Fuel Injectors 450 Chimaera

[S4CJO]

Having had an issue which may be injector related, looking to change the current.

Where would be the best place to get a set? Is there an upgrade to the std set? Has anyone used Mr Injector mrinjectoruk.co.uk?

If you upgrade (as in fitting larger injectors) you will need to remap, plus the stock ones are good for over 300 bhp before you run out of injector opening time.

had my injectors serviced by injectortune, six years and a few thousand miles ago, still running well

Another vote for injectortune - quick turn around and easy to deal with

I bought eight new ones as three of mine were dead, not fixable?apparently.

It was going to cost 25 quid plus vat to clean the five good ones (assuming they were) new ones 47 quid.ish including vat.

Genuine standard lucas, cheapest from , would you believe, tvrparts !

One got a set in the garage, upgraded when turbo was fitted but were at full capacity so went up again.
As good as new if your interested.

What sort of problems were you having?

[ClassiChimi]

I've never tried on the Tvr but is it possible to feel each injector for a pulse when the engines running, if one doesn't click then it's either knackered or the electrics are fubbered id imagine.

[Chimp871]

Yes. You can use a stethoscope doctors thingy to listen to it.

A cheap and simple way so long as you are not deaf.

No problem they where at full capacity when I had it tuned 360 was their limit so had them swapped for larger capacity.

There is also the Vauxhall Vectra upgrade. I had these fitted on my old 4 .6. They have a better spray pattern.

Some time back we did some random money throwing at my engine to try and improve performance.
A 72mm plenum, 20 AM AFM, and Bosch Red Top injectors were installed.
The Bosch injectors have a better spray pattern I am told, and can handle well over 300 bhp.
It of course needed a remap.

Ditto. I need to put bigger ones in to get any more power.
