Originally posted by Zoomspeed What classifys as an aftermarkey fuel system? 1. In the diagram, I show nothing for the fuel pressure regulator. I did some fuel system work at the same time as the vacuum system which included an aftermarket fuel pressure regulator that I attached to the nipple on the bottom of the lower intake manifold (same source location as stock but with only one hose.) You MUST leave the stock system intact OR add an aftermarket pressure regulator of some kind. For those not modifying their fuel system at this time, be SURE to have the FPR solenoid and lines attached well and correctly (failure of any of these parts could easily cause engine failure).

jonski,
seems like you didnt put any resistors or solenoids for resistance. arent you getting a limp mode response? Nathan |
So how hard is this? I'm so affraid to jump into the vac lines.
|
be afraid, be very afraid :D
I jumped into it without any thought and it's a bit more work thank I would have like to do...But what the hey, it's just as good a time as any...I am sure my car will be off the road for another 2-3weeks.. No emissions here in Oklahoma Rodski :D |

So how long should I expect to take doing this? I'm slooooow.
|
What kind of power gains can a guy expect from the simplification? I going to do mine this weekend and caught this thread... lucky me. I was going to do the regular replacment but I like the sounds of htis setup. :D
|
whats the difference between the normal vac line job and the simplification job? obviously it makes it easier, and i guess cuts the number of vac lines down...but what do you do with the lines that you dont replace? just plug up the holes, or what?
|
Just wondering, how does this effect or gas mileage? I get 12 MPG, crappy, but willing to put up with with it for this car. After the simplification does the gas mileage get worse? by alot?
|
I couldn't tell you for sure, but I don't think it has a huge impact, if any. The simplification simply removes the emissions controls and the double throttle. The turbo system itself remains completely unchanged.
|
this eliminaates the EGR system correct? doesn't that ahve an impact on the gas mileage? or is it a negligable difference?
|
without porting my wastegate, could this get rid of the boost creep that i am getting in the upper range?

Zoomspeed,
The new EGR gaskets block off the EGR anyway. The EGR is only active at cruising and highway speeds, so if there is a difference, then you will see it there. suprfast, I doubt that the simplification will prevent boost creep. In my opinion, the name "turbo simplification" is a misnomer. In the simplification, all hoses and connections to turbo controlling parts are the same as the complete diagram. Besides, boost creep is caused by a wastegate that is either too small or not opening up all the way. A restrictor plate should help you prevent boost creep while you are waiting to port or fix your wastegate. |
I just finished re-installing the solenoid rack after replacing all hoses and just realized I replaced all the small hoses with 6mm not 4mm. I got the kit from hosetechiques. The 6mm does fit nice and tight and I tie wrapped every connection. Seems the only difference between the 2 sizes is wall thickness and yeah ID is smaller but both sizes have to stretch over the pipe/ solenoid nipples. So at this point the car has been down for over a month. I'm at the screwit point and will continue reassy. So will the 6mm with thinner wall hold stock boost pressure?
Thanks. |
my gas mileage is still bad.
i think gas mileage affected by various sensors that the computer decipher on how much gas to put. For some reason the sensors think the car is lean, so it dumps more gas into it. replacing the O2 sensor will help, I think. Reza |
