I doubt a nut and bolt shop would have them. They normally don't stock that kind of thing. But fluid/hydraulic shops should. I no Pirtek sell them that's where I got mine, check if one is near you.

Sometimes nissan might also stock them. Let me no if you can't track any down

bottom line looks right for water, top line is a fail. i've never had a line with the distributor block on it but that doesn't mean it wont work

Hate to dig up an old thread, but a few people have asked how much boost is safe to run on an n/a to turbo conversion, but there hasnt really been a definitive answer. I am in the middle of doing this exact conversion, and would like to know, I will be running a Bosch 044 pump, R32 GT-R injectors, a Nistune ECU and a T3/T4 on a S2 motor with no decompression plate, but a turbo head gasket. The motor has done 135,000km also.
Cheers
Zac

The turbo headgasket would proberly be 1mm, so it would drop your compression to something in the high 8's, you can do it, but I would proberly only push something like 10psi, and look into finding the best nistune tuner you can find, to make sure theres no detination as that will be cruicial.

If i was you, i would put in a 1.9mm cometic headgasket onto it to drop the compression down more, then you can run more boost, while it being more safter, and knowing the headgasket wont go pop.

Evening Calaisturbo, once more.
I must admit to a bit of confusion, with regards to the high pressure/low pressure fuel pump setup on the VL. As my car is simply an Executive, with the 3 liter N/A engine, do I need to replace both of these units? or am I able to simply upgrade the high pressure (in tank) with a good brand, high performance pump, and take out the low pressure pump altogether?

you can get away with running the standard pumps with low boost for a while, i did and didn't run into any problems. but if you're looking to throw more power at it then a better fuel system is recommended

learn to spell and you might have more luck

again it is not needed unless more power/boost is going to be your aim

a "decompression" plate is not needed for a standard setup

Hey guys

Personally I wouldn't bother with a decomp plate unless the head gasket itself blows. There is no point pulling it all down for something that might not need doing for a year or even two. If you don't thrash your car everywhere then it should last.

As for boost I would say 12 psi would be max but I wouldn't run it daily. I used to run 9psi on low and 12psi on high and I had it for over and year it is has never had any problems

As for fuel, the stock pumps are fine for standard, you will no if you need a upgrade. When I was looking at upgrading my fuel system I was just going to get rid of the external fuel pump and stay with the internal and just replace it to a walbro pump. 6boost suggested this to me and said it has enough power to run high performance vehicles with just the single in tank pump[COLOR="Silver"]

Yeah it is a bit of hit and miss really. I personally would rather be safe than sorry. That's why I didn't want to go over 12psi.
