Is that not the simplified non-sequential mod?

Robinette site is great for info

I have just had a go at replacing some of the hoses in my rats nest, be very careful when putting the hoses off some of the plastic nipples on the solenoids as some are very brittle and where the hoses have gone hard they are very hard to pull off, twist them first to break the seal then should come off easier

Before you go ahead and start fiddling under there, what is it you actually want to achieve? Are you wanting to make your turbo\'s run non-sequential (i.e. both turbos spool together rather than one coming in before the other)? Or do you just want to remove the air pump, double throttle, AWS solenoids?

That diagram above also has no vacuum line to the fuel pressure regulator, so I assume its for people who have installed an aftermarket FPR.

i like to keep the twins as they are and i want to remove the air pump, double throttle but what is the aws solenoids as for the FPR would a apexi pfc have it bilt in?

Ok mate, you need to do quite a bit more reading before you remove anything I think! Don\'t go removing stuff for the sake of it.

Apexi PowerFC is a ECU, it\'s a computer. A Fuel Pressure Regulator (FPR) is a mechanical device that controls fuel pressure in reponse to vacuum/boost conditions, so no, the Apexi does not have one built in.

That diagram above is for sequential twins but as Aubec pointed out the hose to the fuel pressure regulator is missing in the pic so you would need to replace the old hose. AWS is only fitted on UK cars so if its a import your car won\'t have it.
You can only do the simplified rats nest if you have got rid of the airpump and the cat, and really an ECU such as a PFC.

started it today taking my time but still manage to brake a solenoid lol im getting scared now so im going to have a brake any pointers will be handy.

philiwily · April 03, 2010, 06:35:04 PM

I found they broke unless I heated the hose with a lighter first.

Aubec · April 03, 2010, 06:37:52 PM

Which one did you break? I have three that I removed when I was doing mine, all three are intact and work fine

brundish24 · April 03, 2010, 09:31:21 PM

it the turbo control solenoid its got the spiny thing on it.

brundish24 · April 08, 2010, 05:35:00 PM

help needed as im not sure on what to do in the pic where the pressure chamber is near the lim the hose that has the check valve connecting to the lim now out of the four pipe comming out of the lim witch one is the egr as i only have three pipes comming out of my lim do i need the pressure chamber or not???
