Supported Hardware for Stage 1+
Injectors must come from a reputable source. Bosch 550cc (0 280 158 117) is our preferred injector, it can be used with E85 and gives you room to upgrade. If you have injectors larger than 550cc, please email us and let us know what you have. We can typically accommodate them, but there is an upcharge depending on size and manufacturer. If you purchase 750cc and larger injectors through Motoza, the upcharge for injectors over 550cc on a Stage 1+ will be waived. Please note that narrowband ECUs are limited to 550cc or smaller injectors.
Bosch 386cc Audi TT injectors or Bosch Green Giant 440cc, and Siemens Deka 630cc are also options for pump gas. (We really don’t suggest Siemens 630cc; genuine Bosch 630cc are no longer imported into the US). Please see the Injector Policy section below.
If you have a turbo larger than a K03, please see our Hybrid K04 or Big Turbo options.
Intended for the stock MAF, but a 3″ housing with the stock sensor can be supported at this price level.
Diverter valve can be piston style, full recirculating or hybrid, but no BOVs. The Bosch 710N diverter valve is another good choice for Stage 1 and 1+.
No limitations on intercoolers, intakes, exhausts, or fuel pumps. For upgraded intakes, please use a dry filter. If using an oiled filter, regular MAF cleaning will be needed. Any exhaust may be used, but additional track car verification may be required for full support.
Upgraded rods and/or valvetrains are supported, though not at all necessary for stock turbo projects. Cams, upgraded throttle bodies, adjustable fuel pressure regulators, and alternative MAFs are not supported at this price point, but we are happy to quote you if you’ve upgraded them.
Injectors are the heart of your build. They need to be genuine Bosch or properly modified with a detailed flow report. Injectors must come from a reputable source, there are too many counterfeit and subpar rebuilds that do not flow as advertised, may damage your engine, they waste time and money and we will not support them. This site is, of course, a reputable source, but there are others and we will gladly share that list via email. It even includes other tuning companies; we’d rather you buy genuine injectors from another tuner than purchase cheap, ineffective, or knock-off injectors. Injectors purchased on auction and third party sites that ship in boxes with smiles on them are not worth your money & time. In short, if you are looking for places to save money on your project, injectors are not the place to do it.
We expect that cars will fuel differently based on age and condition, however, all of the injectors supported by the Stage 1+ have a normal range of variance. If your injectors are not within this range you may be required to replace them or flow test them at your expense.
