Nah, that chart is correct with the A/Rs -> http://www.hksusa.com/categories/more.asp?id=1092 .

It seems that no-one knows the dimensions of the TD06 both 20G + 25G, or T67 (ones quoted are MHI stock). Going to find my verniers and measure them.. one day!

Ok let me first apologise for the measurements given in the earlier post. They are totally incorrect. Here are the correct measurements for the TD06-20G and the T67-25G. The 25G wheel is the same as the one used in the TD07 & the TD06, the difference being in the exhaust housing.

20G: Minor 53mm, Major 68mm, Trim 61

25G Minor 61mm, Major 78mm, Trim 61

Exhaust wheels

TD06: Minor 56mm, Major 65mm, Trim 74

T67: Minor 54mm, Major 62mm, Trim 76

Please note that these measurements may be out by +/- 0.5mm, my battery died in the verniers so had to rely on my one good eye.

Also see the attached pics, from left going in a clockwise direction: T51R Kai, HKS 2835. HKS 3037S, T67-25G, TD06-20G. There's alot of differences in the design of all these turbos as well....

  • 2 weeks later...
Both the Trust turbos have 10cm rears, they are pretty much identical. The wheels are totally different designs, with the T67 being able to flow alot more gas, even though the wheel is slightly smaller.

So considering exhaust wheels are much the same diam, though the T67 looks as though it will flow a lot more (pitch of blades)...im thinking that the T67-25G with an 8cm housing cant be any worse then my current setup remembering lat time you were in the car i had a 10cm housing, and the thing still had marginal tune?

So with cam gear, some higher lift cams and PFc do you think id be able to get 1bar out of the T67-25G by 4,500rpm? mmm i suppose there is only one way to find out :D

    • Hi guys, just after some guidance with an R34 sunroof that has stopped working correctly. It still opens and closes perfectly fine, but it no longer tilts/vents up or down. As a result, the rear of the glass now sags a bit as it drops down slightly in order to retract into the roof, but now it can't pop upwards into a flush position. I’ve probed the pins on the back of the switch connector with a multimeter and it seems like both switches (for open/close and tilt/vent) still work correctly. Any ideas on what it could be, or where I should even start in terms of diagnosing? I'm sure someone's had this issue before but I haven't been able to find anything online relating to this specific issue, most of the issues are with the seals leaking or the motor failing entirely. Thanks in advance!
    • Do you have some data like fuel pressure? It's really hard to say if you're still fighting a fuel system issue at this point. Could be something weird like the FPCM dipping out.
    • Yeah in that case, pulling the dent out. Event a very slight dent can create a lot of work filler-wise and there is a strong chance the panel won't be the factory shape when you are done (as the dent will result in a new high point created somewhere, then everything is brought up to that new high point... but the panel shouldn't be that high if that makes sense).  So you've filled and primed the panel and it is flat, why would you go back and remove the primer and add more filler? 
    • Something else I have been faffing with while the car was off the road is making the AC work. Assuming the car isn't at a thermal limit the idea of having AC while waiting in line to go on track sounds delightful. I have actually been lugging around the weight of the entire system since 2018 when the RB25NEO went in without it working at all.  The main reason was in the first few events before I got around to re-gassing it the rubber hose that runs under the manifold had the factory heat wrap/sleeve fail resulting in this: ~2 years ago I purchased a complete used R32 AC line set but when I finally went to install it the line i needed was different where the expansion section is I found a local place that was able to replace the rubber section and re-crimp. They also added some modern heat sleeve to the hose Tight fit but fingers crossed this is the last physical piece of the puzzle needed
    • the top black section is bonded to the silver section with some form of rubber. I assume to isolated NVH from the box
