Project 1999 OBS GMC / whipple lq4 / FLT 4l65
Hey guys, I just picked up a super clean loaded 1999 obs extended cab with tons of options for $600. I needed a reliable work truck that made some decent power so I scored a 6.0 lq4 with a whipple on it at a local yard.
To back it up I ordered a FLT stage 7 4l65e and a yank 2800-3000 stall converter which will adapt the stock flexplate to my LT style trans. (Wanted it all to bolt up as simple as possible.) The wiring and adapters are all coming from street and performance. I'm keeping the AC they are using a bracket for the bottom end of the engine instead of the usual up top one. I grabbed a set of the multitec injectors from srt10killer so I can eliminate the crappy whipple electronics. Also plan on bypassing the blow off valve. The blown 5.7 vortec and 4l60e is almost all the way out of the truck now. Rain and waiting for parts will keep me a couple weeks away from finishing. The goal is to be finished by the end of July. Seems impossible but I have a lot of faith that it will work. - Edit - August is here and im only a couple weeks from being done. Not bad haha Once its all in I will have slowhawk dyno in bridgewater ma tune out my errors on the obs computer (for emissions inspection) and then have the nbs computer tuned for the bigger injectors and boost. Comments and questions welcome, I will have a lot to ask as I finish but I might as well start the build thread now. Pictures soon! |

nelson called and said he could build me a simpler harness for less money... but i doubt... ive heard some negative things about them, what do you think?
help me find a quiet (does not wake neighbors or attract police) high flow muffler that will drop in the stock location... maybe borla? what size is the factory piping? 3"? |
Nelson's harness probably will be fine. just don't let him tune your shit.
oh and i wouldn't mind cruising out and helping you too. i can turn bolts, just tell me which bolts to turn. haha |
