aahhh, don't ask dude.

we were having disputes with the trubo supplier and when we came to an agreement, the dude from garrett said that he'll send down a A/R .82 which should be fine, but they actually sent down the A/R .63, and before i knew it, it was already on the car.

i think it should be ok though as the same combo with a A/R .63 made ~260rwkw on an RB30ET at ~20psi.

if i'm not happy, i'll be sending it back to sydney and asking for a .82.

That was a little bit of interesting information. Interesting being the amount of extra boost required for the SOHC head on the 3ltr to make 260rwkw.

you're cool dude.

i actually found out from my friend yesterday that the car i mentioned actually ran 18-19psi when it made that power.

also, another car with that same turbo made 285rwkw on 24psi.

i guess the SOHC makes quite a difference to power as compared to DOHC.

actually, my 2L cossie engine (DOHC) made almost the same power a VL RB30ET (SOHC) would make with the same turbo on the same boost, so i'm happy.

btw, the VL i mentioned which made ~260rwkw with the GT3040 (A/R .63) has run an 11.67@115mph at calder park, and fyi, it's a 5 spd manual.

    • Seems like a decent result for a modded JZX110. They are bulky in comparison to the 100 and 90 models (which I'd prefer myself) but they are getting very few and far between here in JP these days. Thanks for the detailed review and the import process into the UK. I also have a car which I'm hoping to export from Japan at some stage so it's good to know if someone from the UK was interested in it. By the way the corrosion underneath is par for the course for cars which were located in/near the mountains or along the Japan sea coastline. They get huge amounts of snow every winter and the sodium chloride is used on the roads. Many cars have some kind of rubber like treatment underneath but they tend to limit it to the wheel arches underbody and fuel tank. Suspension arms and sub-frames will have similar corrosion to your JZX110 which is a common sight. See it all the time and car dealers here generally don't even mention it unless asked.
    • If the sound goes away when you clutch in, the 1.5/2 way diffs are just shit, and you are a normal person. The diff is likely "fine" but driving at anything under 30kmh is a violent horrible experience. It would be exaggerated with solid diff bushings and subframe bushings if you have those.
