the problem. I push my car outside and put it under a car cover. Wow, sh*ts gettin deeep now, my cars outside at night!!?

week and a half later it comes back inside, I remove engine harness and test continuity of everysingle wire, from every single sensor/driver, from every single plug, back to the ECU. My blood pressure shoots to 150/90 ....aaawsoome. Test continuity of key wires in front half of chassis harness back to ECU, and fix my sh*tty effed up knock sensor circuitry (when you extend shielded wire, the shielding beneath the outer layer cannot touch the inner circuit below the second layer) I get all excited thinking I fixed it (even though wire job was recent and PFC doesnt care about knock) but my hopes get brutally smashed into the ground as the car sputters to life and barely runs.

I decide Im going to purchase a Haltech iiingine menegment seystem *strong australian accent* and have a friend of a friend who used to work at Haltech USA in California who lives back in NH now, come to my house to size up installing an E8. That night I dream about my exhaust camshaft I guess and wake up having to go downstairs and have a really good look at splines. I use a q-tip to clean all the grease out, then get a small profile pick to "feel" the splines and run the pick around the lil tit there. I notice the splines, are non existent. oooh snaap, I hear a car pulling in the driveway It must be Dave coming to talk Haltech with me. Dang, I have to tell Dave to cancel paperwork he started with his bros at Haltech, and feel like a dink cause I blew the whistle hard tellin him to get the ball rolling with the order. O-well, Im happy as all sh*t cause I found a real obvious problem; THE problem.

So I remove that awsome brand new tomei cam and slap a 20 year old exhaust cam back in there after carressing it a bit and guess what? da-da-da-daang - Yep, my car starts and runs amaazing and shoots 15* at an amazing, never before seen, joyus, almost fully retarded CAS position.

Snow covers everything right now, and salt is everywhere so I havent felt its awsomeness yet, but I know its there. I discovered the camshaft over a months ago now, and have continued buttoning up loose ends etc. I made a catch tank for the breather on the exhaust side, and another one will go next to it for the intake side, and the PCV is going to go to one of those ca16de breather boxes that sit in front of cylinder one behind the timing cover (sxoc).

and thats the end of my outrageously long (cliffnoted) story.
