why did you get a dsm bov when you could get the same one from an evo locally for cheap or free? or any number of other oem bovs.

**Turk** · 10-4-07, 19:38

Because I got it for free(pretty much) anyway, and it is allready welded onto a 2.5" pipe. If I said give me everything except the bov, the price would not have dropped.

Only thing that might delay my turbo setup (by one day max) is the cross member modding. I dont have any welding tools at my house, nor the experiance. I want to make it strong enough for it to pass an engineers certificate.

The shop that is doing my tuning, said that they will have a look at it when the car gets here, or otherwise there is a shop accross the road that will definately be able to do it and loves payments being made in the form of a case of beer.

talk to the engineer first and see what he will and wont accept, that will save you pain later in that if you do what he wants, he cant knock you back on it.

**Turk** · 10-7-07, 4:45

I would but I have no time. The guys who are modding it, deal with engineers all the time and I told them it was a worry, im sure they know what will pass or not.

Anyway, ive got 2 weeks till im boosted. Very excited.

Only thing im confused about is my FPR. It is a FMU/FPR in one which confuses the hell out of me. The fittings look like any fuel pressure regulator but if is a FMU/FPR in one will it raise the pressure 12:1 or 1:1 for boost. I asked the guy who gave it to me, still waiting response. Will have to see.

**fredio54** · 10-7-07, 10:36

if you have bought a rising rate regulator, instead of a 1:1 unit, then use your stock reg and send it back, or quickly swap it for a non rising rate from the same place.

having a non 1:1 will [fizzle] up your tune and make it really hard to get right.

using a rising rate is a way to make sure you dont go lean with no management, not when you have a full tuning system.

unless you have a massive pump, the stock regulator will be fine.

Yer I know. The FMU is adjustable as well, Can go from like 14:1 down to 6:1 at least and the owner doesnt know if it can go down to 1:1. If it can I will use it. There are 2 adjustable screws, 1 for the FMU and one for the FPR.

I dont have a massive pump but I was told that the stock one gets outlflowed very quickly.

**AusTerror** · 10-7-07, 19:46

Sounds exciting!

I can't wait to see it in action.

**Turk** · 10-7-07, 19:50

2 weeks from today. All I need still is fuel pump to go in, and an oil return line. And some spare electrical wire, solder and vaccum lines. And maybe a fuel pressure regulator

there is something i dont know because this post doesnt make any sense to me?

fmu ? arent they electronic?

if an fpr was 14:1 when you hit 4psi, your pump would stall and your lines would blow...

you only need an fpr, and a ms. nothing more.

**Turk** · 10-8-07, 3:47

That is what I was told from the seller.

I want to use the stock FPR, but I have heard it gets outflowed quickly. i have Megsquirt, so the Adjustable fpr is not needed seeing as ill be setting it to stock pressure. But that the stock fpr cant keep up with the flow for the return. Im posted in the 2nd gen FI section, waiting response, probably will have to wait until tommorow when americans wake up.

Oh and this definitely isnt electrical.

it has 2 ends for fuel, feed and return. One up top for vacuum. One screw up top for adjusting Fuel pressure, one screw on the side for adjusting the rising rate fuel pressure.

EDIT - Just checked msg, it goes from 12:1 to at least as low as 7:1.

bin it now before it costs you in tuning time...

if your pump outflows the stock regulator, you will soon know. the point of an adjustable fpr is not the adjustability, its the flow, IF you need it.

i got one because i have bosch 044. i needed it. lesser pumps may not.

do not use any bodgy POS like that on your car.

well, you can if you want, but dont cry if it kills you either money wise or piston wise.

**Turk** · 10-8-07, 4:44

In this setup im not cheaping out on anything that might damage my engine.

If I can use the stock fpr (it is only a walbro 255 intank) I will use it. If I need an aeromotive unit then I will get one. Just an extra $200.
