gday people just wondering what you all think of malpassi adjustable fuel pres regulators. I just bought one for my vl turbo and it going on with a surge tank and a bosch 984 pump. However i have been told that these fuel pres regulators are shit and you have to adjust them every week etc...??? is this true??? :(

I've used a Malpassi adj fuelregulator i min old Opel Astra Turbo and would never in my life put it in my Skyline. I had some problems with mine.

I used it for about 3 months and had to adjust it 5-6 times before I threw it out for an SX fuelregulator that worked perfectly.

Yeah mines fine. However we did have a black toped one on for a while, and that caused some major issues. Replaced it with a new silver topped one and fine and dandy. You can watch the gauge all day, heat changes etc, its fine. But as with everything I think age misstreatment and bad luck can play a part, and you never hear people whining about how GOOD a product is, only how bad one is.

Okay, let's up the ante... Why put one on at all?

Reading through the previous threads, the debate is still inconclusive as to whether the stock unit is just as good. It sounds like it is capable up to a point, but where is that point?

I have been given a fuel reg (I was told it's a Malpassi but it has no markings) and I really don't want to put it on because of all the problems being experienced by others. The car is my daily driver and reliablity for me is a bigger issue than having a fuel reg that may not be any better than the stock item.

Why fix it if it ain't broke?

Can we put this one to bed?

    • Hmm. I should have thought of the clutch bleeding issue. It should be #1 thought for "can't select gears". As to "sounds like the top".....have you actually gone out with the stethoscope and tried to pin it down any more than that? And, buy or borrow a timing light, and set the timing properly.
    • I don’t really have any ideas how to set the timing on the CAS 😂, sounds like the top, sounds like it maybe misfiring as well as ticking,  got the box sorted 😌, must of been a air bubble on the clutch side
    • Use a 2' length of hose (that's 2 foot, not 2 inches) as a stethoscope to localise the source of the ticking. From cam covers? From exhaust or turbo manifold gasket? From injectors? From lower down in the engine? Etc. Use a timing light to set the timing. Put Redline Lightweight Shockproof in the box. It's not the very best thing for the box, but it will take a box that refuses to engage a gear with other oil, and make it engage a gear. I had to put it in when I installed the R33 box I have in my car. It would not select ANY gear when running. Smurf jizz made it work. That was >10 years ago and I still use it. I'm stuck with it now. Failing that - rebuild the box.
    • Well done Duncan. The fuel tank bulkhead lid is also in great condition (some of mine were stuffed). These are now out of production and good ones like that are becoming hard to come by.
    • Wow that's a steal, you've done well there.
