Well fast forward to now and I am building a new engine for it. Reason being oil in the coolant. On teardown I found cracks in the deck (marked in green). The oil was seeping pass the cracks at t

Got the wastegate actuators and fitted em up. Was a real pain to do as there is no room, but all good now.

Also got a hold of a nismo cat converter to help free up the exhaust a bit more. I'll fit it up when I can be bothered crawling under the car again.

Sway bars have been ordered in too. :P

Love the work. Was wondering what are the benefits of replacing the wastegate actuators? or is it more of a preventative measure?

I always seem to get a bit of wastegate "flutter" under light acceleration (0.2 - 0.4 bar), even worse after a cold start. and so it stutters and bogs down unless I accelerate more to bring on higher boost.

Does that make sense? It's hard to explain but that's the best way I can describe it. I've read around of people having similar problems on rexies, and some suggest tightening the actuator arm. Is that possible on our skylines?

Thanks Owen!

Only if you replace the actuators with adjustables or get some with a higher spring setting.

I replaced them to get a more stable boost at high boost settings. The standard one's tended to drop in the mid-high range of RPM.

I get the same problem, but at highway speeds in 5-6 gear at light-medium throttle up hills etc.

One fix is to weld a divider into the 'twin turbo pipe' to smooth the airflow from the two turbo outlets. I am yet to get that done.

Some say they get it tuned out?

Well, I'll be seeing you soon then Chris!! That's exactly what I want to get done.

Another piece of the puzzle done now. Got the rims I wanted to get that 'look'.

Genuine Volk CE28N 18x10.5 +18 in gold. Got 275 35 rubber on them. Next plan is to lower it 20mm.

Care to tell where you sourced the wheels from

CE28N looks the bizz too

Ya, it needs some lowering badly

Well done Sean, the car looks tuff with the wheels.

I'm kinda regretting selling them now....

You running any coilovers??

Also have you contemplated colour coding the spoiler between your bumper and lower lip?

It would give it a more aggressive look and seem like the car sits lower aswell....

Very nice car mate, credit to you......

Yep, got em off JAGR33. Wanted them wheels for a while and kept eyeing them off.

Thanks again Jack!! They are a bloody nice wheel! I will not scratch or abuse them, and I'm also going to organise center caps too.

Also importmonster seems to get in some hot wheels in every so often too. They had a different set in silver a while back, but I didn't have the dough at that time!

Still the stock Vspec coilovers, but it will get something good, in time. I have a set of HKS coilovers ready to go, but I don't want a harsh ride.

Was thinking about colour coding the mid lip but I'm still partial to the black look. I do have the paint ready to go though!

Spent a day on the GTR, fitted HKS suspension and brake deflectors. Rear seat scratched the interior trim so I'm :domokun: at myself for that, scratched pretty bad so may have to get another trim panel.

Also pulled of front lip to colour match to car so I will take pics of new stance once finished!

Yep, it's cheaper than getting discs at the moment lolz.

LH rear coilover is knocking, so that was a great buy.... :angry:

Painted the lower lip, but the paint I mixed was probably the wrong tin as it's slightly pink? I'll just take it to a painter next time I have it off.

Pics soon.

So I hear some ass hole is trying to get you to work on his car instead of your own.

PS: I love this car...

As to what yourself and Owen were talking about, that's typical GTR turbo shuffle.

Ha ha, yeah, damn guys wanting engines built.

Hey Steve-o, looked like you got into some trouble on the day lol. When I get the car sorted I'll go. Would of loved to go, but no cash and was working on the R :) I think I like the lip painted, fills it out!

This is lowered to around 115mm on front lip, I like!!

That looks heaps better!! Middle lip painted white and with the coil overs makes the car look much lower to the ground.

Top job, well done.... :thumbsup:

P.s are they CSC brakes?

Thanks, I love the stance but not the ride quality. Yeah they are CSC 356mm discs with 6 pots. Need new discs though, these are stuffed. Got to find out who sells replacements.

Re spray Dave? Your car looks fine?!

I wore the sperm suit on sunday and whipped out the air compressor and my spray gun. Mixed up DG 2PAK white that I had colour matched, with hardener Added thinners but I probably didn't need to. Primed the lip then 800 sand to make it smooth, then 1 light coat, then 2 coats of the white. Nice and smooth/glossy straight out the gun. Fitted it that arvo.

I'm still learning, but I'm pretty good at painting now :thumbsup: Practiced a lot with a spray can when I didn't have a compressor and gun.

Prep work is still the most important, little things like wetting the floor etc.

      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.
