Injectors

[QBTO]

So the injectors have two seals at the fuel in side, but what seals them in the throttle bodies ?
Is there a seal internal in the throttle body ?
Do I need a dentists mirror and torch to see them ?

Hopefully this makes sense.

Good info Desert Fox,
I didn't realise that the seals were available separately.

Cheers,
Rick

remember to check this thread
the company services injectors fits new filters and supplies with a report and new seals .
all for £57 for all 4 injectors including return postage (you pay extra to send them)

standard suzuki injectors are £201 each plus seals are £15 each .

Some models of Mitsubishi Eclipse & Galant and Yamaha F 115&150 use the same INP-771(CDH 210) injector than 14.
You can find them from Ebay 30-50€/4pcs. New ones. With seals.

Found them on the net. Chinese made though.  Which doesn't need to mean that they are of low quality. Could very well be that the Suzuki branded ones come out of the same factory.

@T 24 or anyone else actually used the inexpensive ones?

[T 24]

I use those cheap chinese injectors on my N/A side (Suzukis own injection system) and 350cc Bosch injectors (Saab 93 turbo) on my "boost side".
Those CDH 210 injectors were flowing a bit more than old originals, so I had to adjust fuel pressure on N/A area a little bit lower.

Thank you for the info.

Opened up some questions and concerns. Have to think about it.

[T 24]

Those China made injectors are OK stuff if you are able to adjust your injection (wide band lambda + PC or adjustable regulator or both).
But if you just change the injectors and dont want to check what you did, keep in originals. IMO

Thank you for your advice @T 24

Since I don't have any of these, I'll follow your advice and stick to the original injectors.

Will get them originals cleaned after cleaning tank, Fuel filters, and hose.
