Bit of a late reply to the actuator modding (haven't been on for like 2 months), but i've found the easiest way is to increase the existing curve on it using a hammer. After I'm done, it looks exactly the same as before I touched it. Neat, but the rod is shorter.

for those wondering like me well why dont I try swapping on a op6 housing onto my stock rb25 turbo

don't (well get a turbo shop to do it for you)

I managed to knock the vg30's rear wheel off when I was removing its rear housing

so asked the guys fixing my head to put the vg rear housing on my 25 turbo for me

only if the felt very confindent seeing as what had just happened to the donor vg30 turbo

picked up my car from the mechanic got one free rev to 3,000 out of it and bang (whistles, looking around from mechanic's)

I wasn't going to bother discussing causes with them

we all know why it let go and they weren't going to be coming to the party

5 hours later (thanks to Huddy and Jarrad) I now have a stock op6 vg30 turbo on my 25 and it is awesome cars got alot more top end than before

however Ive also gone from a 1.5mm h/g to a 1.2mm h/g at the same time so I cant honestly tell you what turbos and whats comp ratio

the vg feels alittle laggier 200 rpm max only though (the higher comp ratio maskes it though) and now pulls cleanly all the way to redline which it didnt before

got a bit dull after 5,500

ps my led taillights and ganadors look phat !

sorry for the long post :D

Switching housings on turbos is not that difficult if you do it the right way. If your mechanic is dodgy, he'll just take your money even if he knows the job will go badly.

If you just try and smash the housing off with a hammer or lever it off with a long metal bar, you'll stuff it up 110% of the time. Everytime, you'll smash the wheel or chip it.

There is a correct way to do it. I've done it so many times. It's not what i'd call easy, but if you do it right, it'll be fine.

I use a wire wheel to scratch all the rust off the join of the housing and catridge. I have this bucket of penetrating oil that I put the whole turbo exhaust housing into for about a week.

Then I loosen the bolts (usually quite nice after the soaking). And I use the bolts to push the housing off.

Before I start the pushing, I use a benzo torch ($20 from bunnings - lasts ages - can do like 20 turbos with it).

Cheers

Is there certain brand for this dump pipe I heard the Just Jap one is shite it apparently doesn't fit right

I got mine custom made by Carline mufflers in Mount Druitt. Call Bruno he's pretty good. It wasnt all that expensive either, cant remember the price he charged me though.

I just replace my turbo with a Hi-flowed GTT and VG-30 rear.

Then added:

Z32

Fuel Reg

Exhaust Cam

Hi-flow Cat

My older mods:

FMIC

BC

Walbro 255L

Split dump

Apexi Power FC

3" Exhuast Tip

16 PSI

With a phat 261RWKW

    • I'm not sure the diode only will give the desired result. I'd probably approach it with a couple of relays (And you still might need a diode too!). You need to be able to break the constant feed from the headlight to the orange corner globe when the indicator is flashing. Not knowing which Skyline we're talking about specifically here too (And it may not matter, but I don't know the R34 column switches) you'd likely need to rewire the stalk, so that the indicator power itself no longer runs through the stalk too, as now you need it able to trigger a relay that will break the constant supply from the headlights to the indicator, then you'll need a separate relay to trigger the indicators to come on (Replacing the internal action of the indicator stalk).
    • Weird story from me My Toyota 86 was with Commbank comprehensive but for market value (who they use to underwrite is unknown) When I munted it beyond financially viable repair in 2020, rear end smashed in to the point it bent the rear quarter and roof, they knew I paid $31k cash for it because I told them, they still paid me out $38k, as all the 2017 limited edition variants with typical Km and condition were going for between $36-41k, so they did weird math and came up with $38k I never officially mentioned any of the mods that I had done, but as they were not the cause of the crash they were not fussed at all, the insurance inspector actually asked if I wanted to replace all the mods with the OEM stuff if I still had it laying around before they took the car I still came out of it behind though, because I had probably dropped $20k in it with the suspension (bent after the prang), wheels (bent as well) and "other" mods, that the inspector asked about But still, as the market value was higher than what I initially paid, and they paid out market value To say I was surprised with the outcome would be an understatement  Weird, but true, but probably just lucky with the inspector on the day I guess  Sadly, I don't think if I munted the old NC1 MX5 I would get the same result Meh, pay to play
    • Well, the car is back, all straight and shiny, for how long for is anyone's guess  After picking it up we went for a bit of a drive, Jebus I really enjoy driving this little thing, hopefully the weather let's us go for a nice long cruise this weekend as it will be out of my hands for at least a few days next week when it heads back into Mania on Monday It's weird, whilst I do always enjoy going for a drive, the NC makes me feel like a kid who has just got his first car, and they just want to drive wherever and whenever they can I really need to look into the MX5 Club of NSW
