I think the T517Z is also a TD05-17c but I would need to look into that again.

I'm 99% sure that the T517z isn't a TD05-17C, the 17C compressor is a 12 full blade compressor where as the compressor in the T517z is a 6 full 6 short blade compressor.

Kando Td06 20g 8cm on a rb20 rolled off the dyno this morning. The turbo produced 1.8bar at 5000rpm. Wasn't intentional but it shows how quick the turbo can spool. Especially on a rb20. This was with a stock manifold and an external gate welded to manifold.

Once the crrect spring was installed into the wastegate it had low boost of 8psi and made 188kw without finishing the tune. 14 psi saw 224kw at a very safe AFR and low timing.

The turbo loved it I'm very impressed with what it can do as he's said it is fairly responsive and making good power at low boost td06h-20g with 8cm housing is the go great turbo for 800 with everything

In saying that does that mean you could fit a td06-20g with 10cm housing on 25 with stock manifold or just stock to the td06l2

Will fit nice and snug I have about 6 mm of clearance td06h-20g is the go. lag is the bit where your waiting to get slapped in the face haha but even on my 20 I still have plent of power off boost so a 25 would be better again. Lag = power.

So would a td06h-20g make more power on a rb25 than td06sl2-20g because i was aiming for 300rwkw and was recommended the td06l2 to fit stock manifold but if the td06h will fit with a 10cm housing and I can push a little more power with a tiny little more lag I'd go the td06h

    • The car remains in paint jail. I am now pretty convinced that the whole "RB25 Airboxes are kinda limiting to ~300kw" could be a thing. Also saw a good video from Engine Masters: (Sorry for FB link) (https://www.facebook.com/watch/?ref=search&v=761771519471924&external_log_id=c10bcbb6-2c39-4ff3-9240-287e9921fde6&q=Cold Air Considerations) Where they tested Pod Filter sizes and kept adding bends to a LS3 on an Engine Dyno to find if bends caused power loss. It's a good video worth watching - They did lose ~25hp from making an intake which had 3x90's and a 120 degree. They only lost maybe 1hp with a basic 90. I feel that by sealing up my airbox I have: 1) Created the same restriction a stock airbox would have. 2) Created a very convoluted set of intake 'pipes' by forcing all the air through the ducts. So I am pretty confident I'll be going full circle and have a huge hot air intake pod and actually see a benefit. The air does *not* stay hot once it gets flowing, aided by the ducts, and the pod can then pull air from anywhere. All the posts of yore talk about the stock airbox costing 10-15kw at 300kw+ but you know what? I f**king would very much like that 10-15kw and I remember my own pod filter in engine bay experiences. Turns out the GTT Reo and Headlight brackets really don't allow you to mount GTR items, no matter what the internet says. Various brackets have had to be made up to actually make it fit right for the front bar. Also some idiot mounted a 3L Accusump right where the bumper wants to go, so that has had to be 'relocated' To where, I am still not sure, but it's supposedly mounted in the pictures and I can't see it.
    • Sounds like the oil pressure light is wired into the oil temp sensor... As it warms up, resistance on temp sensor reduces, hence more current can flow and the dash light gets brighter.
    • Got the front subframe and suspension in.    
    • If it's cold in summer, then no issue. If it's cutting out every few seconds and you're not reaching your target temp, then there's an issue. One could be the pressure switch and the other issue could be the temp probe inside the evaporator.
