I've got Accel 24 lb injectors with about 8000 miles on them, if you want. I'd definatly be getting a new pump, if I were you.

Backpressure is a myth and turbo cars work best with the most minimal of restirctions for the exhaust. If you understand how turbochargers work the turbine wheel creates all the "backpressure" your motor could need.

If turbos work best with little restrictions (which I do agree with), how is backpressure a myth? Exhaust restrictions create backpressure, I don't think that is up for debate.

Now coming from a standpoint a little offset from what you guys know(cuz I don't know ****) run the big pipe aftet the turbo. Exhaust is a hot and expanding gas, So 2.25" to 2.5" before the 3" outlet after the turbo *SHOULD* give you proper VELOCITY(ignore backpressure, velocity is key), for spool etc. So call backpressure a myth, what it boils down to is air velocity. If exhaust is an high velocity heated expnanding gas, you want velocity to remove it from the system(same application applies to turbos.) You have the so called "back pressure", or velocity. velocity on the tail end of an air pump with a turbo translates into velocity and pressure on the front end of an air pump. You do not want to over exceed the displacement of exhaust gas past the turbo as you will reach a point where the exhuast gas will have expanded and slow down, restricting evacuation of the gasses ahead of it. And by all means, if I am wrong on any of this, please specify and correct it for me!

J wikoff how do those injectors work for you? i know im probally going to have to buy them before i start this project and i still need to know a good electric oil pump. i was told a shurflo 8000 is good and i can order one online for about 45$ so then im down to injectors and installation.

They worked fine, other than being too small for my application, which I found out later. Your stock injectors are 21 lb, if what I've read is correct. Stock L67 injectors are 30 or 31. These are 24. I do suggest you find out what you do actually need, though. And remember, I strongly suggest you get a new fuel pump for a mod like this. You don't want to go lean. At least get your pressure tested.

j wikoff would your injectors work with if i ran them with a turbo or would i need bigger injectors than that? also can anyone recomend another fuel pump since ill probally have to change it sooner or later. im ordering the oil pump so that leaves me with just the injectors and fuel pump to worry about and then the cost of installation to worry about too.

I can't say with certainty if the 24 lbs will be big enough for you, honestly. If you are only going 5 lbs of boost, they might be.

As for fuel pumps, look for a stock 92 L67 pump or a Walbro 255 LPH unit. Those are my 2 suggestions. I don't know a part number for the Walbro. Willwren has one in his 93.

could i go with the #30 injectors from seriesoneperformance and the 255 fuel pump from them?

24# will support 215 hp @ 85% duty in a */c application. The stock PCM or ECM should be able to run them. 30# injectors would be fine but will need programming to run them properly.The 190 litre Walbro pump should be plenty for your application, and it has a lower current draw if you use the stock wiring. In any case you will want to run a scantool while tuning this combination.
