Exclamation Transmision Rebiuld

hey guys im really serious i need to find somewhere to rebuild a transmision/transfer case. . . i need to get price quotes so i know how much it will cost and start planning for it. . . so if you guys would help me out i would appreciate it

i also need a motor rebuild and i would like to get it set up for some serious power while at it. . . i want to run twin turbos. . . can i run the injectors for twin turbos while running a stock turbo??? the motor rebuild isnt absolutely needed but my fuel pressure regulator is on the fritz and it will cost a lot just to replace that and from what im told you got to tear into the motor quite aways to replace it.

i also should look into the rear and front diferentials and drive shaft setup ( i smoke u joints like crazy)

im serious my truck needs a lil TLC asap. she is still reliable but i want her to be top notch again

well replacing your fuel pressure regulator isnt all too bad, your truck is a lly so it will be very simmilar so the same job on my lb7

if you want to build your motor better break out the plastic, it wont be cheap at all.

you can run bigger injectors with stock turbo it just depends on the tuning. a good twin turbo kit is the MPI system, you can keep the stock turbo and it bolts right on. it should come with a wastegate so it will be very hard to overspeed the stock turbo. a really good guy a tuning twins is idaho rob. his stock motor lbz runs 11's and tuned a stock motor lb7 to almost a 10 sec 1/4 at some ridiculous eveation, most likely would have been a 10 second pass at sea level.

twinning your truck will turn it into a towing beat, egts will drop a ton and you can run alot of power and not have to back it down due to egts.

a set of good injectors will help you out big time, turbo if you want twins you can build your own or get a MPI set and get idaho rob to tune it with efi live.

if you want to build the motor you can run crower rods, key your cam and crank, delip and coat the pistons and port the heads and upgrade the valve springs and cam.
