I'll have to speak with AndyF about the best approach i guess.

I already have a FP guage. I'd posted in GT about a FPR a while back, but never got a response to the fitting prices.

Are these roughly right?

- Injectors £350, fitting £300
- FPR £200, fitting £??

Just out of curiosity I'm running water / methanol injection from a 12 litre Spec C tank in the boot of my Bugeye sorted by Matt and Olly at RCMS :)

TD05 Deadbolt 18G with a few mods at 400 ish BHP and 2 wrecked newage 5 speed gearboxes :)

Now on a Jap 6 speed gearbox and just wondering what will break next LOL

What are you running with your water and meth injection ?

Cheers

Shaun,
the car is standard gearbox, engine so for me a risk there.
The VF34 and STI pinks are the limiting factor's if and when I want more:)
Zen did the work on the W/M injection:thumb: and like you I sourced the spec c tank for the boot ( the system is progressive and doesn't use as much as I expected, which probably reflects my style of driving). Paul advanced the ignition which increased power but also improved spool-up by approx 500rpm.
I use 50% meth/deionised water to reduce risk of blockages etc.
The temptation I'm now trying to resist is to fit one of Harvey Smiths 20grm,-time will tell.
cheers
Trevor
The saving factor for me is my driving style

I got my used STI pinks fitted by a mechanic I knew for £120. Other prices I got (non-specialist) were around £200.
Specialist would be nearer £300 but if they were supplying parts the all in price might not be that different.
cheers

IMO the FPR was one of the easiest things to fit that I've ever fitted, so probably not that expensive to fit :)

Or have a go yourself, all you need is the FPR and a bit of fuel hose (which is safe for fuel injected engines) :)
