what injectors

[cozzylee]

im going to be going upto stage 3 soon and am looking for around 350bhp which injectors would be best 403's or 803's

[Bosch Man]

i'd go 403s or 400's even better...loads of off the shelf maps about350bhp is maxing the 803 really.

[cozzylee]

thats the way i shall go then mate cheers

Either 803s or 400s are fit for 350bhp. The 400s give you a margin if you want to go for a little more power later, but anything over 350bhp with the 803s is pushing them above 80% duty cycle, which is obviously not ideal, as you have very little safety margin. 350bhp doesn't warrant 403s IMO, unless you intend to run over 400bhp at a later date.

[cozzylee]

so the 400s will be good if i want to push for 380bhp

[cozzylee]

am i right in guessing the 400s are the light blues and the escos comes standerd with dark blues

Correct . The 400s also have a much nicer spray pattern than the 403s .

does £60 sound a good price for a set of used light blue 400 injectors

I sold my 803's for £100 so yes, a very good price

Very good, are they proper 400's? Check if they have the fitting kit, as std they wont fit the YB.

What exactly is the fitting kit Phil? I hear people talk about it all the time especially with Greys...

[Kelv]

its because the injector nozzles are a slightly slimmer design, they need a larger rubber O ring to ensure a snug and perfect fit.

Lee, if they are genuine then it is a good deal, but definatley get them off to Phil for an overhaul and clean before you use them.

I had 414bhp on my old engine running a T34 and light blues
