I was wrong but now we are getting somewhere!

[Steve Wood]

Rest a easy guys, I went to his house and look at the car and heard it run and there nothing wrong he has a few noisy lifters that you cant really hear them, Bill told him he might have 36lb injectors but no there red strip and there 38lb and he has a TT chip for 009. so there you go also the clacking at the front is his belt tensioner. End of report.

Be sure you double check the numbers on the injectors because the ring colors did not mean much after awhile.....I think I had some green striped injectors that were the same as the red stripes when it came to numbers...not to mention the early red stripes were called 40 lbs injectors, but I think they later went by 38.  The only thing I trust is the number

and which 009 chip does he have The 42.5 009 that later had another number?  Does he need a chip then? 

What about the metal in the oil?  Or was there ever any metal in the oil?  What about oil pressure of 20 psi on 20-50 oil?

Steve i did't see the oil pressure when the car was running because i was getting gas out, but the car sounded really good has for the metal in the pan the pan has never been off the car and for the injectors in the car here's the numbers 621038 they do have a red ring around them and for the chip hes going to answer that one.

Dan told me how the oil pressure on his fresh stage two motor is and my car is about the same hot idle the oil pressure is about 10-15 psi and at cruising speed depending on rpm it goes from 30-40 psi. As for the injector chip combo I just believed that the last owner was smart enough to match the chip to the injectors. I'm glad the engine is fine but I must have OCD or some real bad case of a love for my Buick I hate that little thud thud thud the car makes but if the engines good to go I'll just stop worrying.
To a new owner its pretty easy to get paranoid from time to time.
 
Thanks for the help Dan          Also the chip is a Turbo Tweak but who knows what its for... its a 5.7TT

Looks like a lucas part number but they don't list a 038...got me

[Steve Wood]

Unfortunately, a stage engine is built to much larger clearances than a stock block or it should be.  As we don't know anything about your engine, it is hard to know....I would have expected 25 psi on a stock built engine on 10-30 but who knows on yours?

If you have time, go double check a couple of injector numbers again to see if 621038 is correct....the 8 looks wrong to me from the lists I can find, but there are a jillion injectors out there.  It sounds right, I just cannot find it

Sorry some built up dirt made the last digit look like a 8  the real number is [ 621030]

Dan is right...those injectors used to be called 40 lb injectors but these days they are called either 37 lb or 38 lb injectors but they often flow 36 lbs/hr when flow tested on a bench at 43.5 psi of pressure.  So, basically they are close to what we used to call blue stripes which was an Bosch injector where these were made by Lucas.

They were one of the early injectors we used to use and they worked okay but they have a pencil stream flow rather than a wide spray pattern so technically they are not as good.

I don't think Eric ever made a chip for this injector but probably used whatever was closest in actual flow curves.  Maybe his 42 lb bosch chip?  I don't remember and you would have to ask him.

If you set the fuel pressure to give you about 780-790 on a hot engine (not one that has come up to temp idling, but one that has been driven and then brought down to idle for a moment) and then set the wide open throttle  fueling to give you about the same O2s at the top of third gear, I suspect it will work, but again, you can ask Eric.

Given you don't know how well they are working, I would probably buy a modern set of injectors and a matching chip as it will cost you about $100 to have those cleaned and tested.

That's the plan my man ! I'm going to order from Turbo Tweak some 60lb injectors with a matching chip. http://www.turbotweakstore.com/ProductDetails.asp?ProductCode=1016
I'm guessing the link I provided is the most popular choice amongst the turbo Buick guys now? I also plan to get a new Fuel pump as well as a brand new hotwire kit .. I want to pull all the old shit out and make sure its done right.. I don't trust the old wiring. Could you link me or send me in the right direction as far as fuel pumps go?   

[Steve Wood]

I would just buy a pump from Racetronix up there along with his hot wire kit and his new intank wiring harness.  Most of these cars have deteriorating wiring harnesses in the tank from the pump to the bulkhead connector on the sending unit and they cause problems eventually.  Also, the factory pump ground wire is not very well done and the Racetronix intank harness does it right.

The 60 lb/hr injectors are about as perfect as you can get

Yea time for a upgrade... cant wait to see how she goes after I get that new chip and injector combo !

[Steve Wood]

May not be a lot of difference, but it will sort out any issues with bad injectors and such.  Injector size only assures that you will have enuf fuel to meet the horsepower requirement.  Clean ones with a matching chip will improve drivability problems if any exist.

The first thing you have to do is to eliminate all basic problems that may exist.  Whether it is fuel delivery related, bad wires, plugs, coil pack, module, cam sensor, crank sensor,  turbo that is worn out, oil in the intercooler, vacuum leaks, slipping tranny, etc., everything has to work right.

There is nothing magic about these cars and they are actually a lot simpler than new cars, but, so many people don't understand that everything has to be right before the car will run as it should.

It is seldom an overnight project unless one buys a car from someone that understood the cars and kept everything working right.

[YGspider]

Yes, I've already changed the plugs, cleaned the intercooler and almost all other spring cleaning items, New cat , fuel filter , I've rewired and got better grounds for everything. The only thing I didn't touch was the hotwire and injectors because I believed the owner had them setup.
I might get a new coil pack down the road from Highway stars the updated one just to be sure but I'm on the fence as mine seems to work good. As for the crank sensor and cam sensor I don't know to much about that but the car seems to start and run fine? 

[Steve Wood]

There is no magic in coil packs...they all work the same with regard to results

Just buy a good pump and a PnP hotwire kit from Jack at Racetronix, cheap insurance and peace of mind will follow.
