Which Beams in my Altezza & fuel pressure?

[hp_zim]

Hi guys, i need some clarification on which Beams motor i actually have in my 2000 model Altezza. From the Altezza forum im told i have the RS200 Z-edition model with the 154 kw Beams engine but just need clarification as ive been researching and now found that theres the redtop and black/grey top.

Here is the pic of the engine Imageshack - p1280205.jpg - Uploaded by hp_zim

Also does anyone know what the stock idle fuel pressure is on this engine?

Only the Altezza has the BlackTop BEAMS (stock), so yours is definetely a BlackTop

Thanks for that. Anyone know what the stock fuel pressure is at idle? Mine is currently reading 3.6 bar but the car doesnt seem to be performing well and we suspecting its the fuel pressure

3.6 bar = 52psi.

Stock should be 62 psi, or about 4.3 bar.

Just a question as the altezza is a little different than our cars how do you check the FPR at idle. Well on that note before I speak out of turn how do you check our cars FPR. (given you have a gauge connected) I know the general way of doing so on most fuel injected vehicles but is an MR2 different? I know the Altezzas have teh FPR in the tank so they read a little funnier.. with no vac line to remove...

The MR2 redtops single vvti have a return style system. Like many carsN so its checked like normal.

Only the Altezza/Blacktop/Dual VVTI is a returnless system where fuel psi is controlled by the ecu varying voltage to the fuel pump (iirc). So you just check pressure as the guage reads, no vac hose to remove or block off.

Thanks for all your input. In my case the fuel pressure is lower than stock and as mentioned its controlled by the ecu so how do i go about getting the fuel pressure back up to spec?

Speaking of fuel pressure, could anyone tell me how much should it be in the RedTop?
