My stock GN is being transformed. In the works is the following upgrades:
TE44 turbo
3" down pipe with dual 2 1/2" exh
K&N cold air
adjustable regulator
larger pumper

-Interested in going in the low-mid 11's.
-Should I go with 42# or 50#?
-Which fuel pump?
-Intercooler? -front mount, stretched or a modify my original w/Duttweiler necks? :confused:

- Injectors: For mid 11s (i.e. 11.50s) Either injectors should be OK if the car is tuned properly. The 50s would give more leeway. If you want low 11s. (i.e. knocking on 10s door) the 50s will be barely adequate. Might want to step up to 55s, or 60s. The MotoTron high-impedence 60s don't require any ECM mods.

- Fuel pump: Walbro 340 or Red Armstrong XP. Beyond mid 11's you'll want a dual intank setup or to go external. Hot wire feed either way.

- Intercooler: That's a seperate discussion area, of course. You'll need something beyond the OEM one with a neck, IMHO. Front mount for deep 11s is my suggestion. For mid 11s, its a tossup. To dig into that deeper, please discuss on the appropriate area of this forum.

Chances are very good that you will need a larger turbo to accomplish this.
