gen 3 rx7 injector size

Post by screech »

anyone know what size the gen 3 rx7 (92-99) injectors are? are they 850cc or more like 550cc?

They've got two injectors per inlet port. Try asking Si Cook on the IMOC-UK YahooGroups List - he's got a 1995 R (s?) model.

I believe the secondary rx7 injectors are 850's side feed. This is what I am running in mine.

Yup Paul is right, could be a decent and cheap source of injectors but trying to find used ones kicking around is nigh on impossible without some serious hawking.

problem is you can only get them in sets of 3 second hand as thats all they had i think.

There hard to come by.

i read about suppliers having to order 12 at a time to make up 3 sets. This is 4 sets of rx7 injectors tho.

2x 550's, 2x850's

The reason for the packaging maybe down to the jap market with many having triple rotors in them !

Brilliant engine, so small yet so powerful, but very thirsty about it too and designed to use oil !

People whom often upgrade, keep their 850's for the primary injectors and start using 1200cc's for their secondary supply.

Hes doing the whole lot ! I think the injectors he gone for are 1600cc ! :o

The turbo he's gone for is 0.70 a/r on the compressor, its all external gate, manifolds, large FMIC, suspension ... again... damn, if you saw the way it shifted before at only running 11 psi !! lol !! it was fantastically quick !
