If you need bigger injectors, depends on how big. The 30# Ford SVO's are popular and fairly inexpensive. You can find them used fairly frequently as well.

The ls6 injectors are a tiny bit larger, and should be easy to find a good set. I know I've tossed several sets.

the GM turbo injectors are really good. These were used in the Turbo Trans Am, and are used in the ASA race engines, and I ran them in World Challenge.

That sounds a lot better than throwing a ford product in my corvette!

you have a 98 so you have the biggest stock imjectors for a corvette already. Then you have a return style fuel system. I would just buy an adjustable fuel pressure regulator and bump it up to about 70 psi from 58. They will flow another 3# or so at 70. It suprisingly takes quite a bit to max out even the stock injectors on a 97-98.

^^ These are an excellent choice - but a bit pricey. They're the GTP Bosch injectors part# 0 280 155 868 (Bosch part #). They flow 39.89 lb/hr @ 58.02 Psi (4 Bar).
Product info is available from Bosch Motorsports pdf. - give me your email and I'll send you a copy.
Best reason for using these.....GM has derived the offset tables for these injectors as they are used in the ASA cars and World Challenge cars. These tables are important for proper tuning - especially idle and AFR.
fwiw.

Default Why Injectors

Based on your profile, I don't think that you will gain anything from upgraded injectors.

Are you planning upgrades in the future?
