Im going to be fitting tb's to a 1.6 16v, I just wondered what fuel pressure regulator I should use. SBD reccomend a black top one at £85 + VAT, is there anything cheaper I can use that will be good enough?
power boost valve will work, but the reason SBD recommend a better version is because it more accurate and efficient and maintaining high fuel pressures.
IMO fse fuel pressure regulators are poo, weber do a verynice which is 3.5 bar and can be adjusted if you remove the dust cap, i use one and so does region17rc and he has a 200+bhp 1600 16v where accurate fuel pressure is crucial. I cant find the invoice at the moment so cant give the part number but its about 45 quid and is the 3.5 bar model. Its also very small and compact.
Do you have any more information on this guy who owns the 200bhp 1.6 16v Corsa? I only know of one in a corsa at the mo and would be interesting to compare his modifcations to that of the bloke i know.

i met andyh at a saxo vs corsa day, nice bloke, and his engines a stormer too! i've done pretty much the same as andy but hes had headworktoo so he maks about ten more horses than i do, heres themain spec
omega pistons
sbd group a cams and pulleys
waisted stem inlet valves
45mm jenvey throttle bodies with 90mm trumpets,cream injectors
dta engine management
lightened and balanced as a complete assembly with the crankshaft tuftrided for strength,
arp rod bots
spesso racing head gasket
anti pump lifters
cos the exhaust ones were all intact when i removed the head after the wtaer pump failed!! also dave at bat motorsport reckons theres no need, even with the inlet ones, the 16xe has 86% of the valve area of a 20xe as standard aparantly this is one of the reasons they can get big hp out of them i think
that was the problem with my fse type reg, i'm running 50 psi and after about a week it just couldnt hold the pressure, spotted n the rollers thankufully, the guy who mapped the car recomends the webber one because he has never had one fail and so far mine hasnt either, and a fifty quid i think thats a bargain!
I bought the SX fuel regulator from Earls Performance. Its a lot more expensive than the black top FSE regulator but with the amount of money spent on my engine I cant afford to have fuel pressure problems and need a reliable regulator.

I just spoke to the bloke I'm buying the tb's off and he said that he never uses an adjustable fpr because a small change could ruin your whole map. That he uses a fixed one so that if it goes wrong he could just change it and his map is unaffected.
What fuel pressure is generally used? He said either 2.5 or 3 bar...., and then to map it to suit.
I agree thats a fairly sound argument, but most people set their adjustables by plugging a guage into the fuel rail, thus you get a new adjustable and set it exactly the same. A fixed one will have a tolerance, and you won't be able to dial that out. So an adjustable will inherently be more accurate because you set it the same.
