Injector size (cc) for single throttle body clio 172/182?

[graham_172]

Does anyone know the recommended size in cc for the injectors on the F4R lump if fitted with larger single throttle body. Would picco 330cc injectors be recommended or get a fuel pressure regulator and up the current psi?

many thanks

I heard standard are good upto 208ish bhp so id be happy to push them to about 200 without changing

Yeah, good up to 208 bhp so unless your in a very high state of tune running up to or over that or running TB's they'll be fine.

As for the larger TB size, seems to be split down the middle as to whether there's any performance gains to be had

when i did the original conversion it turned out to be a pretty pointless affair for power, only squeezed a few bhp over a stock car

was better to drive, but an expensive conversion (if using the ETCC jenvey body)

just buy the kit from r-sport, job done

what is the kit? how much?
