View Full Version : Best injectors

06-05-2005, 04:15 PM
I am looking to upgrade my fuel system on my 87 GN to get me to mid to low 12's and I was just wondering what injectors you guys suggest (i.e. brand and flow rate). I will probably run it with the walbro 340 keller was talking about with the hotwire kit. Any suggestion would be great. Thanks

What turbo do you have? (or are you planning to have)

I have Bosch 36 lb/hr "blue top" injectors and I've dipped into the high 11's. Run 12.0 routinely. Should not need much more more injector with a TA49 and your time target.

The 60s are easy to program for and are something with plenty of headroom.

You give up nothing with them ... good idle quality and linearity.

I wouldn't go with anything less than the 36# injectors ...

I am running the stock turbo and plan on running it for a little while longer because I am still in school and need to save the expensive stuff for a little later. Also, whats the differance between the walbro 340 and the walbro 255? Thanks

I think the numbers you meant are Walbro 307 and 340.

See http://www.gnttype.org/techarea/fuelsystem/walbroflow.html

Basically, less current draw and more flow at higher pressures.
