Not a whole lot, a timing bump will creat way more press than the injectors will. you should be fine with a 75 hp injector.

What are your plans for the 92?

well my goal is about 475 525ish with bigger turbo set up just not sure how much fuel that ve pump will push. the getrag will hold up to the hp just going to need better clutch set up. twins may be possible but is is going to take some time. i got the truck 12 years ago bone stock. all i have done is some 50hp injectors a fuel pin and cranked up the full fuel screw on the back. need to do the gov. spring on it. but when you are juggleing two trucks the money is not always there
