Tiny update:

Hello, I just wanted to give my thread a little bump. I haven't had much time to do anything to this car with yet another new job. But here is a quick update. I installed the Hedman headers that we purchased a couple days ago. They're definitely not the same quality that they used to be. They're in, and they will work for this application, but I would definitely recommend looking into a different set if I had to do it over again. The gauge of steel was very thin, and the fit and finish is horrible. Quality aside, I think the exhaust system is going to flow very well. The entire exhaust system is going to be 2 1/2 inches in diameter from start to finish with the an Integrated X-pipe and two bullet cats to appease our wonderful state and federal governments. The exhaust system is supposed to be stainless from the headers back, but an error was made in ordering and what arrived at the front door was in fact regular steel, instead of stainless pipe. The good news is I have a mid welder, and it's easier to weld what was purchased; the bad news is that I have a mid welder, and the exhaust system would come out much better if I had a TIG welder. I am very interested in learning to TIG weld and am trying to put together about $1k-1500 for a good quality used welder... but I won't be purchasing that till spring. Aside from how the welds look, I am happy with how it came together so far. I tried stitch welding the bead to make it look like tig, but unfortunately it still looks like sloppy mig welds. One section I decided to keep welding, then grinding, and then welding, and then grinding, until it looked like it was one consistent pipe with no welds. This came out nice, however it took well over an hour to do just 1 weld, and I deemed it completely unnecessary. Anyway enough Babble, most of you are not going to read any of this anyway, so I'll just post the picture.

No idea, but I bought the SAME SET for my 89 back in 05 maybe 06 and I remembered them to be great quality and value for the price. That's why they were the go to on this project. But the fitment and quality has really let me down.

If I had to guess I'd say it was exactly the same reason as everything else nowadays, Cost cutting measures...

We found a solution to our current Miniram dilemma.

I am the play it safe, play it by the book guy. If there is a procedure to follow I try and follow it. My father is the "fabricator." So we re-evaluated the intake. The cylinder heads that are on the motor are the original L98 heads that have been ported to death. After doing a little measuring we found the new port size was only .10 smaller in circumference than the miniram (.05 on each side); and a 1205 gasket seemed to fit like a glove. Spoke to our engine builder first of course. He agreed that in most cases its preferable to have a situation where either both head ports and intake parts are the same size OR head ports are larger than the intake ports. However seeing that the port size difference was so miniscule it would make little or no difference in HP and certainly nothing that could be felt on the street. So with a little machine work to the intake, some measurements, and some silicone that intake was installed.

Before we installed the intake we filled the engine with Joe Gibbs BR. Then I proceeded to spin the oil pump to build pressure; only to realize I forgot to install the oil temp sensor. This lift a nice big puddle of $12 per qt of Break in oil on the garage floor.

I used a little permatex thread sealer on the bolts surrounding water jackets.

Tomorrow the car is supposed to be completed. I will not run because we need to have the PCM tuned, however it should at the very least look like a car.

Well, we still have the one for the 91 sitting around, but I am reluctant to use it. At this point I will search for one till the very last minute, then I will just toss in one for the 91 and hope it works.

Not sure if it will work or not.

Here is the bulletin for the codes and clearing them, applying the grease etc:

BTW, the part number for the 1990 SIR sensor is 10094613.

We spent the better part of the day working on the vette, however we did fall short of some of my expectations as well as ran into a couple of small issues.

Of the progress we made, we were able to completely finish the exhaust, move the sensors over onto our new throttle body, prime the engine correctly, and install A distributor. I am not really sure why but the specified Jegs distributor that was ordered did not fit. It was labeled for 85-91 TPI Engines however the plugs were different and the distributor sat way to high. I have no idea what would cause this. While down in the basement yesterday looking for something completely unrelated I stumbled across an HEI unit off one of his 87 corvettes of the past. The unit fit perfectly. He has so much into this vehicle already, I decided to stick with the HEI and return the aftermarket jegs version. I will take the return money and order a new MSD cap, rotor, coil to "boost up" (yea right, more like look better) the old distributor and use that. With that little bump in the road, most the day was used up. Still deciding if I want to wire in the MDS 6AL now with the HEI unit.

Here are a couple of pics of the most recent progress.

And I wouldn't use the MSD box... all it does is arc weld the cap/rotor contacts, then it blows up for no good reason.

You won't be spinning enough revs to make it matter, either.

And personally, if multi-spark-discharge was really that great, OEM would have adopted it with these coil on plug systems, but haven't.

Is there a source where I can get the wiring harness connectors for this vehicle?

It seems as though the transmission speed sensor for the zf6 on a 90 is different from the one on a 91 even though they are both black tags. I broke the sensor trying to get it out, to install one from a 91, only to realize when I got it out that they were different and the 91 won't fit. So my idea now is to replace the sensor and than change the connector to fit... but not sure if it's even possible to get one. Hopefully I don't have to find a 90 harness to cut up...

Try ZF6doc?

JEGS has the TOOLS for GM connectors - re-pinning, that is; I imagine if they have service tools for the connectors, they might also have connectors...

Junkyard? Check the Hollander # for the tranny; go from there.

Good work too! Maybe get thread title changed, for reference, search source, hit count boost.

I know its been a year since my last post in this thread but we I wanted to bring some closure to it. We had some free time this week to button it up a little bit and the car is 95% done. It runs, we found a dipstick for it that fits. The only thing left is to install the air conditioning and get it tuned. It seems to be running very lean, and on the stock tune it will idle but is barely drivable. I did take it up and down the driveway just to make sure the clutch engages and it seems good to go. This week my father scheduled someone to come and replace the broken windshield. Overall we are both very impressed by how it came out and were glad we saved another C4!

Now the next hurdle is finding someone to tune it. There doesn't seem to be many out there still working on PROM cars at least not from what I can find. Does anyone know anyone decent we can bring it to, to have it tuned properly. We are located in Orange County, NY so the best bet would be someone in the NY, NJ, PA tri-state area.

Glad to see it up and running!

PCM4Less for tuning. They will do it mail order, you install the chip and adapter in the PROM slot, then hook up your laptop with and ALDL cable and datamaster/tunercat and get some readings and they fine tune it. Around $225-250 last time I checked. Very good reputation.

No kidding?? I've heard of tuning done where you can send back the data logging over the internet and they make the necessary changes and send you back the new info. Is this what you are referring to?

Exactly. You will need to buy an ALDL cable if you don't already have one. You can order it from Moates.net. The laptop software is free on the internet. If you want to buy your own chip burner, that is additional, otherwise you can send chips back and forth.

Some updates:

New Windshield

Resized Image

And a new roof that doesn't match and needs to be painted

Resized Image

And some new shoes... 17's and 18'S

Resized Image

Its coming along nicely. I ordered a Receiver Dryer tonight and a Variable Orifice Valve for a 1994 Corvette tonight. My plan is to install the compressor next week and retrofit the A/C for 134a.

Spoke to a local shop today that has a Dyno. They have a tuner they use. Their not sure he does PROM but if he doesn't we will rent the dyno and I will contact PCM's for less and attempt it that way.

That was a very helpful site. Just learned that the yellow Ebay Injectors we purchased are 19lbs instead of 22lbs which they are supposed to be which is probably why this thing is running super lean... in any event they will never work on this motor, so we definitely have to address this before we dyno the car.

One random question I just remembered which I will post now before I forget. Apparently my machinist installed a high pressure oil pump in this engine as it is running at 80psi cold and 70psi hot (no loss of oil pressure here). I am running Joe Gibbs BR30 at the moment, but I'm going to dump it out soon and put in some Mobil 1. They recommended a 10w-30 for it, but do you think it might make more sense to run a 5w-30?

Did they have any issues with the windshield? They can be tough to put in.

As far as the injectors, tell me what part number you have and I'll check it. That site doesn't say they are 19 lb injectors, it says he had to change the programming tables to adjust the flow.

Do you plan on running it in cold weather? 5w30 isn't necessary, 10w30 is fine. Joe Gibbs has high quality oil. I personally run Mobil 1 synthetic.

The windshield was outsourced. We had someone come by and install it. It was an older gentleman who claimed he had done quite a few in his time. He didn't seem to have any trouble getting the job done so I would assume it was fairly easy.

The numbers are the injectors are so small I can't see them. I need to grab a magnifying glass and I can get those for you.

10w-30 it is..

AIR CONDITIONING:

So today we decided to tackle the air conditioning. My original plan was to convert the system from R12 to 134a. I've converted systems before with mediocre results. I have been reading conflicting information online about how to convert the corvette system over. Some say drain the mineral oil and add PAG 100, others say use 150 and then there are sites that recommend PAG 46; then there are those who use ester oil because they believe PAG oil to be corrosive. I haven't honestly had the time to do the thorough research on this I would normally do, to get the job completed right. I have a good compressor and a new receiver dryer. The original orifice tube is in good shape. I have 3 cans of R12. What do you guys think. Convert it, or replace the o-rings and put back in the R-12??


One thing I am having trouble locating is an oil capacity chart for this car. My crappy FSM doesn't seem to have it. If anyone can post one that would be really helpful.

TUNING:

Looking like my original plan to have someone locally Dyno tune this is a fail. I don't know if it is any more or less complex than an OBD 2 car, but there doesn't seem to be any interest at all in doing it. It's looking like Matt's recommendation has been the best so far. Since we have done everything except the engine refresh and windshield in this car I am tossing over the idea of buying all the equipment required to tune it myself. Yes, I know; I don't need a lecture on how complicated tuning is, Ill be the first one to say I only loosely grasp the basic concepts, but how are you going to learn if you don't give it a shot. I understand how the different systems work together so the car runs. My Friend knows very little about fuel injection controls on a vehicle but is great with computer systems and programming. We spoke about a collaborative attempt to tune this vehicle together this past weekend. He's in if I purchase the equipment. So do two guys who know a little = one tuner? Maybe we will find out.

What equipment do I need to purchase from Moates to data log and tune? Which is the preferred program to use for a novice... or should I say novices?

Buy a new orifice tube, it's $3.

Offhand I don't recall the oil I used for my conversion, I will have to check. If you are certain the system is leak free, use the r12. It will cool slightly better, but not much. If r134 you use approximately 80% of the fill weight. You need gauges to go by pressure, though. As far as oil capacity, the fsm lists how much to add for each component replaced.

I personally will not tune mine alone. People have said it's easy once you get the hang of it, but it's a steep learning curve. Lots of articles on TGO.

And for datalogging you need a data cable (about $60), a prom adapter (for new chip to install in the ecm), a chip reader/burner, and a free computer program like tunercat, etc.

Would the APU1 do everything I need it to do? I would like to be able to program the car in realtime like an OBD2 vehicle if it came down to it. I had my 89 programmed years back. I remember cracking open the ECU and adding a chip, that was then removed, reprogrammed, and re-installed. Just want to make sure if I am going to spend $300 this will do everything I may ever need it to do.

Here is some info on oil amounts, but keep in mind these are with a empty system. Not just empty freon, but empty oil also.

You would also need a chip adapter and zif socket.

Just wanted to post an update. Was hanging by my engine builder and inquiring about a set of cylinder heads I plan to have them mil for my personal LQ4 Chevelle swap project I will hopefully be getting started on next. Turns out a year or two later (?) they had a note book page with everything they did to this engine including measurements. So we made the executive decision to outsource the tuning to PCMs of NC (PCMS4LESS). I felt confident with all the information I had they could put together a fairly close chip. The car is not going to be a race car, just a quick cruiser really. So squeezing out every last pony really isn't top priority. I am highly inexperienced in tuning so this would have been something that would have probably taken all summer to get right and even then there is no guarantee I will be successful. This is a quick short cut to getting the project done fast and being able to use the car all summer.

So just for reference (so I can look back in a few years). The heads are fully ported and a 3 angle valve job was done. Light milling was done to get the heads flat which caused a very slight bump in compression. It has a set of 1.7RR and the stock cam was advanced 4 degrees. The intake is a TPIS Mini Ram and we will be switching back over to the FORD/BOSCH 38lb/hr injectors this weekend. The car has a set of full length headers into a set of high flow cats. The exhaust was custom fabbed by me and goes into an X-pipe with Dual borla mufflers.


This past week Dad installed all new moldings around the doors, windshield, windows, and the rear trunk glass.


The remainder of the checklist includes:

1. Swapping Injectors again
2. Mounting Coil properly
3. Completing A/C System
4. Install new chip
5. Timing


Trying to get this all done this weekend, so I can enter it in a vintage car cruise/rally next weekend. We will see how it works out.

Pics and Video's to follow,

DG

Thanks for the update. I think you made the right choice with the chip.

It's been a long 2 years, but your Dad will have one sweet Vette when this is all done!!!

I was re-reading some of the original posts... man, what a mess that tech left.

Hello Everyone,

Happy belated 4th this 2015. I haven't had an opportunity to post in a while over here so you all missed the Saga and drama. So to get you all up to date, a month ago we sent out for the mail order tune and the chip returned tuned for the 38lb ford injectors. Right from the get go we ran into problems. Car went from barely running to not running at all. Pulled the plugs and they were wet. Did some reading online and realized 38lbs is way to big. So we sent the chip out again and had it re tuned for 22lbs. The Ford Blue injectors were too big so we swapped over to a set of EBAY yellow 22lb injectors which are listed all over the place online. A while back I remember reading that there were issues with those injectors but my father not realizing purchased them anyway. We sent the tune out and had it re tuned a second time for 22lb injectors. Got it back, car was running but really poorly. I was beating myself up over the past couple of weeks; checking over all my work, wires, vacuum check, and so on. Couldn't figure it out. For kicks today I went back into the ECU to make sure the chip was properly seated. While I was in there I decided to pull the tune/chip and install the original chip for the vehicle. For the first time to date car started up and idled normally. Still runs a little off but in comparison its 95% to where it should be. I attribute that to the fact that the cam is degreed, there is no egr, and no air pump any longer, and we are running a stock tune with a tpis miniram. So, this is where we stand: Do not purchase cheap ebay yellow injectors they are not 22lb injectors as stated in the listing, they are 19lbs. I am going to purchase a new, quality set of 22lb injectors from a reputable source and install them with the mail order tune. One a side note I was able to drive the car for the first time today. Took it up and down my road, got it up to 50 mph. It seems like it has the potential to be a very nice car. I will post video at the conclusion.

lb/hr is meaningless if you don't know what psi it's rated at. I'm sure those 19# will do 22# at a higher pressure. I think GM used "24 lb" injectors in 85 and "22 lb" injectors later, just to give you an idea.

Some manufacturers rate at 39psi, some at 43.5psi, etc.
