3.5bar Fuel Pressure Regulator & S2 Crank Position Sensor

[V-man]

Hello all

Just building my 16vt but i'm still short of a few pieces.

I think i'll be running my S2 injectors on a 3.5 bar fuel pressure regulator. I think the regulators were fitted to some of the N/A engines. Has anyone got one? It has to fit my ABY fuel rail!!

Also, the G60 management i'll be using needs a crank position sender but my 1.8 16v block doesn't have a hole in it for a sensor!! So i'm going for a S2 position sensor and run it off a 36-1 trigger on the crank pulley Has anyone got an S2 position sensor?

Thank you!

The RS2 fuel pressure regulator has a range of 3.8 bar

Thanks chap! I'll have a look but i think they'll be quite hard to get hold of!! I'll look into it a bit further and see what other engines in the VAG range used.

Right then boys, i managed to get hold of the position sensor. And as i was stripping the inlet manifold, i found the fuel pressure reg on it had 4 bar stamped across it. EH? lol!

Would anyone know whether that's 4 bar with or without vaccum? Thanks boys

Yeh, thanks for your help boys! I've sussed it now

Hi man.

Take a look on some BMW engines.
They have orig. 3,5bar fuel pressure regulators using and they fit in the fuel rail from the VR6, TT, ABY, ADU engines.

Here is a local company that manufactures caps for FPRs to make the original ones adjustable. It's a good product.

Upper one is for the small regulators as in ABY ADU and the lower one is for the traditional bigger one as in 3B.

When it rain - it pours! Eh lads! lol! I though i was the only one reading this! LMAO!

Thanks for the replies though chaps.

I had a look at a N/A 20v Leon engine spec details the other day. I know for a fact the APG engine has 3 BAR stamped on the regulator, so i looked at the fuel pressure testing page and found that the pressure should be 2.5 BAR normally but with the vacuum pipe dis-connected it should rise to 3 BAR. So the figure stamped on the regulator is the maximum pressure it can give. So mine will give 3.5 BAR with the vacuum pipe connected - which is perfect.

I'm guessing they do that so on start-up the engine gets more fuel as a vacuum hasn't been created yet?

I've managed to hold hold of everything now, for my 16vt, but the turbo. I'm still not sure whether to go K24 or K26...
