Fantastic work!

I'm still a little bummed I didn't make my return trip home from the Nationals via Sydney, so I could stop by and have a look... though it did shave a few hundred km off the drive.

How far away is the engine build? Have you decided on all the details for it yet?

Meh....the reality is that the car must have fallen short of expectations Really not sure how a full tune can drag out for 2 years... so claims that the build was f1 spec, just musn't show on the dyn

Thanks Ian.

It s ok maybe nextime you are in sydney John would be more then happy to show you the fab work and what his aiming to build.

The build has been slow, just getting the head ready for assembly as the bottom end is completed. ( Still trying to get pics for this )

All the other aspects of the car are ready and up to date, just need to drop the motor im and start finishing this build.

It's almost like the next pics you post couldn't possibly be better than what you've already posted...

But No.... They just get more awesome!

Have you weighted the manifold/turbo/gate assembly? Noted John thought it wouldn't need any brace/supporting. Just wondering what the actual weight is :)

The weight of the manifold with just the wastegates bolted on is about 7kg.

Spoke to John about the brace, he will be adding a brace or bracing system to the manifold however at this point of time he has not stated where. Once he does i will update you.

Cool thanks :) is it for clearance reasons. My 1jz manifold does the opposite (faces the comp cover away)

The turbo was rotated towards the rocker cover to achieve the best exit of the turbo that was not a 90 degree bend like everyone else has, john has said 90 degree bend can cause upto 15% loss in efficiency of the turbo.

Sweet :)

I remember earlier in the thread it was stated it wasn't needed, perhaps that was only in early stages. 7kg + turbo would be quite a hefty end result.

Be interesting to see where it's braced and what not - look forward to that update :thumbsup:

fyp

heat + stainless steel = bending.

good welds will not stop it.

keep us updated. :)

This pic will answer your question

The red lines drawn on the inlet are approximate anti-surge slot locations to be milled out?

The red lines are for the installation of a plunger infront of the turbo.

John does not like anti surge slots as this also reduces the efficiency of the turbo.

      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.
