Arashi TD06SL2 20G Turbo Review

[Juan Ma]

Installed a Ball Bearing Arashi 20g. Today during tuning the turbo was overboosting to over 25 plus punds. Not sure why because according to specs, the turbo has a 1.1bar actuator on it, which equates to 15 psi. Is it possible an incorrect spring was used?

OP here. Still lovin’ it @ 146K miles.

[Jchustla]

Been running mines now for 3+ years 30K+ miles with no issues.

Running EWG and meth injection at 24 psi making 415 whp and 380 wtq Dynojet (I have seen 440whp and 390 wtq on road dyno on a much cooler night).

Turbo is about capped out there in terms of efficiency.

Tuner says to go with td05 20g as td06sl2 is laggy for 350whp
But what about the ball bearing td06sl2?

i have the journal bearing with 11 blade exhaust and its about as responsive as the stock vf48...when it goes i am going to do the same turbo ball bearing and would expect it to spool a little better!

I had Ball Bearing TD06SL2 20G and now I have TD05H 20G, about 250RPM difference is spool on EL headers

[Timmer24]

Weird

[Jedi03]

do you prefer the 5 or 6? And on EL i agree the spool is much better!

Just making sure I am reading this right, so you are saying your current TD05-20G spool 250rpm faster than your previous TD06SL2-20G ?

Been running my td06 sl2 20g now for about 20,000 miles now all in all great turbo for the money. Took me a little to get used to driving it with the lag at first, but once your able to keep it in that sweet spot with your shifts its a beast. I am thinking about switching out the compressor housing to a 3in anti surge style to see if it helps it with lag will update this thread if I do.

I see you're running this turbo with a 2.0 engine. How many psi are you boosting ? What is your boost pressure at 3500 rpm? 4000 rpm ? Just trying to get a sense on how boost build with this turbo. Thx.

Have you consider swapping out the journey bearing cartridge with a KBT bolt-on ball bearing to help with spool, I think Arashi offer this as an option.

This on a 2.5l fully built with FMIC it hits 21psi at 3700 sometimes a little earlier depends on my driving. Will definitely hit higher boost but my trans will definitely not handle what this turbo has potential to do. Holds my 19 psi I have it set at til 7000 rpms no problem and pulls great. I stuck with a journal style turbo for reliability I drive too many miles to have to worry about rebuilding turbo every 20,000 miles

Is this statement based on personal experiences ? Or is this type of failure specific to Subaru or a particular brand of turbo ? I ask because a quick Google didn't show a lots of hits.


If this is a concern, check out RHB turbo in Canada. They have a patented triple ball bearing design that float on oil film that might just be the best of both worlds.

For anyone that’s ordered a turbo from arashi how’d it go and how was communication. I’m trying to order one right now but having a lot of problems. Their website is having issues and I’ve gotten a few messages back and forth through Instagram dms, I’ve sent multiple emails but nothing in response. Any tips?

[Jedi03]

Just did a little research on the dsm site, td05 spools faster an td06 has more topend
