Rebuilding our OEM Turbo Buick Injectors with the Help of Injector Experts
It’s been a little while since we’ve brought you an update on Project Wicked6, our ’87 Buick Grand National project, but the wait was will be well worth it. After tackling a few obvious appearance items that have been driving us crazy for quite some time, and have finally had an opportunity to focus on what’s under the hood.
For the most part, Wicked6 is entirely stock, save for a previously installed Racetronix fuel pump and hotwire harness, and a Kirban cold-air induction system. The car seems to run and drive quite well, but as far as we know, the GN has never had its factory fuel injectors removed. This made us wonder what kind of junk resided within them, and although there are plenty of fuel injector cleaners currently on the market we wanted to take a more direct approach in having them cleaned for increased flow characteristics.
Although there could be a relatively small power increase, we didn’t feel that the prospect of one or two injectors to be slightly clogged would cause a massive difference on a chassis dyno, so we elected to skip that step of the baseline process. However, after we pulled them from their rails, we gave our friend, Keith Brewer over Injector Experts a call.
Injector Experts is a down-home, one-man band that allows the customer to speak directly to the CEO, engineering department, sales and a general technician all at the same time! This is quite rare these days where you usually have to cut through a sales rep, a technichian who might know the answer, who ultimately might redirect you to an engineer (if there’s one available), who will possibly be answer your question at other companies. Keith at Injector Experts knows and does it all.
Despite the fact that 98% of his customers simply send their clogged injectors through UPS, FedEx or the United States Postal Service, we’re fortunate to be based close enough to visit him in person. Located in Rising Sun, Ohio, we made the trek to the small rural town and had Keith personally walk us through the process.
While we ultimately plan on upgrading our injectors when we install a larger turbo and make some significant modifications, we’re overly curious to see just how clogged our stock injectors are, as well as provide you, our readers, some insight on just what exactly is involved in rebuilding a fuel injector.
