I'm pretty sure this is the same (or damn close!) to the "book PC" thing - but anyhow - this is what I've got here that was (is?) going into my car, along with a Lilliput 7" touchscreen monitor (it's the shiznit yo!).
I actually live in KS...Name is "FastIndy" cause it's an Indy Pace car...and...yeah. Indy Pace Car.
All good things come from Kansas! hehe Nice to see you puttin ks on the map, bout time toto was forgotten. anyways, I love your motor! one thing, how are you gonna connect your lines to your injectors? I have about the same setup on my 4.5, less flowing of course, but I dont have the injector pod, just an injector boss welded to the intake. Is there any way to put lines straight to the injector, or am I gonna have to trash my setup for yours? Sorry for stealin your thread, just really burnt out not havin my car runnin. thanks, and good luck.
------------------ Soon to be custom port fuel injected with Megasquirt! 4.5l and th-440 And Im only 18. think about when Im 30!!

Here's a mock-up photo. Instead of the big coiled up line just imagine it connecting to a fitting on the fuel rail. Depending on how your bosses are welded in, you could probably save a lot of hassle over my setup. If the injector bosses are fairly parallel to each other and about the same height, all you have to do is get the fuel rail machined with bores with the right spacing to slide over the top of the injectors, then make a bracket to keep the rail in place.
No real updates yet, working on the piston issue still. I'm also trying to figure out some ideas for a low-mount alternator. On that topic, if anyone has a spare A/C bracket laying around for cheap, I'm needing one...

Nice, mine isnt lined up at all, they are kinda kinda paired though, groups of 2, they arent even the same height though. oh well, I think Ive decided to go back to the 2.8 I have lyin around, at least it will run. thanks

Going back to TBI wouldn't really be that big of a loss. It's a heck of alot better than a 2.8. You could just cap off the bosses for now and worry about it later.

so true, I will have to make up my mind next spring though. keep up the good work, I will be watchin. laters

Sooo, good news and bad news. I got a degree wheel and was setting it up, when I discovered that the SCAT crank is threaded for a different (yet unknown) balancer bolt. "Greeeeaaaat". So I set it up with the stock pulley, timing pointer, and dial indicator, sans the degree wheel that I spent $30 on.
Good news first.
The valves are going to be around .170 away from the piston near TDC. Exhaust valves are even further away at TDC.
The bad news: I've still got pistons that come out .065 below deck.
So now I'm faced with the dilemma of coming closer to 0 with my deck height and using a dished piston, or leaving these in there with which I acheive a very ideal compression ratio. On the other hand, the valve position does NOT make a custom piston mandatory as I first assumed, and I could probably get something pretty good, made for a turbo and nitrous, for cheaper than the $600-$700 that Arias and Ross quoted me. It very well could be worth it for the increase in quench that might decrease detonation and increase HP.
Okay...looks like 6-7 weeks for the pistons, once I get them ordered. I've decided to go through with it though, no reason to stop doing things right at this point in the build.
Still working on new pistons, my piston guy went on vacation. Doesn't he know there's more important things to do? If anyone wants my old (new) pistons/rings/wrist pins I'll sell the whole set of four for $200. The wrist pins are the only things that aren't new, and they're in good shape anyway.
I've been working recently on a more advanced aspect of this project, having to do with my goal of this being a very advanced and well instrumented engine, technologically. So, lately, I've been ironing out some details for a turbocharger tachometer. That way I will be able to monitor turbocharger speed, and hopefully optimize efficiency. The plan I'm working on for right now is to use an IR LED and IR sensor mounted in the compressor housing to sense whenever a reflective surface passes by. This will give me a very definite hz reading for any RPM.

Sooooo...more details of that soon
Wow. Sounds almost impossible... Would be sweet as hell tho. Wait ---- you just wanna be a ricer and have about 28,463 gauges in your dash, don't you???

I bet he would like to see where he is on the efficiency map by looking at only his pressure ratio and compressor speed.
Wow - what a tach-y setup ! Actually, that sounds pretty cool. Years ago I used to think it'd be neat to have a turbo-tach on my turbocharged Corvair, just to be able to know how fast it spun. IIRC, the Clymer manual said the Corvair's turbocharger went as fast as 70,000 rpm (or some such figure), so thought it would be neat to see if it really did so.
Nate, my initial reaction was that an optical pickup wouldn't be good, but that's probably only because my Corvair's compressor wheel was usually carboned up when I looked at it, and that picture is stuck in my mind. It had a sideways carburetor that fed the compressor, so air/fuel mixture left deposits on the impeller blades, I guess. On the other hand, yours will be fuel injected, so the compressor only sees filtered air, and the blades probably stay nice and clean. A really cool idea, however you make it work.
Hey- if you came up with software that reads the optical sensor, and converts it into an rpm output for a gage on the dash, you might call it (yes ) -"Turbo Tachs." Oops! That name's taken already...

Wow, I knew there was another Fiero nut in this town, but I didn't realize there were more than that.
I just wish it were possible for me to see this Indy all put together before I leave. (Fiance insists on living in Toronto, and seeing as she's the big breadwinner she wins that argument. Not that I'm complaining. Much.)
Someday I'll have a Fiero again... "Hey hon, look what followed me home! Can I keep it?"
The only question I've got for you is "how exactly do you plan on keeping the front end on the pavement?"

The extra 40-50 lbs of methanol over the front wheels should help some...
Or not.
Canada, eh? When are you leaving? I'll try to have it done before then...but, well, you know.
Parts list is finalized, I'm going to get the components here pretty soon and put together a rough circuit. Here's the PCB I designed provided the damn thing actually works. If it works, I'll sell a PCB, display, and odds/ends kit for under $100,
Well we're on a bit of a shoe string budget at the moment. She's up there now, got a basic "pays the rent" job for the holiday season and is looking for "real" work. The aim is to get me there in time for the wedding in mid-April. I don't make much (any) money right now as a writer, so the big question is how best to cheaply get me and all the various material goods up there - not the easiest thing to manage especially since I can't legally drive at the moment (no car, no license... haven't needed either for a few years.)
So yeah, the "when" is more than a bit fuzzy right now. It depends mainly on how quickly she can find a job in PR (her career field) and have me shipped up there.
I'll admit, I'm something of a "kept man". But you won't hear me complain. She pays the bills, leaving me with ample time to make 100% certain she's blissfully happy. Win-win.
I'm also going to start working on a trans mount starter. My button flywheel for a 5.5" 3 disc clutch will be here soon also. No work on the turbo tach recently.
Well, I got my new pistons today and they look absolutely sweet, except that I wanted a deeper, lower diameter recess cut instead of the way they did it. So any quench I was looking to gain with these pistons was probably eliminated.
Sigh...
My mistake, however, as I didn't specify that I wanted an inverted-D cut before the shop ordered them. Oh well, I've reached the end of the road as far as pistons go, and these look to be very nice pieces that will take whatever I throw at them. I'm somewhat disapointed, but at $700, I feel it is unnecessary to go through this again. Granted, it wouldn't be quite that much, since I got pins and rings as well, but hey, I've still got other stuff to pay for.
Anyway, I just had an absolutely fantastic chat with bryson's (turbo Q4) dad, who informed me that my head and valves are coated and ready to ship. Thanks for the call, and most definitely call again, I'd love to talk about engine management for your project.
So, what this means is that my build is now down to the clutch situation, getting the pistons installed, getting pushrods of the correct length, and exhaust/intake work. I can't believe I'm on the home stretch already. Anyway, updates about critical (read: expensive) items may be few and far between from here out, as I'm going back to school tomorrow, but I'm always working on something and will keep this thread updated with respect to that.
I got my head and valves back from ceramic coating from forum member bryson. All I can say is wow, great job, and thanks. It looks fantastic. I will miss the uber-cool-looking shiny aluminum/stainless steel look from the past, but this coating is sweet and should help the performance among other aspects like operating temp. Pics (duh):
