KO Racing Bored Factory Rail 8mm
KORacing Products » Toyota MR2 MK2 » Fueling & Injection
The factory rail has a problem distributing flow to all of the injectors evenly, and this is exacerbated by installing higher than stock flowing side feed injectors. KO Racing can modify your stock rail to increase the bore from 4.5mm to 8mm! This provides much better flow distribution to your injectors at a very competitive price.

This modification requires the use of a stock rail -- we will need your rail to avoid a core charge. If you do not have a stock rail to send, we will require you pay for the rail we modify at $150 per rail.

Send your rail to the address shown here: Contact Us.
