What # injectors should I be using for a 350? Does anyone know what the color code or the part # is for these injectors?

Thanks guys,
Mike

I read on another post that the 350 pick up is 55# orange/black and the 350 cop car is 65# yellow/brown. But when I talked to Turbo city they said the 350 caprice was 61# and the 350 cop car was 68#. So as usual, old bob here is confused. Anyone know for sure? It would be nice to get some part numbers too.......bob

By the way, burntblues, did you get the GM cop chip for your 350 or a custom chip??

dont put much faith into what turbo city tells you those guys arent too sharp

 

i would agree with pablo, everytime ive talked to them, i think they were just screwin with me and transfering me to their mail room or something. NOBODY had any answers.

HOWEVER,I do have turbo city flow matched injectors that i bought from the classifieds here. they have yellow on them. and they are labeled 68#ers.

so i agree they arent very helpful, but they might be right in this case.

ONCE AGAIN I CALL FOR SOMEBODY MAKING A TABLE OF INJECTORS PN'S AND COLOR CODES.

Pable and Snflu,thanks for the heads up on turbo city.When I talked to them they seemed less than interested in my questions. I was going to have them bore my TBI and put in a set of matched injectors.
( I have read how you can do this your self but it is beyond my time and tech ability)
Do you guys think they do good work or will they screw up my TBI? I also talked to TPIS
who also does TBI work. If you weren't going to do it yourself and you were going to bore the stock TBI who would you use?
Thanks as always.......bob

I asked for that table, too, Snuf, but to no avail.


Snuf: any 2" unit info, yet?

In my sig it says that I am using the caprice chip, but I'm not sure if I actually am or not, the guy at hypertech gave me a chip # that said that it would fit, and he said that it was the 350 caprice cop chip. When I got down here to NC, they couldn't locate it in their database. Can you guys give me the caprice chip #?

You'll have to cross reference the chip somehow. Probably need a very friendly Dealer to help you but it would take up their time and they would get no moneys o thaty probably won't help.

 

burnblues, sorry not to get your post answered on the 23rd, but here is the information that I have. 1989 Caprice "cop" 350 TBI- service # 1228746 on computer. Broadcast code on chip is ANLU. There are also two other numbers on the decal that are 86ANLU K391310047 and 16125841. I do not know what these last two are. I also have a 1990 Caprice cop car that I could get numbers from if any one wants them. I hope this helps!

 

fastbroker -- nope, havent even been there for a week.

anyway, turbo city most likely does good work, and im sure tpis does too. they are technical people who probably get the same calls everyday and just arent very friendly. I think that you should go with tpis if you feel like rewarding friendly service.

if it were, me, id choose the cheapest. since i think that both are going to do equally good craftsmaship. if they cost the same, go with the more helpful nicer guys.

thats just my opinion.

 

DM91rs, do you know the cam Specs, compression and injector sizes or injector "colors"
on the 89 cop engine?? Its a lot to ask I know, but I am doing the same swap as Burntblues (92/93 350 caprice)TBI. I found the Cop chip (16220837)
for the 92/93 LO5 engine but it may or may not work in in a 91 camaro with a
1228746 ECM.
If the 89 Cop 350 is similar to the 92/93 version, ie cam, and injectors, than the 89 chip might work well for this swap since the ECM is the same. Any of the above info you or anyone else has on the 89 Cop 350 would be greatly appreciated.Just getting the Chip number for that car was awesome!!!
Thank you very much.....bob


Snflu, thanks for the input on Turbo city and
TPIS. Good advice.....bob

Thanks for the info on the chip # DM91! I'm going to check that out later today to make sure that I have the right one.

So what did we decide were the color codes for the cop injectors?

Thanks, Mike!

yellow/brown are the cop car injectors


as for a chart with part numbers, that would be a little bit of a task seeing as how for one specific injector color code there might be 10 differnt part numbers

 

RSilver, I beleive that Pablo is correct in the color code for the injectors and that they are 65lb units. My info on the compression for the L05 is around 9.6:1, the cam is at .050 194int. and 202exh. lift 385int and 403exh. The chips that I have used so far have all interchanged. With the same 746 unit I have use the 89 stock chip(auto} 89 Hyperteck stage 2 chip 5 speed 89 lo5 chip auto and the 91 stock chip 5 speed. When using a 5 speed chip in an auto car you need to rewire the 4th gear lockup switch because the 5 speed chip will not work the torque converter lock up. Good luck and I hope this helps! By the way Pablo is correct in stating that the best chip for a modified eng. is a custom burnt one. The before mentioned chips are at best a temporary fix untill you can tune with a burner.

 

DM91RS, man, what a help that is. Sounds like the 89 LO5 is basically the same as the 92/93 LO5, so with your cop car chip# and the 65# injectors I should be off to a good start. Thank you very much..........bob

Pablo, I had no idea there were multiple part numbers for the same size injector.I now know the color codes, so will just use them.
thanks for clearing it up.......bob

tomorow im finally going to get down to my parents dealership, and will look up all the numbers on the computer, ask the parts manager for info as well as check out prices.
it will be my good deed for the year.

 

so about burning a custom chip...

I've been told that it isn't that difficult, but i'm kind of lost on the whole deal and I'm really not that into getting all of the equipment to burn one chip. In a couple of years, when I get out of school, I will probably carb out the engine. I don't suppose that anyone who knows how to burn a chip would burn one for me if I paid them? I really don't want to pay as much as superchips charges...

thanks, Mike

that would be really cool snflupigus. Maybe we could all work together and get some of these questions over with while adding a new article to the tech section. This is a pretty common mod!

Hey DM91,

The chip number that you gave us (16125841). What is the chip number from the 1990 caprice car. What is the transmission setup on the 89 or 90? My car has an auto with the overdrive, and I would prefer to get something close to that. Also, I heard that tire height is also important. Does anyone know what the cam specs are, and if having a mild cam will affect the performance of the chip? My cam is 214-intake 224-exhaust. TO CRAZY, OR GOOD ENOUGH?

thanks everyone!!

Snuffy, your good deed was to get me a 2", I thought??? I'll even take a Holley (blahhhhhhh) unit now because I do not need the injectors/pod. Just gonna use it as the air inlet TBI/TPS to make my own MPFI system with Rich at Cruzin Performance. Gonna use the TBI ECU, though.

Now I need any used 2" TBI unit, OEM OR Holley garbage, and injector/pod funtion/existance is of no matter to me.

 

factory ones from a dealarship are way more than you want to pay, even at cost. which i found i would not be able to sell for anyway.

i am designing one, and hope to be able to manufacture/sell it within the next 6 months. I just got a giant helping hand from a professor who has givin me availablity of a very new high tech, 3d modeling software at school. I will also be able to work with her in having it machined too.

 

The trans in the caprices are all 700-r4 auto's and the cam's are very mild torque grinds of 194 to 204 durations at .050. The larger duration cams will require a chip reburn from what I understand. I will try to get the info on the 90 model chip by Thurs.

 

What # injectors would you recommend for a 305 TBI??? I have the stock injectors now, what would happen if I put bigger ones in??

------------------
Godti
'89 Trans Am (Red)
305 TBI 5spd

 

Godti you would run rich, your car would eat lots of gas, and it would be slower


injector changes are only neccessary when you have seriously modified your engine, and even then, you need a custom chip to adjust for all of the changes (including larger injectors)

 

pablo, If I keep my 305, would boring out my stock TBI (expensive, I know)and keeping the stock injectors help? It seems i would get similar benefits to your holly 2" set up.

boring a stock tbi isnt expensive
youll need to bore the manifold too or get a new manifold
you need to get air out of the motor before you get air in though
