Wow that is a full on turbocharger Bobby I just realised...76mm inducer and 102mm exducer that should be nearing a four figure hp output.

It's a 68.5mm inducer and a 102mm exducer trim 44 this comp wheel is for high pressure ratio I'd like people to copy this theory. Currently modifying a hks turbo for a friend I'll post some results I won't say for now what I'm doing to it once done I'll let people know a nice mod for hks Kai

The compressor side is less sensitive to A/R changes than the turbine, what you got cooking Bobby? Better performance at higher boost levels...

With this combo the turbo can be at a high pressure ratio with low volume to minimize surge

Seriously thick walled wrist pins you've got there! They look to be at least 1-1.5 mm thicker than a standard pin.

I would have thought you would be using titanium rods too for the deck height you are running as well with this engine.

Is that a GT500 2.8lt crank?

Also, whats with the banjo fittings on the back of the head? External oil supply, rather than through a block restrictor?

Bobby, are the photos that you had of the head showing the water/air reliefs still on this thread? If not, can you post them up again please?

Looks great, like the red :) is that a anti-oil friction coating or it just looks cool?

Hi Ian,

John wanted the thickest wrist pin.

The rods are crower and this should be fine, and wont stretch.

Banjo fitting are the external oil supply that we can control how much we want in the head. Trevor the motor builder has said he wants to see more then std in the head.

Yes the crank is a Gt500 2.8L

      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.
