Hello,
I am getting ready to put my 89 s5 rotary motor in my 87 rx7 and I was wondering My motor has a knight sports turbo on it. Will my factory injectors supply plenty of fuel. I was going to keep my stock fuel injectors for the primary fuel rail but should I run like 650cc or 750cc injectors for the secondary fuel rail. I am also using a haltech e8. And does any body know were I can get a stock fuel injector rebuild kit for my factory S5 turboII fuel injectors.

Thanks

 

Just saying knight sports turbo doesn't give much info on it. In general, the ones I've seen are similar to BNR T04b hybrids, so based on that your stock injectors/pump will not cut it. I wouldn't use anything short of 4x720cc injectors and a walbro/supra/cosmo 20b pump etc...

 

My knight sports turbo it is equal to a to4e turbo
