Looking for 6 standard 550's from a 20B please.

PM me with what you have.

Cheers

You want the three primary side feeds and the three secondary top feeds?

If so, they are the same part numbers as...
side feed 550's come off FD primaries
top feed 550's come off Kouki FC turbo, either primary or secondary

The side feeds are abundant, but the Kouki FC turbo fuel injectors might be hard to find...

Cheers Ted,

My mistake, I though they were all side feeds.

I'm looking for 6 primary side feeds

93rx7

Ted, does that mean you've got loads you can sell me?

I've got 6 from my 20B that I don't need anymore. Interested?

93rx7

Yes, I'll take them Jeff thanks

Sent you a PM

I wish I had extras, but those side feed 550's are gold for the SR20 guys so they are hard to hold onto.&nbsp I don't think you're willing to pay $100 per injector for them.

Was looking to buy some used ones for around $30 each depending on condition and milage.
Can buy them new for $125 from RX7 store.

I've got a bunch of FD 550 side feed injectors and a 20B secondary fuel rail with 3 of the longer type 550 side feed injectors.. $50 each to anyone who wants them...

93rx7

Dragon,

I'll take all your FD550 side feeds please as long as they are not damaged and in good working order

I've sent you a PM.

Cheers

I've still got my three primary 20B injectors (secondaries too). $50 each sounds fair. I'll take one out of the rail to look at the numbers tomorrow.

Here's a zoom into my avatar pic. I put a little masking tape on the rail ends to protect the injectors while I was doing some work on the engine. Now all the injectors are doing is just sitting there waiting to go to a good home.

This is probably the best pic I have of them. Oh, and now you'll understand what I meant by MMO and yoohoo.

Actually, I would like to see a zoom into Ted's avatar

The injector on the far left was replaced it looks like.

I just spent some time with a high quality phillips bit and carefully loosened all the phillips head screws because the screws on the middle and rear injector hold-down cap looked like someone used a funky screwdriver at some point to R&R the injector. The front injector screws looked normal. I'm assuming the front's never been replaced or serviced? I don't really know enough about injectors to be sure.

The numbers are on the other side of the cap on the far left injector. The bottom is also not anodized black like the other two. It's obviously been replaced at some point in the engine's life.

All three injectors are 195500-2240. Who here knows what CFM that is? Don't tell me it's only 240CFM. That wouldn't be enough for a 20B.

93rx7

Yeh can anyone confirm if there are differences in the 20B primaries against the FD primaries please?

They are supposed to be the same, but we have looked at each injectors part numbers on the side, and they are different

20B 550cc Primary = 195500-2240
FD 550cc Primary = 195500-2460

the fd's are purple also

That pic above looks a little washed out. They're actually a little darker purple. They look darker than the ones in your pic, 93rx7.

My 20B secondaries are 195500-2020 if I remember right.

93rx7

Been talking to someone offline and he thinks that the 20B 550cc primaries are almost the same as the FD 550cc primaries but the pintal cap on the 20B's is slightly longer than on the FD's.

Are the 20B primaries high impedance?

Could someone post up a pic please of a 20B 550cc primary out of the rail?

RETed

FD 550's are red and the FD 850's are purple?
Or am I getting them all mixed up!

i should have been clearer

the cosmo injectors are all red

the fd has purple primaries and orange secondaries

Hi Mike

Do you know any more about the 20B primaries?

Could I take a primary from a 20B and fit it directly into an FD primary rail?

I need to know if the FD primaries are the exact same as the 20B primaries?
The only difference I am aware of is the pintal ends on the 20B primaries are slightly longer than the pintle ends on the FD primaries.
Are the 20B primaries high impedance, the same as FD primaries which are around 12ohms?

Anyone got a spare few minutes to put a picture up of a 20B primary injector out of the rail?

i dont know anymore, mine have never been out of the rail. if you can see one is longer than the other thats prolly the difference

mike

I would like to know the difference between the FD primaries and secondaries (beside the capacity). Can you put FD secondaries into the primary rail and have them fit? If that is so, and they are the same as 20B primaries, it would solve a problem I have with needing bigger injectors all round.
To answer the previous question about impedance, yes, the 20B injectors are all in the 12ohms region.

Heres a pic of a 20B inj with measurement as an indication.
