yeh right... never thougth about that.

im getting a bosch 040 pump to put in there this week, reason being i had to change over the fuel filter the other day and it was the factory stock filter! i weighed about 1 kilo, full of crap, so i figured its about time to change the pump as well. should i get an AFR plot before changing the pump?

Front and dumps+mo boost then dyno...then wait for the ceramics to let go after a few days, week, months whatever and then your in the club :)

Seriously I'd get the tune sorted then leave it alone...if you want to keep money in you pocket that is. Pump's a good idea though.

you'll probably find that Mine's ECU of yours is tuned to Jap petrol (102 octane most likely) and it'll be running lean. A fuel pressure regulator is probably needed, and if you're upgrading the fuel pump make sure the relay is in good order, making a full 12V at the pump. As for the turbos, its just a matter of time. I've heard of people running 14psi consistently on the ceramics with no troubles at all. Me on the other hand, as soon as I took it to the track they clapped out after the 5th lap. $10k later and its back on the road :worship:

As for the dumps, fit them when your turbos eventually blow, it wouldn't be worth the cost of labour otherwise.

When one of my ceramics let go, 13psi, I went for 2860R-5's. There are a few knowledgeable guys here who believe that destroying a ceramic is a death sentence. My engine tested fine and continues to have good oil pressure after 17K on the new turbs. Cat...what is that lol

      I am currently going this route. I am curious how much horse power you put behind the cut bell housing? Collins was telling me I am going to crack it and bluh bluh bluh. Because I didn’t buy the custom fly wheel from him. I am looking for somewhere around like 500 hp

      Thanks @PranK for the updated member status, much appreciated! 👍🏼 Now, about those pics… Unfortunately I could only find ones that I took in the dark. I was soon to discover that underneath it wasn’t in the best shape, but it was mine and that’s all I cared about at the time 😆

      A little PU bush story

      By GTSBoy · Posted

      Oh, and only having done this task yesterday, I've now driven the car ~60km since, and while it is hard to avoid placebo effect and confirmation bias, I reckon that some annoyances I had with the way the car has been behaving have improved. Which....kinda makes sense, I guess. If the bushes were really stiff and resisting rotation, they would have been contributing to the effective wheel rate. And if it was more so on one side (which it was, because one side was worse than the other) then.... you might imagine that the additional rate would be asymmetric, and potentially even different between compression and rebound. And so... the car has been twitchy at higher speeds - like freeway on ramps. It really shouldn't be. The wheel alignment is good and there are no (other) known problems elsewhere in the suspension. But at 90-100 on a long sweeping ramp, tiny steering wheel motions would make it feel like it wanted to rear steer. Quite nervous. At lower speeds it would heave about in a manner that it didn't use to. Didn't want to put power down, etc etc. Now...seems to behave better. Am going to have to concentrate on the various corners where it has exhibited weirdness, on the rare occasions when I can get a decent run at them without Methanial getting in the way in his D-Max/Ranger/LDV Van/etc.
