New Question - SAAB Red 346cc Injectors


Recommended Posts

ok seems from a little research they are 470cc @ 3Bar injectors, and they are standard Vauxhall VXR injectors.

This is another set - http://www.ebay.co.uk/itm/Astra-VXR-Bosch-470CC-Injectors-Z20LEH-Z20LET-C20LET-/110716646617?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item19c739f4d9#ht_680wt_1139

Note it states in this one...

"Also suitable for the following Vauxhall engines C20LET, Z20LET, Z20LEL & Z20LER"

As the red-top injectors are from a C20LET I would assume they will fit?

NEW QUESTION - RE Saab Injectors

Are the Saab Turbo injectors any good? They are 150 series so will fit. They are easy to get hold of and they are dirt cheap!

The Bosch Number is 0280150431

And the flow rate is 346 @ 3Bar,

What kind of power will these start topping out do you think?

Any Help Appreciated.

id say go for known 440 or 630 injectors , as although they tend to be a bit more expensive , they are better supported if you are going to use a out of the box solution ( united motorsport )

you can of course run smaller injectors @4bar instead of 3 , but you run the risk of pushing them hard ..

my two pence .

Completely agree Jim. Many injectors are designed for multivalve heads and won't work that great in a 2 valve VR6 head, which is why sticking to the tried and testeds is best.

I used the Saab ones in an attempt to get better idle quality which is often what you lose with big injectors, but the 150 series are ancient now and my 500cc Densos idle better than the stock pea shooters!! They weren't cheap tho :-(
